CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and
explosive hydrogen gas.
DDo not cause a spark from the bat-
tery with tools.
DDo not smoke or light a match near
the battery.
The electrolyte contains poisonous
and corrosive sulfuric acid.
DAvoid contact with eyes, skin or
clothes.
DNever ingest electrolyte.
DWear protective safety glasses when
working near the battery.
DKeep children away from the bat-
tery.
EMERGENCY MEASURES
DIf 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.
DIf electrolyte gets on your skin,
thoroughly wash the contact area. If
you feel pain or burning, get medi-
cal attention immediately.
DIf 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.
DIf 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.
The electricity stored in the battery will
discharge gradually even when the vehicle
is not in use, due to natural discharge
and the draining effects of certain electri-
cal appliances. If the vehicle is left for a
long time, the battery may discharge, and
the engine may be unable to start. (The
battery recharges automatically during
driving.)
The meanings of each caution symbol
on the top of the battery are as fol-
lows:
No smoking, no naked
flames, no sparks
Shield eyes
Keep away from children
Battery acid

MS73029a
Terminals
Hold−down clamp
Check the battery for corroded or loose
terminal connections, cracks, and a
loose hold−down 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
zBe sure the engine and all accesso-
ries are off before performing main-
tenance.
zWhen checking the battery, remove
the ground cable from the negative
terminal (“−” mark) first and rein-
stall it last.
zBe careful not to cause a short cir-
cuit with tools.
zTake 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 turn the
engine switch to the “LOCK” position
and then 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
DAlways 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.
DOnly do a slow charge (5 A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.

If 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 259 in Sec-
tion 7−1for 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. See page 300 in Section 8 for
the functions controlled by each circuit.
Type A fuses can be pulled out using the
pull−out tool. The location of the pull−out
tool is shown in the illustration.
If you are not sure whether a 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.
If you do not have a spare fuse, in an
emergency you can pull out the “DOME”
fuse, which may be dispensable for nor-
mal 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 a
correct fuse as soon as possible and re-
turn 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 any authorized Toyota dealer or
repairer, or another duly qualified and
equipped professional, 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 Toyota dealer
or repairer and most auto parts stores or
another duly qualified professional. 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.
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.
CAUTION
DTo prevent burning yourself, do not
replace the light bulbs while they
are hot.
DHalogen 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 wind-
shield 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 any autho-
rized Toyota dealer or repairer, or another
duly qualified and equipped professional.
