5. Turn the temperature control dial to the desired position.
Dehumidified defogging
This mode is used to defog the windows
and dehumidif y the air.
1. Press the
front defroster button.
2. Turn the
fan speed control dial to
the desired position. When the
orpositions are se-
lected, the air conditioner automatically
turns on if the outside temperature is ap-
proximately at or below freezing. The air
conditioning system will continue to oper-
ate until the
fan speed control dial is
turned to OFF, the air conditioner is turned
OFF, or the vehicle is shut off. If a position
other than the
front defrost air flow
button is selected, the A/C compressor will
not turn off even if the user had selected
A/C off prior to entering defrost. In
front defrost orfoot defrost the indi-
cator light on the A/C button will not turn
on if the user had selected A/C off. Turning
off the air conditioning via the A/C button is
not allowed in this mode. If the A/C button
indicator was on when entering this mode,
and the A/C button is selected in this
mode, the A/C button indicator will turn off,
but the A/C compressor will still be auto-
matically enabled. This dehumidifies the air
which helps defog the windshield. The

Operating tips
• Keep the windows closed while the airconditioner is in operation.
• Af ter parking in the sun, drive for 2 or 3 minutes with the windows open to vent
hot air from the passenger compart-
ment. Then, close the windows. This al-
lows the air conditioner to cool the inte-
rior more quickly.
• 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 ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
• If the engine coolant temperature
gauge indicates engine coolant tem-
perature over the normal range, turn
the air conditioner off. For additional
information, see “If your vehicle over-
heats” (P. 6-12).
AIR FLOW CHARTS
The following charts show the button and
dial positions for MAXIMUM AND QUICK
heating, cooling or defrosting. For addi-
tional information on heating and cooling,
see “Heater and air conditioner (manual)”
(P. 4-28). The air recirculation (
) but-
ton should always be in the OFF position
for heating and defrosting.

WARNING
• The air conditioner cooling function
operates only when the engine is
running.
• Do not leave children or adults who
would normally require the assis-
tance of others alone in your vehicle.
Pets should also not be lef t alone.
They could accidentally injure them-
selves 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 inte-
rior air to become stale and the win-
dows to fog up.
NOTE:
• Odors from inside and outside the ve- hicle can build up in the air conditioner
unit. Odor can enter the passenger
compartment through the vents.
• When parking, set the heater and air conditioner controls to turn off air re-
circulation to allow fresh air into the
passenger compartment. This should
help reduce odors inside the vehicle.LHA3575

cator light on the A/C button indicator will
not turn on if the user had selected A/C
off prior to entering this mode. Turning off
the air condition via the A/C button is not
allowed in this mode. If the A/C button
indicator was on when entering this
mode, and the A/C button is selected in
this mode, the A/C compressor will still be
automatically enabled. The air recircula-
tion mode automatically turns off, allow-
ing outside air to be drawn into the pas-
senger compartment to further improve
the defogging performance.
Remote Engine Start with
Intelligent Climate Control (if so
equipped)
Vehicles equipped with automatic climate
controls and Remote Engine Start function
may go into automatic heating or cooling

OPERATING TIPS
The sunload sensor (if so equipped)O1, lo-
cated on the top center of the instrument
panel, helps the system maintain a con-
stant temperature. Do not put anything on
or around this sensor. • When the climate system is in automatic
operation and the engine coolant tem-
perature and outside air temperature are
low, the air flow outlet may default to de-
froster mode for approximately 2 min-
utes 30 seconds. This is not a malfunc-
tion. Af ter the engine coolant
temperature warms up, the air flow outlet
will return to foot mode and operation will
continue normally.
• When the outside and interior cabin tem- peratures are moderate to high, the in-
take setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may occur
when previous climate setting was sys-
tem off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, air flow
outlet will return to previous settings, and
operation will continue normally. To exit,
press any climate control button.
• Keep the windows closed while the air conditioner is in operation.
• If you feel that the air flow mode you have selected and the outlets the air is coming
out do not match, select the
mode.
