SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The front air bag 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 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 Supplemental Restraint
System (SRS) consists of air bag modules, SRS control unit (SRS-ECU),
front impact sensors, side impact sensor, SRS warning lamp, clock spring
and seat belt with pre-tensioner. Front air bags are located in the
centre of the steering wheel and above the glove box. Side-airbags are
located inside the front seatback assemblies. The curtain air bag module
is installed in the roof side sections (from the driver’s and the
passenger’s front pillars to the rear pillars). The knee air bag
module is installed under the steering column. Each air bag is made up
of a folded air bag and an inflator unit. The SRS-ECU is mounted on the
front of the floor console and has a front air bag safing G-sensor,
front air bag analogue G-sensor. The front impact sensor is installed
out side of the radiator support reinforcement. The side impact sensor
is installed in the lower parts of the centre pillars. The SRS warning
lamp on the instrument panel indicates the operational status of the
SRS. The clock spring is installed in the steering column. The lap
pre-tensioner has been installed on the outer seat belt lower anchor
side. 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.
