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.LHA4783

Operating tips
• Keep the windows closed while the air
conditioner 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 prevent
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 temperature
over the normal range, turn the air condi-
tioner off. For additional information, see
“If your vehicle overheats” (P. 6-19).
• 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
