24 34... Release transmission lock electronically: Notes

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

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

• Emergency release is only possible if the engine does not start and the starter turns over.
• If an emergency release needs to be performed although the engine starts, pull out the fuse of the electrical fuel pump.
• Emergency release is active for 15 min.
• As soon as a wheel speed signal is recorded, this time increases by 15 min.
• After this period, the parking lock is engaged without a message.
• The time specification 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 UNDERNEATH VEHICLE)  and MANUAL EMERGENCY RELEASE OF TRANSMISSION LOCK .
• The vehicle must be raised and the underbody panelling removed in order to operate the mechanical emergency transmission release. See MANUAL EMERGENCY RELEASE OF TRANSMISSION LOCK .
  IMPORTANT: To operate the electronic emergency transmission release the vehicle must not be towed but rather only pushed.
  In the case of misuse, a corresponding fault code is stored in the fault code memory.
