BTW, the 3M plastic cleaner worked wonders ridding the haziness on the headlight.
The -248 means you are 248 miles overdue for a service - in your case, an "A" service (one wrench is showing on the FSS) which means an oil change. The FSS counts mileage and time, so all that time it sat on the dock and the dealer's lot counts toward the service interval.
