Automatic locking feature

The vehicle locks automatically when the ignition is switched on and the wheels of the vehicle are turning at a speed of more than 9 mph (15 km/h).

You could therefore be locked out when:
• the vehicle is being pushed.
• the vehicle is being towed.
• the vehicle is being tested on a dynamometer.

You can switch off the automatic locking function via COMAND.
