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.
 It is important that the drain holes in the lower edges of
the doors, rocker panels, and trunk be kept clear and
open.
 If you detect any stone chips or scratches in the paint,
touch them up immediately.
 If your vehicle is damaged due to a collision or similar
cause that destroys the paint and protective coating,
have your vehicle repaired as soon as possible. 
If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., be sure that such materials are well
packaged and sealed.
 If a lot of driving is done on gravel roads, consider mud
or stone shields behind each wheel.
 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.
Spray-On Bedliner – If Equipped
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 loose dirt from 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.
To Help Maintain The Appearance Of Your Spray-On
Bedliner

1. Rinse your truck bed out with water to remove any loose dirt and debris.

2. Mix a mild soap or detergent with water. Then apply solution with a soft cloth or brush.
3. Rinse bedliner with water. 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.
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.
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.
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.
 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.
WARNING!
Do not use silicon-based protection products to clean
your bedliner. Silicon-based products can become
slippery and may result in personal injury.

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.
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.
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
polishes, oils, cleaning fluids, solvents, detergents, or
ammonia-based cleaners to clean your leather upholstery.
NOTE: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.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.
When cleaning the rearview mirror, spray cleaner on the
towel or cloth that you are using. Do not spray cleaner
directly on the mirror.

VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the instrument
panel, visible through the windshield.

Vehicle Identification Number

NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
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. 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.
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.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug
nuts/bolts and clean or remove any dirt or oil before
tightening.
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.

FUEL REQUIREMENTS
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. 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.
3.6L ENGINE
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 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.
5.7L ENGINE
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.
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.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will provide
improved performance and durability of engine and fuel
system components.
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.
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.
Indiscriminate use of fuel system cleaning agents should
be avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and
diaphragm materials.
WARNING!
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.

GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
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.
DO NOT USE E-85 IN NON-FLEX FUEL
V
EHICLES
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. If a Non-FFV vehicle is inadvertently fueled with E-85 fuel,
the engine will have some or all of these symptoms:

Operate in a lean mode.
 OBD II Malfunction Indicator Light on.
 Poor engine performance.
 Poor cold start and cold drivability.
 Increased risk for fuel system component corrosion.
CNG AND LP FUEL SYSTEM
M
ODIFICATIONS
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.
METHYLCYCLOPENTADIENYL
M
ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
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. 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.
FUEL SYSTEM CAUTIONS
NOTE:Intentional tampering with the emissions control system
can result in civil penalties being assessed against you.
CAUTION!
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!
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.
 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.
