Summer Operation
NOTE: In some cases during high temperature opera-
tion, the air conditioning system performance may be
reduced. This is to help protect the engine from overheat-
ing during the high load condition.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use Recir-
culation A/C mode to provide additional comfort while
in automatic mode.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.
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 using the high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the air conditioning system
is started again.
