Overview

Headlamps - Low Series

The low series LED headlamp system consists of 3 low beam (outer) and 2 high beam (inner) non-replaceable Light Emitting Diodes (LEDs). The LED DRL/front parking lamps are integrated into the headlamp assembly and are not individually replaceable.

The low series LED headlamps may be equipped with cornering lamp Light Emitting Diodes (LEDs) right below the headlamp LED DRL/front parking lamps. Depending on the inputs received (steering wheel angle and vehicle speed for example), the top mounted headlamp LED control module illuminates the cornering lamp Light Emitting Diodes (LEDs) to improve nighttime visibility around curves. The cornering lamps are only activated when the headlamp switch is in the AUTOLAMPS position.

When the LH steering column multifunction switch is pulled briefly, the high beam Light Emitting Diodes (LEDs) briefly illuminate for the flash-to-pass function. If the LH steering column multifunction switch is pushed into the high beam position, the high beam Light Emitting Diodes (LEDs) illuminate until the LH steering column multifunction switch is returned to the center position.

The low series LED headlamps may be equipped with cornering lamp Light Emitting Diodes (LEDs) right below the headlamp LED DRL/front parking lamps. Depending on the inputs received (steering wheel angle and vehicle speed for example), the top mounted headlamp LED control module illuminates the cornering lamp Light Emitting Diodes (LEDs) to improve nighttime visibility around curves. The cornering lamps are only activated when the headlamp switch is in the AUTOLAMPS position.

The headlamps may be equipped with automatic headlamp leveling. The headlamp beam height is automatically adjusted according to vehicle load, speed, acceleration and braking. Automatic headlamp leveling is activated when the headlamp switch is in the HEADLAMPS or AUTOLAMPS position.

Headlamps - High Series

The high series LED headlamp system consists of multiple non-replaceable Light Emitting Diodes (LEDs) focused through projector lenses. Headlamp low beams illuminate through both lenses. When high beams are selected, the inner lens Light Emitting Diodes (LEDs) increase in brightness. The LED DRL/front parking lamps are integrated into the headlamp assembly and are not individually replaceable.

The high series LED headlamps are equipped with cornering lamp Light Emitting Diodes (LEDs) right below the headlamp LED DRL/front parking lamps. Depending on the inputs received (steering wheel angle and vehicle speed for example), the top mounted headlamp LED control module illuminates the cornering lamp Light Emitting Diodes (LEDs) to improve nighttime visibility around curves. The cornering lamps are only activated when the headlamp switch is in the AUTOLAMPS position.

The high series LED headlamps are equipped with speed dependent lighting. At low speeds, the cornering lamp Light Emitting Diodes (LEDs) illuminate a wide area to improve foreground vision. As vehicle speed increases, the cornering lamp Light Emitting Diodes (LEDs) illuminate a narrower beam that focuses farther ahead of the vehicle to improve vision farther forward. The speed dependent lighting is only activated when the headlamp switch is in the AUTOLAMPS position.

The high series LED headlamps are equipped with a sign based light mode. When the front camera detects a sop or yield sign the cornering lamp Light Emitting Diodes (LEDs) illuminate at full intensity to allow brighter and wider illumination of an intersection. The sign based light mode is only activated when the headlamp switch is in the AUTOLAMPS position.

When the LH steering column multifunction switch is pulled briefly, the high beam Light Emitting Diodes (LEDs) briefly illuminate for the flash-to-pass function. If the LH steering column multifunction switch is pushed into the high beam position, the high beam Light Emitting Diodes (LEDs) illuminate until the LH steering column multifunction switch is returned to the center position.

The headlamps may be equipped with automatic headlamp leveling. The headlamp beam height is automatically adjusted according to vehicle load, speed, acceleration and braking. Automatic headlamp leveling is activated when the headlamp switch is in the HEADLAMPS or AUTOLAMPS position.

DRL

The DRL system illuminates the LED DRL/front parking lamps at full intensity in the headlamp assembly when the ignition is on, the headlamp switch is in the OFF or AUTOLAMPS position and the headlamps have not been turned on by the autolamp system.

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 from 0 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 and the clockspring (vehicles without adaptive steering) or SCCM (vehicles with adaptive steering) mechanically returns the LH steering column multifunction switch to the neutral position and cancels the turn signal.

The front, rear and exterior mirror turn lamps are non-replaceable Light Emitting Diodes (LEDs).

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 a front or rear turn signal lamp is inoperative, the IPC turn lamp indicator fast flashes at approximately 150 times per minute to indicate a LED outage to the driver (the exterior turn lamps continue to flash at approximately 70 times per minute).

The timed on/off cycle for the hazard lamps is approximately 70 times per minute, regardless of bulb or LED outage.

Turn lamps are located in the front fascia, rear lamp assemblies and exterior mirrors.

Parking, Rear and License Plate Lamps

The LED DRL/front parking lamps in the headlamp assembly are used as parking lamps and illuminated at a reduced intensity when the parking lamps or headlamps are activated.

Parking lamps are located in the headlamp assemblies, front fascia (side marker, if equipped), grille emblem (if equipped), rear lamp assemblies, license plate lamps, rear fascia (side marker, if equipped) and in the reverse lamp assembly.

The rear lamp fade control module ramps up the rear parking lamp illumination during approach detection. For more information about approach detection,
Refer to: Handles, Locks, Latches and Entry Systems - Overview (501-14 Handles, Locks, Latches and Entry Systems, Description and Operation).

Front 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.

Rear Fog Lamp

The rear fog lamp can be turned on when the ignition is in ON by placing the headlamp switch in the HEADLAMPS position and pressing the rear fog lamp switch. The rear fog lamp is located in the rear fascia.

Reversing Lamps

When the transmission is placed in REVERSE, the LH and RH reversing lamps are illuminated.

Trailer Lamps

The TRM supplies voltage to the trailer tow stop/turn lamps when the vehicle stop or turn lamps are commanded on.

The BCMC trailer tow park lamp relay supplies voltage to the trailer tow parking lamps when the vehicle parking lamps are commanded on.

The BCMC trailer tow reversing lamps relay supplies voltage to the trailer tow reversing lamps when the vehicle reversing lamps are commanded on.

The TRM provides voltage to the trailer tow connector for trailer battery charging when all of the following are true:

  • The TRM detects that a trailer is connected.
  • The ignition is on and engine is running.
  • A brake pedal application has been detected in the present ignition cycle.
  • The BCM load shed strategy is not active (a message is displayed in the instrument cluster, such as Low Battery Features Temporarily Turned Off or Turn Power Off To Save Battery, to indicate that BCM load shed strategy is active).
