Reasons why the reversing radar doesn't beep: 1. Improper or damaged wiring connection: If the rear of the car is close to an obvious obstacle but the reversing radar doesn't respond at all, it indicates an issue with the radar's wiring. 2. Low sensitivity and slow response: Sometimes, even when you can see the obstacle in the rearview mirror, the reversing radar fails to recognize it and only beeps when very close, which is due to the radar's poor quality. 3. There is a blind spot at the far left and far right of the reversing radar: When this blind spot is about to touch an obstacle, the reversing radar cannot detect it. The reversing radar, also known as 'reverse collision avoidance radar' or 'parking assist device,' mainly consists of ultrasonic sensors, a controller, and a display.

Has the Oil Emulsification Issue in Toyota Avalon Been Resolved?

Avalon's oil emulsification issue has been resolved. Below is a detailed introduction to the Yellow Shell engine oil: 1. Types: There are two types of Yellow Shell engine oil, one is HX6, which is SM grade, a semi-synthetic oil, but with less synthetic base oil content compared to Blue Shell. The other is HX5, which is SL grade, a mineral oil. 2. Differences: The smaller the number before the W, the better the low-temperature fluidity of the oil. For engine oil labeled 10w-40, W stands for winter, and the number 10 before W represents the freezing point temperature. The freezing point temperature for 10W oil is -25°C. The number after W represents the kinematic viscosity of the oil at 100°C, with higher values indicating higher viscosity.
