(5) With driver airbag removed, pick a corner and
push down on the inflator or latch hook mounting
plate until the latch hooks push out of the driver air-

INSTALLATION
(1) Place driver airbag into new driver airbag trim
cover. Be careful not to pinch airbag cushion between
latch hook mounting plate and cover.
(2) Push down on the latch hook mounting plate
and guide the latch hooks into the slots on the driver
airbag trim cover.
(3) Make sure that the horn wire leads are prop-
erly routed (Fig. 23).
(4) Once all the latch hooks have been started,
grasp the driver airbag with both hands. Apply pres-
sure with thumbs on front of airbag and with finger-
tips grasping the sides of the airbag trim cover, push
thumbs while pulling fingertips, seating the latch
hooks in the latch windows (Fig. 24).

KNEE BLOCKER AIRBAG
DESCRIPTION
The Knee Blocker Airbag (Fig. 25) and (Fig. 26) is
located on the driver side of the vehicle beneath the
instrument panel steering column outer cover (Fig.
27).
The knee blocker airbag includes one reaction plate
and one load plate, within which the cushion and
inflator are mounted and sealed. Following a knee
blocker airbag deployment, the knee blocker airbag
and instrument panel assembly must be replaced.
Refer to the proper Body Diagnostic Procedures man-
ual for diagnosis and testing.
OPERATION
The knee blocker airbag is equipped with a single
inflator. When the ORC sends the proper electrical
signals to the initiator, the electrical energy gener-
ates enough heat to initiate a small pyrotechnic
charge which, in turn ignites chemical pellets within
the inflator. Once ignited, these chemical pellets burn
rapidly and produce a large quantity of inert gas.
The inflator is sealed to the back of the airbag hous-
ing and a diffuser in the inflator directs all of the
inert gas into the airbag cushion, causing the cushion
to inflate. As the cushion inflates, the knee blocker
airbag trim deploy. Following an airbag deployment,
the airbag cushion quickly deflates by venting the

inert gas towards the instrument panel through vent
holes within the fabric used to construct the back
panel of the airbag cushion.
Some of the chemicals used to create the inert gas
may be considered hazardous while in their solid
state before they are burned, but they are securely
sealed within the airbag inflator. Typically, the poten-
tially hazardous chemicals are burned during an air-
bag deployment event.
The inert gas that is produced when the chemicals
are burned is harmless. However, a small amount of
residue from the burned chemicals may cause some
temporary discomfort if it contacts the skin, eyes, or
breathing passages. If skin or eye irritation is noted,
rinse the affected area with plenty of cool, clean
water. If breathing passages are irritated, move to
another area where there is plenty of clean, fresh air
to breath. If the irritation is not alleviated by these
actions, contact a physician.
