DAYTIME RUNNING LIGHTS (DRLS) — IF
E
QUIPPED
The headlights on your vehicle will illuminate
when the engine is started and the
transmission is in any gear except PARK. This
provides a constant "lights on" condition until
the ignition is placed in the OFF position. The
lights illuminate at less than half of normal
intensity. If the parking brake is applied, the
Daytime Running Lights (DRLs) will turn off.
Also, if a turn signal is activated, the DRL lamp
on the same side of the vehicle may turn off for
the duration of the turn signal activation. Once
the turn signal is no longer active, the DRL lamp
will illuminate.
NOTE:
If allowed by law in the country in which the
vehicle was purchased, the Daytime Running
Lights can be turned on and off using the Ucon -
nect system, refer to “Uconnect Settings” in
“Multimedia” for further information.
HIGH/LOW BEAM SWITCH
Push the multifunction lever toward the
instrument panel to switch the headlights to
high beam. Pulling the multifunction lever back
toward the steering wheel will turn the low
beams back on, or shut the high beams off.
AUTOMATIC HIGH BEAM HEADLAMP
C
ONTROL — IF EQUIPPED

The Automatic High Beam Headlamp Control
system provides increased forward lighting at
night by automating high beam control through
the use of a digital camera mounted on the inside
rearview mirror or forward facing camera. This
camera detects vehicle specific light and
automatically switches from high beams to low
beams until the approaching vehicle is out of view.

NOTE:
The Automatic High Beam Headlamp Control
can be turned on or off by selecting “ON”
under “Auto Dim High Beams” within your
Uconnect settings, as well as turning the
headlight switch to the AUTO position. Refer
to “Uconnect Settings” in “Multimedia” for
further information.

Broken, muddy, or obstructed headlights
and taillights of vehicles in the field of view
will cause headlights to remain on longer
(closer to the vehicle). Also, dirt, film, and
other obstructions on the windshield or
camera lens will cause the system to func -
tion improperly.

To opt out of the Advanced Auto High Beam
Sensitivity Control (default) and enter
Reduced High Beam Sensitivity Control (not
recommended), on vehicles equipped with
mirror controlled automatic high beams and
without the forward facing camera, toggle the
high beam lever six full on/off cycles within
10 seconds of placing the ignition in the ON
position. The system will return to the default
setting when the ignition is OFF.
If the windshield or Automatic High Beam
Headlamp Control mirror is replaced, the mirror
must be re-aimed to ensure proper
performance. See a local authorized dealer.

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.

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.
