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.
To open the fl ap, press button A. Undo the cap and attach it to the tab on the inside of the fl ap.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 perform-ance (petrol engine), we recom-mend RON 98
