Pontiac 2004 GTO - Manual (Page 114)

Front Reading Lamps
Your vehicle has reading lamps located in the dome
lamp. The lamps can be turned on and off manually by
pressing the side of each reading lamp when the
doors are closed.
Trunk Lamp
The trunk lamp comes on when you open your trunk.
Battery Run-Down Protection
Your vehicle has a battery run-down protection feature
designed to protect your vehicle’s battery.
It will activate when there has been no electrical change
for one hour, nothing has been turned on or off, after
the ignition has been turned to ON or ACCESSORIES.
At this time, all the interior lamps will turn off: dome,
reading, glovebox, trunk.
The system is turned on if a door is opened, the vehicle
is unlocked, or the trunk is opened. Once the system
is turned on, the one hour battery protection time resets
to zero and the interior lamps will continue to operate
for another hour, or until the vehicle is locked.
The interior lamp system will shut down 10 seconds
after your vehicle is locked using either the key or the
remote key locking system. However, if an interior lamp,
such as the dome lamp, has been turned on manually
and is on at the time the vehicle is locked, the
system will not shut down after the normal 10 seconds.
The one hour battery protection will be activated
instead.
The vehicle’s hazard lights will continue to operate at
all times.
Accessory Control
If you want the accessories to operate once the key has
been removed from the ignition, you must turn the
system on by either manually starting an accessory,
such as turning the radio on again. This will activate a
one hour timer that will operate accessories such as
the radio, accessory power outlet, and windshield wipers
before turning off. These actions will reset the timer to
zero. Likewise, if an accessory such as the radio is
turned on at any time during the one hour period, the
timer is reset to zero and all accessories will continue to
operate for another hour. To enable accessory control
after the system has been reset, you must turn the
ignition on and then off again.
