GM Service Manual Online
For 1990-2009 cars only

The vehicle has a battery run-down protection feature designed to protect the vehicle's battery.

When any interior lamp (trunk, reading, or visor vanity) is left on while the ignition is turned off, the battery run-down protection system will automatically shut the lamp(s) off after 20 minutes. This will avoid draining the battery.

To reactivate the interior lamps, do one of the following:

    • Turn on the ignition.
    • Turn the exterior lamp control off and then on.
    • Open a door.
    • Press any Remote Keyless Entry (RKE) transmitter button (if equipped).
    • Press the remote trunk release button.
    • Press the power door lock switch.

The battery run-down feature will also be activated when any door on the vehicle is left open and the ignition is in LOCK/OFF.
