You are requested to intervene by
braking or make an evasive maneu‐
ver.
Prewarning
This warning is issued, for example, when there
is the impending danger of a collision or the
distance to the vehicle ahead is too small.
The driver must intervene actively when there is a prewarning.
Acute warning with braking function
Acute warning in displayed in case of the immi‐
nent danger of a collision when the vehicle ap‐
proaches another object at a high differential
speed.
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 booster
is sufficiently quick and sufficiently hard step‐
ping 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.
The braking intervention can be interrupted by
stepping on the accelerator pedal or by actively
moving the steering wheel.
Object detection can be restricted. Limitations
of the detection range and functional restric‐
tions are to be considered.

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 inches/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 field of view of the camera or the
front windshield are dirty or covered.▷If the driving stability control systems are
deactivated, for example DSC OFF.▷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.▷When it is dark outside.
Brake force display
The concept
▷During normal brake application, the brake
lights light up.▷During heavy brake application, the flash‐
ers light up in addition.
PostCrash
In the event of an accident, the system can
bring the car to a halt automatically without in‐
tervention by the driver in certain situations.
This can reduce the risk of a further collision
and the consequences thereof.
Depressing the brake pedal can cause the vehi‐
cle to brake harder. This interrupts automatic
braking. Destepping on the gas pedal also in‐
terrupts automatic braking.
After coming to a halt, the brake is released au‐
tomatically. Secure the vehicle against rolling.

Driving stability control systemsVehicle features and op‐
tions
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and sys‐
tems. The respectively applicable country provi‐
sions must be observed when using the respec‐
tive features and systems.
Anti-lock Braking System
ABS
ABS prevents locking of the wheels during
braking.
The vehicle contains its steering power even
during full brake applications, thus increasing
active safety.
ABS is operational every time you start the en‐
gine.
Brake assistant
When you apply the brakes rapidly, this system
automatically produces the greatest possible
braking force boost. It reduces the braking dis‐
tance to a minimum during emergency stop.
This system utilizes all of the benefits provided
by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the emergency stop.DSC Dynamic Stability
Control
The concept
Dynamic Stability Control detect for example
the following unstable driving conditions:▷Fishtailing, which can lead to oversteering.▷Loss of traction of the front wheel, which
can lead to understeering.
Within the physical limits, the system helps to
keep the vehicle on a steady course by reduc‐
ing engine speed and by applying brakes to the
individual wheels.
Information The system does not relieve the driver from his
responsibility to adjust his driving style accord‐
ing to the situation.
Therefore, adjust the driving style according to
the situation and do not reduce the additional
safety margin by driving in a risky manner.
WARNING
When driving with roof load, for example
with roof-mounted luggage rack, driving safety
may not be ensured in driving-critical situations
due to the elevated center of gravity. There is
risk of accidents or risk of property damage. Do
not deactivate Dynamic Stability Control DSC
when driving with roof load. ◀
Indicator/warning lights The indicator lamp flashes: DSC controls
the drive and braking forces.
The indicator lamp lights up: DSC has
failed.

lamp go out.
Indicator/warning lights
When DSC is deactivated, DSC OFF is displayed
in the instrument cluster.
The indicator lamp lights up: DSC is de‐
activated.
Automatic activation When DSC is deactivated, automatic activation
occurs in the following situations:▷The vehicle has a flat tire.▷When activating cruise control in TRACTION
or DSC OFF mode.
DTC Dynamic Traction
Control
The concept
DTC is a version of the DSC where forward mo‐
mentum is optimized.
The system ensures maximum headway on
special road conditions, for example unplowed
snowy roads or loose road surfaces, but with
somewhat limited vehicle stability.
When DTC is activated, the vehicle has maxi‐
mum traction. Driving stability is limited during
acceleration and when driving in curves.
Therefore drive with appropriate caution.
You may find it useful to briefly activate DTC
under the following special circumstances:▷When driving in slush or on uncleared,
snow-covered roads.▷When freeing vehicle from deep snow or
driving off from loose grounds.▷When driving with snow chains.

Performance Control
Performance Control enhances the agility of the
vehicle.
To increase maneuverability, with a corre‐
spondingly sporty driving style, wheels are
braked individually.
