246CORROSION PREVENTION AND APPEARANCE CARE
Toyota, through diligent research, design
and use of the most advanced technology
available, helps prevent corrosion and pro-
vides 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 vehicle
corrosion are:
DThe accumulation of road salt, dirt and
moisture in hard−to−reach areas under
the vehicle.
DChipping of paint, or undercoating
caused by minor accidents or stones
and gravel.
Care is especially important if you live
in particular areas or operate your ve-
hicle under certain environmental condi-
tions:
DRoad 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.
DHigh humidity accelerates corrosion es-
pecially when temperatures range just
above freezing point.
DWetness 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.
DHigh ambient temperatures could cause
corrosion to those vehicle components
which do not dry quickly, 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 dam-
age 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 be
observed:
DIf you drive on salted roads in the
winter or if you live near the ocean,
you should hose off the undercarriage
at least once a month to minimize cor-
rosion.
DHigh pressure water or steam is effec-
tive for cleaning the vehicle’s underside
and wheel housings. Pay particular
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 removing. The
lower edge of doors, rocker panels and
frame members have drain holes which
should not be allowed to clog with dirt
as trapped water in these areas can
cause corrosion.
DWash the underside of the vehicle thor-
oughly when winter is over.
See “Washing and waxing your Toyota” on
page 247 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. Oc-
casionally check under the mats to make
sure the area is dry. Be particularly care-
ful when transporting chemicals, cleans-
ers, fertilizers, salt, etc.; these should be
transported in proper containers. If a spill
or leak should occur, immediately clean
and dry the area.

Protecting your Toyota from
corrosion

CORROSION PREVENTION AND APPEARANCE CARE247
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 recommend
that the fittings and the area where the
shields are installed be treated to resist
corrosion. Your authorized Toyota dealer
or repairer, or another duly qualified and
equipped professional will be happy to as-
sist in supplying and installing the shields
if they are recommended for your area.
Keep your vehicle in a well ventilated
garage or a roofed place. Do not park
your vehicle in a damp, poorly venti-
lated garage.If you wash your vehicle in
the garage, or if you drive it covered with
water or snow, your garage may be so
damp as to cause corrosion. Even if your
garage is heated, a wet vehicle can cor-
rode if the ventilation is poor.Washing your Toyota
Keep your vehicle clean by regular
washing.
NOTICE
The following cases may cause weak-
ness to the paint or corrosion to the
body and components. (aluminum
wheels etc.) Wash your vehicle as
soon as possible.
zAfter driving near the sea coast
zAfter driving on salted roads
zIf you see coal tar or tree sap on
the paint surface
zIf you see dead insects, insect
droppings or bird droppings on the
paint
zAfter driving in an area contami-
nated with soot, oily smoke, mine
dust, iron powder or chemical sub-
stances
zIf the vehicle becomes heavily
soiled in dust or mud
zIf liquids such as benzene and gas-
oline are spilled on the paint sur-
face
If the paint is chipped or scratched,
have it repaired immediately.
To prevent the wheels from corroding,
remove any dirt and store in a place
with low humidity when storing the
wheels.

Hand−washing your Toyota
Work in the shade and wait until the
vehicle body is not warm to the touch.
CAUTION
DWhen cleaning under floor or chas-
sis, be careful not to injure your
hands.
DExhaust gasses cause the exhaust
pipe to become quite hot. When
washing the vehicle, be careful not
to touch the pipe until it has cooled
sufficiently, as touching a hot ex-
haust pipe can cause burns.
1. Rinse off loose dirt with a hose. Re-
move any mud or road salt from the
underside of the vehicle or 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.
Plastic wheel ornaments: The plastic
wheel ornaments are damaged easily by
organic substances. If any organic sub-
stance splash an ornament, be sure to
wash them off with water and check if the
ornament is damaged.
Aluminum wheels: Remove any dirt imme-
diately by using a neutral detergent.
Do not use hard brushes or abrasive
cleaners. Do not use strong or harsh
chemical cleaners. Use the same mild de-
tergent and wax as used on the paint.
Do not use detergent on the wheels when
they are hot, for example after driving for
long distance in the hot weather.
Wash detergent from the wheels immedi-
ately after use.
NOTICE
zDo not use corrosive chemical−
based cleaners on your wheels. (Ex-
ample: hydrofluoric acid)
zDo not use steam cleaners or the
chemicals therein to clean your
wheels.
zDo not use scouring pads, wire
brushes, or coarse abrasives to
clean your wheels.
Plastic bumpers: Wash carefully. Do not
scrub with abrasive cleaners. The bumper
faces are soft.
Exterior lights: Wash carefully. Do not use
organic substances or scrub them with a
hard brush. This may damage the sur-
faces of the lights.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.
3. Rinse thoroughly—dried soap can
cause streaking. In hot weather you
may need to rinse each Section right
after you wash it.
4. To prevent water spots, dry the vehicle
using a clean soft cotton towel. Do not
rub or press hard—you might scratch
the paint.
NOTICE
zDo not use organic substances
(gasoline, kerosene, benzine or
strong solvents), which may be tox-
ic or cause damage.
zDo not scrub any part of the ve-
hicle with a hard brush, which may
cause damage.

properly in the floor jack point.
Raising the vehicle with the floor
jack improperly positioned will dam-
age the vehicle or may allow the
vehicle to fall off the floor jack and
cause personal injury.
DNever get under the vehicle when
the vehicle is supported by the
floor jack alone; use vehicle sup-
port stands.
DDo not raise the vehicle with any-
one in the vehicle.

Treadwear indicator
CHECKING YOUR TIRES
Check the tire’s tread for treadwear in-
dicators. If the indicators show, replace
the tires. The location of treadwear in-
dicators is shown by the “TWI” or “∆”
marks, etc., molded on the sidewall of
each tire.
The tires on your Toyota have built−in
treadwear indicators to help you know
when the tires need replacement. When
the tread depth wears to1.6 mm (0.06
in.) or less, the indicators will appear. If
you can see the indicators in two or more
adjacent grooves, the tire should be re-
placed. The lower the tread, the higher
the risk of skidding.

DO−IT−YOURSELF MAINTENANCE: Engine and Chassis271
NOTICE
Tires may have damage to its tire
wheel when receiving impact from the
road surface. Therefore, pay attention
to the following.
zBe sure to use with proper tire
inflation pressure. If the tire infla-
tion pressure is low, the tire may
have greater damage. For detailed
information about tire inflation pres-
sure, see page 299.
zAvoid driving onto high, sharp−
edged objects and other road haz-
ards. Failure to do so can lead to
severe tire damage.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16in.).
If you have tire damage such as cuts,
splits, cracks deep enough to expose
the fabric, or bulges indicating internal
damage, the tire should be replaced.
If a tire often goes flat or cannot be prop-
erly repaired due to the size or location
of a cut or other damage, it should be
replaced. If you are not sure, consult with
any authorized Toyota dealer or repairer,
or another duly qualified and equipped
professional.
If air loss occurs while driving, do not
continue driving. Driving even a short dis-
tance could damage a tire beyond repair.
Any tires which are over 6 years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the spare tire and
tires stored for future use.REPLACING YOUR TIRES
When replacing a tire, use a tire of the
same size and construction, and the
same or greater load capacity as the
originally installed tires.
Using any other size or type of tire may
seriously affect handling, ride, speedome-
ter/odometer calibration, ground clearance,
and clearance between the body and tires
or snow chains.
CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
DDo not mix radial, bias belted, or
bias−ply tires on your vehicle, as
this may cause dangerous handling
characteristics resulting in loss of
control.
DDo not use tires other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
DDo not mix tires of different makes,
models or tread patterns, and do
not mix tires of remarkably different
treadwear. This may cause danger-
ous handling characteristics result-
ing in loss of control.
Never use second−hand tires on your
To y o t a .
Using tires whose previous history is un-
known is a risk.
Toyota recommends all tires be re-
placed at a time as a set.
See “If you have a flat tire” on page 226
in Section 4 for tire change procedure.
AYGO WE 99E37E1102.18

272DO−IT−YOURSELF MAINTENANCE: Engine and Chassis
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
handling and tire life. Wheels can get out
of balance with regular use and should
therefore be balanced occasionally.
When replacing a tubeless tire, the air
valve should also be replaced with a
new one.
Rotating tires
MS72005
Steel wheels
MS72003
Aluminum wheels
To equalize tire wear and help extend
tire life, Toyota recommends that you
rotate your tires approximately every
10000 km (6000 miles). However, the
most appropriate timing for tire rotation
may vary according to your driving hab-
its and road surface conditions.
See “If you have a flat tire” on page 226
in Section 4 for tire change procedure.
When rotating tires, check for uneven
wear and damage. Abnormal wear is usu-
ally caused by incorrect tire pressure, im-
proper wheel alignment, out−of−balance
wheels, or severe braking.
