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
90
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.
Plastic Parts, Headliner
and Rubber Parts
Do not use oil or wax on these parts.
See following page for additional in­
formation.
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. Never bleach or
re-dye the webbing as this may se­
verely weaken the belts.
Steering Wheel, Gear Shift Lever
and 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.
