PDC Park Distance Control*
The concept
The PDC assists you when you are parking.
Acoustic signals and an optical display
* alert
you to the approach of an object from behind
your vehicle. To measure the distance, there
are four ultrasonic sensors in each bumper.
The range of these sensors is approx. 7 ft/2 m.
However, an acoustic warning first sounds for
the sensors at the front and at the two rear cor-
ners at approx. 24 in/60 cm, and for the center
rear sensors at approx. 5 ft/1.50 m.
PDC is a parking aid that can indicate the
presence of objects when they are being
approached slowly, as is usually the case when
parking. Avoid approaching an object at high
speed; otherwise, the physical circumstances
could cause the system warning to be activated
too late.<
Switching on automatically
The system starts to operate approx. 1 second
after you shift into reverse gear or move the
selector lever into position R with the engine
running or the ignition switched on.
Wait this short period before driving.
Switching on manually
Press the button; the LED lights up.
Switching off manually
Press the button again; the LED goes out.
After driving approx. 165 ft/50 m or at over
approx. 20 mph/30 km/h, the system is
switched off and the LED goes out. You can
reactivate the system manually as needed.
Signal tones
An intermittent signal indicates the distance of
the vehicle from an object being approached.
Thus, an object detected to the left rear of the
vehicle will be indicated by a signal tone from
the left rear speaker, etc. As the distance
between vehicle and object decreases, the
intervals between the tones become shorter. If
the distance to the nearest object falls to below
roughly 1 ft/30 cm, then a continuous tone
sounds.
An intermittent tone is interrupted after approx.
3seconds:
>if you remain in front of an object that was
only detected by one of the corner sensors
>if you drive parallel to a wall
Malfunction
The LED in the button flashes and a message
appears on the Control Display. PDC is mal-
functioning. Have the system checked.
As a preventive measure, keep the sensors
clean and free of ice or snow in order to ensure
that they will continue to operate effectively. Do
not spray the sensors with high-pressure clean-
ers for long periods and maintain a distance of
at least 4 in/10 cm to them.
Exhaust gases near the rear sensors can cause
a signal tone to sound.

Brake assistant
When you apply the brakes rapidly, this system
automatically produces the maximum braking
force boost and thus helps to achieve the short-
est possible braking distance during full brak-
ing. This system exploits all of the benefits pro-
vided by ABS.
Do not reduce the pressure on the brake pedal
for the duration of the full braking.
DSC Dynamic Stability Control
DSC optimizes the vehicle stability and traction.
It also detects unstable driving states such as
understeering and oversteering, and helps
keep the vehicle on course within the physical
limits by reducing the engine output and by
braking at the wheels.
The DSC is operational every time you start the
engine.
The laws of physics cannot be repealed,
even with DSC. An appropriate driving
style always remains the responsibility of the
driver. Do not reduce the additional safety mar-
gin of the system by taking risks.<
Indicator lamp
The indicator lamp goes out shortly
after the engine is started.
The indicator lamp flashes: DSC is con-
trolling the drive forces and brake forces.
The indicator lamp lights up continuously: DSC
is deactivated.
M Dynamic Mode MDM
The M Dynamic Mode is a mode of the DSC
Dynamic Stability Control. It enables driving
with greater longitudinal and lateral accelera-
tion on dry road surfaces, however with limited
vehicle stability. The system does not provide
stabilizing intervention by reducing the engine
output and braking at the wheels until the abso-
lute driving limit is reached. Steering correc-
tions by the driver may also be required in this
driving state.
The M Dynamic Mode is deactivated each time
the engine is started.With the M Dynamic Mode activated, sta-
bilizing interventions are only carried out
to a reduced degree.<
To maintain vehicle stability, drive with
DSC activated and the M Dynamic Mode
deactivated whenever possible.<
Indicator lamp
The indicator lamp goes out shortly
after the engine is started. The indica-
tor lamp lights up continuously:
M Dynamic Mode is activated.
The indicator lamp lights up continuously and
the DSC indicator lamp flashes: the M Dynamic
Mode is active and controls the drive and brak-
ing forces.
Activating MDM
You activate the M Dynamic Mode with the
button on the steering wheel, refer to MDrive on
page54.
With the ignition switched on you can change
the settings of MDrive on the Control Display.
iDrive, for explanation of principle, refer to
page16.

EDC Electronic Damping
Control
The concept
If the influencing variables such as road surface
quality or operating conditions such as steer-
ing, braking etc. change, the damping automat-
ically adjusts to the new conditions within a
fraction of a second.
You can choose from three programs.
"Comfort" program
Select the "Comfort" program if you want com-
fort-oriented coordination of shock absorbers
and steering.
"Normal" program
The "Normal" program offers a balanced mix-
ture of the comfort and the sport program.

FTM Flat Tire Monitor*
The concept
The Flat Tire Monitor keeps track of the infla-
tion pressures in the tires as you drive. The sys-
tem provides an alert whenever the inflation
pressure drops significantly in relation to the
pressure in another tire.
In the event of a pressure loss, the rolling radius
and therefore the rotation speed of the wheels

change. This change is detected and signaled
as a flat tire.
Functional requirement
To ensure the reliable signaling of a flat tire, the
system must be initialized at the correct tire
inflation pressure.
The initialization must be repeated after
every correction of the tire inflation pres-
sure and after every tire or wheel change.<
System limits
The Flat Tire Monitor cannot indicate
sudden severe tire damage caused by
outside factors and does not detect a natural,
even pressure drop in all four tires.<
In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snow-covered or slippery roads
>Sporty driving style: slip in the drive wheels,
high lateral acceleration
>Driving with snow chains
*
Initializing system
The initialization finishes during driving,
which can be interrupted at any time.
When driving resumes, the initialization is auto-
matically continued.
Do not initialize the system when driving with
snow chains

Indication of a flat tire
The warning lamp lights up in red. A
message appears on the Control Dis-
play. In addition, an acoustic signal
sounds. There is a flat tire or extensive inflation
pressure loss.
1.Reduce speed and stop the vehicle care-
fully. Avoid sudden braking and steering
maneuvers.
2.Identify damaged tire. To do this, check the
tire inflation pressure using the M Mobility
System, refer to Producing tire inflation
pressure on page214.
3.Repair flat tire with M Mobility System, refer
to page212, or replace the damaged wheel,
refer to Changing wheels on page215.
TPM Tire Pressure Monitor*
The concept
TPM checks the tire inflation pressure in the
four mounted tires. The system reports when
the tire inflation pressure has dropped consid-
erably in one or several tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must have been reset with the
correct tire inflation pressure.
Always use wheels with TPM electronics, oth-
erwise fault-free operation of the system is not
ensured.
Reset the system again after each correc-
tion of the tire inflation pressure and after
every tire or wheel change.<
System limits
TPM cannot announce sudden serious
tire damage caused by external influ-
ences.<
The system does not function properly if it has
not been reset, e.g. a flat tire is reported despite
correct tire inflation pressures.
The system is inactive and cannot display a flat
tire if a wheel has been mounted without TPM
electronics, or if TPM is temporarily interfered
with by other systems or devices which use the
same radio frequency.
Status display on Control Display
The tire and system status is indicated by the
color of the tires.
TPM takes the fact that the tire pressure
changes during driving into account. A correc-
tion is only required if requested by TPM with
the color.
Green
The tire pressure matches the learned set state.
"TPM active" is displayed on the Control Dis-
play.
One wheel is yellow
Flat tire or a major drop in inflation pressure in
the indicated tire. A message appears on the
Control Display.
