Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever
necessary, install ONLY the correct type ther -
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.
Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned below the
radiator and the air conditioner condenser. Air
enters the engine through the air cleaner and
passes through the turbocharger, where it is
pressurized. This pressurized air rapidly
reaches high temperature. The air is then
directed through a hose to the charge air cooler
and through another hose to the intake mani -
fold of the engine. The air entering the engine
has been cooled by about 50° to 100°F (10° to
38°C). This cooling process enables more effi -
cient burning of fuel resulting in fewer emis -
sions.
To guarantee optimum performance of the
system, keep the surfaces of the charge air
cooler, condenser and radiator clean and free of debris. Periodically check the hoses leading
to and from the charge air cooler for cracks or
loose clamps resulting in loss of pressure and
reduced engine performance.
Brake System
In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the “Mainte
-
nance Plan” in this section for the proper main -
tenance intervals.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be
checked when performing under the hood
service or immediately if the brake system
warning lamp indicates system failure. 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 the fluid level can be expected
to fall as the brake linings wear. However, an
unexpected drop in fluid level may be caused by
a leak and a system check should be
conducted.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
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.WARNING!
Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri
-
cants” in “Technical Specifications” for
further information. Using the wrong type of
brake fluid can severely damage your 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 reser -
voir.

If you detect any stone chips or scratches in
the paint, touch them up immediately. The
cost of such repairs is considered the respon -
sibility of the owner.
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. The cost of such repairs
is considered the responsibility of the owner.
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,
dulling, and loss of gloss over time.
To help maintain the appearance of your
Spray-On Bedliner, the manufacturer recom
-
mends 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 autho -
rized dealer.
To Help Maintain The Appearance Of Your
Spray-On Bedliner, Follow The Steps Below:

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

2. Mix a mild soap or detergent with water 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.
WARNING!
Do not use silicon-based protection products
to clean your bedliner. Silicon-based products
can become slippery and may result in
personal injury.
