For 1990-2009 cars

The instrument cluster is centered above the steering column in the instrument panel (I/P). The instrument cluster contains gages and indicator lamps that provide the driver with vehicle performance information. Warning lights come on when there may be or is a problem with one of the vehicle's functions. Some warning lights come on briefly when the vehicle is started to let you know they are working. Gages can indicated when there may be or is a problem with one of the vehicle's functions. Often gages and warning lights work together to let you know when there is a problem with the vehicle.

The instrument cluster includes the following gages:

• | Fuel gage

• | Engine coolant temperature gauge

• | Voltmeter

• | Speedometer

• | Odometer

• | Trip odometer

• | Tachometer

The instrument cluster contains the following indicator lamps:

• | Headlamp high beam symbol

Electric power is directed to the appropriate lamps and gauges of the instrument cluster by a flexible printed circuit. This circuit is attached to the back of the instrument cluster case. Two multiple connectors and the snap-in bulb sockets help to hold the printed circuit to the back of the instrument cluster.

The instrument cluster is non-serviceable, except as noted in this section. The instrument cluster must be replaced as a unit.

When an instrument cluster is replaced, the law requires that the odometer reading of the replacement unit be set to register the same mileage as the prior odometer. If the same mileage cannot be set the law requires that the following actions be performed:

1. Set the replacement odometer to zero.
2. Install a label on the driver's door frame, providing the following information:

• | The previous odometer reading

• | The date of the replacement
