WARNING
Natural gas is a highly explosive, easily
fl
ammable substance. Incorrect handling

gage the filling mouth correctly. If you can
smell gas, stop refuelling immediately.

Read and take note

in Natural gas
on page 322.
WARNING
The vehicle is not suitable for liquefied nat-
ur
al 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 se
vere injuries! .
WARNING
If the vehicle underbody touches the
gr
ound or in the event of a rear collision,
there could be damage to the natural gas
tanks. If damaged, natural gas tanks are
full of fuel and can explode, causing seri-
ous or fatal injuries.
●
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. Do not refuel natural gas
again until the natural gas system has been
inspected.
Note
●
The filling no
zzles of natural 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.
