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. Use of the Air Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage
For information on maintaining the Climate Control
system when the vehicle is being stored for an
extended period of time, see Ú page 302.
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 increase
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 air distribution
box, they could plug the water drains. In Winter
months, make sure the air intake is clear of ice,
slush, and snow.
Cabin Air Filter
The climate control system filters out dust and
pollen from the air. Contact an authorized dealer to
service your cabin air filter, and to have it replaced
when needed.
Stop/Start System — If Equipped
While in an Autostop, the Climate Control system
may automatically adjust airflow to maintain cabin
comfort. Customer settings will be maintained
upon return to an engine running condition.
