As you know, the starter belt on the Smart 451 is subject to severe wear. It is recommended to replace it after 37,000 miles, but it rarely lasts that long.

In reality, it breaks between 12,000 and 25,000 miles, and if it happens on the motorway, it can overheat the engine causing severe damage. Therefore, not using Start & Stop can be a way to prolong its life.

Here's how to do it: press the "off" button on the central console, and insert a paperclip against the button to simulate continuous pressure. This way, the Start & Stop system will always be disabled, simply and economically.

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.
