4 Front airbag sensors
The front seat belt pretensioner system mainly consists
of the above components, and their locations are shown
in the illustration.
The front seat belt pretensioners are controlled by the
airbag sensor assembly. The airbag sensor assembly
consists of a safing sensor and airbag sensor.
When the front seat belt pretensioners are activated, an
operating noise may be heard and a small amount of
smoke–like gas may be released. This gas is harmless
and does not indicate that a fire is occurring.
Once the front seat belt pretensioners have been
activated, the seat belt retractors remain locked.
