If the AdBlue warning light is on in the instrument cluster of your GMC Yukon, it means that the fluid in the emissions system has reached the minimum level and needs to be refilled. This is a very simple and quick operation; let's see how to proceed in this tutorial.

First, purchase a jug of urea at an auto parts store, then turn off the engine and open the fuel door. Next, unscrew the blue cap, insert the hose into the jug, and add the necessary amount of fluid to reach the maximum level.
