Video tutorial

Let's see how to reset the service light "A" of a Mercedes GLK. We need to close all the doors and turn on the ignition, then using the turn signals (or the "comand" knob) we display the "trip" screen with the kilometers traveled. Make sure we are on the screen with the total odometer, and at this point, we simultaneously press and hold the "ok" button and the "call/phone" button.

After a few seconds, the service menu will appear. Use the arrow keys to navigate to "assyst plus" and here select "full service" and confirm with "yes." Now turn off the ignition, wait 30 seconds, and turn it back on: the service light A should be off.

How to Reset the Tire Pressure Light on a MG ZS?

On the instrument cluster of the MG ZS, the tire pressure light that appears can be reset by inflating the tires to the correct pressure: this value will be indicated on the sticker attached to the driver's door pillar. Once the tires have been properly inflated, you can turn on the instrument cluster and navigate through the menu until you find the option that indicates tire pressure: if this screen shows the new values, the light will turn off; otherwise, you will need to drive for a few miles so that the sensors can read the new values and turn off the light afterward.
