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.

Windshield Wiper/Washer Lever

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 380.
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 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 sili -
cone may reduce Rain Sensing performance.
The Rain Sensing feature can be turned on and
off using the Uconnect system
Ú
page 228.

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.
CLIMATE CONTROLS
The Climate Control system allows you to
regulate the temperature, air flow, and direction
of air circulating throughout the vehicle.
