Cigar Lighter

The cigar lighter is located in the front portion of the instrument panel. To use the lighter, push it in completely. When the lighter is hot, it will release itself from contact with the heating element. The lighter and the heating element can be damaged if the lighter is not allowed to release itself fully from the heating element.

Ashtray

The ashtray is located in the console. To access the ashtray, pull it out of the ashtray housing. The ashtray lamp will go on when the parking lamps or headlamps are turned ON.

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 in order to defog them.

Glove Box

The glove box can be opened by pulling up on the latch handle. The glove box must be removed in order to gain access to the passenger-side airbag module, if equipped.

Digital Clock

The digital clock is located in the instrument panel, above the radio. The clock is capable of 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 the vehicle performance information. The instrument cluster contains a speedometer, a tachometer, an odometer, a temperature gage, a fuel gage, and several LEDs.

The instrument cluster assembly has no serviceable items except its cover. If any component part fails to function, the instrument cluster assembly must be replaced.

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 the odometer was last reset. It consists of an instrument cluster gage connected to the sending unit on the transaxle 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.

Instrument Cluster Indicator Lamps

The instrument cluster contains indicator lamps that indicate the functioning of certain systems or the existence of potential problems with the operation of the vehicle. LEDs are used to provide illumination. The indicator lamps are not replaceable. If any LED fails to function, the instrument cluster assembly must be replaced.

Tachometer

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

Do no operate the engine in the red zone. Engine damage may occur.

Chime Module

The buzzer is located in the intelligent switching unit. It will sound to bring attention to one or more of the following conditions:

    • The ignition key is in the ignition switch when the driver side door is open and the ignition is in OFF.
    • When there is chime signal input from sensing and diagnostic module (SDM).
    • When vehicle speed exceed over 20 km/h, (if equipped).

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

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.
