INSTRUMENT CLUSTER DESCRIPTIONS
1. Fuel Gauge
The pointer shows the level of fuel in the fuel tank.
2. Charging System LightThis 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 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 authorized dealer.
If jump starting is required, refer to “Jump Starting
Procedures” in “What To Do In Emergencies”. 3. Front Fog Light Indicator — If Equipped
This indicator will illuminate when the front fog
lights are on.
4. Low Fuel Warning Light When the fuel level reaches approximately 2.8 gal
(10.6L) this light will turn on and a single chime
will sound.
5. Speedometer
Indicates vehicle speed.
6. Front Axle Lock Indicator — If Equipped Indicates when the front axle lock has been
activated.
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
266 UNDERSTANDING YOUR INSTRUMENT PANEL

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 IndicatorsThe 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. High Beam Indicator

11. Brake Warning LightThis 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) / 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.
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.
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 start-up. If the light remains on
after start-up 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 Operat-
ing”.

13. Air Bag Warning LightThis 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. 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, the indicator light will
flash continuously and a continuous chime will sound,
until the engine is allowed to cool.

17. Vehicle Security Light — If EquippedThis 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.
18. 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.CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H” and you hear continuous chimes,
turn the engine off immediately and call an autho-
rized dealership for service.
