246Driving and operatingFuel for diesel engines
Only use diesel fuel that complies
with EN 590 and which has a sulphur
concentration of max. 10 ppm.
Fuels with a biodiesel (compliant with
EN 14214) content of max. 7% by
volume may be used (e.g. named
B7).
If travelling in countries outside the
European Union occasional use of Euro-Diesel fuel with a sulphur
concentration below 50 ppm is
possible.
Caution
Frequent usage of diesel fuel
containing more than 15 ppm
sulphur will cause severe engine
damage.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Low temperature operation At temperatures below 0 °C, some
diesel products with biodiesel blends may clog, freeze or gel, which mayaffect the fuel supply system. Starting
and engine operation may not work
properly. Make sure to fill winter
grade diesel fuel at ambient
temperatures below 0 °C.
Arctic grade diesel fuel can be used
in extreme cold temperatures below
-20 °C. Using this fuel grade in warm
or hot climates is not recommended
and may cause engine stalling, poor starting or damage on the fuel
injection system.
Refuelling9 Danger
Before refuelling, switch off
ignition and any external heaters
with combustion chambers.
Follow the operating and safety
instructions of the filling station
when refuelling.
Driving and operating2479Danger

sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
A label with symbols at the fuel filler
flap is indicating the allowed fuel
types. In Europe the pump nozzles of the filling stations are marked with
these symbols. Refuel only the
allowed fuel type.
Caution
In case of misfuelling, do not
switch on ignition.
Fuel filler flap is located at right rear
side of vehicle.
The fuel filler flap can only be opened
if the vehicle is unlocked. Release the
fuel filler flap by pushing the flap.
Petrol and Diesel refuelling

force to insert.
To refuel, switch on pump nozzle.
After the automatic cut-off, the tank can be topped up by operating the
pump nozzle a maximum of two more
times.Caution
Wipe off any overflowing fuel
immediately.
