NOTE:In cold weather, use of Recirculation mode may
lead to excessive window fogging. The Recirculation fea-
ture 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) — If
Equipped
Automatic Operation
1. Push the AUTO button on the faceplate, or the AUTO button on the touchscreen on the Automatic Tempera-
ture Control (ATC) Panel.
2. Next, adjust the temperature you would like the system to maintain by adjusting the driver and passenger
temperature control buttons. Once the desired tempera-
ture is displayed, the system will achieve and automati-
cally 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
mild washing solution, wiping parallel to the heat-
ing elements. Labels can be peeled off after soaking
with warm water.
• Do not use scrapers, sharp instruments, or abrasive
window cleaners on the interior surface of the win-
dow.
• Keep all objects a safe distance from the window.

2. Reach into the opening beneath the center of the hoodand push the safety latch lever to the left to release it,
before raising the hood.To Close The Hood
Lower the hood to approximately 12 inches (30 cm) from
the engine compartment and drop it. Make sure that the
hood is completely closed.
WARNING!
Be sure the hood is fully latched before driving your
vehicle. If the hood is not fully latched, it could open
when the vehicle is in motion and block your vision.
Failure to follow this warning could result in serious
injury or death.
CAUTION!
To prevent possible damage, do not slam the hood to
close it. Use a firm downward push at the front center
of the hood to ensure that both latches engage.Safety Latch Location

WARNING!
To avoid serious injury or death:
•Only devices designed for use in this type of outlet
should be inserted into any 12 Volt outlet.
• Do not touch with wet hands.
• Close the lid when not in use and while driving the
vehicle.
• If this outlet is mishandled, it may cause an electric
shock and failure.
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.
(Continued)
CAUTION! (Continued)
•Accessories that draw higher power (i.e., coolers,
vacuum cleaners, lights, etc.), will discharge the
battery 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 generator to
recharge the vehicle’s battery.

shows the instrument cluster display messages. Refer
to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.
4. Oil Pressure Gauge •The pointer should always indicate the oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate
a lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
NOTE: In vehicles equipped with Stop/Start, an oil pres-
sure indication of zero is normal during an Autostop. 5. Speedometer
•Indicates vehicle speed.
6. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel door is located.
7. Temperature Gauge

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.
