described on the following pages.

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.
2. Charging System Warning Light This light shows the status of the electrical charg-
ing system. The light should come on for three
seconds when the ignition is first turned ON. If the light
comes back on immediately or comes on while driving, it
means that there is a problem with the charging system
or the battery is low. Also, a chime will sound if the light
comes back on. See your authorized dealer immediately. 3. Front Fog Light Indicator Light — If Equipped

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

6. Front Axle Lock Indicator Light — If Equipped Indicates when the front axle lock has been
activated.

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 Brake Warning Light will “flash” 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 approxi-
mately 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.
12. Anti-Lock (ABS) Warning Light After the ignition is turned on, this light illumi-
nates 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 your authorized dealer immediately.
Refer to “Anti-Lock Brake System” in Section 5 of this
manual.
13. Airbag Warning Light
This indicator lights and remains lit for six to
eight seconds when the ignition is first turned
on. If the light does not come on for six to eight
seconds, stays on or comes on while driving,
have the airbag system checked by an authorized dealer.
