If you should put in fuel that is not suitable for your vehicle's engine type, it is imperative to have the tank drained be fore you start the engine again.
While you are refuelling, the engine must be stopped and the ignition switched off.
For a petrol engine with a cata-lytic converter, unleaded fuel is compulsory.
The fi ller neck is narrower to ensure that only unleaded petrol can be put in.
When you are seeking to fi ll your tank, do not persist after the third cut-off; that could cause your vehicle to malfunction.
Fuel must be added in quantities of more than 5 litres to be recog-nised by the fuel gauge.
To open the fl ap, press button A. Undo the cap and attach it to the tab on the inside of the fl ap.
Opening the cap can trigger a vac-uum. This results in a noise caused by the sealing of the fuel circuit.Note: The fuel fl ap is locked when you lock your vehicle with the remote control.
FUEL QUALITY
A label inside the fi ller fl ap tells you which type of fuel to use.
The petrol engines are designed to run on RON 95.
However, for better performance (petrol engine), we recommend RON 98
