illuminate. After ten minutes, the system will
return to normal AUTO mode function and the
LED will turn off.
NOTE:
• When the ignition switch is turned to the
LOCK position, the recirculation feature
will be cancelled.
• In cold weather, use of the Recirculation
mode may lead to excessive window fog-
ging. The Recirculation mode is not al-
lowed in the floor, defrost, or defrost/floor
mode in order to improve window clear-
ing. Recirculation will be disabled auto-
matically if these modes are selected.
• Extended use of recirculation may cause
the windows to fog. If the interior of the
windows begins to fog, press the Recir-
culation button to return to outside air.
Some temp/humidity
cause captured interior air to condense
on windows and hamper visibility. For
this reason, the system will not allow
Recirculation to be selected while in floor,
defrost, or defrost/floor mode. Attempting
to use the recirculation while in these
modes will cause the LED in the control
button to blink and then turn off.
• Most of the time, when in Automatic Op-
eration, you can temporarily put the sys-
tem into Recirculation Mode by pressing
the Recirculation button. However, under
certain conditions, while in Automatic
Mode, the system is blowing air out the
defrost vents. When these conditions are
present, and the Recirculation button is
pressed, the indicator will flash and then
turn off. This tells you that you are unable
to go into Recirculation Mode at this time.
If you would like the system to go into
Recirculation Mode, you must first move
the Mode knob to Panel, Panel/Floor and
then press the Recirculation button. This
feature reduces the possibility of window
fogging.

Operating Tips
NOTE:
Refer to the chart at the end of this section
for suggested control settings for various
weather conditions.
Summer Operation
The engine cooling system in air-conditioned
vehicles must be protected with a high-quality
antifreeze coolant to provide proper corrosion
protection and to protect against engine over-
heating. A solution of 50% ethylene glycol
antifreeze coolant and 50% water is recom-
mended. Refer to "Maintenance Procedures" in
"Maintaining Your Vehicle" for proper coolant
selection.
Winter Operation
Use of the air Recirculation Mode during winter
months is not recommended because it may
cause window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for about
five minutes in the fresh air and high blower
settings. This will ensure adequate system lu-
brication to minimize the possibility of compres-
sor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be
quickly removed by turning the mode selector
