1997 TOYOTA AVALON Owners Manual

193


After driving your vehicle the first 1600
km (1000 miles), check that the wheel
nuts are tight.

If you have rotated, repaired, or
changed your tires, check that the
wheel nuts are still tight after driving
1600 km (1000 miles).

When using tire chains, be careful not
to damage the aluminum wheels.

Use only the Toyota wheels, nuts and
wrench designed for your aluminum
wheels.

When balancing your wheels, use only
Toyota balance weights or equivalent
and a plastic or rubber hammer.

As with any wheel, periodically check
your aluminum wheels for damage. If
damaged, replace immediately.

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. CAUTION
!

If electrolyte gets on your skin,
thoroughly wash the contact area.
If you feel pain or burning, get
medical attention immediately.

If electrolyte gets on your clothes,
there is a possibility of its soaking
through to your skin, so immedi-
ately take off the exposed clothing
and follow the procedure above, if
necessary.

If you happen to swallow electro-
lyte, drink a large quantity of water
or milk. Follow with milk of mag-
nesia, beaten raw egg or vegetable
oil. Then go immediately for emer-
gency help.

Check the battery for corroded or
loose terminal connections, cracks, or
loose hold-down clamp.
a. If the battery is corroded, wash it offwith 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
Be sure the engine and all acces-sories are off before performing
maintenance.
When checking the battery, re-move the ground cable from the
negative terminal (-º mark) firstand reinstall it last.
Be careful not to cause a short cir-cuit with tools.
Take care no solution gets into thebattery when washing it.
There are two types of batteries: Main-
tenance type and non-maintenance
type.
A non-maintenance battery has MAIN-
TENANCE FREE BATTERYº on its top. A
maintenance type battery does not have
such indication.
Maintenance type batteryÐ
Check the fluid condition by the fluid level
lines on the side of the battery. Or if the
battery has a hydrometer on its top, you
can also check the hydrometer.
Non-maintenance batteryÐ
Check the battery condition by the
hydrometer on the top of the battery.

CHECKING BY THE FLUID LEVEL
LINES (MAINTENANCE TYPE BAT-
TERY ONLY)
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 DIS-
TILLED WATERº.)CHECKING BY THE HYDROMETER
Check the battery condition by the
hydrometer color.

ADDING DISTILLED WATER (MAINTE-
NANCE TYPE BATTERY ONLY)
1. Remove the vent plugs.
2. Add distilled water to cells needingfluid.
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 electrolyte could squirt out of the
battery during heavy charging,causing corrosion or damage.During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. Maintenance type batteriesÐRemove the vent plugs.
2. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
3. Be sure the power switch on the re- charger is off when connecting the
charger cables to the battery and
when disconnecting them.

Always charge the battery in an
unconfined area. Do not charge
the battery in a garage or closed
room where there is not sufficient
ventilation.

Non-maintenance batteries: Only
do a slow charge (5A or less).
Charging at a quicker rate is dan-
gerous. The battery may explode,
causing personal injuries.
Maintenance type batteries: Be
sure to remove the vent plugs be-
fore recharging. CAUTION

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 locationsº in Chapter 7-1 for
locations of the fuses.
Turn the ignition switch and inopera-
tive component off. Pull a suspected
fuse straight out and check it.
Determine wh ich 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 con-
trolled by each circuit.
Checking and replacing fuses
ProCarManuals.com

200Type 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/RA-
DIO,º DOMEº or HEATERº 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 vehicle 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.
Never use a fuse with a higher
amperage rating, or any other
object, in place of a fuse. This may
cause extensive damage and
possibly a fire.
CAUTION
!
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
damage your vehicle's paint.
