Highbeam Assist
General notes
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 head-
lamps 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
GWARNING
Highbeam Assist does not recognize road
users:
Rwho have no lights, e.g. pedestrians
Rwho have poor lighting, e.g. cyclists
Rwhose 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 prevailing light, vis-
ibility and traffic conditions.
In particular, the detection of obstacles can be
restricted if there is:
Rpoor visibility, e.g. due to fog, heavy rain or
snow
Rdirt on the sensors or anything else covering
the sensors
Activating/deactivating Highbeam
Assist
XTo activate: switch on the Highbeam Assist
function using the on-board computer
(
Ypage 171).
XTurn the light switch to the Ãposition.
XPress the combination switch beyond the
pressure point in the direction of arrow :
(
Ypage 81).
Highbeam Assist is active.
The _ 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 Kindicator 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 adequately lit:
The high-beam headlamps are switched off
automatically. The Kindicator lamp in the
instrument cluster goes out. The _or
indicator lamp in the multifunction
display remains lit.
XTo deactivate: move the combination switch
back to its normal position or move the light
switch to another position.
The _ or
indicator lamp in the
multifunction display goes out.
Headlamps fogged up on the inside
The headlamps may fog up on the inside if there is high atmospheric humidity.
XSwitch on the low-beam headlamps and drive
off.
The level of moisture diminishes, depending
on the length of the journey and the weather
conditions (humidity and temperature).
If the level of moisture does not diminish:
XHave the headlamps checked at a qualified
specialist workshop.

Operation with the remote control
Important information
You can switch the auxiliary heating on/off and
set the operating duration using the remote con-
trol. You can use up to 4 remote control units on
the vehicle. These must be synchronized for the
receiver in your vehicle (
Ypage 110).
The remote control has a maximum range of
approximately 600 meters. This range is
reduced by:
Rsources of interference
Rsolid objects between the remote control and
the vehicle
Rthe remote control being in an unfavorable
position in relation to the vehicle
Rtransmitting from an enclosed space

Operation with the timer
Important safety notes
GDANGER
If a switch-on time has been selected, the
auxiliary heating switches on automatically.
RIf the ventilation is insufficient, poisonous
exhaust gases can collect, in particular car-
bon monoxide. This is the case in enclosed
spaces, for example. There is a risk of fatal
injuries.
RIf highly flammable substances or flamma-
ble materials are nearby, there is a risk of a
risk of fire and explosion.
Always deactivate the preselected switch-on
times if you stop the vehicle in such or similar situations.
Use the timer to:
Ractivate and deactivate immediate heating
mode
Rset up to three switch-on times
Rset the operating duration to between 10 and
120 minutes or to continuous operation
Rset the heating level (preselected tempera-
ture) to a range between 10 and 30
