1-7. Safety information n SRS airbag deployment conditions (SRS front airbags) l The SRS front 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 and 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 1 Before driving 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 airbags for the front passenger will not activate if there is not a passenger sitting in the front passenger seat. However, the front airbags for the front passenger may deploy if luggage is put in the seat, even if the seat is unoccupied. n SRS airbag deployment conditions (SRS side airbags and SRS curtain shield airbags) 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 SRS curtain shield airbags will deploy in the event of vehicle roll- over. 127 LX570_U (OM60G53U)
