Terminals

CAUTION

BATTERY PRECAUTIONS

The battery produces flammable and ex-

plosive hydrogen gas.

D Do not cause a spark from the battery

with tools.

D Do not smoke or light a match near the

battery.

Hold--down

clamp

Ground cable

The electrolyte contains poisonous and

corrosive sulphuric acid.

D Avoid contact with eyes, skin or

clothes.

Check the battery for corroded or loose

terminal connections, cracks, or loose

hold-down clamp.

D Never ingest electrolyte.

D Wear protective safety glasses when

working near the battery.

a. If the battery is corroded, wash it off

with

a

solution of warm water and

baking soda. Coat the outside of the

terminals with grease to prevent

further corrosion.

D Keep children away from the battery.

EMERGENCY MEASURES

D If electrolyte gets in your eyes, flush

your eyes with clean water immediate-

ly and get immediate medical atten-

tion. If possible, continue to apply

water with a sponge or cloth while en

route to the medical office.

b. If the terminal connections are loose,

tighten their clamp nuts—but do not

overtighten.

c. Tighten the hold-down clamp only en-

ough to keep the battery firmly in

place. Overtightening may damage the

battery case.

D If electrolyte gets on your skin, thor-

oughly wash the contact area. If you

feel pain or burning, get medical

attention immediately.

NOTICE

D Be sure the engine and all accessories

are off before performing mainte-

nance.

D If electrolyte gets on your clothes,

there is a possibility of its soaking

through to your skin, so immediately

take off the exposed clothing and fol-

low the procedure above, if neces-

sary.

D When checking the battery, remove

the ground cable from the negative

terminal (“- ” mark) first and reinstall

it last.

D If you accidentally swallow electro-

lyte, drink a large quantity of water or

milk. Follow with milk of magnesia,

beaten raw egg or vegetable oil. Then

go immediately for emergency help.

D Be careful not to cause a short circuit

with tools.

D Take care no solution gets into the

battery when washing it.

—Checking battery fluid

NOTICE

Do not overfill the cells. Excess electro-

lyte could squirt out of the battery dur-

ing heavy charging, causing corrosion

or damage.

Upper line

Lower line

CHECKING BY FLUID LEVEL LINES

The fluid (electrolyte) level must be be-

tween the upper and lower lines.

When checking the fluid level, look at all six

cells, not just one or two.

If the level is lower than the lower line, add

distilled water.

Low

Normal

ADDING DISTILLED WATER

1. Remove the vent plugs.

2. Add distilled water to cells needing fluid.

If the side of your battery is covered,

check the water level by looking down di-

rectly above the cell as illustrated above.

3. Retighten the vent plugs securely.

Battery recharging precautions

Checking and replacing fuses

During recharging, the battery is produc-

ing 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 recharger

is off when connecting the charger cables

to the battery and when disconnecting

them.

CAUTION

Type C

D Always charge the battery in an un-

confined area.

D Do not charge the battery in a garage

or closed room where there is not suf-

ficient ventilation.

D Be sure to remove the vent plugs be-

fore recharging.

NOTICE

Never recharge the battery while the en-

gine is running. Also, be sure all acces-

sories are turned off.

If you cannot use one of the same amperage,

use one that is lower, but as close to the rat-

ing 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 pos-

sible 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 vehicle for emer-

gencies.

If the new fuse immediately blows out, there

is a problem with the electrical system. Have

your Toyota dealer correct it as soon as pos-

If the headlights or other electrical compo-

sible.

nents do not work, check the fuses. If any

of the fuses are blown, they must be re-

placed.

CAUTION

See “Fuse locations” on page 252 in Section

7--1 for locations of the fuses.

Never use a fuse with a higher amperage

rating, or any other object, in place of

a fuse. This may cause extensive dam-

age and possibly a fire.

Turn the ignition 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

284 in Section 8 for the functions controlled

by each circuit.

Type B fuses—When any of the fuses are

blown, contact your Toyota 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 rating

designated on the fuse box lid.

If you do not have a spare fuse, in an

emergency you can pull out the “RADIO

NO.1” or “PWR OUTLET” fuse, which may

be dispensable for normal driving, and use

it if its amperage rating is the same.
