Air bags
Introduction The installation point of an air bag can be rec-
ognized by the AIRBAG marking.
An air bag complements the correctly fastened
seat belt. It is no substitute for the seat belt. The
air bag provide sa dditional protection in appli-
cable accident situations.
Not all air bags are deployed in an accident. The
different air bag systems function independ-
ently from one another ( Y
page 50).
However, no system available today can com-
pletel ye liminate injuries and fatalities.
It is also not possible to rule out ar isk of injury
cause dbyana ir bag due to the high speed at
which the air bag must be deployed.
