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 andtoolsº.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few pr ecautions that you
should be especially careful to observe:

152Here is a list of parts and tools you will
need on performing do-it-yourself main-
tenance. Remember all Toyota parts are
designed in metric sizes, so your tools
must be metric. Checking the engine oil level Parts (if level is low):
Engine oil API SH, Energy-Conserv-
ing IIº multigrade or ILSAC multigrade

Tools: Rag or paper towel
Funnel (only for adding oil)
Checking the engine coolant level Parts (if level is low): Ethylene-glycol antifreeze
Demineralized or distilled water
Tools: Funnel (only for adding coolant)

Tools: Rag or paper towel
Funnel (only for adding fluid) Checking power steering fluid Parts (if level is low):
Automatic transmission fluid DEXRON )
-II or -III
Tools: Rag or paper towel
Funnel (only for adding fluid)

Baking soda
Grease
Conventional wrench (for terminal clamp bolts)
Maintenance type batteriesÐ Parts (if level is low): Distilled water
Tools: Warm water
Baking soda
Grease
Conventional wrench (for terminal clamp bolts)
Coin (for vent plugs)

Aluminum wheel precautions
With the engine at operating tempera- ture and turned off, check the oil level
on the dipstick.
1. To get a true reading, the vehicle
should be on a
level spot. After turning off
the engine, wait a few minutes for the oil
to drain back into the bottom of the en-gine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick 'push it in as far
as it will go, or the reading will not be cor- rect.
4. Pull the dipstick out and look at the oil level on the end. If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine. Remove the oil filler cap and add engine
oil in small quantities at a time, checking the dipstick.
The approximate quantity of oil needed to fill between the low level and the full level
on the dipstick is indicated below for refer- ence.
When the level reaches within the correct range, install the filler cap hand-tight.
Oil quantity, L (qt., Imp. qt.): 1.5 (1.6, 1.3)

Avoid overfilling, or the enginecould be damaged.
Check the oil level on the dipstick
once again after adding the oil.

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
for at least 15 minutes and get im-
mediate medical attention. If pos-
sible, continue to apply water with
a sponge or cloth while en route to
the medical office.
If electrolyte gets on your skin,
thoroughly wash the contact area.
If you feel pain or burning, get
medical attention immediately. CAUTION
!
If electrolyte gets on your clothes,
there is a possibility of its soaking
through to your skin, so immedi- ately take off the exposed cloth-
ing and follow the procedure
above, if necessary.
If you happen to swallow electro-
lyte, drink a large quantity of wa-
ter or milk. Follow with milk of
magnesia, beaten raw egg or veg-
etable oil. Then go immediately
for emergency help.

164
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 acces-
sories are off before performing
maintenance.
When checking the battery, re-move the ground cable from the
negative terminal (-º mark) first
and 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 havesuch 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. Maintenance type batteryHydrometer color

NOTICE
Do not refill the battery with water.

166
ADDING DISTILLED WATER (MAINTE-
NANCE TYPE BATTERY ONLY)
1. Remove the vent plugs.
2. Add distilled water to cells needing fluid.
If the side of your battery is covered,
check the water level by looking down di-
rectly 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 theground cable.
3. Be sure the power switch on the re-
charger is off when connecting the char-ger cables to the battery and when dis-
connecting 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.
