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 this section for further information.
