DAYTIME RUNNING LIGHTS (DRLS)
The Daytime Running Lights (DRLs) come on
whenever the engine is running, and the low
beams are not on. The lights will remain on until
the ignition is placed in the OFF or ACC position, or
the parking brake is engaged.
NOTE:
For vehicles sold in Canada, the Daytime
Running Lights will automatically deactivate
when the front fog lights are turned on.
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 Ucon -
nect system Ú page 234.
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.
Pulling the multifunction lever back will turn the
low beams on.
AUTOMATIC HIGH BEAM HEADLAMP
C
ONTROL — 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 camera mounted on the inside rearview mirror
or a windshield mounted camera. These cameras
detect vehicle specific light and automatically
switch 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 Ú page 234, as well as turning the
headlight switch to the AUTO 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 obstruc -
tions on the windshield or camera lens will
cause the system to function improperly.
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 opt out of the Advanced Auto High Beam
Sensitivity Control (default) and enter Reduced
High Beam Sensitivity Control (not recom -
mended), toggle the high beam lever six full on/
off cycles within 10 seconds of placing the igni -
tion in the ON position. The system will return to
the default setting upon placing the ignition in
the OFF position.
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,

CAUTION!
Many accessories that can be plugged in draw
power from the vehicle's battery, even when
not in use (i.e., cellular phones, etc.). Eventu
-
ally, if plugged in long enough, the vehicle's
battery will discharge sufficiently to degrade
battery life and/or prevent the engine from
starting.
Accessories that draw higher power
(i.e., coolers, vacuum cleaners, lights, etc.),
will discharge the battery even more quickly.
Only use these intermittently and with greater
caution.
After the use of high power draw accessories,
or long periods of the vehicle not being started
(with accessories still plugged in), the vehicle
must be driven a sufficient length of time to
allow the generator to recharge the vehicle's
battery.

BATTERY SAVER ON/BATTERY SAVER
M
ODE MESSAGE — ELECTRICAL LOAD
R
EDUCTION ACTIONS — IF EQUIPPED
This vehicle is equipped with an Intelligent Battery
Sensor (IBS) to perform additional monitoring of
the electrical system and status of the vehicle
battery.
In cases when the IBS detects charging system
failure, or the vehicle battery conditions are
deteriorating, electrical load reduction actions will
take place to extend the driving time and distance
of the vehicle. This is done by reducing power to or
turning off non-essential electrical loads.
Load reduction is only active when the engine is
running. It will display a message if there is a risk
of battery depletion to the point where the vehicle
may stall due to lack of electrical supply, or will not
restart after the current drive cycle.
When load reduction is activated, the message
“Battery Saver On Some Systems May Have
Reduced Power” will appear in the instrument
cluster. These messages indicate the vehicle battery has a
low state of charge and continues to lose electrical
charge at a rate that the charging system cannot
sustain.NOTE:
The charging system is independent from load
reduction. The charging system performs a diag
-
nostic on the charging system continuously.
If the Battery Charge Warning Light is on it may
indicate a problem with the charging system
Ú page 129.
The electrical loads that may be switched off
(if equipped), and vehicle functions which can be
affected by load reduction:
Heated Seats / Vented Seats / Heated Wheel
Rear Defroster And Heated Mirrors
HVAC System
115 Volts AC Power Inverter System
Audio and Telematics System
Loss of the battery charge may indicate one or
more of the following conditions:
The charging system cannot deliver enough
electrical power to the vehicle system because
the electrical loads are larger than the capability
of charging system. The charging system is still
functioning properly.
Turning on all possible vehicle electrical loads
(e.g. HVAC to max settings, exterior and interior
lights, overloaded power outlets +12 Volts,
115 Volts AC, USB ports) during certain driving
conditions (city driving, towing, frequent stop -
ping).
Installing options like additional lights, upfitter
electrical accessories, audio systems, alarms
and similar devices.
Unusual driving cycles (short trips separated by
long parking periods).
The vehicle was parked for an extended period
of time (weeks, months).
The battery was recently replaced and was not
charged completely.
The battery was discharged by an electrical load
left on when the vehicle was parked.
The battery was used for an extended period
with the engine not running to supply radio,
lights, chargers, +12 Volt portable appliances
like vacuum cleaners, game consoles and
similar devices.

What to do when an electrical load reduction
action message is present (“Battery Saver On” or
“Battery Saver Mode”)
During a trip:
Reduce power to unnecessary loads if possible:
Turn off redundant lights (interior or exte -
rior).
Check what may be plugged in to power
outlets +12 Volts, 115 Volts AC, USB ports.
Check HVAC settings (blower, temperature).
Check the audio settings (volume).
After a trip:
Check if any aftermarket equipment was
installed (additional lights, upfitter electrical
accessories, audio systems, alarms) and review
specifications if any (load and Ignition Off Draw
currents).
Evaluate the latest driving cycles (distance,
driving time and parking time).
The vehicle should have service performed if
the message is still present during consecutive
trips and the evaluation of the vehicle and
driving pattern did not help to identify the cause.
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated
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
carefully in all cases. 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
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 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.
