WINDSHIELD WIPERS AND WASHERS
WINDSHIELD WIPERS
The wipers and washers are operated by a
switch in the multifunction lever, and can only
be operated with the ignition in the ACC or ON/
RUN position. Turn the end of the lever to select
the desired wiper speed.

Windshield Wiper/Washer Switch

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 approximately 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
automatically shut off.
NOTE:
The mist feature does not activate the washer
pump; therefore, 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 automatically activates the wipers for the
driver. The feature is especially 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 on/off through
the Uconnect system. Refer to “Uconnect
Settings” in “Multimedia” for further informa
-
tion.
The sensitivity of the system can be adjusted
with the multifunction 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. Positions 4 and 5
can be used if the driver desires more
sensitivity. 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 perfor -
mance. 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 igni-
tion is first placed in the ON position, 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).
Transmission In NEUTRAL Position — When
the ignition is ON, and the transmission is in
the NEUTRAL position, 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 operational 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 condi -
tions (mentioned previously) exist.

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. The Recirculation indicator and the A/C indicator illuminate when the
Recirculation button is pushed. 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
Temperature Control regulates the temperature of the air forced through the Climate Control system. The temperature
increases as you turn the temperature control knob clockwise. The temperature decreases as you turn the temperature
control knob counterclockwise.
Blower Control
Blower Control regulates the amount of air forced through the Climate Control system. There are seven blower speeds
available. The blower speed increases as you turn the blower control knob clockwise from the lowest blower setting. The
blower speed decreases as you turn the blower control knob counterclockwise.

Mode Control
Turn the Mode Control knob to adjust the airflow distribution. The airflow distribution mode can be adjusted so air comes
from the instrument panel outlets, floor outlets, defrost outlets and demist outlets. The Mode settings are as follows:
Panel Mode Panel Mode
Air comes from the outlets in the instrument panel. Each of these outlets can be individually adjusted to direct the flow of
air. The air vanes of the center outlets and outboard outlets can be moved up and down or side to side to regulate airflow
direction. There is a shut off wheel located below the air vanes to shut off or adjust the amount of airflow from these
outlets.
Bi-Level Mode Bi-Level Mode
Air comes from the instrument panel outlets and floor outlets. A slight amount of air is directed through the defrost and
side window demister outlets.
NOTE:
Bi-Level mode is designed under comfort conditions to provide cooler air out of the panel outlets and warmer air from the
floor outlets.
