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 through the
Uconnect system. Refer to “Uconnect Settings”
in “Multimedia” for further information.
The sensitivity of the system can be adjusted
with the multifunction lever. Wiper delay posi -
tion 1 is the least sensitive, and wiper delay
position 5 is the most sensitive. Position 3
should be used for normal rain conditions. Posi -
tions 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.
CLIMATE CONTROLS
The Climate Control system allows you to regu -
late the temperature, air flow, and direction of
air circulating throughout the vehicle. The
