Your PASS
-Key III system, however, is not working
properly and must be serviced by your dealer. Your
vehicle is not protected by the PASS
-Key III system at
this time.
Fuel Gage
United States Canada
When the indicator nears EMPTY (E), you still have a
little fuel left, but you should get more soon.
If your fuel is low, the warning light near the fuel gage
will go on. See ªLow Fuel Warning Lightº later in
this section.
Your fuel gage tells you about how much fuel you have
left when the ignition is on.

yellowblue
2-101
Here are four things that some owners ask about. All
these things are normal and do not indicate that anything
is wrong with the fuel gage.

At the gas station, the gas pump shuts off before the
gage reads FULL (F).

It takes a little more (or less) fuel to fill up than the
gage reads. For example, the gage reads half full, but
it took more (or less) than half of the tank's capacity
to fill it.

The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate EMPTY (E) when the
ignition is turned off.Low Fuel Warning Light
If your fuel is low, the
warning light next to the
fuel gage will go on and
stay on until you add fuel.
If the warning light is still on after adding fuel, you need
to reset the warning light. To reset the warning light,
turn the ignition to OFF then to ON. If the light stays on,
see your dealer right away.
This light will also come on when you turn on the
ignition, but the engine is not running, to show you it is
working. If it doesn't come on as you start your vehicle,
have it fixed right away.

Setting the Variance
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press both the E/M and
MODE buttons simultaneously for approximately five
seconds. The last entered variance zone number will be
displayed. Press the E/M button until the proper

Press the MODE button to set the new variance zone
and resume normal operation.The display will show all the display segments for half a

Automatic Compass Calibration
The compass is self
-calibrating, which eliminates the
need to manually set the compass. When the vehicle is
new, the calibration process may not be complete. In
these cases the calibration symbol, C, will be displayed
where the compass reading is normally displayed.
To calibrate the compass, in an area free from large
metal objects, make three 360
turns. The calibration
symbol will turn off and the compass reading will be
displayed.
Manual Compass Calibration
If the compass appears erratic and the calibration
symbol does not appear, you must manually put the
compass into the calibration mode.
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press both the E/M and
MODE buttons simultaneously for at least 10 seconds
until the calibration symbol appears. Release both
buttons and complete three 360
turns in an area free
from large metal objects. The calibration symbol will
turn off and the compass reading will be displayed.

seat passengers can control the temperature and the
amount of air directed to the rear of the vehicle. The
amount of air directed to the rear of the vehicle can also
be adjusted using the front control for the rear fan.

Playing a Cassette Tape
Your tape player is built to work best with tapes that are
up to 30 to 45 minutes long on each side. Tapes longer
than that are so thin they may not work well in this
player. If a tape is inserted when the ignition is on but
the radio is off, the tape will begin playing. A tape
symbol is shown in the center of the graphic display
whenever a tape is inserted. When a tape is active, the
tape symbol will be accompanied by a direction arrow.
While the tape is playing, use the VOL, AUTO TONE,
BAL, FADE, BASS and TREB controls just as you do
for the radio. Other controls may have different

arrow blinks during PREV or SEEK operation. The
sound will mute during PREV or SEEK operation. Press
this button or one of the SEEK arrows again to return to
normal play.
