WARNING
Observe all relevant statutory regulations on
trans
porting spare fuel canisters. For safety
reasons, we do not recommend carrying a
spar
e canister in the vehicle. The canister
could be damaged in an accident and fuel
may leak. Risk of fire!
CAUTION
●
Sw
itc
h off the auxiliary heater (heater and
independent heater) before filling the tank.
●
The fuel tank is full as soon as the automat-
ic filler nozzle cuts out. Do not continue fill-
ing, as this will fill the expansion chamber.
●
Never completely empty the tank! An irreg-
ular fuel supply can cause ignition faults,
which can result in damage to a substantial
amount of engine parts and the exhaust sys-
tem.
●
If any fuel is spilt onto the paintwork of the
vehicle, it should be removed immediately.
Risk of damage to paintwork!
Note
The fuel tank capacity is around 55 litres, of
which 7 litre
s are the reserve.
Unleaded petrol
Your vehicle must only be run on u
n
l
eaded
petrol that complies with the Standard EN
228 (in Germany, also DIN 51626 – 1, or E10
for unleaded petrol with 95 and 91 octane
rating (RON) or DIN 51626 – 2, or E5 for un-
leaded petrol with 95 and 98 RON).
Prescribed fuel – unleaded petrol (95/91
RON)
Use unleaded petrol with 95 RON. Unleaded
petrol with 91 RON can also be used, al-
though this will result in a slight loss of pow-
er.
If, as an emergency measure, you have to fill
the tank with petrol with a lower RON to that
prescribed, use only moderate engine
speeds and light throttle. High engine speed
and full throttle can seriously damage the en-
gine! Fill up with petrol with the correct RON
as soon as possible.
Prescribed fuel – unleaded petrol (min. 95
RON)
Use unleaded petrol with 95 RON.
If unleaded petrol with 95 RON is not availa-
ble, you can fill up with petrol with 91 RON as
an emergency measure. In this case, use only
moderate engine speeds and a light throttle.
High engine speed and full throttle can seri-
ously damage the engine! Fill up with petrol
with the correct RON as soon as possible.
Petrol with a RON below 91 cannot be used,
even as an emergency measure. Risk of seri-
ously damaging the engine!
Unleaded petrol with higher RON
Unleaded petrol with a higher RON to that
prescribed can be used without limits.
