A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator
to manually activate or deactivate the air conditioning
system. When the air conditioning system is turned on,
cool dehumidified air will flow through the outlets into
the cabin. For improved fuel economy, press the A/C
button to turn off the air conditioning and manually
adjust the blower and airflow mode settings. Also, make
sure to select only Panel, Bi-Level or Floor modes.

•If fog or mist appears on the windshield or side glass,
select Defrost mode and adjust blower speed if
needed.
• If your air conditioning performance seems lower than
expected, check the front of the A/C condenser (lo-
cated in front of the radiator), for an accumulation of
dirt or insects. Clean with a gentle water spray from
behind the radiator and through the condenser. Fabric
front fascia protectors may reduce airflow to the
condenser, reducing air conditioning performance.
MAX A/C
MAX A/C sets the control for maximum cooling perfor-
mance.
Press and release to toggle between MAX A/C and the
prior settings. The button on the touchscreen illuminates
when MAX A/C is ON. In MAX A/C, the blower level and mode position can be
adjusted to desired user settings. Pressing other settings
will cause the MAX A/C operation to switch to the prior
settings and the MAX A/C indicator will turn off.
Recirculation
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the Recirculation control button. The
recirculation indicator will illuminate when this button is
selected. Press the button a second time to turn off the
Recirculation mode and allow outside air into the vehicle.

NOTE:Each of these features operates independently
from each other. If any feature is controlled manually,
temperature control will continue to operate automati-
cally.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion 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.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

•To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as neces-
sary to avoid extended driving at high RPM. Return to
a higher gear or vehicle speed when grade and road
conditions allow.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions: City Driving
When stopped for short periods, shift the transmission
into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.

If a flush is needed because of component malfunc-
tion, use only the specified fluid for the flushing
procedure.
Engine Oil
Checking Oil Level — 3.6L Engine
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as once a month. The best time to
check the engine oil level is about five minutes after a
fully warmed engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level between the MIN and MAX markings on the dipstick. Adding 1.0 quart (1.0 liter) of oil when the
reading is at the MIN mark will result in a MAX reading
on these engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Checking Oil Level — 5.7L and 6.4L Engine
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the engine oil level is about five minutes after a
fully warmed engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Maintain
the oil level in the “SAFE” range. Adding 1.0 quart (1.0
liter) of oil when the reading is at the bottom of the

WARNING!(Continued)
•The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced technician.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.

542 MAINTAINING YOUR VEHICLE

When additional engine coolant (antifreeze) is needed to
maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
Points To Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
• Do not overfill the coolant expansion bottle.
•
Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze) needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
•
If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion
protection of your engine which contains aluminum
components.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
