anism
Check the lock release button of the se-
lector lever for proper and smooth opera-
tion. On a safe incline, check that your ve-
hicle is held securely with the selector
lever in ºPº position and all brakes re-
leased.
IN THE ENGINE COMPARTMENT
Items listed below should be checked
from time to time, e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7-3 for additional infor-
mation.ProCarManuals.com

160Engine coolant level
Make sure the coolant level is between
the FULLº and LOWº lines on the see-
through
reservoir when the engine is cold.
See Chapter 7-2 for additional informa-
tion.
Battery electrolyte level
Make sure the electrolyte level of all bat-
tery cells is between upper and lower level
lines on the case. Add only distilled water
when replenishing. See Chapter 7-3 for
additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See Chapter 7-2 for additional informa-
tion.
Engine oil level
Check the l evel on the dipstick with the en-
gine turned off and the vehicle parked on
a level spot. See Chapter 7-2 for addition-
al information.
Power steering fluid level
Check the level through the reservoir. The
level should be in the HOTº or COLDº
range depending on the fluid t emperature.
See Chapter 7-2 for additional informa-
tion.
Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See engine exhaust cautions in
Part 2.) Be on the alert for changes in perfor-
mance, sounds, and visual tip-offs
that in-
dicate service is needed. Some important
clues are as follows:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)

Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)

Flat-looking tire; excessive tire squeal
when cornering; uneven tire wear

Vehicle pulls to one side when driving
straight on a level road

Strange noises related to suspension
movement

Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking

Engine coolant temperature continual-
ly higher than normal If you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
Do not continue driving with the ve-
hicle unchecked. It could result in
serious vehicle damage and possi-
bly personal injury.
CAUTION

Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the engine cooling fan
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 water to fill the radiator. And
if you spill some of the coolant, besure 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.
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.
NOTICEBe careful not to scratch the glasssurface with the wiper frame.
When closing the engine hood,
check to see that you have not for-gotten any tools, rags, etc.

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.
CAUTION
Be careful not to touch the hot
exhaust manifold.!
If the oil level is below or only slightly
above the low level line, add engine oil
of the same type as already in the en-
gine.
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 engine could be damaged.
Check the oil level on the dipstick
once again after adding the oil.

Look at the see-through coolant res-
ervoir when the engine is cold. The
coolant level is satisfactory if it is be-
tween the FULLº and LOWº lines on
the reservoir. If the level is low, add
ethylene-glycol type coolant.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the LOWº line, add
coolant. Bring the level up to the FULLº
line.
Use only ethylene-glycol type coolant.
See information in the next column.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the ra-
diator, hoses, radiator cap
and drain cock
and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check for
leaks in the cooling system.
To prevent burning yourself, do not
remove the radiator cap when the
engine is hot.
CAUTION!
Coolant type selection
Your coolant must contain ethylene-gly-
col antifreeze. In addition to preventing
freezing and subsequent damage to the
engine, this will also prevent corrosion.
Further supplemental inhibitors or addi-
tives are neither needed nor recom-
mended.
Read the antifreeze container for informa-
tion on freeze protection. Follow the
manufacturer 's directions for how much
to mix with water. The total capacity of the
cooling system is given in Part 8. We rec-
ommend 50% solution be used for your
Toyota, or a sufficient quantity to provide
protection to about -35 C (-31 C).
Do not use alcohol type antifreeze
or plain water alone.
NOTICE
To check the fluid level, simply look at
the see-through reservoir. The level
should be between the MAXº and
MINº 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.

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 (к 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:
maintenance type and non-mainte-
nance 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.

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 the
ground 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.
