Pontiac 2004 Bonneville - Manual (Page 141)

Rear Reading Lamps
The rear reading lamps, located over each rear door,
will come on as courtesy lamps when you open
any of the doors while it is dark outside. They will also
come on as part of the interior lighting features listed
previously.
To turn on a reading lamp when the doors are closed,
press either button. Press it again to turn the lamp off.
Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s battery
against drainage from the interior lamps, trunk lamp,
glove box lamp or cigarette lighter. When the ignition is
turned off, the power to these features will automatically
turn off after 10 minutes. Power will be restored for
an additional 10 minutes if any door is opened, the trunk
is opened or the courtesy lamps are turned on. To
restore power back to the cigarette lighter the ignition
must be turned back to ON.
