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.
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...
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...
Other information:
Always hang clothes on the coat
hooks and the assist grips without
hangers.
WARNING
Never hang heavy or sharp objects on the assist grips and coat hooks
Hanging heavy or sharp-ended objects such as a coat hanger from the
assist grips or coat hooks is dangerous as they can fly off and hit an occupant
in the cabin if a curtain air bag was to deploy, which could result in serious
injury or death...

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.
