Checking and refilling levels
The vehicle is only prepared for refuelling
with Compressed Natural Gas (CNG) ››› . Re-
fuelling with another type of natural gas is
not allowed, e.g. Liquefied Nature Gas (LNG)
or hydromethane.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel
tank cap, next to the petrol filler mouth.

WARNING
Natural gas is a highly explosive, easily flam-
mable substance. Incorrect handling of the
natural gas can cause accidents serious
burns and other injuries.
●
Before refuelling with natural gas, the fill-
ing mouth must be correctly engaged. If you
can smell gas, stop refuelling immediately.
WARNING
The vehicle is not prepared to use liquefied
natural gas (LNG) and this fuel must not be
added under any circumstances. Liquefied
natural gas can cause the natural gas tank to
explode, resulting in serious injury.
Note
●
The filling nozzles of natural gas pumps
can differ in the way they are operated. If you
are unacquainted with the pump, it is advisa-
ble that a member of staff of the service sta-
tion performs the refuelling operation.
●
Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system.
●
The vehicle natural gas system is prepared
both for refuelling with a small compressor
(slow refuel) and a large compressor (fast re-
fuel) in natural gas service stations.
