my X is set up different , one push locks and alarms , a second push after first push then disables interior and tilt sensor for leaving pets inside or transporting vehicle .
same sequence if using key in lock , turn once for full alarm then turn again to disable interior and tilt sensors .
the hood sensor makes sense because my 7 series alarm sometimes sounded in the wind when the car was in it`s pyjamas for the winter ( wrapped in a cover ) .
