NOTICE
Avoid overfilling, or the engine
could be damaged.
Check the oil level on the dipstick
once again after adding the oil.
ENGINE OIL SELECTION
Use API SH, ”Energy-Conserving II” or
SJ, ”Energy −Conserving” multigrade engine
oil or ILSAC multigrade engine 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 engine
may become difficult to start, so SAE
5W-30 engine oil is recommended.
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 SJ. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W-30. ”Energy-
Conserving” shown in the lower portion,
indicates that the oil has fuel-saving capa-
bilities.

T100(U)181
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container. Look at the see-through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the ”FULL” and ”LOW” lines on the
reservoir. If the level is low, add ethyl-
ene-glycol type coolant.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the ”LOW” line, add
coolant. Bring the level up to the ”FULL”
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
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
Your coolant must contain ethylene-glycol
antifreeze. In addition to preventing freez-
ing and subsequent damage to the engine,
this will also prevent corrosion. Further
supplemental inhibitors or additives are
neither needed nor recommended.
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
recommend 50% solution be used for your
Toyota, or a sufficient quantity to provide
protection to about –35
°C (–31 °F).
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
Checking the engine coolant level

T100(U)
182
Checking brake fluid
To check the fluid levels, simply look at
the see-through reservoirs. The level
should be between the ”MAX” and
”MIN” 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 reservoir
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 from
damaging the parts or paint.
Checking power steering fluid
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 °C–80 °C or 104 °F–175 °F). You may
also check the level when the fluid is cold
(about room temperature, 0 °C–40 °C or
32 °F–104 °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 counterclockwise and wipe the dipstick
clean.

—Checking battery exterior
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 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 accesso-
ries are off before performing main-
tenance.
When checking the battery, remove
the ground cable from the negative
terminal (”–” mark) first and rein-
stall it last.
Take care no solution gets into the
battery when washing it.
Be careful not to cause a short cir-
cuit with tools.

CHECKING BY THE HYDROMETER
Check the battery condition by the
hydrometer color.

Battery recharging precautions
During recharging, the battery is pro-
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 (5A or less).
Charging at a quicker rate is dan-
gerous. The battery may explode,
causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.
Checking and replacing fuses

T100(U)193
Adding washer fluid
If any washer does not work, the wash-
er tank may be empty. Add washer
fluid.
You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below freezing point, use
washer fluid containing antifreeze. This
product is available at your Toyota dealer
and most auto parts stores. Follow the
manufacturer ’s directions for how much to
mix with water.
NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.NOTICE
5VZ
−FE engine vehicles for Canada:
When adding washer fluid, be careful
not to spill the fluid over the daytime
running light resistor.
Replacing light bulbs—
The following illustrations show how to
gain access to the bulbs. When replacing
a bulb make sure the ignition switch and
light switch are off. Use bulbs with the
wattage ratings given in the table.
CAUTION
Halogen bulbs have pressurized gas
inside and require special handling.
They can burst or shatter if scratched
or dropped. Hold a bulb only by its
plastic or metal case. Do not touch
the glass part of a bulb with barehands.
NOTICE
Only use a bulb of the listed type.
