Active high beam
Active high beams is a function that uses camera sensors in the upper edge of thewindshield to detect the headlights ofapproaching vehicles or the taillights of thevehicle directly ahead. When either of theseis detected, the vehicle's headlights will auto-matically switch from high beams to lowbeams.
Active high beams is indicated by the symbol.
This function can be used in dark conditions when the vehicle's speed is approx. 20 km/h(approx. 12 mph) or higher. The function canalso detect street lighting. When the camerasensor no longer detects an approaching vehi-cle or a vehicle ahead, the headlights willreturn to high beams after a second or two.
Activating active high beamsActive high beams can be activated and deac-tivated by turning the lighting ring on the left- side steering wheel lever to position
.
The lighting ring will then return to
.
When active high beams are activated, a white
symbol will be displayed in the instru-
ment panel. When high beams are on, the symbol will be blue. If active high beams are deactivated when the high beams are on, the headlights will auto-matically switch to low beams.
Limitations for active high beamsThe camera sensor on which the function isbased has limitations.
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
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 unavail- able in certain situations, e.g. heavy fog or rain. When active high beams become availa-ble again, or the windshield sensors are nolonger blocked, the message will disappear and the
symbol will be displayed.
WARNING
Automatic high beam is an aid in using the best possible light based on prevailing con-ditions. The driver is always responsible for man- ually switching between high and lowbeam when traffic situations or weatherconditions require this.
