Regular Maintenance Is Very Important!
Wash the underside of your vehicle.
Unless a Mercedes-Benz owner does their own repairs, most people will never see the underside of their vehicle. However, many cities with a snowy climate use salt to de-ice their roads, resulting in a slushy mixture that ends up on the undercarriage of your Mercedes-Benz. This mixture can eat away at important mechanical and structural components of your vehicle. During the winter months make sure you clean the undercarriage at least once a month, and one final time when the season is over to ensure the last of the mixture is removed.
Check your ignition system.
The ignition system on your Mercedes-Benz is a good indicator of how your car is performing. Take your Mercedes-Benz into your dealership and have them check the system, especially the spark plugs, every 30,000 miles. Spark plugs should be replaced when necessary or at 100,000 miles. This system is easy to forget about as most people will never see their spark plugs, but they are equally important to maintain.
Replace your filters.
Again, your vehicle’s filters are something most owners will never see, but your Mercedes-Benz uses several for both oil and fuel. These filters are crucial for preventing debris and rust from entering the internal components of your engine. Filters should be checked every three thousand miles and replaced when they are clogged.
Track your mileage.
Perhaps the best gauge of how a Mercedes-Benz is performing is fuel efficiency. To track the fuel efficiency of a vehicle, record the amount of gas purchased each time the tank is refilled, and the mileage on the odometer. By doing this one can determine how many miles the vehicle is getting for every gallon of gasoline. Many newer vehicles will track this for you on an inboard computer system. If a big decline in fuel efficiency is noticed, bring the vehicle in for a check up as soon as possible.
Hope this helps!
