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

First, purchase a 10-litre canister of urea from any car parts store, then switch off the engine and open the boot.

Lift the floor panel of the boot, remove the circular cap, and pour the necessary amount of fluid into the hole to reach the maximum level.
