Tire pressure monitoring sensors can be installed in different locations, which can be divided into built-in and external types. The built-in sensor is installed inside the tire, which is relatively more stable. The external type involves adding a sensor outside the valve stem. Below is an introduction to tire pressure monitoring: 1. The tire pressure monitoring device is a simpler tire pressure monitoring system that utilizes the existing sensing function of ABS to compare the rotation counts of the tires. A tire with insufficient pressure will have a shorter circumference, so if one of the four tires has insufficient pressure, its rotation count will differ from the others while driving. 2. The built-in sensor is installed inside the tire, which is relatively more stable, and the temperature data monitored will be more accurate. 3. The external type involves adding a sensor outside the valve stem, which is easy to install and can be done in minutes. However, there is a temperature monitoring difference of 2-3 degrees compared to the built-in type.

How to Add Windshield Washer Fluid to a Volkswagen Passat?

Here are the 4 steps to add windshield washer fluid to a Volkswagen Passat: 1. Use the wiper control knob to first drain the existing washer fluid. 2. After spraying out all the old washer fluid, add a small amount of newly prepared washer fluid to the washer fluid reservoir. 3. Turn on the wiper switch again to clean out the remaining old washer fluid solution. 4. When no more fluid sprays from the nozzles, add approximately 4L of washer fluid, then securely close the cap to complete the process. Additional Information: 1. Never add coolant antifreeze or similar additives to the windshield washer fluid. This can create an oily film on the windshield, severely impairing visibility and increasing the risk of accidents! 2. If the windshield wipers are left on when the ignition is turned off, they will resume operation in the same setting when the ignition is turned back on. If there is frost, snow, or other obstructions on the windshield or rear window, this may damage the wipers or wiper motor. 3. If the system fails to spray fluid, first check if the washer fluid level is too low, then inspect whether the washer pump is faulty.

Is a new passenger car exempt from inspection for 2 years?

Although new vehicles fall under the 6-year inspection exemption policy, national regulations still require owners to apply for an annual inspection sticker at the vehicle management office every 2 years. Inspection conditions: Vehicles whose actual condition does not match the information recorded on the license and registration files, vehicles with damaged/incomplete license plates or registration certificates, illegible text, or self-made license plates. Inspection precautions: No exterior modifications are allowed. The tint of sunshade/anti-explosion window films cannot be too dark (interior items should be visible from one meter away - mainly applies to vans and trucks; not strictly enforced for passenger cars with ≤5 seats). Vans and trucks must display enlarged rear license plate numbers. The number of leaf springs cannot be altered. The seating capacity of vans cannot be increased or decreased. A fire extinguisher is required. No modifications are allowed to box truck compartments (no side doors, no roof openings, no tailgates). Tire sizes cannot be changed, and tread patterns must be consistent on each axle. Vehicles with outstanding traffic violations or court impoundments cannot undergo inspection.

How to Check Tire Pressure on Volkswagen Tiguan?

Volkswagen Tiguan checks tire pressure by starting the engine. Here are the relevant introductions about tire pressure: 1. When there is a significant difference between a leaking tire and the stored tire pressure, an alarm will be triggered: The dashboard will display the icon on the SET button. The Tiguan uses an indirect tire pressure monitoring system, which is not very intuitive and does not allow real-time tire pressure queries. The Tiguan comes standard with a tire pressure monitoring system, which is indirect in form and officially called TPR by Volkswagen. 2. It relies on analyzing data from the four wheel speed sensors to determine whether a tire is leaking: After inflating the tires, press the initialization button SET in front of the gear lever and continue driving for three kilometers. The system will record the tire pressure condition. If it detects that the tire pressure is 20%-30% below the standard value, the indicator light on the dashboard will illuminate. Similar to the Roewe 550, it cannot provide accurate information such as the specific tire position.

How much over the speed limit is acceptable on national highways?

National highways do not allow speeding, and any speeding on national highways is considered a traffic violation. Speeding reduces the driver's ability to judge speed: When driving at high speeds, drivers not only misjudge the speed of their own vehicle but also underestimate the speed of pedestrians, bicycles, and other vehicles. This can lead to misjudging the speed and distance of oncoming vehicles when overtaking, as well as underestimating the distance required to overtake the vehicle ahead. Often, reactions are delayed, increasing the risk of collisions or side-swipe accidents. Speeding decreases the driver's reaction time: When speeding, the frequency of overtaking and encountering oncoming traffic increases, reducing the distance between vehicles. The driver is overwhelmed by the rapid changes in the external environment, consuming significant mental and physical energy. Frequent shifts in attention can lead to fatigue and, over time, drowsiness, greatly increasing the likelihood of accidents.

What labels need to be affixed to a new car?

There are two labels that need to be affixed to the front windshield of a new car: the motor vehicle inspection compliance label and the compulsory insurance label. Both labels must be placed in the upper right corner of the vehicle's front windshield. If the driver has held a driver's license for less than one year, a probationary driver sign must also be affixed to the rear of the vehicle. Below is relevant information about vehicle labels: 1. Legal requirements: Article 11 of the Road Traffic Safety Law of the People's Republic of China stipulates that when driving a motor vehicle on the road, the vehicle must display license plates, display the inspection compliance label and insurance label, and carry the vehicle registration certificate. 2. New 2019 label regulations: Previously, three labels - the motor vehicle inspection compliance label, compulsory insurance label, and environmental inspection compliance label - were all mandatory and had to be displayed on the front windshield. However, under the new regulations, the environmental inspection compliance label has been abolished, and only the motor vehicle inspection compliance label and compulsory insurance label are now required.

What is the difference between Castrol EDGE Start-Stop and Castrol EDGE?

The difference between Castrol EDGE Start-Stop and Castrol EDGE is that Castrol EDGE Start-Stop is a fully synthetic lubricant, while Castrol EDGE is only semi-synthetic. Due to the different types, although both have the same API rating of SN, the price of Castrol EDGE Start-Stop is significantly higher than that of Castrol EDGE. Advantages of Castrol: The main advantages of Castrol are its excellent cold-start performance, providing protection even before starting, better wear resistance compared to other engine oils, and effective reduction of engine noise. However, its cleaning capability is not as good as that of Shell and Mobil products in the same category, and the oil degrades relatively quickly. It can be seen that different brands of engine oils have their own strengths and weaknesses, with some focusing on cleaning performance and others on high-temperature wear resistance. Precautions for using synthetic engine oil: It is important to note that in extreme weather and environmental conditions, it is recommended that car owners use fully synthetic engine oil. For example: extremely cold regions, dusty areas, severely humid regions, and high-temperature areas can all impose significant stress and damage on the engine.
