You can use this function to set the
headlamps to change betwee
nlow 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.
Switching Adaptive Highbeam Assist
on/off X
To activate: activate the Adaptive
Highbeam Assist function using the on-
board computer (Y page 204).
X Turn the light switch to 0005.
X Press the combination switch beyond the
pressure point in the direction of arrow 0003
(Y page 108).
The 0002 indicator lamp in the
multifunction display lights up if it is dark
and the light sensor activates the low-beam
headlamps.
If you drive at speeds above 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 are driving at speeds above
approximately 35 mph (55 km/h) and no
other road users have been detected:
the high-beam headlamps are switched on
automatically. The 0009indicator lamp in
the instrument cluster also lights up.
If you drive at speeds below 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
0009indicator lamp in
the instrument cluster goes out. The 0002
indicator lamp in the multifunction display
remains lit.
X To deactivate: move the combination
switch back to its normal position.
The 0002 indicator lamp in the instrument
cluster goes out. Headlamps fogged up on the inside
The headlamps may fog up on the inside if
there is high atmospheric humidity.

WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
! Do not depress the accelerator pedal
when starting the engine.
i AMG vehicles: the exhaust flap of the
exhaust system will be checked after every
cold start. Aresulting noise can be heard
during this process.
i During a cold start, the engine runs at
higher speeds to enable the catalytic
converter to reach its operating
temperature. The sound of the engine may
change during this time.
