### Backup Lamps

The backup lamps are incorporated into the rear combination lamps. The backup lamps operate with the ignition switch in the ON position. Placing either the manual selector lever on automatic transmission equipped vehicles or the gearshift control lever on manual transmission equipped vehicles in R (reverse) closes the backup lamps circuit. When the backup lamps circuit close, the backup lamps turn on. On manual transmission equipped vehicles, the backup lamp switch turns on the backup lamps. On 3-speed automatic transmission equipped vehicles, the park/neutral position (PNP) turns on the backup lamps. On 4-speed automatic transmission equipped vehicles, the transmission range switch turns on the backup lamps.

### High-Mounted Stoplamp

The high-mounted stoplamp consists of 1 bulb. The high-mounted stoplamp is at the top of the rear door window on 4-door models. The high-mounted stoplamp attaches to the spare tire carrier on the rear door on 2-door models.

The high-mounted stoplamp operates in conjunction with the stoplamps when you press the brake pedal.

### Daytime Running Lamps (DRL)

Daytime running lamps (DRL) are standard equipment on all models. There is a DRL indicator on the instrument panel cluster assembly. Operating through the low beams at a lower than normal output, the DRL system operates under the following conditions:

1. When the engine is running
2. When the parking brake is not applied
3. When the light switch is in either the OFF or the parklamp position.

For DRL system diagnosis, refer to Headlights/Daytime Running Lights (DRL) Schematics .

### Headlamps

All models are equipped with composite headlamps. Each composite headlamp consists of 1 halogen bulb, providing both high and low-beam operation, and a headlamp assembly. The bulb is separate from the assembly. Do not re-aim the headlights when replacing the bulb and the entire assembly is not removed from the vehicle.

The headlamp relay 1 and relay 2 control the headlamp operation. The headlamp relays 1 and 2 are mounted on a bracket which is bolted to the blower case.

### Taillamps

The taillamps are on each side of the rear door. Each taillamp consists of a dual filament stoplamp/taillamp bulb and a single filament turn signal and backup bulb. The stoplamp filament lights whenever the stoplamp switch closes. Depressing the brake pedal closes the stoplamp switch. The taillamp filament lights when either the parking lamps or headlamps activate. The turn signal filament lights during the turn signal operation.

### Side Marker Lamps

The side marker lamps are single filament bulbs covered by amber colored lenses. They are operational any time the parking lamps or headlamps activate.

### Ashtray Illumination Lamp

The ashtray illumination lamp lights whenever the parking lamps or the headlamps activate.

### Cigar Lighter Illumination Lamp

The cigar lighter illumination lamp lights whenever the parking lamps or the headlamps activate. The cigar lighter illumination lamp bulb socket attaches to the cigar lighter.

### Dome Lamp

The dome lamp is centered on the roof above the seatbacks of the front seats.

The dome lamp consists of a clear lens, the dome lamp bulb, and a 3 position slide switch. The slide switch has the following 3 detent positions:

• | The left or OFF position

• | The center or ON position

• | The right or DOOR position

The dome lamp will not light with the switch in the left position, regardless of whether any door jamb switch is open or closed.

The dome lamp lights with the dome lamp switch in the right position when any door is open, and the door jamb switch is closed. The lamp remains on until all doors close and the door jamb switches are open.

The dome lamp lights with the switch in the center position, regardless of whether any door jamb switch opens or closes.

### Combination Switch

The combination switch is on the steering column. The combination switch consists of the hazard switch and 2 levers.

The first lever is the light/dimmer/turn signal switch which is on the left side of the steering column.

A twist type knob on the end of the light/dimmer/turn signal switch controls the operation of the parking lamps and the headlamps.

When the parking lamps or the headlamps activate, the following exterior lamps illuminate:

• | The taillamps

• | All side marker lamps

• | The license plate lamps

When either the parking lamps or headlamps are activated, the following interior component lamps illuminate:

• | The instrument panel cluster assembly

• | The heater control unit

• | The radio

• | The cigar lighter

• | The ashtray

• | The manual selector

Move the light/dimmer/turn signal switch (combination lever) forward and rearward in order to control the operation of the dimmer switch. Move the lever up and down in order to control the turn signals. The second lever is the windshield wiper/washer switch and the cruise control mode switch, if equipped. This lever is located on the right side of the steering column.

For a description of the windshield wiper/washer combination lever, refer to Wiper/Washer System Description in Wiper/Washer Systems.

For combination switch removal and installation procedures, refer to Inflatable Restraint Steering Wheel Module Coil Replacement - Off Vehicle in Steering Wheel and Column -- Standard.

### Dimmer Switch Operation

The light/dimmer/turn signal switch (combination lever) controls both the low-beam and high-beam headlamp operations. The combination lever is on the left side of the steering column.

Activate the headlamps and push the turn signal/dimmer switch lever forward into the detent position in order to change the headlamps from low-beam to high-beam operation. Pull the lever back to the center position in order to return the headlamps to the low-beam operation.

With the lighting system in either the OFF, the parklamp, or the low-beam headlamp setting, pull the turn signal/dimmer switch lever rearward in order to illuminate the high-beam headlamps. Release the lever to the center position in order to return the system to the previous setting. This is the flash-to-pass feature.

For combination switch removal and installation procedures, refer to Inflatable Restraint Steering Wheel Module Coil Replacement - Off Vehicle in Steering Wheel and Column -- Standard.

### Hazard Lamps

The hazard switch is a part of the combination switch. The hazard switch is on the upper steering column cover. The hazard switch controls the operation of the hazard lamp circuit.

Press the hazard switch to the ON position in order to cause the turn/hazard relay to disengage the turn signal circuit. This will engage the hazard lamp circuit. The turn/hazard relay mounts on a bracket bolted to the blower case. Engaging the hazard lamp circuit causes both turn indicators in the instrument panel cluster assembly along with all exterior turn signal lamps to flash on and off. The hazard lamp circuit operates regardless of the position of the ignition switch.

Press the hazard switch again in order to return the switch to the OFF position and disengage the hazard lamp circuit. This returns the turn/hazard relay to the turn signal mode.

For combination switch removal and installation procedures, refer to Inflatable Restraint Steering Wheel Module Coil Replacement - Off Vehicle in Steering Wheel and Column -- Standard.

• | The instrument panel cluster assembly

• | The heater control unit

• | The radio

• | The cigar lighter

• | The ashtray

Rotate the illumination controller (2) counterclockwise in order to dim the following component lamps:

• | The instrument panel cluster assembly

• | The heater control unit

• | The radio

• | The cigar lighter

• | The ashtray

Activate the parking lamps or headlamps in order for the instrument panel and instrument panel cluster assembly illumination lamps to illuminate.

For information on illumination controller removal and installation procedures, refer to Instrument Panel Lamp Dimmer Switch Replacement in Instrument Panel, Gauges and Console.

### Turn Signal Operation

The turn/hazard relay and the combination (light/dimmer/turn signal) switch control the turn signal operation.

The turn/hazard relay is mounted on a bracket bolted to the right side of the heater case.

The light/dimmer/turn signal switch lever is on the left side of the steering column. Turn the ignition switch to the ON position in order for the turn signals to operate.

When making a partial turn, such as when changing lanes, the driver has the option of moving the lever to a detent stop. The turn signal indicator continues to flash when the lever occupies this position. The flashing will cancel automatically when the lever releases. The detent position allows the driver to make a lane change or a shallow turn without failing to cancel the turn signal lamp. Move the lever past the detent position to either the upward or downward position in order provide conventional turn signal operation.
