Activating/deactivating
AHB can be activated when the headlamp con-
trol's knob is in position
(provided that the
function has not been deactivated in the menu
system MY CAR, see MY CAR (p. 115)).
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 approx. 20 km/h
(12 mph) or higher.
Activate/deactivate AHB by moving the left-hand
stalk switch towards the steering wheel to the
end position and then releasing. Deactivation
when main beam is on means that the lights are
reset directly to dipped beam.
When AHB is activated the
symbol turns
white in the instrument's information display.
When main beam is activated, the symbol turns
blue. This also applies for active Xenon head-
lamps if the main beam is partially dimmed, i.e. as
soon as the light beam shines with slightly more
than dipped beam.
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 wind-
screen in front of the camera sensor as this
may reduce effectiveness or cause one or
more of the systems dependent on the cam-
era 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 head-
lamp 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 situa-
tions with dense fog or heavy rain. When AHB
becomes available again, or the windscreen sen-
sors are no longer blocked, the message extin-
guishes and the
symbol illuminates.
WARNING
AHB is an aid for using the optimum beam
pattern when conditions are favourable.
The driver always bears responsibility for man-
ually switching between main and dipped
beam when traffic situations or weather con-
ditions so require.
IMPORTANT
Examples of when manual switching between
main and dipped beam may be required:
•
In heavy rain or dense fog
•
In freezing rain
•
In snow flurries or slush
•
In moonlight
•
When driving in poorly lit built-up areas
•
When the traffic ahead has weak lighting
•
If there are pedestrians on or beside the
road
•
If there are highly reflective objects such
as signs in the vicinity of the road
•
When the lighting from oncoming traffic
is obscured by e.g. a crash barrier
