alternator PONTIAC G6 2009 Owners Manual

Parade Dimming
Parade mode automatically prohibits the dimming of the
instrument panel displays during the daylight while
the headlamps are on so that the displays are still able
to be seen.
Reading Lamps
For vehicles with front and rear reading lamps, press
the lens to turn the lamp on and off, while the doors are
closed. These lamps come on automatically when
any door is opened.
Trunk Lamp
The trunk lamp comes on when the trunk is opened and
turns off when the trunk is closed.
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 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.
