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 | Red | 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.
