→ 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 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.
