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.

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gage reads high, 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 in
the high range, turn the engine off immediately, and
call for service.

The odometer is tamper-resistant.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. There-
fore, 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 trip odometer records distance in miles from when-
ever the ªResetº button is pushed. To switch from the

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.

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.

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.

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.

Electrical Disturbances
Radio waves may pick up electrical disturbances during
transmission. They mainly affect the wave amplitude,
and thus remain a part of the AM reception. They
interfere very little with the frequency variations that
carry the FM signal.
AM Reception
AM sound is based on wave amplitude, so AM reception
can be disrupted by such things as lightning, power lines
and neon signs.
FM Reception
Because FM transmission is based on frequency varia-
tions, interference that consists of amplitude variations
can be filtered out, leaving the reception relatively clear,
which is the major feature of FM radio.

3. Keep the cassette tape away from direct sunlight, heat
and magnetic fields such as the radio speakers.
4. Before inserting a tape, make sure that the label is
adhering flatly to the cassette.
5. A loose tape should be corrected before use. To rewind
a loose tape, insert the eraser end of a pencil into the tape
drive gear and twist the pencil in the required directions.
Maintain your cassette tape player. The head and capstan
shaft in the cassette player can pick up dirt or tape
deposits each time a cassette is played. The result of
deposits on the capstan shaft may cause the tape to wrap
around and become lodged in the tape transport. The
other adverse condition is low or ªmuddyº sound from
one or both channels, as if the treble tone control were
turned all the way down. To prevent this, you should
periodically clean the head with a commercially available
WET cleaning cassette.As preventive maintenance, clean the head about every
30 hours of use. If you wait until the head becomes very
dirty (noticeably poor sound), it may not be possible to
remove all deposits with a simple WET cleaning cassette.
CD/DVD DISC MAINTENANCE
To keep the CD/DVD discs in good condition, take the
following precautions:
1. Handle the disc by its edge; avoid touching the
surface.
2. If the disc is stained, clean the surface with a soft cloth,
wiping from center to edge.
3. Do not apply paper, paper CD labels, or tape to the
disc; avoid scratching the disc.
4. Do not use solvents such as benzine, thinner, cleaners,
or antistatic sprays.
5. Store the disc in its case after playing.
