Crash sensor.

First aid: the crash sensor immediately recognizes when an accident has occurred and helps the vehicle's occupants to get out of the cabin as swiftly as possible by unlocking all doors.

Should an accident occur, the crash sensor overrides the central locking system, unlocking all the doors. This allows the driver and occupants to leave speedily - or assistance from outside to get into the cabin faster.
At the same time, the crash sensor also switches on the cabin lights and activates the hazard warning lights to alert other drivers of the situation.
