Active high beams (AHB)*

Updated 2023-06-08

AHB uses a camera at the upper edge of the windshield to detect the headlights of oncoming vehicles or the taillights of a vehicle directly ahead. When this happens, the headlights will automatically switch from high beams to low beams. When the camera no longer detects the headlights/taillights of other vehicles, your headlights will switch back to high beams after several seconds.

To activate AHB:

Turn the headlight control to the position.

The feature will begin functioning if the engine has been running for at least 20 seconds and the vehicle's speed is at least 12 mph (20 km/h).

Switch AHB on or off by pulling the left steering wheel lever rearward (toward the steering wheel) as far as possible and releasing it. If AHB is switched off while the high beams are on, the headlights will change to low beams.

Models with an analog instrument panel

When AHB is activated, the P3/P4-1320--Symbol AHB activated symbol will illuminate in the instrument panel. The high beam indicator ( Symbol helljus - text ) in the instrument panel will also illuminate when the high beams are on.

Models with a digital instrument panel

When AHB is activated, P3/P4-1320--Symbol AHB activated will illuminate as a white symbol in the instrument panel. When the high beams are on, the symbol will change to blue.

Note

Keep the windshield in front of the camera free of ice, snow, dirt, etc.
Do not mount or in any way attach anything on the windshield that could obstruct the camera.

If Active high beam Temporary unavailable Switch manually is displayed in the instrument panel, switching between high and low beams will have to be done manually. However, the light switch can remain in the P3-1220 Symbol AUTO in light switch module position. The same applies if Windscreen Sensors blocked is displayed and the P3/P4-1320-Symbol Vindrutesensorer täckta symbol is displayed. The P3/P4-1320--Symbol AHB activated symbol will go out when these messages are displayed.

AHB may be temporarily unavailable (e.g., in heavy fog or rain). When AHB becomes active again or if the sensors in the windshield are no longer obscured, the messages will disappear and the P3/P4-1320--Symbol AHB activated symbol will illuminate.

Important

In the following situations, it may be necessary to switch between high and low beams manually:

In heavy fog or rain
In blowing snow or slush
In bright moonlight
In freezing rain
In areas with dim street lighting
When oncoming vehicles have dim front lighting
If there are pedestrians on or near the road
If there are reflective objects, such as signs, near the road
When oncoming vehicles' lights are obscured by e.g., fences, bushes, etc.
When there are vehicles on connecting roads
At the top of hills or in dips in the road
In sharp curves
