The methods to identify China IV or China V vehicles are as follows: 1. For vehicles that have already received the environmental protection inspection qualification mark, the emission standard can be viewed on the original or duplicate of the environmental protection inspection qualification mark. Alternatively, you can log in to the Motor Vehicle Environmental Protection Website and enter the vehicle model and engine model in the New Vehicle Compliance Query System. 2. According to the national plan, the China VI emission standard is scheduled to be implemented on July 1, 2020, only three years after the full implementation of the China V standard. In some key regions, such as the Beijing-Tianjin-Hebei region and surrounding areas, the Yangtze River Delta region, the Fenwei Plain, the Pearl River Delta, and the Chengdu-Chongqing region, the China VI emission standard will be implemented ahead of schedule. 3. Compared to the current China V standard, the China VI standard raises the threshold by nearly 50%, and it is slightly higher than the current international strictest emission limit—the Euro VI standard. After the official implementation of the China VI standard, it will become the strictest motor vehicle emission standard in the world.

As an ordinary car owner, I mainly check the emission standards in these ways: Open Alipay on your phone and search for 'Motor Vehicle Environmental Protection Inquiry', then enter the last six digits of the VIN to get the result; the second page of the big green book (vehicle registration certificate) clearly states whether it's China IV or China V; the vehicle conformity certificate that comes with the car also contains emission standard information. Another simple method is to check the license plate registration time - plates registered in the south before 2017 are mostly China IV, while new cars nationwide after that are basically China V. Remember to avoid scammers when checking these, as some places can alter records for money - I've been tricked before. Also, don't trust the stickers on the windshield after the environmental protection labels were canceled, as they might be outdated.

What to Do When Car Tires Lock Up?

To solve the problem of car tires locking up, install ABS. Cars equipped with ABS continuously monitor the speed of each wheel or drive shaft through speed sensors installed on them during emergencies. The vehicle's computer calculates the wheel slip rate and the required braking force at that moment, making decisions on braking pressure to ensure the tires do not lock up. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high and low temperatures while driving. Therefore, they must have high load-bearing capacity, traction performance, and cushioning performance, as well as high wear resistance and flex resistance, along with low rolling resistance and heat generation.

What does EBA on a car mean?

EBA on a car stands for Emergency Brake Assist system. During emergency braking, the sensor on the brake pedal detects the action and sends the signal to the vehicle's computer, which then increases the braking force to a higher level. EBA can sense the degree of demand the driver places on the brake pedal. In some very urgent situations, drivers often cannot press the brake pedal quickly enough, and EBA is designed for such cases. When EBA detects that the driver is pressing the brake pedal rapidly and forcefully, the computer analyzes the situation and, if it determines it to be a sudden emergency, reacts and calculates the urgency level extremely quickly, immediately providing additional pressure to the pedal to enhance the braking effect.

Where is the rearview mirror heating button on the Teana?

The rearview mirror heating button on the Teana is the same as the rear window defogging button, located on the air conditioning panel, and can be activated simultaneously. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rain or fog, eliminating the need for the driver to frequently wipe the mirror manually, thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is needed, as there is an adjustment button on the driver's side. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within a few minutes, typically between 35-60 degrees. Heat is then emitted from both left and right rearview mirrors. Simultaneously, as the temperature rises and evaporates, water droplets on the mirror surface become smaller, and fog gradually dissipates, effectively clearing frost and condensation. However, if the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves electric heating wires embedded in the mirror, which consume a significant amount of power. Ensure the car is running when using this function to avoid draining the battery, which could prevent the car from starting. Other methods for defogging rearview mirrors include: Opening windows slightly to allow air circulation between the inside and outside of the car, reducing the temperature difference and gradually clearing fog. Adjusting the car's air conditioning to the appropriate setting to blow warm air for defogging.
