Battery Saver On/Battery Saver Mode
Message — Electrical Load Reduction
Actions — If Equipped
This vehicle is equipped with an Intelligent Bat-
tery Sensor (IBS) to perform additional monitor-
ing of the electrical system and status of the
vehicle battery.
In cases when the IBS detects charging system
failure, or the vehicle battery conditions are dete-
riorating, electrical load reduction actions will take
place to extend the driving time and distance of
the vehicle. This is done by reducing power to or
turning off non-essential electrical loads.
Load reduction is only active when the engine is
running. It will display a message if there is a
risk of battery depletion to the point where the
vehicle may stall due to lack of electrical supply,
or will not restart after the current drive cycle.
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 reduction. The charging system per-
forms 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 Messages”
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
•
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 be-
cause the electrical loads are larger than the
capability of charging system. The charging
system is still functioning properly.
