The second row seats have lower anchors for each
rear outboard seating position (Fig. 8). These anchors
are welded to the seat cushion frame. They are each
accessed from the front of their respective seats, at
each side where the seat back meets the seat cush-
ion. These lower anchors cannot be adjusted or
repaired and, if faulty or damaged, the seat must be
replaced as a unit.
WARNING: During, and following, any child restraint
anchor service, due to impact event or vehicle
repair, carefully inspect all mounting hardware,
tether straps and anchors for proper installation,
operation, or damage. If a child restraint anchor is
found damaged in any way, the anchor must be
replaced with the seat assembly. Failure to do so
could result in personal injury or death.
REAR SEAT DELETE
If the vehicle is ordered without rear seats (rear
seat delete), then there will be a tether strap
included. This is to be looped under the second seat
anchor and then extended forward (Fig. 9) to clip to
the tether strap of the child seat in the front passen-
ger seat (Fig. 10). There will be no lower anchor
loops for child seat anchoring in the front passenger
seat. Use the seat belt for lower child seat attach-
ment in this instance.
OPERATION
See the owner's manual in the vehicle glove box for
more information on the proper use of all of the fac-
tory-installed child restraint anchors.
CLOCKSPRING
DESCRIPTION
The clockspring is mounted on the steering column
behind the steering wheel. It is used to maintain a
continuous electrical circuit between the wiring har-
ness and the drivers airbag.
The clockspring assembly is secured with two inte-
gral plastic latches onto the upper steering column
housing near the top of the steering column behind
the steering wheel. The clockspring consists of a flat,
round molded plastic case with a stubby tail that
hangs below the steering column. The tail contains
two connectors that face toward the instrument
panel. Within the plastic case is a spool-like molded
plastic rotor with a large exposed hub and several
plastic rollers.
A rubber bumper block is located on each side of
the tower formation that contains the connector
receptacle and pigtail wires on the upper surface of
the rotor hub. The lower surface of the rotor hub has
a molded plastic turn signal cancel cam with a single
lobe that is integral to the rotor. Within the plastic
case and wound around the rotor spool is a long rib-
bon-like tape that consists of several thin copper wire
leads sandwiched between two thin plastic mem-
branes. The outer end of the tape terminates at the
connector receptacles that face the instrument panel,
while the inner end of the tape terminates at the pig-
tail wires and connector receptacle on the hub of the
clockspring rotor that face the steering wheel.

Service replacement clocksprings are shipped pre-
centered and with a molded plastic shield that snaps
onto the rotor over the release button. The release
button secures the centered clockspring rotor to the
clockspring case and the shield prevents the release
button from being inadvertently depressed during
shipment and handling, but the shield must be
removed from the clockspring after it is installed on
the steering column (Refer to 8 - ELECTRICAL/RE-
STRAINTS/CLOCKSPRING - STANDARD PROCE-
DURE).
The clockspring cannot be repaired. If the clock-
spring is faulty, damaged, or if the driver airbag has
been deployed, the clockspring must be replaced.
OPERATION
The clockspring is a mechanical electrical circuit
component that is used to provide continuous electri-
cal continuity between the fixed instrument panel
wire harness and the electrical components mounted
on or in the rotating steering wheel. The rotating
electrical components include the driver airbag, the
horn switch, the speed control switches, and the
remote radio switches, if the vehicle is so equipped.
The clockspring case is positioned and secured to the
upper steering column housing near the top of the
steering column. The connector receptacles on the
tail of the clockspring case connect the clockspring to
the vehicle electrical system through two connectors
from the instrument panel wire harness.
The clockspring rotor is movable and is keyed by
the tower formation that is molded onto the upper
surface of the rotor hub to an opening that is cast
into the steering wheel armature. Rubber bumper
blocks on either side of the clockspring tower forma-
tion eliminate contact noise between the clockspring
tower and the steering wheel. The lobe of the turn
signal cancel cam on the lower surface of the clock-
spring rotor hub contacts a turn signal cancel actua-
tor of the multi-function switch to provide automatic
turn signal cancellation. The yellow or black-sleeved
pigtail wires on the upper surface of the clockspring
rotor connect the clockspring to the driver airbag,
while a steering wheel wire harness connects the
connector receptacle on the upper surface of the
clockspring rotor to the horn switch and, if the vehi-
cle is so equipped, to the optional speed control
switches and remote radio switches on the steering
wheel.
The clockspring tape has travel limits and can be
damaged by being wound too tightly during full stop-
to-stop steering wheel rotation. To prevent this from
occurring, the clockspring is centered when it is
installed on the steering column. Centering the clock-
spring indexes the clockspring tape to the movable
steering components so that the tape can operatewithin its designed travel limits. However, if the
clockspring is removed from the steering column or if
the steering shaft is disconnected from the steering
gear, the clockspring spool can change position rela-
tive to the movable steering components and must be
re-centered following completion of the service or the
tape may be damaged (Refer to 8 - ELECTRICAL/
RESTRAINTS/CLOCKSPRING - STANDARD PRO-
CEDURE).
Service replacement clocksprings are shipped pre-
centered and with a plastic shield installed over the
clockspring release button. This shield should not be
removed and the release button should not be
depressed until the clockspring has been installed on
the steering column. If the release button is
depressed before the clockspring is installed on a
steering column, the clockspring centering procedure
must be performed (Refer to 8 - ELECTRICAL/RE-
STRAINTS/CLOCKSPRING - STANDARD PROCE-
DURE).
STANDARD PROCEDURE - CLOCKSPRING
CENTERING
If the rotating tape (wire coil) in the clockspring is
not positioned properly with the steering wheel and
the front wheels, the clockspring may fail. The fol-
lowing procedure MUST BE USED to center the

CURTAIN AIRBAG
DESCRIPTION
Curtain Airbags (Fig. 11) are available when it is
also equipped with dual front airbags. These airbags
are passive and inflatable, Supplemental Restraint
System (SRS) components, and vehicles with this
equipment can be readily identified by a molded
identification trim button with the ªSRS - AIRBAGº
logo (Fig. 12) located on the B-pillar and C-pillar
upper trim panels. This system is designed to reduce
injuries to the vehicle occupants in the event of a
side impact collision.
Curtain airbags have two individually controlled
curtain airbag units. These airbag units are con-
cealed and mounted above the headliner where they
are each secured to one of the roof side rails (Fig.
13). Each airbag cushion is contained within a fabric
wrap that extends along the roof rail from the A-pil-
lar at the front of the vehicle to just behind the
D-pillar at the rear of the vehicle. One tether extends
down the A-pillar from the front of the airbag cush-
ion, and a second tether extends to the roof rail at
the D-pillar. The end of the A-pillar tether is secured
to a slot in the sheet metal with a metal hook
retained by a bolt. The D-pillar tether is attached to
the d-pillar.

The hybrid-type inflator for each airbag is secured
to the roof rail just behind the C-pillar. The inflator
bracket and the airbag cushion are secured with both
plastic push-in fasteners and screws to the roof rail.
A short pigtail wire harness connects the curtain air-
bag inflator to the body wire harness.
The curtain airbag cannot be adjusted or repaired
and must be replaced if deployed, faulty, or in any
way damaged. Once a curtain airbag has been
deployed, the complete airbag unit (Refer to 8 -
ELECTRICAL/RESTRAINTS - STANDARD PROCE-
DURE - SERVICE AFTER AN AIRBAG DEPLOY-
MENT), headliner, upper A/B/C and D-pillar trim,
and all other visibly damaged components must be
replaced (Refer to Section 23 - BODY/INTERIOR for
complete body interior Removal and Installation pro-
cedures). Refer to the appropriate diagnostic informa-
tion for complete diagnosis and testing or the curtain
airbags.The curtain airbags also contain Head Impact
Counter Measures (Fig. 14). These injection molded
plastic components help to reduce the likelihood of
injury or death in the event of a side impact event.
They are attached to the curtain airbag and are also
used to mount the curtain to the inside roof rail.
Their purpose is to maintain a flat surface in which
the deployed airbag to be pressed against when inte-
rior occupants/forces are pushing outwards.
OPERATION
Each curtain airbag is deployed individually by an
electrical signal generated by the Occupant Restraint
Controller (ORC) to which it is connected through
left or right curtain airbag line 1 and line 2 (or
squib) circuits. The hybrid-type inflator assembly for
each airbag contains a small canister of highly com-
pressed inert gas. When the ORC sends the proper
electrical signal to the airbag inflator, the electrical
energy creates enough heat to ignite chemical pellets
within the inflator. Once ignited, these chemicals
burn rapidly and produce the pressure necessary to
rupture a containment disk in the inert gas canister.
The inflator and inert gas canister are sealed and
connected to a tubular manifold so that all of the
released gas is directed into the folded curtain airbag
cushion, causing the cushion to inflate.

DRIVER AIRBAG
DESCRIPTION
The injection molded, thermoplastic driver airbag
protective trim cover is the most visible part of the
driver airbag. The driver airbag is located in the cen-
ter of the steering wheel, where it is secured to the
steering wheel armature. Concealed beneath the
driver airbag trim cover are the horn switch, thefolded airbag cushion, the airbag cushion retainer,
the airbag housing, the airbag inflator, and the
retainers that secure the inflator to the airbag hous-
ing. The airbag cushion, housing, and inflator are
secured within an integral receptacle molded into the
back of the trim cover.
The resistive membrane-type horn switch is
secured with heat stakes to the inside surface of the
driver airbag trim cover, between the trim cover and
the folded airbag cushion. The horn switch ground
pigtail wire has a female spade terminal connector
that receives a path to ground through a male spade
terminal that is integral to the driver airbag housing
stamping and is located near the upper right corner
on the back of the housing. The horn switch feed pig-
tail wire has a white, molded plastic insulator that is
secured by an integral retainer to a mounting hole
located near the lower left corner on the back of the
housing, and is connected to the vehicle electrical
system through a take out and connector of the steer-
ing wheel wire harness.
The airbag is a multistage unit that deploys with
less force than those previously used. The airbag
inflator is a dual-initiator, non-azide, pyrotechnic-
type unit with four mounting studs and is secured to
the stamped metal airbag housing using four hex
nuts with washers. Two keyed and color-coded con-
nector receptacles on the driver airbag inflator con-
nect the two inflator initiators to the vehicle
electrical system through two yellow or black-jack-
eted, two-wire pigtail harnesses of the clockspring.
The driver airbag, trim cover, and horn switch unit
cannot be repaired, and must be replaced if deployed
or in any way damaged.
OPERATION
The Driver Airbag Trim Cover contains the horn
switch, inflator device, and a fabric bag. The driver
airbag trim cover/horn switch is not serviced sepa-
rately from the driver airbag components.
