If
at yre size precedes atyre pressure, the
following tyre pressure information is only
validf or that tyre size.
Use asuitable pressure gauge to check the
tyre pressure. The outer appearance of atyre
does not permit any reliable conclusion about the tyre pressure. On vehicle sfitted with the
electronic tyre pressure monitor, the tyre
pressure can be checked using the on-board
computer.
If possible, only correct tyre pressures when
the tyres are cold.
The tyres are cold:
R if the vehicle has been parked with the tyres
out of direct sunlight for at least three
hours and
R if the vehicle has not been driven further
than 1.6 km
Depending on the ambient temperature ,the
vehicle speed and the loadont he tyres, the
tyre temperature and thus the tyre pressure
changes by approximately 10 kPa (0. 1bar/
1.5 psi )per 10 †. Take this into account
when checking the pressure of warm tyres.
Only correct the tyre pressure if it is too low
for the current operating conditions.
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 anegative effect on handling charac-
teristics and thus driving safety (e.g. aqua-
planing) The tyre pressure values given for low loads
are minimum values which offer you good ride
comfort characteristics.
However, you can also use the values given
for higherl oads. These are permissible and
willn ot adversely affect the running of the
vehicle.
Speeds up to 210 km/h: despite the values
stated on the tyre pressure information label (fuel filler flap), for speedsupt o210 km/h
and with R16 tyres, the values stated can be
reduced as follows, withou tareduction in
safety:
R Saloon: Ò30 kPa (Ò0.3 bar/Ò4p si)
R Estate: Ò20 kPa (Ò0.2 bar/Ò3p si)
This does not apply to vehicle stowing a
trailer.
This improves the ride comfort of yourv ehi-
cle; however, fuel consumption may increase slightly. Tyre pressure lossw
arning system
General notes Whilet
he vehicle is in motion, the tyre pres-
sure loss warning system monitors the set
tyre pressure using the rotational speed of
the wheels. This enables the system to detect significant pressure loss in atyre. If the speed
of rotation of awhee lchanges as aresultofa
loss of pressure, acorresponding warning

! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These are specially adapted to the control
systems, such as ABS or ESP
®
and are
marked as follows:
R MO =Mercedes-Benz Original
R MOE =Mercedes-Benz Original Extended

R MO1 =Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz.C er-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components. This could result in dam- age to the tyres or the vehicle.
Mercedes-Benz accepts no liability for
damage resulting from the use of tyres,
wheels or accessories other than those tes-
ted and approved.
Further information about wheels, tyres

previous damage cannot alway sbedetec-
ted on retreaded tyres. As aresult,
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.

Mercedes-Ben
zrecommends that you use
fuel brands that have additives.
The quality of the fuel available in some coun- tries may not be sufficient. Residuec ould
build up in the injection system as aresult. In
this case, in consultation with aMercedes-
Benz Service Centre, the petrol may be mixed with the cleaning additive recommended by
Mercedes-Benz. Always observe the notes
and mixing ratios specified on the container.
Diesel Fuel grade
G
WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is arisk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590
or is of equivalent quality. Fuel that does
not conformtoEN5 90 can lead to
increased wear as well as damage to the
engine and exhaust system.
! Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and
do not use any special additives. Other-
wise, engine damage may occur.
! Vehicles with diesel particle filters:
in
countries outside the EU, only use low sul-
phur Euro diesel with asulphurc ontent of under 50 ppm
.Otherwise, the emission
control system could be damaged.
! Vehicles without
adiesel particle fil-
ter: in countries where only diesel fuel with
ah igh sulphurc ontent is available, you will
need to carry out your vehicle's oil change
at shorter intervals. More information
about the interval for oil change can be
obtained from any qualified specialist
workshop.
Usuallyy ou will find information about the
fuel grade on the pump. If you cannot find the
label on the petrol pump, ask the filling sta-
tion staff.
Information on refuelling (Y page 201).
Low outside temperatures
In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc- tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifi-
cations outlined in EN 590. At unusually low
outside temperatures, it is possible that the
flow characteristics of the diesel fuel could be insufficient .Accordingly, diesel fuel from
warmer areas may not be suitable for opera-
tion in colder climatic conditions.
i Further information on country-specific
fuel properties and fuel types with low-tem-
perature resistance can be obtained from
oil companies, e.g. at filling stations.
