What is the function of the small square on the dashboard of the Baojun RS3?

[Genesis]

The function of the small square on the dashboard of the Baojun RS3 is to alert the owner of an engine malfunction, indicating that the vehicle's engine requires maintenance or servicing. The specific reasons are as follows: Carbon buildup inside the engine cylinders: After a certain period of use, the engine will inevitably accumulate carbon deposits. These deposits can alter the engine's design parameters and are inherently unstable, trapping heat. This trapped heat can cause uncontrolled ignition, leading to engine knocking. In such cases, the engine fault light will illuminate. Poor combustion state: A poor combustion state is the primary reason for the engine fault light to come on. In automotive design, to ensure the engine operates in good condition and maintains a normal working lifespan, an oxygen sensor is installed to monitor the combustion state. If the combustion state is poor, it not only pollutes the environment but also leads to fuel wastage and excessive engine wear.
