How to Top Up AdBlue on a Citroën C4 Cactus?

Model: Citroen Cactus MK 1 - Years 2014-2020
Part: AdBlue warning light

To top up AdBlue on the Citroën C4 Cactus, open the rear hatch of the car to access the components inside the boot: here you can lift the carpet that serves as flooring, revealing the spare wheel underneath. This wheel must be removed from its place, as underneath it is the cap for the AdBlue tank: by unscrewing this cap, you will gain access to the tank where the liquid needs to be poured. After topping up, close the cap and check that the corresponding warning light has turned off.
