Selector Mechanism And Ignition Key Withdrawal Lock, Checking
Proceed as follows:
- If selector lever is in S, D, R or Tiptronic position, starter cannot be operated.
- If vehicle is rolling faster than 5 km/h and selector lever is shifted to N, the selector lever lock solenoid must not engage and block selector lever. Selector lever can be shifted into driving gear.
- If vehicle is rolling at speeds less than 5 km/h (almost still) and selector lever is shifted to N, the selector lever lock solenoid may only engage after a second. The selector lever can only be shifted out of N when brake pedal is pressed.
Selector lever in P position, ignition switched off:
The ignition key can be removed.
Selector lever out of P position, ignition switched off:
The ignition key cannot be removed.
Selector lever in position P, button on selector lever pressed and ignition switched on:
- Brake pedal not pressed:
With button pressed, selector lever is locked and cannot be shifted out of position P. Shift lock solenoid blocks selector lever.
- Brake pedal pressed:
The selector lever lock solenoid releases selector lever, a driving gear can be engaged. Shift selector lever slowly through from P through R, N, D, S; while doing this check whether selector lever position in instrument cluster matches the selector lever position.
Selector lever in position n, button on selector lever pressed and ignition switched on:
- Brake pedal not pressed:
Selector lever is locked and cannot be shifted out of N position. Shift lock solenoid blocks selector lever.
- Brake pedal pressed:
The selector lever lock solenoid releases selector lever, a driving gear can be engaged.
- If the brake pedal is pressed, it is possible to shift from N to D without pressing button on selector lever.
