WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip, and the vehicle could skid.

FOUR–WHEEL DRIVE OPERATION (COMMAND-
TRAC I OR ROCK-TRAC)

wear and damage to the driveline components. Refer to
“Shifting Procedures” in this section for further informa-
tion on shifting into 4H or 4L.
The “4WD Indicator Light” (located in the instrument
cluster) alerts the driver that the vehicle is in four-wheel
drive, and the front and rear driveshafts are locked to-
gether. The light will illuminate when the transfer case is
shifted into the 4H position.
NOTE:Do not attempt to shift when only the front or rear
wheels are spinning. The transfer case is not equipped with
a synchronizer, and the front and rear driveshaft speeds
must be equal for a shift to take place. Shifting while the
front or rear wheels are spinning at different speeds can
cause damage to the transfer case.
When operating your vehicle in 4L, the engine speed will
be approximately three times (four times for Rubicon
models) that of the 2H or 4H positions at a given road
speed. Take care not to overspeed the engine.
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type, and circumference on each wheel.
Any difference will adversely affect shifting and cause
damage to the transfer case. Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.

CAUTION!
Prolonged operation of the steering system at the end of
the steering wheel travel will increase the steering fluid
temperature and it should be avoided when possible.
Damage to the power steering pump may occur.
Power Steering Fluid Check
Checking the power steering fluid level at a defined service
interval is not required. The fluid should only be checked
if a leak is suspected, abnormal noises are apparent,
and/or the system is not functioning as anticipated. Coor-
dinate inspection efforts through your authorized dealer.

CAUTION!(Continued)
damage. Tow with all four wheels either ON the
ground, or OFF the ground (using a vehicle trailer).
• Tow only in the forward direction. Towing this
vehicle backwards can cause severe damage to the
transfer case.
• Automatic transmissions must be placed in PARK
for recreational towing.
• Manual transmissions must be placed in gear (not in
Neutral) for recreational towing.
• Before recreational towing, perform the procedure
outlined under “Shifting Into NEUTRAL (N)” to be
certain that the transfer case is fully in NEUTRAL
(N). Otherwise, internal damage will result.
• Towing this vehicle in violation of the above require-
ments can cause severe transmission and/or transfer
case damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.
• Do not use a bumper-mounted clamp-on tow bar on
your vehicle. The bumper face bar will be damaged.
Shifting Into NEUTRAL (N)
Use the following procedure to prepare your vehicle for
recreational towing.

Crossing Obstacles (Rocks And Other High Points)
While driving off-road, you will encounter many types of
terrain. These varying types of terrain bring different types
of obstacles. Before proceeding, review the path ahead to
determine the correct approach and your ability to safely
recover the vehicle if something goes wrong. Keeping a
firm grip on the steering wheel, bring the vehicle to a
complete stop and then inch the vehicle forward until it
makes contact with the object. Apply the throttle lightly
while holding a light brake pressure and ease the vehicle
up and over the object.

Hill Climbing
Hill climbing requires good judgment and a good under-
standing of your abilities and your vehicle’s limitations.
Hills can cause serious problems. Some are just too steep to
climb and should not be attempted. You should always feel
confident with the vehicle and your abilities. You should
always climb hills straight up and down. Never attempt to
climb a hill on an angle.
Before Climbing A Steep Hill
As you approach a hill, consider its grade or steepness.
Determine if it is too steep. Look to see what the traction is on
the hill side trail. Is the trail straight up and down? What is
on top and the other side? Are there ruts, rocks, branches or
other obstacles on the path? Can you safely recover the
vehicle if something goes wrong? If everything looks good
and you feel confident, shift the transmission into a lower
gear with 4L (Low) engaged, and proceed with caution,
maintaining your momentum 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 thehill. 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 fresh
biteinto 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.

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.

1. Remove the spare tire, jack and tools from the storedlocation.
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 the jack handle driver to the extension, then to the lug wrench.
4. Operate the 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 clockwise.Raise the vehicle only until the tire just clears the surface
and enough clearance is obtained to install the spare tire.
Minimum tire lift provides maximum stability.

7. Position the spare wheel/tire on the vehicle and installthe lug nuts with the cone-shaped end toward the
wheel. Lightly tighten the lug nuts clockwise.
