  • during refuelling, place the cap at position A,
  • fill the tank, but do not force the nozzle beyond the third automatic cut-off; this could cause malfunctions of your vehicle.

Refuelling must be done with the engine off and the ignition switched off.

For petrol engines with a catalytic converter, unleaded fuel is mandatory. Fuel top-ups must be more than 5 litres to be registered by the fuel gauge. The filler neck has a narrower orifice that only accepts unleaded petrol. Opening the cap may cause a suction noise. This vacuum, which is completely normal, is caused by the sealing of the fuel system. ! With Stop & Start, never refuel when the engine is in STOP mode; always switch off the ignition with the key.
