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).

only reach their full performanc
eafter this
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

Vehicles with the MOExtended run-flat
system are not equipped with the TIREFIT
kit. 36
It is therefore recommended to additionally
equipy ourvehicle with the TIREFIT kit when
fitting tyres that do not feature run-flat
properties, e.g. winter tyres.
i ATIREFIT kit is availablef rom any quali-
fied specialist workshop, e.g. aMercedes-
Benz Service Centre.
You willf ind notes on driving with aflat tyre
in the "Practical advice" section
(Y page 272). Tyre tread
G
Risk of accident
Bear in mind that:
R tyre grip decreases rapidly on wet roads
when the tread depth is less than 3mm.
Thus, you should replace tyres that have
insufficient tread.
R winter tyres should be replaced when the
tread depth is 4mmorless as they will no
longer provide adequate grip.
R the tread on atyre may not wear evenly.
Thus, you should regularly check the tread
depth and the condition of the tread across
the entire width of all tyres. If necessary,
turn the front wheelstof ull lock in order to
inspect the tyre tread more easily.
Otherwise, you could lose control of the vehi-
cle and cause an accident due to the reduced
grip of the tyres on the road. Tyre pressures
i You willf indatable of tyre pressures for
variouso perating conditions on the inside
of yourv ehicle's fuel filler flap. The applicable valuef
or the "Minispare"
emergency spare wheel*i sstated on the
spare wheel and in the technical data sec-
tion.
The load condition "partially laden" or "fully
laden" is defined in the table by the differing
number of passengers and amount of lug-
gage. The actual number of seats may vary
from this –more information can be found on
the vehicle's registration document.
If no other data is stated, the tyre pressures
specified on the fuel filler flap applyf or all
tyres approved for this vehicle. If
at yre size precedes atyre pressure, the tyre
pressure information following is only valid
for that tyre size. Instead of the complete tyre size, it may be
that only the rim diameter is stated, e.g.

The tyre pressure loss warning system does
not replace the need to regularly check your
vehicle's tyre pressures, since an even loss of
pressure on several tyres at the same time
cannot be detected by the tyre pressure loss
warning system.
The tyre pressure monitor is not able to warn
you of asudden loss of pressure, e.g. if the
tyre is penetrated by aforeign object.
In the event of asudden loss of pressure, bring
the vehicle to ahalt by braking carefully. Do
not make any sudden steerin gmovements
when doing so.
The function of the tyre pressure loss warning
system is limited or delaye dif:
R snow chains are fitted to your vehicle's
tyres.
R road conditions are wintry.
R you are driving on sand or gravel.

nering at high speeds or driving with high
rates of acceleration).
R you are towing avery heavy or large trailer.
R you are driving with aheavy load (in the
vehicle or on the roof).

X Before restarting, consult the table of tyre
pressures on the inside of the fuel filler flap
to ensure that the tyre pressure in all four
tyres is set correctly for the respective
operating conditions.
X Observe the notes in the section on tyre
pressures (Y page 186). G
Risk of accident
The tyre pressure loss warning system can
only give reliable warnings if you have set the
correc ttyre pressure.
If an incorrect tyre pressure is set, these
incorrect values will be monitored.
At yre with insufficien tpressure results in
vehicle instability when driving, thus increas-

G
Risk of accident
Interchange the fron tand rear wheels only if
they have the same dimensions :for example
size, offset ,etc.
After awheel is changed, have the tightening
torque checked at aspecialist workshop that
has the necessary specialist knowledge and
tools to carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz Servic eCentre for this pur-
pose. In particular, work relevant to safety or
on safety-related systems must be carried out
at aq ualified specialist workshop.
The wheels could work loose if they are not
tightened to atorque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correc tsize which have been approved for
Mercedes-Benz vehicles.
The wear patterns on the fronta nd rear tyres
differ, depending on the operating conditions.
Interchange the wheels before aclear wear
patter nhas formed on the tyres. Frontt yres
typically wear more on the shoulders and the
rear tyres in the centre.
On vehicles that have the same size fronta nd
rear wheels you can interchange the wheels
every 5,000 km to 10,00 0kmdepending on
the degree of tyre wear. Do not reverse the
direction of tyre rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time awheel
is interchanged. Check the tyre pressure and,
if necessary, restart the tyre pressure loss
warning system*. Winter driving
Points to remember
Have your vehicle winterproofed at aqualified
specialist workshop, e.g. at aMercedes-Benz
Servic eCentre, at the onset of winter.
Observe the notes in the "Changing awheel"
section (Y page 189). Winter tyres
Use winter tyres at temperatures below
+7 ˚C and in wintry road conditions. Only
winter tyres displaying the 004Dsnowflake
symbol in addition to the M+S markin gpro-
vide optimum grip in wintry road conditions.
Only these tyres will allow the ABS and ESP
driving systems to function optimally in win-
ter, as these tyres have been designed spe-
cifically for driving on snow.
Use winter tyres of the same make and tread
on all wheels to maintain safe handling char-
acteristics. G
Risk of accident
Winter tyres with atread depth of less than
4mmm ust be replaced immediately. They are
no longer suitable for winter use and can no
longer provide sufficient grip. This could
cause you to lose control of your vehicle and
cause an accident.
Always observe the maximum permissible
speed specified for the winter tyres you have
fitted. If you fit winter tyres which have a
lower maximum permissible speed than that
of the vehicle, affix an appropriate warning
sign in the driver's field of vision. This can be
obtained at aqualified specialist workshop,
e.g. from aMercedes-Benz Servic eCentre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanen tSpeedtronic 37
to the maxi-
mum permissible speed for the winter tyres
(Y page 135).
