If the AdBlue warning light has come on in the instrument panel of our Citroen C4 Cactus, it means that the fluid in the pollution control system has reached the minimum level and, consequently, needs to be topped up. This is an extremely simple and quick operation; let's see how to proceed in this tutorial.

First, we need to purchase a 10-liter canister of urea from an auto parts store.

Then, we make sure that the engine is off and open the fuel door. Next, we unscrew the blue cap, insert the hose from the canister into the opening, and add the necessary amount of fluid to reach the maximum level.

Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
