Regular inspections of gas systems
First read and observe the introductory information and safety warn-
ings on page 106.
Every two years, the following inspections must be carried out:
›
Check solenoid valves on the gas tanks for proper function.
›
Check natural gas tank and lines for leaks and fixing, if necessary look for dam-
ages.
›
Check the condition of fuel filler cap, filler tube and sealing ring, clean sealing
ring if necessary.

Safe natural gas
First read and observe the introductory information and safety warn-
ings on page 106.
The safety concept of the natural gas system ensures safe operation. It is equip-
ped with the following security features.
›
At each natural gas tank, there is a solenoid valve that closes automatically af-
ter turning off the ignition or when running in petrol mode.
›
A thermal fuse prevents uncontrolled rise in pressure in the natural gas tank in
case of fire.
›
A flow limiter prevents sudden emptying of the natural gas tank in case the
pressure system is damaged.
›
All the attachment points and materials are designed for maximum safety.

Natural gas quality and consumption
First read and observe the introductory information and safety warn-
ings on page 106.
Natural gas is divided into quality groups H-gas and L-gas. The two types of gas
are subdivided according to their calorific value and nitrogen and carbon dioxide
contents. H-gas has a higher calorific value and lower nitrogen or carbon dioxide
content than L-gas.

The higher the calorific value of natural gas, the lower is the consumption. How-
ever, the calorific value and the nitrogen and carbon dioxide contents can vary
within a quality group. Therefore, the consumption of the vehicle may even vary
when driving with only one natural gas quality (either only H-gas or L-gas).
The engine control of your vehicle automatically adjusts to the different natural
gas qualities. Therefore both natural gas qualities can be mixed in the fuel tank. It
is therefore not necessary to run the natural gas tank completely empty to fill up
another quality.
