But when I programmed my friends car to auto lock when driving off it was as simple as starting the car and then pressing and holding the lock button on the dash until you hear a beep.

I'm sure its in the manual somewhere


from the later manual (2006) wrote:Anti-theft protection
On starting the vehicle, the system automatically locks the doors as soon as you reach approximately 10 km/h.
Note: If a door has been opened, this will lock again automatically when the vehicle reaches approx. 10.

Activation/Deactivation of the function
After switching on the ignition, give a long press on the central unlocking button until a message is displayed.
