The tire pressure monitoring system has issued an alert. The tire pressure monitoring indicator is a yellow symbol, featuring an irregular circle without a seal on top, with four small spikes at the bottom and an exclamation mark inside. The illumination of the tire pressure monitoring indicator signifies abnormal tire pressure. Abnormal tire pressure is generally caused by the following three reasons: Abnormal tire pressure: Typically, an alert is triggered when the pressure is below 1.8bar or exceeds 3.0bar. At this point, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to illuminate. In this case, simply performing a tire pressure reset will suffice. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged due to impact while driving, it can also cause the tire pressure warning light to turn on. For sensor damage issues, only replacement with a new component is possible.

How to Check Vehicle Owner Information by License Plate Number Online

It is not possible to check vehicle owner information by license plate number online; only the internal police network has access to such data. You can call 114 for vehicle relocation assistance. By providing the license plate number and location of the vehicle that needs to be moved to the operator, the call will be directly transferred to the vehicle owner's mobile phone without revealing their phone number. Alternatively, you can call 122 to request traffic police assistance. 122 is the traffic accident hotline, and by providing the license plate number, the traffic police will locate the owner's information and contact them to move the vehicle. If the vehicle is a new car without license plates, the traffic police will tow the vehicle directly and wait for the owner to contact them. 122 also cannot directly provide the owner's phone number as it is considered personal privacy.

What Does On-Demand Four-Wheel Drive Mean?

On-demand four-wheel drive refers to a system that automatically activates four-wheel drive when the vehicle encounters conditions requiring it, otherwise operating in two-wheel drive mode. Automotive four-wheel drive systems are categorized into full-time four-wheel drive, part-time four-wheel drive, and on-demand four-wheel drive. On-demand four-wheel drive does not require driver intervention. When poor road conditions or wheel slippage are detected, the system automatically engages and redistributes engine torque to the front wheels, seamlessly switching to four-wheel drive. Compared to other four-wheel drive systems, on-demand four-wheel drive has a simpler structure, effectively reducing costs and overall vehicle weight. It is suitable for those needing moderate off-road capability while maintaining fuel efficiency. Precautions for using on-demand four-wheel drive systems: The vehicle will automatically switch from two-wheel drive to four-wheel drive when detecting wheel slippage, active steering, or loss of control. Alternatively, the driver can forcibly engage four-wheel drive via a lock switch, though this method has specific requirements. For example, in the Toyota Highlander, the four-wheel drive mode can only be maintained at speeds below 40 km/h after locking. Some part-time four-wheel drive vehicles cannot use four-wheel drive on hard surfaces, especially when turning, due to the lack of a center differential in the transfer case, which prevents adjustment of front and rear axle speeds.

What is the most effective way to clean a three-way catalytic converter?

The most effective method to clean a three-way catalytic converter is disassembly cleaning, although it is more labor-intensive and time-consuming. This process involves completely removing the three-way catalytic converter from the vehicle, soaking it in a cleaning agent (such as oxalic acid or toilet cleaner) for a period of time, and then rinsing it with clean water. The three-way catalytic converter is an important external purification device installed in the automobile exhaust system. It converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides emitted by vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. The three-way catalytic reactor resembles a muffler, with its exterior made of double-layer stainless steel thin plates forming a cylindrical shape. Between the double-layer thin plates, there is an insulating material—asbestos fiber felt. Inside, a purifying agent is placed between the mesh partitions.

What to Do If a Novice Driver Loses 15 Points in One Day?

You can handle electronic monitoring violation records of 1, 2, or 3 points through the Traffic Management 12123 app, reducing the total points deducted to below 12. Others can wait until the probationary period of their driver's license is over to process the violations. If there is an electronic monitoring ticket that deducts 12 points at once, it also needs to wait until the probationary period is over to be processed. This way, the license will not be revoked, and you only need to retake the theory test (Subject 1). If it's just an electronic monitoring ticket, you can register the vehicle under a family member or friend's driver's license to handle part of the violations, and then use your own license to process the remaining violations. If a driver's license accumulates 12 or more points within a single scoring cycle, the driver must report to the traffic management department of the public security authority at the place where the license was issued or where the violation occurred within 15 days. They must attend a seven-day course on road traffic safety laws, regulations, and related knowledge. Notes on handling violations: One driver's license can only process violations for up to three vehicles, and one vehicle can only be processed by up to three driver's licenses. If a vehicle is recorded with a 12-point deduction at once, a probationary driver's license cannot be used to handle it. Instead, a license that has passed the probationary period can be used to assist in processing, avoiding license revocation. Tickets issued by traffic police on-site or those captured by high-definition cameras showing the driver's face cannot be processed using another person's driver's license; only the violator's own license can be used. This is because the traffic police department will conduct facial recognition to verify the identity of the violator.

Can I still drive if the low tire pressure warning light comes on?

If the low tire pressure warning light comes on, you should not continue driving. Immediately reduce your speed, avoid sharp steering and sudden braking, then stop to check the tires. When the tire pressure warning light illuminates, there are typically four possible causes: 1. The tire has been punctured; 2. The tire pressure is too high; 3. Driving with low tire pressure for an extended period; 4. A malfunction in the tire pressure sensor. If the tire pressure warning light comes on while driving, first turn off the engine, wait 1 to 2 minutes, then restart the vehicle. After the vehicle stabilizes, check the tire pressure values displayed on the dashboard. Both insufficient and excessive tire pressure can trigger the warning light. You can slowly drive to an auto repair shop or detailing shop to adjust the tire pressure. If you have a personal inflation device, you can adjust the pressure yourself.
