2009 HB/HG Aspen/Durango HEV Supplement

As the temperature gets colder it may be necessary to
direct air onto the windshield by using Mix Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. Interior fogging
on the windshield can be quickly removed by selecting
the defrost mode.
Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminants (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminants increase the rate of window fogging.
INSTRUMENT PANEL AND CONTROLS 41
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 is recommended.
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 obstructions.
This will also prevent snow ingestion into the
ducts.
