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 of engine coolant to distilled water is
recommended. Refer to “Cooling System” under “Main-
tenance Procedures” in Section 7.
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 and set the air conditioner to recirculation mode.
Operating the air conditioner in recirculation mode pro-
vides the maximum performance from your air condi-
tioning. When stopped in heavy traffic, it may be neces-
sary to shift into NEUTRAL and depress the accelerator
slightly for fast idle operation.
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. This will help prevent snow going into the ducts.
