First read and observe the introductory information
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 the belt tensioners could function incorrectly, or not function at all, in the event of an accident.
Regulations must be observed to ensure that the effectiveness of the belt tensioner is not reduced and that removed parts do not cause any injuries or environmental pollution. Qualified workshops are familiar with these requirements.

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