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.

•► To deactivate: press and hold button 1 for about five seconds until a tone sounds.
•► To activate: press and hold button 2 for about five seconds until a tone sounds.
i If you press one of the two buttons and do not hear a tone, the relevant setting has already been selected.
You can also switch the automatic locking function on and off using the on-board computer
