Active high beam*
The Active High Beam function detects the
headlamp beams of oncoming traffic or the
rear lights of vehicles in front, and switches
the lighting from main beam to dipped beam.
The lighting returns to main beam when the
incoming light has stopped.
Active high beam - AHB
Active high beam (Active High Beam - AHB) is
a function which uses a camera sensor at the
top edge of the windscreen to detect the
headlamp beams of oncoming traffic or the
rear lights of vehicles in front, and then
switches from main beam to dipped beam.
The function can also take streetlights into
account.
The lighting returns to main beam about a
second after the camera sensor no longer
detects the headlamp beams from oncoming
traffic or the rear lights from vehicles in front.
Activating/deactivating
AHB can be activated when the headlamp
control's knob is in position
(provided
that the function has not been deactivated in
the menu system MY CAR, see MY CAR -
menu options (p. 106)).
Stalk switch and knob for headlamp control in
AUTO position.
The function can start while driving in the
dark when the car's speed is 20 km/h or
higher.
Activate/deactivate AHB by moving the left-
hand stalk switch towards the steering wheel
to the end position and then releasing. Deac-
tivation when main beam is on means that the
lights are reset directly to dipped beam.
Car with analogue combined instrument
panel
When AHB is activated the
symbol illu-
minates in the instrument's information dis-
play.
When main beam has been switched on the
symbol also illuminates in the com-
bined instrument panel.
Car with digital combined instrument panel
When AHB is activated the
symbol
turns white in the instrument's information
display.
When main beam is activated, the symbol
shines blue.
Manual operation
NOTE
Keep the windscreen surface in front of the
camera sensor free from ice, snow, mist
and dirt.
Do not stick or attach anything to the
windscreen in front of the camera sensor
as this may reduce effectiveness or cause
one or more of the systems dependent on
the camera to stop working.
If the message Active main beam
Temporary unavailable Switch manually is
shown in the combined instrument panel's
information display then you have to switch
manually between main and dipped beam.
However, the knob for headlamp control can
still remain in position
. The same
applies if the message
Windscreen sensors
blocked See manual
and the symbol
are shown. The
symbol goes out when
these messages are shown.
AHB may be temporarily unavailable e.g. in
situations with dense fog or heavy rain. When
