SUPPLEMENTAL RESTRAINT
SYSTEM (SRS)
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 SRS and seat belt pre-tensioner
systems consist of air bag modules, SRS-ECU, two front impact
sensors, four side impact sensors, SRS warning lamp, clock spring, seat
slide sensor and seat
belt pre-tensioner. Airbag modules are installed at the centre of the
steering wheel, on the
globe box, in the front seatback and the roof-side area (from the front
pillars of driver- and
passenger-side to the rear pillar in rear area of vehicle). Each air bag
has a safing folded
air bag and an inflator. SRS-ECU, installed at the depths of the centre
console, monitors the
system. The front impact sensor is assembled in the radiator support
panel to monitor collision
upon frontal impact. The side impact sensor is assembled in the centre
pillar <All
model>
and quarter panel lower <Except vehicles for Hong Kong and
Singapore>
to
monitor collision upon side impact. 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 slide sensor
is attached to the seat rail and provides the air bag control unit with
information on the seat
position <Vehicles for Australia and New Zealand>. The seat
belt pre-tensioner
is incorporated in the 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.
