Before beginning with
- bodywork
- work on airbag or RTE units (removal, installation)
- work on components that are associated with the airbag and emergency tensioning retractor units or require access to their electric circuit, e.g. when removing the steering wheel, disconnect/insulate ground line from battery.
Before beginning with welding work
- Remove ignition key and disconnect/insulate ground line from battery
- Disconnect coupling from airbag control unit with RTE unit
For painting work
involving force drying, there are no special safety regulations to observe.
The airbag and emergency tensioning retractor units can withstand temperatures of up to 100 °C without sustaining any damage.
For repair work
- Do not bring airbag and emergency tensioning retractor units into contact with grease, oil or cleaning agents
- Airbag or RTE units which have fallen from a height of more than 0.5 m must be replaced and must not be installed in a vehicle under any circumstances
- In order to be able to install emergency tensioning retractor units free from damage and dirt, they have been provided with a PVC film protective sleeve. This protective device must be removed after assembly. To prevent the belt from being damaged in the process, do not use any sharp-edged tools
After finishing the work on the airbag and emergency tensioning retractor units,
the supplemental restraint system should always be checked using Star Diagnosis.
