INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
The tachometer indicates engine speed in Revolutions
Per Minute (RPM x 1000).
CAUTION!
Do not operate the engine with the tachometer
pointer at high RPM for extended periods. Engine
operation over 3200 RPM can result in significant
damage that will not be covered under the New
Vehicle Limited Warranty.
2. Anti-Lock Brake (ABS) Light This light monitors the Anti-lock Brake System
(ABS). The light will turn on when the ignition
switch is turned to the ON/RUN position and

indicates that the anti-lock portion of the brake system is
not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of anti-lock
brakes. If the ABS light does not turn on when the
ignition switch is turned to the ON/RUN position, have
the light inspected by an authorized dealer.

turned on and remain on, as a bulb check, until the
engine is started. If the vehicle is not ready for emissions
