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 must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended. Refer
to “Maintenance Procedures” in “Maintaining Your Ve-
hicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Refer to “Maintenance Procedure” in
“Maintaining Your Vehicle” for proper coolant selection.
Use of the air Recirculation mode during Winter months is
not recommended because it may cause window fogging.
Vacation/Storage
Any time 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 fresh air
with the blower setting on high. This will ensure adequate
system lubrication to minimize the possibility of compres-
sor damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost on
the inside of the glass in very cold weather. To clear the
windows, select Defrost or Mix mode and increase the
front blower speed. Do not use the Recirculation mode
without A/C for long periods, as fogging may occur.
NOTE:
Automatic Temperature Controls (ATC) will auto-
matically adjust the climate control settings to reduce or
eliminate window fogging on the front windshield. When
this occurs, recirculation will be unavailable.
