If a warning light appears on your car's dashboard indicating that the AdBlue level is too low, it's time to refill the tank. Before proceeding, obtain a canister of this anti-pollution liquid for Diesel engines and ensure you perform the entire operation with the engine off. Go to the side where the tank flap is located, open it, and unscrew the blue cap. Using a common funnel or a rubber hose, pour the new liquid into the AdBlue tank.

Fill it completely and finally screw the cap back on.
