Safety information n SRS airbag deployment conditions (SRS side airbags and SRS curtain shield air- bags) l The SRS side airbags and SRS 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 3300 lb. [1500 kg] vehicle colliding with the vehicle cabin from a direction perpendicular to the vehicle orientation at an approximate speed of 12 - 18 mph [20 - 30 km/h]). l The front SRS side airbag on the passenger seat will not activate if there is no passenger sitting in the front passenger seat. However, the front SRS side airbag on the passenger seat may deploy if luggage is put in the seat, even if the seat is unoccupied. (→P. 92) n Types of collisions that may not deploy the SRS airbag (SRS front airbags and SRS seat cushion airbag) The SRS front airbags and SRS seat cushion airbag 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 and SRS seat cushion airbag may occur. l Collision from the side l Collision from the rear l Vehicle rollover 126
