Instruments and controls Operation Driving Instrument cluster display Practical hints Car care Technical data Index Cleaning and care of the vehicle Tar stains Quickly remove tar stains before they dry and become more difficult to remove. A tar remover is recommended. Paintwork, painted body components Mercedes-Benz approved Paint Care should be applied when water drops on the paint surface do not "bead up", normally in 3 to 5 months, depending on climate and washing detergent used. Mercedes-Benz approved Paint Cleaner should be applied if paint surface shows signs of dirt embedding (i.e. loss of gloss). Do not apply any of these products or wax if your vehicle is parked in the sun or if the hood is still hot. Use the appropriate MB-Touch-Up Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, vehicle doors etc.). 384 Engine cleaning Prior to cleaning the engine compartment make sure to protect electrical components and connectors from the intrusion of water and cleaning agents. Corrosion protection, such as MB Anticorrosion Wax should be applied to the engine compartment after every engine cleaning. Before applying, all control linkage bushings and joints should be lubricated. The poly-V-belt and all pulleys should be protected from any wax. Vehicle washing Do not use hot water or wash your vehicle in direct sunlight. Use only a mild car wash detergent, such as Mercedes-Benz approved Car Shampoo. Thoroughly spray the vehicle with a diffused jet of water. Direct only a very weak spray towards the ventilation intake. Use plenty of water and rinse the sponge and chamois frequently. Rinse with clear water and thoroughly wipe dry with a chamois. Do not allow cleaning agents to dry on the finish.
