| WARNING | Driver/passenger airbag modules and pyrotechnical seat belt tensioners must never be taken apart, repaired or transferred to another vehicle. |
| WARNING | Under no circumstances use an ohmmeter or other live measuring instrument to take readings on a disconnected non-deployed airbag or seat belt tensioner. This could deploy the modules / seat belt tensioners. |
Scheme 234
When temporarily storing the driver air bag module, it must be placed with the metal side (reverse) downwards in a well padded place to prevent damage to the surface material.
Note. For longer storage periods (unattended storage), airbag modules, inflatable curtain (IC) modules and other pyrotechnical components must be stored at a dedicated site in the original packaging.
Note. In the event of a fire at the storage site, the fire authorities must be informed about the presence of pyrotechnical components according to the relevant national statutory requirements.
Note. Loose Inflatable curtain (IC) modules must always be stored in Inflatable curtain (IC) racks, or in other approved packaging.
Note. Airbag modules must not be exposed to temperatures above 110°C.
Airbag modules and pyrotechnical components must be transported according the relevant national statutory requirements.

If dismantling the contact reel it is very important that the catch function on the connector is released first. Disconnection should be done in line with the attachment so as not to damage it.
Note. The use of tools of any kind are not advised when disconnecting due to an increased risk of damage to the connector.
Scheme 241
The contact is securely installed to make the contact attachment durable.
| WARNING | A damaged connector can cause failures in the function of the supplemental restraint system (SRS). |
