If the closing procedure of any of these elements is blocked, it will stop and open slightly. Once the hazardous situation no longer exists and an accident has been avoided, the PRESAFE® system loosens the seat belt pretension and decreases the air pressure in the air pockets of the multicontour and/or drivedynamic multicontour seats. All of the PRESAFE® system settings can be re-adjusted following the critical driving event.
