"Tune up" here refers to a car "tune up", which describes preventative maintenance that is done on a car to make sure that the car works well. It is recommended that a car gets a "tune up" about once a year, but this is just a suggestion. One's car might not need a "tune up" or need one very often if the car is newer.
