The vehicle is not suitable for liquefied nat-
ural gas (LNG) or liquefied petrol gas (LPG),
so LNG or LPG should not be used under
any circumstances. Liquid gas can cause
an explosion of the natural gas tanks and
cause severe injuries!.
CAUTION
If the vehicle underbody touches the
ground or in the event of a rear collision,
there could be damage to the natural gas
tanks.
Even if you don't notice the smell of gas,
●
take the vehicle to a specialised workshop
immediately and have the natural gas sys-
tem checked.

Note
The filling nozzles of natural gas pumps
●
can differ in the way they are operated. Ask

and do not indicate damage in the system.
The vehicle natural gas system is pre-
●
pared both for refuelling with a small com-
pressor (slow refuel) and a large compres-
sor (fast refuel) at natural gas service sta-
tions.

Fuel types

Fuels are identified by different symbols on
the pump and on your vehicle's tank flap. The
identification serves to prevent confusion
when choosing the fuel.
Petrol with ethanol ("E" stands for Etha-
1
nol). The number indicates the percent-
age of ethanol in the petrol. "E5" means,
for example, an ethanol ratio of 5% max.
Diesel with biodiesel ("B" stands for Bio-
2
diesel). The number indicates the per-
centage of biodiesel in the diesel. "B7"
