incorrectly ,there is arisk of fire and explo-
sion.
You must avoi dfire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable,t he auxiliary heating before
refuelling. G
WARNING
Fuel sare poisonous and hazardous to health.
There is adange rofinjury.
Do not swallowf uel or let it come into contact
with skin, eyesorc lothing. Do not inhal efuel
vapours. Keep fuel sout of the reach of chil-
dren. If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected area sofskin
with water and soap immediately.
R If you get fuel in youre yes,rinse them thor-
oughlyw ith clean water immediately.S eek
immediate medica lattention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Electrostatic charge can cause sparks and
thereby ignite fuel vapours. There is arisk of
fire and explosion.
Always touch the vehicl ebody before opening
the fuel filler flap or touching the fuel pump 108

Do not get back into the vehicl eduring the refu-
elling process ;otherwise, electrostatic charge
could buil dupagain. G
WARNING
If yo umix 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-
heatu nnoticed. There is arisk of fire.
Never refue lwith petrol. Never add petrol to
diesel fuel.
! Do not use petrol to refue
lvehicles with a
diesel engine. Do not switch on the ignitio nif
you accidentally refue lwith the wrong fuel.
Otherwise, fuel can enter the fuel system.
Even smal lamounts of the wrong fuel could
result in damage to the fuel system and the
engine. The repair costs are high .Notify a
qualified specialist worksho pand have the
fuel tank and fuel lines drained completely.
! Overfilling the fuel tank coul
ddamage the
fuel system.
! Take care not to spil
lany fuel on painted
surfaces. You coul dotherwise damage the
paintwork.
! Use
afilter when adding fuel from afuel can.
The fuel lines and/or the fuel injection system coul dotherwise be blocked by particles from
the fuel can.
If you overfil lthe fuel tank, some fuel may spray
out when you remove the fuel pump nozzle.

The specified tightening torque is 130 Nm.
X Dismantle the pump lever.
X Push the jack piston back in and close the

X Use the nuts to secure the faulty wheel to the
spare wheel bracket (Y page 223).
X Stow the jack and the vehicle tools in the
vehicle again.
X Check the tyre pressure of the newly fitted
wheel and adjust it if necessary.
Observe the recommended tyre pressure
(Y page 238). If you are drivin
gwith the emergency spare
wheel fitted, the tyre pressure monitor cannot
function reliably.R estart the tyre pressure mon-
itor only once the defective wheel has been
replaced with anew wheel.
All fitted wheelsm ust be equipped with func-
tioning sensors for the tyre pressure monitor. Wheel and tyre combinations
You can ask for information regarding permitted
wheel/tyre combinations at aMercedes-Benz
Service Centre.
! For safety reasons, Mercedes-Benz recom-
mends that you only use tyres, wheels and
accessories which have been approved by
Mercedes-Benz for you rvehicle. These are
speciall yadapted to the various driving safety
systems, such as ABS or ESP ®
.
Only use the tyres, wheels and accessories
tested and recommende dbyMercedes-Benz.
Certain characteristics, such as handling,
vehicl enoise emissions, fuel consumption,
etc. may otherwise be adversely affected.
Other wheel sizes may caus ethe tyres to
come into contact with the vehicl ebody and
axle components, whe nunder load. This may
result in damage to the tyre or the vehicle.
Mercedes-Benz is not responsibl efor any
damage caused by using tyres, wheels or
accessories other than those recommended.
Informatio nontyres, wheels and permissible
combinations can be obtained at aqualified
specialist workshop.
! Retreaded tyres are neither tested nor rec-
ommende dbyMercedes-Benz, since previ-
ous damage cannot alwaysbed etected on
retreaded tyres. As aresult, Mercedes-Benz
cannot guarantee vehicl esafety if retreaded
tyres are fitted. Do not fit use dtyres if you
have no information about their previous
usage.
! Large wheels: the lower the section width
for acertain wheel size, the lower the ride
comfort is on poor road surfaces. Rol lcomfort
and suspension comfort are reduced and the risk of damage to the wheels and tyres as a
result of driving over obstacles increases.
The recommende dtyre pressures for various
operating conditions can be found on the tyre 246

WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel.W hen the engine is running,
components in the exhaust system may over-
heatu nnoticed. There is arisk of fire.
Never refue lwith 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 leadtoi ncreased wear
as wellasd amage 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.
! Vehiclesw
ith diesel particle filters: in
countries outside the EU, only use low sulphur
Euro diesel with asulphurc ontent of under
50 ppm. Otherwise, the emission control sys- tem could be damaged.
You will usually find information aboutt he fuel
quality on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
Information on refuelling (Y page 109).
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 suitablef or operation in colder
climatic conditions.
i Further information on country-specific fuel
properties and fuel types with low-tempera-
ture resistance can be obtained from oil com- panies, e.g. at filling stations. AdBlue
