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 airbags will not activate, if there is no passenger sitting in the front passenger seat. However, the front passenger airbag may deploy, if heavy luggage is put, even if the seat is unoccupied. (→P. 72) 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 front side airbag on the passenger seat will not activate, if there is no passenger sitting in the front passenger seat. However, the front side airbag on the passenger seat may deploy, if heavy luggage is put, even if the seat is unoccupied. (→P. 72) n Conditions under which the SRS airbags may deploy (inflate), other than a colli- sion 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. 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 62
