Adaptive Highbeam Assist
You can use this function to set the
headlamps to change between low beam and
high beam automatically. The system
recognizes vehicles with their lights on, either
approaching from the opposite direction or
traveling in front of your vehicle, and
consequently switches the headlamps from
high beam to low beam.
The system automatically adapts the low-
beam headlamp range depending on the
distance to the other vehicle. Once the
system no longer detects any other vehicles,
it reactivates the high-beam headlamps.
The system's optical sensor is located behind
the windshield near the overhead control
panel.
To activate: activate the Adaptive
X
Highbeam Assist function using the on-
board computer (
Turn the light switch to c or Ã.

the low-beam headlamps, the _
indicator lamp in the instrument cluster
lights up.
If you drive faster than approximately
28 mph (45 km/h):
the headlamp range is set automatically
depending on the distance between the
vehicle and other road users.
If you drive faster than approximately
35 mph (55 km/h) and no other road users
are identified:
the high-beam headlamps are switched on
automatically. The K indicator lamp in
the instrument cluster also lights up.
When you drive slower than approximately
30 mph (45 km/h) or if other road users
are identified or if the roads are sufficiently
illuminated:
the high-beam headlamps are switched off
automatically. The K indicator lamp in
the instrument cluster goes out. The _
indicator lamp in the instrument cluster
stays on.
To deactivate: move the combination
X
switch back to its normal position.
The _ indicator lamp in the instrument
cluster goes out.
