Safety battery terminal

Depending on the severity of the accident, the safety battery terminal may disconnect the starter motor, the alternator and the remote battery terminal from the battery. This prevents the risk of electrical short-circuits in a serious accident.

Even if the safety battery terminal is disconnected, the system ensures that voltage continues to be supplied to all safety-relevant electrical equipment, such as the hazard warning flashers, interior lamps and phone.
