i Vehicles with a diesel engine:
If the tank has been run completely dry, it
will be necessary to bleed the fuel system
(Y page 289). Petrol (EN 228)
! Refuel using only unleaded premium
grade petrol with a minimum octane num-
ber of 95 RON/85 MON conforming to
European standard EN 228.
You could otherwise impair engine output
or damage the engine.
You will find further information about pet-
rol under "Fuel" in the index.
i As a temporary measure, but only when
the recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce per-
formance and increase petrol consump-
tion. Avoid driving at full throttle.
In some countries, the available petrol qual-
ity may not be sufficient and could cause
coking 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
notes and mixing ratios given on the con-
tainer. Diesel (EN 590)
! Only use diesel that complies with the
EN 590 European standard.
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-
ticle filter in countries outside the EU, only
low-sulphur Euro diesel with less than
0.005 percent sulphur content by weight
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.
! Using fuel that does not comply with EN
590 can increase wear and damage the
engine and the exhaust system.

Points to remember
An extensive Mercedes-Benz Service network
is also available in other countries. The
Service Hotline's current telephone numbers
for use when you are abroad are to be found
in the "Service24h" chapter of the Service
Booklet.
Only low-octane fuel is available in certain
countries.
You can find further information about fuel
grades on (Y page 218). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on the opposite side of the
road to the country in which the vehicle is
registered, your headlamps must be switched
to symmetrical dipped beam. Oncoming traf-
fic will be dazzled less.
X Have the headlamps switched over at a
qualified specialist workshop, e. g. a
Mercedes-Benz Service Centre. G
Risk of accident
Have your headlamps switched back to
asymmetrical dipped beam if you visit a country in which traffic drives on the same
side of the road as in the country in which
your vehicle was registered. You may oth-
erwise dazzle the oncoming traffic and
could cause an accident. Trailer towing*
Fitting the ball coupling
Before you can tow a trailer with your vehicle,
you must fit the ball coupling.
There is a key for the ball coupling.
X Make a note of the key number.
You can use this number to obtain a
replacement key from a Mercedes-Benz
Service Centre. G
Risk of injury
If the ball coupling does not engage cor-
rectly when it is fitted, the vehicle/trailer
combination will not be properly secured
and may detach. This could cause an acci-
dent. Fit the ball coupling carefully and
make sure that it engages correctly.
The detachable ball coupling is located in the
stowage well under the luggage compartment
floor.
The ball coupling recess is behind the cover
at the bottom of the bumper. Operation
