1-7. Safety information
■
SRS airbag deployment conditions (SRS front airbags/SRS seat cush-
ion airbags)
●
The SRS front airbags and seat cushion airbags will deploy in the event
of an impact that exceeds the set threshold level (the level of force corre-
sponding 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 and 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, SRS seat cushion airbags and the seat belt pretensioners may not
activate together.
●
The SRS front airbags and seat cushion airbag for the front passenger
will not activate if there is no passenger sitting in the front passenger
seat. However, the SRS front airbags and seat cushion airbag for the
front passenger may deploy if luggage is put in the seat, even if the seat
is unoccupied.
●
The SRS seat cushion airbags on the front seats will not operate if the
occupant is not wearing a seat belt.
■
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 corresponding to the
impact force produced by an approximately 3300 lb. [1500 kg] vehicle collid-
ing with the vehicle cabin from a direction perpendicular to the vehicle orien-
tation at an approximate speed of 12 - 18 mph [20 - 30 km/h]).
