Several warning and indicator lamps will light up briefly as a functional check when the ignition is switched on. They will switch off after a few seconds.
Autogas engines
The yellow indicator lamp
lights up when all the fuel except
for the reserve fuel has been used up.
The green indicator lamp 
lights up when the vehicle is in autogas mode.
The green indicator lamp
goes out if the vehicle is changed over to petrol mode automatically or manually.
Things to note: if the vehicle is parked for an extended period directly after refuelling, it is possible that the needle on the autogas gauge will not display exactly the same fuel level shown directly after refuelling when the vehicle is restarted. This does not necessarily indicate a leak in the system.
WARNING
- When the fuel level is too low, the fuel supply to the engine could be irregular, especially when driving up or down hills and inclines.
- The steering, all driver assist systems and brake support systems will not function if the engine sputters or stops completely due to a lack of fuel or irregular fuel supply.
- Always fill the tank when it is still 1/4 full. This reduces the risk of running out of fuel and breaking down.
NOTICE
- To avoid damage to your vehicle, always observe the indicator lamps and associated warning texts.
- Do not run the tank empty. Irregular filling periods can cause backfiring and allow unburnt fuel to enter the exhaust system. This could cause damage to the catalytic converter!
The small arrow next to the petrol pump symbol in the display instrument shows you the side of the vehicle on which the tank flap is located.
