comes into direct contact with fuels or you
breathe in fuel vapours. G
Risk of fire
Do not use petrol to refuel vehicles with adie-
sel engine. Never mix diesel with petrol. This
causes damage to the fuel system and engine
and could result in the vehicle catching fire.
! Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with apetrol engine. Even asmall
quantity of th ewrong fue lwill damage the
fuel system and engine.
! If the wrong fuel has been added by mis-
take, do not switch on the ignition .Ifyou
do, the fuel coul denter the fuel lines .The
fuel tan kand the fuel lines must then be
drained .Inform aqualified specialist work-
sho pand have the fuel tank and the fuel
lines drained comple tely. Petrol (EN 228)
Fuel grade !
Only refuel using unleaded premium-
grade petrol with at least
95 RON/8 5MON, whic hconforms to Euro-
pean standar dEN2 28.
Yo uc an otherwise impair engine output or
damage the engine.
! Do not use the following:
R E85 (petrol with 85 %ethanol)
R E10 0(100 %ethanol)
R M15 (petro lwith 15 %methanol)
R M85 (petrol with 85 %methanol)
R M10 0(100 %methanol)
R diesel
Do not mix these fuel swith petrol and do
not use any special additives. Otherwise,
this can lead to damage to the engine. This
does not include additives for the removal and prevention of residue build-up on the
inlet valves.
i If the recommended fuel is not available,
but only as atemporary measure, you may
also use regula runleaded petrol,
91 RON/82.5 MON. Thi smay reduce
engine performance and increase fuel con-
sumption. Avoid driv ingatf ull throttle.
In some countries, the fuel grad eavail able
may not be adequate and could cause res-
idu etob uild up around the inlet valve. In
such cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz (part no.
A000989254510). You must observe the
note sand mixing ratios specified on the
container.
For further information on "Fuel" ,see
(Y page 313). Diesel (EN 590, DIN 51628)
Fuel grade !
Only refuel with diesel that conform sto
Europea nstandard EN 590 or German
standard DIN 5162 8orthe equivalent. You
can otherwise impair engin eoutput or dam-
age the engine.
! Vehicles with diesel particle filters: in
countries outsid ethe EU ,only use low sul-
phu rEuro diesel with asulphu rcontent of
under 50 ppm. Otherwise, the emission
con trol system coul dbedamaged.
! Vehicles without adiesel particle fil-
ter: the engin eoil should be changed more
frequently in countries in which diesel with
ah igher sulphur conten tisavailable .More
information about intervals for changing
the engin eoil can be obtained from any
Mercedes-Benz Service Centre.

For further information on "Fuel", see
(Y page 313).
Low outsid etemperatures Diesel fuel with improved cold flow qualities
is available during the winter months. In
Europe, various climate-dependent low-tem-
perature classes are defined in EN 590. Refu-
elling with diesel fuel which complies with the
climatic specification sofstandard EN 590
can hel ptoprevent operatin gproblems. At
exceptionall ylow tempera tures, it is possible
that the flow properties of the fuel ma ybe
inadequate. This is also the case for fuel that
has not been adapted to the climatic specifi-
cations ,e.g. diese lfuel for warmer areas.
i Further information about country-spe-
cific fuel properties can be obtained from
oil companies, e.g. at filling stations.
Flow improver Flow improvers can be added to improve the
cold resistance of diesel fuel. The effective- ness of
aflow improver is not guaranteed with
every fuel.
Correc tdosage and thorough mixing ar edeci-
sive factor sinensuring improvement in low-
temperature resistance. Under certain cir-
cumstances, an excessive dosage may
actually decreas elow-temperatur eresist-
anc eand should therefor ebeavoided. Follow
th em anufacturer's dosing instructions.
Mix the additive with the diese ling ood time,
befor ethe flo wproperties of th ediesel
become inadequate. Malfunction scan other-
wise only be rectified by heating the entire
fuel system, e.g. by parking the vehicle in a
heated garage.
Observe the information provided by the man-
ufacturer when using aflow improver. Only
use flow improvers that have been tested and
approved by Mercedes-Benz. You can obtain

Snow chains For safety reasons
,Mercedes-Benz recom-
mends that you only use snow chain swhich
hav ebeen speciall yapproved for your vehicle
by Mercedes-Benz ,ora re of acorresponding
standar dofquality.
If you intend to fit snow chains, pleas ebear
the following point sinmind:
R you may not attac hsnow chains to all
wheel-tyre combinations ;see the "Tyres
and wheels" section in the "Techni caldata"
chapter.
R snow chains must not be fitted to emer-
gency spare wheels ,e.g. a"Minispare"
emergency spar ewheel.
R fit snow chains only in pair sand only to the
rear wheels .Observ ethe manufacturer's
installation instructions.
Do not exceed the maximum permissible
speed of 50 km /h.
i You may wish to deactivat eESP®
when
pulling away with snow chains fitted
(Y page 57). This way you can allow the
wheels to spin in acontrolled manner, ach-
ieving an inc reased driving forc e(cutting
actio n).
Slipper yroad surfaces G
Risk of accident
Do not shift down for additional engine brak-
ing on aslippery road surface. This could cause the drive wheels to lose their grip and
the vehicle could skid.
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudden accelera-
tion ,steering and braking manoeuvres.
If the vehicle threatens to skid or cannot be
stopped when movin gatlow speed:
X Vehicles with manua ltransmission: engage
neutral.
X Vehicles wit hautomatic transmission: shift
the transmission to position N.
X Try to bring the vehicle under control using
corrective steering.

Gen
eral information i
When towing atrail er,s et the tyr epres-
sure on th erear axle of the towing vehicle
for am aximum load; se ethe tyr epressure
table in th efuel filler flap.
You will find installatio ndimensions and loads
in the "Technical data” section
(Y page 322).
The maximum permissible trailer drawbar
noseweight on the ball coupling is 75 kg.
However ,the actual noseweight must not
exceed the value given on the trailer tow hitch
and trailer identification plates. The lowest
weight applies.
! Use anoseweight as close as possible to
the maximum permissible noseweight .Do
not use anoseweight of less than 50 kg,
otherwise the trailer ma ycome loose.
Bear in min dthat the payload and the rear
axl eload ar ereduced by the actual nose-
weight.
Please not ethat when towing atrailer, PARK-
TRONIC (Y page 174) and parkin gguidance
(Y page 177 )are onl yavail ablew ith limita-
tions, or not at all.
i The height of the ball coupling changes
with the load of the vehicle. If necessary,
use atrailer wit haheight-adjustable draw-
bar.
Driving tips i
Observ ethe notes on ESP ®
trailer stabi-
lisation (Y page 58).
In Germany, the maximum permissible speed
for vehicle/ trailer combinations depends on
the type of trailer and is either 80 km/ hor
100 km/h. In some countries ,higher maxi-
mum speeds are permissible for vehicle/
trailer combinations. Befor ebeginnin gthe
journey ,check the trailer's documen tsto see
what the maximum permitted speed is.
For certain Mercedes-Benz vehicles, the max-
imum permissible rear axle load is increased
when towing atrailer. Refer to th e"Technical data
"section to fin dout whether this applies
to your vehicle. If you utilise any of the added
maximum rear axle load when towing atrailer,
th ev ehicle/ trailer combination may not
exceed amaximum spee dof100 km/h for
reasons concerning the operating permit.
This als oapplies in countries in which the
permissible maximum speed for vehicle/
trailer combinations is above 10 0km/h.
When towing atrailer, your vehicle's handling
characteristics wil lbedifferent in comparison
to when drivin gwithout atrailer.
Th ev ehicle/ trailer combination:
R is heavier
R is restricted in its acceleration and gradi-
ent-climbin gcapability
R has an increased braking distance
R is affected more by stron gcrosswinds
R demand smore sensitive steering
R consume smore fuel
On long and steep downhil lgradients ,you
must shift to alower gear in good time, or on
vehicles with automatic transmission ,select
the shift range 1,2or 3.
i This also applies if you have activated
cruise control, SPEEDTRONIC or DI S-
TRONIC PLUS.
This will use the brakin geffect of th eengine,
so les sbraking wil lberequired to maintain
the speed. This relieves the load on the brake
system and prevent sthe brakes from over-
heating and wearing too quickly .Ifyou need
additional braking, depress the brake pedal
repeatedly rather than con tinuously.
Driving tips R
Maintain agreater distance from th evehi-
cle in front than when driving without a
trailer.
R Avoid braking abruptly. If possible, brake
gently at first to allow the trailer to run on.
Then increase the braking force rapidly.
R The values given for gradient-climbing
capabilities from astandstill refer to sea 188
