Speed limit detection
The concept
Speed limit detection
Speed limit detection uses a symbol in the
shape of a traffic sign to display the currently
detected speed limit. The camera in the area of
the interior rearview mirror detects traffic signs
at the edge of the road as well as variable over‐
head sign posts. Traffic signs with extra sym‐
bols for wet road conditions, etc. are also de‐
tected 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 account the information
stored in the navigation system and also dis‐
plays speed limits present on routes without
signs.
Hints Personal judgment
The system cannot serve as a substitute
for the driver's personal judgment of the traffic
situation.
The system assists the driver and does not re‐
place the human eye.◀

mirror.

terior rearview mirror clean and clear.

The system may not be fully functional and
may provide incorrect information in the fol‐
lowing situations:
▷In heavy fog, rain or snowfall.▷When signs are concealed by objects.▷When driving very close to the vehicle in

General information
Position of switch:
, ,
If the driver door is opened with the ignition
switched off, the exterior lighting is automati‐
cally switched off at these switch settings.
Parking lights
Position of switch
: the vehicle's lights
light up on all sides, e.g., for parking.
Do not use the parking lights for extended pe‐
riods; otherwise, they might drain the battery
and it would then be impossible to start the en‐
gine.
When parking, it is preferable to switch on the
one-sided roadside parking lights, refer to
page 92.
Low beams Position of switch
with the ignition
switched on: the low beams light up.
Welcome lights
When the vehicle is parked, leave the switch in
position
or : parking and interior lights
come on briefly when the vehicle is unlocked
depending on the ambient brightness.

ready state is switched off.
Setting the duration

Automatic headlight control
Position of switch
: the low beams are acti‐
vated and off automatically, e.g., in tunnels, in
twilight or if there is precipitation. The indicator
lamp in the instrument cluster lights up.
When emerging from a tunnel during the day,
the low beams are not switched off immedi‐
ately but instead only after approx. 2 minutes.
A blue sky with the sun low on the horizon can
cause the lights to be switched on.
The low beams always stay on when the fog
lights are activated.
Personal responsibility
The automatic headlight control cannot
serve as a substitute for your personal judg‐
ment in determining when to turn the lights on
in response to ambient 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 With the ignition switched on, the daytime run‐
ning lights light up in position
, or
. After the ignition is switched off, the park‐
ing lights light up in position
.
Activating/deactivating
In some countries, daytime running lights are
mandatory, so it may not be possible to deacti‐
vate the daytime running lights.
On the Control Display:1."Settings"2."Lighting"3."Daytime running lamps"
Settings are stored for the profile currently in
use.
Roadside parking lights
The vehicle can be illuminated on one side.
Switching on With the ignition switched off, press the lever
either up or down past the resistance point for
approx. 2 seconds.
Switch off Briefly press the lever to the resistance point in
the opposite direction.
Adaptive Light Control The concept
Adaptive Light Control is a variable headlight
control system that enables dynamic illumina‐
tion of the road surface.
Depending on the steering angle and other pa‐ rameters, the light from the headlight follows
the course of the road.

In tight curves, e.g., on mountainous roads or
when turning, one of the two front fog lights is
switched on as a turning lamp. As a result the
inside of the curve is better lighted.
ActivatingPosition of switch
with the ignition
switched on.
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.
The turning lights are automatically switched
on depending on the steering angle or the use
of turn signals.
When driving in reverse, the turning 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 checked as soon as
possible.
High-beam Assistant
The concept When the low beams are activated, this system
automatically switches the high beams on and
off or suppresses the light in the areas that
blind oncoming traffic. The procedure is con‐
trolled by a camera on the front of the interior
rearview mirror. The assistant ensures that the
high beams are activated whenever the traffic
situation allows. The driver can intervene at
any time and switch the high beams non and
off as usual.
Note Personal responsibility
The High-beam Assistant cannot serve
as a substitute for the driver's personal judg‐
ment of when to use the high beams. There‐
fore, manually reel off the high beams in situa‐
tions where required to avoid a safety risk.◀
Activating1.Depending on the equipment, turn the light
switch into position
or .
2.Press button on the turn signal lever, ar‐
row.
The indicator lamp in the instrument
cluster lights up.
When the low beams are on, the lights are au‐
tomatically brightened or dimmed.
The system responds to light from oncoming
traffic and traffic driving ahead of you, and to
adequate illumination, e.g., in towns and cities.
The blue indicator lamp in the instru‐
ment cluster lights up when the system
switches on the high beams. Depend‐
ing on the version of the system in the vehicle, the high beams may not switch off for oncom‐
ing vehicles, but may only be dimmed in the
areas that blind oncoming traffic. In this case,
the blue indicator light will stay on.

The High-beam Assistant can be switched off
when manually adjusting the light. To reacti‐
vate the High-beam Assistant, press the but‐

System limits
The system is not fully functional in situations such as the following, 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 freeways.▷In poorly-lit towns and cities and in the
presence of highly reflective signs.▷At low speeds.▷When the windshield behind the interior
rearview mirror is fogged over, dirty or cov‐
ered with stickers, etc.Fog lights
