If the SRS airbags deploy (inflate)
●
Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
●
A loud noise and white powder will be emitted.
●
Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, and parts of the front and rear pillars and roof
side rail, may be hot for several minutes. The airbag itself may also be
hot.
●
The front windshield may crack.
■
SRS airbag deployment conditions (front airbags)
●
The front SRS airbags will deploy in the event of an impact that exceeds
the set threshold level (the level of force corresponding to a 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. (→P. 82)
