What is the reason for the reverse radar not displaying images?

When the car is just started, it may interfere with the operation of the reverse camera. You can try restarting to see the situation. The following are related introductions about reversing: 1. Precautions: Whether you are a novice or an experienced driver, this is a must-notice point. Not only should you not step on the accelerator while reversing, but you should also not half-step on the brake, especially for novices who should drive at a speed slower than idle speed. This way, you will have more time to observe the surrounding environment. 2. Basic essentials: When parking in a parking lot, first, visually estimate the width of the parking space, whether there are obstacles behind, whether there are cars parked on both sides, and whether the length is suitable for your car model. If you can't see clearly at night, get out and observe the exact position before reversing.

Can You Continue Driving with a Damaged Tire Tread?

Tire tread damage requires assessment based on the extent of the damage to determine if continued use is possible: If only the outer layer is slightly scratched with surface damage that doesn't affect the tire's structural integrity, it can still be used; however, if the sidewall is scraped with a large area or deep damage, it must not be used further. Continued use in such cases may lead to bulging at the damaged area, significantly increasing the risk of a blowout, which is highly dangerous and necessitates immediate replacement. There are various causes for tire tread scrapes, and the severity of damage varies. Even if the damage appears superficial, it might cause the wheel rim to deform under pressure. Therefore, while driving, pay attention to any unusual noises from the wheels or steering wobble.

How to Determine if the Clutch Plate is Worn Out?

Methods to determine if the clutch plate is worn out: 1. Difficulty in shifting gears, with gear grinding during shifts; 2.
