units. A large quantity of nontoxic gas is generated to
inflate the front airbags. Different airbag inflation rates
are possible, these rates are determined by the front
airbag control module based on collision severity. The
steering wheel hub trim cover and the upper right side
of the instrument panel separate and fold out of the
way as the bags inflate to their full size. The bags fully
inflate in about 30–70 milliseconds. This is about half
of the time it takes to blink your eyes. The bags then
quickly deflate while helping to restrain the driver and
front passenger.
The driver front airbag gas is vented through the
airbag material towards the instrument panel. The
passenger front airbag gas is vented through the
airbag material on the sides of the airbag. In this way,
the airbags do not interfere with your control of the
vehicle.
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 41
• The Side Impact SRS Window Bags are designed to
activate only in certain side collisions. When the airbag
control module (ACM), along with the remote side
impact sensors detects a side impact collision requir-
ing the window bags to inflate, it signals the inflators
on the crash side of the vehicle. A quantity of nontoxic
gas is generated to inflate the window bag. The
inflating window bag pushes the outside edge of the
headliner out of the way and covers the window. The
airbag inflates in about 30 milliseconds (about one
quarter of the time it takes to blink your eyes) with
enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
where the window bag inflates. This especially applies
to children. The window bag is only about 3
(9 cm) thick when it is inflated.
• The Knee Impact Bolsters help protect the knees of
the driver and the front passenger's, and position
everyone for the best interaction with the front airbag.
