Dynamic Stability Control (DSC) 
Hill Descent Control
To deactivate the system 
Press the button (arrow); the indicator 
lamp comes on and stays on. 
Traction intervention remains active; 
that is, braking intervention will 
continue. Refer also to "Four-wheel 
drive" on page 
In the following exceptional circum-
stances, it may be effective to deacti-
vate the DSC for a short period: 
>
When rocking the vehicle or starting 
off in deep snow or on loose 
surfaces. 
>
On sandy road surfaces. 
>
On poor surfaces with deep ruts. 
>
If the wheels "churn" on muddy 
surfaces. 
>
When driving with snow chains.

As a result of the traction interven-
tion, the brakes may be subjected 
to additional loads when the system is 
deactivated. For this reason, it is 
possible that the braking intervention 
will be disabled automatically for a brief 
period in order to limit brake tempera-
ture.
To maintain vehicle stability, always 
drive with the system switched on when 
possible.

To reactivate the system
Press the button again; the indicator 
lamp goes out. 
The laws of physics cannot be 
repealed, even with DSC. An 
appropriate driving style always 
remains the responsibility of the driver. 
We therefore urge you to avoid using 
the additional safety margin of the 
system as an excuse for taking risks.
Do not make any modifications to the 
DSC system. Service procedures on 
the system are to be performed by 
authorized technicians only.

For additional details concerning DSC, 
please refer to the chapter describing 
"Advanced technology" on page 
The concept 
HDC is a system for driving downhill in 
steep terrain. This system reduces 
vehicle speed on steep downhill gradi-
ents, thus allowing you to maintain 
control of your BMW under these 
conditions.
The vehicle moves at slightly more than 
walking speed without active interven-
tion from the driver. 
You can activate HDC below approx. 
20 mph (30 km/h). When driving down 
steep hills, the vehicle reduces speed 
automatically down to slightly more 
than walking speed (approx. 5 mph/
8 km/h) and then maintains this speed 
at a constant. 
By applications of the brakes or accel-
erator, you can alter this speed in the 
range of approx. 3 mph (5 km/h) to 
approx. 20 mph (30 km/h).
HDC is deactivated automatically if you 
exceed approx. 35 mph (60 km/h).
