Necessary preliminary tasks:
IMPORTANT: Secure vehicle against rolling, e.g. with chocks.
Using an 7 mm WAF hexagon socket wrench (1), turn back brake caliper spindle in clockwise direction.
Turn back until wheel can turn freely.

At the end stop a fault code is set which will cause the system to shut down! If this is the case, clear the fault memory
NOTE: Start-up after open circuit:
- Switch on ignition.
- Press brake button with brake pedal pressed.
- The indicator light in the instrument panel goes out as soon as the parking brake is released.
