! Refuel using only unleaded super grade
petrol with a minimum octane number of
98 RON/88 MON conforming to European
standard EN 228.
Otherwise, you could impair engine output
or damage the engine.
i If the recommended fuel is not available
and only as a temporary measure, you may
also use unleaded premium-grade petrol,
95 RON/85 MON. This may reduce engine performance and increase fuel consump-
tion. Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause cok-
ing around the inlet valve. In such cases,
and in consultation with
aMercedes-Benz
Service Centre, the petrol may be mixed
with the additive recommended by
Mercedes-Benz( part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
! In emergencies, and only when the rec-
ommended fuel is not available, you may
also use standard unleaded petrol,
91 RON/82.5 MON.
However, using this fuel results in consid-
erably higher petrol consumption and sig-
nificantly reduced engine output. Avoid
driving at full throttle.
If no fuel other than regular petrol with
91 RON/82.5 MON or a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel by the
local after-sales service.
You can find further information about fuel on

wheels which have been approved by
Mercedes-Ben
zspecifically for your vehi-
cle. These tyres have been specially adap-
ted for use with the driving safety systems,
such as ABS or ESP ®
.Ify ou use other tyres
and wheels, Mercedes-Benz cannot accept
any responsibility for damage that may
result from this. Further information about
tyres, wheels and approved combinations
can be obtained from any Mercedes-Benz
Service Centre.
If you use tyres other than those tested and
recommended for Mercedes-Benz vehi-
cles, characteristics such as handling, vehi-
cle noise emissions and fuel consumption
may be adversely affected. In addition, the
wheels may come into contact with the
body or axle components when heavily loa-
ded or when driving with snow chains. This
could result in damage to the tyres or the
vehicle.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicle
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage. G
Risk of accident
Tyres, wheels or accessories which have not
been approved by Mercedes-Benz for your
vehicle or are not used as they should be, can
impair driving safety. As a result, you could
cause an accident .Before purchasing and
using them, enquire about their suitability,
legal stipulations and factory recommenda-
tions at a Mercedes-Benz Service Centre.
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle. Notes on selecting, fitting and replacing
tyres R
Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fitting new tyres, run them in at mod-
erate speeds for the first 100 km as they
only reach their full performance after this
distance.
R Fit new tyres on the front wheels first if
tyres of the same size are required on the
fron tand rea rwheels.
R Replace the tyres after six years at the lat-
est, regardless of wear. This also applies to
the collapsible emergency spare wheel* 17
.
R Do not drive with tyres which have too little
tread depth, as this significantly reduces
the traction on wet roads (aquaplaning).
! Store tyres 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,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or on rough roads. Damaged
wheels can cause a loss 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 272). 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 a valve cap to protect
the valve against dirt and moisture. Do not
fit anything onto the 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 You should regularly check the pressure of
all your tyres, particularly prior to long trips,
and correct the pressure as necessary
(Y page 272).
Notes on driving R
While driving, pay attentio nto 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 a tyre is defective,
reduce your speed immediately. 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 damage, have the wheels and tyres
examined at a specialist workshop, for
example at a Mercedes-Benz Service
Centre.
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 a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the tyre wall indicates its correct
direction of rotation. 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 a tyre 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 steering wheel so that you can see
the tyre tread more easily.
You could otherwise lose control of the vehi-
cle and cause an acciden tdue to the reduced
grip of the tyres on the road. Tyre pressures
i You will find a table of tyre pressures for
various operating conditions on the inside
of your vehicle's fuel fille rflap.
The value specified in the technical data is
valid for the collapsible emergency spare
wheel* 18
. G
Risk of accident
Tyre pressure that is either too high or too low
has a negative effect on vehicle safety, which
could lead you to cause an accident .There-
fore, you should regularly check the pressure
of all the tyres, particularly prior to long trips,
and correct the pressure as necessary.
Use a suitable tyre pressure gauge to do this.
The outer appearance of a tyre does not per-
mit any reliable conclusion about the tyre
pressure. You can also check the tyre pres-
sure using the on-board computer.

G
Risk of accident
Do not fit anything else to the tyre valve other
than the standard valve cap .Inparticular, ret-
rofitted tyre pressure monitors which are
screwed on to the valve may overload it and
cause it to fail. Due to their design, the valve
is kept open continuously, which may lead to
air loss. G
Ris
kofa ccident
Should the tyre pressure drop repeatedly:
R check the tyre for foreign bodies.
R check whether the wheel is losing air or the
valve is leaking.
R make sure that only a valve cap approved
by Mercedes-Ben zhas been fitted on the
tyre valve.
Tyre pressures that are to olow have a nega-
tive effect on vehicle safety, which could lead
to your causing an accident.
If possible, you should only correc ttyre pres-
sures when the tyres are cold. Depending on
the ambien ttemperature, the speed you are
driving at and the load on the tyres, the tyre
temperature and thus the tyre pressure may
change by approximately 0.1 bar per 10 †.
Take this into account when checking the
pressure of warm tyres and only correct it if
it is too low for the current operating condi-
tions.
Driving with tyre pressure that is too high or
too low can:
R shorten the service life of the tyres
R cause increased tyre damage
R have a negative effec tonhandling charac-
teristics and thus the driving safety (e.g. by
causing aquaplaning) H
Environmental note
Chec kthe tyre pressure regularly, at least
every 14 days. Tyre pressure monitor
If a tyre pressure monitor system is fitted, the
vehicle's wheels have sensors fitted that
monitor the tyre pressures in all four tyres.
The tyre pressure monitor warns you when
the pressure drops in one or more of the
tyres. The tyre pressure monitor only func-
tions if the correct wheel electronics units are
fitted to all wheels. G
Risk of accident
The tyre pressure monitor does not warn you
of an incorrectly set tyre pressure. The table
on the inside of the fuel filler flap will help you
decide whether the tyre pressures should be
corrected.
The tyre pressure monitor is not able to warn
you of a sudden loss of pressure, e.g. if the
tyre is penetrated by a foreign object. In the
event of a sudden loss of pressure, bring the
vehicle to a halt by braking carefully. Do not
make any sudden steering movements when
doing so.
i The operation of the tyre pressure moni-
tor can be affected by interference from
radio transmitting equipment (e.g. radio
headphones, two-way radios) that may be
being operated in or near the vehicle.

The tyre pressure values indicated by the
on-board computer may differ from those
measured at a filling station with a pressure
gauge.T he tyre pressures shown by the on-
board computer refer to those measured at
sea level. At high altitudes, the tyre pres-
sure values indicated by a pressure gauge
are higher than those shown by the on-
board computer. In this case, do not reduce
the tyre pressures.
i After a teach-in period, the tyre pressure
monitor automatically recognises new
wheels or new sensors. As long as a clear
allocation of the tyre pressure values to the
individual wheels is not possible, the Tyre

Restarting the tyre pressure monitor When you restart the tyre pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tyre pressures as the speci-
fied values for monitoring.

minutes of driving, and the tyre pressures
are displayed for the correct positions.
Interchanging the wheels
G
Risk of accident
Interchange the front and rear wheels only if
they have the same dimensions: for example
size, offset, etc.
After every wheel interchange/change, have
the tightening torque checked at a qualified
specialist workshop that has the necessary
specialist knowledge and tools to carry out
the work required. Mercedes-Benz recom-
mends that you use a Mercedes-Benz Service
Centre for this purpose. In particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop.
The wheels could work loose if they are not
tightened to a torque of 130 Nm.
For safety reasons, Mercedes-Benz recom-
mends that you only use wheel bolts of the
correct size which have been approved for
Mercedes-Benz vehicles.
The wear patterns on the front and rear tyres
differ, depending on the operating conditions.
Interchange the wheels before a clear wear
pattern has formed on the tyres. Front tyres
typically wear more on the tyre shoulders and
the rear tyres in the centre.
On vehicles that have the same size front and
rear wheels, you can interchange the wheels
every 5000 km to 10,000 km depending on
the degree of tyre wear. Do not reverse the
direction of tyre rotation.
Cleant he contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is interchanged. Check the tyre pressure and
reactivate the tyre pressure monitor if neces-
sary.
! As your vehicle is fitted with a tyre pres-
sure monitor, electronic components are
located in the wheel. Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the wheels interchanged/
changed at a qualified specialist workshop,
e.g. a Mercedes-Benz Service Centre.
Winter operation
Please bear the following in mind
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at a Mercedes-Benz
Service Centre, at the onset of winter.
Observe the notes in the "Changing a wheel"
section (Y page 275). Winter tyres
Use winter tyres at temperatures below
+7 ˚C and in wintry road conditions. Only
winter tyres displaying the 0001snowflake
symbol in addition to the M+S marking pro-
vide optimum grip in wintry road conditions.
Only these tyres will allow the ABS and
ESP ®
driving safety systems to function opti-
mally in winter, as these tyres have been
designed specifically 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 a tread depth of less than
4mmm ust be replace dimmediately. They are
no longer suitable for winter use and can no
longer provide sufficient grip. This could
cause you to lose control of yourv ehicle 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 Winter operation

obtained at a qualified specialist workshop,
e.g. from a Mercedes-Benz Service Centre.
Under these circumstances, you should also
restrict the maximum speed of the vehicle
using permanent SPEED-
TRONIC 19
(Y page 245) so that it does not
exceed the maximum permissible speed for
the winter tyres.
Once you have fitted the winter tyres:
X Check the tyre pressures (Y page 272).
X Restart the tyre pressure monitor
(Y page 273).
i Speeds of up to 240 km/h with winter
tyre variant 1: despite what is stated on the
tyre pressure information label (fuel filler
flap), for speeds up to 240 km/ha nd winter
tyre variant 1 (Y page 354), the tyre pres-
sures can be reduced:
R front −40 kPa (−0.4 bar)
R rear −60 kPa (−0.6 bar)
This improves the ride comfort of your vehi-
cle; however, the fuel consumption may
increase slightly. G
Ris
kofa ccident
If you fit the spare wheel* when driving with
winter tyres, bear in mind that driving stability
will be impaired owing to unstable cornering
characteristics caused by the differen ttyres.
You should therefore adapt your driving style
and drive carefully.
Have the spare wheel* replaced at the near-
est qualified specialist workshop which has
the necessary specialist knowledge and tools
to carry out the wor krequired. Mercedes-
Benz recommends that you use a Mercedes-
Benz Service Centre for this purpose. In par-
ticular, work relevant to safety or on safety-
related systems must be carried out at a quali-
fied specialist workshop. Snow chains
For safety reasons, Mercedes-Benz recom-
mends that you only use snow chains which
have been specially approved for your vehicle
by Mercedes-Benz, or are of a corresponding
standard of quality.
If you intend to fit snow chains, please bear
the following points in mind:
R snow chains cannot be fitted to all wheel/
tyre combinations.
R snow chains must not be fitted to emer-
gency spare wheels, e.g. Minispare.
R fit snow chains only in pairs and only to the
rear wheels. Observe the manufacturer's
installation instructions.
Do not exceed the maximum permissible
speed of 50 km/h.
i You may wish to deactivate ESP ®
when
pulling away with snow chains fitted
(Y page 47). This way you can allow the
wheels to spin in a controlled manner, ach-
ieving an increased driving force (cutting
action). Winter driving
G
Risk of accident
Do not shift down for additional engine brak-
ing on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion, steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when moving at low speed:
X Engage neutral.
X Try to bring the vehicle under control using
corrective steering.
