WINDSHIELD WIPERS AND WASHERS
Windshield Wipers
The wipers and washers are operated by a switch in the
multifunction lever. Turn the end of the lever to select the
desired wiper speed.
Windshield Wiper/Washer Switch

GETTING TO KNOW YOUR VEHICLE 75
Rotate the end of the lever upward, to the first detent past the
intermittent settings for low-speed wiper operation. Rotate
the end of the lever upward to the second detent past the
intermittent settings for high-speed wiper operation.
Intermittent Wiper System
The intermittent feature of this system was designed for use
when weather conditions make a single wiping cycle, with a
variable pause between cycles, desirable. For maximum
delay between cycles, rotate the control knob upward to the
first detent.
The delay interval decreases as you rotate the knob until it
enters the low continual speed position. The delay can be
regulated from a maximum of about 18 seconds between
cycles, to a cycle every one second. The delay intervals will
double in duration when the vehicle speed is 10 mph
(16 km/h) or less.
Windshield Washers
To use the windshield washer, push the washer knob,
located on the end of the multifunction lever, inward to the
second detent. Washer fluid will be sprayed and the wiper
will operate for two to three cycles after the washer knob is
released from this position.If the washer knob is depressed while in the delay range, the
wiper will operate for several seconds after the washer knob
is released. It will then resume the intermittent interval
previously selected. If the washer knob is pushed while in
the off position, the wiper will turn on and cycle approxi
-
mately three times after the wash knob is released.
To prevent freeze-up of your windshield washer system in
cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This rating
information can be found on most washer fluid containers.
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.

Mist Feature
When a single wipe to clear off road mist or spray from a
passing vehicle is needed, push the washer knob, located on
the end of the multifunction lever, inward to the first detent
and release. The wipers will cycle one time and automati-
cally shut off.
NOTE:
The mist feature does not activate the washer pump; there -
fore, no washer fluid will be sprayed on the windshield. The
wash function must be used in order to spray the windshield
with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses moisture on the windshield and automat -
ically activates the wipers for the driver. The feature is espe -
cially useful for road splash or overspray from the
windshield washers of the vehicle ahead. Rotate the end of
the multifunction lever to one of five settings to activate this
feature.
NOTE:
This feature can be programmed through the Uconnect
system. Refer to “Uconnect Settings” in “Multimedia” for
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).

GETTING TO KNOW YOUR VEHICLE 77
•Transmission In NEUTRAL Position — When the igni-
tion is ON, and the transmission is in the NEUTRAL posi -
tion, the Rain Sensing system will not operate until the
wiper switch is moved, vehicle speed is greater than
5 mph (8 km/h), or the gear selector is moved out of the
NEUTRAL position.
• Remote Start Mode Inhibit — On vehicles equipped with
Remote Starting system, Rain Sensing wipers are not oper -
ational when the vehicle is in the remote start mode. Once
the operator is in the vehicle and has placed the ignition
switch in the RUN position, Rain Sensing wiper operation
can resume, if it has been selected, and no other inhibit
conditions (mentioned previously) exist.
CLIMATE CONTROLS
The Climate Control System allows you to regulate the
temperature, air flow, and direction of air circulating
throughout the vehicle. The controls are located on the
touchscreen (if equipped), on the sides of the touchscreen, or
on the instrument panel below the radio.
Climate Controls Without A Touchscreen Overview
The controls for the manual heating and air conditioning
system in this vehicle consist of a series of outer rotary dials
and inner push knobs. These comfort controls can be set to
obtain desired interior conditions.

Manual Climate Control DescriptionsIcon Description
MAX A/C Setting
Rotate the temperature control knob until it is set to MAX A/C. This is the coldest setting and puts the
A/C to maximum power.
A/C Button
Push the A/C button to engage the Air Conditioning (A/C). A LED will illuminate when the A/C
system is engaged.
Recirculation Button
Press and release this button on the touchscreen, or push the button on the faceplate, to change the
system between recirculation mode and outside air mode. Recirculation can be used when outside
conditions, such as smoke, odors, dust, or humidity are present. Recirculation can be used in all
modes except for Defrost. Recirculation may be unavailable if conditions exist that could create
fogging on the inside of the windshield. The A/C can be deselected manually without disturbing the
mode control selection. Continuous use of the Recirculation mode may make the inside air stuffy and
window fogging may occur. Extended use of this mode is not recommended.
Temperature Control
Use this control knob to regulate the temperature of the air inside the passenger compartment.
Rotating the knob counterclockwise, from top center into the blue area of the scale, indicates cooler
temperatures. Rotating the knob clockwise, into the red area, indicates warmer temperatures.
Blower Control
There are seven blower speeds. Use this control knob to regulate the amount of air forced through the
system in any mode you select. The blower speed increases as you move the control clockwise from
the off position.
