NOTICE: All lap, shoulder and seat assembly fasteners are important attaching parts in that they could
affect the performance of vital components and systems, and/or could result in major repair expense. They must
be replaced with one of the same part number or with an equivalent part if replacement becomes necessary. Do
not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during
reassembly to assure proper retention of these parts.

LAP AND SHOULDER BELTS
The seat belts incorporate a 4-to-8 second fasten
seat belt reminder lamp and sound signal designed to
remind the driver if the lap and shoulder belts are not
fastened when the ignition is turned to the on position.
If the driver's seat belt
is buckled,
the alarm will not
operate; however, the fasten seat belt reminder lamp
will stay on for a 4-to-8 second period. If the driver's
seat belt is
not buckled,
the reminder lamp and
sound signal will automatically shut off after a 4-to-8
second interval. To diagnose a system failure, refer to
Seat Belt Reminder Lamp/Alarm Diagnosis Chart
(Fig. 1).
The single loop belt system consists of a single
continuous length of webbing. The webbing is routed
from the anchor (at the rocker panel), through a
self-locking latch plate (at the buckle), around the
guide assembly (at the top of the center pillar or
quarter panel) and into a retractor in the lower area of
the center pillar or quarter inner. The emergency
locking feature of the retractor remains unlocked to
allow free movement of the occupant's upper body
while the vehicle is being operated. When the vehicle
decelerates or changes direction abruptly, the single
loop belt(s) is locked in position by a pendulum that
causes a locking bar to engage a cog of the retractor
mechanism.
The retractor has a comfort lock feature that
allows the occupant to adjust the shoulder belt for
proper fit and comfort. When engaged, the comfort
lock prevents full retraction of the webbing to eliminate
occupant discomfort due to webbing load on the
shoulder. The occupant can readjust the comfort lock
during vehicle operation as described below. Whenever
the occupant's door is opened, the comfort lock is
automatically unlocked so the webbing can fully
retract to the stowed position. This is controlled by the
comfort lock plunger located at the lower front side of
the center or lock pillar.
When servicing or replacing lap and shoulder
belts of the single loop system, refer to the following
precautionary items:
1. Lap and shoulder belts will be serviced as follows:
a Retractor portion of lap and shoulder belt
for passenger and driver,
b Buckle portion of seat lap belt for passenger
and driver.
2. Keep sharp edges and damaging objects away
from belts.
3. Avoid bending or damaging any portion of the
belt buckle or latch plate.
4. Do not bleach or dye belt webbing (clean with
mild soap solution and water).
5. When installing lap or shoulder belt anchor bolts,
start bolt by hand to assure that bolt is threaded
straight.
NOTICE: See NOTICE on page 9J-1 of this
section.
6. Do not attempt repairs on lap or shoulder belt
retractor mechanisms or belt retractor covers.
Replace with new service replacement parts.
Refer to Figures 2 through 5 and tighten all seat
and shoulder belt anchor bolts as specified.

Requirements
jjTj
Important
