BATTERY PRECAUTIONS

The battery produces flammable and

explosive hydrogen gas.

D 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.

D Do not cause a spark from the bat-

tery with tools.

D Do not smoke or light a match near

the battery.

The electrolyte contains poisonous

and corrosive sulfuric acid.

Hold−down clamp

D 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.

D Avoid contact with eyes, skin or

clothes.

Before checking the battery, remove the

battery cover. (See “(c) Jump starting”

on page 185 in Section 4.)

D Never ingest electrolyte.

D Wear protective safety glasses when

working near the battery.

Check the battery for corroded or loose

terminal connections, cracks, or loose

hold−down clamp.

D Warning: Battery posts, terminals

and related accessories contain lead

and lead compounds, chemicals

known to the State of California to

D Keep children away from the bat-

tery.

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.

EMERGENCY MEASURES

and reproductive

harm. Wash hands after handling.

D 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-

enough to keep the battery firmly in

place. Overtightening may damage the

battery case.

CHECKING BY INDICATOR

D 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.

Check the battery condition by the indi-

cator color.

Checking and replacing fuses

Type A fuses can be pulled out by using

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.

Good

Blown

If you do not have a spare fuse, in an

emergency you can pull out the “RADIO”

or “A/C” fuse, which may be dispensable

for normal driving, and use it if its amper-

age rating is the same.

Type A

If the headlights or other electrical

components do not work, check the

fuses. If any of the fuses are blown,

they must be replaced.

If you cannot use one of the same amper-

age, use one that is lower, but as close

as possible to the rating. 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.

See “Fuse locations” on page 219 in Sec-

tion 7−1 for locations of the fuses.

Turn the ignition switch and inoperative

component off. Pull a 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 258 in Section 8 of this manual for

the functions controlled by each circuit.

It is a good idea to purchase a set of

spare fuses and keep them in your ve-

hicle for emergencies.

Adding washer fluid

If the new fuse immediately blows out,

there is a problem with the electrical sys-

tem. Have your Toyota dealer correct it as

soon as possible.

NOTICE

Do not use engine antifreeze or any

other substitute because it may dam-

age your vehicle’s paint.

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.

If any washer does not work, the wash-

er tank may be empty. Check the wash-

er fluid level on the level gauge. If the

washer fluid level is below “LOW”, add

washer fluid.

You may use plain water as washer fluid.

However, in cold areas where tempera-

tures range below freezing point, use

washer fluid containing antifreeze. This

product is available at your Toyota dealer

and most auto parts stores. Follow the

manufacturer’s directions for how much to

mix with water.

Replacing light bulbs—

The following illustrations show how to

gain access to the bulbs. When replacing

a bulb, make sure the ignition switch and

light switch are off. Use bulbs with the

wattage ratings given in the table.

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 fogged 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

Toyota dealer.
