Driving stability control
systems
gitudinal and lateral acceleration when driving
on dry surfaces, yet with reduced driving stabil-
ity. 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 neces-
sary.
Your BMW has a number of systems that help
to maintain the vehicle's stability even in
adverse driving conditions.
Antilock Brake System ABS
ABS prevents locking of the wheels during
braking. Safe steering response is maintained
even during full braking. Active safety is thus
increased.
M Dynamic Mode is switched off every time the
engine is restarted.
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.<
The ABS is operational every time you start the
engine. Braking safely, refer to page 117.
To maintain vehicle stability, drive with
the DSC activated and the
Electronic brake-force distribution
The system controls the brake pressure in the
rear wheels to ensure stable braking behavior.
M Dynamic Mode deactivated whenever possi-
ble.<
Brake assist
Activating MDM
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.
Press the
button on the steering wheel, refer
to MDrive* on page 50. The MDM indicator
lamp in the instrument cluster lights up if you
previously selected the M Dynamic Mode MDM
in MDrive.
When the ignition is on, you can set the
M Dynamic Mode via MDrive on the Control
Display.
Do not reduce the pressure on the brake for the
duration of the full braking application.
iDrive, for operating principle refer to page 16.

"Settings"
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.
"MDrive"
"DSC:"
Select "M Dynamic Mode".
The laws of physics cannot be repealed,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 lon-
