1-7. Safety information n Operating conditions (front airbags) l The SRS front airbags will deploy in the event of an impact that exceeds the set threshold level (the level of force corresponding to an approximately 12-18 mph [20-30 km/h] frontal collision with a fixed wall that does not move or deform). However, this threshold velocity will be considerably higher if the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact, or if the vehicle is involved in an underride collision (e.g. a collision in which the front of the vehicle "underrides", or goes under the bed of a truck, etc.). l It is possible that in some collisions where the forward deceleration of the vehicle is very close to the designed threshold level, the SRS front airbags and the seat belt pretensioners may not activate together. l The SRS front passenger airbag will not activate if there is no passenger sitting in the front passenger seat. However, the front passenger airbag may deploy if luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccupied. (→P. 124) n Operating conditions (side airbags & curtain shield airbags) The SRS side airbags & 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 3307 lb. [1500 kg] vehicle colliding with the vehicle cabin from a direction perpendicular to the vehicle orientation at an approximately speed of 12-18 mph [20-30 km/ h]). n Operating conditions (side airbags) The SRS side airbag on the passenger seat will activate even if there is no passenger sitting in the front passenger seat. (→P. 124) n Operating conditions (curtain shield airbags) The SRS curtain shield airbags are designed to inflate when the passenger compartment is subjected to a severe impact from the side or vehicle rollover. Depending on the conditions and type of accident, there are times when the curtain shield airbags may deploy (inflate) in a front impact. 114
