When the AdBlue warning light comes on in a Land Rover Discovery, it means you need to refill the fluid in the tank because you have only a few miles left before the emissions system locks the vehicle. To refill, open the hood and then unscrew the cap of the tank located near the engine.

After removing the cap, you can pour in the fluid. Once finished, replace the cap and close the hood.

To reset the warning light, simply rev the engine or drive a short distance.
