SEAT BELT TURNING LOOP ADJUSTER (Continued)
(6) Position the seat belt turning loop onto the
height adjuster on the upper inner B-pillar.
(7) Install and tighten the screw that secures the
seat belt turning loop to the height adjuster. Tighten
the screw to 40 N·m (29 ft. lbs.).
(8) Engage the lower snap features of the new trim
cover over the front outboard seat belt turning loop
and, using hand pressure, press firmly and evenly on
the top of the trim cover until it snaps into place.
SIDE CURTAIN AIRBAG
DESCRIPTION
Fig. 47 SRS Logo
Optional side curtain airbags are available for this
model when it is also equipped with dual front air-
bags. These airbags are passive, inflatable, Supple-
mental Restraint System (SRS) components, and
vehicles with this equipment can be readily identified
by a molded identification trim button with the "SRS
- AIRBAG" logo located on the headliner above each
A-pillar, and above each B-pillar on quad cab models
(Fig. 47). This system is designed to reduce injuries
to the vehicle occupants in the event of a side impact
collision.
Vehicles equipped with side curtain airbags have
two individually controlled curtain airbag units.
These airbag units are concealed and mounted above
the headliner where they are each secured to one of
the roof side rails (Fig. 48). Each folded airbag cush-
ion is contained within a long extruded plastic chan-
nel that extends along the roof rail from the A-pillar
at the front of the vehicle to just behind the B-pillar
on standard cab models, and to just behind the C-pil-
lar on quad cab models. A tether extends down the
A-pillar from the front of the airbag cushion, where it
is retained to the pillar with plastic push-in routing
clips and it is secured to the base of the A-pillar near
the belt line with a screw.

The hybrid-type inflator for each airbag is secured
to the roof rail at the rear of the airbag unit behind
the B-pillar (standard cab) or C-pillar (quad cab), and
is connected to the airbag cushion by a long tubular
manifold. The inflator bracket and the airbag cushion
channel are located with plastic push-in fasteners to
the roof rail, then secured with screws to spring nuts
located in the roof rail. A two-wire take out of the
body wire harness with a keyed and latched connec-
tor insulator connects directly to an integral recepta-
cle on the inflator initiator.
The side curtain airbag unit cannot be adjusted or
repaired and must be replaced if deployed, faulty, or
in any way damaged. Once a side curtain airbag has
been deployed, the complete airbag unit, the head-
liner, the upper A, B, and C-pillar trim, and all other
visibly damaged components must be replaced.
OPERATION
Each side curtain airbag is deployed individually
by an electrical signal generated by the left or right
Side Impact Airbag Control Module (SIACM) 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 con-
tains a small canister of highly compressed inert gas.
When the SIACM 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 con-
tainment disk in the inert gas canister. The inflator
