EXTERIOR LIGHTS
Headlight Switch
The headlight switch is located on the right
side of the instrument panel. This switch
controls the operation of the headlights,
parking lights, automatic headlights (if
equipped), instrument panel lights, instru-
ment panel light operation, interior lights,
fog lights (if equipped), and headlight
leveling (if equipped). Headlight Switch
Rotate the headlight switch clockwise to the
first detent for parking light and instrument
panel light operation. Rotate the headlight
switch to the second detent for headlight,
parking light, and instrument panel light
operation.
Daytime Running Lights — If Equipped
The Daytime Running Lights (DRLs) are in a
dedicated position below the headlight
assembly. DRLs are active when the Low Beams are not and when the vehicle is
shifted into any position other than PARK.

Persons who are unable to feel pain to
the skin because of advanced age,
chronic illness, diabetes, spinal cord
injury, medication, alcohol use, exhaus-
tion, or other physical conditions must
exercise care when using the steering
wheel heater. It may cause burns even at
low temperatures, especially if used for
long periods.

wheel that insulates against heat, such
as a blanket or steering wheel covers of
any type and material. This may cause
the steering wheel heater to overheat.1 — Instrument Panel Dimmer Control

Automatic High Beam — 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 vehicle’s header. 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 High Beam” within your
Uconnect settings, as well as turning the
headlight switch to the AUTO position and
placing the multifunction lever in the high
beam position. Refer to “Uconnect Settings”
in “Multimedia” in the Owner’s Manual 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 wind-
shield or camera lens will cause the
system to function improperly.
Flash-To-Pass
You can signal another vehicle with your
headlights by lightly pulling the multifunc -
tion lever toward you. This will cause the
high beam headlights to turn on, and remain
on, until the lever is released.
Automatic Headlights — If Equipped
This system automatically turns the head -
lights on or off according to ambient light
levels. To turn the system on, rotate the
headlight switch clockwise to the last detent
for automatic headlight operation. When the
system is on, the headlight time delay
feature is also on. This means the headlights
will stay on for up to 90 seconds after you
place the ignition into the OFF position. To
turn the automatic system off, move the
headlight switch out of the AUTO position.
NOTE:
The engine must be running before the head -
lights will come on in the automatic mode.
Front And Rear Fog Lights — If Equipped
The fog light switches are built into the head -
light switch. Fog Light Switch Location
To activate the front fog lights, push the
upper half of the headlight switch. To turn
off the front fog lights, push the upper half
of the headlight switch a second time.
To activate the rear fog lights, push the lower
half of the headlight switch. To turn off the
rear fog lights, push the lower half of the
headlight switch a second time.
NOTE:
To turn on the rear fog lamps, the low beam
lamps or front fog lamps must first be active.

An indicator light in the instrument cluster
illuminates when the fog lights are turned on.

Turn Signals
Move the multifunction lever up or down and
the arrows on each side of the instrument
cluster flash to show proper operation of the
front and rear turn signal lights.
NOTE:
If either light remains on and does not flash,
or there is a very fast flash rate, check for a
defective outside light bulb. If an indicator
fails to light when the lever is moved, it
would suggest that the indicator bulb is
defective.
Lights-On Reminder
If the headlights, parking lights, or cargo
lights are left on after the ignition is placed
in the OFF position, a chime will sound when
the driver’s door is opened.
Headlight Leveling System — If Equipped

Your vehicle may be equipped with a headlight
leveling system. This system allows the driver
to maintain proper headlight beam position
with the road surface regardless of vehicle load.
The control switch is located on the instrument
panel next to the dimmer control.
Headlight Leveling Control
To operate, rotate the control switch until the
appropriate number, which corresponds to
the load listed on the chart, aligns with the
indicator line on the switch.
0 /1 Driver only, or driver and front passenger.

WINDSHIELD WIPERS AND
WASHERS

The windshield wiper/washer control lever is
located on the right side of the steering column.
The front wipers are operated by rotating a
switch, located at the end of the lever.

Refer to “Rear Window Wiper/Washer” in
this section for further information on using
the rear window wiper/washer.Windshield Wiper/Washer Lever
Windshield Wiper Operation
Rotate the end of the lever upward to the
second detent past the intermittent settings
for low-speed wiper operation. Rotate the end of the lever upward to the third detent
past the intermittent settings for high-speed
wiper operation.
NOTE:
Do not operate the windshield wipers with
the blades lifted from the windshield.
Intermittent Wiper System
Use the intermittent wiper when weather
conditions make a single wiping cycle, with
a variable pause between cycles, desirable.
Rotate the end of the lever to the first detent
position for one of four intermittent settings.
The delay cycle can be set anywhere between
1 to 18 seconds.
NOTE:
The wiper delay times depend on vehicle
speed. If the vehicle is moving less than
10 mph (16 km/h), delay times will be
doubled.
Windshield Washers
To use the washer, pull the lever toward you
and hold while spray is desired. If the lever
is pulled while in the delay range, the wiper
will start and continue to operate for two or
three wipe cycles after the lever is released.
Then, the intermittent interval previously
selected will resume.
If the lever is pulled while in the off position,
the wipers will operate for two or three wipe
cycles. Then, the wipers will turn off.
CAUTION!
In cold weather, always turn off the wiper
switch and allow the wipers to return to
the park position before turning off the
engine. If the wiper switch is left on and
the wipers freeze to the windshield,
damage to the wiper motor may occur
when the vehicle is restarted.
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.

Mist Feature
Push upward on the wiper lever to activate a
single wipe to clear off road mist or spray
from a passing vehicle. As long as the lever
is held up, the wipers will continue to
operate.
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.
Rear Window Wiper/Washer — If Equipped
A rotary switch on the center portion of the
windshield wiper/washer lever controls the
operation of the rear wiper/washer function.Rear Wiper/Washer Control
Rotate the switch upward to the first detent
position for intermittent operation and to the
second detent for continuous rear wiper
operation. Push the wiper lever toward the instrument
panel to activate the rear washer. The washer
pump and wiper will continue to operate as
long as the lever is held.
If the rear wiper is operating when the igni
-
tion is placed in the OFF position, the wiper
will automatically return to the “park” posi -
tion. When the vehicle is restarted, the wiper
will resume function at whichever position
the switch is set at.
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.
