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, passenger’s air bag cut off switch, passenger’s air
bag cut off indicator lamp 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 passenger’s air bag cut off
switch has been equipped in the instrument panel of passenger’s
side. The passenger’s air bag cut off indicator lamp is located
above the centre upper panel. 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.
