Operation after interruptions in 
power supply 
The parking brake may only be used 
again, if it was released manually after 
an interruption in power supply, i.e. as a 
result of a discharged or disconnected bat-
tery. If this is not done, the parking brake 
may fail to operate correctly. Even with the 
parking brake engaged, there would be a 
danger of the vehicle rolling on steep 
hills.

restored you can again use the parking 
brake: 
With the ignition on and the 
vehicle stationary, press the 
button briefly three times at 
intervals of approx. 5 seconds.

operation. The indicator lamp
in 
the Info Display goes out.
