Today we will explain how to reset the service light related to the car service. The service light comes on when it is necessary to proceed with the regular maintenance of the vehicle.

The service includes replacing the fluids inside the vehicle or topping them up, as well as replacing filters and checking the timing belt and engine. After that, it is necessary to proceed with resetting the light which will update the kilometers until the next service.

To perform this operation on a 2010 Mercedes S-Class vehicle, we need to turn on the instrument panel and immediately press the "Trip A" button to access the kilometers. Then, we press the answer call and ok buttons simultaneously to access the service menu.

From the service menu, we select the options "assist plus", "full service", and "reset"; after completing all the steps, we return to the main menu and restart the vehicle to complete the reset.

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.
