GENERAL INFORMATION
To improve safety, the SRS and seat belts with
pre-tensioner are available as optional parts. These
systems enhance collision safety by restraining the
front passengers in case of an accident. The SRS
works with the pre-tensioner simultaneously when
a collision is detected.
The SRS consists of four air bag modules, SRS
air bag control unit (SRS-ECU), front impact
sensors, side impact sensors, SRS warning lamp
and clock spring. The air bags are located in the
centre of the steering wheel, above the glove box,
and built into the front seat back assemblies. Each
air bag has a folded air bag and an inflator unit.
The SRS-ECU under the floor console monitors
the system and has a safing G sensor and an analog
G sensor. The front impact sensors are installed
on the front side member. The side impact sensor
inside the quarter panels, inner monitors any shocks
coming from the side of the vehicle. The warning lamp on the instrument panel indicates the
operational status of the SRS. The clock spring
is installed in the steering column.
The SRS side air bag deploys if an impact received
at the side of the vehicle is stronger than a certain
set value, in order to protect the upper bodies of
front seat passengers in the event of a collision.
The seat belt pre-tensioner is built into the front
seat belt retractor. Only authorized service
personnel should do work on or around the SRS
components and seat belt with pre-tensioner. Those
service personnel should read this manual carefully
before starting any such work. Extreme care must
be used when servicing the SRS to avoid injury
to the service personnel (by inadvertent deployment
of the air bags or inadvertent operation of the seat
belt with pre-tensioner) or the driver (by rendering
the SRS or the seat belt with pre-tensioner
inoperative).
