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 adjust 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. 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 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 selected
setting and MAX A/C to exit.
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:
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.

CAUTION!
Interior air enters the Rear Automatic Temperature
Control System through an intake grille, located in the
right side trim panel behind the third row seats. The
heater outlets are located in the right side trim panel,
just behind the sliding door. Do not block or place
objects directly in front of the inlet grille or heater
outlets. The electrical system could overload causing
damage to the blower motor.
Rear Temperature Control
To change the temperature in the rear of the vehicle, push
the temperature buttons. The rear temperature settings are
displayed in the rear ATC panel.
When rear controls are locked by the front system, the Rear
Temperature Lock symbol on the ATC panel is illuminated
and any rear overhead adjustments are ignored.
When the Sync feature is active, the rear temperature is
synchronized to the driver ’s temperature setting. If the rear
temperature is changed, the Sync feature will deactivate.
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. A
solution of 50% OAT (Organic Additive Technology) cool-
ant that meets the requirements of FCA Material Standard
MS.90032 and 50% water is recommended. Refer to “Fluids
and Lubricants” in “Technical Specifications” 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
Before 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 fresh air with the
blower setting on high. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.

3. Temperature Gauge•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for
service if your vehicle overheats. If you decide to look
under the hood yourself, see “Maintaining Your Ve-
hicle”. Follow the warnings under the Cooling System
Pressure Cap paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H”, turn the engine off immediately and call an
authorized dealer for service.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the Keyless Push Button Ignition is in the
ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
5. Instrument Cluster Display
•The instrument cluster display features a driver-
interactive display. Refer to “Instrument Cluster Dis-
play” in “Getting To Know Your Instrument Panel” for
further information.
NOTE: The hard telltales will illuminate for a bulb check
when the ignition is first cycled.

SAFETY TIPS
Transporting Passengers
NEVER TRANSPORT PASSENGERS IN THE CARGO
AREA.
WARNING!
•Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
• It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision, people
riding in these areas are more likely to be seriously
injured or killed.
• Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat belts.
• Be sure everyone in your vehicle is in a seat and
using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can even-
tually poison you. To avoid breathing (CO), follow
these safety tips:
•Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
• If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
• If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling con-
trols to force outside air into the vehicle. Set the
blower at high speed.
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
248 SAFETY

•It is recommended that each track outing should end
with a minimum of one cool down lap using minimal
braking.
• If equipped with a removable lower front fascia grille, it
is recommended to remove it for track use during
warm/hot weather to improve cooling airflow to critical
powertrain and cooling system components.
• All SRT vehicles are track tested for 24 hours of endur-
ance. However, it is recommended that suspension
system, brake system, prop shaft, and ½ shaft boots
should be checked for wear or damage after every track
event.
• Track usage results in increased operating temperatures
of the engine, transmission, clutch – if equipped, drive-
line and brake system. This may affect noise (NVH)
countermeasures designed into your vehicle. New com-
ponents may need to be installed to return the system to
the original NVH performance.
• Tire pressure:
• 40psi (276kpa) hot, recommended 32psi (221kpa) front,
30psi (207 kpa) rear cold NOTE:
It is recommended that you target 40psi (276kpa)
Hot Tire Pressure at the conclusion of each track session.
Starting at 32psi (221kpa) Front and 30psi (207 kpa) Rear
Cold and adjusting based on ambient & track conditions is
recommended. Tire pressure can be monitored via the
instrument cluster display and can assist with adjustments.
Track burnishing your brakes:
To avoid “green lining fade” during track use, the brake
pads and rotors must have a thermal burnish for factory
installed components or when new brake friction compo-
nents are installed:
1. Use one track session to burnish brakes by driving at 75% speed. Brake at approximately 0.60-0.80g max with-
out ABS intervention.
2. Lap the track in this manner until you start smelling the brakes. Continue for another half lap at speed, then do
a two lap cool down with minimal brake applies. Make
sure the brakes are not smoking. If they are, do another
cool down lap.
3. Do not continue for more than one full burnishing lap after you start smelling the brakes. Do not get them
smoking heavily. This will get them too hot and affect
their life negatively in future track use.

STARTING AND OPERATING 279

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
Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the AutoStick shift control to
manually select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions, will improve performance
and extend transmission life by reducing excessive shifting
and heat buildup. This action will also provide better
engine braking.
AutoStick
• When using the AutoStick shift control, select the high-
est gear that allows for adequate performance and
avoids frequent 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 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.
