186 GETTING 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 display.
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. Refer to "Battery
Charge Warning Light" in "Warning Lights And Mes-
sages" located in "Getting To Know Your Instrument
Panel" for further information.
The electrical loads that may be switched off (if equipped),
and vehicle functions which can be effected by load reduction:
• Heated Seat/Vented Seats/Heated Wheel
• Rear Defroster And Heated Mirrors
• HVAC System
• 150W 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, 150W, USB ports) dur-
ing certain driving conditions (city driving, towing,
frequent stopping).
• Installing options like additional lights, upfitter electri-
cal accessories, audio systems, alarms and similar de-
vices.
• 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.
