Winter Operation
To ensure the best possible heater and de-
froster performance, make sure the engine
cooling system is functioning properly and the
proper amount, type, and concentration of cool-
ant is used. Refer to “Maintenance Procedures”
in “Maintaining Your Vehicle” for proper coolant
selection. Use of the air Recirculation mode
during Winter months is not recommended be-
cause 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 conditioning system at idle for about
five minutes in fresh air with the blower setting
in high. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the
glass in mild, rainy and/or humid weather. Win-
dows may frost on the inside of the glass in very
cold weather. To clear the windows, select De-
frost 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
automatically adjust the climate control set-
tings to reduce or eliminate window fogging
on the front windshield. When this occurs,
recirculation will be unavailable.
Outside Air Intake
Make sure the air intake, located directly in front
of the windshield, is free of obstructions such as
leaves. Leaves collected in the air intake may
reduce airflow, can cause odor, and if they enter
the plenum they could plug the water drains. In
winter months, ensure the air intake is clear of
ice, slush and snow.
