Operating tips
cKeep the windows closed while the air con-
ditioner is in operation.
cAfter parking in the sun, drive for 2 or 3
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.
cThe 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.
cA 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.cIf 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 forMAXIMUM AND QUICKheating,

on heating and cooling see “Heater and air con-
ditioner” in this section.The air recirculation

WARNING
cThe air conditioner cooling function op-
erates only when the engine is running.
cDo 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.
cDo not use the recirculation mode for
long periods as it may cause the interior
air to become stale and the windows to
fog up.
