Active high beam
Active high beams is a function that uses cam-
era 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. 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 head-
lights 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 automati-
cally switch to low beams.
When active high beams are activated, a white 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 LED 3
headlights*
If the active high beams are equipped with the
auto on/off function 4
, the headlights will return to
high 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 is
based has limitations. If this symbol and the message Active
High Beam Temporarily unavailable is displayed in the instru-
ment panel, switching between high
and low beams must be done manually. The light-
ing ring on the steering wheel lever can remain in
the position. 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 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
symbol will
be displayed.
WARNING Automatic high beam is an aid in using the
best possible light based on prevailing condi-
tions.
The driver is always responsible for manually
switching between high and low beam when
traffic situations or weather conditions require
this.

help provide maximum illumination in curves and
intersections. Depending on equipment level,

activated (right).
Active Bending Lights follow the movement of
the steering wheel to help provide maximum illu-
mination in curves and intersections, improving
visibility for the driver.
The function is automatically activated when the
engine is started. If a fault is detected in the sys-
tem, the symbol will illuminate in the
instrument panel and a message will be dis-
played. The function is only active in weak daylight or
dark conditions and only when the vehicle is mov-
ing and the low beams are on.
Deactivating/activating the functionThe function is activated as the default factory
setting and can be activated and deactivated in
