10. SEAT BELTS
The front and outer rear seats are equipped with
lap/sash inertia reel seat belts, which are designed to
lock with any sudden change in vehicle motion.
The centre rear seat is equipped with a manually
adjustable lap seat belt.
Child restraint anchorages are located on the
parcel shelf behind the rear seat on Sedan models and
at the rear of the lugg age compartment floor on
Hatchback models. These anchorages must be used if
a child's seat or capsule is installed to the vehicle. The
anchorages should not be used for adult scat bells or
harnesses.
The seat belts should be periodically inspected as
described below. Any seat belt assembly that is worn
or damaged, or has been subjected to abnormal
loadings in a collision, should be renewed as a
complete assembly.
Only mild soap and water should be used to clean
the webbing. Contamination wi th polish, oil, bleaches
and other chemicals should be avoided.
TO INSPECT
(1) Check the seat belt webbing for fraying, cuts,
burns or other damage. On inertia reel belts, slowly
pull the belt from the reel to allow the entire length to
be examined. If the webbing is damaged or worn,
renew the seat belt assembly.
Check the seat belt webbing for fraying, cuts, burns or
other damage.
Ensure that the belts are not twisted.
Check all retaining nuts and bolts for secu-
rity.
Inspect the belt buckles for correct and
secure engagement. If the buckles are damaged or do
not function correctly, renew the seat belt assembly. On inertia reel seat belts, check the retractor
mechanism as follows:
Pull the belt slowly from the reel and check
for smooth operation. Release the belt and ensure that
it retracts fully.
Pull the belt rapidly from the reel. The reel
should lock.
Drive the vehicle at walking pace and at-
tempt to withdraw the belt slowly while braking
sharply. The reel should lock. If the retractor mechanism does not function
correctly, renew the seat belt assembly.

12. VEHICLE CLEANING
CLEANING THE EXTERIOR
In order to remove dirt and road grime and thus
preserve paint finish, vehicles in continuous use
should be washed at least once a week.
Before washing the paintwork, it is good policy to
first hose all dirt from the underbody and clean out
the drain holes in the doors and sill panels.
Hose the vehicle to remove as much grit as
possible and wash using a clean chamois or sponge,
ensuring that the chamois or sponge is free from dirt
or grit which could scratch the paint surface.
Avoid washing the vehicle in bright sunlight with
high temperature as this will give the paintwork a
streaky watermarked finish.
If necessary, wash the vehicle using a reputable
brand Wash and Wax liquid. The Wash and Wax
liquid will restore the paint luster and leave the
paintwork with a protective coating of wax.
After a period it may become necessary to polish
the vehicle in order to remove built up foreign matter
and give the paintwork maximum protection from
industrial fall-out and salt from sea air etc. Before
polishing the paintwork, always wash the surface to
remove as much road grime as possible. When
polishing follow the polishing instructions which come
with the polish.
NOTE: Grease, oil or tar on the paint
surface can be removed with a little kerosene
or white spirits. To prevent staining, wash
and polish the affected area as soon as the
grease, oil or tar is removed.
CLEANING VINYL TRIM
To maintain the vinyl interior trim in good
condition it should be regularly vacuumed to remove
loose dirt and then wiped with a dry or damp cloth.
If the trim is soiled or stained, the following
cleaning procedure is recommended:
Using warm water, cheese cloth and a mild
soap, thoroughly wash the affected areas.
Repeat the operation using damp cheese
cloth only.
To complete the cleaning operation wipe the
trim over with a dry piece of cheese cloth.
NOTE: If the interior trim is badly soiled or
stained, wash with a reputable brand of
upholstery cleaner care fully following the
makers instructions.
CLEANING CLOTH TRIM
Loose dirt and dust on cloth trim should be
removed with a vacuum cleaner or a very soft brush.
Do not use a whisk brush or any other type of coarse
brush or damage to the cloth could result. If the fabric
is soiled the following cl eaning procedure is recom-
mended.
Sponge the fabric ligh tly with warm water
containing a little detergen t and household ammonia.
After sponging, rub the fabric lightly. If
soiling is still apparent, re peat the sponging operation.
Use a clean dry cloth to soak up excess fluid.
