position sensor, driver's seat belt buckle switch, front passenger occupant
classification system, AIR BAG ON and AIR BAG OFF indicator lights, front
passenger's seat position sensor (Regular Cab models), front passenger's

n If the SRS airbags deploy (inflate)
Bruising and slight abrasions may result from contact with a deploying
l
(inflating) SRS airbag.
A loud noise and white powder will be emitted.
l
l 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.
l
Operating conditions (front airbags)
n
The SRS front airbags will deploy if the severity of the frontal impact is
l
above the designed threshold level, comparable to an approximate 15
mph (25 km/h) collision when the vehicle impacts straight into a fixed bar-
rier 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
l
vehicle is very close to the designed threshold level, the SRS front air-
bags and the seat belt pretensioners may not activate together.
