Engine Cleaning
Prior to cleaning the engine
compartment make sure to protect
electrical components and
connectors from the intrusion of
water or cleaning agents.
Corrosion protection, such as MB
Anticorrosion Wax should be ap­
plied 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.
Car Washing
Do not use hot water or wash your
car in direct sunlight. Use only a
mild car wash detergent, such as
Mercedes-Benz approved Car
Shampoo.
Thoroughly spray the car with a
diffused jet of water. Direct only a
very weak spray towards the venti­
lation 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 particu­
lar one of the older installations -
rewipe the recessed 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 difficult
to remove. A tar remover is
recommended.
Window Cleaning
Use a window cleaning solution on
all glass surfaces. An automotive
glass cleaner is recommended.
W iper 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 cleaning
of the headlamp lenses. We there­
fore recommend that the blades be
inspected regularly.
Replace damaged wiper blades.
