It may be helpful to unplug the device during the
cycling process to prevent possible overheating
of the garage door or gate motor.

1. Cycle the ignition to the ON/RUN position.

2. Place the hand-held transmitter 1 to
3 inches (3 to 8 cm) away from the
HomeLink button you wish to program while
keeping the HomeLink indicator light in
view.
3. Continue to press and hold the HomeLink button, while you press and release
(“cycle”) your hand-held transmitter every
two seconds until HomeLink has
successfully accepted the frequency signal.
The indicator light will flash slowly and then
rapidly when fully trained.
4. Watch for the HomeLink indicator to change flash rates. When it changes, it is
programmed. It may take up to 30 seconds
or longer in rare cases. The garage door
may open and close while you are
programming.
5. Press and hold the programmed HomeLink button and observe the indicator light. NOTE:
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the Home
-
Link button is pressed.
To program the two remaining HomeLink
buttons, repeat each step for each remaining
button. DO NOT erase the channels.
If you unplugged the garage door opener/
device for programming, plug it back in at this
time.

EXTERIOR LIGHTS
HEADLIGHT SWITCH
The headlight switch is located on the left side
of the instrument panel. This switch controls the
operation of the headlights, parking lights,
automatic headlights (if equipped), instrument
panel light dimming, cargo light/trailer spotter
lights (if equipped), and fog lights (if equipped).

Headlight Switch

1 — Rotate Headlight Control
2 — Ambient Light Dimmer Control
3 — Instrument Panel Dimmer Control
4 — Push Cargo Light Switch
5 — Push Fog Light Switch

21_DT_OM_EN_USC_t.book Page 52

GETTING TO KNOW YOUR VEHICLE53
To turn on the headlights, rotate the headlight
switch clockwise. When the headlight switch is
on, the parking lights, taillights, license plate
light and instrument panel lights are also turned
on. To turn off the headlights, rotate the
headlight switch back to the O (off) position.
NOTE:
Your vehicle is equipped with plastic head -
light and fog light (if equipped) lenses that
are lighter and less susceptible to stone
breakage than glass lights. Plastic is not as
scratch resistant as glass and therefore
different lens cleaning procedures must be
followed.
To minimize the possibility of scratching the
lenses and reducing light output, avoid
wiping with a dry cloth. To remove road dirt,
wash with a mild soap solution followed by
rinsing.
MULTIFUNCTION LEVER
The multifunction lever is located on the left
side of the steering column.

Multifunction Lever

DAYTIME RUNNING LIGHTS (DRLS)
The Daytime Running Lights (DRLs) come on
whenever the engine is running, and the low
beams are not on. The lights will remain on until
the ignition is placed in the OFF or ACC position,
or the parking brake is engaged.
NOTE:
For vehicles sold in Canada, the Daytime
Running Lights will automatically deactivate
when the front fog lights are turned on.
If a turn signal is activated, the DRL lamp on
the same side of the vehicle will turn off for
the duration of the turn signal activation.
Once the turn signal is no longer active, the
DRL lamp will illuminate.
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
Uconnect system Ú page 237.
HIGH/LOW BEAM SWITCH
Push the multifunction lever toward the
instrument panel to switch the headlights to
high beams. Pulling the multifunction lever
back will turn the low beams on.
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.
CAUTION!
Do not use abrasive cleaning components,
solvents, steel wool or other abrasive
materials to clean the lenses.

The Automatic High Beam Headlamp Control
can be turned on or off by selecting “ON”
under “Auto Dim High Beams” within your
Uconnect Settings Úpage 237, as well as
turning the headlight switch to the AUTO posi -
tion.
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 function improp -
erly.
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), toggle the high beam lever
6 full on/off cycles within 10 seconds of
placing the ignition in the ON position. The
system will return to the default setting upon
placing the ignition in the OFF position.

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 the headlights
on or off according to 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 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.
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

on when the wiper system is on. This feature is
programmable through the Uconnect system
Ú page 237.
If your vehicle is equipped with the Rain Sensing
Wiper system Ú page 59, 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.

21_DT_OM_EN_USC_t.book Page 54

GETTING TO KNOW YOUR VEHICLE55
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.
