The term shift lock combines the functions which, in addition to the parking brake, offer an additional safeguard for the vehicle to prevent it moving off unintentionally. Included in this are the functions of locking the selector lever position "P" and locking the ignition switch as well as the park pawl in the transmission. The Shift-Lock only permits shifting out of selector lever position "P", if the transmitter key (A8/1) has been turned into position "circuit 15 ON" and the brake pedal is depressed. The vehicle is secured mechanically by blocking the parking lock gear. In order to ensure that after parking the vehicle the selector lever is shifted into selector lever position "P", it is only possible to turn the transmitter key (A8/1) towards "0" in this position and to remove it from the electronic ignition switch control unit (N73).

Simultaneously the function of locking selector lever position "P" serves as antitheft lockout. For this reason it is not possible to move the selector lever out of position P" in the event of failure of one of the following components:

• EIS [EZS] control unit (N73)
• Electronic selector lever module control unit (N15/5)
• Voltage supply
• Controller Area Network (data bus/CAN bus) (CAN)
• Stop lamp switch (S9/1)
• R/P locking solenoid
