CAUTION!
Never park your vehicle over dry grass or other com-
bustible materials. The heat from your vehicle exhaust
system could cause a fire.
WARNING!
Always wear your seat belt and firmly tie down cargo.
Unsecured cargo can become projectiles in an off-road
situation.
When To Use Low Range
When driving off-road, shift into 4LO (Low Range) for
additional traction or to improve handling and control on
slippery or difficult terrain. Due to the lower gearing, low
range will allow the engine to operate in a higher power
range. This will allow you to idle over obstacles and down
hills, with improved control and less effort. Also, use 4LO
(Low Range) in rain, ice, snow, mud, sand, to get heavy
loads rolling, improve traction, or whenever 4HI (High
Range) traction will not do the job.
Driving In Snow, Mud And Sand
There is a drastic reduction in traction when driving in
snow, mud or sand. The vehicle will be less responsive to
steering, acceleration and braking inputs. Therefore you
should accelerate slowly, leave greater stopping distances
and avoid abrupt vehicle maneuvers. You want to keep a
slow constant steady pace. The key is to maintain the
vehicle’s momentum.
•Snow – In heavy snow or for additional control and
traction at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4LO (Low Range) if
necessary. Do not shift to a lower gear than necessary to
maintain headway. Over-revving the engine can spin the
wheels and traction will be lost. If you start to slow to a
stop, try turning your steering wheel no more than a ¼
turn quickly back and forth, while still applying throttle.
This will allow the tires to get a fresh biteand help
maintain your momentum.
CAUTION!
On icy or slippery roads, do not downshift at high
engine RPMs or vehicle speeds because engine brak-
ing may cause skidding and loss of control.

Engine Air Cleaner Filter Installation
NOTE:Inspect and clean the housing if dirt or debris is
present before replacing the air filter element.
1. Install the air cleaner filter element into the housing assembly with the air cleaner filter inspection surface
facing downward.
2. Install the air cleaner cover onto the housing assembly locating tabs.
3. Latch the spring clips and lock the air cleaner cover to the housing assembly.Accessory Drive Belt Inspection
WARNING!
•Do not attempt to inspect an accessory drive belt
with vehicle running.
• When working near the radiator cooling fan, discon-
nect the fan motor lead. The fan is temperature
controlled and can start at any time regardless of
ignition mode. You could be injured by the moving
fan blades.
• You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.
646 MAINTAINING YOUR VEHICLE
When inspecting accessory drive belts, small cracks that
run across ribbed surface of belt from rib to rib, are
considered normal. These are not a reason to replace belt.
However, cracks running along a rib (not across) are not
normal. Any belt with cracks running along a rib must be
replaced. Also have the belt replaced if it has excessive
wear, frayed cords or severe glazing.Conditions that would require replacement:
•
Rib chunking (one or more ribs has separated from belt
body)
• Rib or belt wear
• Longitudinal belt cracking (cracks between two ribs)
• Belt slips
• “Groove jumping (belt does not maintain correct posi-
tion on pulley)
• Belt broken (identify and correct problem before new
belt is installed)
• Noise (objectionable squeal, squeak, or rumble is heard
or felt while drive belt is in operation)
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.
Belt replacement on some models requires the use of
special tools, we recommend having your vehicle serviced
at an authorized dealer.

Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
WARNING!
•Use only refrigerants and compressor lubricants ap-
proved by the manufacturer for your air conditioning
system. Some unapproved refrigerants are flam-
mable and can explode, injuring you. Other unap-
proved refrigerants or lubricants can cause the sys-
tem to fail, requiring costly repairs. Refer to
Warranty Information Book, located on the DVD, for
further warranty information.
• The air conditioning system contains refrigerant un-
der high pressure. To avoid risk of personal injury or
damage to the system, adding refrigerant or any
repair requiring lines to be disconnected should be
done by an experienced technician.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condition-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.

MAINTAINING YOUR VEHICLE 649
CAUTION!
Do not use Alcohol and Alcohol-based and/or Keton
based cleaning products to clean leather seats, as
damage to the seat may result.
Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog
lights that are lighter and less susceptible to stone breakage
than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
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.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
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 equippedwith electric defrosters or windows equipped with radio
antennas. Do not use scrapers or other sharp instrument
that may scratch the elements.
When cleaning the rear view mirror, spray cleaner on the
towel or cloth that you are using. Do not spray cleaner
directly on the mirror.
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.
1. 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.
2. Dry with a soft cloth.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chemical solvents
or abrasive cleaners. This will weaken the fabric. Sun
damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution or
lukewarm water. Do not remove the belts from the vehicle
to wash them. Dry with a soft cloth.
7
MAINTAINING YOUR VEHICLE 677
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
NOTE:If the belts retract slowly, inspect the upper turning
loop for soiling. If soiling is present, clean with a wet soft
cloth until all residue is removed.
WARNING!
A frayed or torn belt could rip apart in a collision and
leave you with no protection. Inspect the belt system
periodically, checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately. Do not
disassemble or modify the system. Seat belt assemblies
must be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing, etc.).
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.
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 expo-
sure will lead to fading, dulling, and loss of gloss over
time.
To help maintain the appearance of your Spray-On Bed-
liner, 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 your local authorized 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.
