Chevrolet 1998 Lumina Owner's Manual page 115

Battery Saver
Your vehicle has a feature to help prevent you from
draining the battery, in case you accidentally leave the
courtesy lamps on. If you leave the dial turned all the
way up, or if you leave a door open, the lamps will
automatically turn off after 10 minutes if the ignition
is off.
This feature will not turn off the reading lamps, only
the lamps controlled by the dial. Be sure to turn off
any reading lamps using the switch before you leave
the vehicle.
