WARNING! (Continued)
•Check mounting of mats on a regular basis. Al-
ways properly reinstall and secure floor mats that
have been removed for cleaning.
•Always make sure that objects cannot fall into the
driver foot well while the vehicle is moving.
Objects can become trapped under the brake pedal
and accelerator pedal causing a loss of vehicle
control.
•If required, mounting posts must be properly
installed, if not equipped from the factory.
Failure to properly follow floor mat installation or
mounting can cause interference with the brake
pedal and accelerator pedal operation causing loss
of control of the vehicle.
Periodic Safety Checks You Should Make Outside
the Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
90 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

the light is flashing when the engine is running, imme-
diate service is required and you may experience reduced
performance, an elevated/rough idle or engine stall and
your vehicle may require towing. The light will come on
when the ignition is first turned ON and remain on
briefly as a bulb check. If the light does not come on
during starting, have the system checked by an autho-
rized dealer.
16. Electronic Stability Program (ESP) Indicator Light
/ Traction Control System (TCS) Indicator LightThe yellow Electronic Stability Program (ESP)
/ Traction Control System (TCS) indicator light
in the speedometer area illuminates with the
key in the ignition switch turned to the ON/
RUN position. It should go out with the engine running.
The ESP/TCS Indicator Light starts to flash as soon as
the tires lose traction and the ESP system becomes active.
The ESP/TCS Indicator Light also flashes when TCS is
active. If the ESP/TCS Indicator Light begins to flashduring acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions. The “ESP/
TCS Indicator Light” becomes illuminated when the ESP
Off button has been pressed or ESP is only partially
available, caused by lack of engine management or brake
thermal model.
17. Charging System Light
This light shows the status of the electrical charg-
ing system. The light should come on when the
ignition switch is first turned ON and remain on briefly
as a bulb check. If the light stays on or comes on while
driving, turn off some of the vehicle’s non-essential
electrical devices or increase engine speed (if at idle). If
the charging system light remains on, it means that the
vehicle is experiencing a problem with the charging
system. Obtain SERVICE IMMEDIATELY. See an autho-
rized dealer.
198 UNDERSTANDING YOUR INSTRUMENT PANEL

Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the engine.
The engine oil level must be checked under the hood.
22. Airbag Warning LightThis light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned ON. If the light is either not on during
starting, stays on, or turns on while driving,
then have the system inspected at an authorized dealer as
soon as possible. Refer to “Occupant Restraints” in
“Things To Know Before Starting Your Vehicle” for
further information.
23. Tachometer
This gauge measures engine revolutions-per-minute
(RPM x 1000). Before the pointer reaches the red area,
ease up on the accelerator to prevent engine damage. 24. Shift Lever Indicator
The Shift Lever Indicator is self-contained within the
instrument cluster. It displays the gear position of the
automatic transmission.
25. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly, when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale when
one or more of your tires is significantly under-inflated.
200 UNDERSTANDING YOUR INSTRUMENT PANEL

Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator iscombined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.
When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale after replacing one or more
tires or wheels on your vehicle, to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly.

UNDERSTANDING YOUR INSTRUMENT PANEL 201

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
26. Odometer / Trip Odometer Display Area
The odometer shows the total distance the vehicle has
been driven. The trip odometer shows individual trip
mileage. Refer to “Trip Odometer Button” for additional
information. NOTE:
U.S. Federal regulations require that upon trans-
fer of vehicle ownership, the seller certify to the pur-
chaser the correct mileage that the vehicle has been
driven. If your odometer needs to be repaired or serviced,
the repair technician should leave the odometer reading
the same as it was before the repair or service. If s/he
cannot do so, then the odometer must be set at zero, and
a sticker must be placed in the door jamb stating what the
mileage was before the repair or service. It is a good idea
for you to make a record of the odometer reading before
the repair/service, so that you can be sure that it is
properly reset, or that the door jamb sticker is accurate if
the odometer must be reset at zero.

STARTING AND OPERATING 291

The electronically shifted transfer case is designed to be
driven in the two-wheel drive position (2WD) for normal
street and highway conditions (dry hard surfaced roads).
When additional traction is required, the transfer case
4WD LOCK position can be used to lock the front and
rear driveshafts together and force the front and rear
wheels to rotate at the same speed. This is accomplished
by rotating the transfer case switch to the desired posi-
tion. Refer to “Shifting Procedure” for specific shifting
instructions. The 4WD LOCK position is designed for
loose, slippery road surfaces only.
CAUTION!
•Driving in the 4WD LOCK position on dry hard
surfaced roads may cause increased tire wear and
damage to the driveline components.(Continued)
CAUTION! (Continued)
•Do not attempt to make a shift while only the front
or rear wheels are spinning. Shifting while only
the front or rear wheels are spinning can cause
damage to the transfer case.
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case. Tire rotation schedule should be followed
to balance tire wear.
Since 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.

lower gear than necessary to maintain headway. Over-
revving the engine can spin the wheels and traction will
be lost.
Avoid abrupt downshifts on icy or slippery roads, be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4L or 4LO. Use
first gear and 4L or 4LO for very steep hills.
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 brakes. Restart the engine and shift
to REVERSE. Back slowly down the hill allowing the
compression braking of the engine to help regulate your speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the tires.
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. Always back straight
down a hill in REVERSE gear carefully. Never back
down a hill in NEUTRAL using only the brake.
Remember, never drive diagonally across a hill; always
drive straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain headway by
turning the front wheels slowly left and right. This may
provide a fresh “bite” into the surface and will usually
provide traction to complete the climb.
5
STARTING AND OPERATING 313

Traction Downhill
Shift the transmission into a low gear and the transfer
case to 4L or 4LO range. Let the vehicle go slowly down
the hill with all four wheels turning against engine
compression drag. This will permit you to control the
vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.
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.
314 STARTING AND OPERATING

WARNING! (Continued)
•Always fully apply the parking brake when leav-
ing your vehicle or it may roll and cause damage or
injury. Also, be certain to leave the transmission in
PARK. Failure to do so may cause the vehicle to
roll and cause damage or injury.
CAUTION!
If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
ANTI-LOCK BRAKE SYSTEM
The Anti-Lock Brake System (ABS) is designed to aid the
driver in maintaining vehicle control under adverse
braking conditions. The system operates with a separatecomputer to modulate hydraulic pressure, to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.
All vehicle wheels and tires must be the same size and
type, and tires must be properly inflated, to produce
accurate signals for the computer.
WARNING!
Significant over or under-inflation of tires or mixing
sizes of tires or wheels on the vehicle can lead to loss
of braking effectiveness.
The ABS conducts a low-speed self-test at about 12 mph
(20 km/h). If you have your foot lightly on the brake
while this test is occurring, you may feel slight pedal
movement. The movement can be more apparent on ice
and snow. This is normal.5
