RefuellingDriving and parking

!
Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
When reversing the vehicle towards the
trailer, make sure there is nobody between
the trailer and the vehicle.
Couple and uncouple the trailer carefully. If
you do not couple the trailer to the towing
vehicle correctly, the trailer could become
detached.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to when driving without a trailer.
The vehicle/trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbing capability
R has an increased braking distance
R is affected more by strong crosswinds
R demands more sensitive steering
R has a larger turning circle
This can impair the vehicle's handling char-
acteristics. Adapt your driving style accord-
ingly. Maintain a safe distance. Drive care-
fully.
When towing a trailer, always adjust your
speed to the current road and weather con-
ditions. Do not exceed the maximum permis- sible speed for your vehicle/trailer combina-
tion. Notes on towing a trailer
General notes Trailer towing is not permissible on the fol-
lowing models:
R C 180 BlueEFFICIENCY Edition
R C 220 BlueTEC BlueEFFICIENCY Edition
When towing a trailer, set the tyre pressure on
the rear axle of the towing vehicle for a max-
imum load; see the tyre pressure table in the fuel filler flap (Y page 432). On vehicles without level control, the height
of the ball coupling will alter according to the
load placed on the vehicle. If necessary, use a
trailer with a height-adjustable drawbar.
You will find fitting dimensions and loads
under "Technical data" (Y page 477).
When towing a trailer, the ECO start/stop
function is deactivated. The èECO sym-
bol appears yellow in the multifunction dis-
play. For further information on the ECO
start/stop function; see (Y page 186).
Driving tips Observe the notes on ESP
®
trailer stabilisa-
tion (Y page 82).
The maximum permissible speed for vehicle/ trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the max- imum permitted speed is. Observe the legally
prescribed maximum speed in the relevant
country.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing a trailer. See the "Technical
data" section to find out whether this applies
to your vehicle (Y page 478). If you utilise any
of the added maximum rear axle load when
towing a trailer, the vehicle/trailer combina-
tion may not exceed a maximum speed of
100 km/h for reasons concerning the oper-
ating permit. This also applies in countries in
which the permissible maximum speed for
vehicle/trailer combinations is above
100 km/h.
When towing a trailer, your vehicle's handling
characteristics will be different in comparison to when driving without a trailer and it will
consume more fuel.
Change into a lower gear in good time on long
and steep downhill gradients.
This also applies if cruise control, DISTRONIC
PLUS or SPEEDTRONIC are activated.
This will use the braking effect of the engine,
so less braking will be required to maintain
vehicle speed. This relieves the load on the 284

WARNING
If wheels and tyres of the wrong size are used, the wheel brakes or suspension components
may be damaged. There is a risk of an acci-
dent.
Always replace wheels and tyres with those
that fulfil the specifications of the original
part.
When replacing wheels, make sure to fit the
correct:
R designation
R type
When replacing tyres, make sure to fit the
correct:

WARNING
A flat tyre severely impairs the driving, steer-
ing and braking characteristics of the vehicle.
There is a risk of accident.
Tyres without run-flat characteristics:
R do not drive with a flat tyre.
R immediately replace the flat tyre with your
emergency spare wheel or spare wheel, or
consult a qualified specialist workshop. Tyres with run-flat characteristics:
R pay attention to the information and warn-
ing notices on MOExtended tyres (tyres
with run-flat characteristics).
Accessories that are not approved for your
vehicle by Mercedes-Benz or are not being
used correctly can impair the operating
safety.
Before purchasing and using non-approved
accessories, visit a qualified specialist work-
shop and enquire about:
R suitability
R legal stipulations
R factory recommendations
Information on the dimensions and types of
wheels and tyres for your vehicle can be
found under "Wheel/tyre combinations"
(Y page 444).
Information on air pressure for the tyres on
your vehicle can be found:
R on the tyre pressure label on the fuel filler
flap (Y page 202)
R under "Tyre pressure" (Y page 432)
Modification work on the brake system and
wheels is not permitted. The use of wheel
spacers or brake dust shields is not permit-
ted. This invalidates the general operating
permit for the vehicle.
i Further information on wheels and tyres
can be obtained at any qualified specialist
workshop. Operation
Information on driving
Check the tyre pressures when the vehicle is
heavily laden and, if necessary, adjust.
While driving, pay attention to vibrations,
noises and unusual handling characteristics,
e.g. pulling to one side. This may indicate that the wheels or tyres are damaged. If you sus-
pect that a tyre is defective, reduce your
speed immediately. Stop the vehicle as soon 428
OperationWheels and tyres

Wheel and tyre combinations
General notes
! 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
(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
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with a load, 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
and approved combinations can be
obtained from any qualified specialist
workshop.
! 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. !
Large wheels: the lower the section width
for a certain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as a result of driving over obstacles
increases.
Overview of abbreviations used in the follow-
ing tyre tables:
R BA: both axles
R FA: front axle
R RA: rear axle
You will find a table with recommended tyre
pressures for various operating conditions on
the inside of your vehicle's fuel filler flap. For
further information on tyre pressure, see
(Y page 432). 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 on a given axle
(left/right)
R with the same type of tyres at a given time
(summer tyres, winter tyres, MOExtended
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 408).
Vehicles with MOExtended tyres are not
equipped with a TIREFIT kit at the factory. It is
therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you fit tyres that do not feature run-flat characteris-
tics, e.g. winter tyres. A TIREFIT kit can be
obtained from a qualified specialist work-
shop.
i Not all wheel/tyre combinations can be
fitted at the factory in all countries. 444

at shorter intervals. More information
about the interval for oil change can be
obtained from any qualified 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 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.
Fuel consumption information H
Environmental note
CO 2(carbon dioxide) is the gas which scien-
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO 2emissions are directly related to
fuel consumption and therefore depend on:
R efficient use of the fuel by the engine
R driving style
R other non-technical factors, such as envi-
ronmental influences, road conditions or
traffic flow
You can minimise your vehicle's CO 2emis-
sions by driving carefully and having it serv-
iced regularly. The vehicle will use more fuel than usual in the
following situations:
R at very low outside temperatures
R in urban traffic
R on short journeys
R in mountainous terrain
R when towing a trailer
i Only for certain countries: you can find
the current consumption and emission val-
ues of your vehicle in the COC documents
(EU CERTIFICATE OF CONFORMITY). These documents are delivered with your vehicle.
The consumption figures were, in each
case, based on the currently applicable ver-sion:
R for vehicles that comply with standards
up to and including the EURO 4 standard, in accordance with EU Directive
80/1268/EEC
R for vehicles that comply with or exceed
the Euro 5 standard, in accordance with
Regulation (EC) No. 715/2007
Deviations from these values may occur
under normal operating conditions. AdBlue
®
Important safety notes AdBlue
®
is a water-soluble fluid for the
exhaust gas aftertreatment of diesel engines. It is:
R non-toxic
R colourless and odourless
R non-flammable
If you open the AdBlue ®
tank, small amounts
of ammonia vapour may be released.
Ammonia vapours have a pungent odour and
are particularly irritating to the skin, to
mucous membranes and to the eyes. You may experience a burning sensation in your eyes,
nose and throat. You may also experience
coughing and watery eyes. 472
