Automatic High Beam Assist

WARNING: This page is about a different car, the 2022 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.

The automatic high beam assist system operates the high beam headlamps ON and OFF automatically when the system is activated and certain conditions are met. The automatic high beam assist system consists of a front view camera module that detects light and is able to identify approaching vehicles on an even, straight road at a distance of greater than 0.4 km (0.25 mi). The front camera module analyzes light color, intensity, and movement. The automatic high beam assist system will turn OFF the high beam headlamps when approaching vehicle headlamps or preceding vehicle taillights are detected by the front camera module. Automatic high beam assist can be momentarily deactivated when the headlamp turn signal/multifunction switch is moved from the neutral position to the high beam or flash to pass positions. Automatic high beam assist can be activated and deactivated by selecting the automatic high beam assist position on the turn signal/multifunction switch.

Automatic High Beam Assist System Activation

Automatic high beam assist must be selected on the turn signal/multifunction switch.
Vehicle ON
Turn signal/multifunction switch placed in the AUTO or low beams ON position
Turn signal/multifunction switch placed in the neutral position
Outside lighting conditions must be dark
Vehicle speed greater than 22 mph (35 km/h)

Automatic High Beam Assist System Operation

The following are conditions that the automatic high beam assist system will turn the high beam headlamps off during operation:

Ambient light level too high due to towns or twilight situations
The vehicle's speed drops below 22 mph (35 km/h)

The following are conditions that the automatic high beam assist system will deactivate the high beam LEDs.

The system detects approaching traffic headlamps
The system detects preceding traffic tail lamps

NOTE:

Automatic High Beam Assist may not operate properly if any of the following conditions exist:

Approaching and preceding vehicles lamps are undetectable due to dirt, snow, road spray, smoke, fog, or any other airborne conditions.
The front camera module is covered with ice, dirt, snow, haze, or is obstructed.
The vehicle is being driven on winding or hilly road conditions which would make any on coming vehicle headlamps undetectable by the automatic high beam assist.

Automatic High Beam Assist System Deactivation

Manually operating the turn signal/multifunction switch from the neutral to high beam position will momentarily deactivate the automatic high beam assist.
Manually operating the automatic high beam assist switch located on the turn signal/multifunction switch to the OFF position
Automatic high beam assist is deactivated automatically when the front or rear fog lamps are turned ON
Automatic high beam assist can be deactivated by selecting the automatic high beam assist position on the turn signal/multifunction switch.

Automatic High Beam Assist System Indicator

The status of the automatic high beam assist system is shown by a green indicator located on the instrument cluster. When automatic high beam assist is active, the indicator will be illuminated continuously. If the driver deactivates the automatic high beam assist system, the indicator will turn off.
