In this video, let's see how to change the consumption display from litres/100 km to litres/km on a Mercedes GLA W156. This operation must be done through the infotainment screen, so now go to "vehicle". From here, select the "consumption" option, where the consumption is indicated by default in litres per 100 km. If you want to change it, you need to enter the "engineering" menu.

Then go to the buttons located below the screen, press the red handset and simultaneously press the "1" button and the "#" button; after a few seconds, the screen changes appearance and takes you into the engineering menu.

Go to "system"/"logging"/"enable log mark"/"variant coding"/"page 1". Here, scroll down to page 2 and look for the entry "fuel consumption": you will see it is set to l/100km. Go to the right arrow and set it to km/l. Scroll down to "set page", confirm, restart the system by holding down the power button for a few moments, and now you will find km/l in the consumption display.
