This can be done from inside the passenger compartment or underneath the vehicle.
Secure the vehicle against rolling away before releasing the parking lock.
In the event of an open circuit, e.g. flat battery or electrical fault, the parking lock must be released manually, otherwise the wheels will be locked and the vehicle cannot be moved.
Necessary preliminary tasks:
- Remove rear UNDERBODY PROTECTION .
Raise vehicle.
Manually operate the parking lock emergency release.
