INSPECTION
Seat belts and attaching parts can affect the vital components and
systems of a vehicle. Therefore, they should be inspected carefully
and replaced with genuine parts only.
Seat belt
The seat belt webbing or strap should be free from damage.
Fully extend the seat belt to make sure there are no twists or tears
in it.
Retractor assembly
Let the seat belt retract fully to confirm its easy retraction.
The retractor assembly should lock webbing when pulled quickly.
The retractor assembly should lock webbing even when tilted
(approx. 15) toward the fore and aft or right and left directions.
Anchor bolt
Inspect all seat belt anchor bolts to verify that they are secure.
All anchor bolts should be secure and torqued to specification.
Belt latch
Belt latch should be secure when latched.
Inspect the seat belt buckle, ensuring that it locks and unlocks
easily.
After buckling the seat belt, tug sharply on the belt, checking that
the buckle remains locked.
Warning system
Check driver side seat belt strap switch for continuity by using ohm-
meter.
Without inserted buckle tongue to buckle catch:
Terminal ªAº and ªBº: Continuity
With inserted buckle tongue to buckle catch:
Terminal ªAº and ªBº: No continuity ()
As to seat belts with ALR (other than driver side seat belt), check
them as follows in addition to above check.
With vehicle at stop, pull seat belt all the way out, let it retract a
little and try to pull it. It should not be pulled out, that is, it should
be locked where retracted.
Let seat belt retract to its original state. Next, pull it half way out,
let it retract a little and try to pull it again. It should be pulled out
smoothly, that is it should not be locked at this time.

AIR BAG SYSTEM 10B-3
GENERAL DESCRIPTION
With the air bag system which includes air bags for both the driver's
and passenger's sides as well as the seat belt pretensioners (if
equipped), the sag of the seat belt is taken up, the driver air bag (in-
flator) module is deployed from the center of the steering column
and the passenger air bag (inflator) module from the top of the
instrument panel in front of the front passenger seat in occurrence
of a front collision with an impact larger than a certain set value to
supplement protection offered by the driver and front passenger
seat belts.
The air bag system is designed to activate only in severe frontal col-
lisions. It is not designed to activate in rear impacts, side impacts,
rollovers, or minor frontal collisions, since it would offer no protec-
tion in those types of accidents.
