Engine Cleaning
Corrosion protection, such as MB
Anti-corrosion Wax, should be applied
to the engine compartment after every
engine cleaning. Before applying, all
control linkage bushings should be
lubricated. The poly-V-belt and all
pulleys should be protected from any
wax.
Car Washing
Before washing your vehicle, remove
insect residues. MB Insect Remover is
recommended. Do not use hot water
or wash your car in direct sunlight.
Use only a mild car wash detergent,
such as MB Autoshampoo.
Thoroughly spray the car 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 und thourough-
ly wipe dry with a chamois. Do not
allow cleaning agents to dry on the
finish.
If the vehicle has been run through an
automatic car wash - in particular one
of the older installations - rewipe the
recessed sections in the taillamps
(designed to prevent soiling) if neces­
sary. No solvents (fuels, thinners etc.)
must be used.
In the winter, thoroughly remove all
traces of road salt as soon as possi­
ble.
When washing the underbody, do not
forget to clean the inner sides of the
wheels.
Tar Stains
Quickly remove tar stains before they
dry and become more difficult to
remove. MB Tar Remover is recom­
mended.
Window Cleaning, Wiper Blades
Use a window cleaning solution on
very dirty or oil-stained windows.
Clean windshield wiper blades with a
clean cloth and detergent solution.
Replace blades twice a year; once
before and once after winter.
Headlamp Cleaning System
The condition of the wiper blades is
important for satisfactory cleaning of
the headlamp lenses. We therefore
recommend that the blades be
inspected regularly.
Replace damaged wiper blades.
Plastic Parts, Headliner and Rubber
Parts
Do not use oil or wax on these parts.
Seat Belts
The webbing must not be treated with
chemical cleaning agents. Use only
clear, lukewarm water and soap. Do
not dry the webbing at temperatures
above 80°C (176°F) or in direct
sunlight.
Warning!
Do not bleach or dye seat belts
as this may severely weaken
them. In a crash they may not be
able to provide adequate protec­
tion.
Instrument Cluster
Use a gentle dish-washing detergent
or mild detergent for delicate fabrics
as a washing solution. Wipe with a
cloth moistened in lukewarm solution.
Do not use scouring agents.
Steering Wheel and Selector Lever
Wipe with a damp cloth and dry
throughly or clean with MB-Leather
Cleaner.
