Vehicle equipment

In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. For this reason, descrip-
tions will be given of some equipment that may
not be available in a vehicle, for example due to
the special options or national-market version
selected. This also applies to safety related
functions and systems.

Driving stability control

systems

Contrary to the description in the Owner's Man-
ual for Vehicle, your BMW 1-Series M Coupe is
not equipped with Dynamic Traction Control
DTC.

Dynamic Stability Control DSC

DSC optimizes driving stability and traction. In
addition, the system recognizes unstable driv-
ing situations such as understeering and over-
steering, and helps keep the vehicle on a safe
course within physical limits by reducing engine
power and applying the brakes on individual
wheels.

The laws of physics cannot be repealed,
even with DSC. An appropriate driving

style always remains the responsibility of the
driver. Therefore, do not reduce the additional
safety margin again by taking risks, as this could
result in an accident.

M Dynamic Mode MDM

M Dynamic Mode is a mode of the Dynamic
Stability Control DSC that permits greater
longitudinal and lateral acceleration when
driving on dry surfaces, yet with reduced driving
stability. Only at the absolute limit of stability
does the system intervene to stabilize the

vehicle by reducing engine power and applying
the brakes on the wheels. In such situations,
additional corrective steering maneuvers may
be necessary.
M Dynamic Mode is switched off every time the
engine is started.

When the M Dynamic Mode is on, stabi-
lizing measures are performed to a limited

degree only. Take action yourself, otherwise
there is a risk of an accident.

To maintain vehicle stability, drive with
the DSC activated and the

M Dynamic Mode deactivated whenever possi-
ble.

Activating MDM

Push the button: the indicator lamps for MDM
and DSC OFF light up.

For better control

The indicator lamps MDM and
DSC OFF light up and the indicator
lamp DSC flashes:
M Dynamic Mode is controlling the
drive and braking forces.
The indicator lamp DSC lights up: DSC
and M Dynamic Mode have failed.
