CHECKING OIL LEVEL

ADDING WASHER FLUID

MAINTENANCE-FREE BATTERY

To ensure proper engine lubrication, the engine oil must

be maintained at the correct level. Check the oil level at

regular intervals, such as every fuel stop. The best time to

check the engine oil level is about five minutes after a fully

warmed up engine is shut off.

The fluid reservoir is located under the hood and the fluid

level should be checked at regular intervals. Fill the

reservoir with windshield washer solvent only (not radiator

antifreeze). When refilling the washer fluid reservoir, take

some washer fluid and apply it to a cloth or towel and wipe

the wiper blades clean. This will help blade performance.

Your vehicle is equipped with a maintenance-free battery.

You will never have to add water, and periodic

maintenance is not required.

WARNING!

Checking the oil while the vehicle is on level ground will

improve the accuracy of the oil level readings.

 Battery fluid is a corrosive acid solution and can burn

or even blind you. Do not allow battery fluid to

contact your eyes, skin, or clothing. Do not lean over

a battery when attaching clamps. If acid splashes in

eyes or on skin, flush the area immediately with large

amounts of water Ú page 325.

To prevent freeze-up of your windshield washer system in

cold weather, select a solution or mixture that meets or

exceeds the temperature range of your climate. This rating

information can be found on most washer fluid containers.

There are four possible dipstick types:

 Crosshatched zone.

 Crosshatched zone marked SAFE.

WARNING!

 Crosshatched zone marked with MIN at the low end of

the range and MAX at the high end of the range.

 Battery gas is flammable and explosive. Keep flame

or sparks away from the battery. Do not use a

booster battery or any other booster source with an

output greater than 12 Volts. Do not allow cable

clamps to touch each other.

Commercially available windshield washer solvents are

flammable. They could ignite and burn you. Care must

be exercised when filling or working around the washer

solution.

 Crosshatched zone marked with dimples at the MIN

and the MAX ends of the range.

NOTE:

Always maintain the oil level within the crosshatch

markings on the dipstick.

 Battery posts, terminals, and related accessories

contain lead and lead compounds. Wash hands after

handling.

After the engine has warmed up, operate the defroster for

a few minutes to reduce the possibility of smearing or

freezing the fluid on the cold windshield. Windshield

washer solution used with water as directed on the

container, aids cleaning action, reduces the freezing point

to avoid line clogging, and is not harmful to paint or trim.

Adding 1 qt (1.0 L) of oil when the reading is at the low end

of the dipstick range will raise the oil level to the high end

of the range marking.

CAUTION!

Overfilling or underfilling the crankcase will cause oil

aeration or loss of oil pressure. This could damage

your engine.

SERVICING AND MAINTENANCE 341

NOTE:

VEHICLE MAINTENANCE

CAUTION!

Hemi engines (5.7L) at times can tick right after startup

and then quiet down after approximately 30 seconds. This

is normal and will not harm the engine. This characteristic

can be caused by short drive cycles. For example, if the

vehicle is started then shut off after driving a short

distance. Upon restarting, you may experience a ticking

sound. Other causes could be if the vehicle is unused for

an extended period of time, incorrect oil, extended oil

changes or extended idling. If the engine continues to tick

or if the Malfunction Indicator Light (MIL) comes on, see

the nearest authorized dealer.

An authorized dealer has the qualified service personnel,

special tools, and equipment to perform all service

operations in an expert manner. Service Manuals are

available which include detailed service information for

your vehicle. Refer to these Service Manuals before

attempting any procedure yourself.

 It is essential when replacing the cables on the

battery that the positive cable is attached to the posi-

tive post and the negative cable is attached to the

negative post. Battery posts are marked positive (+)

and negative (-) and are identified on the battery

case. Cable clamps should be tight on the terminal

posts and free of corrosion.

NOTE:

Intentional tampering with emissions control systems may

void your warranty and could result in civil penalties being

assessed against you.

 If a “fast charger” is used while the battery is in the

vehicle, disconnect both vehicle battery cables

before connecting the charger to the battery. Do not

use a “fast charger” to provide starting voltage.

WINDSHIELD WIPER BLADES

If your vehicle is equipped with a Stop/Start, belt must be

replaced with an OEM grade Mopar® belt.

Clean the rubber edges of the wiper blades and the

windshield periodically with a sponge or soft cloth and a

mild nonabrasive cleaner. This will remove accumulations

of salt or road film.

Some conditions can be caused by a faulty component

such as a belt pulley. Belt pulleys should be carefully

inspected for damage and proper alignment.

Operation of the wipers on dry glass for long periods may

cause deterioration of the wiper blades. Always use

washer fluid when using the wipers to remove salt or dirt

from a dry windshield.

Belt replacement on some models requires the use of

special tools, we recommend having your vehicle serviced

at an authorized dealer.

BODY LUBRICATION

Avoid using the wiper blades to remove frost or ice from

the windshield. Keep the blade rubber out of contact with

petroleum products such as engine oil, gasoline, etc.

Locks and all body pivot points, including such items as

seat tracks, door hinge pivot points and rollers, liftgate,

tailgate, decklid, sliding doors and hood hinges, should be

lubricated periodically. Use a lithium-based grease, such

as Mopar® Spray White Lube to assure quiet, easy

operation and to protect against rust and wear. Prior to the

application of any lubricant, the parts concerned should

be wiped clean to remove dust and grit; after lubricating

excess oil and grease should be removed. Particular

attention should also be given to hood latching

components to ensure proper function. When performing

other underhood services, the hood latch release

mechanism, and safety catch should be cleaned and

lubricated.

NOTE:

Life expectancy of wiper blades varies depending on

geographical area and frequency of use. If chattering,

marks, water lines or wet spots are present, clean the

wiper blades or replace as necessary.

Accessory Belt (Serpentine Belt)

Conditions that would require replacement:

 Rib chunking (one or more ribs has separated from

belt body)

The wiper blades and wiper arms should be inspected

periodically, not just when wiper performance problems

are experienced. This inspection should include the

following points:

 Rib or belt wear

 Longitudinal belt cracking (cracks between two ribs)

 Belt slips

8

 Wear or uneven edges

 Foreign material

 Groove jumping (belt does not maintain correct posi-

tion on pulley)

 Hardening or cracking

 Deformation or fatigue

The external lock cylinders should be lubricated twice a

year, preferably in the Autumn and Spring. Apply a small

amount of a high quality lubricant, such as Mopar® Lock

Cylinder Lubricant directly into the lock cylinder.

 Belt broken

 Noise (objectionable squeal, squeak, or rumble is

heard or felt while drive belt is in operation)

If a wiper blade or wiper arm is damaged, replace the

affected wiper arm or blade with a new unit. Do not

attempt to repair a wiper arm or blade that is damaged.

NOTE:

Identify and correct problem before new belt is installed.

12 months (before the onset of freezing weather, where

applicable). If the engine coolant is dirty or rusty in

appearance, the system should be drained, flushed and

refilled with fresh coolant. Check the front of the A/C

condenser (if equipped) or radiator for any accumulation

of bugs, leaves, etc. If dirty, clean by gently spraying water

from a garden hose vertically down the face of the A/C

condenser (if equipped) or the back of the radiator core.

in gear and the vehicle is in motion.

 Do not try to start the vehicle by pushing or towing the

vehicle.

 Do not idle the engine with any ignition components

disconnected or removed, such as when diagnostic

testing, or for prolonged periods during very rough idle

or malfunctioning operating conditions.

 Damage to the catalytic converter can result if your

vehicle is not kept in proper operating condition. In

the event of engine malfunction, particularly

involving engine misfire or other apparent loss of

performance, have your vehicle serviced promptly.

Continued operation of your vehicle with a severe

malfunction could cause the converter to overheat,

resulting in possible damage to the converter and

vehicle.

COOLING SYSTEM

Check the engine cooling system hoses for brittle rubber,

cracking, tears, cuts and tightness of the connection at

the coolant recovery bottle and radiator. Inspect the entire

system for leaks.

WARNING!

 You or others can be badly burned by hot engine

coolant (antifreeze) or steam from your radiator.

If you see or hear steam coming from under the

hood, donotopen the hood until the radiator has had

time to cool. Never open a cooling system pressure

cap when the radiator or coolant bottle is hot.

DO NOT REMOVE THE COOLANT PRESSURE CAP WHEN

THE COOLING SYSTEM IS HOT.

Cooling System — Drain, Flush And Refill

NOTE:

Some vehicles require special tools to add coolant

properly. Failure to fill these systems properly could

lead to severe internal engine damage. If any coolant

is needed to be added to the system please contact

an authorized dealer.

Under normal operating conditions, the catalytic converter

will not require maintenance. However, it is important to

keep the engine properly tuned to assure proper catalyst

operation and prevent possible catalyst damage.

 Keep hands, tools, clothing, and jewelry away from

the radiator cooling fan when the hood is raised. The

fan starts automatically and may start at any time,

whether the engine is running or not.

NOTE:

8

Intentional tampering with emissions control systems can

result in civil penalties being assessed against you.

If the engine coolant (antifreeze) is dirty or contains visible

sediment, have an authorized dealer clean and flush with

OAT coolant (conforming to MS.90032).

 When working near the radiator cooling fan, discon-

nect the fan motor lead or turn the ignition to the OFF

mode. The fan is temperature controlled and can

start at any time the ignition is in the ON mode.

In unusual situations involving grossly malfunctioning

engine operation, a scorching odor may suggest severe

and abnormal catalyst overheating. If this occurs, stop the

vehicle, turn off the engine and allow it to cool. Service,

including a tune-up to manufacturer's specifications,

should be obtained immediately.

For the proper maintenance intervals Ú page 334.

350 SERVICING AND MAINTENANCE

NOTE:

Selection Of Coolant

For further information Ú page 396.

NOTE:

Adding Coolant

 It is the owner's responsibility to maintain the proper

level of protection against freezing according to the

temperatures occurring in the area where the vehicle is

operated.

Your vehicle has been built with an improved engine

coolant (OAT coolant conforming to MS.90032) that

allows extended maintenance intervals. This engine

coolant (antifreeze) can be used up to 10 years or

150,000 miles (240,000 km) before replacement.

To prevent reducing this extended maintenance period, it

is important that you use the same engine coolant

(OAT coolant conforming to MS.90032) throughoutthelife

of your vehicle.

 Mixing of engine coolant (antifreeze) other than

specified Organic Additive Technology (OAT) engine

coolant, may result in engine damage and may

decrease corrosion protection. OAT engine coolant is

different and should not be mixed with Hybrid Organic

Additive Technology (HOAT) engine coolant or any

“globally compatible” coolant. If a non-OAT engine

coolant is introduced into the cooling system in an

emergency, the cooling system will need to be drained,

flushed, and refilled with fresh OAT coolant

 Some vehicles require special tools to add coolant

properly. Failure to fill these systems properly could

lead to severe internal engine damage. If any coolant is

needed to be added to the system, please contact an

authorized dealer.

Please review these recommendations for using Organic

Additive Technology (OAT) engine coolant that meets the

requirements of the manufacturer Material Standard

MS.90032. When adding engine coolant:

 Mixing engine coolant types is not recommended and

can result in cooling system damage. If HOAT and OAT

coolant are mixed in an emergency, have an authorized

dealer drain, flush, and refill with OAT coolant

(conforming to MS.90032), by an authorized dealer as

soon as possible.

(conforming to MS.90032) as soon as possible.

 We recommend using Mopar® Antifreeze/Coolant

10 Year/150,000 Mile (240,000 km) Formula OAT

that meets the requirements of the manufacturer

Material Standard MS.90032.

Cooling System Pressure Cap

 Do not use water alone or alcohol-based engine

coolant products. Do not use additional rust inhibitors

or anti-rust products, as they may not be compatible

with the radiator engine coolant and may plug the

radiator.

The cap must be fully tightened to prevent loss of engine

coolant (antifreeze), and to ensure that engine coolant

will return to the radiator from the coolant expansion

bottle/recovery tank (if equipped).

 Mix a minimum solution of 50% OAT engine coolant

that meets the requirements of the manufacturer

Material Standard MS.90032 and distilled water.

Use higher concentrations (not to exceed 70%) if

temperatures below −34°F (−37°C) are anticipated.

Please contact an authorized dealer for assistance.

 This vehicle has not been designed for use with

propylene glycol-based engine coolant. Use of

propylene glycol-based engine coolant is not recom-

mended.

The cap should be inspected and cleaned if there is any

accumulation of foreign material on the sealing surfaces.

 Use only high purity water such as distilled or deionized

water when mixing the water/engine coolant solution.

The use of lower quality water will reduce the amount

of corrosion protection in the engine cooling system.

 Some vehicles require special tools to add coolant

properly. Failure to fill these systems properly could

lead to severe internal engine damage. If any coolant is

needed to be added to the system please contact an

authorized dealer.

SERVICING AND MAINTENANCE 351

Checking Coolant Level — 3.6L Engine

WARNING!

The level of the coolant in the pressurized coolant bottle

should be between the “MIN” and “MAX” range on the

bottle when the engine is cold.

 Do not open a hot engine cooling system. Never add

engine coolant (antifreeze) when the engine is over-

heated. Do not loosen or remove the cap to cool an

overheated engine. Heat causes pressure to build up

in the cooling system. To prevent scalding or injury,

do not remove the pressure cap while the system is

hot or under pressure.

The radiator normally remains completely full, so there is

no need to remove the cap unless checking for coolant

freeze point or replacing engine coolant (antifreeze).

Advise your service attendant of this. As long as the engine

operating temperature is satisfactory, the coolant bottle

need only be checked once a month. When additional

engine coolant is needed to maintain the proper level, it

should be added to the coolant bottle. Do not overfill.

 Do not use a pressure cap other than the one speci-

fied for your vehicle. Personal injury or engine

damage may result.

Coolant Reservoir Dipstick

3. Check the coolant level on the dipstick.

Checking Coolant Level — 5.7L Engines

Disposal Of Used Coolant

The radiator normally remains completely full, so there is

no need to remove the radiator cap unless checking for

engine coolant (antifreeze) freeze point or replacing

engine coolant. Advise your service attendant of this.

As long as the engine operating temperature is

satisfactory, the coolant bottle need only be checked

once a month.

With the engine off and cold, the level of the engine

coolant should be between the ADD and SAFE range on

the dipstick.

Used ethylene glycol-based coolant (antifreeze) is a

regulated substancerequiring proper disposal. Check with

your local authorities to determine the disposal rules for

your community. To prevent ingestion by animals or

children, do not store ethylene glycol-based coolant in

open containers or allow it to remain in puddles on the

ground, clean up any ground spills immediately.

To check the coolant level:

1. Open the coolant reservoir.

2. Lift and remove the plastic dipstick from the

reservoir neck.

When additional engine coolant is needed to maintain the

proper level, it should be added to the coolant bottle.

Do not overfill.

If ingested, seek emergency assistance immediately.

352 SERVICING AND MAINTENANCE

 Keep the front of the radiator clean. If your vehicle is

equipped with air conditioning, keep the front of the

condenser clean.

Cooling System Notes

NOTE:

Fluid Level Check — Brake Master Cylinder

The fluid level of the brake master cylinder should be

checked whenever the vehicle is serviced, or immediately

if the Brake System Warning Light is on. If necessary, add

fluid to bring level within the designated marks on the side

of the reservoir of the brake master cylinder. Be sure to

clean the top of the master cylinder area before removing

cap. With disc brakes, fluid level can be expected to fall as

the brake pads wear. Brake fluid level should be checked

when pads are replaced. If the brake fluid is abnormally

low, check the system for leaks Ú page 397.

When the vehicle is stopped after a few miles/kilometers

of operation, you may observevapor coming from the front

of the engine compartment. This is normally a result of

moisture from rain, snow, or high humidity accumulating

on the radiator and being vaporized when the thermostat

opens, allowing hot engine coolant (antifreeze) to enter

the radiator.

 Do not change the thermostat for Summer or Winter

operation. If replacement is ever necessary, install

ONLY the correct type thermostat. Other designs may

result in unsatisfactory engine cooling performance,

poor gas mileage, and increased emissions.

BRAKE SYSTEM

In order to ensure brake system performance, all brake

system components should be inspected periodically

Ú page 334.

If an examination of your engine compartment shows no

evidence of radiator or hose leaks, the vehicle may be

safely driven. The vapor will soon dissipate.

WARNING!

 Do not overfill the coolant expansion bottle.

 Use only manufacturer's recommended brake fluid

Ú page 397. Using the wrong type of brake fluid can

severely damageyour brake system and/or impair its

performance. The proper type of brake fluid for your

vehicle is also identified on the original factory

installed hydraulic master cylinder reservoir.

 Check the coolant freeze point in the radiator and in

the coolant expansion bottle. If engine coolant needs

to be added, the contents of the coolant expansion

bottle must also be protected against freezing.

WARNING!

Riding the brakes can lead to brake failure and possibly

a collision. Driving with your foot resting or riding on the

brake pedal can result in abnormally high brake

temperatures, excessive lining wear, and possible brake

damage. You would not have your full braking capacity

in an emergency.

 If frequent engine coolant additions are required, the

cooling system should be pressure tested for leaks.

 To avoid contamination from foreign matter or

moisture, use only new brake fluid or fluid that has

been in a tightly closed container. Keep the master

cylinder reservoir cap secured at all times. Brake

fluid in an open container absorbs moisture from the

air resulting in a lower boiling point. This may cause

it to boil unexpectedly during hard or prolonged

braking, resulting in sudden brake failure. This could

result in a collision.

 Maintain engine coolant concentration at a minimum

of 50% OAT coolant (conforming to MS.90032) and

distilled water for proper corrosion protection of your

engine which contains aluminum components.

 Make sure that the coolant expansion bottle overflow

hoses are not kinked or obstructed.

SERVICING AND MAINTENANCE 353

Fluid Level Check

Selection Of Lubricant

WARNING!

The fluid level is preset at the factory and does not require

adjustment under normal operating conditions. Routine

fluid level checks are not required, therefore the

transmission has no dipstick. An authorized dealer can

check your transmission fluid level using special

service tools.

It is important to use the proper transmission fluid to

ensure optimum transmission performance and life. Use

only the manufacturer recommended transmission fluid

Ú page 397. It is important to maintain the transmission

fluid at the correct level using the recommended fluid. No

chemical flushes should be used in any transmission; only

the approved lubricant should be used.

 Overfilling the brake fluid reservoir can result in

spilling brake fluid on hot engine parts, causing the

brake fluid to catch fire. Brake fluid can also damage

painted and vinyl surfaces, care should be taken to

avoid its contact with these surfaces.

 Do not allow petroleum based fluid to contaminate

the brake fluid. Brake seal components could be

damaged, causing partial or complete brake failure.

This could result in a collision.

If you notice fluid leakage or transmission malfunction,

visit an authorized dealer immediately to have the

transmission fluid level checked. Operating the vehicle

with an improper fluid level can cause severe

transmission damage.

CAUTION!

Using a transmission fluid other than the

manufacturer’s recommended fluid may cause

deterioration in transmission shift quality and/or torque

converter shudder Ú page 397.

AUTOMATIC TRANSMISSION

CAUTION!

Special Additives

If a transmission fluid leak occurs, visit an authorized

dealer immediately. Severe transmission damage may

occur. An authorized dealer has the proper tools to

adjust the fluid level accurately.

The manufacturer stronglyrecommends against using any

special additives in the transmission. Automatic

Transmission Fluid (ATF) is an engineered product and its

performance may be impaired by supplemental additives.

Therefore, do not add any fluid additives to the

transmission. Avoid using transmission sealers as they

may adversely affect seals.

REAR AXLE AND 4X4 FRONT DRIVING

AXLE FLUID LEVEL

For normal service, periodic fluid level checks are not

required. When the vehicle is serviced for other reasons

the exterior surfaces of the axle assembly should be

inspected. If gear oil leakage is suspected inspectthefluid

level Ú page 397. This inspection should be made with

the vehicle in a level position.

Fluid And Filter Changes

Under normal operating conditions, the fluid installed at

the factory will provide satisfactory lubrication for the life

of the vehicle.

8

CAUTION!

Routine fluid and filter changes are not required. However,

change the fluid and filter if the fluid becomes

contaminated (with water, etc.), or if the transmission is

disassembled for any reason.

Do not use chemical flushes in your transmission as the

chemicals can damage your transmission components.

Such damage is not covered by the New Vehicle Limited

Warranty.

The fluid level should be even with the bottom of the fill

hole (within 1/4 in (6.4 mm) of edge of hole) for the front

axle and rear axle.

For further information Ú page 397.

This fluid level can be checked by removing the filler plug.

The fluid level should be to the bottom edge of the filler

plug hole (or within 1/8 inch of the bottom) with the

vehicle in a level position.

WARNING!

 When replacing a blown fuse, always use an appro-

priate replacement fuse with the same amp rating as

the original fuse. Never replace a fuse with another

fuse of higher amp rating. The use of a fuse with a

rating other than indicated may result in a dangerous

electrical system overload. If a properly rated fuse

continues to blow, it indicates a problem in the circuit

that must be corrected. Never replace a blown fuse

with metal wires or any other material. Do not place

a fuse inside a circuit breaker cavity or vice versa.

Failure to use proper fuses may result in serious

personal injury, fire and/or property damage.

NOTE:

The presence of water in the gear lubricant will result in

corrosion and possible failure of differential components.

Operation of the vehicle in water, as may be encountered

in some off-highway types of service, will require draining

and refilling the axle to avoid damage.

Drain And Refill

For the proper maintenance intervals Ú page 334.

Selection Of Lubricant

Use only the manufacturer recommended fluid

Ú page 397.

Limited-Slip Differentials

Rear axles equipped with a Limited Slip Differential

require that 5 oz. (148 ml) Mopar® Limited Slip Additive

be added to the gear lubricant Ú page 397. The Mopar®

Limited Slip Additive should be added to the gear lubricant

whenever a fluid change is made to an axle equipped with

a Limited Slip Differential.

 Before replacing a fuse, make sure that the ignition

is off and that all the other services are switched off

and/or disengaged.

NOTE:

When refilling a limited slip differential axle which requires

a friction modification additive, the additive should be

added before the gear lubricant to ensure proper

additive fill.

 If the replaced fuse blows again, contact an

authorized dealer.

 If a general protection fuse for safety systems (air

bag system, braking system), power unit systems

(engine system, transmission system) or steering

system blows, contact an authorized dealer.

Tire Terminology And Definitions

Term

Definition

B-pillar

The vehicle B-pillar is the structural member of the body located behind the front door.

Cold tire inflation pressure is defined as the tire pressure after the vehicle has not been driven for at least

three hours, or driven less than 1 mile (1.6 km) after sitting for a minimum of three hours. Inflation

pressure is measured in units of psi (pounds per square inch) or kPa (kilopascals).

Cold Tire Inflation Pressure

The maximum inflation pressure is the maximum permissible cold tire inflation pressure for this tire.

The maximum inflation pressure is molded into the sidewall.

Maximum Inflation Pressure

Recommended Cold Tire Inflation Pressure

Tire Placard

The manufacturer’s recommended cold tire inflation pressure as shown on the tire placard.

A label permanently attached to the vehicle describing the vehicle’s loading capacity, the original

equipment tire sizes and the recommended cold tire inflation pressures.

374 SERVICING AND MAINTENANCE

This placard tells you important information about the:

1. Number of people that can be carried in the vehicle.

2. Total weight your vehicle can carry.

Tire Loading And Tire Pressure

NOTE:

The proper cold tire inflation pressure is listed on the

driver’s side B-pillar or the rear edge of the driver's side

door.

3. Tire size designed for your vehicle.

4. Cold tire inflation pressures for the front, rear, and

spare tires.

Check the inflation pressure of each tire, including the

spare tire (if equipped), at least monthly and inflate to the

recommended pressure for your vehicle.

Loading

The vehicle maximum load on the tire must not exceed the

load carrying capacity of the tire on your vehicle. You will

not exceed thetire's load carrying capacity if you adhere to

the loading conditions, tire size, and cold tire inflation

pressures specified on the Tire And Loading Information

Placard in Vehicle Loading Ú page 172.

Example Tire Placard Location (B-pillar)

NOTE:

Under a maximum loaded vehicle condition, Gross Axle

Weight Rating (GAWR) for the front and rear axles must

not be exceeded.

Example Tire Placard Location (Door)

To determine the maximum loading conditions of your

vehicle, locate the statement “The combined weight of

occupants and cargo should never exceed XXX kg or XXX

lbs” on the Tire And Loading Information Placard. The

combined weight of occupants, cargo/luggage and trailer

tongue weight (if applicable) should never exceed the

weight referenced here.

Tire And Loading Information Placard

SERVICING AND MAINTENANCE 375

Metric Example For Load Limit

Steps For Determining Correct Load Limit—

(5) Determine the combined weight of

luggage and cargo being loaded on the

vehicle. That weight may not safely

exceed the available cargo and luggage

load capacity calculated in Step 4.

For example, if “XXX” amount equals 635 kg and there will

be five 68 kg passengers in your vehicle, the amount of

available cargo and luggage load capacity is 295 kg

(635-340 (5x68) = 295 kg) as shown in step 4.

(1) Locate the statement “The combined

weight of occupants and cargo should

never exceed XXX kg or XXX lbs.” on your

vehicle's placard.

NOTE:

 If your vehicle will be towing a trailer, load from your

trailer will be transferred to your vehicle. The following

table shows examples on how to calculate total load,

cargo/luggage, and towing capacities of your vehicle

with varying seating configurations and number and

size of occupants. This table is for illustration purposes

only and may not be accurate for the seating and load

carry capacity of your vehicle.

(6) If your vehicle will be towing a trailer,

load from your trailer will be transferred

to your vehicle. Consult this manual to

determine how this reduces the

available cargo and luggage load

capacity of your vehicle.

(2) Determine the combined weight of

the driver and passengers that will be

riding in your vehicle.

(3) Subtract the combined weight of the

driver and passengers from XXX kg or

XXX lbs.

 For the following example, the combined weight

of occupants and cargo should never exceed

865 lbs (392 kg).

(4) The resulting figure equals the

available amount of cargo and luggage

load capacity. For example, if “XXX”

amount equals 1400 lbs. and there will

be five 150 lb passengers in your

vehicle, the amount of available cargo

and luggage load capacity is 650 lbs.

(1400-750 (5x150) = 650 lbs.)

Ride Comfort And Vehicle Stability

WARNING!

Proper tire inflation contributes to a comfortable ride.

Overinflation produces a jarring and uncomfortable ride.

Overloading of your tires is dangerous. Overloading can

cause tire failure, affect vehicle handling, and increase

your stopping distance. Use tires of the recommended

load capacity for your vehicle. Never overload them.

 Overinflated or underinflated tires can affect vehicle

handling and can fail suddenly, resulting in loss of

vehicle control.

Tire Inflation Pressures

The proper cold tire inflation pressure is listed on the

driver's side B-pillar or rear edge of the driver's side door.

 Unequal tirepressures can cause steering problems.

You could lose control of your vehicle.

At least once a month:

TIRES — GENERAL INFORMATION

 Unequal tire pressures from one side of the vehicle

to the other can cause the vehicle to drift to the right

or left.

 Check and adjust tire pressure with a good quality

pocket-type pressure gauge. Do not make a visual

judgment when determining proper inflation.

Tires may look properly inflated even when they are

underinflated.

Tire Pressure

Proper tire inflation pressure is essential to the safe and

satisfactory operation of your vehicle. Four primary areas

are affected by improper tire pressure:

 Always drive with each tire inflated to the recom-

mended cold tire inflation pressure.

 Inspect tires for signs of tire wear or visible damage.

 Safety

Both underinflation and overinflation affect the stability of

the vehicle and can produce a feeling of sluggish response

or over responsiveness in the steering.

 Fuel Economy

 Tread Wear

CAUTION!

After inspecting or adjusting the tire pressure, always

reinstall the valve stem cap. This will prevent moisture

and dirt from entering the valve stem, which could

damage the valve stem.

NOTE:

 Ride Comfort and Vehicle Stability

Safety

 Unequal tire pressures from side to side may cause

erratic and unpredictable steering response.

WARNING!

 Unequal tire pressure from side to side may cause the

vehicle to drift left or right.

8

Inflation pressures specified on the placard are always

“cold tire inflation pressure”. Cold tire inflation pressure is

defined as the tire pressure after the vehicle has not been

driven for at least three hours, or driven less than 1 mile

(1.6 km) after sitting for a minimum of three hours. The

cold tire inflation pressure must not exceed the maximum

inflation pressure molded into the tire sidewall.

 Improperly inflated tires are dangerous and can

cause collisions.

Fuel Economy

Underinflated tires will increase tire rolling resistance

resulting in higher fuel consumption.

 Underinflation increases tire flexing and can result in

overheating and tire failure.

Tread Wear

 Overinflation reduces a tire's abilityto cushion shock.

Objects on the road and chuckholes can cause

damage that result in tire failure.

Improper cold tire inflation pressures can cause abnormal

wear patterns and reduced tread life, resulting in the need

for earlier tire replacement.

(Continued)

378 SERVICING AND MAINTENANCE

Check tire pressures more often if subject to a wide range

of outdoor temperatures, as tire pressures vary with

temperature changes.

Damaged Run Flat tires, or Run Flat tires that have

experienced a loss of pressure should be replaced

immediatelywith another Run Flat tireof identical sizeand

service description (Load Index and Speed Symbol).

Replace the tire pressure sensor as well as it is not

designed to be reused.

WARNING!

High speed driving with your vehicle under maximum

load is dangerous. The added strain on your tires could

cause them to fail. You could have a serious collision.

Do not drive a vehicle loaded to the maximum capacity

at continuous speeds above 75 mph (120 km/h).

Tire pressures change by approximately 1 psi (7 kPa) per

12°F (7°C) of air temperature change. Keep this in mind

when checking tire pressure inside a garage, especially in

the Winter.

Run Flat Tires — If Equipped

Example: If garage temperature = 68°F (20°C) and the

outside temperature = 32°F (0°C) then the cold tire

inflation pressure should be increased by 3 psi (21 kPa),

which equals 1 psi (7 kPa) for every 12°F (7°C) for this

outside temperature condition.

Run Flat tires allow you the capability to drive 50 miles

(80 km) at 50 mph (80 km/h) after a rapid loss of inflation

pressure. This rapid loss of inflation is referred to as the

Run Flat mode. A Run Flat mode occurs when the tire

inflation pressure is of/or below 14 psi (96 kPa).

Once a Run Flat tire reaches the Run Flat mode it has

limited driving capabilities and needs to be replaced

immediately. A Run Flat tire is not repairable. When a Run

Flat tire is changed after being driven in a Run Flat mode

14psi (96 kPa) condition, please replace the TPMS sensor

as it is not designed to be reused.

Radial Ply Tires

WARNING!

Combining radial ply tires with other types of tires on

your vehicle will cause your vehicle to handle poorly.

The instability could cause a collision. Always use radial

ply tires in sets of four. Never combine them with other

types of tires.

Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)

during operation. DO NOT reduce this normal pressure

build up or your tire pressure will be too low.

Tire Pressures For High Speed Operation

The manufacturer advocates driving at safe speeds and

within posted speed limits. Where speed limits or

conditions are such that the vehicle can be driven at high

speeds, maintaining correct tire inflation pressure is very

important. Increased tire pressure and reduced vehicle

loading may be required for high-speed vehicle operation.

Refer to an authorized tire dealer or original equipment

vehicle dealer for recommended safe operating speeds,

loading and cold tire inflation pressures.

Tire Repair

NOTE:

The TPMS Sensor must be replaced after driving the

vehicle on a flat tire condition.

If your tire becomes damaged, it may be repaired if it

meets the following criteria:

It is not recommended driving a vehicle loaded at full

capacity or to tow a trailer while a tire is in the

Run Flat mode.

 The tire has not been driven on when flat

 The damage is only on the tread section of your tire

(sidewall damage is not repairable)

For more information Ú page 277.

 The puncture is no greater than ¼ of an inch (6 mm)

Consult an authorized tire dealer for tire repairs and

additional information.

SERVICING AND MAINTENANCE 379

Tire Spinning

Life Of Tire

When stuck in mud, sand, snow, or ice conditions, do not

spin your vehicle's wheels above 30 mph (48 km/h) or for

longer than 30 seconds continuously without stopping.

The service life of a tire is dependent upon varying factors

including, but not limited to:

 Driving style

For further information Ú page 329.

 Tire pressure - Improper cold tire inflation pressures

can cause uneven wear patterns to develop across the

tire tread. These abnormal wear patterns will reduce

tread life, resulting in the need for earlier tire

replacement

WARNING!

Fast spinning tires can be dangerous. Forces generated

by excessive wheel speeds may cause tire damage or

failure. A tire could explode and injure someone.

Do not spin your vehicle's wheels faster than 30 mph

(48 km/h) for more than 30 seconds continuously

when you are stuck, and do not let anyone near a

spinning wheel, no matter what the speed.

 Distance driven

Tire Tread

1 — Tread Wear Indicators

 Performance tires, tires with a speed rating of V or

higher, and Summer tires typically have a reduced

tread life. Rotation of these tires per the vehicle

scheduled maintenance is highly recommended

These indicators are molded into the bottom of the tread

grooves. They will appear as bands when the tread depth

becomes 1/16 of an inch (1.6 mm). When the tread is

worn to the tread wear indicators, the tire should be

replaced.

WARNING!

Tread Wear Indicators

Tread wear indicators are in the original equipment tires to

help you in determining when your tires should be

replaced.

Tires and the spare tire should be replaced after six

years, regardless of the remaining tread. Failure to

follow this warning can result in sudden tire failure.

You could lose control and have a collision resulting in

serious injury or death.

For further information Ú page 380.

NOTE:

Wheel Valve Stem must be replaced as well when

installing new tires due to wear and tear in existing tires.

Keep dismounted tires in a cool, dry place with as little

exposure to light as possible. Protect tires from contact

with oil, grease, and gasoline.

380 SERVICING AND MAINTENANCE

Replacement Tires

TIRE TYPES

WARNING!

The tires on your new vehicle provide a balance of many

characteristics. They should be inspected regularly for

wear and correct cold tire inflation pressures. The

manufacturer strongly recommends using tires equivalent

to the originals in size, quality and performance when

replacement is needed Ú page 379. Refer to the Tire And

Loading Information Placard or the Vehicle Certification

Label for the size designation of your tire. The Load Index

and Speed Symbol for your tirewill be found on the original

equipment tire sidewall.

All Season Tires — If Equipped

 Do not use a tire, wheel size, load rating, or speed

rating other than that specified for your vehicle.

Some combinations of unapproved tires and wheels

may change suspension dimensions and perfor-

mance characteristics, resulting in changes to

steering, handling, and braking of your vehicle. This

can cause unpredictable handling and stress to

steering and suspension components. You could

lose control and have a collision resulting in serious

injury or death. Use only the tire and wheel sizes with

load ratings approved for your vehicle.

All Season tires provide traction for all seasons (Spring,

Summer, Autumn, and Winter). Traction levels may vary

between different all season tires. All season tires can be

identified by the M+S, M&S, M/S or MS designation on the

tire sidewall. Use all season tires only in sets of four;

failure to do so may adversely affect the safety and

handling of your vehicle.

Summer Or Three Season Tires —

If Equipped

For more information relating totheLoad Index and Speed

Symbol of a tire Ú page 371.

 Never use a tire with a smaller load index or capacity,

other than what was originally equipped on your

vehicle. Using a tire with a smaller load index could

result in tire overloading and failure. You could lose

control and have a collision.

Summer tires provide traction in both wet and dry

conditions, and are notintended tobe driven in snow or on

ice. If your vehicle is equipped with Summer tires, be

aware these tires are not designed for Winter or cold

driving conditions. Install Winter tires on your vehiclewhen

ambient temperatures are less than 40°F (5°C) or if

roads are covered with ice or snow. For more information,

contact an authorized dealer.

It is recommended toreplacethetwo front tires or two rear

tires as a pair. Replacing just one tire can seriously affect

your vehicle’s handling. If you ever replace a wheel, make

sure that the wheel’s specifications match those of the

original wheels.

 Failure to equip your vehicle with tires having

adequate speed capability can result in sudden tire

failure and loss of vehicle control.

It is recommended you contact an authorized tire dealer or

original equipment dealer with any questions you may

have on tire specifications or capability. Failure to use

equivalent replacement tires may adversely affect the

safety, handling, and ride of your vehicle.

Summer tires do not contain the all season designation or

mountain/snowflake symbol on the tire sidewall. Use

Summer tires only in sets of four; failure to do so may

adversely affect the safety and handling of your vehicle.

CAUTION!

Replacing original tires with tires of a different size may

result in false speedometer and odometer readings.

WARNING!

Do not use Summer tires in snow/ice conditions. You

could lose vehicle control, resulting in severe injury or

death. Driving too fast for conditions also creates the

possibility of loss of vehicle control.

SERVICING AND MAINTENANCE 381

Snow Tires

Some areas of the country require the use of snow tires

during the Winter. Snow tires can be identified by a

“mountain/snowflake” symbol on the tire sidewall.

Compact Spare Tire — If Equipped

SPARE TIRES — IF EQUIPPED

The compact spare is for temporary emergency use only.

You can identify if your vehicle is equipped with a compact

spare by looking at the spare tire description on the Tire

And Loading Information Placard located on the driver’s

side door opening or on the sidewall of the tire. Compact

spare tire descriptions begin with the letter “T” or “S”

preceding the size designation. Example: T145/80D18

103M.

NOTE:

For vehicles equipped with Tire Service Kit instead of a

spare tire, please refer to “Tire Service Kit” in “In Case Of

Emergency” for further information.

If you need snow tires, select tires equivalent in

size and type to the original equipment tires.

Use snow tires only in sets of four; failure to do

somay adverselyaffectthe safety and handling

of your vehicle.

CAUTION!

Because of the reduced ground clearance, do not take

your vehicle through an automatic car wash with a

compact or limited use temporary spare installed.

Damage to the vehicle may result.

T, S = Temporary Spare Tire

Snow tires generally have lower speed ratings than what

was originally equipped with your vehicle and should not

be operated at sustained speeds over 75 mph

(120 km/h). For speeds above 75 mph (120 km/h) refer

to original equipment or an authorized tire dealer for

recommended safe operating speeds, loading and cold

tire inflation pressures.

Since this tire has limited tread life, the original equipment

tire should be repaired (or replaced) and reinstalled on

your vehicle at the first opportunity.

For restrictions when towing with a spare tire designated

for temporary emergency use Ú page 179.

Do not install a wheel cover or attempt to mount a

conventional tire on the compact spare wheel, since the

wheel is designed specifically for the compact spare tire.

Do not install more than onecompact spare tireand wheel

on the vehicle at any given time.

Spare Tire Matching Original Equipped Tire

And Wheel — If Equipped

While studded tires improve performance on ice, skid and

traction capability on wet or dry surfaces may be poorer

than that of non-studded tires. Some states prohibit

studded tires; therefore, local laws should be checked

before using these tire types.

Your vehicle may be equipped with a spare tire and wheel

equivalent in look and function to the original equipment

tire and wheel found on the front or rear axle of your

vehicle. This spare tire may be used in the tire rotation for

your vehicle. If your vehicle has this option, refer to an

authorized tire dealer for the recommended tire rotation

pattern.

WARNING!

NOTE:

WHEEL AND WHEEL TRIM CARE

CAUTION!

If you intend parking or storing your vehicle for an

extended period after cleaning the wheels with wheel

cleaner, drive your vehicle and apply the brakes to remove

the water droplets from the brake components. This

activity will remove the red rust on the brake rotors and

prevent vehicle vibration when braking.

All wheels and wheel trim, especially aluminum and

chrome plated wheels, should be cleaned regularly using

mild (neutral Ph) soap and water to maintain their luster

and to prevent corrosion. Wash wheels with the same

soap solution recommended for the body of the vehicle

and remember to always wash when the surfaces are not

hot to the touch.

Avoid products or automatic car washes that use acidic

solutions or strong alkaline additives or harsh brushes.

Many aftermarket wheel cleaners and automatic car

washes may damage the wheel's protective finish. Such

damage is not covered by the New Vehicle Limited

Warranty. Only car wash soap, Mopar® Wheel Cleaner

or equivalent is recommended.

Dark Vapor Chrome, Black Satin Chrome, or Low Gloss

Clear Coat Wheels

Your wheels are susceptible to deterioration caused by

salt, sodium chloride, magnesium chloride, calcium

chloride, etc., and other road chemicals used to melt ice

or control dust on dirt roads. Use a soft cloth or sponge

and mild soap to wipe away promptly. Do not use harsh

chemicals or a stiff brush. They can damage the wheel’s

protective coating that helps keep them from corroding

and tarnishing.

CAUTION!

When cleaning extremely dirty wheels including excessive

brake dust, care must be taken in the selection of tire and

wheel cleaning chemicals and equipment to prevent

damage to the wheels. Mopar® Wheel Treatment or

Mopar® Chrome Cleaner or their equivalent is

recommended or select a non-abrasive, non-acidic

cleaner for aluminum or chrome wheels.

If your vehicle is equipped with these specialty wheels,

DO NOT USE wheel cleaners, abrasives, or polishing

compounds. They will permanently damage this finish

and such damage is not covered by the New Vehicle

Limited Warranty. HAND WASH ONLY USING MILD SOAP

AND WATER WITH A SOFT CLOTH. Used on a regular

basis; this is all that is required to maintain this finish.

CAUTION!

Do not use scouring pads, steel wool, a bristle brush,

metal polishes or oven cleaner. These products may

damage the wheel's protective finish. Such damage is

not covered by the New Vehicle Limited Warranty. Only

car wash soap, Mopar® Wheel Cleaner or equivalent is

recommended.

TIRE ROTATION RECOMMENDATIONS

DEPARTMENT OF TRANSPORTATION

UNIFORM TIRE QUALITY GRADES

Tires on the front and rear axles of vehicles operate at

different loads and perform different steering, driving, and

braking functions. For these reasons, they wear at

unequal rates.

To avoid damage to your vehicle or tires, observe the

following precautions:

The following tire grading categories

were established by the National

Highway Traffic Safety Administration.

The specific grade rating assigned by the

tire's manufacturer in each category is

shown on the sidewall of the tires on

your vehicle.

 Because of restricted traction device clearance

between tires and other suspension components, it is

important that only traction devices in good condition

are used. Broken devices can cause serious damage.

Stop the vehicle immediately if noise occurs that could

indicate device breakage. Remove the damaged parts

of the device before further use.

These effects can be reduced by timely rotation of tires.

The benefits of rotation are especially worthwhile with

aggressive tread designs such as those on all season type

tires. Rotation will increase tread life, help to maintain

mud, snow and wet traction levels and contribute to a

smooth, quiet ride.

 Install device as tightly as possible and then retighten

after driving about ½ mile (0.8 km). Autosock traction

devices do not require retightening.

For the proper maintenance intervals Ú page 334. More

frequent rotation is permissible if desired. The reasons for

any rapid or unusual wear should be corrected prior to

rotation being performed.

All passenger vehicle tires must conform

to Federal safety requirements in

addition to these grades.

 Do not exceed 30 mph (48 km/h).

The suggested rotation method is the “rearward cross”

shown in the following diagram. This rotation pattern does

not apply to some directional tires that must not be

reversed.

 Drive cautiously and avoid severe turns and large

bumps, especially with a loaded vehicle.

TREADWEAR

 Do not drive for a prolonged period on dry pavement.

The Treadwear grade is a comparative

rating, based on the wear rate of the tire

when tested under controlled conditions

on a specified government test course.

For example, a tire graded 150 would

wear one and one-half times as well on

the government course as a tire

graded 100.

 Observe the traction device manufacturer’s instruc-

tions on the method of installation, operating speed,

and conditions for use. Always use the suggested oper-

ating speed of the device manufacturer’s if it is less

than 30 mph (48 km/h).

 Do not use traction devices on a compact spare tire.

SERVICING AND MAINTENANCE 387

WARNING!

The relative performance of tires

depends upon the actual conditions of

their use, however, and may depart

significantly from the norm due to

variations in driving habits, service

practices, and differences in road

characteristics and climate.

TEMPERATURE GRADES

The Temperature grades are A (the

highest), B, and C, representing the tire's

resistance to the generation of heat and

its ability to dissipate heat, when tested

specified indoor laboratory test wheel.

STORING THE VEHICLE

TRACTION GRADES

If you are storing your vehicle for more than three weeks,

we recommend that you take the following steps to

minimize the drain on your vehicle's battery:

Sustained high temperature can cause

the material of the tire to degenerate

and reduce tire life, and excessive

temperature can lead to sudden tire

failure. The grade C corresponds to a

level of performance, which all

passenger vehicle tires must meet

under the Federal Motor Vehicle Safety

Standard No. 109. Grades B and A

represent higher levels of performance

on the laboratory test wheel, than the

minimum required by law.

The Traction grades, from highest to

lowest, are AA, A, B, and C. These grades

represent the tire's ability to stop on wet

pavement, as measured under

controlled conditions on specified

government test surfaces of asphalt and

concrete. A tire marked C may have poor

traction performance.

 Disconnect the negative cable from battery.

 Any time you store your vehicle or keep it out of service

(i.e., vacation) for two weeks or more, run the air condi-

tioning system at idle for about five minutes in the

fresh air and high blower setting. This will ensure

adequate system lubrication to minimize the

possibility of compressor damage when the system

is started again.

WARNING!

The traction grade assigned to this tire is based on

straight-ahead braking traction tests, and does not

include acceleration, cornering, hydroplaning, or peak

traction characteristics.

388 SERVICING AND MAINTENANCE

 Use a high quality cleaner wax, such as Mopar®

Cleaner Wax to remove road film, stains and to protect

your paint finish. Use precautions to not scratch the

paint.

BODY AND UNDERBODY MAINTENANCE

BODYWORK

PROTECTION FROM ATMOSPHERIC

AGENTS

Vehicle body care requirements vary according to

geographic locations and usage. Chemicals that make

roads passable in snow and ice and those that are

sprayed on trees and road surfaces during other seasons

are highly corrosive to the metal in your vehicle. Outside

parking, which exposes your vehicle to airborne

contaminants, road surfaces on which the vehicle is

operated, extreme hot or cold weather and other extreme

conditions will have an adverse effect on paint, metal trim,

and underbody protection.

Cleaning Headlights

Your vehicle is equipped with plastic headlights and fog

lights that are lighter and less susceptible to stone

breakage than glass headlights.

 Avoid using abrasive compounds and power buffing

that may diminish the gloss or thin out the paint finish.

Plastic is not as scratch resistant as glass and therefore

different lens cleaning procedures must be followed.

CAUTION!

 Do not use abrasive or strong cleaning materials

such as steel wool or scouring powder that will

scratch metal and painted surfaces.

To minimize the possibility of scratching the lenses and

reducing light output, avoid wiping with a dry cloth.

To remove road dirt, wash with a mild soap solution

followed by rinsing.

 Use of power washers exceeding 1,200 psi

(8,274 kPa) can result in damage or removal of paint

and decals.

Do not use abrasive cleaning components, solvents, steel

wool or other aggressive material to clean the lenses.

Tri-Fold Soft Tonneau Cover Care

For cleaning and protecting the vinyl Tri-Fold Tonneau

cover, use Mopar® Whitewall & Vinyl Top Cleaner and

Mopar® Leather and Vinyl Conditioner/Protectant.

The following maintenance recommendations will enable

you to obtain maximum benefit from the corrosion

resistance built into your vehicle.

Fascia/Bumper Care

The customer is responsible to clean and maintain

the chrome components of the vehicle. Wash away

road debris and salt using an automotive soap.

Fascia/bumpers should be cleaned regularly using mild

(neutral Ph) soap and water to maintain their luster and to

prevent corrosion.

What Causes Corrosion?

Corrosion is the result of deterioration or removal of paint

and protective coatings from your vehicle.

PRESERVING THE BODYWORK

Washing

The most common causes are:

 Wash your vehicle regularly. Always wash your vehicle

in the shade using Mopar® Car Wash, or a mild car

wash soap, and rinse the panels completely with water.

 Road salt, dirt and moisture accumulation.

 Stone and gravel impact.

Your fascia/bumpers are susceptible to deterioration

caused by salt, sodium chloride, magnesium chloride,

calcium chloride, etc., and other road chemicals used to

melt ice or control dust on dirt roads. Do not use harsh

chemicals or a stiff brush. They can stain or damage the

protective coating that helps keep them from corroding

and tarnishing.

 Insects, tree sap and tar.

 If insects, tar, or other similar deposits have accumu-

lated on your vehicle, use Mopar® Super Kleen Bug

and Tar Remover to remove.

 Salt in the air near seacoast localities.

 Atmospheric fallout/industrial pollutants.

SERVICING AND MAINTENANCE 389

 If you carry special cargo such as chemicals, fertilizers,

de-icer salt, etc., be sure that such materials are well

packaged and sealed.

4. Once dry, apply a small amount of Mopar® Spray-On

Bedliner Conditioner to a moist towel or sponge and

wipe over the entire surface of the truck bedliner.

CAUTION!

 Do not use scouring pads, steel wool, a bristle brush,

metal polishes, or oven cleaner. These products may

damage the bumper’s protective finish. Such

damage is not covered by the New Vehicle Limited

Warranty. Only car wash soap, Mopar® Chrome

Cleaner, or equivalent is recommended.

 If a lot of driving is done on gravel roads, consider mud

or stone shields behind each wheel.

WARNING!

 Use Mopar® Touch Up Paint on scratches as soon as

possible. An authorized dealer has touch up paint to

match the color of your vehicle.

Do not use silicon-based protection products to clean

your bedliner. Silicon-based products can become

slippery and may result in personal injury.

 Avoid products or automatic car washes that use

acidic solutions, strong alkaline additives, or harsh

brushes. Many aftermarket cleaners and automatic

car washes may damage the bumper’s protective

finish. Such damage is not covered by the New

Vehicle Limited Warranty. Only car wash soap,

Mopar® Chrome Cleaner, or equivalent is

recommended.

Spray-On Bedliner – If Equipped

Spray-On Bedliners are chemically-resistant to many

different types of chemicals (including gasoline, oil,

hydraulic fluids) for short periods of time. If a spill occurs

on your Spray-On Bedliner, rinse the truck out as soon as

possible to avoid permanent damage.

During ownership, the shine and luster of the Spray-On

Bedliner can fade from oxidation, road dirt, heavy-duty

hauling and hard water stains. Weathering and UV

exposure will lead to fading.

To help maintain the appearance of your Spray-On

Bedliner, the manufacturer recommends you periodically

rinse all loosedirtfrom your truck bed and clean your truck

at least twice per year using the Mopar® Spray-On

Bedliner Conditioner available at a local authorized

dealer.

Repairing The Spray-On Bedliner

While extremely tough, it is possible to damage a Spray-On

Bedliner. One common condition is when loading a heavy

pallet and dragging that pallet across the floor of the bed.

If a nail or sharp point is exposed under the weight of the

pallet a scratch or tear is possible. While not covered by

your new vehicle warranty, a cosmetic fix to cover the

metal exposed by the scratch is required. To repair a tear

or gouge, follow the directions provided in the Mopar®

Quick Repair Kit.

Special Care

 If you drive on salted or dusty roads or if you drive near

the ocean, hose off the undercarriage at least once a

month.
