For various tasks, it is necessary to unlock and lock the parking lock.

Before releasing the parking lock, secure the vehicle against rolling away.

• The emergency release is only possible if the engine does not  start and the starter is turning.
• If the emergency release must be activated although the engine starts, the fuse for the electrical fuel pump may be pulled.
• The emergency release is active for 15 minutes.
• As soon as a wheel speed signal is recorded, this period will be extended by another 15 minutes.
• After this period of time, the parking lock will be engaged without message.
• The chronological information depends on the battery capacity.
• Only specially trained service personnel are permitted to operate both the mechanical as well as the electrical emergency transmission release system. See MANUALLY RELEASING PARKING LOCK (FROM VEHICLE UNDERBODY)  or MANUAL EMERGENCY RELEASE OF TRANSMISSION LOCK .
