Refuelling. Important safety information. Refuelling procedure

The “Refuelling” section of the Mercedes E-Class (4th gen, W212, 2009–2016) contains important safety information and describes the refuelling procedure step by step. Information on the correct fuel grades and protection against misfuelling ensures safe and smooth refuelling.

Important Safety Notes

WARNING

Fuels are highly flammable. Improper handling of fuel creates a risk of fire and explosion!

Avoid open flames, naked lights, smoking and sparks at all times. Before refuelling, switch off the engine and, if fitted, the auxiliary heater.

WARNING

Fuels are toxic and harmful to health. There is a risk of injury!

Avoid fuel contact with skin, eyes or clothing, and do not swallow fuel. Do not breathe in fuel vapours. Keep fuels away from children.

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

• If fuel gets on your skin, wash it off immediately with soap and water.
• If fuel gets into your eyes, rinse them immediately and thoroughly with clean water. Seek medical attention without delay.
• If fuel has been swallowed, seek medical attention immediately. Do not induce vomiting.
• Change clothing that has become wet with fuel immediately.

WARNING

Electrostatic charging can cause sparks and ignite fuel vapours. There is a risk of fire and explosion!

Always touch the vehicle body immediately before opening the fuel filler cap or handling the fuel nozzle. This discharges any static electricity that may be present.

WARNING

Vehicles with diesel engine:

If you mix diesel fuel with petrol, the flash point of the fuel mixture is lower than that of pure diesel fuel. With the engine running, exhaust system components can overheat unnoticed. There is a risk of fire!

Never refuel with petrol. Never mix petrol into diesel fuel.

NOTE

Do not fill vehicles with gasoline engines with diesel. If you have accidentally fueled with the wrong fuel, do not switch on the ignition. Otherwise the fuel may enter the fuel system. Even small amounts of the wrong fuel can cause damage to the fuel system and engine. Contact a qualified workshop and have the fuel tank and fuel lines completely drained.

Do not fill vehicles with diesel engines with gasoline. If you have accidentally fueled with the wrong fuel, do not switch on the ignition. Otherwise the fuel may enter the fuel system. Even small amounts of the wrong fuel can cause damage to the fuel system and engine. Repair costs are high. Contact a qualified workshop and have the fuel tank and fuel lines completely drained.

If you overfill the fuel tank, you may damage the fuel system.

Make sure that you do not spill fuel on painted surfaces. Otherwise you may damage the paint.

When refueling from a canister, use a filter. Otherwise particles from the canister may clog the fuel lines and/or the injection system.

Do not get back into the vehicle while refueling. You could build up an electrostatic charge again.

If you overfill the fuel tank, fuel may spray out when you remove the fuel nozzle.

Refueling

General Information

Observe the important safety information.

When you lock or unlock the vehicle with the key or KEYLESS-GO, the fuel filler flap is also locked or unlocked automatically.

The fuel filler flap position is shown in the instrument cluster. The arrow on the fuel pump indicates the side of the vehicle.

Open the fuel filler flap

Open the fuel filler flap (sedan example)

	Open the fuel filler flap
	Insert the fuel filler cap
	Tire pressure table
	Information label for the fuel grade to be filled

Switch off the engine.

Remove the key from the ignition lock.

or, on vehicles with KEYLESS-GO

Open the driver's door.

The ignition lock is now in position 0. This means "key removed". The driver's door can be closed again.In the direction of the arrowPress on the fuel filler flap.

The fuel filler flap opens slightly.

Turn the fuel filler cap to the left and remove it.

Sedan: Insert the fuel filler cap into the holder on the inside of the fuel filler flap..

or

Estate: Insert the fuel filler cap horizontally from above into the recesses in the hinge arm of the fuel filler flap.

Push the nozzle of the fuel dispenser fully into the filler neck, hook it in place and refuel.

Fill the fuel tank only until the fuel nozzle shuts off.

Do not add any more fuel after the fuel nozzle has shut off automatically the first time. Otherwise fuel may overflow.

Vehicles with diesel engines: The filler neck is designed for refueling at diesel dispensers.

Close the fuel filler flap

Place the fuel filler cap on the filler neck and turn it to the right until it clicks into place.

Press the fuel filler flap closed until it clicks into place.

Close the fuel filler flap before locking the vehicle. Otherwise a locking pin of the central locking system will prevent the fuel filler flap from closing.

The Mercedes E-Class W212 (model years 2009–2016) uses the highest safety standards when refueling. Numerous notes and warnings protect against hazards such as fire or damage to the fuel system.

The well-designed refueling process and precise instructions help ensure that every refueling stop is safe and trouble-free, another example of Mercedes-Benz's high quality standards.

Question: Why should you not continue refueling after the fuel nozzle has shut off the first time?

Answer: To prevent overflow and damage to the fuel system.

Question: What should you do if you have fueled with the wrong fuel?

Answer: Do not switch on the ignition and contact a workshop immediately to avoid damage.
