What does the 'Low to Reserve Fuel Level' warning mean in Mercedes-Benz vehicles?

[OAlyssa]

Mercedes-Benz 'Low to Reserve Fuel Level' indicates that approximately 10-15% of the fuel tank capacity remains. Introduction to Low to Reserve Fuel: The 'Low to Reserve Fuel Level' warning appears when the fuel supply has dropped to the reserve level. This is consistent across most Mercedes-Benz models, with the reserve fuel typically allowing for about 100 kilometers of driving. However, considering factors such as driving habits, road conditions, and vehicle condition, the actual range may be around 80 kilometers. Of course, the exact distance depends on the vehicle's usual fuel consumption. Refueling Precautions: If the fuel level in the tank is frequently too low, the fuel pump may not be adequately submerged in gasoline, affecting its cooling and potentially shortening its lifespan. In cases of extremely low fuel or complete depletion, the fuel pump may even burn out. Once the fuel pump is damaged, it usually requires replacement of the entire fuel pump assembly.
