Move the lever to select the air source.1. RecirculateÐ Recirculates the air inside
the vehicle.

tem. ºA/Cº button
To turn on the air conditioning, press the
ºA/Cº button. The ºA/Cº button indicator
will come on. To turn the air conditioning
off, press the button again.
If the ºA/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.

ÐAir flow selector settings
ÐOperating tips
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
conditioning to cool the interior more
quickly.
Make sure the air intake grilles 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 air
temperature 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
ºHIº for a minute to help clear the in-
take ducts of snow or moisture. This
can reduce the amount of fogging on
the windows.

Turning the air flow selector knob to the
windshield position turns on the defroster-
linked air conditioning. This is to clear up
the front view more quickly.
When the ºA/Cº button is not pressed in,
turning the air flow selector knob to anoth-
er position turns off the air conditioning.
On humid days, do not blow cold air
on the windshieldÐthe difference be-
tween the outside and inside tempera-
tures could make the fogging worse.

If air flow control is not satisfactory, check
the side vents. The side vents may be
opened or closed as shown.

Keep the trunk lid closed while
driving. An open or unsealed trunk
lid may cause exhaust gases to be
drawn into the vehicle. If you must
drive with the trunk lid open to ac-
commodate a large object, close the
windows, open all the instrument
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 con-
trol 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 clear of snow, leaves, or oth-
er obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open and the trunk lid closed. Have
the cause immediately located and
corrected.
FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are as
follows.
Oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil
is left on the cylinder wall when a pis-
ton moves downwards in the cylinder.
High negative pressure generated when
the vehicle is decelerating sucks some
of this oil into the combustion chamber.
This oil as well as some part of the oil
film left on the cylinder wall is burned
by the high temperature combustion
gases during the combustion process.
Oil is also used to lubricate the stems
of the intake valves. Some of this oil
is sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by high- speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge
the true level accurately.
As an example, if a vehicle is used for
repeated short trips, and consumes a nor-
mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This
is because the oil is gradually becoming
diluted with fuel or moisture, making it
appear that the oil level has not changed.
