Display
Warning of people or animals in
danger
If a collision with a person or an animal de‐
tected in this way is imminent, a warning sym‐
bol appears on the instrument cluster and in
the Head-up Display.
Although both the shape and the heat radiation
are analyzed, false warnings cannot be ruled
out.
Warning area in front of the vehicle
The warning area for the pedestrian warning
consists of two parts:
▷Central area, arrow 1, directly in front of the
vehicle.▷Expanded area, arrow 2, to the right and
left.
With animal warnings, no distinction is made
between the central or expanded area.
The entire area moves along with the vehicle in
the direction of the steering angle and changes
with the vehicle speed. As the vehicle speed
increases, the area becomes longer and wider,
e.g.

The displayed symbol shows the side of the
road on which the person or animal was de‐
tected.
Prewarning
Prewarning for persons is displayed when a
person is detected in the central area immedi‐
ately in front of the vehicle as well as on the left
or right side in the extended area.
Prewarning for animals is displayed when an
animal is detected in the front of the vehicle.
The driver must intervene actively when there
is a prewarning.
Acute warning
Acute warning is displayed if a person or an
animal is detected in direct proximity if front of
the vehicle.
The driver must immediately intervene actively
when there is an acute warning.
Active Protection: if a collision seems to be un‐
avoidable, PreCrash functions are triggered.

Issued warning
Lamp in the exterior mirror
Information stage
The dimmed lamp in the exterior mirror indi‐
cates when there are vehicles in the blind spot
or approaching from behind.
WARNING If the turn signal is set while a vehicle is in the
critical zone, the steering wheel vibrates briefly
and the lamp in the exterior mirror flashes
brightly.
Vehicles with side collision warning: it at
speeds between 45 mph/70 km/h and
130 mph/210 km/h the vibrating steering
wheel is ignored and the lane marking crossed,
the system intervenes with a brief active steer‐
ing intervention and helps to return the vehicle
into the lane. The steering intervention can be
noticed on the steering wheel and can be man‐
ually overridden at any time.
The warning stops when the turn signal is
switched off, or the other vehicle leaves the
critical zone.
Brief flashing of the lamp A brief flashing of the lamp during vehicle un‐
locking serves as system self-test.

Active Protection
The concept
Active Protection prepares occupants and the
vehicle for a possible accident in critical driving
or collision situations.
General information
Active Protection consists of various PreCrash
functions, which can vary depending on the
equipment.
The system is used to detect certain critical
driving situations that might lead to an acci‐
dent. Critical driving situations are:▷Emergency stop.▷Severe understeering.▷Severe oversteering.
Certain functions of several systems can -
within the system limits - lead to Active Pro‐
tection triggering:
▷Collision warning with braking function: de‐
tection of imminent front collisions or auto‐
matic braking intervention.▷Collision warning with braking function or
Night Vision with Dynamic Marker Light:
brake booster.▷Rear collision prevention: detection of im‐
minent rear collisions.
Information
WARNING
The system does not relieve from the
personal responsibility. Due to the system lim‐
its, critical situation could not be detected reli‐
ably or in time. There is risk of an accident. Ad‐
just the driving style to the traffic conditions.
Watch traffic closely and actively interfere in
the respective situations.◀
Function
When the belt is closed, the driver's and pas‐
senger's belt straps are automatically tight‐
ened once after driving away.
In accident-critical situations, the following in‐
dividual functions become active as needed:
▷The front belts are automatically preten‐
sioned.▷Automatic window closing up to a narrow
gap.Seite 160ControlsSafety160

Driving stability control systemsVehicle features and optionsThis 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
systems. The respectively applicable country
provisions must be observed when using the
respective 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.
Adaptive brake assistant In combination with the Active Cruise Control,
this system ensures that the brakes respond
even more rapidly when braking in critical sit‐
uations.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.
The possible holding duration amounts to
2 minutes.
Depending on the vehicle load or when a trailer
is used, the vehicle may roll back slightly.
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.
Information
Adapt your driving style to the situation, for an
appropriate driving style is always the respon‐
sibility 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.

WARNING
When driving with roof load, e.g. 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.◀
Overview
Button in the vehicle
DSC OFF
Indicator/warning lights The indicator lamp flashes: DSC con‐
trols the drive and braking forces.
The indicator lamp lights up: DSC has
failed.
Deactivating/activating DSC
When DSC is deactivated, driving stability is
reduced during acceleration and when driving
in curves.
Stabilizing interventions by the Integral Active
Steering system are only performed by the
rear axle steering.
To increase vehicle stability, activate DSC
again as soon as possible.
Deactivating DSC
Hold the button down until the DSC
OFF indicator lamp is displayed in the
instrument cluster and DSC OFF is displayed.
The DSC system is switched off.
The steering and, depending on the equip‐
ment, suspension are tuned for sporty driving.
Activating DSC Press button.
DSC OFF and the DSC OFF indicator
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.
DTC Dynamic Traction
Control
The concept The DTC system is a version of the DSC where
forward momentum is optimized.
The system ensures maximum headway on
special road conditions or loose road surfaces,
e.g., unplowed snowy roads, but with some‐
what limited driving stability.
Activating the Dynamic Traction Control DTC
provides maximum 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.Seite 164ControlsDriving stability control systems164
