message is shown instead of the tyre pressure
display. The tyre pressures are already being
monitored.
After an emergency spare wheel has been fitted,
the system may still display the tyre pressure of the removed wheel for a few minutes. If this
occurs, note that the value displayed for the
position where the spare wheel is fitted is not
the same as the current tyre pressure of the
emergency spare wheel.
Warning messages of the tyre pressure monitor If the tyre pressure monitor detects a pressure
loss in one or more tyres, a warning message is
shown in the multifunction display. The yellow
tyre pressure warning lamp then lights up:
R If the Please correct tyre pressure
Please correct tyre pressure
message appears in the multifunction display,
the tyre pressure in at least one tyre is too
low. The tyre pressure must be corrected
when the opportunity arises.

Observe the instructions and safety notes in the display messages in the "Tyres" section
(Y page 239).
If the position of the wheels on the vehicle is
changed, the tyre pressures may be displayed in the wrong positions for a short time. After a few
minutes of driving, this is rectified and the tyre
pressures are displayed in the correct positions.
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 cur-
rently set tyre pressures as the reference values for monitoring. In most cases, the tyre pressure
monitor will automatically detect the new refer- ence values after you have changed the tyre
pressure. However, you can also set reference
values manually as described here. The tyre
pressure monitor then monitors the new tyre
pressure values. X
Use the table on the inside of the fuel filler flap
to ensure that the tyre pressure is set cor-
rectly in all four tyres for the current operating conditions.
Also observe the notes in the section on tyre
pressures (Y page 313).

Wheel and tyre combinations
General notes
You can ask for information regarding permitted wheel/tyre combinations at a Mercedes-Benz
Service Centre.
You should regularly check the pressure of all
your tyres, including the emergency spare
wheel, particularly prior to long trips, and cor-
rect the pressure as necessary (Y page 313).
The value on the wheel is valid.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres and wheels
which have been approved by Mercedes-Benz specifically for your vehicle.
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
(tyres featuring run-flat characteristics)
R MO1 = Mercedes-Benz Original (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres may
only be used on wheels that have been spe-
cifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tested
and approved by Mercedes-Benz. Certain
characteristics, e.g. handling, vehicle noise
emissions or fuel consumption, may other-
wise be adversely affected. In addition, when
driving with a load, tyre dimension variations
could cause the tyres to come into contact
with the bodywork and axle components. This
could result in damage to the tyres or the
vehicle.
Mercedes-Benz accepts no liability for dam-
age resulting from the use of tyres, wheels or accessories other than those tested and
approved.
Further information about wheels, tyres and
approved combinations can be obtained from
any qualified specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommended by Mercedes-Benz, since previ-
ous damage cannot always be detected 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. !
Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll comfort and suspension comfort are reduced and therisk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommended tyre pressures for various
operating conditions can be found in the tyre
pressure table on the fuel filler flap. Further
information on tyre pressure (Y page 313).
Check tyre pressures regularly and only when
the tyres are cold.
Notes on the vehicle equipment – always fit the
vehicle:
R with tyres of the same size across an axle
(left/right)
R with the same type of tyre (summer tyres,
MOExtended tyres, winter tyres)
Exception: it is permissible to fit a different
type or make in the event of a flat tyre.
Observe the "MOExtended tyres (tyres with
run-flat characteristics)" section
(Y page 295).
Vehicles with MOExtended tyres are not equip-
ped with a TIREFIT kit at the factory. It is there-
fore recommended that you additionally equip
your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteristics, e.g. win-
ter tyres. A TIREFIT kit can be obtained from a
qualified specialist workshop. Emergency spare wheel

WARNING
The wheel/tyre dimensions and the tyre type of the spare wheel/emergency spare wheel
and the wheel to be replaced may differ. Fit-
ting a spare wheel/emergency spare wheel
may severely impair the driving characteris-
tics. There is a risk of accident.
To prevent hazardous situations:
R Adapt your driving style accordingly and
drive carefully.
R Never fit more than one spare wheel/emer-
gency spare wheel if the dimensions are
different to those of the wheel being
replaced. Emergency spare wheel

Fuel grade
!
Do not use diesel to refuel vehicles with a
petrol engine. Do not switch on the ignition if
you accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel system. Even small amounts of the wrong fuel can
result in damage to the fuel system and the
engine. Notify a qualified specialist workshop
and have the fuel tank and fuel lines drained
completely.
! Only refuel using unleaded petrol with at
least 95 RON, which conforms to the Euro-
pean standard EN 228 or E DIN or an equiva-
lent specification.
Fuel of this specification may contain up to
10% ethanol. Your vehicle is suitable for use
with E10 fuel. You may refuel your vehicle
using E10 fuel.
Fuel that does not conform to EN 228 can lead
to increased wear as well as damage to the
fuel system, engine and exhaust system.
! Only use the fuel recommended. Operating
the vehicle with other fuels can lead to dam-
age to the fuel system, engine and exhaust
system. 328

Do not use the following:
R E85 (petrol with 85% ethanol)
R E100 (100% ethanol)
R M15 (petrol with 15% methanol)
R M30 (petrol with 30% methanol)
R M85 (petrol with 85% methanol)
R M100 (100% methanol)
R petrol with additives containing metal
R diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle.
You will usually find information about the fuel
grade on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
CLA 200, CLA 250, CLA 250 4MATIC,
CLA 250 Sport, CLA 250 Sport 4MATIC: as a
temporary measure, if the recommended fuel is
not available, you may also use regular unleaded petrol with an octane rating of 93 RON.
All other models: as a temporary measure, if
the recommended fuel is not available, you may
also use regular unleaded petrol with an octane
rating of 91 RON. This may reduce engine per-
formance and increase fuel consumption. Avoid driving at full throttle and sudden acceleration.
Never refuel using fuel with a lower RON.
i In some countries, the available petrol may
not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours,
especially on short journeys. As soon as sul-
phur-free fuel (sulphur content < 10 ppm) is
used for refuelling, the odours are reduced.
Information on refuelling (Y page 153).
Mercedes-AMG vehicles ! Only refuel using super unleaded petrol with
at least 98 ROZ, that conforms to European
standard EN 228 or an equivalent specifica-
tion.
You can otherwise impair engine output or
damage the engine.
Fuel of this specification may contain up to
10% ethanol. Your vehicle is suitable for use

! As a temporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petrol with an octane rating of
95 RON. This may reduce engine perform- ance and increase fuel consumption. As much
as possible, avoid driving at full throttle.
! As a temporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petrol in emergencies with an
octane rating of 91 RON.
Doing so results in noticeably higher fuel con-
sumption, and the engine power output is
noticeably reduced. Avoid driving at full throt- tle.
If no fuel other than petrol with 91 RON or a
lower grade is available, you should have the
vehicle adapted to run on this fuel at a quali-
fied specialist workshop.
CLA 250 (only for certain countries).
! Only refuel using sulphur-free unleaded pet-
rol with at least 95 ROZ, that conforms to the
European standard EN 228 or E DIN or an
equivalent specification.
You could otherwise impair engine output or
damage the emission control system.
i In some countries, the available petrol may
not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours,
especially on short journeys. As soon as sul-
phur-free fuel (sulphur content < 10 ppm) is
used for refuelling, the odours are reduced.
Additives ! Operating the engine with fuel additives
added later can lead to engine failure. Do not mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue build-up. Petrol must only be
mixed with additives recommended by
Mercedes-Benz. Observe the instructions for
use in the product description. More informa- tion about recommended additives can be
obtained from any Mercedes-Benz Service
Centre.
Mercedes-Benz recommends that you use fuel
brands that have additives.
The quality of the fuel available in some coun-
tries may not be sufficient. Residue could build
up in the fuel injection system as a result. In this case, in consultation with a Mercedes-Benz Ser-vice Centre, the petrol should be mixed with the
cleaning additive recommended by Mercedes-
Benz. Always observe the notes and mixing
ratios specified on the container. Service products and filling capacities

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 a risk 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
conform to EN 590 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. Otherwise,
engine damage may occur.
! Vehicles with diesel particle filters:
in
countries outside the EU, only use low sulphur
Euro diesel with a sulphur content of under
50 ppm. Otherwise, the emission control sys- tem could be damaged.
! Vehicles without a diesel particle filte
r:
in countries where only diesel fuel with a high sulphur content 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 quali-
fied specialist workshop.
Usually you will find information about the fuel
grade on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
Information on refuelling (Y page 153).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 specifica-
tions outlined in EN 590. At unusually low out-
side temperatures, it is possible that the flow
characteristics of the diesel fuel could be insuf- ficient. Accordingly, diesel fuel from warmer
areas may not be suitable for operation in colder
climatic conditions.

properties and fuel types with low-tempera-
ture resistance can be obtained from oil com-
panies, e.g. at filling stations. Engine oil
General notes When handling engine oil, observe the important
safety notes on service products (Y page 327).
The quality of the engine oil is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils that correspond to the current tech-
nical standard.
Therefore, only Mercedes-Benz-approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any Mercedes- Benz Service Centre. Mercedes-Benz recom-
mends that you have the oil change carried out
at a qualified specialist workshop. Mercedes-
