Routine maintenance is the self-explanatory term used to describe the sort of periodic work necessary to keep a car in safe and reliable working order. A regular program aimed at monitoring essential systems ensures that the car's components are functioning correctly (and will continue to do so until the next inspection, one hopes), and can prevent small problems from developing into major headaches. Routine maintenance also pays off big dividends in keeping major repair costs at a minimum, extending the life of the car, and enhancing resale value, should you ever desire to part with your Mercedes.

A very definite maintenance schedule is provided by Mercedes-Benz, and must be followed, not only to keep the new car working properly. The "Maintenance Intervals" chart in this section outlines the routine maintenance which must be performed according to intervals based on accumulated mileage. Your car also came with a maintenance schedule provided by Mercedes-Benz. Adherence to these schedules will result in a longer life for your car, and will, over the long run, save you money and time.

The checks and adjustments in the following sections generally require only a few minutes of attention every few weeks; the services to be performed can be easily accomplished in a morning. The most important part of any maintenance program is regularity. The few minutes or occasional morning spent on these seemingly trivial tasks will forestall or eliminate major problems later.
