Adjust air flow direction for the driver’s and pas-
senger’s side windows
1, driver and passenger
2, or center3vent by moving the vent slide
and/or vent assemblies.
WARNING
● The air conditioner cooling function op-
erates only when the engine is running.
● Do not leave children or adults who
would normally require the assistance
of others alone in your vehicle. Pets
should also not be left alone. They
could accidentally injure themselves or
others through inadvertent operation of
the vehicle. Also, on hot, sunny days,
temperatures in a closed vehicle could
quickly become high enough to cause
severe or possibly fatal injuries to
people or animals.
● Do not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.

This mode is used to cool and dehumidify the air.
1. Push the
button to the off position.
2. Turn the air flow control dial to the
position.
3. Turn the fan control dial to the desired posi- tion.
4. Push the
button. The indicator light
comes on.
5. Turn the temperature control dial to the de- sired position. ●
For quick cooling when the outside tem-
perature is high, push the
button to
the on position (indicator light on) . Be sure
to return the
button to the off position
for normal cooling.
Dehumidified heating
This mode is used to heat and dehumidify the air.
1. Push the
button to the off position.
2. Turn the air flow control dial to the
position.
3. Turn the fan control dial to the desired posi- tion.
4. Push the

position.
2. Turn the fan control dial to the desired posi- tion. 3. Push the
button. The indicator light
comes on.
When the air flow control dial is in the
orposition, the air conditioner automati-
cally turns on (however, the indicator light will not
illuminate) if the outside temperature is more than
36°F (2°C) . If one of these positions is selected
for more than one minute, the air conditioning
system will continue to operate until the fan con-
trol dial is turned to OFF or the vehicle is shut off,
even if the air flow control dial is turned to a
position other than these positions. This dehu-
midifies the air which helps defog the windshield.
The
mode automatically turns off, allowing
outside air to be drawn into the passenger com-
partment to further improve the defogging perfor-
mance.
4. Turn the temperature control dial to the de- sired position.
Operating tips
●Keep the windows and moonroof (if so
equipped) closed while the air conditioner is
in operation.
● After parking in the sun, drive for two or three
minutes with the windows open to vent hot
air from the passenger compartment. Then,
close the windows. This allows the air con-
ditioner to cool the interior more quickly.
4-6Heater, air conditioner, audio and phone systems

●The air conditioning system should be
operated for approximately 10 minutes
at least once a month. This helps pre-
vent damage to the system due to lack
of lubrication.
● A visible mist may be seen coming from the
vents in hot, humid conditions as the air is
cooled rapidly. This does not indicate a mal-
function.
● If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. See “If your
vehicle overheats” in the “In case of
emergency” section of this manual.

on heating and cooling, see “Heater and air con-
ditioner (manual)” in this section. The air recir-
culation (

the OFF position for heating and defrost-
ing.

tinue to operate until the fan control dial is
turned to OFF, the vehicle is shut off, or the
A/C button is used to turn off the compres-
sor even if the air flow control dial is turned to
a position other than the
position.
This dehumidifies the air which helps defog
the windshield. The
mode automati-
cally turns off, allowing outside air to be
drawn into the passenger compartment to
further improve the defogging performance.
