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 constant "lights on" condition 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 acti -
vation. Once the turn signal is no longer active, the DRL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 instrument panel to
switch the headlights to high beam. Pulling the multifunc -
tion 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. 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 informa -
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 improperly. 2

WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the instru -
ment panel together with a dedicated message and/or
acoustic signal when applicable. These indications are indic -
ative and precautionary and as such must not be considered
as exhaustive. Always refer to 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
— Seat Belt Reminder Warning Light
This warning light indicates when the driver or passenger
seat belt is unbuckled. When the ignition is first placed in the
ON/RUN or ACC/ON/RUN position and if the driver’s
seat belt is unbuckled, a chime will sound and the light will
turn on. When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder Light will
flash or remain on continuously and a chime will sound.
Refer to “Occupant Restraint Systems” in “Safety” for
further information. — 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 either 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

GETTING TO KNOW YOUR INSTRUMENT PANEL 147
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 spec -
ified 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.
— Hood Open Warning Light
This warning light will illuminate when the hood 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. 3
