• Always place the load against the rear or front seat backrests. Make sure that the seat backrests are securely locked into place.
• Always place the load behind unoccupied seats if possible.
• Use the cargo tie down rings and the parcel nets to transport loads and luggage.

• regular city driving with frequent intermediate stops
• if the vehicle is primarily used to travel short distances
• use in mountainous terrain or on poor road surfaces
• if the engine is often left idling for long periods
  Under these or similar conditions, have, for example, the air filter, engine oil and oil filter replaced or changed more frequently. Under arduous operating conditions, the tires must be checked more often. Further information can be obtained at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.
