Seat-Belt Pretensioners
- Triggering of airbag unit.
- System faults can occur.
→ Switch off ignition and remove ignition key or remote control (hand-held transmitter).
→ A voltage supply (e.g. battery charger) must not be connected to the external power supply/jump-lead starting terminals.
→ Disconnect the battery and insulate the ground strap so that all contact with a ground carrier is avoided.
→ Wait 1 minute after disconnecting the battery.
→ Only pull off connector on the triggering unit after the waiting time has elapsed.
→ Make sure that no foreign objects are located in front of the airbag unit during installation.
→ Replace damaged parts during removal.
→ Always position airbag units so that the blow-out opening is facing upwards, e.g. crest on driver's airbag.
→ Do not position anything on the airbag units.
→ If removed for an extended period, the airbag units must be stored in a safe place.
→ Airbag units must not come into contact with grease, oil, detergents, liquids, or similar substances.
→ Do not expose airbag units to temperatures of more than 90°C.
→ Do not remove the short-circuit spring on the plug-in contacts.
→ Ignition and preparations may only be carried out by skilled staff, supervised by a second responsible person.
→ Before disposal, the airbag unit must be rendered harmless by electrical ignition performed in accordance with all precautionary measures, thereby preventing it from being used incorrectly.
Information
Only ignite airbag units that are securely installed in the vehicle and in the original condition. Use only the ignition tool intended for this purpose.
Carry out ignition only in suitable, open areas.
Only use an ignition tool intended for this purpose.
First remove all loose objects from the expansion area of the airbag.

Wear ear protectors. Keep a safe distance by utilizing the entire cable length of the ignition tool.
Connect power source only just prior to igniting.
If ignition fails, wait for approx. 3 minutes before approaching the airbag unit.
