WARNING

Incorrect handling of airbag units

- Triggering of airbag unit
- System faults can occur

-> Switch off ignition and remove ignition key.
-> 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 the airbag unit in such a way that the airbag opening is facing upwards.
-> If removed for an extended period, the airbag unit 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.

Information

- 6 sensors are used for the airbags in the Panamera.

- The front two sensors are located on the lock support.

- The middle two sensors are located on the door sill behind the A-pillar.

- The rear two sensors are located on the rear wheel housings.
