Cargo Lamp

The cargo lamp is located over the rear compartment,

and is controlled by the dome lamp. See Dome Lamp on

page 3-17.

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 put the charge back in. When

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

to prevent overcharging. If the vehicle has a voltmeter

gage 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 loads are on: 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 or Service Battery Charging System. 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 3-52.
