forming to MS.90032) is recommended. Refer to
“Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure the best possible heater and defroster
performance, make sure the engine cooling
system is functioning properly and the proper
amount, type, and concentration of coolant 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
Before 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
on high. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy and/or humid weather. To clear the
windows, select Defrost or Mix mode and in-
crease the front blower speed. Do not use the
Recirculation mode without A/C for long periods,
as fogging may occur.
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, and if they enter the plenum,
they could plug the water drains. In winter
months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter
The climate control system filters out dust and
pollen from the air. Contact your authorized
dealer to service your A/C air filter, and to have
it replaced when needed.
