1-8. Safety information n SRS airbag deployment conditions (SRS front airbags and SRS seat cushion air- bag) l The SRS front airbags and SRS seat cushion airbag 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, SRS seat cushion airbag 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 SRS passenger airbag may deploy if luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccupied.(→P. 107) n Conditions under which the SRS airbags may deploy (inflate), other than a collision (SRS front airbags and SRS seat cushion airbag) The SRS front airbags and SRS seat cushion airbag may also deploy if a serious impact occurs to the underside of your vehicle. Some examples are shown in the illustration. l Hitting a curb, edge of pavement or hard surface l Falling into or jumping over a deep hole l Landing hard or vehicle falling 142
