The SET button on a car is for setting the cruise control function. Generally, the SET button needs to be combined with RES (Reset), CRUISE (Cruise), and CANCEL (Cancel) to achieve the cruise control function. Cruise control is divided into fixed-speed cruise and full-speed adaptive cruise. The role of SET: It automatically maintains the vehicle speed as required by the driver without the need to press the accelerator pedal, allowing the car to drive at a fixed speed. When the fixed-speed cruise function is activated, pressing the accelerator can increase the speed to be equal to or higher than the lower speed limit of the cruise control. Once the fixed-speed cruise function is confirmed, the engine fuel supply will automatically adjust to meet the power demand for the current speed. How to use fixed-speed cruise in a car: Locate and press the fixed-speed cruise button on the steering wheel. When the car reaches the desired cruise speed, press the SET button downward. After setting the cruise speed, you can press the button upward or downward to fine-tune the cruise speed. It is important to always pay attention to the road conditions while using fixed-speed cruise.

What is a Car Differential?

A car differential is a device composed of left and right half-shaft gears, two planetary gears, and a gear carrier. The following is an introduction to the functions of a car differential: 1. Differential Principle: The differential is designed to adjust the speed difference between the left and right wheels. In four-wheel drive systems, to power all four wheels, they must be connected. If all four wheels are mechanically linked, the car cannot rotate at the same speed when turning. To ensure that the car maintains a relatively consistent rotational speed during turns, a center differential is added to adjust the speed difference between the front and rear wheels. Four-wheel drive vehicles encounter many issues during operation, such as sharp turn braking and interference between front and rear drive wheel systems. Since the differential can absorb the speed difference of the front wheels, adding a center differential allows the front and rear drive shafts to rotate at different speeds. 2. Differential Function: The car differential primarily eliminates mechanical interference caused by inconsistent rotational speeds of the left and right wheels during turns. Without a differential, mechanical damage would occur due to the speed mismatch between the left and right wheels. For example, ordinary human-powered tricycles do not have a differential installed, so they can only use single-side drive when turning.

How to Use a USB Drive to Listen to Music in the Car?

If the car does not have a USB device, it cannot play songs from a USB drive. First, locate the USB port, then insert the USB drive containing music into the USB port. On the central control unit, you need to switch the input medium to USB. Here are the detailed steps: 1. Locate the USB port: First, find the position of the USB interface. Some models have easily accessible USB ports, usually located in the glove box or under the center console. You can refer to the manual to confirm the USB port's location. 2. Insert the USB drive: After formatting the USB drive, create a new folder to save the music, then insert it into the USB port. 3. Adjust the central control: Next, locate the car's central control panel, turn on the power switch, and follow the on-screen instructions. Different central control units operate differently, so you need to find the input menu and switch it to USB. Generally, the central control unit will automatically recognize the songs and start playing them. 4. USB drive format: The USB drive must be in FAT32 format. If it is not in this format, format it accordingly. The USB drive should have a single partition, meaning it cannot be a bootable drive with hidden partitions.

Does the engine shake when the steering wheel is turned to the limit?

When the steering wheel is turned to the limit, there may be shaking and vibration, sometimes accompanied by noise, mostly caused by steering gear pressure relief or air resistance in the power steering fluid (mechanical). The following is additional information: Steering wheel shaking at idle: The situation where the steering wheel shakes at idle. The amplitude of this shaking is not very large and is mostly caused by resonance. This vibration has little impact on the use of the car. It is necessary to check whether there are any issues with the rubber sleeve of the steering wheel transmission device and whether the bolts fixing the steering wheel transmission device are loose. Additionally, check whether the steering wheel shaking is related to the idle speed of the engine and the steering gear. Steering wheel shaking while driving: During driving, the steering wheel may shake and vibrate. A very significant cause of this situation comes from the tires. Tires must be balanced when rolling, and a specialized dynamic balancing machine should be used to check them. Then, counterweights should be added to unbalanced tires to improve balance. Once the wheel dynamic balance is inaccurate, it will cause radial jumping of the wheels during driving. This jumping is transmitted to the steering wheel through the steering transmission mechanism, which will cause the steering wheel to shake.
