have been changed. <Vehicles
for Singapore>
The other service procedures are the same as

- Adoption of the side-airbag
- Addition of the side impact sensor
- Adoption of the passenger’s side lap
pre-tensioner
- Adoption of the front seat belt anchor adjuster
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-airbag 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), 1 front impact
sensor, 2 side impact sensors, SRS warning lamp, clock spring, lap
pre-tensioner 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 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.
