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 capa-
bility of charging system. The charging system
is still functioning properly.
• Turning on all possible vehicle electrical loads
(e.g. HV AC to max settings, exterior and inte-
rior lights, overloaded power outlets +12V,
115V AC, USB ports) during certain driv-
ing conditions (city driving, towing, frequent
stopping).
• Installing options like additional lights, upfit-
ter 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 exte-
rior)
– Check what may be plugged in to power
outlets +12V, 115V AC, USB ports
– Check HVAC settings (blower, tempera-
ture)
– Check the audio settings (volume)
After a trip:
• Check if any aftermarket equipment was in-
stalled (additional lights, upfitter electrical
accessories, audio systems, alarms) and re-
view 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 consecu-
tive 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 instrument panel together with a dedicated
message and/or acoustic signal when appli-
cable. These indications are indicative and pre-
cautionary and as such must not be considered
as exhaustive and/or alternative to the informa-
tion 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 tell-
tales 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 .
