Refuelling procedure
When handling fuel, observe the safety regulations applicable at filling stations.◄

► reduced fuel vapor recovery.
The tank can be considered full when the fuel nozzle shuts off for the first time.
Fuel Tank Capacity
Approximately 60 liters, including reserve:
► gasoline engines – approximately 8 liters;
► diesel engines – approximately 6.5 liters.
When the driving range is less than 50 kilometers, be sure to refuel, otherwise you risk damaging the engine.◄
