Cleaning Plastic Instrument Cluster  
Lenses  
The lenses in front of the instruments in this vehicle are  
molded in clear plastic. When cleaning the lenses, care  
must be taken to avoid scratching the plastic.  
GLASS SURFACES  
All glass surfaces should be cleaned on a regular basis  
with Mopar® Glass Cleaner, or any commercial  
household-type glass cleaner. Never use an abrasive type  
cleaner. Use caution when cleaning the inside rear  
window equipped with electric defrosters or windows  
equipped with radio antennas. Do not use scrapers or  
other sharp instruments that may scratch the elements.  
If equipped with light colored leather, it tends to show any  
foreign material, dirt, and fabric dye transfer more so than  
darker colors. The leather is designed for easy cleaning,  
and the manufacturer recommends Mopar® Total Clean  
leather cleaner applied on a cloth to clean the leather  
seats as needed.  
Clean with a wet soft cloth. A mild soap solution may be  
used, but do not use high alcohol content or abrasive  
cleaners. If soap is used, wipe clean with a clean damp  
cloth. Dry with a soft cloth.  
CAUTION!  
When cleaning the rearview mirror, spray cleaner on the  
towel or cloth that you are using. Do not spray cleaner  
directly on the mirror.  
Do not use alcohol and alcohol-based and/or  
ketone-based cleaning products to clean leather  
upholstery, as damage to the upholstery may result.  
LEATHER SURFACES  
Mopar® Total Clean is specifically recommended for  
leather upholstery.  
Your leather upholstery can be best preserved by regular  
cleaning with a damp soft cloth. Small particles of dirt can  
act as an abrasive and damage the leather upholstery and  
should be removed promptly with a damp cloth. Stubborn  
soils can be removed easily with a soft cloth and Mopar®  
Total Clean. Care should be taken to avoid soaking your  
leather upholstery with any liquid. Please do not use

TECHNICAL SPECIFICATIONS  
If either the front or rear hydraulic systems lose normal  
braking capability, the remaining system will still function  
with some loss of overall braking effectiveness. This will  
be evident by increased pedal travel during application,  
greater pedal force required to slow or stop, and the Brake  
Warning Light and the Anti-Lock Brake System (ABS)  
Warning Light will activate during brake use.  
**Use only authorized dealer recommended lug  
nuts/bolts and clean or remove any dirt or oil before  
tightening.  
VEHICLE IDENTIFICATION NUMBER (VIN)  
The VIN is found on the left front corner of the instrument  
panel, visible through the windshield.  
NOTE:  
Do not oil wheel studs. For chrome wheels, do not  
substitute with chrome plated wheel nuts.  
Inspect the wheel mounting surface prior to mounting the  
tire and remove any corrosion or loose particles.  
WHEEL AND TIRE TORQUE SPECIFICATIONS  
Proper lug nut/bolt torque is very important to ensure that  
the wheel is properly mounted to the vehicle. Any time a  
wheel has been removed and reinstalled on the vehicle,  
the lug nuts/bolts should be torqued using a properly  
calibrated torque wrench using a six-sided (hex) deep wall  
socket.

Tighten the lug nuts/bolts in a star pattern until each nut/  
bolt has been tightened twice. Ensure that the socket is  
fully engaged on the lug nut/bolt (do not insert it halfway).  
If power assist is lost for any reason (for example,  
repeated brake applications with the engine off), the  
brakes will still function. However, you will experience a  
substantial increase in braking effort to stop the vehicle.  
TECHNICAL SPECIFICATIONS 393  
After 25 miles (40 km), check the lug nut/bolt torque to be  
sure that all the lug nuts/bolts are properly seated against  
the wheel.  
Poor quality gasoline can cause problems such as hard  
starting, stalling, and hesitations. If you experience these  
symptoms, try another brand of gasoline before  
considering service for the vehicle.  
REFORMULATED GASOLINE  
Many areas of the country require the use of  
cleaner-burning gasoline referred to as “reformulated  
gasoline”. Reformulated gasoline contains oxygenates  
and are specifically blended to reduce vehicle emissions  
and improve air quality.  
3.6L ENGINE  
Do not use E-85 flex fuel or ethanol blends greater than  
15% in this engine.  
The use of reformulated gasoline is recommended.  
Properly blended reformulated gasoline will provide  
improved performance and durability of engine and fuel  
system components.  
This engine is designed to meet all emissions  
regulations and provide optimum fuel economy  
and performance when using high quality  
unleaded regular gasoline having a posted  
octane number of 87 as specified by the (R+M)/2 method.  
The use of higher octane premium gasoline is not  
required, as it will not provide any benefit over regular  
gasoline in these engines.  
MATERIALS ADDED TO FUEL  
Besides using unleaded gasoline with the proper octane  
rating, gasolines that contain detergents, corrosion and  
stability additives are recommended. Using gasolines that  
have these additives will help improve fuel economy,  
reduce emissions, and maintain vehicle performance.  
Four, Five, And Six Lug Nuts/Bolts Torque Patterns  
WARNING!  
5.7L ENGINE  
To avoid the risk of forcing the vehicle off the jack, do  
not tighten the lug nuts/bolts fully until the vehicle has  
been lowered. Failure to follow this warning may result  
in personal injury.  
Designated TOP TIER Detergent Gasoline  
contains a higher level of detergents to further  
aide in minimizing engine and fuel system  
deposits. When available, the usage of TOP  
TIER Detergent Gasoline is recommended. Visit  
www.toptiergas.com for a list of TOP TIER Detergent  
Gasoline retailers.  
Do not use E-85 flex fuel or ethanol blends greater than  
15% in this engine.  
This engine is designed to meet all emissions  
regulations and provide satisfactory fuel  
economy and performance when using  
high-quality unleaded gasoline having an  
octane range of 87 to 89 as specified by the (R+M)/  
2 method. The use of 89 octane plus gasoline is  
recommended for optimum performance and fuel  
economy.  
FUEL REQUIREMENTS  
9
Indiscriminate use of fuel system cleaning agents should  
be avoided. Manyof these materials intended for gum and  
varnish removal may contain active solvents or similar  
ingredients. These can harm fuel system gasket and  
diaphragm materials.  
While operating on gasoline with the required octane  
number, hearing a light knocking sound from the engine is  
not a cause for concern. However, if the engine is heard  
making a heavy knocking sound, see a dealer  
immediately. Use of gasoline with a lower than  
recommended octane number can cause engine failure  
and may void or not be covered by the New Vehicle  
Limited Warranty.  
394 TECHNICAL SPECIFICATIONS  
If a Non-FFV vehicle is inadvertently fueled with E-85 fuel,  
the engine will have some or all of these symptoms:  
The MMT content of gasoline may not be indicated on the  
gasoline pump; therefore, you should ask the gasoline  
retailer whether the gasoline contains MMT. MMT is  
prohibited in Federal and California reformulated  
gasoline.  
GASOLINE/OXYGENATE BLENDS  
Some fuel suppliers blend unleaded gasoline with  
oxygenates such as ethanol.  
Operate in a lean mode.  
OBD II Malfunction Indicator Light on.  
Poor engine performance.  
CAUTION!  
FUEL SYSTEM CAUTIONS  
Poor cold start and cold drivability.  
Increased risk for fuel system component corrosion.  
DO NOT use E-85, gasoline containing methanol, or  
gasoline containing more than 15% ethanol (E-15).  
Use of these blends may result in starting and  
drivability problems, damage critical fuel system  
components, cause emissions to exceed the applicable  
standard, and/or cause the Malfunction Indicator Light  
to illuminate. Please observe pump labels as they  
should clearly communicate if a fuel contains greater  
than 15% ethanol (E-15).  
CAUTION!  
CNG AND LP FUEL SYSTEM  
MODIFICATIONS  
Modifications that allow the engine to run on Compressed  
Natural Gas (CNG) or Liquid Propane (LP) may result in  
damage to the engine, emissions, and fuel system  
components. Problems that result from running CNG or LP  
are not the responsibility of the manufacturer and may  
void the New Vehicle Limited Warranty.  
Follow these guidelines to maintain your vehicle’s  
performance:  
The use of leaded gasoline is prohibited by Federal  
law. Using leaded gasoline can impair engine perfor-  
mance and damage the emissions control system.  
An out-of-tune engine or certain fuel or ignition  
malfunctions can cause the catalytic converter to  
overheat. If you notice a pungent burning odor or  
some light smoke, your engine may be out of tune or  
malfunctioning and may require immediate service.  
Contact an authorized dealer for service assistance.  
Problems that result from using gasoline containing more  
than 15% ethanol (E-15) or gasoline containing methanol  
are not the responsibility of the manufacturer and may  
void the New Vehicle Limited Warranty.  
METHYLCYCLOPENTADIENYL  
MANGANESE TRICARBONYL (MMT) IN  
GASOLINE  
MMT is a manganese-containing metallic additive that is  
blended into some gasolines to increase octane. Gasoline  
blended with MMT provides no performance advantage  
beyond gasoline of the same octane number without  
MMT. Gasoline blended with MMT reduces spark plug life  
and reduces emissions system performance in some  
vehicles. The manufacturer recommends that gasoline  
without MMT be used in your vehicle.  
DO NOT USE E-85 IN NON-FLEX FUEL  
VEHICLES  
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline  
containing up to 15% ethanol (E-15). Use of gasoline with  
higher ethanol content may void the New Vehicle Limited  
Warranty.  
The use of fuel additives, which are now being sold  
as octane enhancers, is not recommended. Most of  
these products contain high concentrations of meth-  
anol. Fuel system damage or vehicle performance  
problems resulting from the use of such fuels or addi-  
tives is not the responsibility of the manufacturer  
and may void or not be covered under the New  
Vehicle Limited Warranty.  
NOTE:  
Intentional tampering with the emissions control system  
can result in civil penalties being assessed against you.
