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 in-
formation.
Engine coolant level
Make sure the coolant level is between
the Fº and Lº lines on the see- through
reservoir when the engine is cold. See
Chapter 7- 2 for additional information.Battery electrolyte level
Make sure the electrolyte level of all bat-
tery cells is between upper and lower lev-
el 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 information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level spot. See Chapter 7- 2 for addi-
tional information.
Power steering fluid level (5VZ- FE en-
gine)
Check the level on the dipstick. The level
should be in the HOTº or COLDº range
depending on the fluid temperature. See
Chapter 7- 2 for additional information.
Power steering fluid level (2UZ- FE en-
gine)
Check the level through the reservoir. The
level should be in the HOTº or COLDº
range depending on the fluid temperature.
See Chapter 7- 2 for additional information.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
indicate service is needed. Some impor-
tant 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 monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)

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 continually
higher than normal

Engine continually runs hot; oil pres-
sure gauge stays low
If you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.

NOTICE

Remember that battery and ignitioncables carry high currents or volt-ages. Be careful of accidentallycausing a short circuit.

Add only demineralized or distilledwater to fill the radiator. And if youspill some of the coolant, be sure
to wash it off with water to preventit from damaging the parts or paint.

Do not allow dirt or anything elseto fall through the spark plug holes.

Do not pry the outer electrode of a
spark plug against the center elec-trode.

Use only spark plugs of the speci-fied type. Using other types willcause engine damage, loss of per-
formance or radio noise.

Do not overfill automatic transmis-sion fluid, or the transmissioncould be damaged.

Do not drive with the air cleaner
filter removed, or excessive enginewear could result. Also backfiringcould cause a fire in the engine
compartment.

Be 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.

Checking the engine oil level
Low level Full level
Add oil O.K. Too full
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 engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstickÐpush it in as far as it will go, or the reading will not be
correct.
4. Pull the dipstick out and look at the oil level on the end.
CAUTION
Be careful not to touch the hot ex-
haust manifold.
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 ref-
erence.
When the level reaches within the correct
range, install the f iller cap hand- tight.
Oil quantity, L (qt., lmp. qt.): 5VZ- FE engine 1.2 (1.3, 1.1)

NOTICE

Avoid overfilling, or the engine
could be damaged.

Check the oil level on the dipstickonce again after adding the oil.

Look at the see- through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the Fº and Lº lines on the reservoir.
If the level is low, add ethylene- glycol
type coolant for a proper corrosion
protection of aluminum components.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the Lº line, add
coolant. Bring the level up to the Fº line.
Always use ethylene- glycol type coolant
for a proper corrosion protection of alumi-
num components. 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
radiator, 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.CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
Coolant type selection
Use of improper coolants may damage
your engine cooling system. Your coolant
must contain ethylene- glycol type coolant
for a proper corrosion protection of your
engine that contains aluminum
components. Use TOYOTA Long Life
Coolantº or equivalent.
In addition to preventing freezing and
subsequent damage to the engine, this
type of coolant will also prevent corrosion.
Further supplemental inhibitors or additives
are neither needed nor recommended.
Read the coolant container for information
on freeze protection. Follow the manufac-
turer's directions for how much to mix
with plain water (preferably demineralized
water or distilled water). The total capacity
of the cooling system is given in Part 8. We recommend to use 50% solution for
your Toyota, to provide protection down to
about -35
C (- 31 F). When it is extreme-
ly cold, to provide protection down to
about -50 5C (- 58 5F), 60% solution is rec-
ommended. Do not use more than 70%
solution for better coolant performance.NOTICE
Do not use alcohol type antifreeze or
plain water alone.

Checking brake fluid
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. If the level is low, add SAE J1703 or
FMVSS No.116 DOT 3 brake fluid to the
brake reservoir.
Remove and replace the reservoir cover
by hand. Fill the brake fluid to the dotted
line. This brings the fluid to the correct
level when you put the cover back on.
Use only newly opened brake fluid. Once
opened, brake fluid absorbs moisture from
the air, and excess moisture can cause a
dangerous loss of braking.
CAUTION
Take care when filling the r
eservoir
because brake fluid can harm your
eyes and damage painted surfaces. If
fluid gets in your eyes, flush your
eyes with clean water.
NOTICE
If you spill the fluid, be sure to wash it off with water to prevent it fromdamaging the parts or paint.
If cold add
If cold O.K.
If hot add If hot O.K.
Check the fluid level on the dipstick. If
necessary, add automatic transmission
fluid DEXRON II or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (40 5CÐ80 5C or 104 5FÐ175 5F). You
may also check the level when the fluid
is cold (about room temperature,
0 5CÐ40 5C or 32 5FÐ104 5F) if the engine
has not been run for about five hours.
a. Clean all dirt from outside of the reser-
voir tank.
b. Remove the filler cap by turning it
counterclockwise and wipe the dipstick
clean.

c. Reinstall the filler cap.
d. Remove the filler cap again and look at
the fluid level. If the fluid is cold, the
level should be in the COLDº range on
the dipstick. Similarly, if it is hot, the fluid
level should be in the HOTº range. If the
level is at the low side of either range,
add automatic transmission fluid
DEXRONII or III to bring the level within
the range.
e. After replacing the filler cap, visually
check the steering box case, vane pump
and hose connections for leaks or dam-
age.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.

Avoid overfilling, or the power steer-
ing could be damaged.

Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRON II or III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little
more in frigid temperatures), the fluid is
hot (60 CÐ80 C or 140 FÐ175 F). You
may also check the level when the fluid
is cold (about room temperature,
10 CÐ30 C or 50 FÐ85 F) if the engine
has not been run for about five hours. Clean all dirt from outside of the reservoir
tank and look at the fluid level. If the fluid
is cold, the level should be in the COLDº
range. Similarly, if it is hot, the fluid level
should be in the HOTº range. If the level
is at the low side of either range, add
automatic transmission fluid DEXRON
II
or III to bring the level within the range.
To remove the filler cap, turn it c ounter-
clockwise and lift up. To reinstall it, turn
it clockwise. After replacing the filler cap,
visually check the steering box case, vane
pump and hose connections for leaks or
damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer- ing could be damaged.

ÐChecking battery exterior
TerminalsGround cable
Hold- down clamp
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 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 nutsÐbut 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 accesso-ries are off before performing main-tenance.

When checking the battery, remove
the ground cable from the negativeterminal (- 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.

ducing hydrogen gas.
Therefore, before recharging:1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Be sure the power switch on the re- charger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION

Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.

Only do a slow charge (5 A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
