Battery Load
Management
The vehicle has Electric PowerManagement (EPM), whichestimates the battery's temperatureand state of charge. It then adjuststhe voltage for best performanceand extended life of the battery.
When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. The voltmetergauge or the voltage display on theDriver Information Center (DIC),if equipped, may show the voltage
moving up or down. This is normal.If there is a problem, an alert will bedisplayed.
The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.This is because the generator(alternator) may not be spinning fastenough at idle to produce all thepower that is needed for very highelectrical loads.
Ahighelectricalloadoccurswhenseveral of the following are on, suchas: headlamps, high beams, foglamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.
EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speed togenerate more power, wheneverneeded. It can temporarily reducethe power demands of someaccessories.

Normally, these actions occur insteps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable to thedriver. If so, a DIC message mightbe displayed and it is recommendedthat the driver reduce the electricalloads as much as possible. SeeBattery Voltage and ChargingMessages0150.
Battery Power Protection
This feature shuts off the dome andreading lamps, if they are left on formore than 10 minutes after theignition is turned off. The cargolamp shuts off after 20 minutes. Thisprevents the battery fromrunning down.
