On some vehicles, the Daytime Running Lights
may deactivate, or reduce intensity, on one side
of the vehicle (when a turn signal is activated on
that side), or on both sides of the vehicle (when
the hazard warning lights are activated).
HIGH/LOW BEAM SWITCH
Push the multifunction lever toward the instrument
panel to switch the headlights to high beams.
Pulling the multifunction back toward the steering
wheel will turn the low beams back on, or shut the
high beams off.
AUTOMATIC HIGH BEAMS —
I
F EQUIPPED
The Automatic High Beam Headlight system
provides increased forward lighting at night by
automating high beam control through the use of a
digital camera mounted on the inside rearview
mirror. 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 Headlight system can
be turned on or off by selecting or deselecting
“Auto Dim High Beams” within Uconnect
Settings Ú page 204.
The headlight switch must also be turned to the
AUTO position after Automatic High Beams is
enabled within Uconnect Settings for the
feature to activate.
Automatic High Beams will only activate when
the vehicle speed is above 22 mph (35 km/h).
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
Headlight Control mirror is replaced, the mirror
must be re-aimed to ensure proper performance.
See a local authorized dealer.
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
This system automatically turns the headlights on
or off according to ambient light levels. To turn the
system on, rotate the headlight switch
counterclockwise to the AUTO position. 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. The headlight time delay can be
programmed to 0/30/60/90 seconds within the
Uconnect system Ú
page 204.
To turn the automatic system off, move the
headlight switch out of the AUTO position.
NOTE:The engine must be running before the headlights
will come 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.
NOTE:Vehicles sold in Canada are equipped with a head -
light switch with an AUTO and ON detent but
