19. Trip Odometer Button
Press and release this button to toggle between the
odometer and trip odometer displays. This button is also
used to reset the trip odometer to 0. While the display is
showing the trip odometer, press and hold the button for
approximately 2 seconds and the display will reset to 0.
20. Odometer/Trip Odometer
The odometer shows the total distance the vehicle has
been driven.
The odometer will ªilluminateº when the driver's door
has been opened, and will remain on for 20 seconds after
exiting the vehicle.
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 the correct mileage can be
determined.The trip odometer shows individual mileage up to 999.9
miles (1 600 km). To switch from odometer to trip
odometer, press the trip odometer button.
21. Anti-Lock (ABS) Warning Light
After ignition is turned on, illuminates to indi-
cate function check at vehicle start-up. If 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 red BRAKE warning light and the amber ABS
warning light are on, see your dealer immediately. Refer
to ªAnti-Lock Brake Systemº in Section 5 of this manual.
22. Brake Warning Light
After ignition is turned on, illuminates to in-
dicate function check at vehicle start-up. Indi-
cates parking brake is applied. If the light stays
on when the parking brake is off, it indicates a possible
brake system fluid leak or low pressure level,see your
authorized dealer immediately.

If the parking brake is applied and the vehicle is in
motion, the red BRAKE warning light will ªflashº and a
chime will sound.
The operation of the BRAKE warning light can be
checked by turning the ignition switch from the OFF
position to the ON position. The light should illuminate
for approximately 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.
23. Low Fuel Warning Light
When the fuel level reaches approximately 2 U.S.
Gallons (7.6L) 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.
24. Fuel Cap Indicator
This symbol indicates the side of the vehicle
where the fuel cap is located.25. Fuel Gauge
The pointer shows the level of fuel in the fuel tank. When
the fuel gauge pointer initially moves to E, for your
safety, approximately 2 U.S. Gallons (7.6L) of fuel remain.
NOTE:When the ignition switch is turned to OFF, the
fuel gauge, voltmeter, oil pressure and temperature
gauges may not show accurate readings. When the
engine is not running, turn the ignition switch to ON to
obtain accurate readings.
ELECTRONIC DIGITAL CLOCK
The clock and radio each use the display panel built into
the radio. A digital readout shows the time in hours and
minutes whenever the ignition switch is in the ON or
ACC position and the time button is pressed.
When the ignition switch is in the OFF position, or when
the radio frequency is being displayed, time keeping is
accurately maintained.

Clock Setting Procedure
1. Turn the ignition switch to the ON or ACC position
and press the time button. Using the tip of a ballpoint pen
or similar object, press either the hour (H) or minute (M)
buttons on the radio.
2. Press the H button to set hours or the M button to set
minutes. The time setting will increase each time you
press a button.
RADIO GENERAL INFORMATION
Radio Broadcast Signals
Your new radio will provide excellent reception under
most operating conditions. Like any system, however, car
radios have performance limitations, due to mobile op-
eration and natural phenomena, which might lead you to
believe your sound system is malfunctioning. To help
you understand and save you concern about these ªap-
parentº malfunctions, you must understand a point or
two about the transmission and reception of radio sig-
nals.
Two Types of Signals
There are two basic types of radio signals... AM or
Amplitude Modulation, in which the transmitted sound
causes the amplitude, or height, of the radio waves to
vary... and FM or Frequency Modulation, in which the
frequency of the wave is varied to carry the sound.
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.

²Dense tree coverage may interrupt reception in the
form of short audio mutes.
²Driving under wide bridges or along tall buildings can
cause intermittent reception.
²Placing objects over or too close to the antenna can
cause signal blockage.
CASSETTE TAPE AND PLAYER MAINTENANCE
To keep the cassette tapes and player in good condition,
take the following precautions:
1. Do not use cassette tapes longer than C-90; otherwise,
sound quality and tape durability will be greatly dimin-
ished.
2. Keep the cassette tape in its case to protect from
slackness and dust when it is not in use.
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.
6. Do not expose the disc to direct sunlight.
7. Do not store the disc where temperatures may become
too high.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being On in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily ªclearº by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
The controls for the heating and ventilation system in this
vehicle consist of three rotary control knobs. These com-
fort controls can be set to obtain desired interior condi-
tions.
NOTE:For the HVAC to operate efficiently and reduce
the possibility of fog build up on the interior of the
windows, the air exhausters should be kept clear at all
times. The air exhausters are the slots located on the rear
tailgate.
