such as at an intersection, the automatic en‐
gine stop can be actively prevented.
Preventing an engine stop using the
brake pedal

within one second after the vehicle comes to a
standstill:
▷Immediately after the vehicle comes to a
standstill, briefly press the brake pedal
forcefully.▷Then press the brake pedal with normal
braking force.

tion is deactivated automatically for safety rea‐
sons, as it is detected that no driver is present.
Malfunction
The Auto Start/Stop function no longer
switches off the engine automatically. A Check Control message is displayed. It is possible to
continue driving. Have the system checked by

Speed limit detection
The concept
Speed limit detection
Speed limit detection shows the current maxi‐
mum permitted speed in the instrument clus‐
ter. The camera in the area of the interior mir‐
ror detects traffic signs at the edge of the road
as well as variable overhead sign posts. Traffic
signs with extra symbols for wet road condi‐
tions, etc. are also detected and compared
with the vehicle's onboard data, such as for the
rain sensor, and will be displayed depending
on the situation. The system takes into ac‐
count the information stored in the navigation
system and also displays speed limits present
on routes without signs.
Information WARNING
The system does not release from the
personal responsibility to correctly assess visi‐
bility and traffic situation. There is risk of an ac‐
Seite 86ControlsDisplays86

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 95.
Activating
Position of switch

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.
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
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.
