If the vehicle is parked directly after a refuelling operation, 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 gas tank after refuelling.
The maximum lifetime of the gas tank is 20 years.
The capacity of the natural gas fuel tank is approximately 15 kg.
WARNING
Natural gas is highly explosive and highly flammable.
■
When refuelling, never get into the vehicle. If you have to get into your
■
vehicle in exceptional cases, touch a metal surface before you touch the fill-
ing coupling again. Otherwise, electrostatic discharging may occur - There
is a risk of fire!
CAUTION
LNG (Liquefied Natural Gas), LPG (Liquefied Petroleum Gas) and hythane (mix-
ture of hydrogen and methane) must not be used - there is a risk of damaging
the engine and the exhaust system.
Note
During the filling process sounds are heard which are harmless. If you are un-
sure which service station staff to use, ask the petrol station staff.

Automatic switching from natural gas to petrol operation - Automatic
switching from natural gas to petrol operation takes place in the following sit-
uations (examples).
With an empty gas tank or not enough pressure in the tank.

▶
After refuelling with natural gas.
▶
At very low surrounding temperatures.
Every six months, to ensure the correct functioning of the fuel system, the fuel
tank for petrol should be run down until the warning light
Gas leak
If a gas leak is suspected (noticeable odour), proceed as follows.
▶
Stop the vehicle.
Switch off the ignition.
▶
Extinguish cigarettes, switch off spark-producing or incendiary items and re-
▶
move them from the vehicle.
▶
Open the doors and the boot lid to ventilate the vehicle 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, garage, ferry etc.), call the emergency services imme-
diately.
Seek help from a specialist garage to correct the gas system fault.
In a traffic accident
If a gas leak is suspected in a traffic accident, proceed as follows.
Switch off the ignition.
▶
▶
Extinguish cigarettes, switch off spark-producing or incendiary items and re-
move them from the vehicle.
▶
Have all the occupants get out.
▶
Keep all persons away from the vehicle. We recommend standing at least 10
metres from the vehicle.
Inform the emergency services that it is a natural gas vehicle.
▶
Regular gas system checks
Regular gas system checks must be carried out in a specialist workshop on
natural gas-powered vehicles. The vehicle owner is responsible for ensuring
tests are conducted properly.
