Toyota Yaris: How the SRS Air Bags Work / Side Air Bags
The side air bags are mounted in the outboard sides of the front seatbacks.
When the air bag crash sensors detect a side impact of greater than moderate force, the system inflates the side air bag only on the side in which the vehicle was hit. The side air bag inflates quickly to reduce injury to the driver or front passenger’s chest caused by directly hitting interior parts such as a door or window.
For more details about air bag deployment, refer to “SRS Air Bag Deployment Criteria”.
In addition, the front passenger side air bag is designed to only deploy when the front passenger occupant classification sensor detects a passenger sitting on the front passenger’s seat. For details, refer to the front passenger occupant classification system.
Front Passenger Air Bag
The front passenger air bag is mounted in the front passenger
dashboard.
The inflation mechanism for the
front passenger air bag is the
same as the driver’s air bag, as
mentioned above...
Curtain Air Bags
The curtain air bags are mounted in the front and rear window pillars, and
the roof edge along both sides.
When the air bag crash sensors detect a side impact of greater
than moderate force, the curtain air bag inflates quickly and helps to
reduce injury mainly to the rear outboard passenger’s head caused
by directly hitting interior parts such as a door or window...

Front Seat Belt Pretensioners
The front seat belt pretensioners are designed to deploy in moderate or severe frontal, near frontal collisions.
In addition, the pretensioners operate when a side collision or a rollover 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.
