Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant, during summer, to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50%
concentration is recommended. Refer to Fluids, Lubri-
cants, and Genuine Parts in Section 7 for the proper
coolant type.
When using the air conditioner in extremely heavy
traffic, in hot weather, especially when towing a trailer,
additional engine cooling may be required. If this situa-
tion is encountered, operate the transmission in a lower
gear to increase engine RPM, coolant flow and fan speed.
When stopped in heavy traffic, it may be necessary to shift into NEUTRAL and press the accelerator slightly for
fast idle operation to increase coolant flow and fan speed.
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 partial
Recirculation A/C mode to provide additional comfort.
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
obstructions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
