CAUTION
Petrol additives (additives)
Unleaded petrol complying with the EN 228 standard
■
tions for problem-free engine operation. We therefore do not recommend mix-
ing fuel additives into the petrol - risk of engine damage or damage to the ex-
haust system.
The following additives may not be used - risk of engine damage or damage
■
to the exhaust system!
Additives with metal components (metallic additives), in particular with
■
manganese and iron content.
Fuels with metallic content (e.g. LRP - lead replacement petrol).
■
Note
Unleaded petrol that has a higher octane number than that required by the
■
engine can be used without limitations.
On vehicles using the prescribed unleaded petrol of min. 95 RON, the use of
■
petrol with a higher octane number than 95 RON can lead to an increase in
power and reduction in fuel consumption.
Refuelling with CNG (compressed natural gas)

Read and observe and
Natural gas refuelling may vary from station to station. When refuelling with
natural gas at a station unfamiliar to you, you should get someone to instruct
you or allow the fuelling operation carried out by the station staff.

place.
The natural gas refuelling systems have an overfill protection relating to the
outdoor temperature. At very high outside temperatures, it may happen that
the gas tank may not be fully refuelled.
If the car 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 about 11 kg, of which about 1.5 kg
are in the reserve tank.
The capacity of the petrol fuel tank is approximately 10 litres, of which about 5
litres is in the reserve tank.
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
filling coupling again. Otherwise, electrostatic discharging may occur - risk
of fire!
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.
