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 r
efuelling with natural gas, en-
gage the filling mouth correctly. If you can
smell gas, stop refuelling immediately.
WARNING
The vehicle is not prepared to use liquefied
nat
ural gas (LNG), and this fuel must not be
added under any cir
cumstances. Liquefied
natural gas can cause the natural gas tank
to explode, resulting in serious injury.
Note
●
The filling nozzles of nat
ural gas pumps
can differ in the way they are operated. If
you do not know, ask a qualified employee
at the petrol station to do the refuelling.
●
Noises heard when refuelling are normal
and do not indicate the presence of a fault
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) in natural gas service sta-
tions.
