Active high beam

Updated 2023-06-08

Active high beams is a function that uses camera sensors in the upper edge of the windshield to detect the headlights of approaching vehicles or the taillights of the vehicle directly ahead. When either of these is detected, the vehicle's headlights will automatically switch from high beams to low beams.

P5-1617 Stalk with turning ring in AHBC position — Active high beam is enabled by moving the lighting ring on the steering wheel lever to .

P5-1707 Symbol AUTO — Active high beam is enabled by moving the lighting ring on the steering wheel lever to .

The function can also detect street lighting. When the camera sensor no longer detects an approaching vehicle or a vehicle ahead, the headlights will return to high beams.

This function can be used in dark conditions when the vehicle's speed is approx. 20 km/h (approx. 12 mph) or higher.

If active high beams are deactivated when the high beams are on, the headlights will automatically switch to low beams.

When active high beams are activated, a white P5-1507 Symbol AHBC activated symbol will be displayed in the instrument panel.

When high beams are on, the symbol will be blue. For LED headlights, this applies even if the high beams are partially dimmed, i.e. if the headlights are illuminated with slightly more than low beams.

Vehicles with halogen headlights

When the camera sensor no longer detects the headlights of approaching vehicles or the taillights of a vehicle ahead, the headlights will return to high beams after a second or so.

If the active high beams are equipped with the auto on/off function2, the headlights will return to high beams a second or so after the camera sensor no longer detects the headlights of approaching vehicles or the taillights of a vehicle ahead.

Limitations for active high beams

The camera sensor on which the function is based has limitations.

P5-1519 Symbol Active HeadBeamTempUnavailable

If this symbol and the message Active High Beam Temporarily unavailable is displayed in the instrument panel, switching between high and low beams must be done manually. The lighting ring on the steering wheel lever can remain in the P5-1707 Symbol AUTO position. The P5-1507 Symbol AHBC activated symbol will go out when the message is displayed.

The same applies if this symbol along with the message Windscreen sensor Sensor blocked, see Owner's manual is displayed.

Active high beams may be temporarily unavailable in certain situations, e.g. heavy fog or rain. When active high beams become available again, or the windshield sensors are no longer blocked, the message will disappear and the P5-1507 Symbol AHBC activated symbol will be displayed.

Warning

Automatic high beam is an aid in using the best possible light based on prevailing conditions.

The driver is always responsible for manually switching between high and low beam when traffic situations or weather conditions require this.
