Just go into the settings via the steering wheel buttons, it is in the convenience section, and my sound is the horn, so I switch it off!!! The wing mirrors folding in tell me its locked.......and if I only open the boot the system rearms itself, .....equally if I unlock but don't open the doors it rearms itself with the flashing indicators 3 times for locking and once for open.....
Then I found the instructions in the owners manual.
