General Description
GENERAL DESCRIPTIONWARNING: Extreme care must be used when servicing the SRS to avoid injury to the service personnel (by inadvertent deployment of the air bags) or the driver (by rendering the SRS inoperative).
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), SRS warning light, and clock spring. Air bags are located in the center of the steering wheel and above the glove box. Each air bag is made up of a folded air bag and an inflator unit. The control unit under the floor console monitors the system and has a safing G-sensor and an analog G-sensor. The warning light 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 information carefully before starting any such work.
GENERAL DESCRIPTION
CAUTION:
- Driver and front passenger air bags and seat belt pre-tensioner deploy and operate in all head-on collisions that exceed the threshold to activate the SRS system.
- The specific value is the equivalent impact when a vehicle collides against a concrete (fixed) wall at approximately 25 kph (16 mph) or more.
- The SRS and pre-tensioner may not work under the following conditions:
- A head-on collision is less than the specific value.
- A vehicle collides on its rear end.
- A vehicle rolls over or is in a similar position.
Apart from driver's and front passenger's air bags and seat belts with pre-tensioner fitted as standard, some models can be equipped with optional side air bags on both driver's and front passenger's sides, increasing the passive safety level.
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The SRS is designed to supplement the front seat belts. It eliminates or reduces or injury to the front passenger(s) by deploying air bag(s) in case of a head-on collision.
SRS SIDE AIR BAG
Side air bag systems in the front seats are activated when sideward impacts applied to the vehicle exceed a threshold to protect the occupants' upper bodies.
SEAT BELT WITH PRE-TENSIONER
The seat belts with pre-tensioner work simultaneously with the SRS. The pre-tensioner takes up seat slack immediately when a collision takes place by that restraining the front passengers sooner than the SRS. This prevents the passengers from moving forwards.
