WARNING!
heater. It may cause burns even at low
temperatures, especially if used for long
periods of time.
• Do not place anything on the seat or
seatback that insulates against heat,
such as a blanket or cushion. This may
cause the seat heater to overheat. Sit-
ting in a seat that has been overheated
could cause serious burns due to the
increased surface temperature of the
seat.
Rear Heated Seats — If Equipped
On some models, the two rear outboard seats
may be equipped with heated seats. There
are two heated seat switches that allow the
rear passengers to operate the seats indepen-
dently. The heated seat switches for each
heater are located on the rear of the center
console.
You can choose from HI, LO, or OFF heat
settings. Amber indicator lights in each
switch indicate the level of heat in use. Two
indicator lights will illuminate for HI, one for
LO and none for OFF.• Push the switch
once to turn the HI
setting on.
• Push the switch
a second time to turn
the LO setting on.
• Push the switch
a third time to turn the
heating elements off.
The level of heat selected will stay on until
the operator changes it.
WARNING!
•Persons who are unable to feel pain to the
skin because of advanced age, chronic ill-
ness, diabetes, spinal cord injury, medica-
tion, alcohol use, exhaustion or other
physical condition must exercise care
when using the seat heater. It may cause
burns even at low temperatures, especially
if used for long periods of time.
•Do not place anything on the seat or seat-
back that insulates against heat, such as a
blanket or cushion. This may cause the
seat heater to overheat. Sitting in a seat
that has been overheated could cause se-
rious burns due to the increased surface
temperature of the seat.
Front Ventilated Seats
If your vehicle is equipped with ventilated
seats, the seat cushion and seat back will
have fans that draw the air from the passen-
ger compartment and move air through fine
perforations in the seat cover to help keep the
driver and front passenger cooler in higher
ambient temperatures. The fans operate at
two speeds, HI and LO.
The front ventilated seats control buttons are
located within the Uconnect system. You can
gain access to the control buttons through
the climate screen or the controls screen.
• Press the ventilated seat button
once
to choose HI.
• Press the ventilated seat button
a
second time to choose LO.
• Press the ventilated seat button
a third
time to turn the ventilated seat off.
NOTE:
The engine must be running for the ventilated
seats to operate.

The Rain Sensing system has protection fea-
tures for the wiper blades and arms, and will
not operate under the following conditions:
•Low Ambient Temperature— When the igni-
tion is first turned ON, the Rain Sensing
system will not operate until the wiper
switch is moved, vehicle speed is greater
than 3 mph (5 km/h), or the outside tem-
perature is greater than 32°F (0°C).
•Transmission In NEUTRAL Position— When
the ignition is ON, and the automatic trans-
mission is in the NEUTRAL position, the
Rain Sensing system will not operate until
the wiper switch is moved, vehicle speed is
greater than 3 mph (5 km/h), or the gear
selector is moved out of the NEUTRAL
position.
Rear Window Wiper/Washer
The rear wiper/washer controls are located on
the multifunction lever on the left side of the
steering column. The rear wiper/washer is
operated by rotating a switch, located at the
middle of the lever.Rotate the center portion of the lever upward
to the first detent for intermittent operation
and to the second detent for continuous rear
wiper operation.
Rotating the center portion upward once
more will activate the washer pump which
will continue to operate as long as the switch
is held. Upon release of the switch, the wip-
ers will resume the continuous rear wiper
operation. When this rotary control is in the
OFF position, rotating it downward will acti-
vate the rear washer pump which will con-
tinue to operate as long as the switch is held.
Once the switch is released it will return to
the OFF position and the wipers will cycle
several times before returning to the parked
position.
NOTE:
As a protective measure, the pump will stop if
the switch is held for more than 20 seconds.
Once the switch is released the pump will
resume normal operation.
If the rear wiper is operating when the igni-
tion is turned OFF, the wiper will automati-
cally return to the “park” position.
CLIMATE CONTROLS
The Climate Control System allows you to
regulate the temperature, air flow, and direc-
tion of air circulating throughout the vehicle.
The controls are located on the touchscreen
(if equipped) and on the instrument panel
below the radio.

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 in-
crease blower speed if needed.•I
f your air conditioning performance seems
lower than expected, check the front of the
A/C condenser (located in front of the radia-
tor), 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 cool-
ing performance.

tion can be adjusted to desired user settings.
Pressing other settings will cause the MAX
A/C operation to switch to the selected set-
ting 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 AUTO button on the touchscreen on
the Automatic Temperature Control (ATC)
Panel.
2. Next, adjust the temperature that you
would like the system to maintain by ad-
justing the driver and passenger tempera-
ture control buttons. Once the desired
temperature 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.
GETTING TO KNOW YOUR VEHICLE
50

• The temperature can be displayed in U.S.
or Metric units by selecting the US/Metric
customer-programmable feature. Refer to
the “Uconnect Settings” in “Multimedia”
in your Owner’s Manual 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
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to pro-
vide proper corrosion protection and to pro-
tect against engine overheating. OAT coolant
(conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and de-
froster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentration
of coolant is used. Use of the Air Recircula-
tion mode during Winter months is not rec-
ommended, 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 ad-
equate system lubrication to minimize the
possibility of compressor damage 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 Defrost 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 window. 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 heating elements. Labels can be
peeled off after soaking with warm
water.
• Do not use scrapers, sharp instru-
ments, or abrasive window cleaners on
the interior surface of the window.
• Keep all objects a safe distance from
the window.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstruc-
tions, such as leaves. Leaves collected in the
air intake may reduce airflow, and if they
enter the plenum, they could plug the water
drains. In Winter months, make sure the air
intake is clear of ice, slush, and snow.
