CAUTION
Observe the following instructions.
Otherwise, an accident may occur re-
sulting in death or serious injuries.
DDo not use wheels other than the
manufacturer ’s recommended size,
as this may cause dangerous han-
dling characteristics resulting in
loss of control.
DWhen installing the wheel nuts, be
sure to install them with the ta-
pered ends facing inward. See
“—Installing wheel” on page 159 in
Section 4.

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. Get emergency medical
attention immediately.
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.)

Ground
cable
Hold−down
clamp
On some models, before checking the
battery, remove the battery cover.
Check the battery for corroded or loose
terminal connections, cracks, or 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.

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. (See “ADDING
DISTILLED WATER” on page 202.)

Low O.K.
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
directly above the cell as illustrated
above.
3. Retighten the vent plugs securely.
NOTICE
Do not overfill the cells. Excess elec-
trolyte could squirt out of the battery
during heavy charging, causing corro-
sion or damage.
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 bat-
tery in a garage or closed room
where there is not sufficient ventila-
tion.
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 182 in Sec-
tion 7−1 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 219 in Section 8 for the functions
controlled by each circuit.
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”,
“DOME” or “A/C” fuse, which may be dis-
pensable for normal driving, and use it if
its amperage rating is the same.

Checking and replacing fuses

204DO−IT−YOURSELF MAINTENANCE: Electrical components
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 a new fuse immediately blows out, there
is a problem with the electrical system.
Have any authorized Toyota dealer or re-
pairer, 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.
If washer fluid does not come out, the
washer fluid tank may be empty. To
check the washer fluid level, simply
look at the transparent tank. If the level
is low, 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.

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
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 any
authorized Toyota dealer or repairer, or
another duly qualified and equipped
professional.Light bulbs
