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
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.
Automatic Temperature Control (ATC)
Automatic Operation
1. Push the AUTO button on the faceplate, or the AUTObutton on the touchscreen on the Automatic Tempera-
ture Control (ATC) Panel. 2. Next, adjust the temperature that you would like the
system to maintain by adjusting the driver and passen-
ger temperature control buttons. Once the desired tem-
perature is displayed, the system will achieve and
automatically maintain that comfort level.
3. When the system is set up for your comfort level, it is not necessary to change the settings. You will experience
the greatest efficiency by simply allowing the system to
function automatically.
NOTE:
• It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode, and blower speed to provide
comfort as quickly as possible.
• The temperature can be displayed in U.S. or Metric units
by selecting the US/Metric customer-programmable fea-
ture. Refer to the “Uconnect Settings” in “Multimedia”
for further information.
To provide you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan will remain on
low until the engine warms up. The blower will increase in
speed and transition into Auto mode.

Manual Operation Override
This system offers a full complement of manual override
features. The AUTO symbol in the front ATC display will
be turned off when the system is being used in the manual
mode.
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.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, 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
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.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy,
and/or humid weather. To clear the windows, select De-
frost 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.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
• Use care when washing the inside of the rear win-
dow. Do not use abrasive window cleaners on the
interior surface of the window. Use a soft cloth and a

CAUTION!
•Many accessories that can be plugged in draw power
from the vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in long
enough, the vehicle’s battery will discharge suffi-
ciently to degrade battery life and/or prevent the
engine from starting.
• Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will degrade the bat-
tery even more quickly. Only use these intermit-
tently and with greater caution.
• After the use of high power draw accessories, or long
periods of the vehicle not being started (with acces-
sories still plugged in), the vehicle must be driven a
sufficient length of time to allow the alternator to
recharge the vehicle’s battery.
• Power outlets are designed for accessory plugs only.
Do not hang any type of accessory or accessory
bracket from the plug. Improper use of the power
outlet can cause damage.
Wireless Charging Pad — If Equipped
Your vehicle may be equipped with an Open Dots compat-
ible wire-free phone charging surface located in the center
console. The wireless charger features continuous wireless
charging during vehicle operation and allows for uninter-
rupted Bluetooth streaming to properly equipped vehicle
audio systems.
In order to enjoy the convenience of Open Dots wire-free
charging, you must obtain an aftermarket wireless-enabled
case and then install the case on your phone. Set the phone

Instrument Cluster Descriptions
1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000). 2. Instrument Cluster Display
•When the appropriate conditions exist, this display
shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.

3. Speedometer•Indicates vehicle speed.
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. 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 “Servicing And Mainte-
nance.” 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.
NOTE: The hard telltales will illuminate for a bulb check
when the ignition is first cycled.

Engine Oil Life Reset
Oil Change Required
Your vehicle is equipped with an engine oil change indi-
cator system. The “Oil Change Required” message will
display in the instrument cluster display for five seconds
after a single chime has sounded, to indicate the next
scheduled oil change interval. The engine oil change indi-
cator system is duty cycle based, which means the engine
oil change interval may fluctuate, dependent upon your
personal driving style.
Unless reset, this message will continue to display each
time you place the ignition in the ON/RUN position. To
turn off the message temporarily, push and release the OK
or arrow buttons. To reset the oil change indicator system
(after performing the scheduled maintenance), refer to the
following procedure. Vehicles Equipped With Keyless Enter-N-Go — Ignition

2. Push and release the downarrow button to scroll
downward through the main menu to “Vehicle Info.”
3. Push and release the rightarrow button to access the
”Oil Life” screen.
4. Push and hold the OKbutton to reset oil life. If
conditions are met, the gauge and numeric display will
update to show 100%. If conditions are not met a popup
message of To reset oil life engine must be off with
ignition in run will be displayed (for five seconds), and
the user will remain at the Oil Life screen.
5. Push and release the upordown arrow button to exit
the submenu screen.
NOTE: If the indicator message illuminates when you
