My coolant light came on this morning while I was on the highway. Pulled into a service area and had a mechanic looked at it thinking I must have a leak. Well, the tank is full. What can be the cause of it? Bad sensor? Where is the sensor? It is a '96 C280 Sport. Thanks for any idea.

BTW, the car had to be jump started as it had been sitting in the garage for a week. Is the battery on the way out? I think most battery can sit for weeks on end without needing a jump.
