Have a malfunction corrected only by a
BMW center or a repair shop that works in
accordance with BMW guidelines and uses
appropriately trained personnel. Only techni-
cians can return the parking brake to normal
operational status after it has been released
manually in response to a malfunction.
<
Following manual release, the actual sta-
tus of the parking brake may deviate from
that displayed by the indicator lamp. <
Operation after interruptions in power
supply
The parking brake can only be used again
if it was manually released due to an inter-
ruption in the supply of electrical power. Other-
wise, the function of the parking brake is not
guaranteed and there is a danger of the vehicle
rolling despite the parking brake being
engaged.
<
Once the electrical power supply has been
restored, you can again use the parking brake:
With the ignition on and the vehicle
stationary, briefly press the button
three times at intervals of approx.
5 seconds. This executes the fol-
lowing initialization sequence:
> Initializing the disengaged setting.
> Engaging: the system registers the new
status and the brake setting is initialized.
