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 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. 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. Side air
bags are located inside the front seatback assemblies. The SRS-ECU under
the front floor console monitors the system and has a front air bag
safing G-sensor, front air bag analogue 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.
