i Vehicles with a diesel engine:
if the fuel tank has been run completely dry,
it will be necessary to bleed the fuel system
(Y page 232). 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.
i As a temporary measure, only when the
recommended fuel is not available, you
may also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the available petrol qual-
ity may not be adequate 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 specified on the
container.
For further information on "Fuel" see
(Y page 291). Turbo engines !
Refuel using only unleaded Super Plus
with a minimum octane number of
98 RON/88 MON conforming to European
standard EN 228.
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. 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 Operation

Driving ab
road 185Driving on wet roads
If water has accumulated to a certain depth
on the road surface, there is a danger of aqua-
planing occurring, even if:
R you drive at low speeds
R the tyres have adequate tread depth
For this reason, do not drive in tyre ruts, and
brake carefully. Driving on flooded roads
If you have to drive on stretches of road on
which water has collected, please bear in
mind that:
R the maximum permitted still water depth is
25 cm.
R you should drive no faster than at walking
pace.
! Bear in mind that vehicles travelling in
front or in the opposite direction create
waves. This may cause the maximum per-
missible water depth to be exceeded.
Failure to observe these notes may result
in damage to the engine, electrical systems
and transmission. Driving abroad
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 168). Symmetrical dipped beam
If your journey takes you to countries where
vehicles are driven on sides of the road oppo-
site to the country in which the vehicle is reg-
istered, your headlamps must be switched to
symmetrical dipped beam. Oncoming traffic
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
Remember to set the headlamps back to
asymmetrical dipped beam when you return to driving on the same side of the
road as that of the country in which your
vehicle was registered. You may otherwise
dazzle the oncoming traffic and could cause
an accident. Operation
