Mercedes-Benz C-Class (W205) 2015 - 2021 Owners Manual: Refueling

Refueling the vehicle

WARNING Risk of fire or explosion from fuel
Fuels are highly flammable.
  • Fire, open flames, smoking and creation of sparks must be avoided.
  • Switch off the ignition and, if available, the stationary heater, before and while refueling the vehicle.

 

WARNING Risk of injury from fuels
Fuels are poisonous and hazardous to your health.
  • Do not swallow fuel or let it come into contact with skin, eyes or clothing.
  • Do not inhale fuel vapor.
  • Keep children away from fuel.
  • Keep doors and windows closed during the refueling process.

If you or other people come into contact with fuel, observe the following:

  • Immediately rinse fuel off your skin with soap and water.
  • If fuel comes into contact with your eyes, immediately rinse them thoroughly with clean water. Seek medical attention immediately.
  • If you swallow fuel, seek medical attention immediately. Do not induce vomiting.
  • Change immediately out of clothing that has come into contact with fuel.

 

WARNING Risk of fire or explosion from electrostatic charge
Electrostatic charge can create sparks and thereby ignite fuel vapors.
  • Before you open the fuel filler cap or take hold of the pump nozzle, touch the metallic vehicle body.

    This discharges any electrostatic charge that may have built up.

  • Do not get into the vehicle again during the refueling process.

    Otherwise, electrostatic charge could build up again.

 

NOTE Damage caused by the wrong fuel
Vehicles with a gasoline engine: Even small amounts of the wrong fuel could result in damage to the fuel system, the engine and the emission control system.
  • The RON requirement is located in the fuel filler flap.
  • Only refuel with low-sulfur unleaded fuel.

This fuel may contain up to 10% ethanol. Your vehicle is suitable for use with E10 fuel.

Never refuel using any of the following fuels:

  • Diesel
  • Gasoline with more than 10% ethanol by volume, e.g. E15, E85, E100
  • Gasoline with more than 3% methanol by volume, e.g. M15, M30, M85, M100
  • Gasoline with additives containing metal

If you accidentally refuel with the wrong fuel:

  • Do not switch the ignition on.
  • Consult a qualified specialist workshop.

 

NOTE Do not use diesel to refuel vehicles with a gasoline engine.
If you accidentally refuel with the wrong fuel:
  • Do not switch the ignition on. Otherwise fuel can enter the engine.

    Even small amounts of the wrong fuel could result in damage to the fuel system and the engine. The repair costs are high.

  • Consult a qualified specialist workshop.
  • Have the fuel tank and fuel lines drained completely.

 

NOTE Fuel may spray out when you remove the fuel pump nozzle.
  • Only fill the fuel tank until the pump nozzle switches off.

Requirements:

  • The vehicle is unlocked.

Do not get into the vehicle again during the refueling process. Otherwise, electrostatic charge could build up again.

Observe the notes on operating fluids.
