INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank when
the ignition switch is in the ON/RUN position.
2. 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 to ON/RUN, 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 nones-
sential 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 authorized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”.

7. Seat Belt Reminder Light
When the ignition switch is first turned to ON/
RUN, this light will turn on for four 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 seat
belt remains unbuckled, the Seat Belt Reminder Light
will flash or remain on continuously. Refer to “Occupant
Restraints” in “Things To Know Before Starting Your
Vehicle” for further information.
8. Turn Signal Indicators
The left or right arrow will flash with the corre-
sponding exterior turn signal lights when the turn
signal lever is operated. A chime will sound if the vehicle is
driven more than 1 mile (1.6 km) with either turn signal on.
NOTE:If either indicator flashes at a rapid rate, check
for a defective outside light bulb.
9. Oil Pressure Warning Light
This light indicates low engine oil pressure. The
light should turn on momentarily when the engine is
started; if the bulb does not come on, have the system
checked by an authorized dealer. If the light turns on
while driving, stop the vehicle and shut off the engine as
soon as possible. A chime will sound when this light
turns on.
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.
10. 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.

UNDERSTANDING YOUR INSTRUMENT PANEL 307

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) / Electronic Stability Control (ESC) system.
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 red brake light on is
dangerous. Part of the brake system may have failed.
It will take longer to stop the vehicle. You could have
a collision. Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake System
(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
Light. Immediate repair to the ABS system is required.
308 UNDERSTANDING YOUR INSTRUMENT PANEL

Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for ap-
proximately 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/RUN posi-
tion.
NOTE:This light shows only that the parking brake is
applied. It does not show the degree of brake application.
11. High Beam Indicator
This indicator shows that the high beam head-
lights are on. Push the multifunction control lever
away from you to switch the headlights to high beam.
Pull the lever toward you to switch the headlights back to
low beam. If the driver’s door is open, and the headlights
or park lights are left on, the high beam indicator light
will remain illuminated and a chime will sound.
12. Anti-Lock Brake (ABS) Light
After the ignition is turned on, the Anti-Lock
Brake System (ABS) light illuminates to indicate
function check at vehicle startup. If the light remains on
after startup or comes on and stays on at road speeds, it
may indicate that the ABS has detected a malfunction or
has become inoperative. The system reverts to standard
non-anti-lock brakes.
If both the Brake Warning Light and the ABS Warning
Light are on, see an authorized dealer immediately. Refer
to “Anti-Lock Brake System” in “Starting And
Operating”.

13. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, 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.
14. Rear Axle Lock Indicator — If Equipped
This light indicates when the rear axle lock has
been activated.
15. Tachometer
Indicates the engine speed in revolutions per minute
(RPM x 1000).
CAUTION!
Do not operate the engine with the tachometer
pointer in the red area. Engine damage will occur.
16. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is a part of
an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission con-
trol systems. The light will illuminate when the ignition
is in the ON position before engine start. If the bulb does
not come on when turning the key from OFF to ON/
RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas cap,
poor quality fuel, etc., may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.
310 UNDERSTANDING YOUR INSTRUMENT PANEL

When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal

operating conditions. This can cause a fire if you
drive slowly or park over flammable substances such
as dry plants, wood, cardboard, etc. This could result
in death or serious injury to the driver, occupants or
others.
17. Coolant Temperature Warning Light
This light warns of an overheated engine condi-
tion. If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is on, turn it
off. Also, shift the transmission into NEUTRAL and idle
the vehicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service.

NOTE:As the coolant temperature gauge approaches
#H,#this indicator will illuminate and a single chime will
sound. Further overheating will cause the temperature
gauge to pass#H.#In this case, a continuous chime will
sound, until the engine is allowed to cool or the 4 minutes
duration is expired, whichever come first.
18. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
19. 4WD Indicator Light — If Equipped
This light alerts the driver that the vehicle is in
the four-wheel drive mode, and the front and
rear driveshafts are mechanically locked to-
gether forcing the front and rear wheels to
rotate at the same speed.
20. 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.
21. 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.

26. Hill Decent Indicator
This indicator shows when the Hill Descent
Control (HDC) feature is turned on. The lamp
will be on solid when HDC is armed. HDC can
only be armed when the transfer case is in the
“4WD LOW” position and the vehicle speed is less then
30 mph (48 km/h). If these conditions are not met while
attempting to use the HDC feature, the HDC indicator
light will flash on/off.
27. Cruise Indicator
This indicator shows when the electronic speed
control system is turned on.
28. 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.
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
