Battery Load Management

The battery load management feature is designed to
monitor the vehicle's electrical load and determine when
the battery is in a heavy discharge condition. During
times of high electrical loading, the engine may idle at
higher revolutions per minute (RPM) than normal to make
sure the battery charges. High electrical loads may occur
when several of the following are on: headlamps, high
beams, fog lamps, rear window defogger, fan on high
speed, heated seats, and engine cooling fans.
If your vehicle's battery remains in a heavy discharge
condition for a long period of time, the fan, rear
defogger, heated seats and heated mirrors will be
disabled and the DIC will display BATTERY SAVER
ACTIVE. This can happen either under long periods of
idling or low speed driving with high electrical loading,
or in the event of a charging system fault.
Monitor the battery voltage when in the BATTERY
SAVER ACTIVE mode.
•
If the voltmeter remains in the shaded area, below
11 volts, when driving then have the charging
system serviced immediately.
•
If the voltage increases above 12 volts then the
battery needs to be recharged. Try driving on
the highway with as few electrical accessories on
as possible.
