Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning sys-
tem. 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.
NOTE:
•For Manual Climate Controls, if the system is in Mix,
Floor or Defrost Mode, the A/C can be turned off, but
the A/C system shall remain active to prevent fogging of
the windows.
• If fog or mist appears on the windshield or side glass,
select Defrost mode, and increase blower speed if
needed.
• If your air conditioning performance seems lower than
expected, check the front of the A/C condenser (located
in front of the radiator), for an accumulation of dirt or
insects. Clean with a gentle water spray from the front of
the radiator and through the condenser.
Recirculation
In cold weather, use of Recirculation mode may lead to
excessive window fogging. The Recirculation feature may
be unavailable (button on the touchscreen greyed out) if
conditions exist that could create fogging on the inside of
the windshield.
On systems with Manual Climate Controls, if equipped,
the Recirculation mode is not allowed in Defrost mode to
improve window clearing operation. Recirculation is dis-
abled automatically if this mode is selected. Attempting to
use Recirculation while in this mode causes the LED in the
control button to blink and then turns off.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
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. OAT
coolant (conforming to MS.90032) is recommended. Refer
to “Fluids and Lubricants” in “Technical Specifications” for
proper coolant selection.

Towing Tips
Before setting out on a trip, practice turning, stopping, and
backing up the trailer in an area located away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent shift-
ing does occur while in DRIVE, use the Electronic Range
Select (ERS) shift control to select a lower gear range.
NOTE:Using a lower gear range while operating the
vehicle under heavy loading conditions will improve per-
formance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
Electronic Range Select (ERS)
• When using the ERS shift control, select the highest gear
that allows for adequate performance and avoids fre-
quent downshifts. For example, choose “5” if the desired
speed can be maintained. Choose “4” or “3” if needed to
maintain the desired speed. •
To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as necessary
to avoid extended driving at high RPM. Return to a
higher gear range or vehicle speed when grade and road
conditions allow.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transmission overheat-
ing, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.

high quality filters should be used to assure most efficient
service. Mopar engine oil filters are high quality oil filters
and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
NOTE:Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable.
WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the ve-
hicle with the air induction system (air cleaner, hoses,
etc.) removed. Failure to do so can result in serious
personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters varies
considerably. Only high quality filters should be used to assure most efficient service. Mopar engine air cleaner
filters are a high quality filter and are recommended.
Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
WARNING!
•
Use only refrigerants and compressor lubricants ap-
proved by the manufacturer for your air conditioning
system. Some unapproved refrigerants are flam-
mable and can explode, injuring you. Other unap-
proved refrigerants or lubricants can cause the sys-
tem to fail, requiring costly repairs. Refer to
Warranty Information Book, for further warranty
information.
• The air conditioning system contains refrigerant un-
der 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.
242 SERVICING AND MAINTENANCE

CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condition-
ing components. Such damage is not covered by the
New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is an ozone-saving product. However,
the manufacturer recommends that air conditioning ser-
vice be performed by authorized dealer or other service
facilities using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system PAG
compressor oil and refrigerants.
Refrigerant Recovery And Recycling — R–1234yf
R–1234yf Air Conditioning Refrigerant is a hydrofluo-
roolefin (HFO) that is endorsed by the Environmental
Protection Agency and is an ozone-friendly substance with
a low global-warming potential. The manufacturer recom-
mends that air conditioning service be performed by an
authorized dealer using recovery and recycling equipment. NOTE:
Use only manufacturer approved A/C system
PAG compressor oil, and refrigerants.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should be
lubricated periodically with a lithium based grease, such as
Mopar Spray White Lube to assure quiet, easy operation
and to protect against rust and wear. Prior to the applica-
tion of any lubricant, the parts concerned should be wiped
clean to remove dust and grit; after lubricating excess oil
and grease should be removed. Particular attention should
also be given to hood latching components to ensure
proper function. When performing other underhood ser-
vices, the hood latch, release mechanism and safety catch
should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as Mopar Lock
Cylinder Lubricant directly into the lock cylinder.

or replacing coolant. Advise your service attendant of this.
As long as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional engine coolant (antifreeze) is needed to
maintain the proper level, only OAT coolant that meets the
requirements of FCA Material Standard MS.90032 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 normally
a result of moisture from rain, snow, or high humidity
accumulating on the radiator and being vaporized when
the thermostat opens, allowing hot engine coolant (anti-
freeze) 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 pro-
tection of your engine which contains aluminum com-
ponents.
• 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 ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
