When the ECO light appears in a car, it indicates that the vehicle's economical driving mode has been activated. The ECO mode primarily functions by comprehensively analyzing and judging various factors that affect fuel consumption during vehicle operation, including automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit then calculates the optimal fuel quantity to be supplied to the engine for operation, effectively reducing fuel consumption compared to normal driving mode. The three key qualities that the ECO intelligent engine family series products consistently pursue are technology, environmental protection, and economy. When the vehicle speed exceeds 120 km/h, priority is given to speed, and the ECO mode automatically deactivates.

Why does the car still pull to one side when the four-wheel alignment data is correct?

The four-wheel alignment data is correct but the car still pulls to one side because the tire tread patterns on both sides are different or the tread depth is uneven. Below is relevant information about tires: 1. Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. 2. Tire Aging: Tires are rubber products and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage is low. Tires can also age if left unused for long periods, so it's important to check the production date when purchasing new tires.
