Dynamic Stability Control,
DSC
Principle DSC prevents the driven wheels losing traction
when you pull away from rest or accelerate.
DSC is also able to detect unstable driving
conditions such as loss of traction at the rear
or vehicle slip over the front wheels. DSC re‐
duces engine output and applies the brakes at
individual wheels, helping, within the limits im‐
posed by the laws of physics, to keep the vehi‐
cle safely on course.
Note Adapt the driving style to the situation as it is
always the driver's responsibility to adapt a
suitable driving style.
Not even DSC can overcome the laws of phys‐
ics.
Do not limit the additional safety afforded by
this system by taking driving risks.

WARNING
When driving with a roof load, for exam‐
ple with a roof rack, the higher centre of gravity
can mean that driving safety is no longer guar‐
anteed in critical driving situations. Danger of
accident or damage to property. Do not deacti‐
vate Dynamic Stability Control DSC when driv‐
ing with a roof load.◀
Overview
Button in the vehicle
DSC OFF button
Indicator and warning lights If indicator light is flashing: DSC is reg‐ulating the acceleration and braking
forces.
If indicator light is illuminated: DSC has failed.
Deactivating DSC: DSC OFF
General Driving stability during acceleration and cor‐
nering is restricted if DSC is deactivated.
To support the driving stability, re-activate
DSC as soon as possible.
Deactivating DSC Press and hold down the button – but for
no longer than approximately 10 seconds
– until the DSC OFF indicator light in the in‐
strument cluster is illuminated and DSC OFF is
displayed.
The DSC system is switched off.
Activating DSC Press the button.
The DSC OFF and DSC OFF indicator
lights are not illuminated.
Indicator and warning lights DSC OFF is displayed in the instrument cluster
when DSC is deactivated.
If indicator light is illuminated: DSC is
deactivated.
M Dynamic Mode
M Dynamic Mode allows driving with higher
longitudinal and transverse acceleration on dry
carriageways, but with restricted drive stability.
Only in the absolute limit of the range does the
system engage for stability purposes by re‐
ducing the engine power and by brakes ap‐
plied to the wheels. In this driving situation, ad‐
ditional steering corrections may be required.
WARNING
With activated M Dynamic Mode stabilis‐
ing engagements are only carried out to a re‐
duced degree. Danger of accident or damage
to property. Adapt to the traffic conditions. Ob‐
serve the traffic situation and intervene actively
if the situation warrants it. Do not move the
steering wheel with unnecessary force in case
of warnings.◀
To support the driving stability, re-activate
DSC as soon as possible.
Activating MDM Press the button briefly.
In the instrument cluster, the indicator
lights MDM and DSC OFF illuminate.Seite 125Driving stability control systemsControls125

This message is operated by pressing the but‐
ton again.
Deactivating MDM
Press the corresponding button 1 or button 2
on the steering wheel again.
M Dynamic Mode and the settings selected
under M Drive are deactivated.
Indicator and warning lights Indicator lights illuminate:
M Dynamic Mode is activated.
DSC indicator light also flashes:
M Dynamic Mode is regulating the driv‐
ing and braking forces.
Indicator lights illuminate:
M Dynamic Mode or DSC has failed.
Active M Differential
Principle The active M Differential blocks the rear axis
transmission steplessly, depending on the
drive situation. In so doing, even with the DSC
switched off and in M Dynamic Mode, spinning
of a single rear wheel is avoided and therefore
optimum traction is provided under all driving
conditions.
The driver is responsible for a driving style ap‐
propriate to the situation.
Adaptive M chassis PrincipleThe system reduces unwanted vehicle move‐
ments when a dynamic driving style is used or
on uneven roads.
Depending on the condition of the road and
the driving style, this enhances driving dynam‐
ics and driving comfort.

Drive-off assistant The system provides support when driving off
on upward inclines. It is not necessary to use
the parking brake for this.
1.Hold the vehicle in place by pressing the
foot brake.2.Release the foot brake and drive off with‐
out delay.
The vehicle is held for approximately 2 sec‐
onds after the foot brake has been released.
Depending on the vehicle's load or when tow‐
ing a trailer, the vehicle may roll backwards a
little.
Servotronic
Principle The Servotronic varies the steering force re‐
quired when steering, depending on the
speed. At low speeds the steering force is
heavily supported, in other words a slight force
is needed when steering With increasing
speed the support for the steering force is re‐
duced.
In addition, steering force is adapted according
to drive program, giving a sporty/direct or com‐
fortable steering response.
Programs Adjustment possibilities of the steering force:▷"Comfort": low.▷"Sport": medium.▷"Sport Plus": high.

Park Assistant
Principle
The system supports you when parking in par‐
allel to the road.
Ultrasonic sensors measure parking spaces on
both sides of the vehicle.
The park assistant calculates the ideal parking
line and takes over steering during the process
of parking.
When parking up, also follow the visual and au‐
dible information and notes of the PDC, the
Park Assistant and the rear-view camera, and
respond accordingly.
The park assistant incorporates Park Distance
Control, PDC, see page 131.
Notes WARNING
The system does not take your personal
responsibility from you when you are estimat‐
ing the traffic situation. Due to limits of the sys‐
tem, it cannot respond independently in a rea‐
sonable way in all traffic conditions. Danger of
accidents. Adapt driving style to the driving
conditions. Observe the traffic situation and in‐
tervene actively if the situation warrants it.◀
