1-1. For safe use
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 per-
pendicular to the vehicle orientation at an
approximate speed of 12 - 18 mph [20 -
30 km/h]).
● Both SRS curtain shield airbags may
deploy in the event of a severe side colli-
sion.
Both SRS curtain shield airbags will
●
deploy in the event of vehicle rollover.
Both SRS curtain shield airbags may also
●
deploy in the event of a severe frontal col-
lision.
■ Conditions under which the SRS air-
bags may deploy (inflate), other than a
collision
The SRS front airbags and SRS curtain
shield airbags 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
surface
Falling into or jumping over a deep hole
●
Landing hard or falling
●
The SRS curtain shield airbags may also
deploy under the situations shown in the
illustration.
The angle of vehicle tip-up is marginal.
●
● The vehicle skids and hits a curb stone.
■ Types of collisions that may not deploy
the SRS airbags (SRS front airbags)
The SRS front airbags do not generally
inflate if the vehicle is involved in a side or
rear collision, if it rolls over, or if it is involved
in a low-speed frontal collision. But, when-
ever a collision of any type causes sufficient
forward deceleration of the vehicle, deploy-
ment of the SRS front airbags may occur.
● Collision from the side
Collision from the rear
●
Vehicle rollover
●
Types of collisions that may not deploy
■
the SRS airbags (SRS side and curtain
shield airbags)
The SRS side and curtain shield airbags
may not activate if the vehicle is subjected
to a collision from the side at certain angles,
or a collision to the side of the vehicle body
other than the passenger compartment.
