Toyota, through the diligent research, de-
sign and use of the most advanced
technology available, helps prevent corro-
sion and provides you with the finest qual-
ity 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 corrosion
to your vehicle are:

The accumulation of road salt, dirt and
moisture in hard±to±reach areas under
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 environmental condi-
tions:

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 es-
pecially when temperatures range just
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 ambient temperatures can cause
corrosion to those components of the
vehicle 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:

If 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.

High 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.

Wash the underside of the vehicle thor-
oughly when winter is over.
See ªWashing and waxing your Toyotaº on
page 405 in this Section 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.
Protecting your Toyota from
corrosion

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.
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 Toyota dealer will be
happy to assist 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.
The following cases may cause weakness
to the paint or corrosion to the body and
parts. Wash your vehicle as soon as pos-
sible.

When driving in a coastal area

When driving on a road sprinkled with
antifreeze

When exposed to coal tar, tree sap,
bird droppings and carcass of an insect

When driving in areas where there is
a lot of smoke, soot, dust, iron dust or
chemical substances

When the vehicle becomes remarkably
dirty with dust and mud
Hand±washing your Toyota
Work in the shade and wait until the
vehicle body is not hot to the touch.
CAUTION
When cleaning under floor or chassis,
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 hardÐlet
the soap and water remove the dirt.
Fuel filler door: Do not apply water (high±
pressure car wash, for example) at or
near the fuel tank inlet with the fuel filler
door opened. If the water enters the air
vent, you may experience trouble with re-
fueling or rough engine idling.
Plastic wheel ornaments: The plastic
wheel ornaments are damaged easily by
organic substances. If any organic sub-
stances splashes an ornament, be sure to
wash it off with water and check if the
ornament is damaged.
CAUTION
Do not attach the heavily damaged
plastic wheel ornament. It may fly off
the wheel and cause accidents while
the vehicle is moving.

Aluminum wheels: Use only a mild soap
or neutral detergent.
Plastic bumpers: Wash carefully. Do not
scrub with abrasive cleaners. The bumper
faces are soft.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.
NOTICE
Do not use organic substances (gaso-
line, kerosene, benzine or strong sol-
vents), which may be toxic or cause
damage.
3. Rinse thoroughlyÐdried 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 hardÐyou might scratch
the paint.Automatic car wash
Your vehicle may be washed in an auto-
matic car wash, but remember that the
paint can be scratched by some types of
brushes, unfiltered washing water, or the
washing process itself. Scratching reduces
paint durability and gloss, especially on
darker colors. The manager of the car
wash should be able to advise you wheth-
er the process is safe for the paint on
your vehicle.
Waxing your Toyota
Polishing and waxing is recommended
to maintain the original beauty of your
Toyota's finish.
Apply wax once a month or if the vehicle
surface does not repel water well.
1. Always wash and dry the vehicle be-
fore you begin waxing, even if you are
using a combined cleaner and wax.
2. Use a good quality polish and wax. If
the finish has become extremely weath-
ered, use a car±cleaning polish, fol-
lowed by a separate wax. Carefully fol-
low the manufacturer 's instructions and
precautions. Be sure to polish and wax
the chrome trim as well as the paint.3. Wax the vehicle again when water
does not bead but remains on the sur-
face in large patches.
NOTICE
Always remove the plastic bumpers if
your vehicle is re±painted and placed
in a high heat paint waxing booth.
High temperatures could damage the
bumpers.

5. After completing the tire inflation
pressure measurement and ad-
justment, apply soapy water to the
valve and check for leakage.
6. Install the tire valve cap.
If a gauge and air pump are not avail-
able, have your vehicle checked by
your Toyota dealer.
CAUTION
Be sure to reinstall the tire valve
caps. Without the valve caps, dirt
or moisture could get into the
valve core and cause air leakage.
If the caps have been lost, have
new ones put on as soon as pos-
sible.
Incorrect tire inflation pressure may
waste fuel, reduce the comfort of driv-
ing, reduce tire life and make your ve-
hicle less safe to drive.
If a tire frequently needs refilling,
have it checked by your Toyota deal-
er.
CAUTION
Keep your tires properly inflated.
Otherwise, the following condi-
tions may occur and cause an ac-
cident resulting in death or seri-
ous injuries.
Low tire pressure (underinfla-
tion)Ð

Excessive wear

Uneven wear

Poor handling

Possibility of blowouts from an
overheated tire

Poor sealing of the tire bead

Wheel deformation and/or tire
separation

A greater possibility of tire
damage from road hazards
High tire pressure (overinfla-
tion)Ð

Poor handling

Excessive wear

REPLACING YOUR TIRES
When replacing a tire, use a tire of
the same size and construction,
and the same or greater maximum
load as the originally installed
tires. Also, on four±wheel drive
models, all the tires must be the
same brand and have the same
tread patterns.
Using any other size or type of tire
may seriously affect handling, ride,
speedometer/odometer calibration,
ground clearance, and clearance be-
tween the body and tires or snow
chains.
Check that the maximum load of the
replaced tire is greater than 1/2 of the
Gross Axle Weight Ratings (GAWR)
of either the front axle or the rear
axle, whichever is greater. As for the
maximum load of the tire, see the load
limit at maximum cold tire inflation
pressure mentioned on the sidewall
of the tire, and as for the Gross Axle
Weight Ratings (GAWR), see the Cer-
tification Label.For details about the side wall of the
tire and the Certification Label, see
pages 347 and 345.
CAUTION
Observe the following instruc-
tions. Otherwise, an accident
may occur resulting in death or
serious injuries.

Do not mix radial, bias belted,
or bias±ply tires on your ve-
hicle, as this may cause dan-
gerous handling characteris-
tics resulting in loss of control.

Do not use tires other than the
manufacturer's recommended
size, as this may cause danger-
ous handling characteristics
resulting in loss of control.

Four±wheel drive models:
Do not use tires of different
brands, sizes, construction or
tread patterns, as this may
cause dangerous handling
characteristics resulting in
loss of control.
For vehicles with vehicle stability
control systemÐ

Do not use tires of different
brands, sizes and construc-
tions. This may damage the
drive system and prevent the
vehicle skid control system
from functioning correctly.
