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 simulta-
neously.
8. 4WD Auto Indicator Light – If Equipped The 4WD AUTO indicator light will be illumi-
nated whenever the four-wheel drive mode is
automatically engaged.

9. TOW/HAUL Indicator Light – If EquippedThe TOW HAUL button is located on the
center stack switch bank. This light will illumi-
nate when TOW HAUL mode is selected
10. Exhaust Brake Indicator Light
This light will illuminate when the exhaust brake has
been turned on.
11. 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.
12. 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. 13. 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.

14. Shift Lever Indicator
This display indicator shows the transmission shift lever
selection.
15. High Beam Indicator LightThis 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.
16. 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.
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.
17. Cargo Light
The cargo light will illuminate when the cargo
light is activated by pressing the cargo light
button on the headlight switch.
18. 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.

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.
NOTE: The TPMS telltale is also accompanied by a
“Low Tire” message in the Electronic Vehicle Information
Center (EVIC) screen. Refer to “Starting and Operating/
Tire Pressure Monitor System (TPMS)” in the Owner’s
Manual for further information. 20. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic (OBDII) system which
monitors the emissions and engine control sys-
tem. If the vehicle is ready for emissions testing, the light
will come on when the ignition is first turned on and
remain on, as a bulb check, until the engine is started. If
the vehicle is not ready for emissions testing the light will
come on when the ignition is first turned on and remain
on for 15 seconds, then blink for 5 seconds, and remain
on until the vehicle is started. If the bulb does not come
on during starting, have the condition investigated
promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.
18 UNDERSTANDING YOUR INSTRUMENT PANEL

Although your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and drivability.
21. Airbag Warning Light This light turns on and remains on for six to
eight seconds as a bulb check when the ignition
switch is first turned ON. If the light is not on
during starting, stays on, or turns on while
driving, have the system inspected by an authorized
dealer as soon as possible. 22. Front Fog Light Indicator Light – If Equipped
This indicator will illuminate when the front fog
lights are on.
23. Anti-Lock Brake (ABS) Warning Light This 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.3

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.
24. Seat Belt Reminder LightWhen the ignition switch is first turned ON, this
light will turn on for five to eight seconds as a bulb
check. During the bulb check, if the driver’s seat
belt is unbuckled, a chime will sound. After the bulb
check or when driving, if the driver’s seat belt remains
unbuckled, the seat belt reminder light will flash or
remain on continuously. Refer to Occupant Restraints/
Enhanced Seat Belt Use Reminder System (BeltAlert) in
“Things To Know Before Starting Your Vehicle” in the
Owners Manual for further information. 25. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light –
If Equipped
If the Electronic Stability Program (ESP) /
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 Program
(ESP) becomes active. The “ESP/TCS Indicator Light”
also flashes when TCS is active. Be sure to adapt your
speed and driving to the prevailing road conditions. If
the “ESP/TCS Indicator Light” is on solid, the ESP
system has been turned off by the driver or a temporary
condition exists that will not allow full ESP function.
