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.)

SRS equipment

Types of collision

A severe frontal/near frontal collision

A severe side collision*1

A roll-over/near roll-over*2

A rear collision

Front seat belt pretensioner

X (both sides)

X (impact side only)

X (both sides)

No air bag and front seat belt pretensioner will be activated in a rear collision.

Driver air bag


Front passenger air bag


Side air bag

X (impact side only)

Curtain air bag

X (both sides)

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

  1. In a side collision, the seat belt pretensioners and the side/curtain air bags deploy (only on the side in which the collision occurs).

  2. (European models)

    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.
