Disabled — Vehicle In Reverse”.
NOTE:
Always adjust the pedals to a position that
allows full pedal travel.
Further small adjustments may be necessary
to find the best possible seat/pedal position.
For vehicles equipped with Driver Memory
Seat, you can use your remote keyless entry
key fob or the memory switch on the driver’s
door trim panel to return the adjustable
pedals to pre-programmed positions. Refer
to “Driver Memory Seat” in “Seats” in this
chapter for further information.
WARNING!

Daytime Running Lights (DRLs)
The headlights on your vehicle will illuminate
when the engine is started and the transmis -
sion is in any gear except PARK. This provides a
constant "lights on" condition until the ignition is
placed in the OFF position. The lights illuminate
at less than half of normal intensity. If the
parking brake is applied, the Daytime Running
Lights (DRLs) 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 Once the turn signal is no
longer active, the DRL lamp will illuminate.
NOTE:
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, refer to “Uconnect Settings”
in “Multimedia” for further information.
High/Low Beam Switch
Push the multifunction lever toward the instru-
ment panel to switch the headlights to high
beam. Pulling the multifunction 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 automating high beam control through
the use of a digital camera mounted on the
inside rearview mirror or forward facing camera.
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 Dim High Beams” within your
Uconnect settings, as well as turning the
headlight switch to the AUTO position. Refer
to “Uconnect Settings” in “Multimedia” 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 windshield or camera
lens will cause the system to function improp -
erly.
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 OFF.
If the windshield or Automatic High Beam Head -
lamp Control mirror is replaced, the mirror must
be re-aimed to ensure proper performance. See
a local authorized dealer.
To Activate

“Uconnect Settings” in “Multimedia” for
further information.

2. Turn the headlight switch to the AUTO head -
light position.

beam) headlights that incorporate dynamic
cornering with 5-degree inboard/15-degree
outboard swivel. The headlights continuously
and automatically adapt to the driving condi -
tions around bends or when cornering based on
steering wheel angle.
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 steering.
The adaptive lights are automatically activated
when the vehicle is traveling above approxi -
mately 5 mph (8 km/h).
Headlights On With Wipers (Available With
