With the vehicle unlocked, to open flap b, slide your finger into cutout c.

Flap a is integrated into the filler pipe.

For refuelling, refer to the "Refuelling" section.

To close, push the flap by hand until it stops.

Fuel quality

Use good-quality fuel that complies with the current standards applicable in each country and that strictly matches the information on the label located on flap B. Refer to the "Engine specifications" section in chapter 6.

Diesel versions

Only use diesel that complies with the information on the label located inside flap B.

Petrol versions

Only use unleaded petrol. The octane rating (RON) must match the information on the label located on flap B. Refer to the "Engine specifications" in chapter 6.

appuyer avec les doigts sur le clapet A.Never press flap A with your fingers. Do not wash the filler area with a high-pressure cleaner.

Vehicles running on ethanol-based fuel

Only use unleaded petrol or a fuel containing a maximum of 85% ethanol (E85).

In extreme cold, starting the engine may be difficult, or even impossible.

To avoid this problem, use unleaded petrol or, for vehicles so equipped, use the engine block heater: connect the specific end of the supplied extension cable to the socket built into the radiator grille and the other end to a 220 V socket for at least 6 hours before starting.

Note: when using this fuel you may notice higher fuel consumption.

mélanger d'essenceDo not mix petrol (unleaded or E85) with diesel, even in small quantities.

Do not use ethanol-based fuel if your vehicle is not designed for it.

Refuelling

Insert the nozzle to push back flap A and push it fully in before triggering it to fill the tank (risk of splashing). Keep it in this position throughout the filling operation.

After the first automatic shut-off at the end of filling, you may trigger the nozzle up to two more times at most, to leave room for fuel expansion.

During refuelling, make sure no water enters. Flap A and its surround must remain clean.

Petrol versions

Using leaded petrol would damage the emission control systems and could void the warranty.

To prevent filling with leaded petrol, the fuel filler neck has a restrictor with a safety system that only allows the use of an unleaded petrol nozzle (at the pump).
