Pressing the button once again returns the
air flow mode to the last one used.
Pressing the windshield air flow button
turns on the defroster- linked air condition-
ing. At this time, the A/Cº button indicator
comes on regardless of whether or not the
A/Cº button is pressed in. This is to
clean up the front view more quickly.
When the A/Cº button is not pressed in.
pressing anther air flow button turns off
the air conditioning.

Clock
The digital clock indicates the time.

position.
To reset the hour: Push the Hº button.
To reset the minutes: Push the Mº button.
If quick adjustment to a full hour is de-
sired, push the :00º button.
For example, if the :00º button is de-
pressed when the time is between
1:01Ð1:29, the time will change to 1:00.
If the time is between 1:30Ð1:59, the
time will change to 2:00.If the electrical power source has been
disconnected from the clock, the time dis-
play will automatically be set to 1:00 (one

API service symbol
ILSAC certification mark
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-
Conservingº shown in the lower portion,
indicates that the oil has fuel- saving ca-
pabilities.
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 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 Section
8.We recommend to use 50% solution for
your Toyota, to provide protection down to
about -35C (- 31F). When it is extreme-
ly cold, to provide protection down to
about -50C (- 58F), 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.
