If the message "immobiliser active" appears when starting the engine and you cannot start the car, first perform a diagnostic check of the system to see if there are any stored errors in the control unit. If there are none, test the fuses with a tester.

Finally, if all the fuses are fine, check the immobiliser key located just below the ignition key housing. To access it, remove the covering panel from the steering column.

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.
