The exterior lighting include the following lamps:

The headlamps are operated when the driver places the headlamp switch in the ON position. If the headlight switch is left in the ON position, after the ignition switch has been turned OFF, the headlights will remain on until turned off or the battery runs dead. With the headlights in the low beam position, the high beams may be momentarily turned on or flashed with the dimmer switch handle. The flash-to-pass feature is accomplished by pulling the dimmer switch handle toward the driver. The headlights may be switched to high beam with the opposite movement of the dimmer switch lever.

Both the RH headlamps and the LH headlamps are supplied battery positive voltage from the LIGHTING fuse in the underhood fuse block. The headlamp switch includes the dimmer switch and the flash-to-pass switch. When the headlamp switch is placed in the ON position, a path to ground is provided. Depending on the position of the high/low beam (dimmer) switch, either the low or high beam circuit will now have power and ground.

When the headlamp dimmer switch handle is pulled toward the driver, the flash-to-pass switch closes and grounds the high beam circuit. Both high beams will remain on until the driver releases the switch handle.

The daytime running lamps (DRL) illuminate the low beam headlights at a reduced intensity. With the headlamp switch placed in the OFF position, the DRLs will operate when the ignition switch is in the RUN position, the gear selector is not in the PARK position and the parking brake is released. Any function that turns on the headlights will cancel DRL operation. DRL operation in Manual Transmission equipped vehicles will occur when the ignition switch is in the RUN position, and the parking brake is released.

In DRL operation, battery voltage is provided to the low beam filaments through the normally open contacts of the DRL relay and the voltage dropping diode circuit. When the ignition is in the RUN position, voltage is applied to the DRL relay and the DRL module. If the parking brake is applied, the DRL module will de-energize and open the relay contacts thus turning off the DRLs. Also momentarily when the engine is started, the DRL relay will de-energize and turn off the DRLs until the engine is started and running. The low beam filaments will operate at 90 percent intensity because of the additional voltage drop across the DRL dropping diode.

The turn signal lamps may only be activated with the ignition switch in the ON position. When the turn signal switch lever is placed in either the left or right hand position, the respective turn signal lamps will flash. The instrument panel cluster (IPC) turn signal indicator, either left or right will also flash.

When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators.

The TURN-B/U fuse in the IP fuse block supplies battery positive voltage to the turn/hazard flasher. When the turn signal switch is placed in either the left or right position, a path to ground is applied through the left or right hand turn circuits. The turn hazard flasher then sends an on-off voltage to either the left turn signal output circuit or the right turn signal output circuit.

When the hazard switch is pressed, the hazard switch contacts close and a path to ground is applied for all of the turn signal input circuits of the turn/hazard flasher. The turn/hazard flasher then supplies battery positive voltage in an on-off flashing pattern to all the turn signal lamps. All the turn signal lamps and both turn indicators illuminate in the same flashing pattern.

The front park lamps, rear tail lamps, and marker lamps, if equipped are turned on when the headlamp switch is placed in the PARK or HEADLAMP position, or anytime the headlights are requested. If the park/tail lights are turned on after the ignition switch has been turned OFF, they will remain on until turned off or the battery runs dead.

The front park lamps, rear tail lamps, and marker lamps, if equipped are energized whenever the headlamp switch is in the PARK or HEADLAMP position. Battery voltage is supplied through the headlamp switch, which in turns distributes voltage to the front park lamps, rear tail lamps, and marker lamps, if equipped.

When the driver presses the brake pedal, all stop lamps will illuminate.

The STOP/HAZ fuse in the IP fuse block supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the brake pedal, the switch contacts close and battery voltage is supplied to the stoplamp relay. The stop lamp relay distributes the voltage to the turn/hazard switch which in turn sends battery voltage to the rear stoplamps. The stop lamp circuits use a dual filament, single bulb turn/stop lamp system.

When the driver selects the REVERSE position, the backup lights illuminate.

A TURN-B/U fuse in the IP fuse block supplies battery positive voltage to the backup lamp switch. The back-up lamp switch is located on the transmission. When the driver places the gear selector lever in the REVERSE position, current will flow from the back-up lamp switch to the backup lamps.
