ness, for example in tunnels, in twilight or if
there is precipitation.
General information
A blue sky with the sun low on the horizon can
cause the lights to be switched on.

System limits
The automatic headlamp control cannot serve
as a substitute for your personal judgment of
lighting conditions.
E.g. the sensors are unable to detect fog or
hazy weather. To avoid safety risks under
these conditions, you should always switch on
the lights manually.
Daytime running lights
General information Position of switch:
, ,
The daytime running lights light up when the
ignition is switched on. After the ignition is
switched off, the parking lights light up in posi‐

vate the daytime running lights.
On the Control Display:
1."Settings"2."Lighting"3."Daytime running lamps"
Settings are stored for the profile currently
used.
Adaptive Light Control
The concept Adaptive Light Control is a variable headlight
control system that enables dynamic illumina‐
tion of the road surface.
General information
Depending on the steering angle and other pa‐
rameters, the light from the headlamp follows
the course of the road.
To avoid blinding oncoming traffic, the Adap‐
tive Light Control does not swivel to the driv‐
er's side when the vehicle is at a standstill.
Depending on the equipment version, Adap‐
tive Light Control consists of one or several
systems:▷Cornering light, refer to page 102.▷Self-leveling headlights, refer to page 102.
Activating
Position of switch
with the ignition
switched on.
Cornering lights
The cornering lights are automatically
switched on depending on the steering angle
or the use of turn signals.
When driving in reverse, the cornering lights
may be automatically switched on regardless
of the steering angle.
Self-leveling headlights
The self-leveling headlights compensate for
acceleration and braking operations in order
not to blind the oncoming traffic and to achieve
optimum illumination of the roadway.
Malfunction
A Check Control message is displayed.
Adaptive Light Control is malfunctioning or has
failed. Have the system immediately checked
by a dealer’s service center or another quali‐
fied service center or repair shop.
High-beam Assistant
The concept The high-beam Assistant detects other traffic
participants early on and automatically
switches the high beams on or off depending
on the traffic situation. The assistant ensures
that the high beams are switched on, when‐
ever the traffic situation allows. In the low
Seite 102ControlsLights102
Online Edition for Part no. 01 40 2 969 976 - II/16
speed range, the high beams are not switched
on by the system.
General information The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, for example, in towns
and cities.
The driver can intervene at any time and switch
the high beams on and off as usual.
Activating1.Depending on the equipment, turn the light
switch into position

2.Press button on the turn signal lever, ar‐
row.
The indicator lamp in the instrument
cluster is illuminated, when the low
beams are switched on.
The high beams are switched on and off auto‐
matically.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams.
Deactivating The High-beam Assistant is deactivated when
manually switching the high beams on and off,
refer to page 75. To reactivate the High-beam
Assistant, press the button on the turn signal
lever.
System limits
The High-beam Assistant cannot serve as a
substitute for the driver's personal judgment of
when to use the high beams. Therefore, man‐
ually switch off the high beams in situations
where required to avoid a safety risk.
The system is not fully functional in the follow‐
ing situations, and driver intervention may be
necessary:▷In very unfavorable weather conditions,
such as fog or heavy precipitation.▷When detecting poorly-lit road users such
as pedestrians, cyclists, horseback riders
and wagons; when driving close to train or
ship traffic; and at animal crossings.▷In tight curves, on hilltops or in depres‐
sions, in cross traffic or half-obscured on‐
coming traffic on highways.▷In poorly-lit towns and cities and in the
presence of highly reflective signs.▷When the windshield behind the interior
mirror is fogged over, dirty or covered with
stickers, etc.
