WARNING
Braking efficiency is reduced after the vehicle
has been washed. There is a risk of an acci-
dent.
After washing the vehicle, brake carefully
while paying attention to the traffic conditions
in order to restore full braking efficiency.
! Before washing the vehicle in an auto-
matic car wash, fold in the exterior mirrors
and switch off the windscreen wipers. Oth-
erwise, the exterior mirrors and windscreen
wipers could be damaged.
Make sure that the exterior mirrors are fully
folded out again when you leave the auto-
matic car wash.
Wash off excess dirt before cleaning the vehi-
cle in an automatic car wash.

Cleaning and care
After the automatic car wash, remove the wax
from the windscreen and the wiper blades.
This prevents smearing and reduces wiper
noise, which occur as a result of residue on
the windscreen.
Cleaning the engine
! Observe the following notes when clean-
ing the engine. This avoids malfunctions
and damage to the engine.
When using high-pressure or steam
R
cleaners, do not point the spray directly
at electrical components and electric
cables.
Make sure that no water enters the air
R
intake and ventilation openings.
Treat the engine with preservative
R
agents after it has been cleaned. When
doing so, protect the belt drive system
from the preservative agent.
Only use wax-based protective agents
R
for engines that comply with
Sheet No. 385.4 of the Mercedes-Benz
Specifications for Service Products.
! When using high-pressure or steam clean-
ers, do not point the spray directly at radi-
ator core fins, electrical components or
electric cable ends.
In addition, observe the notes in the "High-
pressure cleaning" section (
Cleaning light-alloy wheels
! When cleaning the light-alloy wheels, do
not use any acidic or alkaline cleaning
agent. They may corrode the wheel nuts or
the locking springs of the wheel balance
weight.
! Do not point the water jet of high pressure
or steam cleaners directly at the balance
weights of the light-alloy wheel. They may
become detached and lead to imbalance
and increased tyre wear.
