SRS airbag deployment conditions (SRS front airbags)

■
The SRS front airbags will deploy in the event of an impact that exceeds the set thresh-
●
old 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 in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move
or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle "underrides", or goes under, the bed of a truck
Depending on the type of collision, it is possible that only the seat belt pretensioners will
●
activate.
The SRS front airbags for the front passenger will not activate if there is no passenger
●
sitting in the front passenger seat. However, the SRS front airbags for the front passen-
ger may deploy if luggage is put in the seat, even if the seat is unoccupied. (P. 47)

SRS airbag deployment conditions (SRS side 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 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]).
The SRS curtain shield airbags may also deploy in the event of a severe frontal collision.

occurs to the underside of your vehicle. Some examples are shown in the illustration.
