How does the Door Alarm work and how do I reset it?

Press DOOR ALARM to turn the alarm on; if either compartment door is left open for more than 10 minutes, the alarm will sound every 2 minutes and the indicator light will flash. Reset the Door Alarm by simply closing the door. Note that interior lights will turn off if a door is left open for more than 10 minutes whether the alarm is on or off. (Page 4)
