Installing

WARNING
Observe safety instructions for pyrotechnic components → Chapter.
Before handling pyrotechnic components (e.g. connecting the electrical connector), the person handling them must ensure that he/she is “electrically discharged”. To do this e.g. briefly touch the door striker plate.
  • Push connector -1- onto crash sensor until it engages audibly -arrow-.
  • Press in connector lock -2- to lock the connector.
Further installation is carried out in reverse order of removal. Observe the following: Note
Ensure that the electrical connectors are pushed fully onto stop and engage audibly.
Ensure that no wires are trapped.
WARNING Battery must be connected with ignition switched on. If pyrotechnic components (e.g. airbag, seat belt tensioners) are repaired incorrectly, undesired triggering may occur after the battery is connected. Ensure that nobody is in vehicle when connecting battery.
