Mist
Use the Mist feature when weather condi-
tions make occasional usage of the wipers
necessary. Rotate the end of the lever down-
ward to the MIST position and release for a
single wiping cycle.
NOTE:
The Mist feature does not activate the washer
pump; therefore, no washer fluid will be
sprayed on the windshield. The wash func-
tion must be used in order to spray the
windshield with washer fluid.
Rain Sensing Wipers — If Equipped
This feature senses rain or snowfall 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 four settings to activate this feature.
The sensitivity of the system can be adjusted
with the multifunction lever. Wiper delay po-
sition one is the least sensitive, and wiper
delay position four is the most sensitive.NOTE:
Wiper delay position three should be used for
normal rain conditions.
Settings one and two can be used if the driver
desires less wiper sensitivity. Setting four can
be used if the driver desires more sensitivity.
Place the wiper switch in the 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 feature can be turned on
and off using the Uconnect System, refer to
“Uconnect Settings” in “Multimedia” in
the Owners Manual for further information.
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.
39

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.HEADLIGHT WASHERS
The multifunction lever operates the head-
light washers when the ignition switch is in
the ON position and the headlights are
turned on. The multifunction lever is located
on the left side of the steering column.
To use the headlight washers, push the mul-
tifunction lever inward (toward the steering
column) and release it. The headlight wash-
ers will spray a timed high-pressure spray of
washer fluid onto each headlight lens. In
addition, the windshield washers will spray
the windshield and the windshield wipers will
cycle.
NOTE:
After turning the ignition switch and head-
lights ON, the headlight washers will operate
on the first spray of the windshield washer
and then every eleventh spray after that.

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
CAUTION!
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.
Cabin Air Filter
The climate control system filters out dust
and pollen from the air. Contact an autho-
rized dealer to service your cabin air filter,
and to have it replaced when needed.
