CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and
explosive hydrogen gas.
Do not cause a spark from the bat-
tery with tools.
Do not smoke or light a match near
the battery.
The electrolyte contains poisonous
and corrosive sulfuric acid.
Avoid contact with eyes, skin or
clothes.
Never ingest electrolyte.
Wear protective safety glasses when
working near the battery.
Keep children away from the bat-
tery.
EMERGENCY MEASURES
If electrolyte gets in your eyes,
flush your eyes with clean water
immediately and get immediate
medical attention. If possible, con-
tinue to apply water with a sponge
or cloth while en route to the medi-
cal office.
If electrolyte gets on your skin,
thoroughly wash the contact area. If
you feel pain or burning, get medi-
cal attention immediately.
If electrolyte gets on your clothes,
there is a possibility of its soaking
through to your skin, so immediate-
ly take off the exposed clothing and
follow the procedure above, if nec-
essary.
If you accidentally swallow electro-
lyte, drink a large quantity of water
or milk. Follow with milk of magne-
sia, beaten raw egg or vegetable
oil. Then go immediately for emer-
gency help.
—Checking battery exterior
Hold −down clamp
TerminalsGround cable
Check the battery for corroded or loose
terminal connections, cracks, or loose
holddown clamp.
a. If the battery is corroded, wash it off with a solution of warm water and bak-
ing soda. Coat the outside of the termi-
nals with grease to prevent further cor-
rosion.
b. If the terminal connections are loose, tighten their clamp nuts—but do not
overtighten.
c. Tighten the hold −down clamp only
enough to keep the battery firmly in
place. Overtightening may damage the
battery case.

NOTICE
Be sure the engine and all accesso-
ries are off before performing main-
tenance.
 When checking the battery, remove
the ground cable from the negative
terminal (“–” mark) first and rein-
stall it last.
 Be careful not to cause a short cir-
cuit with tools.
 Take care no solution gets into the
battery when washing it.

Battery recharging precautions
During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Be sure the power switch on the re- charger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (5A or less).
Charging at a quicker rate is dan-
gerous. The battery may explode,
causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.

Checking and replacing fuses
73XB020
Ty p e A
73XB021
Ty p e B
73XB022
Ty p e CIf the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See “Fuse locations” on page 233 for
locations of the fuses.
Turn the engine switch and inoperative
component off. Pull the suspected fuse
straight out and check it.
Determine which fuse may be causing the
problem. The lid of the fuse box shows
the name of the circuit for each fuse. See
page 266 for the functions controlled by
each circuit.

255
Type C—When any of the fuses are
blown, contact your Scion dealer.
Type A fuses can be pulled out by the
pull−out tool. The location of the pull −out
tool is shown in the illustration.
If you are not sure whether the fuse has
blown, try replacing the suspected fuse
with one that you know is good.
If the fuse has blown, push a new fuse
into the clip.
Only install a fuse with the amperage rat-
ing designated on the fuse box lid.
If you do not have a spare fuse, in an
emergency you can pull out the “CIG”
fuse, which may be dispensable for
normal driving, and use it if its amperage
rating is the same.
If you cannot use one of the same amper-
age, use one that is lower, but as close
to the rating as possible. If the amperage
is lower than that specified, the fuse
might blow out again but this does not
indicate anything wrong. Be sure to get
the correct fuse as soon as possible and
return the substitute to its original clip.
It is a good idea to purchase a set of
spare fuses and keep them in your ve-
hicle for emergencies. If the new fuse immediately blows out,
there is a problem with the electrical sys-
tem. Have your Scion dealer correct it as
soon as possible.
CAUTION
Never use a fuse with a higher am-
perage rating, or any other object, in
place of a fuse. This may cause ex-
tensive damage and possibly a fire.
Adding washer fluid
If any washer does not work, the wash-
er tank may be empty. Add washer
fluid.
You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below the freezing point, use
washer fluid containing antifreeze. This
product is available at your Scion dealer
and most auto parts stores. Follow the
manufacturer ’s directions for how much to
mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.

256
Replacing light bulbs—
The following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the engine switch and
light switch are off. Use bulbs with the
wattage ratings given in the table.
The high mounted stoplight consists of a
number of LEDs. If any of the LEDs burn
out, take your vehicle to your Scion dealer
to have the light replaced.
CAUTION
To prevent burning yourself, do not
replace the light bulbs while they
are hot.
Halogen bulbs have pressurized gas
inside and require special handling.
They can burst or shatter if
scratched or dropped. Hold a bulb
only by its plastic or metal case.
Do not touch the glass part of a
bulb with bare hands.
NOTICE
Only use a bulb of the listed type.
The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lens becomes wet in the rain or
in a car wash. This is not a problem
because the fogging is caused by the
temperature difference between the outside
and inside of the lens, just like the
windshield fogs up in the rain. However, if
there is a large drop of water on the
inside of the lens, or if there is water
pooled inside the light, contact your Scion
dealer.Light bulbsBulb
