INSTRUMENT CLUSTER

INSTRUMENT CLUSTER DESCRIPTION
1. Malfunction Indicator Light
This light is part of an onboard diagnostic system
which monitors the emissions and engine control
system. If the vehicle is ready for emissions
testing the light will come on when the ignition is first
turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
testing the light will come on when the ignition is first
turned on and remain on for 15 seconds, then blink for 5
seconds, and remain on until the vehicle is started. If the
bulb does not come on during starting, have the condi-
tion investigated promptly.
If this light comes on and remains on while driving, it
suggests a potential engine control problem and the need
for system service.Although your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.
CAUTION!
Prolonged driving with the MIL on could cause
damage to the engine control system. It also could
affect fuel economy and driveability.
If the MIL is flashing, severe catalytic converter
damage and power loss will soon occur. Immediate
service is required.

2. Voltage Gauge
When the engine is running, the gauge indicates
the electrical system voltage. The pointer should
stay within the normal range if the battery is charged. If
the pointer moves to either extreme left or right and
remains there during normal driving, the electrical sys-
tem should be serviced.
NOTE:If the gauge pointer moves to either extreme of
the gauge, the ªCheck Gagesº indicator will illuminate
and a single chime will sound.
3. Turn Signal Indicators
Lights in instrument cluster flash when outside turn
signals are operating.
4. Tachometer
The tachometer indicates engine speed in revolutions per
minute.CAUTION!
Do not operate the engine with the tachometer
pointer at high rpm for extended periods. Engine
damage may occur.
5. Airbag Indicator Light
The indicator lights and remains lit for 6 to 8 seconds
when the ignition is first turned on. If the light stays on,
flickers or comes on while driving, have the airbag
system checked by an authorized dealer.
6. High Beam Indicator
This indicator shows that headlights are on high
beam.
