"Private mode", you have to perform the
necessary steps on the mobile phone (see
the separate mobile phone operating
instructions).

Engine compartmentMaintenance and care

Example: vehicles with a diesel engine
X
Park the vehicle on a level surface.
To check the oil level with the engine at
normal operating temperature, switch the
engine off and wait for approximately five
minutes.
X Pull oil dipstick :outoft he oil dipstick
tube.
X Wipe off oil dipstick :.
X Slowly slide oil dipstick :into the guide
tube to the stop, and take it out again.
If the level is between MIN mark =and
MAX mark ;, the oil level is correct.
X If the oil level has dropped to MIN mark
= or below it, top up with
0.5 to 1.0 litres of engine oil.
Adding engine oil G
WARNING
If engine oil comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any engine oil on hot
engine parts. H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment.
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off. Example: engine oil cap
X
Turn cap :anti-clockwise and remove it.
X Top up the engine oil.
If the oil level is at or below the MIN mark
on the dipstick, top up with
0.5 to 1.0 litres of engine oil.
X Replace cap :on the filler neck and turn

Slowly tur ncap : half a turn anti-clock-
wise and allow excess pressure to escape.
X Turn cap :further anti-clockwise and
remove it.
If the coolant is at the level of marker bar
= in the fille rneck when cold, there is

warm, there is enough coolant in coolant
expansion tank ;.

Windscreen washer system and head-
lamp cleaning system The washer fluid reservoir is used for both the
windscreen washer system and the headlamp
cleaning system.
i
Components and service products must
be matched. Mercedes-Benz recommends
that you use products tested and approved
by Mercedes-Benz. They are listed in this
Mercedes-Ben zOwner's Manual in the
appropriate section. You can identify service products approved
by Mercedes-Ben
zby th efollowing inscrip-
tions on the container:
R MB-Freigabe (e.g. MB-Freigabe 371.0)
R MB-Approval (e.g. MB-Approval 371.0)
Other labels and recommendations that
make reference to quality level or a speci-
fication according to an MB Sheet no. (e.g.
MB 371.0) are not necessarily approved by
Mercedes-Benz.
You can obtain further information from
any Mercedes-Benz Service Centre. G
WARNING
Windscreen washer fluid is highly flammable.
Fire, naked flames and smoking are prohibi-
ted when handling washer fluid concentrate.
! Only use washer fluid concentrate which
is suitable for plastic lamp lenses. Unsuit-
able washer fluid concentrate could dam-
age the plastic lamp lenses of the head-
lamps.
! Do not use distilled or de-ionised water in
the washer fluid reservoir. Otherwise, the
level sensor may be damaged.
i Add windscreen washer concentrate, e.g.
MB SummerFit, to the washer fluid all year
round. Example: washer fluid reservoir
X
Mix the windscreen washer fluid in a con-
tainer beforehand.
X At temperatures above freezing: fill the
washer fluid reservoir with amix of water Engine compartment
325Maintenance and care Z

X
Remove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighte rfluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Care and treatment of matt paintwork If your vehicle has a clear mat
tfinish, observe
the following instructions in order to avoid
damage to the paintwork due to incorrect
care.
These notes also apply to light alloy wheels
with a clear mat tfinish.
! Neve rpolish the vehicle or the light alloy
wheels. Polishing makes the paintwork
shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R Vigorous rubbing with unsuitable mate-
rials.
R Frequent use of car washes.
R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or pol-
ishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matt finish leads to considerable sur-
face damage (shiny, spotted areas).
Always have paintwork repairs performed
at a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
! Do not use wash programs with a hot wax
treatment under any circumstances. i
The vehicle should preferably be washed
by hand using a soft sponge, car shampoo
and plenty of water.
i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products.
Cleaning the windows G
WARNING
Switch off the windscreen wipers and remove
the key from the ignition lock before cleaning
the windscreen or the wiper blades. On vehi-
cles with KEYLESS-GO, press the Start/Stop
button repeatedly until all indicator lamps in
the instrument cluster have gone off. The
windscreen wipers could otherwise move and
injure you.
! Only fold the windscreen wipers away
from the windscreen when vertical. Other-
wise, you will damage the bonnet.
X Clean the inside and outside of the win-
dows with a damp cloth and a cleaning
agent that is recommended and approved
by Mercedes-Benz.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the inside of the windows.
Do not touch the insides of the windows
with hard objects, e.g. an ice scraper or
ring. There is otherwise a risk of damaging
the windows.
! Clean the water drainage channels of the
windscreen and the rear window at regular
intervals. Deposits such as leaves, petals
and pollen may under certain circumstan-
ces prevent water from draining away.T his
can lead to corrosion damage and damage
to electronic components.
