further information. The sensitivity of the system can be adjusted with the multi
-
function lever. Wiper delay position 1 is the least sensitive,
and wiper delay position 5 is the most sensitive. Position 3
should be used for normal rain conditions. Positions 1 and 2
can be used if the driver desires less wiper sensitivity. Posi -
tions 4 and 5 can be used if the driver desires more sensi -
tivity. Place the wiper switch in the O (off) position when not
using the system.
NOTE:
• The Rain Sensing feature will not operate when the wiper switch is in the low or high-speed position.
• The Rain Sensing feature may not function properly when ice, or dried salt water is present on the windshield.
• Use of Rain-X or products containing wax or silicone may reduce Rain Sensing performance.
The Rain Sensing system has protection features for the
wiper blades and arms, and will not operate under the
following conditions:
• Low Ambient Temperature — When the ignition is first
turned ON, the Rain Sensing system will not operate until
the wiper switch is moved, vehicle speed is greater than
0 mph (0 km/h), or the outside temperature is greater than
32°F (0°C).

Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning system.
When the air conditioning system is turned on, cool dehu-
midified 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, Flooror 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 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 radi -
ator 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
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 condi -
tions exist that could create fogging on the inside of the
windshield.
On systems with Manual Climate Controls, if equipped, the
Recirculation mode is not allowed in Defrost mode to
improve window clearing operation. Recirculation is
disabled automatically if this mode is selected. Attempting
to use Recirculation while in this mode causes the LED in the
control button to blink and then turns off.

Automatic Temperature Control (ATC)
Automatic Operation
1. Push the AUTO button on the faceplate, or the AUTObutton on the touchscreen on the Automatic Temperature
Control (ATC) Panel.
2. Next, adjust the temperature you would like the system to maintain by adjusting the driver and passenger

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 func -
tion 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
feature. 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.
