Lower the bonnet and let it fall from a
heightofa pproximately 20 cm.
X Check that the bonnet has engage dprop-
erly.
i If the bonnet can be raiseds lightly, it is
not properl yengaged. Open it again and
close it with alittle more force. Engine oil
Depending on driving style, the vehicle con-
sumes up to 0.8 loil per 1,000 km. The oil
consumption may be highert han this when
the vehicle is new or if you frequently drive at
high engine speeds.
Checking the engine oil level Before checking the engine oil level the fol-
lowing conditions for the vehicle shouldbe
met:
R
the vehicle shouldbep arked on level
ground.
R the engine shouldbes witched off for at
least five minutes if the engine is at normal
operating temperature.
R the engine shouldbes witched off for at
least 30 minutes if the engine is not at
operating temperature (i.e. if you only start
the engine briefly).
Depending on the engine, the oil dipstick may
be installed at adifferent location. E3

Pullo il dipstick 0046out of the oil dipstick
tube.
X Wipe off oil dipstick 0046.
X Insert oil dipstick 0046into the oil dipstick
tube to the stop, and take it out again.
The oil level is correct if the level is between
the minimum mark 008Aand maximum
mark 0047.
X Top up the oil if necessary.
Topping up the engine oil H
Environmental note
When topping up the oil, take care not to spill
any. Oil must not be allowed to escape into
the soil or waterways. You would otherwis ebe
damaging the environment. Cap (example)
X Turn cap 0046anti-clockwise and remove.
X Top up with the amount of oil required
(Y page 288).
i The difference in quantity betwee nthe
minimum mark and maximu mmark is
approximately 2litres.
i On vehicle switha4-cylinder petrol
engine and vehicle swith an 8-cylinder pet-
rol engine, the difference betwee nthe MIN
mark and the MAX mark is approximately
1.5 litres.
! Do not add too much oil. If too much oil
is added and the oil level is above the max- 182

distance.
R Fit new tyres on the front wheels first if
tyres of the same size are required on the
front and rear wheels.
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the spare wheel*.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
! Storet yres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel.
Notes on regularly inspecting wheels
and tyres R
Regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracksors evere corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause aloss of tyre pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whole
width of the tyre (Y page 186). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have avalve cap to protect
the valve against dirt and moisture. Do not
fit anything ontot he valve (such as tyre
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your vehi-
cle.
R Regularly check the pressure of all the tyres
including the spare tyre* ,particularly prior
to long trips, and correc tthe pressure as
necessary (Y page 186). Notes on driving R
While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi-
cate that the wheels or tyres are damaged.
If you suspect that atyre is defective,
reduce your speed and stop the vehicle as
soon as possible to check the wheels and
tyres for damage. Hidden tyre damage
could also be causing the unusual handling
characteristics. If you find no signs of dam-
age, have the wheels and tyres examined
at as pecialist workshop, for example at a
Mercedes-Benz Servic eCentre.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar eleva-
tions, try to do so slowly and at an obtuse
angle. Otherwise, the tyres, particularly the
sidewalls, can get damaged. Direction of rotation
Tyres with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
of aquaplaning. You will only gain these ben-
efits if the correc tdirection of rotation is
observed.
An arrow on the sidewal lofthe tyre indicates
its correc tdirection of rotation. MOExtended run-flat system*
The MOExtended run-flat system allows you
to continue driving the vehicle even when one
or more tyres lose all air pressure.
The MOExtended run-flat system may only be
used in combination with the activated tyre
pressure loss warning system and only on
wheels specifically tested and approved by
Mercedes-Benz. Tyres and wheels

Risk of injury
When cleaning the steering wheel boss and

cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
