
SRS airbag deployment conditions (SRS side airbags and curtain shield air-
bags)
The SRS side airbags and curtain shield airbags will deploy in the event of
an impact that exceeds the set threshold level (the level of force correspond-
ing 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]).

Conditions under which the SRS airbags may deploy (inflate), other than a
collision (SRS front airbags)
The SRS front airbags may also deploy if a serious impact occurs to the
underside of your vehicle. Some examples are shown in the illustration.

Types of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags are generally not designed to 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 forward deceleration of the vehicle, deployment of the SRS front
airbags may occur.
