What does the AdBlue warning light in the Citroen C5 Aircross indicate?

Model: Citroen C5 Aircross MK 1 - Years 2017-2022
Part: AdBlue warning light

The AdBlue warning light on a diesel vehicle indicates that it is necessary to top up the liquid inside the tank. To perform this simple operation on a Citroen C5 Aircross car, we must open the diesel tank door, next to the diesel refueling cap there is the blue AdBlue cap. We pour about 17 liters of additive into the tank. The additive can be purchased online or at auto parts stores, and in some gas stations it is possible that there is a pump for the system. After refueling, we must get into the car and press the "000/CHECK" button. By holding down the button, the warning light reset will start automatically and once completed we can hit the road.
