Windshield Wiper Operation
Rotate the end of the lever upward to the
second detent past the intermittent settings
for low-speed wiper operation. Rotate the end of the lever upward to the third detent
past the intermittent settings for high-speed
wiper operation.
NOTE:
Do not operate the windshield wipers with
the blades lifted from the windshield.
Intermittent Wiper System
Use the intermittent wiper when weather
conditions make a single wiping cycle, with
a variable pause between cycles, desirable.
Rotate the end of the lever to the first detent
position for one of four intermittent settings.
The delay cycle can be set anywhere between
1 to 18 seconds.
NOTE:
The wiper delay times depend on vehicle
speed. If the vehicle is moving less than
10 mph (16 km/h), delay times will be
doubled.
Windshield Washers
To use the washer, pull the lever toward you
and hold while spray is desired. If the lever
is pulled while in the delay range, the wiper
will start and continue to operate for two or
three wipe cycles after the lever is released.
Then, the intermittent interval previously
selected will resume.
If the lever is pulled while in the off position,
the wipers will operate for two or three wipe
cycles. Then, the wipers will turn off.
CAUTION!
In cold weather, always turn off the wiper
switch and allow the wipers to return to
the park position before turning off the
engine. If the wiper switch is left on and
the wipers freeze to the windshield,
damage to the wiper motor may occur
when the vehicle is restarted.
WARNING!
Sudden loss of visibility through the
windshield could lead to a collision. You
might not see other vehicles or other
obstacles. To avoid sudden icing of the
windshield during freezing weather, warm
the windshield with the defroster before
and during windshield washer use.

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.

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) —
If Equipped
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
adjusting the driver and passenger
temperature 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 tempera-
ture settings for cold or hot vehicles. The
system automatically adjusts the tempera-
ture, 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 U.S./
Metric customer-programmable feature.
Refer to the “Uconnect Settings” in
“Multimedia” in the 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 provide proper corrosion protec -
tion and to protect against engine over -
heating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and
defroster 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
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 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.
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.
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 instruments,
or abrasive window cleaners on the inte-
rior surface of the window.
Keep all objects a safe distance from the
window.
