Launch Control
The concept Launch Control enables optimum acceleration
on surfaces with good traction.
General information
The use of Launch Control causes premature
component wear since this function represents
a very heavy load for the vehicle.
Do not use Launch Control during the break-in,
refer to page 184, period.
To increase vehicle stability, activate DSC
again as soon as possible.
An experienced driver may be able to achieve
better acceleration values in DSC OFF mode.
Requirements

High-beam AssistantThe 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.
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 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 73. 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.

maneuvers or driving over obstacles, for exam‐
ple, curbs, potholes, etc.
Because the possible driving distance de‐
pends on how the vehicle is used during the
trip, the actual distance may be shorter or lon‐
ger depending on the driving speed, road con‐
ditions, external temperature, cargo load, etc.
WARNING
Your vehicle handles differently when a
run-flat tire is damaged and has low or missing
tire inflation pressure, e.g., your lane stability is
reduced when braking, braking distances are
longer and the self-steering properties will
change. There is risk of an accident.
Drive moderately and do not exceed a speed of
50 mph/80 km/h.◀
Final tire failure
Vibrations or loud noises while driving can indi‐
cate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of
the tire could come loose and cause an acci‐
dent.
Do not continue driving. Contact a dealer’s
service center or another qualified service cen‐
ter or repair shop.
Intelligent Safety The concept
Intelligent Safety enables central operation of
the driver assistance system.
Depending on how the vehicle is equipped, In‐
telligent Safety consists of one or more sys‐
tems that can help prevent a imminent colli‐
sion. These systems are active automatically
every time the engine is started using the
Start/Stop button:▷Front-end collision warning, refer to
page 115.▷Pedestrian warning, refer to page 120.Information
WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sys‐
tem may not be output or they may be output
too late or incorrectly. There is risk of an acci‐
dent. Adjust the driving style to the traffic con‐
ditions. Watch traffic closely and actively inter‐
vene in the respective situations.◀
WARNING
Due to system limits, individual functions
can malfunction during tow-starting/towing
with the Intelligent Safety systems activated,
e.g., approach control warning with light brak‐
ing function. There is risk of an accident.

▷If, depending on the vehicle equipment
version, the field of view of the camera in
the mirror or the radar sensor is dirty or ob‐
scured.▷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.
Front-end collision warning
with City Braking function
The concept
The system 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 is done
with limited force and duration.
A camera in the area of the interior mirror con‐
trols the system.
The front-end collision warning is available
even if cruise control has been deactivated.
With the vehicle approaching another vehicle
intentionally, the collision warning and braking
are delayed in order to avoid false system re‐
actions.
General information
The system warns at two levels of an imminent
danger of collision at speeds from approx.
3 mph/5 km/h. Time of warnings may vary with
the current driving situation.
Appropriate braking kicks in at speeds of up to
35 mph/60 km/h.
Detection range
It responds to objects if they are detected by
the system.
Information WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sys‐
tem may not be output or they may be output
too late or incorrectly. There is risk of an acci‐
dent. Adjust the driving style to the traffic con‐
ditions. Watch traffic closely and actively inter‐
vene in the respective situations.◀

Person warning with City
light braking function
The concept The system can help prevent accidents with
pedestrians.
The system issues a warning in the city driving
speed area if there is imminent danger of a col‐
lision with pedestrians and includes a braking
function.
The camera in the area of the interior mirror
controls the system.
General information
With sufficient brightness, the system warns
about possible collision danger with pedes‐
trians starting at approx. 6 mph/10 km/h to ap‐
prox. 35 mph/60 km/h and assists with braking
before a collision.
Under those circumstances it reacts to people
who are within the detection range of the sys‐
tem.
Detection range
The detection area in front of the vehicle is div‐
ided into two areas
▷Central area, arrow 1, directly in front of the
vehicle.▷Expanded area, arrow 2, to the right and
left.
A collision is imminent if pedestrians are lo‐
cated within the central area. A warning is is‐
sued about pedestrians who are located within
the extended area only if they are moving in
the direction of the central area.
Information WARNING
Indicators and warnings do not relieve
the driver from personal responsibility. Due to
system limits, warnings or reactions of the sys‐
tem may not be output or they may be output
too late or incorrectly. There is risk of an acci‐
dent. Adjust the driving style to the traffic con‐
ditions. Watch traffic closely and actively inter‐
vene in the respective situations.◀

End of warningThe warning is canceled in the following situa‐
tions:▷Automatically after approx. 3 seconds.▷When returning to your own lane.▷When braking hard.▷When using the turn signal.
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.◀
Functional limitations
The system may not be fully functional in the
following situations:
▷In heavy fog, rain or snowfall.▷In the event of missing, worn, poorly visi‐
ble, merging, diverging, or multiple lane
markings such as in construction areas.▷When lane markings are covered in snow,
ice, dirt or water.▷In tight curves or on narrow lanes.▷When the lane markings are covered by
objects.▷When driving very close to the vehicle in
front of you.▷When driving toward bright lights.▷When the windshield in front of the interior
mirror is fogged over, dirty or covered with
stickers, etc.▷During calibration of the camera immedi‐
ately after vehicle delivery.Active Blind Spot Detection
The concept
Two radar sensors in the rear bumper monitor
the area behind and next to the vehicle at
speeds above approx. 30 mph/50 km/h.
The system indicates whether there are vehi‐
cles in the blind spot, arrow 1, or approaching
from behind on the adjacent lane, arrow 2.
The lamp in the exterior mirror housing is dim‐
med.
Before you change lanes after setting the turn
signal, the system issues a warning in the sit‐
uations described above.
If there is a risk of collision: the lamp in the ex‐
terior mirror flashes and the steering wheel vi‐
brates.
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‐
cident. Adjust the driving style to the traffic
conditions. Watch traffic closely and actively
intervene in the respective situations.◀
