If you turn the air flow selector to the
another position, the air intake mode
returns to FRESH mode automatically.
For details about air flow selector settings,
see the illustration after ªA/Cº button.
Air intake selector
The air intake selector button is used to
switch the air intake FRESH mode that
draws outside air into the system and
RECIRCULATED mode that recirculates
the air inside vehicle.
To turn the air source to RECIRCULATED
mode, press the button. The indicator will
come on. To turn the air source to FRESH
mode, press the button again. The indica-
tor will go off.
To prevent fogging up of the windshield,
the air intake mode may change automati-
cally to FRESH depending on the condi-
tion of the air conditioning system.ªA/Cº button
To turn on the air conditioning, press the
ªA/Cº button. The ªA/Cº button indicator
will come on. To turn the air conditioning
off, press the button again.
If the ªA/Cº button indicator flashes, there
is a problem in the air conditioning system
and the air conditioning automatically
shuts off. If this happens, take your ve-
hicle to a Toyota dealer for service.

If you perform maintenance by yourself,
be sure to follow the correct procedure
given in this section.
You should be aware that improper or in-
complete servicing may result in operating
problems.
Performing do±it±yourself maintenance
during the warranty period may affect your
warranty coverage. Read the separate
Toyota Warranty statement for details and
suggestions.
This section gives instructions only for
those items that are relatively easy for an
owner to perform. As explained in Section
6, there are still a number of items that
must be done by a qualified technician
with special tools.
For information on tools and parts for do±
it±yourself maintenance, see ªParts and
toolsº.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that
you should be especially careful to ob-
serve:CAUTION

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, radiator,
exhaust manifold and spark plug
boots, etc.Ðwill be hot. So be care-
ful 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 flammable.

Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.

Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.

Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling fans
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 your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.

Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move 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 dealer or
a service station for information
concerning recycling or disposal.
NOTICE
Remember that battery and ignition
cables carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.
Add only demineralized or distilled
water to fill the radiator. And if you
spill some of the coolant, be sure
to wash off with water to prevent it
from damaging the parts or paint.
Do not allow dirt or anything else
to fall through the spark plugholes.
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 iridium±tipped spark
plugs by cleaning or regapping.
Do not overfill automatic transmis-
sion fluid, or the transmission
could be damaged.
Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.
Parts and tools
Here is a list of parts and tools you will
need on performing do±it±yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.
Checking the engine oil level
Parts (if level is low):

Engine oil API grade SJ,
ªEnergy±Conservingº or ILSAC
multigrade having viscosity proper for
your climate
Tools:

Rag or paper towel

Funnel (only for adding oil)
Checking the engine coolant level
Parts (if level is low):

ªTOYOTA Long Life Coolantº or equiva-
lent
See Section 7±2 for details about cool-
ant type selection.

Demineralized or distilled water
Tools:

Funnel (only for adding coolant)

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. ªEnergy±
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 ªFULLº and ªLOWº lines on the
reservoir. If the level is low, add ethyl-
ene±glycol type coolant for a proper
corrosion protection of aluminum com-
ponents.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the ªLOWº line, add
coolant. Bring the level up to the ªFULLº
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, engine coolant filler cap,
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.
