Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can even-
tually poison you. To avoid breathing (CO), follow
these safety tips:
•Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
• If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
• If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling con-
trols to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the vehicle, or when the underside or rear of the vehicle is
damaged, have a competent mechanic inspect the complete
exhaust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, inspect the ex-
haust system each time the vehicle is raised for lubrication
or oil change. Replace as required.
Safety Checks You Should Make Inside The Vehicle
Seat Belts
Inspect the seat belt system periodically, checking for cuts,
frays, and loose parts. Damaged parts must be replaced
immediately. Do not disassemble or modify the system.
Front seat belt assemblies must be replaced after a collision.
Rear seat belt assemblies must be replaced after a collision
if they have been damaged (i.e., bent retractor, torn web-
bing, etc.). If there is any question regarding seat belt or
retractor condition, replace the seat belt.
Air Bag Warning Light
The Air Bag warning lightwill turn on for four to
eight seconds as a bulb check when the ignition switch
is first turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while driving, 5

and ice. Every surface has a different effect on your
vehicle’s steering, handling and traction. Controlling your
vehicle is one of the keys to successful off-road driving, so
always keep a firm grip on the steering wheel and maintain
a good driving posture. Avoid sudden accelerations, turns
or braking. In most cases there are no road signs, posted
speed limits or signal lights. Therefore you will need to use
your own good judgment on what is safe and what isn’t.
When on a trail you should always be looking ahead for
surface obstacles and changes in terrain. The key is to plan
your future driving route while remembering what you are
currently driving over.
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
364 STARTING AND OPERATING

start high and lower it as required. Remember you must
return the tires to normal air pressure before driving on
road or at highway conditions. Be sure you have a way to
return the tires to their normal on road air pressure.
CAUTION!
Reduced tire pressure increases the risk of tire damage
and may cause tire unseating with total loss of air
pressure. To reduce the risk of tire unseating, while at
a reduced tire pressure, drive at slower speeds and
avoid sharp turns or abrupt maneuvers.
Vehicle Recovery
If you drive off-road, you may encounter a situation where
you will need to recover your vehicle. Vehicle recovery
should always be given consideration before attempting a
questionable obstacle. You should never go off-road driv-
ing without the ability to recover your vehicle from a
situation. Having another vehicle with you usually works
best for most situations. The first thing to do is assess the
situation. Why are you stuck? Are you hung up on
something? Would it be easier to go forward or to go
backward? Can you still move the vehicle? Is there an
anchor point to winch to? Are you alone or do you have
another vehicle to help? Is there high risk of vehicledamage during the recovery process? Answering these
questions will help you determine the best method of
recovery. If you can still move the vehicle slightly and the
only issue is slick ground, then rock cycling your vehicle
would be the first choice. If you have ample room, an
additional vehicle and there is low risk of vehicle impinge-
ment on the surroundings, then using a tow strap to the
vehicle tow hooks would be fast and easy. If the vehicle is
severely hung up or in a situation where great care needs
to be taken during the recovery, then nothing can do the job
better than a winch. If you are severely hung up on
something you should jack the vehicle up and stack
something under the wheels to allow the vehicle to roll off
the object without causing further damage. This should be
tried before attempting any recovery method.
CAUTION!
Pulling the vehicle off an obstacle, without first clear-
ing the object, may result in additional underbody
damage.
• Rock Cycling Your Vehicle – Rock cycling your vehicle
is one of the easiest, fastest and most commonly used
methods. This simply involves shifting your vehicle
from DRIVE to REVERSE, while applying throttle after

CAUTION!(Continued)
•The rear hub caps on the dual rear wheel has two
pull off notches. Make sure that the hook of the jack
handle driver is located squarely in the cap notch
before attempting to pull off.
You must use the flat end of the lug wrench to pull off the
wheel skins. Locate the hub cap pull notches (2 notches on
each cap). Insert the flat tip completely and using a back
and forth motion, loosen the wheel skin. Repeat this
procedure around the tire until the skin pops off.
Replace the wheel skins first using a rubber mallet. When
replacing the hub caps, tilt the cap retainer over the lug nut
bolt circle and strike the high side down with a rubber
mallet. Be sure that the hub caps and wheel skins are firmly
seated around the wheel.
JUMP STARTING
If your vehicle has a discharged battery, it can be jump
started using a set of jumper cables and a battery in another
vehicle, or by using a portable battery booster pack. Jump
starting can be dangerous if done improperly, so please
follow the procedures in this section carefully.
WARNING!
Do not attempt jump starting if the battery is frozen. It
could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any other
booster source with a system voltage greater than
12 Volts or damage to the battery, starter motor, alter-
nator or electrical system may occur.
NOTE: When using a portable battery booster pack, follow
the manufacturer’s operating instructions and precautions.
Preparations For Jump Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE: The positive battery post may be covered with a
protective cap if equipped. Lift up on the cap to gain access
to the positive battery post. Do not jump off fuses. Only
jump directly off positive post which has a positive (+)
symbol on or around the post.

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 (note: 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.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should be
lubricated periodically with a lithium based grease, such as
Mopar Spray White Lube to assure quiet, easy operation
and to protect against rust and wear. Prior to the applica-
tion of any lubricant, the parts concerned should be wiped
clean to remove dust and grit; after lubricating excess oil
and grease should be removed. Particular attention should
also be given to hood latching components to ensure
proper function. When performing other underhood ser-
vices, the hood latch, release mechanism and safety catch
should be cleaned and lubricated.
