electrical power to the vehicle system be-
cause the electrical loads are larger than
the capability of charging system. The

erly.

loads (e.g. HVAC to max settings, exterior
and interior lights, overloaded power out-
lets +12V, 150W, USB ports) during certain
driving conditions (city driving, towing, fre-
quent stopping).

action message is present ("Battery Saver On"
or "Battery Saver Mode")

exterior)
– Check what may be plugged in to power
outlets +12V, 150W, USB ports
– Check HVAC settings (blower, tempera-
ture)
– Check the audio settings (volume)
After a trip:
• Check if any aftermarket equipment was
installed (additional lights, upfitter electri-
cal accessories, audio systems, alarms)
and review specifications if any (load and
Ignition Off Draw currents).

driving time and parking time).
• The vehicle should have service performed
if the message is still present during con-
secutive trips and the evaluation of the
vehicle and driving pattern did not help to
identify the cause.
