GETTING TO KNOW YOUR VEHICLE 65
proper corrosion protection and to protect
against engine overheating. A solution of 50%
OAT (Organic Additive Technology) coolant that
meets the requirements of FCA Material
Standard MS.90032 and 50% water is
recommended Ú page 340.
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 332.
Window Fogging
Interior fogging on the windshield can be quickly
removed by turning the mode selector to
Defrost. The Defrost/Floor mode can be used to
maintain a clear windshield and provide
sufficient heating. If side window fogging
becomes objectionable, increase blower speed
to improve airflow and clearing of the side
windows. Vehicle windows tend to fog on the
inside in mild but rainy or humid weather.
NOTE:
Recirculate without A/C should not be used
for long periods, as fogging may occur.
Automatic Temperature Controls (ATC) will
automatically adjust the climate control
settings 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, 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 Ú page 286.
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.
Windshield Wiper De-Icer — If Equipped
The windshield wiper de-icer is a heating
element located at the base of the windshield.
It operates automatically once the following
conditions are met:
Activation By Front Defrost
The wiper de-icer activates automatically
during a cold weather manual start with full
defrost, and when the ambient temperature
is below 33°F (0.6°C).
Activation By Rear Defrost
The wiper de-icer activates automatically
when the Rear Defrost is operating and the
ambient temperature is below 33°F (0.6°C).
Activation By Remote Start Operation
When the Remote Start is activated and the
outside ambient temperature is less than
33°F (0.6°C) the windshield wiper de-icer is
