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 lights, interior lights, and fog
lights (if equipped).

Headlight Switch Headlight Switch (Vehicles Sold In Canada)

NOTE:Vehicles sold in Canada are equipped with a headlight
switch with an AUTO and ON detent but without an OFF
detent. Headlights will be deactivated when the headlight
switch is placed in the parking lights position. However,
the Daytime Running Lights (DRLs) will be activated along
with the front and rear marker lights. The DRLs may be
deactivated when the parking brake is engaged.
Rotate the headlight switch clockwise to the first detent
for parking light and instrument panel light operation.
Rotate the headlight switch to the second detent for
headlight, parking light, and instrument panel light
operation.

lights position to the first detent to turn on headlights,
parking lights, and instrument panel lights. Rotate the
headlight switch to the second detent for the AUTO
position.
DAYTIME RUNNING LIGHTS (DRLS) —
I
F EQUIPPED
The Daytime Running Lights are active when the low
beams are not on, and the engine is running. DRLs may be
deactivated by applying the parking brake.
NOTE:
 For vehicles sold in Canada, the Daytime Running
Lights will automatically deactivate when the front fog
lights are turned on.
 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. The lever will
return to the centered position. To return the headlights to
low beam, pull the lever toward the steering wheel, or
push the lever toward the instrument panel.

Multifunction Lever

AUTOMATIC HIGH BEAM HEADLAMP
C
ONTROL — IF EQUIPPED
The Automatic High Beam Headlamp Control system
provides increased forward lighting at night by
automatically controlling the high beams through the use
of a camera mounted on the vehicle’s header. 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 High
Beam” within your Uconnect Settings
Úpage 184, as
well as turning the headlight switch to the AUTO posi -
tion and placing the multifunction lever in the high
beam 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 obstructions on the windshield or camera
lens will cause the system to function improperly.
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 clockwise to the last detent for
automatic headlight operation. 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. 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.
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 when the driver’s door is opened.

the information in this chapter in the event of a failure
indication. All active telltales will display first if applicable.
The system check menu may appear different based upon
equipment options and current vehicle status. Some
telltales are optional and may not appear.
RED WARNING LIGHTS
Air Bag Warning Light
This warning light will illuminate to indicate a
fault with the air bag, and will turn on for four to
eight seconds as a bulb check when the
ignition is placed in the ON/RUN or ACC/ON/
RUN position. This light will illuminate with a single chime
when a fault with the air bag has been detected, it will stay
on until the fault is cleared. If the light is not on during
startup, stays on, or turns on while driving, have the
system inspected at an authorized dealer as soon as
possible.
Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake light
turns on it may indicate that the parking brake
is applied, that the brake fluid level is low, or that there is
a problem with the Anti-Lock Brake System reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS) / Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake,
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capacity
in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp cornering
maneuvers, which change fluid level conditions. The
vehicle should have service performed, and the brake
fluid level checked.
If brake failure is indicated, immediate repair is necessary.
Vehicles equipped with the Anti-Lock Brake System (ABS)
are also equipped with Electronic Brake Force Distribution
(EBD). In the event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light. Immediate
repair to the ABS system is required.
Operation of the Brake Warning Light can be checked by
turning the ignition switch from the OFF position to the
ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn off
unless the parking brake is applied or a brake fault is
detected. If the light does not illuminate, have the light
inspected by an authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN position.
NOTE:This light shows only that the parking brake is applied. It
does not show the degree of brake application.
Battery Charge Warning Light
This warning light will illuminate when the
battery is not charging properly. If it stays on
while the engine is running, there may be a
malfunction with the charging system. Contact
an authorized dealer as soon as possible.
This indicates a possible problem with the electrical
system or a related component.
Door Open Warning Light
This indicator will illuminate when a door is
ajar/open and not fully closed.
NOTE:If the vehicle is moving, there will also be a single chime.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have failed. It
will take longer to stop the vehicle. You could have a
collision. Have the vehicle checked immediately.

shifts the vehicle into PARK.
The conditions under which AutoPark will engage are
outlined on the following pages.
If the vehicle is not in PARK and the driver turns off the
engine, the vehicle may AutoPark.
AutoPark will engage when all of these conditions are met:

Vehicle is equipped with an 8-speed transmission
 Driver’s door is ajar or if the driver’s door is removed
and the driver is not on the seat (seat pad sensor
detects driver missing)
 Vehicle is not in PARK
 Vehicle speed is 1.2 mph (1.9 km/h) or less
 Ignition is switched from RUN to OFF
NOTE:For Keyless Enter ‘n Go™ equipped vehicles, the engine
will turn off and the ignition switch will change to ACC
position.
If the vehicle is not in PARK and the driver exits the vehicle
with the engine running, the vehicle may AutoPark.
AutoPark will engage when all of these conditions are met:
Vehicle is equipped with an 8-speed transmission
 Driver’s door is ajar or if the driver’s door is removed
and the driver is not on the seat (seat pad sensor
detects driver missing)
 Vehicle is not in PARK
 Vehicle speed is 1.2 mph (1.9 km/h) or less
 Driver’s seat belt is unbuckled
 Brake pedal is not pressed
The message “ AutoPark Engaged Shift To P Then Shift To
Gear ” will display in the instrument cluster.
NOTE:In some cases the ParkSense graphic will be displayed in
the instrument cluster. In these cases, the gear selector
must be returned to “P” to select desired gear.
If the driver shifts into PARK while moving, the vehicle may
AutoPark.
AutoPark will engage ONLY when vehicle speed is 1.2 mph
(1.9 km/h) or less.
The message “ Vehicle Speed Is Too High To Shift To P ” will
be displayed in the instrument cluster if vehicle speed is
above 1.2 mph (1.9 km/h).
WARNING!
 Driver inattention could lead to failure to place the
vehicle in PARK. ALWAYS DO A VISUAL CHECK that
your vehicle is in PARK by verifying that a solid (not
blinking) “P” is indicated in the instrument cluster
display and on the gear selector. If the "P" indicator is
blinking, your vehicle is not in PARK. As an added
precaution, always apply the parking brake when
exiting the vehicle.
 AutoPark is a supplemental feature. It is not
designed to replace the need to shift your vehicle
into PARK. It is a back-up system and should not be
relied upon as the primary method by which the
