NOTE:
• The charging system is independent from load reduction.The charging system performs a diagnostic on the
charging system continuously.
• If the Battery Charge Warning Light is on it may indicate a problem with the charging system. Refer to “Battery
Charge Warning Light” in “Getting To Know Your Instru -
ment Panel” for further information.
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
• 115V 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 +12V, 115V 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, +12V
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 exterior).
•Check what may be plugged in to power outlets +12V,115V AC, USB ports.
•Check HVAC settings (blower, temperature).
•Check the audio settings (volume).
After a trip:
• Check if any aftermarket equipment was installed (addi -
tional 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 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.

308 STARTING AND OPERATING
When to Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting occurs,
push the TOW/HAUL switch to activate TOW/HAUL
mode. This will improve performance and reduce the poten-
tial for transmission overheating or failure due to excessive
shifting.
TOW/HAUL Switch The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate that TOW/HAUL mode has
been activated. Pushing the switch a second time restores
normal operation. Normal operation is always the default at
engine start-up. If TOW/HAUL mode is desired, the switch
must be pushed each time the engine is started.
ACTIVE NOISE CANCELLATION
Your vehicle is equipped with an Active Noise Cancellation
System. This system is designed to address exhaust and
engine noise. The system relies on four microphones
embedded in the headliner, which monitor exhaust and
engine noise, and assists an onboard frequency generator,
which creates counteracting sound waves in the audio
system’s speakers. This helps keep the vehicle quiet at idle
and during drive.
WARNING!
Do not use the “TOW/HAUL” feature when driving in
icy or slippery conditions. The increased engine braking
can cause the rear wheels to slide, and the vehicle to
swing around with the possible loss of vehicle control,
which may cause an accident possibly resulting in
personal injury or death.
