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‐
tion

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
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.
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.

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 71. 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.
Instrument lighting
Adjusting The parking lights or low beams
must be switched on to adjust
the brightness.
Adjust the brightness with the
thumbwheel.
Interior lights
General information
Depending on the equipment, the interior
lights, footwell lights, entry lamps, and cour‐
tesy lamps are controlled automatically.

The driver must intervene actively when there
is an acute warning. If necessary, the driver is
assisted by a minor automatic braking inter‐
vention in a possible risk of collision.
Acute warnings can also be triggered without
previous forewarning.
Braking intervention
The warning prompts the driver himself/herself
to react. During a warning, the maximum brak‐
ing force is used. Premise for the brake boos‐
ter is sufficiently quick and hard stepping on
the brake pedal. The system can assist with some braking intervention if there is a risk of a
collision. At low speeds vehicles may thus
come to a complete stop.
Manual transmission: During a braking inter‐
vention up to a complete stop, the engine may
be shut down.
The braking intervention is executed only if ve‐
hicle stability has not been restricted, e.g. by
deactivating the DSC Dynamic Stability Con‐
trol.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by ac‐
tively moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.
System limits
Information WARNING
The system can react incorrectly or not
at all due to the system limits. There is risk of
accidents or risk of property damage. Observe
the information regarding the system limits
and actively intervene, if needed.◀
Detection range
The system's detection potential is limited.Thus a system reaction might not come or
might come late.
E. g. the following situations may not be de‐
tected:▷Slow moving vehicles when you approach
them at high speed.▷Vehicles that suddenly swerve in front of
you, or sharply decelerating vehicles.▷Vehicles with an unusual rear appearance.▷Two-wheeled vehicles ahead of you.
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
limited or deactivated, for example, DSC
OFF.▷If the field of view of the camera in the mir‐
ror is dirty or obscured.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop button.▷During calibration of the camera immedi‐
ately after vehicle delivery.▷If there are constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.
Warning sensitivity
The more sensitive the warning settings are,
for example the warning time, the more warn‐
ings are displayed. However, there may also be
an excess of false warnings.

Lane departure warning
The concept Starting at a specific speed, this system alerts
you when the vehicle on streets with lane
markings is about to leave the lane. This
speed, depending on the country version, is
between 35 mph/55 km/h and
45 mph/70 km/h.
When switching on the system below this
speed, a message is displayed in the instru‐
ment cluster.
The steering wheel begins vibrating gently in
the event of warnings. The time of the warning
may vary depending on the current driving sit‐
uation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
Information
WARNING
The system does not release the driver
from the personal responsibility to correctly
assess route and traffic situation. There is risk
of an accident. Adjust the driving style to the
traffic conditions. Watch traffic closely and ac‐
tively intervene in the respective situations. In
the event of a warning, do not unnecessarily
jerk the steering wheel.◀
