Wind buffeting can be described as the perception of pres-
sure on the ears or a helicopter-type sound in the ears. Your
vehicle may exhibit wind buffeting with the windows down,
or the sunroof (if equipped) in certain open or partially open
positions. This is a normal occurrence and can be minimized.
If the buffeting occurs with the rear windows open, open the
front and rear windows together to minimize the buffeting.

Power Inverter — If Equipped
If equipped, a 115 Volt (400 Watts Maximum) inverter may
be located inside the center console towards the right hand
side, just under the Wireless Charging Pad (if equipped).
This inverter can power cellular phones, electronics andother low power devices requiring power up to 400 Watts.
Certain high-end video game consoles exceed this power
limit, as will most power tools.
Center Console Power Inverter Outlet
There is also a second 115 Volt (400 Watts Maximum) power
inverter located on the rear of the center console. This
inverter can power cellular phones, electronics and other low
power devices requiring power up to 400 Watts. Certain
high-end video game consoles exceed this power limit, as
will most power tools.
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.). Eventually, 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 accesso -
ries still plugged in), the vehicle must be driven a suffi -
cient length of time to allow the generator to recharge
the vehicle's battery.

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.
