To check the fluid level, simply look at
the seethrough reservoir. The level
should be between the “MAX” and
“MIN” lines on the reservoir.
It is normal for the brake fluid level to go
down slightly as the brake pads wear. So
be sure to keep the reservoir filled.
If the reservoir needs frequent refilling, it
may indicate a serious mechanical prob-
lem. If the level is low, add SAE J1703 or
FMVSS No.116 DOT 3 brake fluid to the
brake reservoir.
Remove and replace the reservoir cap by
hand. Fill the brake fluid to the dotted
line. This brings the fluid to the correct
level when you put the cap back on.
Use only newly opened brake fluid. Once
opened, brake fluid absorbs moisture from
the air, and excess moisture can cause a
dangerous loss of braking.
CAUTION
Take care when filling the r
eservoir
because brake fluid can harm your
eyes and damage painted surfaces. If
fluid gets in your eyes, flush your
eyes with clean water immediately. If
you still feel uncomfortable with your
eyes, go to the doctor.
NOTICE
If you spill some of the fluid, be sure
to wash it off with water to prevent
it from damaging the parts or paint.

Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRON
 II or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (60 C—80 C or 140 F—175 F). You
may also check the level when the fluid
is cold (about room temperature,
10 C—30 C or 50 F—85 F) if the engine
has not been run for about five hours.

NOTICE
Do not attempt to use a tire chain on
the compact spare tire, as it may re-
sult in damage to the vehicle as well
as the tire.
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion, the
wheel should be replaced.
If you fail to replace damaged wheels, the
tire may slip off the wheel or cause loss
of handling control.
WHEEL SELECTION
When replacing wheels, care should be
taken to ensure that the wheels are re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
This must be observed on compact spare
tire, too.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ability, headlight
aim, bumper height, vehicle ground clear-
ance, and tire or snow chain clearance to
the body and chassis. Replacement with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened may
have structural damage and therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.

CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and
explosive hydrogen gas.
Do not cause a spark from the bat-
tery with tools.
Do not smoke or light a match near
the battery.
The electrolyte contains poisonous
and corrosive sulfuric acid.
Avoid contact with eyes, skin or
clothes.
Never ingest electrolyte.
Wear protective safety glasses when
working near the battery.
Keep children away from the bat-
tery.
EMERGENCY MEASURES
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.
If electrolyte gets on your skin,
thoroughly wash the contact area. If
you feel pain or burning, get medi-
cal attention immediately.
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.
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.
Warning: Battery posts, terminals
and related accessories contain lead
and lead compounds, chemicals
known to the State of California to
cause cancer and reproductive
harm. Wash hands after handling.

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 holddown clamp only enough to keep the battery firmly in
place. Overtightening may damage the
battery case.

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 203 in Sec-
tion 71 for locations of the fuses.
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 237 in Section 8 of this manual for
the functions controlled by each circuit. Type A fuses can be pulled out by the
pullout tool. The location of the pullout
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 “A/C” or
“P/POINT” fuse, which may be
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.
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 your Toyota dealer 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 any washer does not work or low
windshield washer fluid level warning
light* comes on, the washer tank may
be empty. Add washer fluid.
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.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
*: When equippedThe 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.
CAUTION
To prevent from burning yourself,
do not replace the light bulbs while
they are hot.
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
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 fogged 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 your
Toyota dealer.Light bulbsBulb
