The exact meaning might vary slightly depending on the year and model of your Town & Country, but it's almost certainly related to a malfunction within the ESP/ESC system. You should consult your owner's manual for the specific meaning in your vehicle's context, but it's a warning that warrants attention. Driving with this light on reduces your vehicle's safety features designed to help prevent loss of control.
You should have the vehicle checked by a mechanic as soon as possible to diagnose and fix the underlying problem. Ignoring it could lead to dangerous driving conditions.
