Owner's Manual

Most of the time, when in Automatic Operation, you can
temporarily put the system into Recirculation Mode by
pressing the Recirculation button. However, under cer-
tain 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 Recircula-
tion Mode, you must first move the Mode knob to Panel,
Mix and then press the Recirculation button. This fea-
ture 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 overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in Section 7 of this
manual 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 lubrication to minimize the possibility
of compressor damage when the system is started again.
