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.
