WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
If any of the doors are open, with ignition switch "ON" and with vehicle running at the speed of 8 km/h (5 mph) or more, ETACS-ECU makes buzzer sound.
