Following an accident:
- The airbag and emergency tensioning retractor restraint system is to be checked for external damage and defects and as to whether it has been triggered
- Defective or damaged components must be immediately replaced. Repair of these components is not permitted
The restraint system control unit must be replaced:
- If the housing is deformed or otherwise damaged
- If the console is deformed; even if the restraint system control unit appears to be in good condition externally
- If there is an electrical defect
- Or after the airbag has deployed three times

A new restraint system control unit must be programmed and parameterized after installation.

The airbag or emergency tensioning retractor units must be replaced:
- Following deployment
- If there is external damage (even without deployment)
- Or if there is an electrical defect

After the driver airbag has been deployed, the steering wheel and steering column tubes with crash element must be replaced. If axial play or a noise is detected at the steering column tube, this must also be replaced, even if the airbag was not deployed.

In the following model designations, an exchange of the steering column tube can possibly be avoided if the above criteria have not been met:

Model 129
Model 163
Model 168
Model 170
Model 202
Model 203 without code (494) USA version
Model 203 without code (275) Driver seat, steering column and electrically adjustable outside mirrors with memory
MODEL 208
Model 209 without code (494) USA version
Model 209 without code (275) Driver seat, steering column and electrically adjustable outside mirrors with memory
Model 210 without code (275) Driver seat, steering column and electrically adjustable outside mirrors with memory
Model 169 without code (441) Manually adjustable steering column
Model 245 without code (441) Manually adjustable steering column

Proper function of the steering column tube is only guaranteed if the crash element is not damaged in any manner.

The dashboard must be replaced after the front passenger airbag has deployed.

The sidebag cover in the door lining and the side paneling must be replaced after the sidebag has been deployed.

Otherwise the airbag cannot be guaranteed to function correctly.
