Safety instructions, passenger's airbag unit
WARNING
Incorrect triggering of airbag module.
- Danger of injury and damage to property as a result of incorrect handling of airbag units!
-> The safety regulations => Safety regulations for handling airbag and belt tensioner units must be followed.
-> The airbag unit must always be stowed so that the airbag opening faces upwards!
-> If removed for an extended period, the airbag unit must be kept in a locked place!
-> Remove ignition key. Disconnect battery. Route or isolate ground strap so that all contact with a ground carrier (e.g. body, seat frame) is avoided.
-> After the battery is disconnected, always wait for 1 minute before disconnecting the airbag plugs.
CAUTION
Loosen the safety-related screw connection!
- Danger of injury and material damage if the airbag module is screwed on incorrectly!
-> Always replace fastening screws for the airbag unit after customer service and reworking.
-> It is not permissible to make alterations to the microencapsulated screws (e.g., use lubricant, loosen bolts, and screw them down again).

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.
