342 Vehicle Care
Dust and loose dirt that collect on
interior fabric should be removed
often with a vacuum cleaner or soft
bristle brush. Wipe vinyl or leather
trim regularly with a clean, damp
cloth. Normal trim soils, spots or
stains can be cleaned with these
cleaners.
Remember these basic steps before
cleaning:
.Remove stains as quickly as
possible before they
become "set".
. Use a clean cloth or sponge,
and change to a clean area
often. A soft brush maybe used
if stains persist.
. Use solvent-type cleaners only
in a well ventilated area: also, do
not saturate the stained area.
. If a ring forms after spot
cleaning, clean the entire area
immediately.
. Follow specific instructions on
cleaner labels.General Cleaning of Soiled or
Water Spotted Fabric Type
Trim with Foam Type Cleaner
Vacuum the area thoroughly to
remove any loose dirt.
Always clean a whole trim panel or
section. Mask surrounding trim
along stitch or welt lines.
Use suds on a clean sponge. Do
not brush wet suede. Do not
saturate the material or rub it
harshly. Immediately after cleaning,
remove suds with a sponge and
rinse with a clean wet sponge. Wipe
off remaining residue with a slightly
damp absorbent towel or cloth.
Important —Immediately after
wiping, force-dry the fabric with an
air hose. A heat dryer or heat lamp
may be used. Use caution with a
heat dryer or lamp to help prevent
damage.
When trim materials with a sheen or
luster finish are dry, wipe the fabric
lightly with a soft, dry, clean cloth to
restore its sheen or luster. For suede, raise nap with dry scrub
brush and vacuum to remove any
final traces of residue.Spot Cleaning Fabric Type
Trim with Solvent Type Cleaner
Before trying to remove a spot or
stain from fabric, try to find out the
type and age of the spot or stain.
Some spots or stains can be
removed with water or a mild soap
solution. Spots or stains should
always be removed as soon as
possible.
Some types of stains or soilage,
such as lipstick, inks and grease,
are very difficult (sometimes
impossible) to remove completely.
When cleaning this type of stain or
soilage, be sure not to enlarge the
soiled area.
.
Gently scrape excess stain from
the trim material with a clean,
dull knife or scraper. Use very
little cleaner, light pressure, and
clean cloths (preferably
cheesecloth). Cleaning should
start at the outside of the stain

Vehicle Care 343
"feathering" towards the center.
Keep changing to a clean
section of cloth.
. When you clean a stain from
fabric, immediately dry the area
with an air hose, heat dryer,
or heat lamp to help prevent a
cleaning ring. (Use caution with
heat dryer or lamp to help
prevent fabric damage.)
. If a ring forms, immediately
repeat the cleaning operation
over a slightly larger area with
emphasis on "feathering"
towards its center. If a ring still
remains, mask off surrounding
trim sections and clean the
entire soiled area with foam type
cleaner.
See “Removal of Specific
Stains.”
Removal of Specific Stains
Greasy or Oily Stains –Includes
grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing
gum, cosmetic creams, vegetable
oils, wax crayon, tar and asphalts. .
Carefully scrape off excess
stain; then use solvent type
cleaner.
. Shoe polish, wax crayons, tar
and asphalts will stain if left on
trim; they should be removed as
soon as possible. Use care as
cleaner will dissolve them and
may cause them to "bleed".
Non-Greasy Stains –Includes
catsup, coffee (black), egg, fruit,
fruit juice, milk, soft drinks, wine,
vomit and blood.
. Carefully scrape off excess
stain; then sponge the stain with
cool water.
. If a stain remains, use
Multi-Purpose Powdered
Cleaner (Foam type) as
previously described.
. If an odor lingers after cleaning
vomit or urine, treat the area
with a water-baking soda
solution: 5 milliliters (1 teaspoon)
of baking soda to 250 milliliters
(1 cup) of lukewarm water. .
Finally, if needed, clean lightly
with Fabric Cleaner
(Solvent type).
Combination Stains –Includes
candy, ice cream, mayonnaise, chili
sauce and unknown stains.
. Carefully scrape off excess
stain; then clean with cool water
and allow to dry.
. If stain remains, clean it with
Fabric Cleaner (Solvent type).
Cleaning Vinyl Trim
Ordinary soilage can be removed
from vinyl or leather with warm
water and mild soap, such as
saddle soap or oil soap, or an
equivalent.
.Apply a small amount of soap
solution and let it soak for a few
minutes to loosen dirt; then, rub
briskly with a clean, damp cloth
to remove dirt and traces of
soap. This may be done several
times, if needed.
. Soilage such as tars, asphalts,
shoe polish, etc., will stain if left
on trim. They should be wiped

maintenance schedule is not
followed, or is improperly carried
out, no amount of correct vehicle
operation will prevent malfunction.
If vehicle application, operation and
preventive maintenance schedules
and procedures are followed and
properly carried out, the life of the
vehicle will be greatly extended.
For example, regular attention to the
engine oil is essential. The oil level
must be periodically checked and oil
added whenever needed. Also, the
oil should be changed at the
intervals specified with the proper
quality and viscosity of oil. If your
engine should run excessively low
on oil or if the oil has lost its
lubricating qualities because of old
age, serious engine damage could
occur.

instrument panel at the same time
as vacuum warning buzzer sound,
and check that the brake low
vacuum warning light comes on.
3. Then, after you start the engine,
the main vacuum pump driven by
the engine will start running. If the
electric vacuum pump operation
(noisy sound) and the vacuum
warning buzzer stop, and the brake
low vacuum warning light goes off
thereafter, the operation is normal.
4. If you cannot hear the noisy
sound of the electric vacuum pump,
check the electrical wiring and
repair as necessary. If it cannot be
repaired, replace the electric
vacuum pump.20. BRAKE FLUID :
