GETTING TO KNOW YOUR VEHICLE63
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 Úpage 322.
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 Úpage 313.
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 auto
-
matically 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 271.
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 Windshield Wiper De-Icer activates auto -
matically 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 Windshield Wiper De-Icer activates auto -
matically 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 acti-
vated. Exiting Remote Start will resume its
previous operation. If the Windshield Wiper
De-Icer was active, the timer and operation will
continue.
