D If electrolyte gets on your skin,

thoroughly wash the contact area. If

you feel pain or burning, get medi-

cal attention immediately.

CAUTION

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.

The electrolyte contains poisonous

and corrosive sulfuric acid.

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.

Check the battery for corroded or loose

terminal connections, cracks, or loose

D Keep children away from the bat-

tery.

EMERGENCY MEASURES

b. If the terminal connections are loose,

tighten their clamp nuts—but do not

overtighten.

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-

cal office.

c. Tighten the hold−down clamp only

enough to keep the battery firmly in

place. Overtightening may damage the

battery case.

where there is not sufficient ventila-

tion.

Check the battery condition by the indi-

Checking and replacing fuses

Type A fuses can be pulled out by the

pull−out tool. The location of the pull−out

tool is shown in the illustration.

Type A

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

Type B

Blown

If you do not have a spare fuse, in an

emergency you can pull out the “A/C” or

“P/POINT”

fuse,

which

be

components do not work, check the

they must be replaced.

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

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 217 in Sec-

tion 7−1 for locations of the fuses.

Good

Type C

Blown

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 255 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

Replacing light bulbs—

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.

If any washer does not work or low

windshield washer fluid level warning

light* comes on, the washer tank may

be empty. Add washer fluid.

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.

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.

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.

D To prevent burning yourself, do not

replace the light bulbs while they

are hot.

D 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

Do not use engine antifreeze or any

other substitute because it may dam-

age your vehicle’s paint.

*: When equipped

NOTICE

Only use a bulb of the listed type.
