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. |
