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.
