The hydrophilic function of the exterior rearview mirror means that rainwater forms a thin film on the mirror, which, combined with the mirror's heating function, easily evaporates the moisture, keeping the lens dry and clear. How to use the rearview mirror heating: When the exterior rearview mirror surface is frosted or fogged, press the rear defrost button. The indicator light will illuminate, and the exterior rearview mirror defrost function will activate. Press the rear defrost button again to turn off the defrost function. Precautions for rearview mirror heating: The exterior rearview mirror defrost function automatically turns off after operating for a period of time. After activating the exterior rearview mirror defrost function, do not touch the mirror surface to prevent burns. (Haval F7 air conditioning control panel: the yellow circle indicates the front defrost button, and the red circle indicates the rear defrost button.) Do not use the defrost function for an extended period when the vehicle is not started to avoid draining the battery.

How many kilometers are considered as a nearly new car?

50 kilometers or less is considered a nearly new car. Currently, there are no mandatory national requirements for the mileage of new cars. However, under normal circumstances, if the vehicle is domestically produced, its mileage is mostly within 50 kilometers. For imported vehicles, considering factors such as transportation, port handling, and customs, the mileage is mostly within 100 kilometers, but this is not a standard. Mileage is not the sole criterion for determining a car's condition. When purchasing a car, you should also pay attention to the following issues: 1. Check the vehicle identification number and the production date and manufacturer on the vehicle's nameplate; 2. Open the engine hood and inspect whether the components inside the engine compartment are clean, tidy, and show any signs of manual modification; 3. Check the vehicle's undercarriage components for oil leaks, fluid levels, and any signs of impact.

How to enable auto-locking for Honda Fit?

Fit does not have an auto-locking function, only manual locking. If you want to use this feature, you can install a device plugged into the OBD interface.

The Fit is a hatchback launched by GAC Honda. The body dimensions are 4065mm in length, 1695mm in width, and 1525mm in height. 2.
