air flow.
1. Panel ÐAir flows mainly from the in-
strument panel vents.
2. Bi-level ÐAir flows from both the floor
vents and the instrument panel vents.
3. Floor ÐAir flows mainly from the floor

4. Floor/Windshield ÐAir flows mainly
from the floor vents and windshield vents.
5. Windshield ÐAir flows mainly from
the windshield vents. For details about air flow selector settings, see the illustration after A/Cº button.

Moving the airflow selector lever to wind-
shield position turns on the defroster-
linked air conditioning. At this time, the
A/Cº button indicator comes on regard- less of whether or not the A/Cº button is pressed in. This is to clear up the front
view more quickly. When the A/Cº button is not pressed in, moving the air flow control lever to anoth-
er position turns off the air conditioning.

To cool off your Toyota after it has been
parked in the hot sun, drive with the
windows open for a few minutes. This
vents the hot air, allowing the air condi-
tioning to cool the interior more quickly.
Make sure the air intake g rilles in front
of the windshield are not blocked (by
leaves or snow, for example).
On humid days, do not blow cold air on
the windshield. The windshield could
fog up because of the difference in airtemperature on the inside and outside
of the windshield.
Keep the area under the front seats
clear to allow air to circulate through-out the vehicle.
On cold days, move the fan speed to
HIº for a minute to help clear the in-
take ducts of snow or moisture. This
can reduce the amount of fogging onthe windows.

Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic igni-tion system/distributor ignitionsystem or fuel systems could
cause an extremely high three- way catalytic converter tempera-ture.
If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check-up as soon
as possible. Remember, your To-yota dealer knows your vehicleand its three-way catalytic con-
verter system best.
To ensure that the three-way cata-lytic converter and the engine
emission control system operateproperly, your vehicle must re-ceive the periodic inspections re-
quired by the Toyota Maintenance
Schedule. For scheduled mainte- nance information, refer to the
separate Owner's Manual Sup-
plement/Maintenance Scheduleº.
CAUTION!
Avoid inhaling the engine ex-
haust. It contains carbon monox-
ide, which is a colorless and odor-
less gas. It can cause uncon-
sciousness or even death.
Make sure the exhaust system
has no holes or loose connec-
tions. The system should be
checked from time to time. If you
hit something, or notice a change
in the sound of the exhaust, have
the system checked immediately.
Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot escape, making this a paticularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine
running. If it is unavoidable, how-
ever, do so only in an unconfined
area and adjust the heating or
cooling system to force outside air into the vehicle.Keep the back door and back win-
dow closed while driving. An open
or unsealed back door and back
window, may cause exhaust gases to be drawn into the vehicle. If you
must drive with the trunk lid open
to accommodate a large object,
close the windows, open all the in- strument panel vents and have the
heating or cooling system deliver fresh air into the vehicle by turning
the fan to high speed with the air
intake control set at the outside air position.
To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the wind-
shield cl ear of snow, leaves, or oth-
er obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open and the back door and back
window closed. Have the cause im-
mediately located and corrected.
Engine exhaust cautions

165
If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a
loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure 0
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in Pº
(automatic) or neutral (manual) and
apply the parking brake. Turn off the
air conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the engine.
Wait until the steam subsides before
opening the hood. If there is no coolant
boiling over or steam, leave the engine running.
To help avoid personal injury, keep
the hood closed until there is no steam. Escaping steam or coolant is
a sign of very high pressure. CAUTION
! 3. Visually check to see if the engine
drive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from
the radiator, hoses, and under the ve-
hicle. However, note that water drain-ing from the air conditioning is normal if it has been used.
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts. CAUTION
!
4. If the engine drive belt is broken of the coolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as- sistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quick-
ly by running it at about 1500 rpm for
a few minutes with the accelerator
pedal lightly depressed.
6. Check the coolant reservoir. If it is dry, add coolant to the reservoir while the
engine is running. Fill it about half full.
Do not attempt to remove the
radiator cap when the engine and
radiator are hot. Serious injury
could result from scalding hot fluid
and steam blown out underpressure. CAUTION
!
7. After the engine coolant temperature has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You should have it checked as
soon as possible at your Toyota deal-
er.
