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 o12V, 115V AC, USB ports)
during certain driving conditions (city driving, towing,
frequent stopping).
•
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 o12V,
115V AC, USB ports
– Check HVAC settings (blower, temperature)
– Check the audio settings (volume)
After a trip:
•
Check if any aftermarket equipment was installed (ad-
ditional lights, upfitter electrical accessories, audio sys-
tems, alarms) and review specifications if any (load and
Ignition Off Draw currents).
•
Evaluate the latest driving cycles (distance, driving time
and parking time).
