SRS airbag deployment conditions (SRS front airbags)
■
The SRS front airbags 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 in the following situa-
tions:
• 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 pretension-
●
ers will activate.
The SRS front airbags for the front passenger will not activate if there is no passen-
●
ger sitting in the front passenger seat. However, the SRS front airbags for the front
passenger may deploy if luggage is put in the seat, even if the seat is unoccupied.

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 colli-
●
sion.
Conditions under which the SRS airbags may deploy (inflate), other than a collision
■
The SRS front airbags and SRS curtain shield airbag may also deploy if a serious
impact occurs to the underside of your vehicle. Some examples are shown in the
illustration.
Hitting a curb, edge of pavement or hard

Falling into or jumping over a deep hole
