Markings above the switch show the current fuel level.
| Number of LEDs | Colour of LEDs | Fuel level (%) | 
|---|---|---|
| 5 | Green | 100 | 
| 4 | Green | 80 | 
| 3 | Green | 60 | 
| 2 | Green | 40 | 
| 1 | Green | 20 | 
| 1 | Orange | 10 | 
When the vehicle gas tank is empty the switch sounds 3 times. The level gauge extinguishes and the system automatically changes over to petrol.
Note
 Ensure that the petrol tank never runs dry because the car always starts on petrol.
