1-7. Safety information n Operating conditions (front airbags) l The SRS front airbags will deploy if the severity of the frontal impact is above the designed threshold level, comparable to an approximate 15 mph (25 km/h) collision when the vehicle impacts straight into a fixed barrier 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 vehi- cle 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 not 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. 90) n Operating conditions (side and curtain shield airbags) l The SRS side airbags and curtain shield airbags are designed to inflate when the passenger compartment is subjected to a severe impact from the side. l The SRS side airbag on the passenger seat will not activate if there is no passen- ger sitting in the front passenger seat. However, the side airbag on the passenger seat may deploy, if luggage is put in the seat, even if the seat is unoccupied. (→P. 90) 80
