Summer Operation
The engine cooling system must be protected with
a high-quality antifreeze coolant to provide 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 265.
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.

GETTING TO KNOW YOUR VEHICLE
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 256.
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 plenum, 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.
