Automatic Headlights — If Equipped
This system automatically turns the headlights on or off
according to ambient light levels. To turn the system on,
rotate the headlight switch to the A (auto) position.
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 headlights
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 programmable through the
Uconnect system screen. Refer to “Uconnect Settings” in
“Multimedia” for further information.
If your vehicle is equipped with a “Rain Sensitive Wiper
System” and it is activated, the headlights will automati-
cally turn on after the wipers complete five wipe cycles
within approximately one minute, and they will turn off
approximately four minutes after the wipers 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 day-
time, the instrument panel lights will automatically dim to
the lower nighttime intensity.
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 seconds. 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.

Dimmer Controls
The brightness of the instrument panel lighting can be
regulated by rotating the dimmer control up (brighter) or
down (dimmer). When the headlights are on you can
supplement the brightness of the instrument cluster dis-
play, radio and overhead console by rotating the control to
its farthest position up until you hear a click. This feature
is termed the “Parade” mode and is useful when head-
lights are required during the day.
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. For information on the rear
wiper/washer, refer to “Rear Window Wiper/Washer” in
this section.

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.

HEADLIGHT WASHERS — IF EQUIPPED
The multifunction lever operates the headlight washers
when the ignition switch is in the ON position and the
headlights are turned on. The multifunction lever is located
on the left side of the steering column.
To use the headlight washers, push the multifunction lever
inward (toward the steering column) and release it. The
headlight washers will spray a timed high-pressure spray
of washer fluid onto each headlight lens. In addition, the
windshield washers will spray the windshield and the
windshield wipers will cycle.
NOTE:After turning the ignition switch and headlights
ON, the headlight washers will operate on the first spray of
the windshield washer and then every eleventh spray after
that.
CLIMATE CONTROLS
The Climate Control System allows you to regulate the
temperature, air flow, and direction of air circulating
throughout the vehicle. The controls are located on the
touchscreen (if equipped) and on the instrument panel
below the radio.

The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as Mopar Lock
Cylinder Lubricant directly into the lock cylinder.
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 products such as engine oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor perfor-
mance 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 follow-
ing 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.
Front Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back against the
glass without the wiper blade in place or the glass may
be damaged.
