Idling for a long period with the air
conditioning on in stop−and− go traffic.
Towing a trailer.
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
 Do not continue driving with an
overheated engine. See “If your ve-
hicle overheats” in Section 4.
The tachometer indicates engine speed
in thousands of rpm (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overrevving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get
into the red zone. This may cause
severe engine damage.

Fan speed selector
Turn the knob to adjust the fan speed—to
the right to increase, to the left to de-
crease.
Temperature selector
Turn the knob to adjust the temperature—
to the right to warm, to the left to cool.
Knowledge for the twotemperature 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.
Note: This manual dual temperature se-
lectors should generally only be used
as independent temperature settings for
the left and right.
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.
Air flow selector
Turn the knob to select the vents used for
air flow.1. Panel— Air flows mainly from the
instrument panel vents.
2. Bilevel— Air flows from both the floor
vents and the instrument panel vents.
When you set the temperature selector
setting at about the center, warm air
flows out of the floor vents and rela-
tively low −temperature air flows out of
the center and side vents.
3. Floor— Air flows mainly from the floor
vents.

4. Floor/Windshield—Air flows mainly
from the floor vents and windshield
vents.
Turning the air flow selector to the
floor/windshield position turns on the
defogging function with the purpose of
clearing the front view.
This position allows the air intake to
select FRESH automatically. This is to
clean up the front view more quickly.
If you want to return the setting to
RECIRCULATE mode, press the air in-
take selector button once again.
Press the “A/C” button for dehumidified
heating or cooling. This setting clears
the front view more quickly.
5. Windshield— Air flows mainly from the
windshield vents.
Turning the air flow selector to the
windshield position turns on the defog-
ging function with the purpose of clear-
ing the front view.
This position allows the air intake to
select FRESH automatically. This is to
clean up the front view more quickly.
If you want to return the setting to
RECIRCULATE mode, press the air in-
take selector button once again. Press the “A/C” button for dehumidified
heating or cooling. This setting clears
the front view more quickly.
For details about air flow selector settings,
see “—Air flow selector settings” de-
scribed below.
Air intake selector
Press the button to select the air source.
An indicator light will illuminate to show
which air intake mode is being selected. 1. Recirculate— Recirculates the air inside
the vehicle.
2. Fresh— Draws outside air into the sys-
tem.
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.

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.Heating
For best results, set controls to:
Fan speed— Any setting except “OFF”
Temperature— To w a r d s WARM
(red zone)
Air intake—FRESH (outside air)
Air flow—FLOOR
Air conditioning—OFF
For quick heating, select recirculated
air for a few minutes. To keep the
windows from fogging, select fresh af-
ter the vehicle interior has been
warmed.
Press the “A/C” button on for dehumidi-
fied heating.
Choose floor/windshield air flow to heat
the vehicle interior while defrosting or

clearing the front view.
When turning the air flow selector to wind-
shield or floor/windshield position, the air
intake selects FRESH automatically. This
is to clean up the front view more quickly.
If you want to return the setting to RE-
CIRCULATE mode, press the air intake
selector button once again.
Press the “A/C” button for dehumidified
heating or cooling. This setting clears the
front view more quickly.
On humid days, do not blow cold air
on the windshield—the difference be-
tween the outside and inside tempera-
tures could make the fogging worse. Defrosting

“AUTO” button
For automatic operation of the air condi-
tioning, press the “AUTO” button. “AUTO”
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 “AUTO” 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 “OFF” button.
Fan speed selector
Push the “>” (increase) or “<” (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
“
 ” side, to decrease it, press the “ ”
side.
“MAX COLD” appears when you adjust to
maximum cooling, and “MAX HOT” when
you adjust to maximum warming.
The temperature display changes between
“  C” and “ F” when the unit of the outside
temperature gauge is changed.
“DUAL” 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. “DUAL” 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 twotemperature se-
lector operation
