WARNING
Incorrect handling of airbag units
- 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 detach 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 above 90°.
-> 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.
Incorrect triggering of airbag modules.

Installing triggering unit
Information
If a new component (e.g. sensor, airbag control unit, airbag unit) of the airbag system has to be installed, the new component will be supplied with a barcode sticker (tear-off label).
Sample tear-off label shown >> airbag sensor
- Tear off the tear-off label -2- on the new component -1- and stick it under the heading Proof of airbag system check/component replacement in the Guarantee and Maintenance booklet.
Tear-off label
- The replacement date and mileage must be documented and the booklet must be stamped with the dealer's stamp.
1. Position the triggering unit, slide the three ground straps -2- onto the left fastening bolts and secure them with the three fastening nuts -1-. => Tightening torque: 8 Nm (6 ftlb.)
