Electric Power Management The vehicle has Electric Power Management (EPM) that estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery. When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gauge or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads. A high electrical load occurs when several of the following are on, such as: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets. EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as BATTERY SAVER ACTIVE, BATTERY VOLTAGE LOW, or LOW BATTERY. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages on page 4‑63. Battery Run-Down Protection This feature shuts off the dome and reading lamps, if they are left on for more than 10 minutes after the ignition is turned off. The cargo lamp shuts off after 20 minutes. This prevents the battery from running down. 4-16

Electric Power Management

The vehicle has Electric Power Management (EPM) that

estimates the battery's temperature and state of charge.

It then adjusts the voltage for best performance and

extended life of the battery.

When the battery's state of charge is low, the voltage is

raised slightly to quickly bring the charge back up.

When the state of charge is high, the voltage is lowered

slightly to prevent overcharging. If the vehicle has a

voltmeter gauge or a voltage display on the Driver

Information Center (DIC), you may see the voltage

move up or down. This is normal. If there is a problem,

an alert will be displayed.

The battery can be discharged at idle if the electrical

loads are very high. This is true for all vehicles. This is

because the generator (alternator) may not be spinning

fast enough at idle to produce all the power that is

needed for very high electrical loads.

A high electrical load occurs when several of the

following are on, such as: headlamps, high beams, fog

lamps, rear window defogger, climate control fan at high

speed, heated seats, engine cooling fans, trailer loads,

and loads plugged into accessory power outlets.

EPM works to prevent excessive discharge of the

battery. It does this by balancing the generator's output

and the vehicle's electrical needs. It can increase

engine idle speed to generate more power, whenever

needed. It can temporarily reduce the power demands

of some accessories.

Normally, these actions occur in steps or levels, without

being noticeable. In rare cases at the highest levels of

corrective action, this action may be noticeable to the

driver. If so, a Driver Information Center (DIC) message

might be displayed, such as BATTERY SAVER

ACTIVE, BATTERY VOLTAGE LOW, or LOW

recommended that the driver reduce the electrical loads

as much as possible. See

Battery Run-Down Protection

This feature shuts off the dome and reading lamps,

if they are left on for more than 10 minutes after the

ignition is turned off. The cargo lamp shuts off after

20 minutes. This prevents the battery from

running down.
