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.
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.
