Adaptive Forward Lighting System

WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.

On vehicles equipped with adaptive forward lighting, the headlamps can turn left and right to improve visibility during turns. In order for the adaptive forward lighting system to function, the following conditions must be met:

Ignition ON.
Gear selector in DRIVE.
Headlamp switch in AUTO position.
The ambient light sensor indicating Night.
Vehicle speed greater than 2 km/h (1.3 mph).
The steering wheel is turned greater than 10 degrees to the right or left.

If turning right, the right headlamp turns a maximum of 15 degrees and the left headlamp a maximum of 5 degrees. If turning left, the left headlamp turns a maximum of 15 degrees and the right headlamp a maximum of 5 degrees. If the highbeam headlamps are on, the headlamps sensitivity/speed is reduced by half.

Demo mode can be activated by turning the ignition ON during the following conditions:

Gear selector in PARK.
Headlamp switch in AUTO position.
The ambient light sensor indicating Night.

When the ignition is turned ON during these conditions, the headlamps will cycle outboard and then back to center once. The adaptive forward lighting system is self-contained within the right and left headlamp assemblies. The right headlamp assembly contains the control module that drives the adaptive forward lighting motor for the right and left headlamps via serial data. Both right and left headlamps have no serviceable components with the exception of the headlamp ballast and bulb assemblies.
