Toyota Yaris: SRS Air Bags / SRS Air Bag Deployment Criteria

Toyota Yaris XP210 (2020-2022) Owner's Manual / Essential Safety Equipment / SRS Air Bags / SRS Air Bag Deployment Criteria

This chart indicates the applicable SRS equipment that will deploy depending on the type of collision.

(The illustrations are the representative cases of collisions.)

Toyota Yaris. SRS Air Bag Deployment Criteria

X:The SRS air bag equipment is designed to deploy in a collision.

* 1: The front passenger front and side air bags and the seat belt pretensioner are designed to deploy when the front passenger occupant classification sensor detects a passenger sitting on the front passenger’s seat.

* 2: In a side collision, the seat belt pretensioners and the side/curtain air bags deploy.

* 3: In a roll-over accident, the seat belt pretensioners and the curtain air bags deploy.

In a frontal offset collision, the equipped air bags and pretensioners may all deploy depending on the direction, angle, and rate of impact.
