C5 X7 2010 - seatbelt display above rear mirror

I'm not really sure what this is supposed to show. Mine never lights up. Also, there is no audible warning if the front passenger (this is a LHD car) does not connect seatbelt. Driver seatbelt not connected does make the warning sound.

I have no sound but the symbol shows if the passenger does not fit their belt. The same in the rear .
Symbol flashing and sound if the driver does not.
All lights go through a test session on key turn.

You'll get an alarm sound if the passenger seat belt is released or you press the seat belt clip button.

sounds like someone has had a Lexia session?

did this to mine when it was the work hack, i turned off as many alarms as possible for when i carried things on the front seat and rears

Thanks. So is there a simple way to restore the ''lighting up on turning the key''?
