Checking and refilling levels
WARNING
Natural gas is a highly explosive, easily
flammable subst
ance. Incorrect handling
of the natural gas can cause accidents se-
rious burns and other injuries.
●
Before refuelling with natural gas, en-
gage the filling mouth correctly. If you can
smell gas, stop refuelling immediately.

in Natural gas
on page 328.
WARNING
The vehicle is not suitable for liquefied nat-
ural gas (LNG) or liquefied petrol gas (LPG),
so LNG or LPG shoul
d 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 ev
ent 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 nat
ural gas pumps
can differ in the way they are operated. Ask
a qualified employee at the petrol station
to do the refuelling if you do not know how.
●
Noises heard when refuelling are normal
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.
