Dome Lamp Override; Entry/Exit Lighting; Reading Lamps; Electric Power Management - GMC 2010 Savana 1500 Cargo Owner's Manual

Dome Lamp Override

The dome lamp override button is located next to the
exterior lamps control.
The dome lamp override sets the dome lamps to remain
off or come on automatically when a door is opened.
E
(Dome Lamp Override): Press the button in
and the dome lamps remain off when a door is opened.
Press the button again to return it to the extended
position so that the dome lamps come on when a door
is opened.

Entry/Exit Lighting

The vehicle has an illuminated entry/exit feature.
The dome lamps come on if the dome override button is
in the out position, when a door is opened or the key
is removed from the ignition.

Reading Lamps

For vehicles with reading lamps, press the button
located next to each lamp to turn it on or off.
The vehicle may also have reading lamps in other
locations. The lamps cannot be adjusted.

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.
