If you perform maintenance by your-
self, be sure to follow the correct pro-
cedure given in this part.
You should be aware that improper or in-
complete servicing may result in operat-
ing problems.
Performing do-it-yourself maintenance
during the warranty period may affect
your warranty coverage. Read the sepa-
rate Toyota Warranty statement for details
and suggestions.
This part gives instructions only for those
items that are relatively easy for an owner
to perform. As explained in Part 6, there
are still a number of items that must be
done by a qualified technician with special
tools.
For information on tools and parts for do-
it-yourself maintenance, see Parts and
toolsº.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:

When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)

Right after driving, the engine
compartmentÐthe engine, radia-
tor, exhaust manifold, power
steering fluid reservoir and spark
plug boots, etc.Ðwill be hot. So
be careful not to touch them. Oil,
fluids and spark plugs may also be
hot.

If the engine is hot, do not remove
the radiator cap or loosen the
drain plugs to prevent burning
yourself.

Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flam-
mable.

Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric
acid.

Do not get under your vehicle with
just the body jack supporting it.
Always use automotive jack
stands or other solid supports. CAUTION

Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling
fans will automatically start to run
if the engine coolant temperature
is high and/or the air conditioning
is on.

Use eye protection whenever you
work on or under you vehicle
where you may be exposed to fly-
ing or falling material, fluid spray,
etc.

Used engine oil contains poten-
tially harmful contaminants which
may cause skin disorders such as
inflammation or skin cancer, so
care should be taken to avoid pro-
longed and repeated contact with
it. To remove used engine oil from
your skin, wash thoroughly with
soap and water.

Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers
or onto the ground. Call your deal-
er or a service station for informa-
tion concerning recycling or dis-
posal.

Remember that battery and igni- tion cables carry high currents or
voltages. Be careful of accidental-ly causing a short circuit.
Add only demineralized or dis-tilled w ater to fill the radiator. And
if you spill some of the coolant, be sure to wash it off with water to
prevent it from damaging theparts or paint.
Do not allow dirt or anything elseto fall through the spark plug
holes.
Do not pry the outer electrode of aspark plug against the center elec-
trode.
Use only spark plugs of the speci- fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
NOTICE
Do not reuse platinum-tipped
spark plugs by cleaning or regap-
ping.
Do not overfill automatic trans-mission fluid, or the transmission
could be damaged.
Do not drive with the air cleaner fil-ter removed, or excessive engine
wear could result. Also backfiringcould cause a fire in the enginecompartment.
Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood,check to see that you have not for-gotten any tools, rags, etc.

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.
