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 approxi-
mately 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
vehicle is very close to the designed threshold level, the SRS front air-
bags 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 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 and curtain shield air-
bags)
●
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 corre-
sponding to the impact force produced by an approximately 3300 lb.
[1500 kg] vehicle colliding with the vehicle cabin from a direction perpen-
dicular to the vehicle orientation at an approximately speed of 12 - 18
mph [20 - 30 km/h]).
●
The SRS side airbag on the passenger seat will not activate if there is no
passenger sitting in the front passenger seat. However, the side airbag
on the passenger seat may deploy if luggage is put in the seat, even if
the seat is unoccupied. (
