Daytime Running Lights
Non-SRT Vehicles
The Daytime Running Lights (low intensity)
come on whenever the engine is running, and
the transmission is not in the PARK position.
The lights will remain on until the ignition is
switched to the OFF or ACC position or the
parking brake is engaged.
NOTE:
• If a turn signal is activated, the DRL lamp
on the same side of the vehicle will turn off
for the duration of the turn signal activa-
tion. Once the turn signal is no longer
active, the DRL lamp will illuminate.
• The DRL function may be disabled through
the Uconnect system. Refer to “Uconnect
Settings” in “Multimedia” in the Owner’s
Manual for further information.
SRT Vehicles
The Daytime Running Lights (bright inten-
sity) come on whenever the engine is running,

nighttime driving.
High Beams
Push the multifunction lever toward the in-
strument 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
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 automati-
cally switches from high beams to low beams
until the approaching vehicle is out of view.NOTE:

trol 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. Re-
fer to “Uconnect Settings” in “Multimedia”
in the Owner’s Manual 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 func-
tion improperly.
• To opt out of the Advanced Auto High-Beam
Sensitivity Control (default) and enter Re-
duced High-Beam Sensitivity Control (not
recommended), toggle highbeam lever
6 full on/off cycles within 10 seconds of

• The gauge may take up to five seconds to
update after adding a gallon or more of
Diesel Exhaust Fluid (DEF) to the DEF tank.
If you have a fault related to the DEF
system, the gauge may not update to the
new level. See your authorized dealer for
service.
• The DEF gauge may also not immediately
update after a refill if the temperature of
the DEF fluid is below 12F (-11C). The DEF
line heater will possibly warm up the DEF
fluid and allow the gauge to update after a
period of run time. Under very cold condi-
tions, it is possible that the gauge may not
reflect the new fill level for several drives.TRIP COMPUTER
Push and release the up or down arrow button
until the Trip A or Trip B icon is highlighted in

WARNING LIGHTS AND
MESSAGES
The warning/indicator lights will illuminate in
the instrument panel together with a dedi-
cated message and/or acoustic signal when
applicable. These indications are indicative
and precautionary and as such must not be
considered as exhaustive and/or alternative
to the information contained in the Owner’s
Manual, which you are advised to read care-
fully in all cases. Always refer to the informa-
tion 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 op-tions and current vehicle status. Some tell-
tales are optional and may not appear.
Red Warning Lights

This light indicates 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 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,

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 hy-
draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion 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 indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied 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.
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.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic 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 re-
quired.
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
four seconds. The light should then turn off
unless the parking brake is applied or a brake
fault is detected. If the light does not illumi-
nate, have the light inspected by an autho-
rized 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 light illuminates when the battery is not
charging properly. If it stays on while the
engine is running, there may be a malfunc-
tion with the charging system. Contact your
authorized dealer as soon as possible.

Electronic Throttle Control (ETC) system. If a
problem is detected while the vehicle is run-
ning, the light will either stay on or flash
depending on the nature of the problem.Cycle the ignition when the vehicle is safely
and completely stopped and the transmission
is placed in the PARK position. The light
should turn off. If the light remains on with
the vehicle running, your vehicle will usually
be drivable; however, see an authorized
dealer for service as soon as possible.
NOTE:
This light may turn on if the accelerator and
brake pedals are pressed at the same time.
If the light continues to flash when the ve-
hicle is running, immediate service is re-
quired and you may experience reduced per-
formance, an elevated/rough idle, or engine
stall and your vehicle may require towing.
The light will come on when the ignition is
placed in the ON/RUN or ACC/ON/RUN posi-
tion and remain on briefly as a bulb check. If
the light does not come on during starting,
have the system checked by an authorized
dealer.
— Engine Coolant Temperature Warn-
ing Light
This light warns of an overheated engine
condition. If the engine coolant temperature
is too high, this indicator will illuminate and
a single chime will sound. If the temperature
reaches the upper limit, a continuous chime
will be sound for four minutes or until the
engine is able to cool: whichever comes first.
If the light turns on while driving, safely pull
over and stop the vehicle. If the A/C system is
on, turn it off. Also, shift the transmission
into NEUTRAL and idle the vehicle. If the
