Active Blind Spot Detection
The concept
Two radar sensors below 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.
The lamp in the exterior mirror housing flashes
and the steering wheel vibrates.
Hints 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.◀

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.
Antilock Brake 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.
M Drive The conceptIndividual settings can be carried out in two
preassigned configurations for the vehicle.When the engine is started, an efficient driving
state is active by default. M Drive is deacti‐
vated.

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.

Pathway lines▷Pathway lines can be superimposed on the
image of the rearview camera.▷They help you to estimate how much
space is needed when parking and maneu‐
vering on level pavement.▷They are dependent on the current steer‐
ing angle and are continuously adjusted to
the steering wheel movements.
Turning circle lines
▷Turning circle lines can only be superim‐
posed on the rearview camera image to‐
gether with pathway lines.▷They show the course of the smallest pos‐
sible turning radius on a level road.▷Only one turning radius line is displayed af‐
ter the steering wheel is turned past a cer‐
tain angle.Obstacle marking
Obstacle markings can be faded into the image
of the rearview camera.
Their colored margins match the markings of
the PDC. This simplifies estimation of the dis‐
tance to the object shown.

Parking assistant The concept
This system assists the driver in parking paral‐
lel to the road.
Ultrasound sensors measure parking spaces
on both sides of the vehicle.
The parking assistant calculates the best pos‐
sible parking line and takes control of steering
during the parking procedure.
When parking, also take note of the visual and
acoustic information and instructions issued
by the PDC, the parking assistant and the rear‐
view camera and react accordingly.
A component of the parking assistant is the
PDC Park Distance Control, refer to page 122.
Hints
Personal responsibility
Even an active system does not relieve
the driver from personal responsibility while
driving.
Technically the system has its limits, it cannot
independently react to all traffic situations.
Monitor your driving, be on the alert, observe
the vehicle surroundings and other traffic and
react when needed - risk of accident.◀
Changes to the parking space
Changes to the parking space after it was
measured are not taken into account by the system.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
Transporting cargo
Cargo that extends beyond the perimeter
of the vehicle is not taken into account by the
system during the parking procedure.
Therefore, always be alert and ready to inter‐
vene; otherwise, there is the risk of an acci‐
dent.◀
Curbs
The parking assistant may steer the vehi‐
cle over or onto curb if need be.
Therefore, always be alert and ready to inter‐
vene; otherwise, the wheels, tires, or the vehi‐
cle may become damaged.◀
An engine that has been switched off by the
Auto Start Stop function is restarted automati‐
cally when the parking assistant is activated.
Requirements
