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 ; this could cause your vehicle to malfunction.
Fuel fl ap
To open, press at the top left-hand corner, then pull open from the left.
Locking fi ller cap
Turn the key a quarter turn to lock and unlock the fi ller cap.
When refuelling, place the cap on hook A.
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.
Tank capacity
The tank has a capacity of approxi-mately 71 litres.
