Mechanical tensioner: to avoid unnecessary activation, before working on the front seats and before removing them, be sure to insert the plastic safety fork attached to the belt tensioner housing. To gain access to the tensioner, unfasten the outer lining of the seat rail.
Pyrotechnic tensioner: To avoid unnecessary activation, always disconnect the battery before working on the front seats or before removing them. Insulate the negative terminal of the battery to avoid accidental electrical contact. After disconnecting the battery, wait at least two minutes for the capacitor to discharge. This prevents unauthorized activation of the seat belt tensioners and the airbag unit.
Safety instructions: Installation work on the front seat belts or their tensioners must only be carried out at a service station. Before disposing of a non-deployed seat belt tensioner, it must be triggered (at a service station).
