SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
M1001009800020
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 consist of four 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. Side air bag are
located inside the front seatback assemblies. Each
air bag is made up of a folded air bag and an inflator
unit. The SRS-ECU under the front floor console
monitors the system and has a front air bag safing
G-sensor, front air bag analog G-sensor and a side
air bag safing G-sensor. The front impact sensor is
assembled outside the headlamp support panel to
monitor impact in case of front impact. The side
impact sensors inside the centre pillars monitor the
shock incurred by the sides of the vehicle. 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.
