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.
•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 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 an accident. 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.

Radial-Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause an accident. Al-
ways use radial tires in sets of four. Never combine
them with other types of tires.
Cuts and punctures in radial tires are repairable only in
the tread area because of sidewall flexing. Consult your
dealer for radial tire repairs.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels above 35 mph (55 km/h).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire dam-
age or failure. A tire could explode and injure
someone. Do not spin your vehicle’s wheels faster
than 35 mph (55 km/h) when you are stuck, and do
not let anyone near a spinning wheel no matter what
the speed.
Tread Wear Indicators
These indicators are narrow strips 1/16 inch (1.6 mm)
thick and are found in the tread pattern grooves.
When the tread pattern is worn down to these treadwear
indicators, the tires should be replaced.

WARNING!
•Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspen-
sion dimensions and performance characteristics,
resulting in changes to steering, handling, and brak-
ing of your vehicle. This can cause unpredictable
handling and stress to steering and suspension com-
ponents. You could lose control and have an accident
resulting in serious injury or death. Use only the tire
and wheel sizes with load ratings approved for your
vehicle.
•Never use a tire smaller than the minimum tire size
listed on your vehicle’s tire label. Using a smaller tire
could result in tire overloading and failure. You
could lose control and have an accident.
•Failure to equip your vehicle with tires having
adequate speed capability can result in sudden tire
failure and loss of vehicle control.
•Overloading your tires is dangerous. Overloading
can cause tire failure. Use tires of the recommended
load capacity for your vehicle - never overload them.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings. Check with your dealer before replacing tires
with a different size.
Alignment and Balance
The suspension components of your vehicle should be
inspected and aligned when needed, to obtain maximum
tire tread life.
Poor suspension alignment may result in:
•reduced tread life;
•uneven tire wear, such as feathering and one-sided
wear;
•vehicle pull to the right or to the left.
220 STARTING AND OPERATING
Page 221 of 352

Tires may also cause the vehicle to pull left or right.
Alignment will not correct this problem. See your dealer
for proper diagnosis of the problem.
Improper alignment will not normally cause vehicle
vibration, which may be a result of tire and wheel
out-of-balance. Proper balancing will reduce vibration
and avoid tire cupping and spotty wear.
TIRE CHAINS
Install chains on rear tires only. Tire chains may be
installed on all models except the Sahara and Rubicon.
Follow these recommendations to guard against damage
and excessive tire and chain wear:
•Use chains on P215/75R15 tires only. P225/75R15,
LT30 x 9.50R15, and LT245/75R16 tires do not provide
adequate clearance.
•Use SAE class “S” tire chains or traction devices only.
•Chains must be the proper size for the vehicle, as
recommended by the chain manufacturer.
•Follow tire chain manufacturer’s instructions for
mounting chains.
•Install chains snugly and tighten after.6 mile (1 km) of
driving.
•Do notexceed 30 mph (48 km/h).
•Drive cautiously, avoiding large bumps, potholes and
extreme driving maneuvers.
TIRE ROTATION RECOMMENDATIONS
Tires on the front and rear axles of vehicles operate at
different loads and perform different steering, handling,
and braking functions. For these reasons, they wear at
unequal rates, and develop irregular wear patterns.
These effects can be reduced by timely rotation of tires.
The benefits of rotation are especially worthwhile with

NOTE:Refer to “Recommended Fluids, Lubricants, and
Genuine Parts” in Section 7 for axle differential lubrica-
tion specifications for towing.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
CAUTION!
Internal damage to the transfer case will occur if a
front or rear wheel lift is used when recreational
towing.
NOTE:The transfer case must be shifted into N (Neu-
tral) for recreational towing.
Shifting Into Neutral (N)
Use the following procedure to prepare your vehicle for
recreational towing.
CAUTION!
It is necessary to follow these steps to be certain that
the transfer case is fully in N (Neutral) before
recreational towing to prevent damage to internal
parts.
1. Depress brake pedal.
2. Shift automatic transmission into N (Neutral) or de-
press clutch pedal on manual transmission.
3. Shift transfer case lever into N (Neutral).
4. Start engine.

HAZARD WARNING FLASHER
The flasher switch is on top of the steering column, just
behind the steering wheel. Depress the switch and both
cluster indicators and all front and rear directional sig-
nals will flash. Depress the switch again to turn Hazard
Warning Flashers off.

Spare Tire Stowage
To remove the spare tire from the carrier, remove the tire
cover, if equipped, and remove the lug nuts with the lug
wrench turning them counterclockwise.NOTE:If you have added aftermarket accessories to the
spare tire mounted carrier, it cannot exceed a gross
weight of 50 lbs (23 kg) including the weight of the spare
tire.
Preparations For Jacking
Park on a firm level surface, avoid ice or slippery areas,
set the parking brakeand place automatic transmission
in P (Park), or manual transmission in R (Reverse). Turn
OFF the ignition.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid being hit when operating the jack
or changing the wheel.
•Turn on the Hazard Warning Flasher.

•Block both the front and rear
of the wheel diagonally oppo-
site of the jacking position.
For example, if changing the
right front tire, block the left
rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.
Jacking Instructions
1. Remove spare tire, jack and tools from stored location.
2. Loosen (but do not remove) the wheel lug nuts by
turning them to the left one turn while the wheel is still
on the ground.
3. Assemble the jack and jacking tools. Connect jack
handle driver to extension, then to lug wrench.4. Operate jack from the front or the rear of the vehicle.
Place the jack under the axle tube, as shown.Do not raise
the vehicle until you are sure the jack is fully engaged.
5. Raise the vehicle by turning the jack screw to the right.
Raise the vehicle only until the tire just clears the surface
