front of you.▷When driving toward bright lights.▷When the windshield behind the interior
rearview mirror is fogged over, dirty or cov‐
ered by a sticker, etc.▷In the event of incorrect detection by the
camera.▷If the speed limits stored in the navigation
system are incorrect.▷In areas not covered by the navigation sys‐
tem.▷When roads differ from the navigation,
such as due to changes in road routing.▷When passing buses or trucks with a
speed sticker.▷If the traffic signs are non-conforming.▷During calibration of the camera immedi‐
ately after vehicle shipment.Selection lists in the

If the driver door is opened with the ignition
switched off, the exterior lighting is automati‐
cally switched off at these reel 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 reel on the
one-sided roadside parking lights, refer to
page 102.
Low beams Position of switch

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.
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 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. The procedure is controlled by a camera
on the front of the interior rearview mirror. The
assistant ensures that the high beams are acti‐
vated whenever the traffic situation allows. The
driver can intervene at any time and reel the
high beams on and off as usual.

switch into position

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.

ton on the turn signal lever.
System limits 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.◀
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.

Front-end collision warning
Depending on the equipment, the collision
warning system consists of one of the two sys‐
tems:▷Front-end collision warning with City Brak‐
ing function, refer to page 119.▷Front-end collision warning with braking
function, refer to page 116.
Front-end collision warning
with braking function
The concept The ystem can help prevent accidents. If an
accident cannot be prevented, the system will help reduce the collision speed.
The system sounds a warning before an immi‐
nent collision and actuates brakes independ‐
ently if needed.
The automatic braking intervention may be
executed with maximum braking force and for
a brief period only as necessary.
If the vehicle is equipped with Active Cruise
Control with Stop & Go, the front-end collision
warning is controlled via the cruise control ra‐
dar sensor in conjunction with a camera.
The front-end collision warning is available even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally the collision warning is delayed
avoiding false alarm.
Note Personal responsibility
The system does not serve as a substi‐
tute for the driver's personal judgment of the
traffic situation.
Be aware of the traffic situation and the vehi‐
cle's surroundings at all times, otherwise acci‐
dents are still possible despite all warnings.◀

Display If a collision with a person detected in this way
is imminent, a warning symbol appears on the
instrument cluster and in the Head-up Display.
The red symbol is displayed and a sig‐
nal sounds.
With instrument display: The red sym‐
bol is displayed and a signal sounds.
Intervene immediately by braking or make an
evasive maneuver.
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 risk of a
collision. At low speeds vehicles may thus
come to a complete stop.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
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.Seite 123SafetyControls123
