ÐChecking battery exterior
60170F12
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 baking
soda. Coat the outside of the terminals
with grease to prevent further corrosion.
b. If the terminal connections are loose,
tighten their clamp nutsÐbut do not over-
tighten.
c. Tighten the hold- down clamp only
enough to keep the battery firmly in place.
Overtightening may damage the battery
case.
NOTICE
Be sure the engine and all accesso- ries are off before performing main-tenance.
When checking the battery, remove
the ground cable from the negativeterminal (º±º mark) first and rein-stall it last.
Be careful not to cause a short cir- cuit with tools.
Take care no solution gets into thebattery when washing it.

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 ºFuse locationsº in Chapter 7- 1 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
Part 8 of this manual for the functions
controlled by each circuit.
Type A fuses can be pulled out by the
pull- out tool. 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 ºRAD
NO.2º, ºDOMEº or ºHTRº 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.

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 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.
Checking the headlight aim
60500F11
Before checking the headlight aim: 1. Be sure that the body around the head- light is not deformed.
2. Park the vehicle on a level spot.
3. The driver gets into the driver's seat and puts the vehicle in a state ready-
ing for a driving (with a full tank).
4. Bounce the vehicle several times.60500F02
To check the headlight aim, check the
vertical and horizontal gauges. 1. Look at the beam angle gauge (vertical movement). The bubble of the gauge
should not deviate from the center of
the gauge by more than two marks on
either side of the gauge.

60500F04
2. Look at the beam angle gauge (hori- zontal movement). The º0º mark should
not deviate by more than one mark on
either side of the gauge.
If the error is over the value specified
above, take the vehicle to your Toyota
dealer to adjust the headlight aim. Replacing light bulbsÐ
The 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
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 barehands.
NOTICE
Only use a bulb of the listed type.
