If you see the AdBlue pollution control system pop-up on the dashboard of your Citroen C4 Picasso, you need to refill the fluid. Open the boot, lift the right side panel, and locate the tank cap (positioned at the top left of the folding seat).

Open the tank and pour the required amount of fluid using a funnel; use a cloth or something similar to protect the carpet from any spills. Once you have poured the appropriate amount, securely close the cap and check that the AdBlue message is no longer displayed on the gauge.
