Cleaning the interior
Toyota, through its diligent research, de-
sign and use of the most advanced
technology available, has done its part to
help prevent corrosion and has provided you with the finest quality vehicle
construction. Now, it is up to you. Proper
care of
your Toyota can help ensure long-
term corrosion prevention.
The most common causes of corro-
sion to your vehicle are: The accumulation of road salt, dirt and
moisture in hard-to-reach areas un- der the vehicle.
Chipping of paint, or undercoating
caused by minor accidents or by
stones and gravel.
Care is especially important if you live
in particular areas or operate your ve-
hicle under certain environmentalconditions: Road salt or dust control chemicals will
accelerate corrosion, as will the pres-
ence of salt in the air near the sea-
coast or in areas of industrial pollution.
High humidity accelerates corrosion
especially when temperatures rangejust above the freezing point.
Wetness or dampness to certain parts
of your vehicle for an extended period
of time, may cause corrosion even
though other parts of the vehicle may
be dry.
High temperatures will cause corro-
sion to those components of the ve-
hicle which are prevented from quick-
drying due to lack of proper ventilation.
The above signifies the necessity to keep
your vehicle, particularly the underside,
as clean as possible and to repair any
damage to paint or protective coatings as
soon as possible.
To help prevent corrosion on your
Toyota, follow these guidelines:
Wash your vehicle frequently. It is, of
course, necessary to keep your vehicle
clean by regular washing, but to prevent corrosion, the following points should beobserved: If you drive on salted roads in the win-
ter or if you live near the ocean, you
should hose off the undercarriage atleast once a month to minimize corro- sion.

High pressure water or steam is effec-
tive for cleaning the vehicle's under-
side and wheel housings. Pay particu-
lar attention to these areas as it is
difficult to see all the mud and dirt. It
will do more harm than good to simply
wet the mud and debris without remov-
ing them. The lower edge of doors,
rocker panels and frame members
have drain holes which should not be
allowed to clog with dirt as trapped wa-
ter in these areas can cause corrosion.
Wash the underside of the vehicle
thoroughly when winter is over.
See Washing and waxing your Toyotaº
for more tips.
Check the condition of your vehicle's
paint and trim. If you find any chips or
scratches in the paint, touch them up im- mediately to prevent corrosion from start- ing. If the chips or scratches have gone
through the bare metal, have a qualified
body shop make the repair. Check the interior of your vehicle.
Wa-
ter and dirt can accumulate under the floor
mats and could cause corrosion. Occa-
sionally check under the mats to make sure the area is dry. Be particularly careful
when transporting chemicals, cleansers,
fertilizers, salt, etc.; these should be
transported in proper containers. If a spill
or leak should occur, immediately clean
and dry the area.
Use mud shields on your wheels. If you
drive on salted or gravel roads, mud
shields help protect your vehicle. Full- size shields, which come as near to the
ground as possible, are the best. We rec-
ommend that the fittings and the area
where the shields are installed be treated
to resist corrosion. Your Toyota dealer will
be happy to assist in supplying and instal-
ling the shields if they are recommended for your area.
Do not park your vehicle in a damp, poorly ventilated garage. If you wash
your vehicle in the garage, or if you drive
it in covered with water or snow, your ga- rage may be so damp it will cause corro-
sion. Even if your garage is heated, a wet
vehicle can corrode if the ventilation is
poor. Washing your Toyota by hand
Work in the shade and wait until the ve-
hicle body is not hot to the touch.
CAUTION
When cleaning under floor or chas-
sis, be careful not to injure your hands.!
1. Rinse off loose dirt with a hose. Re- move any mud or road salt from the
underside of the vehicle or in the wheel
wells.
2. Wash with a mild car-wash soap, mixed according to the manufacturer's
instructions. Use a soft cotton mitt and
keep it wet by dipping it frequently into
the wash water. Do not rub hard-let the soap and water remove the dirt.
Aluminum wheels: Use only a mild soap or
neutral detergent.
Road tar: Remove with turpentine or
cleaners that are marked safe for paintedsurfaces.
Do not use gasoline or strong
solvents, which may be toxic or
cause damage.

Windows
The windows may be cleaned with any
household window cleaner.
When cleaning the inside of the
windows, be careful not to scratch
or damage the heater wires on therear window.
NOTICE
Air conditioning control panel, car au-
dio, instrument panel, console panel,
and switches Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or luke-
warm water then lightly wipe off any dirt.

Do not use organic substances(solvents, kerosene, alcohol, gas-
oline, etc.) or alkaline or acidicsolutions. These chemicals cancause discoloring, staining or
peeling of the surface.
NOTICE
If you use cleaners or polishingagents, make sure their ingredi-
ents do not include the sub-
stances mentioned above.
If you use a liquid car freshener,do not spill the liquid onto the ve-
hicle's interior surfaces. It maycontain the ingredients men-
tioned above. Immediately clean
any spill using the method men-tioned above.
If you have any questions about the
cleaning of your Toyota, your local To-
yota dealer will be pleased to answer them.

160Engine coolant level Make sure the coolant level is between
the FULLº and LOWº lines on the see-
through
reservoir when the engine is cold.
See Chapter 7-2 for additional informa-tion when the engine is cold. Battery electrolyte level Make sure the electrolyte level of all bat-
tery cells is between upper and lower level
lines on the case. Add only distilled water
when replenishing. See Chapter 7-3 for
additional information. Brake fluid level
Make sure the brake fluid level is correct. See Chapter 7-2 for additional informa- tion.
Engine oil level
Check the l evel on the dipstick with the en-
gine turned off and the vehicle parked on
a level spot. See Chapter 7-2 for addition-
al information. Power steering fluid level Check the level on the dipstick. The level
should be in the HOTº or COLDº range
depending on the fluid temperature. See Chapter 7-2 for additional information. Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, havethe cause located and corrected immedi-
ately. (See engine exhaust cautions in
Part 2.)
Be on the alert for changes in perfor-
mance, sounds, and visual tip-offs
that in-
dicate service is needed. Some important
clues are as follows: Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
Flat-looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving straight on a level road
Strange noises related to suspensionmovement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continual-
ly higher than normal
