INSTRUMENT CLUSTER DESCRIPTION
1. Tachometer
The tachometer indicates engine speed in revolutions per
minute.
CAUTION!
Do not operate the engine with the tachometer
pointer at high RPM for extended periods. Engine
damage may occur.
2. Turn Signal Indicator Light The arrow will flash with the exterior turn signal
when the turn signal lever is operated.
NOTE:
•A continuous chime will sound if the vehicle is driven
more than 1 mile (1.6 km) with either turn signal on.
•Check for an inoperative outside light bulb if either
indicator flashes at a rapid rate.
3. Fuel Gauge
Shows level of fuel in tank when ignition switch is in the
ON position.
4. Temperature Gauge
The temperature gauge shows engine coolant tempera-
ture. Any reading within the normal range indicates that
the engine cooling system is operating satisfactorily.
The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer-
ship for service if your vehicle overheats.
5. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour (MPH/km/h).
6. 4LOW Indicator Light – If Equipped This light alerts the driver that the vehicle is in
the four-wheel drive LOW mode. The front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed. Low range provides a greater
gear reduction ratio to provide increased torque at the
wheels. For vehicles equipped with a premium cluster this indi-
cator will display in the Electronic Vehicle Information
Center (EVIC). Refer to ”Electronic Vehicle Information
Center (EVIC)” in “Understanding Your Instrument
Panel” for further information.
7. 4WD Indicator Light – If Equipped
This light indicates the vehicle is in four-wheel
drive and 4LOCK. 4WD allows all four wheels
to receive torque from the engine simultane-
ously.
8. TOW/HAUL Indicator Light – If Equipped The TOW HAUL button is located on the
center stack switch bank. This light will illumi-
nate when TOW HAUL mode is selected

9. Electronic Stability Control (ESC) Indicator
Light/Traction Control System (TCS) Indicator Light –
If EquippedIf the Electronic Stability Control (ESC)/
Traction Control System (TCS) Indicator Light
begins to flash during acceleration, ease up on
the accelerator and apply as little throttle as
possible. This indicator light starts to flash as soon as the
tires lose traction and the Electronic Stability Control
(ESC) becomes active. The “ESC/TCS Indicator Light”
also flashes when TCS is active. Be sure to adapt your
speed and driving to the prevailing road conditions. If
the “ESC/TCS Indicator Light” is on solid, the ESC
system has been turned off by the driver or a temporary
condition exists that will not allow full ESC function.
10. Exhaust Brake Indicator Light
This light will illuminate when the exhaust brake has
been turned on. 11. Vehicle Security Light — If Equipped
This light will flash at a fast rate for approxi-
mately 15 seconds, when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.
12. Oil Pressure Gauge
The pointer should always indicate some oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate a
lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
13. Odometer/Trip Odometer Button
Press this button to toggle between the odometer and the
trip odometer display. Holding the button in resets the
trip odometer reading when in trip mode.

14. Odometer/Electronic Vehicle Information Center
(EVIC) Display
Odometer
The odometer shows the total distance the vehicle has
been driven. U.S. federal regulations require that upon
transfer of vehicle ownership, the seller certify to the
purchaser the correct mileage that the vehicle has been
driven. Therefore, if the odometer reading is changed
during repair or replacement, be sure to keep a record of
the reading before and after the service so that the correct
mileage can be determined.
The two trip odometers show individual trip mileage. To
switch from odometer to trip odometers, press and
release the TRIP ODOMETER button.
To reset a trip odometer, display the desired trip odom-
eter to be reset then push and hold the button for
approximately two seconds until the display resets.15. Shift Lever Indicator
This display indicator shows the transmission shift lever
selection.
16. High Beam Indicator Light
This indicator shows that headlights are on high
beam. Push the multifunction lever forward to
switch the headlights to high beam, and pull toward
yourself (normal position) to return to low beam.
17. Voltmeter
When the engine is running, the gauge indicates the
electrical system voltage. The pointer should stay within
the normal range if the battery is charged. If the pointer
moves to either extreme left or right and remains there
during normal driving, the electrical system should be
serviced.
18 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of the
cycling operation is controlled by the engine control
module. Post-heat operation can run for several minutes,
and then the electrical system and voltmeter needle will
stabilize.
18. Cargo Light The cargo light will illuminate when the cargo
light is activated by pressing the cargo light
button on the headlight switch.
19. Brake Warning Light This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on, it may indicate that the parking brake is applied, that the brake
fluid level is low, or that there is a problem with the
Anti-Lock Brake System reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS). In this case, the light will remain on until
the condition has been corrected. If the problem is related
to the brake booster, the ABS pump will run when
applying the brake and a brake pedal pulsation may be
felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is

indicated by the “Brake Warning Light,” which will turn
on when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the “Brake Warning Light” on
is dangerous. Part of the brake system may have
failed. It will take longer to stop the vehicle. You
could have an accident. Have the vehicle checked
immediately. Vehicles equipped with the ABS, are also equipped with
Electronic Brake Force Distribution (EBD). In the event of
an EBD failure, the “Brake Warning Light” will turn on
along with the “ABS Warning Light.” Immediate repair
to the ABS system is required.
Operation of the “Brake Warning Light” can be checked
by turning the ignition switch from the OFF position to
the ON position. The light should illuminate for approxi-
mately two seconds. The light should then turn off unless
the parking brake is applied or a brake fault is detected.
If the light does not illuminate, have the light inspected
by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake application.

20. Anti-Lock Brake (ABS) Warning LightThis light monitors the Anti-Lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON position and may
stay on for as long as four seconds.
If the “ABS Warning Light” remains on or turns on while
driving, it indicates that the anti-lock portion of the brake
system is not functioning and that service is required.
However, the conventional brake system will continue to
operate normally if the “Brake Warning Light” is not on.
If the “ABS Warning Light” is on, the brake system
should be serviced as soon as possible to restore the
benefits of anti-lock brakes. If the “ABS Warning Light”
does not turn on when the ignition switch is turned to the
ON position, have the light inspected by an authorized
dealer. 21. Tire Pressure Monitoring Telltale Light – If
Equipped
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.)

UNDERSTANDING YOUR INSTRUMENT PANEL 21

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.
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 is
combined 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.
