Maintenance and Care
Inspect the fuse and replace
it if it is blown.Normal
Blown
Insert a new fuse of the same amperage rating, and make sure it
fits tightly. If it does not fit tightly, have an expert install it. We rec-
ommend your Scion dealer.
If you have no spare fuses, borrow one of the same rating from a
circuit not essential to vehicle operation, such as the AUDIO or
OUTLET circuit.
Reinstall the cover and make sure that it is securely installed.
■Replacing the fuses under the hood
If the headlights or other electrical components do not work and the
fuses in the cabin are normal, inspect the fuse block under the
hood. If a fuse is blown, it must be replaced. Follow these steps:
Make sure the ignition is switched off, and other switches are off.
Remove the fuse block
cover.

WARNING
■Do not replace the main fuse and multiplex slow blow fuse by yourself.
Have your Scion dealer perform the replacement
Replacing these fuses by yourself is dangerous because they are high cur-
rent fuses. Incorrect replacement could cause an electrical shock or a short
circuit resulting in a fire.
NOTICE
Always replace a fuse with a genuine Scion fuse or equivalent of the same
rating. Otherwise you may damage the electric system.

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 ev aporates, 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 sus pect 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 pain t 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 pe rmanently 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.

Maintenance and Care
●Prevention
It is necessary to have your Scion washed and waxed to pre-
serve its finish according to the in structions 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 inst ructions 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 evapor ates, the minerals will concentrate
and harden to form white rings. Th e 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.

4705-4. Appearance Care
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 improp erly, 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 wa sh 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.
