Engine Cleaning
Corrosion protection, such as MB
Anticorrosion Wax should be ap­
plied to the engine compartment
after every engine cleaning. Be­
fore applying, all control linkage
bushings and joints 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 and
thoroughly wipe dry with a
chamois. Do not allow cleaning
agents to dry on the finish.
Before running the vehicle through
an automatic car wash, fold back
the outside mirrors to prevent
them from getting damaged.
If the vehicle has been run
through an automatic car wash -
in particular one of the older
installations - rewipe the reces­
sed sections in the taillamps
(designed to prevent soiling) if
necessary. No solvents (fuels,
thinners etc.) must be used.
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.
Tar Stains
Quickly remove tar stains before
they dry and become more diffi­
cult to remove. MB Tar Remover
is recommended.
Window Cleaning
Use a window cleaning solution on
very dirty or oil-stained windows.
Wiper Blades
Clean the wiper blade rubber 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 clean­
ing 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 176°F
(80°C) 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 protection.
