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.
Ve h i c l e   w a s h i n g
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.In the winter, thoroughly remove all traces of road salt 
as soon as possible.
When washing the underbody, do not forget to clean the 
inner sides of the wheels.
Ornamental moldings
For regular cleaning and care of very dirty chrome-
plated parts, use a chrome cleaner.
Headlamps, taillamps, turn signal lenses
Use a mild car wash detergent, such as Mercedes-Benz 
approved Car Shampoo, with plenty of water.
To prevent scratches, never apply strong force and use 
only a soft, non-scratchy cloth when cleaning the lenses. 
Do not attempt to wipe dirty lenses with a dry cloth or 
sponge.

Clean with soft bristle brush, or use a dry-shampoo 
cleaner in case of excessive dirt.
Upholstery
Using aftermarket seat covers or wearing clothing that 
have the tendency to give off coloring (e.g. when wet 
etc.) may cause the upholstery to become permanently 
discolored. By lining the seats with a proper 
intermediate cover, contact-discoloration will be 
prevented.
Leather Upholstery
Wipe leather upholstery with a damp cloth and dry 
thoroughly or clean with Mercedes-Benz approved 
Leather Care. Exercise particular care when cleaning 
perforated leather as its underside should not become 
wet.

lint-free cloth and apply with light pressure.
Plastic and rubber parts
Do not use oil or wax on these parts.
Wa r n i n g !
Do not bleach or dye seat belts as this may severely 
weaken them. In a crash they may not be able to 
provide adequate protection.
