Before beginning with

body repairs
work on airbag or ETR 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 lead from battery.

Before commencing welding work

Remove ignition key and disconnect/insulate ground line from battery
Disconnect coupling from airbag control unit with ETR unit

For painting

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.

During repair work

Do not bring airbag and emergency tensioning retractor units into contact with grease, oil or cleaning agents
Airbag or ETR 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

Following work on airbag and ETR units,

the supplemental restraint system (SRS) must always be checked using STAR DIAGNOSIS.
