Automatic High Beam Assist

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 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 deactivated when the headlamp dimmer switch is moved from the neutral position to the high beam or flash to pass positions. Automatic high beam assist can be reactivated by operating the high beam select switch from the neutral position to the high beam position twice within 2 s.

Automatic High Beam Assist System Activation

• Vehicle ON
• Headlamp switch placed in the AUTO position
• Headlamp dimmer switch must be in the neutral position
• Outside lighting conditions must be dark
• Vehicle speed greater than 25 MPH (40 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:

• The system detects approaching traffic headlamps
• The system detects preceding traffic tail lamps
• Ambient light level too high due to towns or twilight situations
• The vehicle's speed drops below 13 MPH (22 km/h)
• Delay

• 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 system.

Automatic High Beam Assist System Deactivation

• Manually operating the headlamp dimmer switch from neutral to high beam position
• Automatic high beam assist is deactivated automatically when the front or rear fog lamps are turned ON

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 panel cluster. When automatic high beam assist is active, the indicator will be illuminated continuously. If the operator deactivates the automatic high beam assist system, the indicator will turn off.
