conditioner automatically turns on (however,
the indicator light will not illuminate) if the
outside temperature is more than 36°F
(2°C) . If the air flow control dial is in
the
position for more than one minute,
the air conditioning system will continue to
operate until the fan control 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 the
position. This dehumidifies
the air which helps defog the windshield.
The
mode automatically turns off, al-
lowing outside air to be drawn into the pas-
senger compartment to further improve the
defogging performance.
Bi-level heating
This mode directs cooler air from the side and
center vents and warmer air from the floor outlets.
When the temperature control dial is moved to
the full hot or full cool position, the air between
the vents and the floor outlets is the same tem-
perature. 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.

conditioner automatically turns on (however,
the indicator light on the
button will
not come on) if the outside temperature is
more than 36°F (2°C) . If the air flow control
dial is in the
position for more than
one minute, the air conditioning system will
continue to operate until the fan control 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 the
position. This
dehumidifies the air which helps defog the
windshield. The
mode automatically
turns off, allowing outside air to be drawn
into the passenger compartment to further
improve the defogging performance.
Operating tips
Clear snow and ice from the wiper blades
and air inlet in front of the windshield. This
improves heater operation.

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.
AIR FLOW CHARTS
The following charts show the button and dial
positions for MAXIMUM AND QUICK heating,
cooling or defrosting. For additional information
on heating and cooling, see “Heater and air con-
ditioner (manual)” in this section. The air recir-
culation (
) button should always be in
the OFF position for heating and defrost-
ing.

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.
