If the AdBlue warning light has illuminated on the dashboard of your Citroen C4 Grand Picasso, it means that the emissions fluid has dropped to a too low level and needs to be topped up. To do this, you will need a 10-litre can of fluid, which can be purchased from any car parts store.

Before refilling, ensure that the engine is turned off, then open the rear hatch, remove the floor panel, and unscrew the cap located on the right side.

Finally, insert the nozzle into the opening and add the necessary amount of fluid to reach the maximum level.
