Exo will not appear on modern on-board instruments, it should be eco, which means economic mode. Active eco driving mode generally has buttons, and the owner can choose whether to turn it on or not. The main principle of eco mode is to comprehensively judge and analyze the automatic transmission gear, vehicle speed, braking, transmission oil temperature and other conditions that affect fuel consumption during vehicle driving. The eco control unit calculates the optimal fuel quantity and provides it to the engine to do work, so that the fuel consumption is effectively reduced compared with the ordinary driving mode. Simply put, it is to control the engine speed with a reasonable gear to reduce unnecessary fuel consumption.

Eco mode does not work in the following cases:

First, when the vehicle speed exceeds 120km/h, the vehicle speed takes priority at this time, and the energy-saving mode automatically fails. In other words, if the economic speed is greatly exceeded (usually between 60 and 90 km/h), the eco mode will not save fuel.

Secondly, the eco mode is mainly controlled by the computer when the vehicle is running, so the eco function does not work when the vehicle is idling or in N, P and manual modes.

Thirdly, when it is necessary to overcome a certain resistance and need a large torque output, such as climbing a hill, the ECU computer judges that the priority is to ensure enough power to drive the vehicle, and the eco mode does not work.

In fact, eco mode is more like an intelligent fuel-saving escort, guiding car owners and reminding them to drive in the right way. When the best fuel supply is reached, the dashboard will display the green word "eco" synchronously. The word' eco' will disappear if you press the accelerator pedal hard to accelerate, or if you encounter a climbing section. When the eco mode is turned on, firstly, the vehicle will automatically match the best gear and speed to reduce fuel consumption. At the same time, the owner needs to actively control the throttle and brake during driving to achieve the best fuel consumption. Million car purchase subsidy
