Instrument Panel Vents

The center and the side vents in the instrument panel can be adjusted up and down and from side to side. The side vents can also be aimed toward the side windows to defog them.

Instrument Compartment

The instrument compartment can be opened by pulling up on the latch handle. The instrument compartment must be removed to gain access to the passenger side airbag module, (if equipped).

Digital Clock

The digital clock is located on the instrument panel above the radio. The clock is capable of an outside temperature display and a 12 hour or a 24 hour display.

Instrument Cluster

The instrument cluster is located above the steering column and in the instrument cluster trim panel. The instrument cluster contains the instruments that provide the driver with vehicle performance information. The instrument cluster contains a speedometer, a tachometer, an odometer, a trip odometer, a temperature gage, a fuel gage, and several indicator lamps.

Speedometer

The speedometer measures the speed of the vehicle in km/h or mph (with km/h). It consists of an instrument cluster gage connected to the vehicle speed sensor on the transaxle output shaft.

Trip Odometer

The trip odometer measures the distance the vehicle has traveled since it was last reset. It consists of an instrument cluster gage connected to the sending unit on the trans- axle output shaft. The trip odometer can be reset to zero at any time so that the driver can record the distance traveled from any starting point.

Fuel Gage

The fuel gage consists of an instrument cluster gage connected to a sending unit in the fuel tank.

The fuel gage indicates the quantity of fuel in the tank only when the ignition is turned to ON or ACC. When the ignition is turned to LOCK or START, the pointer may come to rest at any position.

Temperature Gage

The temperature gage consists of an instrument cluster gage connected to a temperature sensor that is in contact with the circulating engine coolant.

The temperature gage indicates the temperature of the coolant. Prolonged driving or idling in very hot weather may cause the pointer to move beyond the center of the gage. The engine is overheating if the pointer moves into the red zone at the upper limit of the gage.

Tachometer

The tachometer measures the engine’s speed in terms of thousands of revolutions per minute. It consists of an instrument cluster gage connected to a sending unit in the engine control module.

Do not operate the engine in the red zone. Engine damage may occur.

Chime

The chime will sound to bring attention to one or more of the following conditions:

    • The lights are on and the ignition is not in ACC, ON, or START.
    • The ignition key is in the ignition switch when the driver’s side door is open.

Voltage is supplied at all times through the fuse block to power the chime.

Driver Information Center

A driver information center (DIC) is fitted to the instrument panel center. The DIC displays the functions of the heating and ventilation system and the trip computer. The DIC has no serviceable items. If any component fails to function, the module must be replaced.
