The oil consumption may be higher than this
when the vehicle is new or if you frequently
drive at high engine speeds. You can only
estimate the oil consumption after you have
driven a considerable distance.
You will find further information about engine
oil in the "Technical data" section
(Y page 369).

equipment manufacturer concerning the
distance to be maintained between the
nozzle of the high-pressure cleaner and the
vehicle (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door joint
R electrical components
R battery
R connectors
R lights
R seals
Damaged seals or electrical components
can lead to failures or leaks. Cleaning the wiper blades and the out-
side of the windscreen G
Risk of injury
Turn the key to position 0in the ignition
lock before cleaning the windscreen or the
wiper blades. There is otherwise a risk of
the windscreen wipers being set in motion
and causing injury.
X Turn the key to position 1(Y page 75)in the
ignition lock.
X Set the windscreen wipers to position u
(Y page 98) on the combination switch.
X Turn the key to position 0(Y page 75)or
remove it when the wiper arms are vertical.

tion, otherwise you will damage the bonnet.
X Fold the wiper arms away from the wind-
screen until you feel them engage.
X Clean the windscreen and the wiper blades.
X Fold the windscreen wipers back again
before the ignition is switched on. !
Do not clean the wiper blades too often
as this will result in the rubber becoming
porous, leading to wiper noise.
Cleaning the windows !
Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows.
Clean the insides of the windows with a
damp cloth or commercially-available glass
cleaner. Avoid touching the inside of the
rear windscreen and the side windows with
hard objects, e.g. ice scrapers or rings. You
could otherwise cause damage to the win-
dows, rear window heating or aerial on the
rear window.
i Anti-glare film retrofitted to the insides of
the windows could interfere with radio or
mobile phone reception, especially if it is
conductive or metal-coated film. Informa-
tion about anti-glare film can be obtained
from any Mercedes-Benz Service Centre.
