INSTRUMENT CLUSTER DESCRIPTION
1. Voltmeter
Indicates available battery voltage and charging
system operation. The lower red zone shows that
the battery charge may be too low to start the engine.
With the engine running, the normal operating range is
between 11 and 15 volts. Prolonged gage readings be-
tween 9-11 (undercharge) or above 15 (overcharge) indi-
cate possible malfunction of the generator, voltage regu-
lator or battery. See your dealer if such signs occur.
2. Turn Signal Indicator Light
The arrows will flash in unison with the exterior
turn signals, when using the multi-function control
lever. When the hazard warning system is activated, both
the indicator lights will flash simultaneously.
3. Tachometer
Indicates the engine speed in revolutions per minute.
CAUTION!
Do not operate the engine with the tachometer
pointer in the red area. Engine damage will occur.
4. High Beam Indicator Light
This light shows that the headlights are on high
beam. Pull the multi-function control lever to-
wards the steering wheel to switch the headlights from
high to low beam.
5. Airbag Warning Light
This indicator lights and remains lit for 6 to 8
seconds when the ignition is first turned on. If the

7. Oil Pressure Gage
Indicates the engine oil pressure. This gage does
not measure oil level. Pressure varies with engine
speed, temperature, and oil viscosity. Normal oil pressure
will be midway between the lowest and highest limit
marks.
8. Sentry Key Indicator Light Ð If Equipped
Refer to ªSentry Key Immobilizer Systemº in
Section 2 of this manual for more information.
9. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD II which monitors engine and auto-
matic transmission control systems. This light
will illuminate when the ignition is in the ON position
before engine start. If the bulb does not come on when
turning the ignition key from OFF to ON, have the
condition checked promptly.Certain conditions such has a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light after
engine start. The vehicle should be serviced if the light
stays on through several typical driving cycles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the ªMalfunction Indicator
Lightº may flash to alert of 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.
10. Cruise Indicator Light
This indicator lights when the electronic speed
control system is turned ON.
11. Check Gages Warning Light
This light illuminates when the voltmeter, oil
pressure, or temperature gages indicate a reading
130 UNDERSTANDING YOUR INSTRUMENT PANEL

either too high or too low. Examine the gages carefully,
and follow the instructions above for each indicated
problem.
NOTE:When the ignition switch is turned to OFF, the
fuel gage, voltmeter, oil pressure, and temperature gages
will not show any readings. When the engine is not
running, turn the ignition switch to ON to obtain accu-
rate readings.
12. Part Time Indicator Light
This light alerts the driver that the vehicle is in
the PART TIME four±wheel drive mode, and
the front and rear driveshafts are mechanically
locked together forcing the front and rear wheels to rotate
at the same speed.
13. Transmission Over Temperature Warning Light
This light indicates that there is excessive transmis-
sion fluid temperature that might occur with severe
usage such as trailer towing or snow plowing. If this lightcomes on, stop the vehicle and run the engine at idle or
faster, with the transmission in N (Neutral) until the light
goes off.
14. Temperature Gage
Indicates engine coolant temperature. Any read-
ing within the normal range indicates that the
cooling system is operating satisfactorily.
The gage pointer will likely indicate a higher temperature
(above center scale) 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.
If the pointer rises to the 260É (Hot) mark, pull over and
stop the vehicle. Do not turn the engine off. Idle the
vehicle with the air conditioning turned off, until the
pointer drops back into the normal range.

18. Seat Belt Indicator Light
When the ignition switch is first turned ON, this
light will turn on for 5 to 8 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 Warning Light will flash or remain on
continuously. Refer to9Enhanced Driver Seat Belt Re-
minder System (BeltAlertŸ)9in the Occupant Restraints
section for more information.
19. Anti-Lock Warning Light
The amber ABS warning light will come on when
the ignition is first turned on, and stay on briefly
as a bulb check. If the bulb does not come on during
starting, have the bulb repaired promptly. This light also
illuminates to indicate that the Antilock Brake System
self-check is in process 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. In this
case, the system reverts to standard non-antilock brakes.
Turn the engine off and on again to reset the Antilock
Brake System. If the light remains on, see your autho-
rized dealer. If both the red BRAKE and amber ABS
warning lights are on, see your authorized dealer imme-
diately.
20. Fuel Gage
The pointer shows the level of fuel in the fuel tank when
the ignition key is in the ON position. A small arrow
indicates the side of the vehicle where the filler cap (gas
cap) is located.

21. Low Fuel Warning Light
When the fuel level reaches approximately 1.5 U.S.
Gallons (6L) this light will come on and remain on
until fuel is added. The ªLow Fuel Warning Lightº
may turn on and off again, especially during and after
hard braking, accelerations, or turns. This occurs due to
the shifting of the fuel in the tank.
Your vehicle has a programmable electronic feature that
will sound a chime when the ªLow Fuel Warning Lightº
comes on. See the information on ªOverhead Console Ð
Customer Programmable Featuresº in Section 3 to turn
this feature on.
22. Fog Light Indicator Light
This light shows when the fog lamps are on.23. Brake Warning Light
The red BRAKE warning light will come on when
the ignition is first turned on, and stay on briefly
as a bulb check. If the bulb does not come on
during starting, have the bulb repaired promptly. If the
light stays on longer, it may be an indication that the
parking brake has not been released.
If the light remains on when the parking brake is off, it
indicates a possible brake hydraulic system malfunction
or low fluid level. In this case, the light will remain on
until the cause is corrected. If a brake malfunction is
indicated, immediate repair is necessary and continued
operation of the vehicle in this condition is dangerous.

Over Temperature Mode
The transmission electronics constantly monitor the
transmission oil temperature. If the transmission gets too
hot, the transmission will change the way it shifts to help
control the condition. This may result in a slightly
different feeling or response during normal operation in
D (Drive) position. If the transmission becomes hot
enough the O/D OFF indicator light and TRANS OVER
TEMP warning light in the instrument cluster may come
on. After the transmission cools down, it will return to
normal operation.
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops or during accelera-
tion, the clutch automatically and smoothly disengages.NOTE:
²The torque converter clutch will not engage until the
transmission fluid and engine coolant are warm (usu-
ally after 1±3 miles (1.6±4.8 km) of driving). Because
engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into ªOverdriveº when cold. This is
considered a normal condition. Pressing the ªO/D
OFFº switch will show that the transmission is able to
shift into and out of ªOverdrive.º
²If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from P (Park) into any other gear
position.
