Towing Tips
Before setting out on a trip, practice turning, stopping, and
backing up the trailer in an area located away from heavy
traffic.
Manual Transmission — If Equipped
If using a manual transmission vehicle for trailer towing,
all starts must be in first gear to avoid excessive clutch
slippage.
Automatic Transmission — If Equipped
The DRIVE range can be selected when towing. However,
if frequent shifting or changes in engine speed occur while
in this range, use the AutoStick shift control (if equipped)
to select a lower gear ratio.
NOTE:
•Using a lower gear ratio while operating the vehicle
under heavy loading conditions, will improve perfor-
mance and extend transmission life by reducing exces-
sive shifting and heat buildup. This action will also
provide better engine braking.
• If you REGULARLY tow a trailer for more than 45
minutes of continuous operation, then change the trans-
mission fluid and filter as specified for police, taxi, fleet,
or frequent trailer towing. Refer to the Maintenance
Plan for the proper maintenance intervals.

low (L Off-Road [if equipped]) with the 4WD LOCK
engaged and proceed with caution maintaining your mo-
mentum as you climb the hill.
Driving Up Hill
Once you have determined your ability to proceed and
have shifted into the appropriate gear, line your vehicle up
for the straightest possible run. Accelerate with an easy
constant throttle and apply more power as you start up the
hill. Do not race forward into a steep grade; the abrupt
change of grade could cause you to lose control. If the front
end begins to bounce, ease off the throttle slightly to bring
all four tires back on the ground. As you approach the crest
of the hill, ease off the throttle and slowly proceed over the
top. If the wheels start to slip as you approach the crest of
a hill, ease off the accelerator and maintain headway by
turning the steering wheel no more than a 1/4 turn quickly
back and forth. This will provide a freshbiteinto the
surface and will usually provide enough traction to com-
plete the climb. If you do not make it to the top, place the
vehicle in REVERSE and back straight down the grade
using engine resistance along with the vehicle brakes.WARNING!
Never attempt to climb a hill at an angle or turn around
on a steep grade. Driving across an incline increases
the risk of a rollover, which may result in severe injury.
Driving Down Hill
Before driving down a steep hill you need to determine if
it is too steep for a safe descent. What is the surface
traction? Is the grade too steep to maintain a slow con-
trolled descent? Are there obstacles? Is it a straight descent?
Is there plenty of distance at the base of the hill to regain
control if the vehicle descends to fast? If you feel confident
in your ability to proceed then make sure you are in low (L
Off-Road [if equipped] ) with the 4WD LOCK engaged and
proceed with caution. Allow engine and hill descent brak-
ing to control the descent and apply your brakes if neces-
sary, but do not allow the tires to lock.
WARNING!
Do not descend a steep grade in NEUTRAL. Use
vehicle brakes in conjunction with engine braking.
Descending a grade too fast could cause you to lose
control and be seriously injured or killed.

Driving Across An Incline
If at all possible avoid driving across an incline. If it is
necessary, know your vehicle’s abilities. Driving across an
incline places more weight on the down-hill wheels, which
increases the possibilities of a down-hill slide or rollover.
Make sure the surface has good traction with firm and
stable soils. If possible transverse the incline at an angle
heading slightly up or down.
WARNING!
Driving across an incline increases the risk of a roll-
over, which may result in severe injury.
If You Stall Or Begin To Lose Headway
If you stall or begin to lose headway while climbing a steep
hill, allow your vehicle to come to a stop and immediately
apply the brake. Restart the engine and shift to REVERSE.
Back slowly down the hill allowing engine and hill descent
braking to control the descent and apply your brakes if
necessary, but do not allow the tires to lock.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and
rolling the vehicle, which may result in severe injury.
Always back carefully straight down a hill in RE-
VERSE gear. Never back down a hill in NEUTRAL
using only the vehicle brakes. Never drive diagonally
across a hill, always drive straight up or down.
Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible, and only be
attempted when necessary in a safe responsible manner.
You should only drive through areas which are designated
and approved. You should tread lightly and avoid damage
to the environment. You should know your vehicles abili-
ties and be able to recover it if something goes wrong. You
should never stop or shut a vehicle off when crossing deep
water unless you ingested water into the engine air intake.
If the engine stalls, do not attempt to restart it. Determine
if it has ingested water first. The key to any crossing is low
and slow. You want to use low (L Off-Road [if equipped] )
with the 4WD LOCK engaged and proceed very slowly
240 STARTING AND OPERATING

with a constant slow speed (3-5 mph [5–8 km/h] maxi-
mum) and light throttle. Keep the vehicle moving; do not
try to accelerate through the crossing. After crossing any
water higher than the bottom of the axle differentials, you
should inspect all of the vehicle fluids for signs of water
ingestion.
CAUTION!
Water ingestion into the transaxle, transfer case, engine
or vehicle interior can occur if you drive too fast or
through too deep of water. Water can cause permanent
damage to engine, driveline or other vehicle compo-
nents and your brakes will be less effective once wet
and/or muddy.
Before You Cross Any Type Of Water
As you approach any type of water, you need to determine
if you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a stick.
You need to be sure of its depth, approach angle, current
and bottom condition. Be careful of murky or muddy
waters; check for hidden obstacles. Make sure you will not
be intruding on any wildlife, and you can recover the
vehicle if necessary. The key to a safe crossing is the water
depth, current and bottom conditions. On soft bottoms, the vehicle will sink in, effectively increasing the water level on
the vehicle. Be sure to consider this when determining the
depth and the ability to safely cross.
Crossing Puddles, Pools, Flooded Areas Or Other
Standing Water
Puddles, pools, flooded or other standing water areas
normally contain murky or muddy waters. These water
types normally contain hidden obstacles and make it
difficult to determine an accurate water depth, approach
angle, and bottom condition. Murky or muddy water holes
are where you want to hook up tow straps prior to
entering. This makes for a faster, cleaner and easier vehicle
recovery. If you are able to determine you can safely cross,
than proceed using the low and slow method.
CAUTION!
Muddy waters can reduce the cooling system effective-
ness by depositing debris onto the radiator.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is

always a good idea to check for damage. That way you can
get any problems taken care of right away and have your
vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts.
• After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a wheel
imbalance and freeing the wheels of it will correct the
situation.

MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• 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 thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” for the proper maintenance
intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly 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.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately if
the brake system warning light is on.
Be sure to clean the top of the master cylinder area before
removing the cap. If necessary, add fluid to bring the fluid
level up to the requirements described on the brake fluid
reservoir. Fluid level can be expected to fall as the brake
pads wear. The brake fluid level should be checked when
the pads are replaced. However, low fluid level may be
caused by a leak and a checkup may be needed.
NOTE:If your vehicle is equipped with a manual trans-
mission, the brake fluid reservoir supplies fluid to both the
brake system and the clutch release system. The two
systems are separated in the reservoir, and a leak in one
system will not affect the other system. The manual
transmission clutch release system should not require fluid
replacement during the life of the vehicle. If the brake fluid

select a non-abrasive, non-acidic cleaner for aluminum or
chrome wheels. Do not use any products on Dark Vapor or
Black Satin Chrome Wheels. They will permanently dam-
age this finish and such damage is not covered by the New
Vehicle Limited Warranty.
CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
metal polishes or oven cleaner. These products may
damage the wheel’s protective finish. Such damage is
not covered by the New Vehicle Limited Warranty.
Only car wash soap, MOPAR Wheel Cleaner or equiva-
lent is recommended.
NOTE: If you intend parking or storing your vehicle for an
extended period after cleaning the wheels with wheel
cleaner, drive your vehicle for a few minutes before doing
so. Driving the vehicle and applying the brakes when
stopping will reduce the risk of brake rotor corrosion. Dark Vapor Or Black Satin Chrome Wheels
CAUTION!
If your vehicle is equipped with Dark Vapor or Black
Satin Chrome wheels DO NOT USE wheel cleaners,
abrasives or polishing compounds. They will perma-
nently damage this finish and such damage is not
covered by the New Vehicle Limited Warranty. USE
ONLY MILD SOAP AND WATER WITH A SOFT
CLOTH. Used on a regular basis this is all that is
required to maintain this finish.
Tire Chains (Traction Devices)
Due to limited clearance, tire chains or traction devices are
not recommended.
CAUTION!
Damage to the vehicle may result if tire chains are
used.

VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (VIN) is found on the
left front corner of the instrument panel, visible through
the windshield. This number also is stamped into the right
front body, on the right front seat crossmember under the
carpet and the vehicle registration and title.NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with power assisted brakes as
standard equipment. In the event power assist is lost for
any reason (for example, repeated brake applications with
the engine off), the brakes will still function. However, the
effort required to brake the vehicle will be much greater
than that required with the power system operating.

WARNING!
Riding the brakes can lead to brake failure and possi-
bly 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.
If either of the two hydraulic systems lose normal capability,
the remaining system will still function with some loss of
overall braking effectiveness. This will be evident by increased
pedal travel during application and greater pedal force re-
quired to slow or stop. In addition, if the malfunction is caused
by an internal leak, as the brake fluid in the master cylinder
drops, the “Brake Warning Light” will light.
WARNING!
Driving a vehicle with the “Brake Warning Light” on is
dangerous. A significant decrease in braking perfor-
mance or vehicle stability during braking may occur. It
will take you longer to stop the vehicle or will make
your vehicle harder to control. You could have a
collision. Have the vehicle checked immediately.
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 cali-
brated torque wrench.
