∙ 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

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.
