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 camera mounted on the inside
rearview mirror or a windshield mounted
camera. These cameras detect vehicle specific
light and automatically switch 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

Ú
page 228, as well as turning the headlight
switch to the AUTO position.

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 obstruc -
tions on the windshield or camera lens will
cause the system to function improperly.

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.
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 placed in the OFF
position.
FLASH-TO-PASS
You can signal another vehicle with your
headlights by lightly pulling the multifunction
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 your headlights
on or off based on ambient light levels. To turn
the system on, rotate the headlight switch to the
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 place
the ignition into the OFF position. To turn the
automatic headlights off, turn 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.
DIRECTIONAL LED HEADLAMP
S
YSTEM — IF EQUIPPED

This is a system consisting of LED (low/high
beam) headlights that incorporate dynamic
cornering with 5-degree inboard/15-degree
outboard swivel. The headlights continuously and
automatically adapt to the driving conditions
around bends or when cornering based on
steering wheel angle.

21_DPF_OM_EN_USC_t.book Page 52

GETTING TO KNOW YOUR VEHICLE53
The system directs the headlights to light up the
road in the best way, taking into account the
speed of the vehicle and the bend or corner
angle, as well as the speed of the vehicle while
the steering wheel is being turned.

The adaptive lights are automatically activated
when the vehicle is traveling above approximately
5 mph (8 km/h).

This system can be turned on/off through the
Uconnect Settings under “Steering Directed
Lights” Úpage 228.
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.
AUTOMATIC HEADLIGHTS 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
Ú
page 228. If your vehicle is equipped with the Rain Sensing
Wiper system

Ú
page 58, 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 wipers completely stop.

NOTE:
When your headlights come on during the
daytime, the instrument panel lights will auto -
matically dim to the lower nighttime intensity.
HEADLIGHT DELAY

To assist when exiting the vehicle, the headlight
delay feature will leave the headlights on for up to
90 seconds. This delay is initiated when the ignition
is placed in the OFF position 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
placing the ignition in the ON position.

NOTE:
This feature can be programmed through the
Uconnect system Ú page 228.
The headlight delay feature is automatically
activated if the headlight switch is left in the
AUTO position when the ignition is placed in
the OFF position.
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 and a message will
appear in the instrument cluster display when
the driver’s door is opened.
FRONT FOG LIGHTS — IF EQUIPPED
To activate the front fog lights, turn on the
parking lights or low beam headlights and push
in the center of the headlight switch control
knob. Pushing the headlight switch control knob
a second time will turn the front fog lights off.

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated
Onboard Diagnostic system called OBD II.
This system monitors the performance of the
emissions, engine, and transmission control
systems. When these systems are operating
properly, your vehicle will provide excellent
performance and fuel economy, as well as
engine emissions well within current
government regulations. If any of these systems require service, the OBD
II system will turn on the Malfunction Indicator
Light (MIL). It will also store diagnostic codes
and other information to assist your service
technician in making repairs. Although your
vehicle will usually be drivable and not need
towing, see an authorized dealer for service as
soon as possible.
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have an OBD II and a
connection port to allow access to information
related to the performance of your emissions
controls. Authorized service technicians may
need to access this information to assist with
the diagnosis and service of your vehicle and
emissions system Ú page 220.
CAUTION!
Prolonged driving with the MIL on could
cause further damage to the emission
control system. It could also affect fuel
economy and driveability. The vehicle must
be serviced before any emissions tests can
be performed.
If the MIL is flashing while the vehicle is
running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.
WARNING!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
diagnose, or service your vehicle.
If unauthorized equipment is connected to
the OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could
be impaired or a loss of vehicle control
could occur that may result in an acci -
dent involving serious injury or death.
Access, or allow others to access, infor -
mation stored in your vehicle systems,
including personal information.

TOWING TIPS
Before setting out on a trip, practice turning,
stopping, and backing up the trailer in an area
located away from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include a drive
strategy to avoid frequent shifting when towing.
However, if frequent shifting does occur while in
DRIVE, select TOW/HAUL mode or select a lower
gear range (using the Electronic Range Select
(ERS) shift control). NOTE:
Using TOW/HAUL mode or selecting a lower
gear range (using the ERS shift control) while
operating the vehicle under heavy loading
conditions will improve performance and
extend transmission life by reducing excessive
shifting and heat build-up. This action will also
provide better engine braking.
Six-Speed Automatic Transmission Only
When towing a loaded trailer up steep grades
at low speeds (20 mph [32 km/h] or below),
holding your vehicle in FIRST gear (using the
ERS shift control) can help to avoid
transmission overheating.
If you regularly tow a trailer for more than
45 minutes of continuous operation, then
change the automatic transmission fluid and
filter(s) as specified for "police, taxi, fleet, or
frequent trailer towing." Ú
page 354.
NOTE:
Check the automatic transmission fluid level
before towing (Six-speed automatic only).
