Highbeam Assist
General notes You can use this function to set the head-
lamps to change between low beam and high beam automatically. The system recognizes
vehicles with their lights on, either approach-
ing from the opposite direction or traveling in front of your vehicle, and consequently
switches the headlamps from high beam to
low beam.
Once the system no longer detects any other
vehicles, it reactivates the high-beam head-
lamps.
The system's optical sensor is located behind the windshield near the overhead control
panel.
Important safety notes G
WARNING
Highbeam Assist does not recognize road
users:
R who have no lights, e.g. pedestrians
R who have poor lighting, e.g. cyclists
R whose lighting is blocked, e.g. by a barrier
In very rare cases, Highbeam Assist may fail to
recognize other road users who have lights, or
may recognize them too late. In this or similar situations, the automatic high-beam head-
lamps will not be deactivated or will be acti-
vated regardless. There is a risk of an acci-
dent.
Always carefully observe the traffic conditions and switch off the high-beam headlamps in
good time.
Highbeam Assist cannot take into account
road, weather or traffic conditions. Highbeam Assist is only an aid. You are responsible for
adjusting the vehicle's lighting to the prevail-
ing light, visibility and traffic conditions. In particular, the detection of obstacles can
be restricted if there is:
R poor visibility, e.g. due to fog, heavy rain or
snow
R dirt on the sensors or anything else cover-
ing the sensors
Activating/deactivating Highbeam
Assist X
To activate: switch on the Highbeam
Assist function using the on-board com-
puter (Y page 192).
X Turn the light switch to the 0058position.
X Press the combination switch beyond the
pressure point in the direction of arrow 0043
(Y page 94).
Highbeam Assist is active.
The 00CE or indicator lamp in the
multifunction display lights up when it is
dark and the light sensor activates the low-
beam headlamps.
If you are driving at speeds above approx-
imately 22 mph (35 km/h) and no other
road users have been detected:
The high-beam headlamps are switched on
automatically. The 0057indicator lamp in
the instrument cluster also lights up.
If you are driving at speeds below approx-
imately 19 mph (30 km/h), other road
users are recognized or the roads are ade-
quately lit:
The high-beam headlamps are switched off automatically. The 0057indicator lamp in
the instrument cluster goes out. The 00CE
or indicator lamp in the multifunc-
tion display remains lit.
X To deactivate: move the combination
switch back to its normal position or move the light switch to another position.
The 00CE or indicator lamp in the
multifunction display goes out. 96

Headlamps fogged up on the inside
The headlamps may fog up on the inside if
there is high atmospheric humidity.
X Switch on the low-beam headlamps and
drive off.
The level of moisture diminishes, depend-
ing on the length of the journey and the
weather conditions (humidity and temper-
ature).
If the level of moisture does not diminish:

conditioning system optimally.
R Switch on the cooling with air dehumidifi-
cation function. The indicator lamp above
the rocker switch lights up.
R Set the temperature to 72 ‡ (22 †). Only
change the temperature in small incre-
ments.
R Only use the "Windshield defrosting" func-
tion briefly until the windshield is clear
again. R
Only use air-recirculation mode briefly, e.g.
if there are unpleasant outside odors or
when in a tunnel. The windows could oth-
erwise fog up as no fresh air is drawn into
the vehicle in air-recirculation mode.
R Only use the reheat function until the fog-
ged up windows are clear again. 114

midification function on/off
Important information If you switch off the "Cooling with air dehu-
midification" function, the air inside the vehi- cle will not be cooled (in warm weather) or
dehumidified. The windows could fog up morequickly.
The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu- midified according to the temperature selec-
ted.
Condensation may appear on the underside
of the vehicle when in cooling mode. This is
normal and not a sign that there is a malfunc- tion.
