It could be anything from the gas cap not being turned enough (3 clicks) or something more serious. You can take it to an Autozone and plug it into their machine for free in order to find out what the messages mean. There is usually a code that relates to a sensor. Sensor could be out, or mechanical problem.

First thing to do is check your car manual to find specific problems related to the lights. If that does not help, having an expensive car like that the best thing to do would be to go a professional and have them look at it.

Some car manufacturers schedule the service light to come on at a specified interval just to get your car into the service professionals. Certain items on the car, notably the smog equipment, need to be serviced regularly, but do not result in performance problems for the driver.
