Driving stability control 
systems
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.
The ABS is operational every time you start the 
engine. Braking safely, refer to page
Electronic brake-force distribution 
EBV
The system controls the brake pressure in the 
rear wheels to ensure stable braking behavior.
Dynamic Brake Control DBC
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 for the 
duration of the full braking application.
Dynamic Stability Control DSC
DSC prevents the driving wheels from losing 
traction when you pull away from rest or accel-
erate. The system also recognizes unstable 
driving conditions, for example if the rear of the 
car is about to swerve or if momentum is acting 
at an angle past the front wheels. In these 
cases, DSC helps the vehicle maintain a safe 
course within physical limits by reducing engine 
output and through braking actions at the indi-
vidual 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The laws of physics cannot be repealed, 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.

Deactivating DSC
Press the button for at least 3 seconds; the indi-
cator lamps for DSC in the instrument cluster 
light up. Dynamic Traction Control DTC and 
DSC have been simultaneously deactivated. 
Stabilizing and drive-output promoting actions 
are no longer executed.
In the same way as with a differential interlock
*
even if DSC is deactivated, brake actions are 
still performed on the rear axle to enhance drive 
output if the drive wheels experience a signifi-
cant loss of traction.
To increase vehicle stability, activate DSC again 
as soon as possible.
Activating DSC
Press the button again; the indicator lamps for 
DSC in the instrument cluster go out.
For better control
If the indicator lamp flashes: 
DSC is regulating the drive and braking 
forces.
If the indicator lamps are on: 
DSC is deactivated.
Dynamic Traction Control DTC
DTC is a version of DSC in which the drive out-
put is optimized for particular road conditions, 
e.g. unplowed snow-covered roads. The sys-
tem assures the maximal drive output, but with 
reduced driving stability. It is therefore neces-
sary to drive with appropriate caution.
You may find it useful to briefly activate DTC 
under the following special circumstances:
