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. CAUTION
!
Do not get under your vehicle with
just the body jack supporting it.
Always use automotive jack
stands or other solid supports.
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 thereach 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 cable 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 overfill automatic trans-mission fluid, transfer oil and
power steering fluid, or the trans-mission, transfer and power stee-
ering could be damaged.
Do not drive with the air cleaner fil-ter removed, or excessive enginewear could result. Also backfiring
could cause a fire in the enginecompartment.
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.

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 dipstick 'push 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.
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 filter 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 line and the full
level on the dipstick is indicated below for reference. 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.
NOTICE

176ENGINE OIL SELECTION Use API SH, Energy-Conserving IIº mul- tigrade engine oil or ILSAC multigrade en-
gine oil. Recommended viscosity (SAE):
SAE 5W-30 is the best choice for your
vehicle, for good fuel economy and
good starting in cold weather.
If you use SAE 10W-30 engine oil in
extremely low temperatures, the en-
gine may become difficult to start, so
SAE 5W-30 engine oil is recom-mended.
Oil identification marks
Either or
both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any -
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SH. The center
portion of the label shows the SAE viscosity
grade such as SAE 5W- 30. Energy- Con-
serving IIº shown in the lower portion, indi-
cates that the oil has fuel- saving capabili-
ties. Oils marked Enegy- Conserving IIº
will have higher fuel- saving capabilities
than oil marked Energy- Conservingº.The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certification Mark is displayed on the front
of the container.

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 en-
gine is hot.
CAUTION! Coolant type selection
Your coolant must contain ethylene-gly- col antifreeze. In addition to preventingfreezing 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 provideprotection 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.
Checking the engine coolant level
Checking brake fluid

178If 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 lev-
el 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 reservoir
because brake fluid can harm your
eyes and damage painted surfaces. If
fluid gets in your eyes, flush your
eyes with clean water.
If you spill the fluid, be sure to wash
it off with water to prevent it from
damaging the parts or painting.
NOTICE
Check the fluid level on the dipstick. If
necessary, add automatic transmis-
sion 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 C ' 80 C or 140 F ' 175 F). You
may also check the level when the fluid is
cold (about room temperature, 10 C '
30 C or 50 F ' 85 F) 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 coun- terclockwise 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. 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 transmis-
sion fluid DEXRON -II or III to bring the
level within 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 steering could be damaged.
