and safety warnings
Seat belts may become damaged during any work on the belt tensioners or while removing or refitting any vehicle parts in conjunction with any other repair work. This damage will not always be noticeable. The consequence may be that, in the event of an accident, the belt tensioners function incorrectly or not at all.
So that the effectiveness of the belt tensioner is not reduced and that removed parts do not cause any injuries or environmental pollution, regulations must be observed. Qualified workshops are familiar with these requirements.

WARNING
The airbag modules and belt tensioners may contain perchlorate. Please comply with legislation regarding disposal.
