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 pul­
leys 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 Auto-shampoo.
Thoroughly spray the car with a dif­
fused jet of water. Direct only a very
weak spray towards the ventilation in­
take. Use plenty of water and rinse the
sponge and chamois frequently.
Rinse with clear water and tho­
roughly 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 partic­
ular one of the older installations -
rewipe the recessed sections in
the taillamps (designed to prevent soil­
ing) 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.
Note:
It is advisable to lock the trunk lid be­
fore using an automatic car wash.
The wash brush could inadvertently
open the trunk lid.
Tar Stains
Quickly remove tar stains before they
dry and become more difficult to re­
move. MB Tar Remover is recom­
mended.
Window Cleaning, Wiper Blade
Use a window cleaning solution on
very dirty or oil-stained windows.
Clean the wiper blade rubber with a
clean cloth and detergent solution.
Replace blade twice a year; once be­
fore 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 in­
spected regularly.
Replace damaged wiper blades.
