- Fig. 1 Instrument cluster: Gas fuel gauge
- Fig. 2 Display: Combined fuel warning for petrol and natural gas
Applies to vehicles: with natural gas engine
The gauge Fig. 1 only works when the ignition is switched on. The LED at the bottom of the dial flashes for a few seconds after the ignition is switched on. When the gauge reaches the reserve zone, the LED at the bottom of the dial will light up in red. The LED at the bottom of the dial will flash if the gas level is very low.
When the gas fuel level is down to the reserve zone, the message Please add CNG will appear in the instrument cluster.
When both types of fuel (natural gas and petrol) are down to the reserve zone, a combined display Fig. 2 will appear in the instrument cluster with the message Please refuel and the indicator lamp

Caution!
Never run the petrol tank completely dry. If there is an irregular fuel supply, misfiring can occur. Unburnt fuel can then enter the exhaust system. This can lead to overheating and damage to the catalytic converter.
Note
If the vehicle is refuelled and parked immediately afterwards for a long period, the fuel level shown on the gas fuel gauge may be different when you restart the vehicle than it was immediately after refuelling. This does not mean that there is a fuel leak, but is a side-effect caused by a drop in pressure in the gas fuel tanks when the system cools down after refuelling.
