108GETTING TO KNOW YOUR INSTRUMENT PANEL
When load reduction is activated, the message “Battery
Saver On” or “Battery Saver Mode” 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 reduc -
tion. 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
Úpage 109.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be affected by load
reduction:
 Heated Seat/Vented Seats/Heated Wheel
 Rear Defroster And Heated Mirrors
 HVAC System
 115 Volt 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 the 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, over -
loaded power outlets +12 Volt, 115 Volt AC, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping, etc.).
 Installing options like additional lights, upfitter elec -
trical 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 exterior)
 Check what may be plugged in to power outlets
+12 Volt, 115 Volt 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 if
the evaluation and driving pattern of the vehicle 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.
