cruise-main light being on indicates that the vehicle's electronic cruise control system has been activated. Below is some information about the electronic cruise control system (cruise-main): 1. The vehicle's electronic cruise control system - when the cruise control system's indicator light is on, it serves as a reminder that the cruise control mode has been activated. However, the cruise control system can only be engaged when the vehicle speed exceeds 40km/h. 2. When driving on highways, after setting the desired speed, you can release the accelerator pedal, and the vehicle will maintain the preset speed automatically.

The Cruise Main light being on typically indicates that your cruise control system's main switch is activated. This means the cruise function is in standby mode, ready for you to set the speed. Simply put, it doesn't automatically start cruising; you need to press the set button on the steering wheel to activate it, such as setting a constant speed for highway driving. Cruise control systems adjust the throttle electronically to make driving more effortless and fuel-efficient, which is particularly useful for long-distance or highway driving. However, don't forget to check if it's functioning properly—if the light flashes or stays on for no reason, there might be a short circuit or a stuck button that needs fixing. In short, don't worry when the light is on; just make sure you understand how to operate it to avoid accidental activation, especially for beginners under stress. For maintenance, it's recommended to periodically check the manual or simply clean the buttons to prevent dust-related malfunctions.

What are the reasons for the heavier steering wheel of the Fit?

The reasons for the heavier steering wheel of the Fit are: 1. Dirty power steering fluid: The power steering fluid is the force transmission medium. If the fluid is too dirty, it will cause poor circulation, making steering difficult; 2. Lack of power steering fluid or oil leakage: A lack of power steering fluid is equivalent to having no power assistance. Check the relevant system for any signs of oil leakage; 3. The engine power steering belt is too loose or too tight, or the belt is aged. The tightness can be adjusted, but an aged belt can only be replaced. Taking the Fit 2021 1.5L CVT Trend Edition as an example: It is a compact car launched by GAC Honda, with a length, width, and height of 4109mm, 1694mm, and 1537mm respectively, and a wheelbase of 2530mm.
