Engine Shutoff
If the key is turned to position "1" or "0" in the ignition while the selector lever is in the forwards or reverse position, a gear automatically remains engaged. If the key is turned to position "1" or "0" in the ignition while the selector lever is in idle-speed position "0", a gong sounds and the gear indicator flashes in the SMG display as a reminder that the car has not been secured against rolling away. The warning is silenced after approximately 10 seconds. If the selector lever is moved to the forwards or reverse position during this time, a gear is engaged automatically.
