The tires lack pressure sensors. The system identifies variations in the rotation of each wheel via the ABS, but it does not specify which wheel is affected, resulting in the display showing all wheels collectively.
If a tire is deflating, that wheel must complete more revolutions than the others to cover the same distance due to its reduced circumference in comparison to the others.
Ensure that all tyres are properly inflated, which may differ between front and rear if hauling loads in the boot, and thereafter reset the monitoring system.
I cannot specify the exact location of the reset, however it will be found under Driving or a similar category.
Subsequent to that action, the system will only alert you if any tyre pressure falls below the predetermined levels, allowing you to identify the specific tyre, or maybe multiple tyres if unfortunate, and examine the underlying problem.
