- Fig. 1 Selector lever lock functions
Applies to Audi A4s: with multitronic/S tronic/tiptronic
The selector lever lock prevents gears from being engaged inadvertently, so that the Audi A4 is not set in motion unintentionally.
The selector lever lock is released as follows:
Switch on the ignition.
Press the brake pedal and at the same time press in the interlock button.
Automatic selector lever lock
The selector lever is locked in the P and N positions when the ignition is on. The driver must apply the footbrake and simultaneously press in the interlock button before the lever can be moved out of either of these positions. The following message appears in the instrument display as a reminder for the driver when the selector lever is in position P or N:
When stationary apply footbrake while selecting gear
The selector lever lock only works if the Audi A4 is stationary or driving at speeds up to 2 km/h. At higher speeds the selector lever lock in the N position is disengaged automatically.
The selector lever lock is not engaged if the selector lever is moved quickly through position N (e.g. when shifting from R to D/S). This makes it possible, for instance, to "rock" the Audi A4 backwards and forwards if it is stuck in snow or mud. The selector lever lock engages automatically if the brake pedal is not depressed and the lever is in position N for more than 2 seconds.
Interlock button
The interlock button on the selector lever handle prevents the driver from inadvertently engaging particular gears. The illustration shows the selector lever positions in which the button has to be pressed, highlighted in colour Fig. 1.
Safety interlock for ignition key
The key can only be withdrawn with the ignition switched off and the selector lever in position P. When the ignition key is removed, the selector lever is locked in position P.
