Active high beam
Active high beams is a function that uses cam-era sensors in the upper edge of the windshieldto detect the headlights of approaching vehiclesor the taillights of the vehicle directly ahead.When either of these is detected, the vehicle'sheadlights will automatically switch from highbeams to low beams.
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 anapproaching vehicle or a vehicle ahead, the head-lights will return to high beams.
This function can be used in dark conditionswhen the vehicle's speed is approx. 20 km/h(approx. 12 mph) or higher.
If active high beams are deactivated when thehigh beams are on, the headlights will automati-cally switch to low beams.
When active high beams are activated, a white
symbol will be displayed in the instrumentpanel.
When high beams are on, the symbol will be blue.For LED headlights, this applies even if the highbeams are partially dimmed, i.e. if the headlightsare illuminated with slightly more than low beams.

Vehicles with LED 3
headlights *
If the active high beams are equipped with the
auto on/off function4, the headlights will return tohigh beams a second or so after the camera sen-sor no longer detects the headlights of approach-ing vehicles or the taillights of a vehicle ahead.

Limitations for active high beams
The camera sensor on which the function isbased has limitations.
If this symbol and the message ActiveHigh Beam Temporarilyunavailable is displayed in the instru-ment panel, switching between highand low beams must be done manually. The light-ing ring on the steering wheel lever can remain in
the position. The symbol will go outwhen the message is displayed.
The same applies if this symbol alongwith the message Windscreensensor Sensor blocked, seeOwner's manual is displayed.
Active high beams may be temporarily unavailablein certain situations, e.g. heavy fog or rain. Whenactive high beams become available again, or thewindshield sensors are no longer blocked, the
message will disappear and the symbol willbe displayed.
WARNING
Automatic high beam is an aid in using thebest possible light based on prevailing condi-tions.
The driver is always responsible for manuallyswitching between high and low beam whentraffic situations or weather conditions requirethis.
