Chevrolet 2007 Automobile User Manual


 
Map Lamps
Your vehicle may have lamps located on the
headliner above the rearview mirror. Push on the
lens in the lamp to turn them on and off.
Cargo Lamp
The cargo lamp is located over the rear
compartment, and is controlled by the dome
lamp. See Dome Lamp on page 161.
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 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.
