To ensure the AdBlue warning light on the Peugeot 308 completely disappears from the instrument cluster, you need to top up by adding the necessary amount of additive fluid: to do this, open the fuel flap located at the rear right of the vehicle. You can now open the blue cap to insert the required amount of additive fluid to fill the tank: once the top-up is complete, close the cap and the flap, ensuring that the warning light has disappeared from the vehicle's instrument cluster.
