Daytime Running Lights (DRL) — If Equipped
The headlights on your vehicle will illuminate when the
engine is started and the transmission is in any gear except
PARK. This provides a constantlights oncondition until
the ignition is turned OFF. The lights illuminate at less than
half of normal intensity. If the parking brake is applied, the
Daytime Running Lights (DRL) will turn off. Also, if a turn
signal is activated, the DRL lamp on the same side of the
vehicle may turn off for the duration of the turn signal
activation. Once the turn signal is no longer active, the DRL
lamp will illuminate.
Multifunction Lever
The multifunction lever is located on the left side of the
steering column.
High/Low Beam Switch
Push the multifunction lever toward the instrument panel
to switch the headlights to high beam. Pulling the multi-
function lever back toward the steering wheel will turn the
low beams back on, or shut the high beams off.
Automatic High Beam Headlamp Control — If
Equipped
The Automatic High Beam Headlamp Control system
provides increased forward lighting at night by automat-
ing high beam control through the use of a digital camera
mounted on the inside rearview mirror. This camera de-
tects vehicle specific light and automatically switches from
high beams to low beams until the approaching vehicle is
out of view.

GETTING TO KNOW YOUR VEHICLE 71

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. Refer to
“Uconnect Settings” in “Multimedia” for further infor-
mation.
• 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 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 Activate
1. The Automatic High Beams are enabled through the Uconnect system. Refer to “Uconnect Settings” in “Mul-
timedia” for further information.
2. Turn the headlight switch to the AUTO headlight posi- tion. 3. Push the multifunction lever away from you (toward
front of vehicle) to engage the high beam mode.
NOTE: This system will not activate until the vehicle is at
or above 20 mph (32 km/h).
To Deactivate
1. Pull the multifunction lever toward you (or rearward in vehicle) to manually deactivate the system (normal
operation of low beams).
2. Push back on the multifunction lever to reactivate the system.
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 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
