I just purchased my first Volvo ('91 240 SE wagon, 5-speed manual, 120,000 miles) and of course I have some questions that probably have been answered here before, but I can't find them.

First, this car has a shift indicator light, which tells the driver when to shift, presumably to get better gas mileage. What is the real world recommendation for following this light? It seems that I'm shifting up at really low speeds and may be lugging the engine. So tell me if you use the light or not.

Second, what does SE mean? The guy I bought it from didn't know.

Third, towing. I understand I can acquirea tow hitch for the vehicle. Is this really recommended. The engine doesn't seem to have that much oomph as it is and I can't see towing a 3,000 pound trailer with it. I may get a utility trailer, however, and get rid of my F150 truck.

As a newbie, I'm sure I will have many more questions, but I'm loving the comfort of this car and it seems to be getting pretty decent mileage (of course, compared to a big truck). Any help will be appreciated.
