Overview
Headlamps
The Halogen headlamp system is a quad-beam pattern system that consists of a replaceable low beam halogen bulb and a replaceable halogen bulb for the high beam.
When the LH steering column multifunction switch is pulled briefly, the high beam bulbs briefly illuminate for the flash-to-pass function. If the LH steering column multifunction switch is pushed, the high beam bulbs illuminate until the LH steering column multifunction switch is returned to the center position.
DRL
For vehicles not equipped with daytime running/parking lamp Light Emitting Diodes (LEDs) inside the headlamp assembly, the DRL system illuminates the high beam bulbs at a reduced intensity when the ignition is on and the headlamp switch is in the OFF or AUTOLAMPS position
For vehicles equipped with daytime running/parking lamp Light Emitting Diodes (LEDs) inside the headlamp assembly, the DRL system illuminates the daytime running/parking Light Emitting Diodes (LEDs) in the headlamp assembly at full intensity when the ignition is on and the headlamp switch is in the OFF or AUTOLAMPS position
Autolamps
The autolamp system provides light sensitive automatic on/off control of the exterior lamps. When the ambient lighting is low enough and the headlamp switch is in the AUTOLAMPS position, the exterior parking and low beam lamps illuminate. The autolamp system keeps the exterior lamps on for a preselected period of time after the ignition is turned OFF (20 seconds is the factory default setting). The preselected time is adjustable up to approximately 2 minutes by using the IPC message center controls.
Stoplamps
The stoplamp switch is located on the brake pedal assembly. The rear lamps and high mounted stoplamp are illuminated when the brake pedal is applied.
Turn Signal and Hazard Lamps
The LH steering column multifunction switch has 2 detents for the left turn position and 2 detents for the right turn position. When placed in the first detent and released, the corresponding turn signals flash 3 times and turn off. When the LH steering column multifunction switch is moved to the second detent, the turn signal flashes until the steering wheel is turned in the opposite direction.
When the hazard function is active, all the turn lamps flash on and off.
The timed on/off cycle for turn lamps is approximately 70 times per minute if both the front and rear turn signal lamps operate correctly.
If a front or rear turn signal lamp is inoperative, the turn lamps fast flash the remaining turn lamp(s) approximately 150 times per minute to indicate a bulb outage to the driver.
The timed on/off cycle for the hazard lamps is approximately 70 times per minute, regardless of bulb outage.
Turn lamps are located in the front fascia, rear lamp assemblies and exterior mirrors.
Parking, Rear and License Plate Lamps
If equipped, the front daytime running/parking Light Emitting Diodes (LEDs) in the headlamp assembly are used as parking lamps and illuminated at a reduced intensity when the parking lamps or headlamps are activated.
Front parking lamps are located in the front fascia and side marker lamps are located in the headlamp assemblies.
The rear lamp assembly contains the rear parking/brake lamp bulb. The bulb is a dual filament bulb. The parking lamp operation is not affected by the brake lamp operation.
Rear parking lamps are located in the rear lamp assemblies and also include the LH and RH license plate lamps.
Fog Lamps
The front fog lamps can be turned on when the ignition is in ON, by placing the headlamp switch in any position except OFF and pressing the front fog lamp switch. The front fog lamps are part of the LH and RH turn lamp assemblies mounted in the front fascia.
Reversing Lamps
When the transmission is placed in REVERSE, the LH and RH reversing lamps are illuminated.
The reversing lamp assembly is mounted in the rear fascia.
Trailer Lamps
The TRM supplies voltage to the trailer tow stop/turn lamps when the vehicle stop or turn lamps are commanded on.
The TRM supplies voltage to the trailer tow parking lamps when the vehicle parking are commanded on.
