autohold is an automatic parking system. The reason it may not light up could be that the car is not in the started state, the door is not properly closed, the ESP is not functioning correctly, or the seatbelt is not fastened. Here is some additional information: 1. Implementation conditions: AUTOHOLD relies on an intelligent braking system, and only vehicles equipped with brake control systems like ESP can implement the AUTOHOLD function. 2. Principle: The AUTOHOLD automatic parking function provides accurate parking force through a slope sensor controlled by the controller. When starting, the parking control unit calculates information provided by the clutch distance sensor, clutch engagement speed sensor, throttle pedal sensor, etc. It automatically releases the parking brake when the driving force exceeds the driving resistance, allowing the car to start smoothly.

How to Remove the ETC Tag?

You can use a hairdryer to blow hot air at the junction between the OBU device and the windshield. The adhesive tape on the back of the device will soften when heated, reducing its stickiness. Then, the owner can slowly twist and remove the OBU device by hand or use a plastic scraper to gently pry it off. Another method is to soak a towel in hot water and place it on the outer side of the windshield. This will also heat the adhesive tape on the back of the OBU device. Wait for the tape to soften before removing the device. Alternatively, you can use sunlight to heat the adhesive tape on the back of the OBU device. On a hot, sunny day, park the car in an open area to expose the device to intense sunlight until it softens, then remove it. You can also visit the service center where you applied for the ETC and ask the staff for assistance. They may spray some tar remover and then use a plastic scraper to slowly pry off the OBU device. Benefits of Installing ETC: Saves time by eliminating the need to wait in queues. Environmentally friendly, as vehicles can pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution. Reduces wear and saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption. Users can also enjoy a 5% discount on toll fees. Improves efficiency, as ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

Do You Need to Replace Two Tires at the Same Time?

Not all vehicles require replacing two tires at the same time when changing tires. However, for safety reasons, it is recommended to replace both tires together. Below are the relevant details regarding tire replacement: 1. Tire Wear: If the vehicle is new and has not been driven extensively, only the problematic tire needs to be replaced, as the wear on tires on the same axle will be similar. 2. Mileage: If the tires have been driven tens of thousands of kilometers but do not yet need replacement, and only one tire has an issue, replacing just one tire may cause uneven height, leading to bumpy rides or steering issues at higher speeds. In such cases, it is best to replace a pair of tires.

Where is the spare tire of a car placed?

Car spare tires are generally placed under the trunk mat, some cars have the spare tire mounted on the rear, and some have it under the chassis. A car spare tire is a backup tire prepared to replace the main tire in case of any issues. Placing the spare tire under the trunk mat is widely used in current sedan models, as it not only saves space but also does not affect the overall aesthetics of the car. Rear-mounted: It is also common to place the spare tire on the rear, especially for some rugged off-road SUVs, which can further highlight their boldness. A spare tire mounted on the rear does not occupy any space at all and is also relatively convenient to access.

Is Dynamic Balancing Necessary for Rear Tires?

If the rear tires have been replaced or repaired, the mass of the rear wheels will be altered, requiring dynamic balancing. However, if the rear tires have neither been replaced nor patched, meaning their mass remains unchanged, dynamic balancing is unnecessary. Generally, only the tire whose mass has been altered in any part needs balancing. Automobile tires are one of the crucial components of a vehicle, directly contacting the road surface and working together with the suspension system to absorb shocks during driving. Tires can be classified by structure into radial tires and bias-ply tires, and by tread pattern into ribbed tires, transverse pattern tires, mixed pattern tires, and off-road pattern tires.
