The reasons for the air conditioning not cooling in the car are: 1. Insufficient or too little refrigerant; 2. Excessive refrigerant; 3. Loose drive belt of the car air conditioning compressor; 4. Unqualified refrigerant and refrigeration oil; 5. Moisture infiltration into the refrigeration system. Solutions for the air conditioning not cooling in the car: 1. Add refrigerant; 2. If there is too much refrigerant, slowly release some from the low-pressure side maintenance port of the air conditioning system; 3. Replace the drive belt with a new one; 4. Re-inject an appropriate amount of refrigerant. The air conditioning in the car is used to adjust and control the temperature, humidity, air cleanliness, and air flow in the car compartment to an optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue.

What does Toyota's 10-speed CVT transmission mean?

Toyota's 10-speed CVT transmission means: The Toyota 10-speed CVT transmission is essentially a combination of what is referred to as an ECVT transmission and a 4AT transmission, forming ten gears. The ECVT is quite similar to an AT transmission; rather than being just a transmission, it is more like a highly complex drivetrain system, typically used in Toyota's hybrid models. In this 10-speed CVT transmission, the ECVT provides three fixed gear ratios, which are combined with the first three gears of Toyota's 4AT transmission to form gears 1 through 9. The highest gear of the 4AT then matches the highest gear of the ECVT, creating the tenth gear. The Toyota 10-speed CVT can be seen as a hybrid product of a 4AT and an ECVT.

Is It Necessary to Install Seat Covers on Car Leather Seats?

It is not necessary to install seat covers on car leather seats. Here are some relevant details about leather seats: 1. Leather seats are more stain-resistant and easier to maintain compared to regular fabric seats. With proper care, such as promptly cleaning any stains, leather seats can last for 5-8 years. 2. Seat covers may interfere with the deployment of side airbags. From a safety perspective, seat covers are not recommended. This is because many modern seats are equipped with side airbags, which are usually installed in the side bolsters of the seat. 3. In the event of a side impact, side airbags are not designed to penetrate an additional layer of seat cover, which could prevent them from deploying properly and significantly reduce their protective effectiveness. If you must use seat covers, ensure that the seats are not equipped with side airbags or purchase seat covers that do not interfere with airbag deployment.
