A door-ajar display may identify the affected door or show a general warning. Pull over before checking closures, and make sure nothing is obstructing a latch. Do not try to open and reclose a door while moving.
If the warning remains after the doors are securely shut, note which door the display identifies and whether interior lights stay on. Describe those details to 12th Street Auto Care Center. Do not defeat a latch or warning switch as a workaround.
