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 the automatic locking function on and off using the on-board computer.
