WINDSHIELD WIPERS AND WASHERS
The windshield wiper/washer controls are located
on the multifunction lever on the left side of the
steering column. The front wipers are operated by
rotating a switch, located on the end of the lever.

Windshield Wiper/Washer Lever

WINDSHIELD WIPER OPERATION
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 Wipers
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.
Mist
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.
For information on wiper care and replacement,
see Ú
page 351.
1 — Push End Inward (Hold For Washer Or Short
Press For Mist)
2 — Rotate For Front Wiper Operation
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.

RAIN SENSING WIPERS — IF EQUIPPED
This feature senses rain or snowfall on the
windshield and automatically activates the wipers.
Rotate the end of the multifunction lever to one of
five detent positions to activate this feature.
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 posi -
tion.
The Rain Sensing feature may not function prop -
erly when ice, or dried salt water is present on
the windshield.
Use of Rain-X or products containing wax or sili-
cone may reduce Rain Sensing performance.
The Rain Sensing feature can be turned on and
off using the Uconnect system Ú page 191.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 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 the Remote Start 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

suggested control settings for various weather
conditions.
Summer Operation
The engine cooling system must be protected with
a high-quality antifreeze coolant to provide proper
corrosion protection and to protect against engine
overheating. 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 Recirculation mode during
Winter months is not recommended, because it
may cause window fogging.
Vacation/Storage

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 obstructions, 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 authorized dealer to
