GENERAL INFORMATION
The
Supplemental Restraint System (SRS) and seat belt with pre-tensioner
is designed to supplement the driver’s and front passenger’s
seat belts to
help reduce the risk or severity of injury to the driver and front
passenger by activating and
deploying both front air bags in certain frontal collisions. The
side-air bag and the curtain
air bag are activated when an impact exceeds the threshold upon a side
collision, and inflates
to protect the heads of the occupants in the front and rear
seats.
The SRS consists of air bag modules, SRS air bag control unit
(SRS-ECU), two front impact sensors,
two side impact sensors, SRS warning lamp, clock spring and seat belt
pre-tensioner. Front air
bags are located in the centre of the steering wheel and above the glove
box. Each air bag is made
up of a folded air bag and an inflator unit. Side-airbags are located
inside the front seatback assemblies.
The curtain air bag module consists of an air bag, an inflator, and the
fixing gear relating
to those parts, and is installed in the roof side sections (from the
driver’s and the
passenger’s front pillars to the rear pillars).The SRS-ECU under
the front floor console
monitors the system and has a front air bag analogue G-sensor, front air
bag analogue G-sensor and
a side (curtain) air bag analogue G-sensor. The front impact sensor is
installed on the front
end upper bar in the engine room and contains an analogue G-sensor. The
side impact sensor is
installed in the lower parts of the centre pillars, and contains an
analogue G-sensor. The warning
lamp on the instrument panel indicates the operational status of the
SRS. The clock spring is
installed in the steering column. The seat belt pre-tensioner is built
into the driver’s
and passenger’s front seat belt retractor.
Only authorized
service personnel should do work on or around the SRS components. Those
service
personnel should read this manual carefully before starting any such
work.
