Battery Run-Down Protection
This feature shuts off the dome, courtesy, and vanity lamps if they are left on for more than 20 minutes when the ignition is off. This will keep the battery from running down.
If the battery run-down protection shuts off the interior lamps, it may be necessary to do one of the following to return to normal operation:
• Shut off all lamps and close all doors.
• Turn the ignition key to RUN.
This feature will also turn off the parking lamps and headlamps under most circumstances, if they are left on. If you would like to turn them back on, turn the exterior lamps knob.
