SRS airbag deployment conditions (SRS side and curtain shield airbags)
The SRS side and curtain shield airbags will deploy in the event of an impact that
exceeds the set threshold level (the level of force corresponding to the impact
force produced by an approximately 1500 kg [3300 lb.] vehicle colliding with the
vehicle cabin from a direction perpendicular to the vehicle orientation at an
approximate speed of 20 - 30 km/h [12 - 18 mph]).
The SRS side and curtain shield airbags will deploy in the event of a severe frontal
collision.
Conditions under which the SRS airbags may deploy (inflate), other than a collision
(SRS front airbags, SRS curtain shield airbag and SRS seat cushion airbag)
The SRS front airbags, SRS curtain shield airbag and SRS seat cushion airbag may
also deploy if a serious impact occurs to the underside of your vehicle. Some exam-
ples are shown in the illustration.
Hitting a curb, edge of pavement or hard
surface
Falling into or jumping over a deep hole
Landing hard or falling
Types of collisions that may not deploy the SRS airbags (SRS front airbags and SRS
seat cushion airbag)
The SRS front airbags and SRS seat cushion airbag do not generally inflate if the
vehicle is involved in a side or rear collision, if it rolls over, or if it is involved in a low-
speed frontal collision. But, whenever a collision of any type causes sufficient for-
ward deceleration of the vehicle, deployment of the SRS front airbags and SRS seat
cushion airbag may occur.
Collision from the side
Collision from the rear
Vehicle rollover
