■

SRS airbag deployment conditions (SRS front airbags)

●

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 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.).

●

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.

●

The SRS front passenger airbag will not activate if there is no passenger sitting

in the front passenger seat. However, the SRS front passenger airbag may

deploy if luggage is put in the seat, or the seat belt is fastened, even if the seat is

unoccupied. (

SRS airbag deployment conditions (SRS side airbags and curtain shield airbags)

The SRS side and 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]).
