Exterior Care

■

Etching Caused by Acid Rain or Industrial Fallout
● Occurrence

Industrial pollutants and vehicle emissions drift into the air and
mix with rain or dew to form acids. These acids can settle on a
vehicle’s finish. As the water evaporates, the acid becomes con-
centrated and can damage the finish.

And the longer the acid remains on the surface, the greater the
chance is for damage.

● Prevention

It is necessary to wash and wax your vehicle to preserve its finish
according to the instructions in this section. These steps should
be taken immediately after you suspect that acid rain has settled
on your vehicle’s finish.

■

Damage Caused by Bird Dropping, Insects, or Tree Sap
● Occurrence

Bird droppings contain acids. If these are not removed they can
eat away the clear and color base coat of the vehicle’s paintwork.

When insects stick to the paint surface and decompose, corro-
sive compounds form.

These can erode the clear and color base coat of the vehicle’s
paintwork if they are not removed.

Tree sap will harden and adhere permanently to the paint finish.
If you scratch the sap off while it is hard, some vehicle paint could
come off with it.

The paintwork on your Scion represents the latest technical
developments in composition and methods of application.

Environmental hazards, however, can harm the paint’s protec-
tive properties, if proper care is not taken.

Here are some examples of possible damage, with tips on how
to prevent them.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

● Prevention

It is necessary to have your Scion washed and waxed to pre-
serve its finish according to the instructions in this section. This
should be done as soon as possible.

Bird droppings can be removed with a soft sponge and water. If
you are traveling and these are not available, a moistened tissue
may also take care of the problem. The cleaned area should be
waxed according to the instructions in this section.

Insects and tree sap are best removed with a soft sponge and
water or a commercially available chemical cleaner.

Another method is to cover the affected area with dampened
newspaper for one to two hours. After removing the newspaper,
rinse off the loosened debris with water.

■

Water Marks
● Occurrence

Rain, fog, dew, and even tap water can contain harmful minerals
such as salt and lime. If moisture containing these minerals set-
tles on the vehicle and evaporates, the minerals will concentrate
and harden to form white rings. The rings can damage your vehi-
cle’s finish.

● Prevention

It is necessary to wash and wax your vehicle to preserve its finish
according to the instructions in this section. These steps should
be taken immediately after you find water marks on your vehi-
cle’s finish.

■

Paint Chipping
● Occurrence

Paint chipping occurs when gravel thrown in the air by another
vehicle’s tires hits your vehicle.

● How to avoid paint chipping

Keeping a safe distance between you and the vehicle ahead
reduces the chances of having your paint chipped by flying
gravel.

Follow all label and container directions when using a chemical
cleaner or polish. Read all warnings and cautions.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

470

iA_OM_OM99M17z_(U)

●

The paint chipping zone varies with the speed of the vehicle. For example,
when traveling at 56 mph (90 km/h), the paint chipping zone is 164 ft.
(50 m).

●

In low temperatures a vehicle’s finish hardens. This increases the chance of
paint chipping.

●

Chipped paint can lead to rust forming on your Scion. Before this happens,
repair the damage by using Scion touch-up paint according to the instruc-
tions in this section. Failure to repair the affected area could lead to serious
rusting and expensive repairs.

■

Washing

To help protect the finish from rust and deterioration, wash your Scion
thoroughly and frequently, at least once a month, with lukewarm or
cold water.

If the vehicle is washed improperly, the paint surface could be
scratched. Here are some examples of how scratching could occur.



Scratches occur on the paint surface when

● The vehicle is washed without first rinsing off dirt and other foreign

matter.

● The vehicle is washed with a rough, dry, or dirty cloth.
● The vehicle is washed at a car wash that uses brushes that are

dirty or too stiff.

● Cleansers or wax containing abrasives are used.



To minimize scratches on the vehicle’s paint finish

● Rinse off any dirt or other foreign matter using lukewarm or cold

water before washing.

● Use plenty of lukewarm or cold water and a soft cloth when wash-

ing the vehicle. Do not use a nylon cloth.

● Rub gently when washing or drying the vehicle.
● Take your vehicle only to a car wash that keeps its brushes well

maintained.

Maintaining the Finish

-------------------------------------------------------------------------------------------------------------------------------------------------------------

iA_OM_OM99M17z_(U)

Mainten

● Do not use abrasive cleansers or wax that contain abrasives.
Pay special attention to removing salt, dirt, mud, and other foreign
material from the underside of the fenders, and make sure the drain
holes in the lower edges of the doors and rocker panels are clean.

Insects, tar, tree sap, bird droppings, industrial fallout, and similar
deposits can damage the finish if not removed immediately. When
prompt washing with plain water is ineffective, use a mild soap made
for use on vehicles.

Thoroughly rinse off all soap with lukewarm or cold water. Do not
allow soap to dry on the finish.

After washing the vehicle, dry it with a clean chamois to prevent water
spots from forming.
● When using an automatic car wash

• Retract the door mirrors.
• The automatic car wash brushes could reduce the paint luster or

hasten paint deterioration.

● When using a high water pressure car wash

High water temperature and high water pressure car washers are
available depending on the type of car wash machine. If the car
washer nozzle is put too close to the vehicle, the force of the spray
could damage or deform the molding, affect the sealability of parts,
and allow water to penetrate the interior. Keep a sufficient space
(12 in. (300 mm) or more) between the nozzle and the vehicle. In
addition, do not spend too much time spraying the same area of the
vehicle, and be very careful when spraying between gaps in doors
and around windows.

■

Waxing

Your vehicle needs to be waxed when water no longer beads on the
finish. Always wash and dry the vehicle before waxing it. In addition
to the vehicle body, wax the metal trim to maintain its luster.

Use wax which contains no abrasives. Waxes containing abra-
sive will remove paint and could damage bright metal parts.

Use a good grade of natural wax for metallic, mica, and solid col-
ors.

When waxing, coat evenly with the sponge supplied or a soft
cloth.

Wipe off the wax with a soft cloth.

■

Maintaining the Finish

●

Scion is not responsible for scratches caused by automatic car washes or
improper washing.

●

Scratches are more noticeable on vehicles with darker paint finishes.

●

A spot remover to remove oil, tar, and similar materials will usually also take
off the wax. Rewax these areas even if the rest of the vehicle does not need
it.

WARNING

■

Dry off brakes that have become wet by driving slowly, releasing the
accelerator pedal and lightly applying the brakes several times until
the brake performance returns to normal
Driving with wet brakes is dangerous. Increased stopping distance or the
vehicle pulling to one side when braking could result in a serious accident.
Light braking will indicate whether the brakes have been affected.

NOTICE

●

Do not spray water in the engine compartment. Otherwise, it could result in
engine-starting problems or damage to electrical parts.

●

When washing and waxing the vehicle, be careful not to apply excessive
force to any single area of the vehicle.

●

Do not use steel wool, abrasive cleaners, or strong detergents containing
highly alkaline or caustic agents on chrome- plated or anodized aluminum
parts. This may damage the protective coating; also, cleaners and deter-
gents may discolor or deteriorate the paint.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

Deep scratches or chips on the finish should be repaired promptly.
Exposed metal quickly rusts and can lead to major repairs.

● Use tar remover to remove road tar and insects. Never do this with

a knife or similar tool.

● To prevent corrosion on bright- metal surfaces, apply wax or

chrome preservative and rub it to a high luster.

● During cold weather or in coastal areas, cover bright-metal parts

with a coating of wax or preservative heavier than usual. It would
also help to coat them with noncorrosive petroleum jelly or some
other protective compound.

Repairing Damage to the Finish

NOTICE

If your Scion is damaged and needs metal parts repaired or replaced, make
sure the body shop applies anti- corrosion materials to all parts, both
repaired and new. This will prevent them from rusting.

Bright-Metal Maintenance

NOTICE

Do not use steel wool, abrasive cleaners, or strong detergents containing
highly alkaline or caustic agents on chrome-plated or anodized aluminum
parts. This may result in damage to the protective coating and cause discol-
oration or paint deterioration.

Road chemicals and salt used for ice and snow removal and solvents
used for dust control may collect on the underbody. If not removed,
they will speed up rusting and deterioration of such underbody parts
as fuel lines, frame, floor pan, and exhaust system, even though these
parts may be coated with anti-corrosive material.

Thoroughly flush the underbody and wheel housings with lukewarm or
cold water at the end of each winter. Try also to do this every month.

Pay special attention to these areas because they easily hide mud
and dirt. It will do more harm than good to wet down the road grime
without removing it.

The lower edges of doors, rocker panels, and frame members have
drain holes that should not be clogged. Water trapped there will cause
rusting.

A protective coating is provided over the aluminum wheels. Special
care is needed to protect this coating.

●

Do not use a wire brush or any abrasive cleaner, polishing compound, or
solvent on aluminum wheels. They may damage the coating.

●

Always use a sponge or soft cloth to clean the wheels.
Rinse the wheels thoroughly with lukewarm or cold water. Also, be sure to
clean the wheels after driving on dusty or salted roads to help prevent corro-
sion.

●

Avoid washing your vehicle in an automatic car wash that uses high- speed
or hard brushes.

● When cleaning the plastic lenses of the lights, do not use gasoline,

kerosene, rectified spirit, paint, thinner, highly acidic detergents, or
strongly alkaline detergents. Otherwise, these chemical agents can
discolor or damage the surfaces resulting in a significant loss in
functionality. If plastic parts become inadvertently exposed to any of
these chemical agents, flush with water immediately.

● If plastic parts such as the bumpers become inadvertently exposed

to chemical agents or fluids such as gasoline, oil, engine coolant, or
battery fluid, it could cause discoloration, staining, or paint peeling.
Wipe off any such chemical agents or fluids using a soft cloth imme-
diately.

● High water temperature and high water pressure car washers are

available depending on the type of high pressure car washer
device. If the car washer nozzle is put too close to the vehicle or
aimed at one area for an extended period of time, it could deform
plastic parts or damage the paint.

● Do not use wax containing compounds (polish). Otherwise, it could

result in paint damage.

● In addition, do not use an electrical or air tool to apply wax. Other-

wise, the frictional heat generated could result in deformation of
plastic parts or paint damage.

NOTICE

Do not use any detergent other than mild detergent. Before using any deter-
gent, verify the ingredients.

Otherwise, the product could discolor or stain the aluminum wheels.

Vinyl

Remove dust and loose dirt from vinyl with a whisk broom or vac-
uum cleaner. Clean vinyl with a leather-and-vinyl cleaner.

■

Leather (if equipped)

Remove dust and sand first using a vacuum cleaner or other
means, then wipe dirt off using a soft cloth with a leather cleaner or
a soft cloth soaked in mild soap. Wipe off the remaining cleaner or
soap using a cloth soaked in clean water and wrung out well.

Remove moisture with a dry, soft cloth and allow the leather to fur-
ther dry in a well-ventilated, shaded area. If the leather gets wet
such as from rain, also remove moisture and dry it as soon as pos-
sible.

■

Fabric

Remove dust and loose dirt from fabric with a whisk broom or vac-
uum cleaner. Clean it with a mild soap solution good for upholstery
and carpets. Remove fresh spots immediately with a fabric spot
cleaner.

To keep the fabric looking clean and fresh, take care of it. Other-
wise its color will be affected, it can be stained easily, and its fire-
resistance may be reduced.

■

Panel

When the interior panels need to be cleaned, use soft material such
as a soft cloth soaked in clean water and wrung out well and lightly
wipe off dirt from the surface. If a panel requires further cleaning,
use the following procedure.

Wipe dirt off using a soft cloth soaked in mild detergent (about
5% solution).

Wipe off any remaining detergent using a cloth soaked in clean
water and wrung out well.
