If the brake warning lamp comes on
together with the yellow indicator
lamps for the Antilock Brake Sys-
tem ABS and the Dynamic Stability
Control DSC:
The entire ABS and DSC control
system has failed. Continue driving
cautiously and defensively. Avoid

hard brake applications. Please have the
system checked by your BMW center as
soon as possible.

Dynamic Stability Control DSC for
Canadian models.

Switching off DSC/Activating DTC

Press the DSC button briefly. The DTC indi-
cator lamp comes on and stays on.

DSC has been switched off; DTC is in ready
mode.
In the following exceptional circumstances,
it may be effective to activate the DTC for a
short period:

When rocking the vehicle or starting off
in deep snow or on loose surfaces

When driving on snow-covered grades,
in deep snow, or on a snow-covered
surface that has been packed down
from being driven on

When driving with snow chains.

The gain in traction is achieved by a reduc-
tion in stabilizing intervention.

Switching off DSC and DTC

Hold the DSC switch down for at least
3 seconds. The DSC indicator lamp stays
lit.

In this case, no interventions to increase
stability and traction for the engine and
brakes are carried out.

To maintain vehicle stability, drive
with the DSC switched on whenever

possible.

Reactivating DSC and DTC

Press the button again.
The indicator lamp goes out.

The laws of physics cannot be
repealed with DSC. It will always be

the driver's responsibility to drive in a man-
ner that matches road conditions. We
therefore urge you to avoid using the addi-
tional safety margin of the system as an
excuse for taking risks. Stabilizing interven-
tion is only performed to a limited degree
when the DTC is activated.
Do not make any modifications to the DSC
system. Allow only authorized technicians
to perform service procedures on the
DSC.

Dynamic Brake Control DBC

If you step on the brake rapidly, this system
automatically produces maximum braking
force boost and thus helps to achieve the
shortest possible braking distance during
panic stops. All of the benefits of the ABS
system are exploited under these circum-
stances.

Do not reduce the pressure on the brake
pedal for the duration of the brake applica-
tion. When the brake pedal is released, the
DBC is deactivated.

Brake force display

The Brake force display indicates to the
road user behind you how hard you are
braking.
