Impaired Driving

Death and injury associated with impaired

driving is a global tragedy.

To avoid distracted driving, keep your eyes

on the road, keep your hands on the

steering wheel, and focus your attention on

driving.

Driving and Operating

Electric Power Steering

Control of a Vehicle

Steering

The vehicle is equipped with an electric

power steering system, which reduces the

amount of effort needed to steer the

vehicle. It does not have power steering

fluid. Regular maintenance is not required.

Braking, steering, and accelerating are

important factors in helping to control a

vehicle while driving.

Caution

To avoid damage to the steering system,

do not drive over curbs, parking barriers,

or similar objects at speeds greater than

3 km/h (1 mph). Use care when driving

over other objects such as lane dividers

and speed bumps. Damage caused by

misuse of the vehicle is not covered by

the vehicle warranty.

Braking

If the vehicle experiences a system

malfunction and loses power steering,

greater steering effort may be required.

Power steering assist also may be reduced if

you turn the steering wheel as far as it can

turn and hold it there with force for an

extended period of time.

Braking action involves perception time and

reaction time. Deciding to push the brake

pedal is perception time. Actually doing it is

reaction time.

Average driver reaction time is about

three-quarters of a second. In that time, a

vehicle moving at 100 km/h (60 mph) travels

20 m (66 ft), which could be a lot of

distance in an emergency.

See your dealer if there is a problem.

Curve Tips

Helpful braking tips to keep in mind include:

.

Take curves at a reasonable speed.

Reduce speed before entering a curve.

Maintain a reasonable steady speed

through the curve.

.

Keep enough distance between you and

the vehicle in front of you.

.

Avoid needless heavy braking.

Keep pace with traffic.

.

Wait until the vehicle is out of the curve

before accelerating gently into the

straightaway.

If the engine ever stops or a brake fault

occurs, the brakes may lose power assist.

More effort will be required to stop the

vehicle. It may take longer to stop.

Steering in Emergencies

.

There are some situations when steering

around a problem may be more effective

than braking.

Driving and Operating

197

.

Slow down and adjust your driving

Holding both sides of the steering wheel

allows you to turn 180 degrees without

removing a hand.

The Antilock Brake System (ABS) allows

steering while braking.

2. Turn the steering wheel about

one-eighth of a turn, until the right front

tire contacts the pavement edge.

according to weather conditions. Stopping

distance can be longer and vehicle control

can be affected when traction is reduced

by water, snow, ice, gravel, or other

material on the road. Learn to recognize

warning clues — such as enough water,

ice, or packed snow on the road to make

a mirrored surface — and slow down

when you have any doubt.

3. Turn the steering wheel to go straight

down the roadway.

Off-Road Recovery

Loss of Control

Skidding

There are three types of skids that

correspond to the vehicle's three control

systems:

.

Try to avoid sudden steering, acceleration,

or braking, including reducing vehicle

speed by shifting to a lower gear. Any

sudden changes could cause the tires to

slide.

.

Braking Skid — wheels are not rolling.

.

Steering or Cornering Skid — too much

speed or steering in a curve causes tires

to slip and lose cornering force.

Remember: Antilock brakes help avoid only

the braking skid.

.

Acceleration Skid — too much throttle

causes the driving wheels to spin.

Off-Road Driving

Defensive drivers avoid most skids by taking

reasonable care suited to existing conditions,

and by not overdriving those conditions. But

skids are always possible.

Four-wheel-drive vehicles can be used for

off-road driving. Vehicles without four-wheel

drive and vehicles not equipped with All

Terrain (AT) or On-Off Road (OOR) tires must

not be driven off-road except on a level,

solid surface. For contact information about

the original equipment tires, see the

warranty manual.

The vehicle's right wheels can drop off the

edge of a road onto the shoulder while

driving. Follow these tips:

1. Ease off the accelerator and then,

if there is nothing in the way, steer the

vehicle so that it straddles the edge of

the pavement.

If the vehicle starts to slide, follow these

suggestions:

Ease your foot off the accelerator pedal

and steer the way you want the vehicle

to go. The vehicle may straighten out. Be

ready for a second skid if it occurs.

.

One of the best ways for successful off-road

driving is to control the speed.

Driving and Operating

For more information about loading the

vehicle, see Vehicle Load Limits 0 204 and

Tires 0 369.

Caution

Warning

{

Operating the vehicle for extended

periods without the front fascia lower air

dam installed can cause improper airflow

to the engine. Reattach the front fascia

air dam after off-road driving.

When driving off-road, bouncing and

quick changes in direction can easily

throw you out of position. This could

cause you to lose control and crash. You

and your passengers should always wear

seat belts.

Environmental Concerns

.

Always use established trails, roads, and

areas that have been set aside for public

off-road recreational driving and obey all

posted regulations.

Loading the Vehicle for Off-Road Driving

.

Do not damage shrubs, flowers, trees,

or grasses or disturb wildlife.

Do not park over things that burn. See

Before Driving Off-Road

Have all necessary maintenance and

service work completed.

Fuel the vehicle, fill fluid levels, and check

inflation pressure in all tires, including the

spare, if equipped.

Warning

{

.

Unsecured cargo on the load floor can

be tossed about when driving over

rough terrain. You or your passengers

can be struck by flying objects. Secure

the cargo properly.

Parking over Things That Burn 0 219.

Driving on Hills

Driving safely on hills requires good

judgment and an understanding of what the

vehicle can and cannot do.

.

Read all the information about

four-wheel-drive vehicles in this manual.

.

Keep cargo in the cargo area as far

forward and as low as possible. The

heaviest things should be on the floor,

forward of the rear axle.

Remove any underbody air deflector,

if equipped. Re-attach the air deflector

after off-road driving.

Know the local laws that apply to off-road

driving.

Warning

{

Many hills are simply too steep for any

vehicle. Driving up hills can cause the

vehicle to stall. Driving down hills can

cause loss of control. Driving across hills

can cause a rollover. You could be injured

or killed. Do not drive on steep hills.

Heavy loads on the roof raise the

vehicle's center of gravity, making it

more likely to roll over. You can be

seriously or fatally injured if the

vehicle rolls over. Put heavy loads

inside the cargo area, not on the roof.

.

To gain more ground clearance if needed, it

may be necessary to remove the front fascia

lower air dam, if equipped. However, driving

without the air dam reduces fuel economy.

Driving and Operating

199

.

Avoid turns that take the vehicle across

the incline of the hill. Driving across an

incline puts more weight on the downhill

wheels, which could cause a downhill

slide or a rollover.

Loose gravel, muddy spots, or even wet

grass can cause the tires to slip sideways,

downhill. If the vehicle slips sideways, it

can hit something and potentially

roll over.

Hidden obstacles can make the steepness

of the incline more severe. If a rock is

driven across with the uphill wheels, or if

the downhill wheels drop into a rut or

depression, the vehicle can tilt even more.

Before driving on a hill, assess the

steepness, traction, and obstructions. If the

terrain ahead cannot be seen, get out of the

vehicle and walk the hill before driving

further.

Warning

{

If the vehicle has the two-speed

automatic transfer case, shifting the

transfer case to N (Neutral) can cause

your vehicle to roll even if the

transmission is in P (Park). This is because

the N (Neutral) position on the transfer

case overrides the transmission. You or

someone else could be injured. If leaving

the vehicle, set the parking brake and

shift the transmission to P (Park). Shift

the transfer case to any position but

N (Neutral).

When driving on hills:

.

Use a low gear and keep a firm grip on

the steering wheel.

.

Maintain a slow speed.

When possible, drive straight up or down

the hill.

.

Slow down when approaching the top of

the hill.

Warning

{

.

If an incline must be driven across, and

the vehicle starts to slide, turn downhill.

This should help straighten out the

vehicle and prevent the side slipping.

Never go downhill forward or backward

with either the transmission or transfer

case in N (Neutral). The brakes could

overheat and you could lose control.

When driving down a hill, keep the

vehicle headed straight down. Use a low

gear because the engine will work with

the brakes to slow the vehicle and help

keep the vehicle under control.

Driving to the top of a hill at high speed

can cause a crash. There could be a

drop-off, embankment, cliff, or even

another vehicle. You could be seriously

injured or killed. As you near the top of a

hill, slow down and stay alert.

Warning

{

Heavy braking when going down a hill

can cause your brakes to overheat and

fade. This could cause loss of control and

you or others could be injured or killed.

Apply the brakes lightly when descending

a hill and use a low gear to keep vehicle

speed under control.

.

Use headlamps even during the day to

make the vehicle more visible.

If a brake fade condition is detected, a DIC

warning message is displayed. Adjust brake

pedal use and shift to a lower transmission

gear to reduce braking.

200

Driving and Operating

.

If driving downhill when the vehicle

stalls, shift to a lower gear, release

the parking brake, and drive straight

down the hill.

If the brakes continue to fade to a severe

condition, additional DIC messages are

displayed. The brake system warning light

will illuminate, and the vehicle speed may

be limited. See Brake System Warning Light

0 119.

This affects steering, accelerating, and

braking. Drive at a reduced speed and avoid

sharp turns or abrupt maneuvers.

Traction is reduced on hard packed snow

and ice and it is easy to lose control. Reduce

vehicle speed when driving on hard packed

snow and ice.

3. If the vehicle cannot be restarted after

stalling, set the parking brake, shift into

P (Park), and turn the vehicle off.

If the vehicle stalls on a hill:

3.1. Leave the vehicle and seek help.

1. Apply the brakes to stop the vehicle, and

then apply the parking brake.

Warning

{

3.2. Stay clear of the path the vehicle

would take if it rolled downhill.

Driving on frozen lakes, ponds, or rivers

can be dangerous. Ice conditions vary

greatly and the vehicle could fall through

the ice; you and your passengers could

drown. Drive your vehicle on safe

surfaces only.

2. Shift into P (Park) and then restart the

engine.

Warning

If driving uphill when the vehicle

stalls, shift to R (Reverse), release the

parking brake, and back

Getting out of the vehicle on the

downhill side when stopped across an

incline is dangerous. If the vehicle rolls

over, you could be crushed or killed.

Always get out on the uphill side of the

vehicle and stay well clear of the

rollover path.

straight down.

.

Never try to turn the vehicle around.

If the hill is steep enough to stall the

vehicle, it is steep enough to cause it

to roll over.

Driving in Water

Warning

{

.

If you cannot make it up the hill,

back straight down the hill.

Never back down a hill in N (Neutral)

using only the brake. The vehicle can

roll backward quickly and you could

lose control.

Driving through rushing water can be

dangerous. Deep water can sweep your

vehicle downstream and you and your

passengers could drown. If it is only

shallow water, it can still wash away the

ground from under your tires. Traction

could be lost, and the vehicle could roll

over. Do not drive through rushing water.

Driving in Mud, Sand, Snow, or Ice

Use a low gear when driving in mud — the

deeper the mud, the lower the gear. Keep

the vehicle moving to avoid getting stuck.

Traction changes when driving on sand. On

loose sand, such as on beaches or sand

dunes, the tires tend to sink into the sand.

exhaust system for damage and check the

fuel lines and cooling system for any

leakage.

Caution

Do not drive through standing water if it

is deep enough to cover the wheel hubs,

axles, or exhaust pipe. Deep water can

damage the axle and other vehicle parts.

Flowing or rushing water creates strong

forces. Driving through flowing water

could cause the vehicle to be carried

away. If this happens, you and other

vehicle occupants could drown. Do not

ignore police warnings and be very

cautious about trying to drive through

flowing water.

More frequent maintenance service is

required. See the Maintenance Schedule

0 417.

If the standing water is not too deep, drive

through it slowly. At faster speeds, water

can get into the engine and cause it to stall.

Stalling can occur if the exhaust pipe is

under water. Do not turn off the ignition

when driving through water. If the exhaust

pipe is under water, the engine will not

start. When going through water, the brakes

get wet and it may take longer to stop. See

“Driving on Wet Roads” later in this section.

Driving on Wet Roads

Rain and wet roads can reduce vehicle

traction and affect your ability to stop and

accelerate. Always drive slower in these

types of driving conditions and avoid driving

through large puddles and deep-standing or

flowing water.

Hydroplaning

Hydroplaning is dangerous. Water can build

up under the vehicle's tires so they actually

ride on the water. This can happen if the

road is wet enough and you are going fast

enough. When the vehicle is hydroplaning, it

has little or no contact with the road.

Warning

{

Wet brakes can cause crashes. They

might not work as well in a quick stop

and could cause pulling to one side. You

could lose control of the vehicle.

After Off-Road Driving

Remove any brush or debris that has

collected on the underbody or chassis,

or under the hood. These accumulations can

be a fire hazard. Reinstall underbody air

deflector and air dam if removed.

There is no hard and fast rule about

hydroplaning. The best advice is to slow

down when the road is wet.

After driving through a large puddle of

water or a car/vehicle wash, lightly apply

the brake pedal until the brakes work

normally.

Other Rainy Weather Tips

After operation in mud or sand, have the

brake linings cleaned and checked. These

substances can cause glazing and uneven

braking. Check the body structure, driveline,

steering, suspension, wheels, tires, and

Besides slowing down, other wet weather

driving tips include:

(Continued)

Driving and Operating

.

Keep windshield wiping equipment in

good shape.

Keep the windshield washer fluid reservoir

filled.

Have good tires with proper tread depth.

See Tires 0 369.

Snow or ice between the tires and the road

creates less traction or grip, so drive

carefully. Wet ice can occur at about 0 °C

(32 °F) when freezing rain begins to fall.

Avoid driving on wet ice or in freezing rain

until roads can be treated.

Warning

{

Coasting downhill in N (Neutral) or with

the ignition off is dangerous. This can

cause overheating of the brakes and loss

of steering assist. Always have the engine

running and the vehicle in gear.

For Slippery Road Driving:

Turn off cruise control.

.

Accelerate gently. Accelerating too quickly

causes the wheels to spin and makes the

surface under the tires slick.

Turn on Traction Control. See Traction

Control/Electronic Stability Control 0 237.

.

Drive at speeds that keep the vehicle in

its own lane. Do not swing wide or cross

the center line.

Be alert on top of hills; something could

be in your lane (e.g., stalled car, crash).

Pay attention to special road signs (e.g.,

falling rocks area, winding roads, long

grades, passing or no-passing zones) and

take appropriate action.

Hill and Mountain Roads

Driving on steep hills or through mountains

is different than driving on flat or rolling

terrain. Tips include:

.

The Antilock Brake System (ABS) improves

vehicle stability during hard stops, but

the brakes should be applied sooner than

when on dry pavement. See Antilock

Brake System (ABS) 0 235.

Allow greater following distance and

watch for slippery spots. Icy patches can

occur on otherwise clear roads in shaded

areas. The surface of a curve or an

overpass can remain icy when the

surrounding roads are clear. Avoid sudden

steering maneuvers and braking while

on ice.

Keep the vehicle serviced and in good

shape.

.

Check all fluid levels and brakes, tires, and

cooling system.

Shift to a lower gear when going down

steep or long hills.

transmission shift patterns, and cabin fan

speed may operate differently to enable the

vehicle to warm up quicker. You can

manually override the cabin fan speed in

cold weather mode.

If the vehicle is stuck in snow:

.

Clear snow from the base of the

vehicle, especially any blocking the

exhaust pipe.

If the Vehicle Is Stuck

Slowly and cautiously spin the wheels to

free the vehicle when stuck in sand, mud,

ice, or snow. See “Rocking the Vehicle to Get

It Out” later in this section.

.

Open a window about 5 cm (2 in) on

the vehicle side that is away from the

wind, to bring in fresh air.

If equipped, the front and rear axles may be

locked to improve traction. See Locking Front

Axle 0 245 and Locking Rear Axle 0 244.

Driving and Operating

For information about using tire chains on

the vehicle, see Tire Chains 0 387.

If equipped, there are recovery hooks at the

front of the vehicle. Use them if the vehicle

is stuck off-road and needs to be pulled

some place to continue driving.

Recovery Hooks

Warning

Rocking the Vehicle to Get It Out

Never pull on recovery hooks from the

side. The hooks could break and you and

others could be injured. When using

recovery hooks, always pull the vehicle

from the front.

Caution

Vehicle Load Limits

Do not hold the steering wheel at full

rotation for more than 15 seconds and/or

at an elevated RPM. Damage may occur

to the power steering system and there

may be loss of power steering assist.

It is very important to know how much

weight the vehicle can carry. This

weight is called the vehicle capacity

weight and includes the weight of all

occupants, cargo, and all

nonfactory-installed options. Two labels

on the vehicle may show how much

weight it was designed to carry: the

Tire and Loading Information label and

the Certification/Tire label.

Turn the steering wheel left and right to

clear the area around the front wheels. Then

make sure the wheels are pointed straight

ahead. For four-wheel-drive vehicles, shift

into Four-Wheel Drive High. Turn the TCS

off. Shift back and forth between R (Reverse)

and a forward gear, spinning the wheels as

little as possible. To prevent transmission

wear, wait until the wheels stop spinning

before shifting gears. Slowly spinning the

wheels in the forward and reverse directions

causes a rocking motion that could free the

vehicle. If that does not get the vehicle out

after a few tries, it might need to be towed

out. See Transporting a Disabled Vehicle

0 402. Recovery hooks can be used, if the

vehicle has them.

Warning

{

Do not load the vehicle any heavier

than the Gross Vehicle Weight Rating

(GVWR), or either the maximum

front or rear Gross Axle Weight

Rating (GAWR). This can cause

systems to break and change the

way the vehicle handles. This could

cause loss of control and a crash.

weigh the vehicle before buying and

installing the new equipment.

Loading Points

When using this upper load platform,

be sure the load is securely tied down

to prevent it from shifting. The load's

center of gravity should be positioned

in a zone over the rear axle. The zone is

located in the area between the front

of each wheel well and the rear of each

wheel well. The center of gravity height

must not extend above the top of the

Driving and Operating

Caution (Continued)

The vehicle has a shift stabilization feature

that adjusts the transmission shifting to the

current driving conditions in order to reduce

rapid upshifts and downshifts. This shift

stabilization feature is designed to

determine, before making an upshift, if the

engine is able to maintain vehicle speed by

analyzing things such as vehicle speed,

throttle position, and vehicle load. If the

shift stabilization feature determines that a

current vehicle speed cannot be maintained,

the transmission does not upshift and

instead holds the current gear. In some

cases, this could appear to be a delayed

shift, however the transmission is operating

normally.

Driving and Operating

227

When the shift lever is moved from

D (Drive) to L (Manual Mode), a number

displays next to the L, indicating the current

transmission range.

In vehicles with gasoline engines, when the

shift lever is moved from D (Drive) to

L (Manual Mode), a downshift may occur.

The gear that the transmission is operating

in when the shift lever is moved from D

(Drive) to L (Manual Mode) determines if a

downshift occurs. See the following charts.

Manual Mode (Mechanical

Shifter)

Range Selection Mode

This number is the highest gear that the

transmission will allow while operating in

L (Manual Mode). All gears below that

number are available. As driving conditions

change, the transmission can automatically

shift to lower gears. For example, when L5 is

selected, 1 (First) through 5 (Fifth) gears are

automatically shifted by the transmission,

but 6 (Sixth) cannot be used until the plus/

minus button on the shift lever is used to

change to the range.

Range Selection Mode helps control the

vehicle transmission and vehicle speed while

driving downhill or towing a trailer.

It permits the manual selection of a desired

gear range.

To use this feature:

1. Move the shift lever to L (Manual Mode).

2. Press the plus/minus buttons on the

To apply the EPB:

The vehicle may automatically apply the EPB

in some situations when the vehicle is not

moving. This is normal, and is done to

periodically check the correct operation of

the EPB system, or at the request of other

safety functions that utilize the EPB.

1. Be sure the vehicle is at a complete stop.

2. Press the EPB switch momentarily.

The red parking brake status light will flash

and then stay on once the EPB is fully

applied. If the red parking brake status light

flashes continuously, then the EPB is only

partially applied or there is a problem with

the EPB. A DIC message will display. Release

the EPB and try to apply it again. If the

light does not come on, or keeps flashing,

have the vehicle serviced. Do not drive the

vehicle if the red parking brake status light

is flashing. See your dealer.

If the EPB fails to apply, block the rear

wheels to prevent vehicle movement.

System Operation

Automatic EPB Release

The vehicle has a Traction Control System

(TCS) and StabiliTrak/Electronic Stability

Control (ESC), an electronic stability control

system. These systems help limit wheel spin

and assist the driver in maintaining control,

especially on slippery road conditions.

The EPB will automatically release if the

vehicle is running, placed into gear, and an

attempt is made to drive away. Avoid rapid

acceleration when the EPB is applied, to

preserve parking brake lining life.

When the vehicle is stopped on a grade, Hill

Start Assist (HSA) prevents the vehicle from

rolling in an unintended direction during the

transition from brake pedal release to

accelerator pedal apply. The brakes release

when the accelerator pedal is applied. If the

accelerator pedal is not applied within a few

minutes, the Electric Parking Brake will

apply. The brakes may also release under

other conditions. Do not rely on HSA to hold

the vehicle.

TCS activates if it senses that any of the

drive wheels are spinning or beginning to

lose traction. When this happens, TCS

applies the brakes to the spinning wheels

and reduces engine power to limit

wheel spin.

Brake Assist

Brake Assist detects rapid brake pedal

applications due to emergency braking

situations and provides additional braking to

activate the Antilock Brake System (ABS) if

the brake pedal is not pushed hard enough

to activate ABS normally. Minor noise, brake

pedal pulsation, and/or pedal movement

during this time may occur. Continue to

pedestrian directly ahead, and the brakes

have not been applied, FPB may

automatically brake moderately or brake

hard. This can help to avoid some very low

speed pedestrian crashes or reduce

pedestrian injury. FPB can automatically

brake to detected pedestrians between

8 km/h (5 mph) and 80 km/h (50 mph).

Automatic braking levels may be reduced

under certain conditions, such as higher

speeds.

Automatic Braking can be disabled through

vehicle personalization. To view available

settings from the infotainment screen, touch

Settings > Vehicle > Collision/Detection

Systems > Front Pedestrian Detection.

Warning

{

Using the Front Pedestrian Braking

system while towing a trailer could cause

you to lose control of the vehicle and

crash. Turn the system to Alert or Off

when towing a trailer.

FPB may slow the vehicle to a complete

stop to try and avoid a potential collision

with a pedestrian. If this happens, Automatic

Braking may hold the vehicle at a stop

momentarily. Firmly press the accelerator

pedal to release Automatic Braking.

Without Head-Up Display

When the vehicle approaches a pedestrian

ahead too rapidly, the red FPB alert display

will flash on the windshield. Eight rapid

high-pitched beeps will sound from the

front, or both sides of the Safety Alert Seat

will pulse five times. When this Pedestrian

Alert occurs, the brake system may prepare

for driver braking to occur more rapidly

which can cause a brief, mild deceleration.

Cleaning the System

If FPB does not seem to operate properly,

cleaning the outside of the windshield in

front of the rearview mirror may correct the

issue.

Trailering is different than just driving the

vehicle by itself. Trailering affects the

handling, acceleration, braking, and

durability of your vehicle. Successful, safe

trailering takes correct equipment, and it

has to be used properly.

Maintenance when Trailer Towing

The vehicle needs service more often when

used to tow trailers. See Maintenance

Schedule 0 417. It is especially important to

check the engine oil, axle lubricant, belts,

cooling system, and brake system before

and during each trip.

When towing a trailer, the combined weight

of the vehicle, vehicle contents, trailer, and

trailer contents must be below all of the

maximum weight ratings for the vehicle,

including:

towing a trailer with the vehicle.

304

Driving and Operating

A trailering information label on the B-pillar

shows tow rating information for the

vehicle.

To check that the weight of the vehicle and

trailer are within the GCWR for the vehicle,

follow these steps:

1. Start with the "curb weight" from the

Trailering Information Label.

Warning

{

You and others could be seriously injured

or killed if the trailer is too heavy or the

trailer brakes are inadequate for the load.

The vehicle may be damaged, and the

repairs would not be covered by the

vehicle warranty.

2. Add the weight of the trailer loaded with

cargo and ready for the trip.

3. Add the weight of all passengers.

4. Add the weight of all cargo in the

vehicle.

5. Add the weight of hitch hardware such

as a draw bar, ball, load equalizer bars,

or sway bars.

Only tow a trailer if all the steps in this

section have been followed. Ask your

dealer for advice and information about

towing a trailer.

Gross Combined Weight (GCW) Alert

If equipped, the GCW Alert can display a

message in the Driver Information Center

(DIC), indicating that the estimated

combined weight of the vehicle and trailer

may exceed the vehicle’s GCWR, under

certain circumstances. See “Gross Combined

Weight Rating” above. The vehicle does not

actually measure the loaded weight of your

vehicle or trailer. It uses vehicle data to

estimate these weights after you begin

a trip.

6. Add the weight of any accessories or

aftermarket equipment added to the

vehicle.

Gross Combined Weight Rating (GCWR)

The resulting weight cannot exceed the

GCWR value on the Trailering Information

Label.

GCWR is the total allowable weight of the

completely loaded vehicle and trailer

including any fuel, passengers, cargo,

equipment, and accessories. Do not exceed

the GCWR for your vehicle. The GCWR for

the vehicle is on the Trailering Information

Label.

The GCWR can also be confirmed by

weighing the truck and trailer on a public

scale. The truck and trailer should be loaded

for the trip with passengers and cargo.

Driving and Operating

Maximum Trailer Weight

The maximum trailer weight rating is

calculated assuming the tow vehicle has a

driver, a front seat passenger, and all

required trailering equipment. This value

represents the heaviest trailer the vehicle

can tow, but it may be necessary to reduce

the trailer weight to stay within the GCWR,

GVWR, maximum trailer tongue load,

or GAWR-RR for the vehicle.

305

The alert will not activate unless:

GCWR is only one of the maximum weight

ratings applicable to your vehicle and trailer.

The GCW Alert does not estimate whether

the vehicle alone exceeds the GVWR, the

rear-axle weight exceeds GAWR-RR, the

trailer exceeds the Maximum Trailer Weight

Rating or the trailer tongue weight exceeds

the Maximum Tongue Weight Rating.

Always verify that the weight of the vehicle,

Weights listed apply for conventional trailers

and gooseneck/fifth-wheel trailers unless

otherwise noted.

Gross Vehicle Weight Rating (GVWR)

For information about the vehicle's

maximum load capacity, see Vehicle Load

Limits 0 204. When calculating the GVWR

with a trailer attached, the trailer tongue

weight must be included as part of the

weight the vehicle is carrying.

Warning

{

Always determine the actual weights of

the loaded vehicle and trailer using a

vehicle scale before beginning a trip.

Never use the GCW Alert to determine

whether the vehicle and trailer are

properly loaded or overloaded. Do not

drive with an overloaded vehicle or

trailer. Death, serious injury, or property

damage could occur.

A step bumper trailer hitch can only support

a total trailer weight up to 2 271 kg

(5,000 lb). If a trailer hitch ball is added to

the step bumper, check the hitch ball rating

to be sure it is higher than the total trailer

weight.

306

Driving and Operating

The trailer tongue weight contributes to the

Gross Vehicle Weight (GVW). GVW includes

the curb weight of your vehicle, any

passengers, cargo, equipment and the trailer

tongue weight. Vehicle options, passengers,

cargo, and equipment reduce the maximum

allowable tongue weight the vehicle can

carry, which also reduces the maximum

allowable trailer weight.

The trailer tongue weight (1) should be 10–

15% and fifth-wheel or gooseneck tongue

weight should be 15–25% of the total loaded

trailer weight (2). Some specific trailer types,

such as boat trailers, fall outside of this

range. Always refer to the trailer owner’s

manual for the recommended trailer tongue

weight for each trailer. Never exceed the

maximum loads for the vehicle, hitch, and

trailer.

Maximum Trailer Tongue Weight Rating

The Maximum Trailer Tongue Weight Rating

is the allowable trailer tongue weight that

the vehicle can support using a conventional

trailer hitch. It may be necessary to reduce

the overall trailer weight to stay within the

maximum trailer tongue weight rating while

still maintaining the correct trailer load

balance. A fifth-wheel or gooseneck hitch

may support a higher tongue weight.

Trailer Load Balance

The trailer load balance percentage is

calculated as: weight (1) divided by

weight (2) times 100.

The correct trailer load balance must be

maintained to ensure trailer stability.

Incorrect load balance is a leading cause of

trailer sway.

After loading the trailer, separately weigh

the trailer and then the trailer tongue and

calculate the trailer load balance percentage

to see if the weights and distribution are

appropriate for your vehicle. If the trailer

weight is too high, it may be possible to

transfer some of the cargo into your vehicle.

If the trailer tongue weight is too high or

too low, it may be possible to rearrange

some of the cargo inside of the trailer.

The Maximum Trailer Tongue Weight Rating

for a conventional trailer hitch or a fifth

wheel/gooseneck hitch is shown on the

Trailering Information Label.

In order to avoid serious injury or

If a cargo carrier is used in the trailer hitch

receiver, choose a carrier that positions the

property damage, always follow the hitch

manufacturer's instructions when securing

your draw bar/coupling device to the

vehicle's hitch receiver.

Ensure that the draw bar/coupling device

is secured with a locking retainer pin or

other means such that rotation of the pin

or locking mechanism will not cause the

pin to back out or loosen during use.

Failure to correctly secure the draw bar/

coupling device to the receiver can result

in separation of the hitch/receiver while

towing.

The GAWR-RR for the vehicle is on the

Trailering Information Label.

Rear Gross Axle Weight Rating

(GAWR-RR)

Ask your dealer for trailering information or

assistance.

The GAWR-RR is the total weight that can be

supported by the rear axle of the vehicle. Do

not exceed the GAWR-RR for the vehicle,

with the tow vehicle and trailer fully loaded

for the trip including the weight of the

trailer tongue. If using a weight-distributing

hitch, do not exceed the GAWR-RR before

applying the weight distribution spring bars.

308

Driving and Operating

Conventional Hitch

Always use the correct hitch equipment for

your vehicle. Crosswinds, large trucks going

by, and rough roads can affect the trailer

and the hitch.

Avoid sharp turns when using a step-bumper

hitch to prevent damage. Make wider turns

to prevent contact between your trailer and

your bumper.

A conventional hitch is bolted to the frame

or cross member of the tow vehicle, and is

generally rated Class 2, 3, or 4.

Proper hitch equipment for your vehicle

helps maintain control of the vehicle-trailer

combination. Many trailers can be towed

using a weight-carrying hitch which has a

coupler latched to the hitch ball, or a tow

eye latched to a pintle hook. Other trailers

may require a weight-distributing hitch that

uses spring bars to distribute the trailer

tongue weight between your vehicle and

trailer axles. Fifth-wheel and gooseneck

hitches may also be used. See “Maximum

Trailer Tongue Weight” under Trailer Towing

0 303 for weight limits with various hitch

types.

Consider using mechanical sway controls

with any trailer. Ask a trailering professional

about sway controls or refer to the trailer

manufacturer's recommendations and

instructions.

Gooseneck Hitch

A gooseneck hitch is designed to be coupled

to a special hitch leveraging a hitch ball, and

is mounted over the rear axle in the

truck bed.

Weight-Distributing Hitch and

Adjustment

Fifth-Wheel Hitch

A fifth-wheel hitch is mounted over the rear

leveraged by semi trucks. Generally,

fifth-wheel hitches accommodate large

trailers with as many as one, two, or three

axles.

The hitch should be in the pickup bed so

that its centerline is over or near the rear

axle. Take care that it is not so far forward

that it will contact the back of the cab in

sharp turns. This is especially important for

short box pickups. Trailer pin box extensions

and sliding fifth-wheel hitch assemblies may

be used. There should be at least 15 cm

(6 in) of clearance between the top of the

pickup box and the bottom of the trailer

shelf that extends over the box.

to the attaching points on the bumper;

otherwise, safety chains should be attached

to holes on the trailer hitch.

Fifth-Wheel and Gooseneck Trailering

Fifth-wheel and gooseneck trailers can be

used with many pickup models. These

trailers place a larger percentage of the

weight (kingpin weight) on the tow vehicle

than conventional trailers. Make sure this

weight does not cause the vehicle to exceed

GAWR or GVWR. Fifth-wheel or gooseneck

kingpin weight should be 15–25% of the

trailer weight up to the maximum amount

Cross the safety chains under the tongue of

the trailer to help prevent the tongue from

contacting the road if it becomes separated

from the hitch. Always leave enough slack in

the safety chains to allow the combination

to turn. Never allow safety chains to drag

on the ground.

Make sure the hitch is attached to the tow

vehicle frame rails. Do not use the pickup

box for support.

Trailer Sway Control (TSC)

If TSC is enabled, the Traction Control

Vehicles with StabiliTrak/Electronic Stability

Control (ESC) have a Trailer Sway Control

(TSC) feature. Trailer sway is unintended

side-to-side motion of a trailer while towing.

If the vehicle is towing a trailer and the TSC

detects that sway is increasing, the vehicle

brakes are selectively applied at each wheel,

to help reduce excessive trailer sway.

If equipped with the Integrated Trailer Brake

Control (ITBC) system, and the trailer has an

electric brake system, StabiliTrak/ESC may

also apply the trailer brakes.

System (TCS)/StabiliTrak/ESC warning light

will flash on the instrument cluster. Reduce

vehicle speed by gradually removing your

foot from the accelerator. If trailer sway

continues, StabiliTrak/ESC can reduce engine

torque to help slow the vehicle. TSC will not

function if StabiliTrak/ESC is turned off. See

conditions allow.

Trailer Tires

Special Trailer (ST) tires differ from vehicle

tires. Trailer tires are designed with stiff

sidewalls to help prevent sway and to

support heavy loads. These features can

make it difficult to determine if the trailer

tire pressures are low only based on a visual

inspection.

Ask the device or trailer manufacturer

if the device has been thoroughly

tested for compatibility with the

make, model, and year of your vehicle

and any optional equipment installed

on your vehicle.

Aftermarket Electronic Trailer Sway

Control Devices

Some trailers may come equipped with an

electronic device designed to reduce or

control trailer sway. Aftermarket equipment

manufacturers also offer similar devices that

connect to the wiring between the trailer

and the vehicle. These devices may interfere

with the vehicle’s trailer brake or other

systems, including integrated anti-sway

systems, if equipped. Messages related to

trailer connections or trailer brakes could

appear on the DIC. The effects of these

Always check all trailer tire pressures before

each trip when the tires are cool. Low trailer

tire pressure is a leading cause of trailer tire

blow-outs.

Drive the vehicle with the trailer

attached on a level road surface that

the airflow to the radiator. This could be

more noticeable as vehicle speed

increases. At speeds above 72 km/h

(45 mph), this may cause the engine

coolant to overheat. Move or angle the

snow plow blade to allow increased

airflow to the radiator.

To increase the airflow, move the snow

plow blade position.

If driving more than 24 km/h (15 mph),

angle the plow blade position.

Make sure the weight on the front and

rear axles does not exceed the axle rating

for each.

Follow the snowplow manufacturer’s

recommendations for any rear ballast that

may be required. Rear ballast may be

required to ensure a proper front and rear

weight distribution ratio even though the

actual weight at the front axle may be

less than the front axle rating.

The snowplow manufacturer or installer

can assist in determining the amount of

rear ballast required to ensure that the

vehicle with the attached snowplow does

not exceed the GVW rating, the front and

rear axle ratings, or the front and rear

weight distribution ratio (refer to the GM

Upfitter Manual).

Caution (Continued)

repairs would not be covered by the

vehicle warranty. Unless the vehicle was

built to carry a snow plow, do not add

one to the vehicle. If the vehicle has RPO

VYU, then the payload the vehicle can

carry will be reduced when a snow plow

is installed. The vehicle can be damaged

if either the front or rear axle ratings or

the Gross Vehicle Weight Rating (GVWR)

are exceeded.

Adding a Snow Plow or Similar

Equipment

The plow the vehicle can carry depends on

many things, such as:

The options the vehicle came with, and

the weight of those options.

The weight and number of passengers to

be carried.

The weight of items added to the vehicle,

like a tool box or truck cap.

.

Caution

Do not exceed 72 km/h (45 mph) with a

snow plow mounted to the vehicle. The

vehicle could overheat and be damaged.

Before installing a snow plow on the vehicle,

follow these guidelines:

.

The total weight of any additional cargo

to be carried.

Caution

To safely carry a snow plow on the vehicle:

If the vehicle does not have the snow

plow prep package, RPO VYU, adding a

plow can damage the vehicle, and the

Front axle reserve capacity is the difference

between the Front Gross Axle Weight

Rating (GAWR) and the front axle weight of

the vehicle with full fuel, passengers, and

any other cargo. This is the amount of

weight that can be added to the front axle

before reaching the Front GAWR.

Where:

IW = Weight of added accessory

on the front. However, the front GAWR, rear

GAWR, and Gross Vehicle Weight

Rating (GVWR) must never be exceeded.

IA = Distance that the accessory is in

front of the front axle

{

IW.B. = Vehicle Wheelbase

On some vehicles that have certain front

mounted equipment, such as a snow

plow, it may be possible to load the front

axle to the front Gross Axle Weight

Rating (GAWR) but not have enough

weight on the rear axle to have proper

braking performance. If the brakes cannot

work properly, the vehice could crash.

Always follow the snow plow

For example, adding a 318 kg (700 lb) snow

plow actually adds more than 318 kg (700 lb)

to the front axle. Using the formula, if the

snow plow is 122 cm (4 ft) in front of the

front axle and the wheelbase is 305 cm

(10 ft), then:

To calculate the amount of weight any front

accessory, such as a snow plow, is adding to

the front axle, use this formula:

IW = 318 kg (700 lb)

IA = 122 cm (4 ft)

manufacturer or installer's

IW.B. = 305 cm (10 ft)

recommendation for rear ballast to

ensure a proper front and rear weight

distribution ratio. Maintaining a proper

front and rear weight distribution ratio is

necessary to provide proper braking

performance.

(W x (A + W.B.)/W.B. = (318 x (122 + 305))/305

= 445 kg (980 lb)

This means if the front axle reserve capacity

is more than 445 kg (980 lb), the snow plow

could be added without exceeding the

front GAWR.

See your dealer for additional advice and

information about using a snow plow on the

vehicle. Also, see Vehicle Load Limits 0 204.

(W x (A + W.B.)) /W.B.= Weight the accessory

is adding to the front axle.

Heavier equipment can be added on the

front of the vehicle if less cargo or fewer

passengers are carried, or by positioning

cargo toward the rear. This reduces the load

Pickup Conversion to Chassis Cab

We are aware that some vehicle owners

might consider having the pickup box

removed and a commercial or recreational

body installed. Owners should be aware

that, as manufactured, there are differences

between a chassis cab and a pickup with the

box removed which could affect vehicle

safety. The components necessary to adapt

a pickup to permit its safe use with a

specialized body should be installed by the

body builder.
