When the system is on, the Headlight Delay
feature is also on. This means the headlights
will stay on for up to 90 seconds after you
turn the ignition switch to the OFF position.
To turn the automatic headlights off, turn the
headlight switch out of the A (auto) position.
NOTE:
The engine must be running before the head-
lights will turn on in the Automatic Mode.
Parking Lights And Panel Lights
To turn on the parking lights and instrument
panel lights, rotate the headlight switch
clockwise. To turn off the parking lights,
rotate the headlight switch back to the O (off)
position.
Headlights On Automatically With
Wipers
If your vehicle is equipped with Automatic
Headlights, it also has this customer-
programmable feature. When your headlights
are in the automatic mode and the engine is
running, they will automatically turn on when
the wiper system is on. This feature is pro-grammable through the Uconnect system
screen. Refer to “Uconnect Settings” in
“Multimedia” in the Owner’s Manual for fur-
ther information.
If your vehicle is equipped with a “Rain
Sensitive Wiper System” and it is activated,
the headlights will automatically turn on after
the wipers complete five wipe cycles within
approximately one minute, and they will turn
off approximately four minutes after the wip-
ers completely stop.
Refer to “Windshield Wipers And Washers” in
“Getting To Know Your Vehicle” for further
information.
NOTE:
When your headlights come on during the
daytime, the instrument panel lights will au-
tomatically dim to the lower nighttime inten-
sity.Adaptive Bi-Xenon High Intensity
Discharge Headlights — If Equipped
This system automatically swivels the head-
light beam pattern horizontally to provide
increased illumination in the direction the
vehicle is steering.NOTE:
• Each time the Adaptive Headlight System
is turned on, the headlights will initialize by
performing a brief sequence of rotations.
• The Adaptive Headlight System is active
only when the vehicle is moving forward.
The Adaptive Headlight System can be
turned on or off using the Uconnect System,
refer to “Uconnect Settings” in “Multime-
dia” in the Owner’s Manual for further infor-
mation.
Headlight Delay
To aid in your exit, your vehicle is equipped
with a headlight delay that will leave the
headlights on for approximately up to 90 sec-
onds. This delay is initiated when the ignition
is turned OFF while the headlight switch is
on, and then the headlight switch is cycled
off. Headlight delay can be cancelled by
either turning the headlight switch on then
off, or by turning the ignition ON.
39

NOTE:
Battery saver mode is canceled if the ignition
is ON.
If the headlights remain on while the ignition
is cycled OFF, the exterior lights will auto-
matically turn off after eight minutes. If the
headlights are turned on and left on for eight
minutes while the ignition is OFF, the exterior
lights will automatically turn off.
NOTE:
The battery saver mode is canceled if the
ignition is OFF and the headlamp switch is in
the park lamp position. The parking lamps
will remain on and drain the vehicle's battery.
WINDSHIELD WIPERS AND
WASHERS
The windshield wiper/washer controls are lo-
cated 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. For information on the
rear wiper/washer, refer to “Rear Window
Wiper/Washer” in this section.
Windshield Wiper Operation
Rotate the end of the lever to one of the first
four detent positions for intermittent set-
tings, the fifth detent for low wiper operation
and the sixth detent for high wiper operation.
CAUTION!
Always remove any buildup of snow that
prevents the windshield wiper blades from
returning to the “park” position. If the
windshield wiper switch is turned off, and
the blades cannot return to the “park”
position, damage to the wiper motor may
occur.
Intermittent Wiper System
Use one of the four intermittent wiper set-
tings when weather conditions make a single
wiping cycle, with a variable delay between
cycles, desirable. At driving speeds above
10 mph (16 km/h), the delay can be regu-
lated from a maximum of approximately
18 seconds between cycles (first detent), to a
cycle every one second (fourth detent).
NOTE:
If the vehicle is moving less than 10 mph
(16 km/h), delay times will be doubled.
Windshield Washer Operation
To use the washer, push on the end of the
lever (toward the steering wheel) and hold
while spray is desired. If the lever is pushed
while in the intermittent setting, the wipers
will turn on and operate for several wipe
cycles after the end of the lever is released,
and then resume the intermittent interval
previously selected.
If the end of the lever is pushed while the
wipers are in the off position, the wipers will
operate for several wipe cycles, then turn off.
Multifunction Lever
41

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.
WARNING!
Sudden loss of visibility through the wind-
shield 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 wind-
shield with the defroster before and during
windshield washer use.
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 products containing wax or silicone
may reduce Rain Sensing performance.
• The Rain Sensing feature can be turned on
and off using the Uconnect System, refer to
“Uconnect Settings” in “Multimedia” in
the Owner’s Manual for further information.
GETTING TO KNOW YOUR VEHICLE

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.
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.
CLIMATE CONTROLS
The Climate Control System allows you to
regulate the temperature, air flow, and direc-
tion of air circulating throughout the vehicle.
The controls are located on the touchscreen
(if equipped) and on the instrument panel
below the radio.
43

NOTE:
ERM is disabled anytime the ESC is in “Full
Off” mode (if equipped). Refer to “Electronic
Stability Control (ESC)” in this section for a
complete explanation of the available ESC
modes.
WARNING!
Many factors, such as vehicle loading,
road conditions and driving conditions,
influence the chance that wheel lift or
rollover may occur. ERM cannot prevent all
wheel lift or roll overs, especially those
that involve leaving the roadway or striking
objects or other vehicles. The capabilities
of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous
manner which could jeopardize the user's
safety or the safety of others.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize
an excessively swaying trailer and will take
the appropriate actions to attempt to stop the
sway. TSC will become active automatically
once an excessively swaying trailer is recog-
nized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in “Starting
And Operating” for further information.
When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will
flash, the engine power may be reduced and
you may feel the brakes being applied to
individual wheels to attempt to stop the
trailer from swaying. TSC is disabled when
the ESC system is in the “Partial Off” or “Full
Off” modes.WARNING!
If TSC activates while driving, slow the
vehicle down, stop at the nearest safe
location, and adjust the trailer load to
eliminate trailer sway.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time
required to reach full braking during emer-
gency braking situations. It anticipates when
an emergency braking situation may occur by
monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake
system for a panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.

Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’s instructions. Use of safety chains is
mandatory. Attach a tow bar or other towing
device to main structural members of the
vehicle, not to bumpers or associated brack-
ets. State and local laws regarding vehicles
under tow must be observed.
If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN mode, not the ACC
mode.If the vehicle's battery is discharged, refer to
“Manual Park Release” in this section for
instructions on shifting the transmission out
of PARK for towing.
CAUTION!
• Do not use sling type equipment when
towing. Vehicle damage may occur.
• When securing the vehicle to a flat bed
truck, do not attach to front or rear
suspension components. Damage to
your vehicle may result from improper
towing.
CAUTION!
• If the vehicle being towed requires steer-
ing, the ignition switch must be in the
ACC or ON/RUN mode, not in the LOCK/
OFF mode.
NOTE:
SRT vehicles and 4WD models without 4WD
LOW range should only be towed with all four
wheelsOFFthe ground.

Windshield Wiper Blades
Clean the rubber edges of the wiper blades
and the windshield periodically with a sponge
or soft cloth and a mild nonabrasive cleaner.
This will remove accumulations of salt or road
film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield.
Avoid using the wiper blades to remove frost
or ice from the windshield. Keep the blade
rubber out of contact with petroleum prod-
ucts such as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines or
wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary.The wiper blades and wiper arms should be
inspected periodically, not just when wiper
performance problems are experienced. This
inspection should include the following
points:
• Wear or uneven edges
• Foreign material
• Hardening or cracking
• Deformation or fatigue
If a wiper blade or wiper arm is damaged,
replace the affected wiper arm or blade with
a new unit. Do not attempt to repair a wiper
arm or blade that is damaged.
