to petrol, for example, if the following situations oc-
cur.

Requirements for refuelling
✓ Vehicle unlocked.
✓ Ignition switched off.
Refilling
›
Open the tank flap.
Engine, exhaust system and fuel ›
fill up with gas
›
Remove the cap
A
from the natural gas
filler neck.
›
Plug the coupling of
the refuelling system
onto the filler neck and
start refuelling with
natural gas.
CNG (compressed natural gas)
The refuelling system stops the refuelling process
automatically when the tank is full.
›
Place the cap on the filler neck.
›
Close the tank flap and click into place.
The natural gas refuelling systems have an overfill
protection with a dependence to the outdoor tem-
perature. With very high outside temperatures, it
may not be possible to fully refuel the natural gas
tank.
If the car is parked directly after a refuelling op-
eration, on restart the pointer of the gas gauge may
not show exactly the same level as immediately after
the filling process. This is not a leak in the system,
but a reduction in pressure due to the cooling of the
gas in the natural gas container after refuelling.
Troubleshooting
Unknown refuelling system
Natural gas refuelling may vary from station to sta-
tion. If refuelling with natural gas at a station is unfa-
miliar to you, get someone to instruct you or allow
the fuelling operation to be carried out by the station
staff.
Gas leakage
If a gas leak is suspected (perceptible odour), pro-
ceed as follows.
›
Stop the vehicle.
›
Switch off the ignition.
›
Extinguish cigarettes, switch off spark-producing
or incendiary items and remove them from the ve-
hicle.
›
Open doors and the boot lid to ventilate the vehi-
cle sufficiently.
›
Do not continue to drive if the odour persists.
›
If it is not possible to drive a vehicle with a gas leak
out of an enclosed area (e.g. tunnel, underpass, ga-
rage, ferry etc.), call the emergency services imme-
diately.
›
Ensure a gas system test is carried out immediately
by a specialist company.
