The front and side Supplementary Restraint System (SRS) includes up to 6 airbags. They are located in:
The steering wheel hub and front passenger instrument panel (front airbags)
The outboard sides of the front seatbacks (side airbags)
The front and rear window pillars and the roof edge along both sides (curtain airbags).
These systems operate independently depending on the type of accident encountered. The front SRS airbags are activated by strong frontal collisions. Together with the restraining effort of the seat belts, they help reduce the risk of serious injury to the head and upper torso of the driver and front passenger.
In the event of a significant side-on impact, side and curtain airbags deploy to minimise the shock inflicted on the chest, head and neck areas of front and rear seat passengers.

During a frontal collision occupants continue moving with the force of the vehicles speed prior to the crash known as inertia this force can carry occupants into the steering wheel dashboard or windscreen causing serious injury the purpose of seatbelts and airbags is to safely stop the effects of this inertia and protect occupants from possible injury seatbelts are designed.

To prevent occupants from sudden forward movements and provide excellent general protection from injury they also ensure occupants are in the correct position for airbag deployment airbags are designed to deploy only during moderate to severe collisions and can operate in different combinations depending on the type and severity of collision the system usually comprises front side and.

Curtain airbags front airbags deploy in frontal or frontal offset impacts located in the steering wheel hub and passenger-side dashboard they are designed to minimize head neck and chest injuries side airbags protect occupants during side impacts and may also deploy during vehicle rollover located in the sides of front seats they are designed to inflate between occupants and doors.

System takes action within about 20 milliseconds it evaluates the speed and direction of the deceleration first the seatbelt pretensioners tightens the seatbelt across the occupants lap and chest to restrain the occupant from excessive forward movement and ideally position them for airbag deployment as the occupants inertia drives them forward.

A load limiter relaxes the seatbelts tension in a controlled manner to reduce the amount of pressure on the occupants chest if the impact force is sufficient airbags will also deploy at about the same time in a frontal impact a signal ignites a chemical reaction producing a rapid expansion of nitrogen gas inflating the airbag within about 30 milliseconds.
