How the SRS Air Bags Work
◆ Front Seat Belt Pretensioners
The front seat belt pretensioners are designed to deploy in moder-
ate or severe frontal, near frontal collisions.
In addition, the pretensioners operate when a side collision or a roll-
over accident is detected. The pretensioners operate differently
depending on what types of air bags are equipped. For more details
about the seat belt pretensioner operation, refer to the SRS Air Bag
Deployment Criteria (P. 74).
◆ Driver Air Bag
The driver’s air bag is mounted in the steering wheel.
When air bag crash sensors
detect a frontal impact of
greater than moderate force,
the driver’s air bag inflates
quickly helping to reduce injury
mainly to the driver’s head or
chest caused by directly hitting
the steering wheel.
For more details about air bag deployment, refer to “SRS Air Bag
Deployment Criteria” (P. 7 4 ).
The driver’s dual-stage air bag controls air bag inflation in two
energy stages. During an impact of moderate severity, the driver’s
air bag deploys with lesser energy, whereas during more severe
impacts, it deploys with more energy.
Your Toyota is equipped with the following types of SRS air
bags. SRS air bags are designed to work together with the seat
belts to help to reduce injuries during an accident. The SRS air
bags are designed to provide further protection for passengers
in addition to the seat belt functions. Be sure to wear seat belts
properly.
