Refuelling
156which conforms to European standard
EN 228 or German standard DIN 51626-1.
You could otherwise 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 premium unleaded petrol,
95 RON/85 MON. This may reduce engine
performance and increase fuel consump-
tion. You must avoid driving at full throttle.
! 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 considerably higher petrol
consumption and significantly reduced per-
formance. Avoid driving at full throttle, and
only drive in drive program C.
If no fuel other than regular petrol fuel
91 RON/82.5 MO Nor a lower grade is per-
manently available, you should have the
vehicle adapted to run on this fuel by the
local after-sales service. Diesel (EN 590, DIN 51628)
! Refuel using only Diesel which conforms
to European standard EN 590 or German
standard DIN 51628.
You could otherwise impair engine output
or damage the engine.
You will find further information about die-
sel under "Fuel" in the index.
! When refuelling vehicles with a diesel par-
ticulate filter in countries outside the EU,
only low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
(50 ppm) should be used. In countries in
which diesel with a higher sulphur content
is available (e.g. 0.035 percent by weight),
the engine oil should be renewed at more
frequent intervals. More information about
intervals for changing the engine oil can be
obtained from any Mercedes-Benz Service
Centre.
! The use of fuels which do not meet the
requirements of EN 590 or German stand-
ard DIN 51628 can cause increased wear,
and damage the engine and the 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 add such fuels to diesel fuel and do
not use any special additives (exception:
flow improvers – see "Low outside temper-
atures").
Damage caused by the use of unapproved
fuels or additives is not covered by the war-
ranty.
Low outside temperatures The flow properties of diesel may be insuffi-
cient at low ambient temperatures.
To prevent operating problems, diesel fuel
with improved cold flow qualities is available
during the winter months. Your vehicle must
be refuelled with this winter diesel at temper-
atures of -5 °C or below.
You can use this winter diesel at tempera-
tures down to about -20 °C without problems.Operation

Tyres and wheels
163
!
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
If wheels or tyres other than those which
have been tested are fitted:
R the brakes or chassis components could
be damaged.
R wheel and tyre clearances can no longer
be guaranteed.
This could cause an accident.
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 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).
! 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, bumps on tyres and deforma-
tion, cracks or severe corrosion on wheels),
at least every 14 days, as well as after driv-
ing off-road or on rough roads. Damaged
wheels could 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 164). 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.
R regularly check the pressure of all your
tyres including the spare tyre, particularly
prior to long trips, and correct the pressure
as necessary (Y page 164).
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 a tyre is defective, Operation

Coolant
The coolant is a mixture of water and anti-
freeze/corrosion inhibitor. It performs the
following tasks:
R anti-corrosion protection
R antifreeze protection
R raising the boiling point
i When the vehicle is first delivered, it is
topped up with a coolant that will ensure
adequate antifreeze and corrosion protec-
tion.
! Only top up with coolant that has been
premixed with the desired antifreeze pro-
tection. You could otherwise damage the
engine.
There is more information about coolant
and topping it up on Mercedes-Benz Spec- ifications for Service Products Sheet
310.1.
! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low.
If antifreeze/corrosion inhibitor is present in
the correct concentration, the boiling point of
the coolant will be around 130 °C.
The antifreeze/corrosion inhibitor concentra-
tion in the cooling system should:
R be at least 50%. This will protect the cooling
system against freezing down to around
–37 °C.
R not exceed 55% concentration (antifreeze
protection down to –45 °C), otherwise heat
will not be effectively dissipated. If the vehicle has lost coolant, top it up with
equal amounts of water and antifreeze/cor-
rosion inhibitor. Mercedes-Benz recom-
mends using an antifreeze/corrosion inhibi-
tor which has been approved for Mercedes-
Benz vehicles.
! The cooling system contains a filling
which must be renewed after 15 years, or
after 250,000 km at the latest. Have the
renewal confirmed in the Service Booklet.
The warranty is only valid if you top up with
an antifreeze/corrosion inhibitor which
has been approved by Mercedes-Benz, and
observe the recommended mixing ratios. Technical data
