AUTOº button
For automatic operation of the air condi-
tioning, press the AUTOº button. AUTOº
will appear on the display to show that
the automatic operation mode has been
selected.
In the automatic operation mode, the air
conditioning selects the most suitable fan
speed, air flow, air intake and on- off of
the air conditioning according to the tem-
perature.
When you press the AUTOº button with
the air intake mode at FRESH, internal
circulation may be applied for maximum
cooling.
You may use manual controls if you want
to select your own settings.
To turn off the automatic operation, press
the OFFº button.
Fan speed selector
Push the >º (increase) or <º (decrease)
side of the button to adjust the fan speed.
In automatic operation, you do not have
to adjust the fan speed unless you desire
another fan speed mode.Temperature selector
To increase the temperature, press the


º side, to decrease it, press the  º
side.
MAX COLDº appears when you adjust to
maximum cooling, and MAX HOTº when
you adjust to maximum warming.
The temperature display changes between
  Cº and  Fº when the unit of the outside
temperature gauge is changed.
DUALº button
This switch is used to set the tempera-
tures independently for the driver 's seat
and front passenger seat.
Pushing the button changes the mode
from independent and linked.
Independent mode: Temperatures can be
set independently for the driver 's seat and
front passenger 's seat. DUALº will appear
on the display to show that the indepen-
dent mode has been selected.
Linked mode: The same temperature is
set for the driver's seat and front passen-
ger 's seat.
When the temperature for the front pas-
senger 's seat is changed in linked mode,
the mode is changed automatically to in-
dependent mode. Knowledge for the two- temperature se-
lector operation
This air conditioning system has two inde-
pendent temperature selectors: left and
right (for the use of driver and front pas-
senger respectively).

There are cases where the temperature
of the airflow may not accurately corre-
late on the driver and front passenger
side according to circumstances, even
if the left and right temperature selec-
tors are set at the same temperature.
If this situation occurs, use the fine
tune operation to adjust the air temper-
ature on one side.

There are cases where one or both of
the airflow temperatures may not accu-
rately correlate with the set tempera-
ture according to circumstances, when
the airflow temperature settings on the
left and right are substantially different.
For example, if the left controller is set
at central or neutral temperature while
the right one is set at maximum heat-
ing or maximum cooling, or vice versa.
If this situation occurs, use the fine
tune operation to adjust the air temper-
ature on each side.
OFFº button
Push the OFFº button to turn off the air
conditioning system.

scribed below.
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 RE-
CIRCULATED mode that recirculates the
air inside vehicle.
Press the button to select the air source.
The air intake mode which is being se-
lected is shown on the display.
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.
For example, when the ambient tempera-
ture is low, the air intake mode may
change automatically to FRESH. This is
not a malfunction.A/Cº button
To turn on the air conditioning, press the
A/Cº button. The A/Cº button indicator
will come on. To turn the air conditioning
off, press the button again.
If the A/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 your Toyota dealer for service.

ÐAir flow selector settingsÐOperating 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, push the fan speed se-
lector to adjust the fan speed high for
a minute to help clear the intake ducts
of snow or moisture. This can reduce
the amount of fogging on the windows.

When driving on dusty roads, close all
windows. If dust thrown up by the ve-
hicle is still drawn into the vehicle after
closing the windows, it is recommended
that the air intake selector be set to
FRESH and the fan speed selector to
any setting except OFFº.

If following another vehicle on a dusty
road, or driving in windy and dusty
conditions, it is recommended that the
air intake selector be temporarily set to
RECIRCULATE, which will close off the
outside passage and prevent outside
air and dust from entering the vehicle
interior.

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 the that 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. The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it
appear that oil is excessively consumed
after driving at high speeds.
IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine troubledue to insufficient oil.
For detailed information on oil level check,
see Checking the engine oil levelº in Sec-
tion 7- 2.

Backing with a trailer is difficult and
requires practice. Grip the bottom of
the steering wheel and move your hand
to the left to move the trailer to the
left. Move your hand to the right to
move the trailer to the right. (This pro-
cedure is generally opposite to that
when backing without a trailer). Also,
just turn the steering wheel a little at
a time, avoiding sharp or prolonged
turning. Have someone guide you when
backing to reduce the risk of an acci-
dent.

Because stopping distance may be in-
creased, vehicle- to- vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of
speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as
you may skid, resulting in jackknifing
and loss of control. This is especially
true on wet or slippery surfaces.

Avoid jerky starts or sudden accelera-
tion.

Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.

Remember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this by
making a larger than normal turning
radius with your vehicle.

Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed. Steer
straight ahead. If you make no extreme
correction with the steering or brakes,
the vehicle and trailer will stabilize.

Be careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.

In order to maintain engine braking effi-
ciency do not use overdrive.

Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over
30
C [85 F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to If
your vehicle overheatsº in 4 of this
manual.

Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in Pº. Avoid park-
ing on a slope with a trailer, but if it
cannot be avoided, do so only after
performing the following:
