∙ When theposition is selected, the
air conditioner automatically turns on if
the outside temperature is more than
36°F (2°C). 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 im-
prove 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.
AIR CONDITIONER OPERATION
Start the engine, turn thefan speed
control dial to the desired position, and

∙ Af ter parking in the sun, drive for 2 or3 minutes with the windows open to
vent hot air from the passenger com-
partment. Then, close the windows.
This allows the air conditioner to cool
the interior 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 in-
formation, refer to “If your vehicle over-
heats” in the “In case of emergency”
section of this manual.
∙ When Remote Engine Start (if so equipped) is activated, the manual cli-
mate control system will default to the
last used heating or cooling mode.AIR FLOW CHARTS
The following charts show the button and

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.

Start the engine and operate the controls
to activate the air conditioner.
NOTE:∙ Odors from inside and outside the ve-
hicle can build up in the air condi-
tioner unit. Odor can enter the pas-
senger 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.

matically. Air flow distribution, air intake
control and fan speed are also con-
trolled automatically.
∙ 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 malfunction.
3. You can individually set driver’s and front passenger’s side temperature us-
ing each temperature control dial. To
synchronize the driver’s and front pas-
