Ejection MitigationThe head airbag system is designed as an
ejection mitigation countermeasure to reduce
the likelihood of ejections of vehicle occupants
through side windows during rollovers or side
impact events.
Knee airbag The knee airbag supports the legs in a frontal
impact.
Protective action
Airbags are not triggered in every impact situa‐
tion, e.g., in less severe accidents or rear-end
collisions.
Information on how to ensure the optimal
protective effect of the airbags▷Keep at a distance from the airbags.▷Always grasp the steering wheel on the
steering wheel rim, holding your hands at
the 3 o'clock and 9 o'clock positions, to
keep the risk of injury to your hands or
arms as low as possible when the airbag is
triggered.▷There should be no person, animals, or ob‐
jects between an airbag and a person.▷Do not use the cover of the front airbag on
the front passenger side as a storage area.▷Dashboard and windshield on the front
passenger side must stay clear - do not at‐
tach adhesive labels or coverings and do
not attach brackets or cables, e. g., for GPS
devices or' mobile phones.▷Make sure that the front passenger is sit‐
ting correctly, i.e., keeps his or her feet and
legs in the footwell; otherwise, leg injuries
might occur when front airbag is activated.▷Do not place slip covers, seat cushions or
other objects on the front passenger seat
that are not approved specifically for seats
with integrated side airbags.▷Do not hang pieces of clothing, such as
jackets, over the backrests.▷Make sure that occupants keep their heads
away from the side airbag and do not rest
against the head airbag; otherwise, injuries
might occur when airbag is activated.▷Do not remove the airbag system.▷Do not remove the steering wheel.▷Do not apply adhesive materials to the air‐
bag cover panels, do not cover them or
modify them in any way.▷Never modify either the individual compo‐
nents or the wiring in the airbag system.
This also applies to steering wheel covers,
the dashboard, the seats, the roof pillars
and the sides of the roofliner.◀
Even when you follow all instructions very
closely, injury from contact with the airbags
cannot be ruled out in certain situations.
The ignition and inflation noise may lead to
short-term and, in most cases, temporary
hearing impairment in sensitive individuals.
Malfunction, deactivation and after de‐
ploying the airbags
Do not touch the individual components imme‐
diately after the system has been triggered;
otherwise, you may risk burns.
Only have the airbags checked, repaired or dis‐
mantled and the airbag generator scrapped by
the service center or an authorized repair shop
for handling explosives.
Non-professional attempts to service the sys‐
tem could lead to failure in an emergency or
unintentional activation of the airbag - both
may lead to injury.◀
Warnings and information on the airbags are also found on the sun visors.

Warning with braking function
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.
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.
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
DSC Dynamic Stability Control is switched on
and M Dynamic mode MDM is not activated.
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
Detection range
The detection potential of the camera is lim‐
ited.
Thus a warning might not be issued or be is‐
sued late.
E. g. the following situations may not be de‐
tected:▷Partially covered pedestrians.▷Pedestrians that are not detected as such
because of the viewing angle or contour.▷Pedestrians outside of the detection range.▷Pedestrians having a body size less than
32 in/80 cm.
Functional limitations
The system may not be fully functional or may
not be available in the following situations:
▷In heavy fog, rain, sprayed water or snow‐
fall.▷In tight curves.▷If the driving stability control systems are
deactivated, e.g. DSC OFF.▷If the camera viewing field or the front
windshield are dirty or covered.▷Up to 10 seconds after the start of the en‐
gine, via the Start/Stop knob.▷During calibration of the camera immedi‐
ately after vehicle shipment.▷If there is constant blinding effects be‐
cause of oncoming light, e. g., from the sun
low in the sky.▷When it is dark outside.Seite 109SafetyControls109

Lane departure warningThe 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.
Hints Personal responsibility
The system cannot serve as a substitute
for the driver's personal judgment of the
course of the road and the traffic situation.
In the event of a warning, do not jerk the steer‐
ing wheel, as you may lose control of the vehi‐
cle.◀

DSC Dynamic Stability
Control
The concept
DSC prevents traction loss in the power
wheels when driving off and accelerating.
DSC also recognizes unstable vehicle condi‐
tions such as fishtailing or nose-diving. Within
the physical limits DSC helps to keep the vehi‐
cle on a steady course by reducing engine
speed and by applying brakes to the individual
wheels.
Note Adjust your driving style to the situation
An appropriate driving style is always the
responsibility of the driver.
The laws of physics cannot be repealed, not
even with DSC.
Therefore, do not reduce the additional safety
margin by driving in a risky manner.◀

lamp go out.
Indicator/warning lights
When DSC is deactivated, DSC OFF is dis‐
played in the instrument cluster.
The indicator lamp lights up: DSC is
deactivated.
M Dynamic Mode MDM
M Dynamic Mode makes it possible to drive on
a dry roadway with high longitudinal and trans‐
verse acceleration but with limited driving sta‐
bility.
Only in the absolute limit area does the system
intervene for stabilization by reducing the en‐
gine power and by braking interventions on the
wheels. In this driving condition, additional
steering corrections may be necessary.
Limited stabilizing interventions
When M Dynamic Mode is activated, sta‐
bilizing interventions are carried out only to a
reduced extent. You must react yourself; oth‐
erwise, there is the risk of an accident.◀
To increase vehicle stability, activate DSC
again as soon as possible.

Active M differential
The concept The active M differential assures continuously
variable locking of the rear axle differential de‐
pending on the driving situation. This prevents
individual rear wheels from spinning even
when DSC is switched off and in M Dynamic
Mode, so that optimum traction is always as‐
sured in all driving situations.
The driver is responsible adapting his or her
driving behavior to the situation.
Adaptive M chassis The conceptThis system reduces undesirable vehicle mo‐
tion when using a dynamic driving style or trav‐
eling on uneven road surfaces.
The system enhances driving dynamics and
comfort fitting road surface and driving style.

Drive-off assistant This system supports driving off on inclines.
The parking brake is not required.
1.Hold the vehicle in place with the foot
brake.2.Release the foot brake and drive off with‐
out delay.
After the foot brake is released, the vehicle is
held in place for approx. 2 seconds.
Depending on the vehicle load or when a trailer
is used, the vehicle may roll back slightly.
Driving off without delay
After releasing the foot brake, start driv‐
ing without delay, since the drive-off assistant
will not hold the vehicle in place for more than
approx. 2 seconds and the vehicle will begin to
roll back.◀
Servotronic The conceptThe Servotronic varies the steering force re‐
quired to turn the wheels in accordance with
the vehicle speed. At low speeds, the steering
force is strongly supported, i. e. during steer‐
ing, low force is required. As the speed in‐ creases, the assistance of the steering force is
reduced.
Furthermore, the steering force adapts accord‐
ing to the driving program, so that a direct, sporty feel and/or comfortable steering is con‐
veyed.
Programs Steering force setting options:▷"Comfort": low.▷"Sport": medium.▷"Sport Plus": high.
