Do You Need to Lift the Car to Replace the Oil Filter?

Replacing the oil filter requires lifting the car. The oil filter is designed to remove debris, gum, and moisture from the engine oil, delivering clean oil to various lubrication points. To reduce friction between moving engine components and minimize wear, oil is continuously supplied to the friction surfaces, forming a lubricating film. The steps for replacing the oil are as follows: 1. Run the engine until it reaches operating temperature. Then, use a jack to lift the vehicle, engage the handbrake, and secure the front wheels with wooden wedges. 2. Drain the oil. Locate the oil drain plug underneath the vehicle, unscrew it, and allow the oil to flow out. Observe the oil color—normal oil should be translucent, while blackened oil indicates the need for immediate replacement. 3. Unscrew the oil filter. Once the oil flow slows, remove the oil filter for secondary drainage. Removing the filter can be challenging and requires a specialized filter wrench. Ensure all residual oil in the compartment drains completely. 4. After all the oil has drained, replace the oil filter. Use the filter wrench to install the new filter, tighten it, then securely fasten the drain plug. Finally, lower the vehicle.

What is the solution for the Volkswagen CC sunroof rattling noise?

Volkswagen CC sunroof rattling noise may be caused by friction between the sunroof and the roller shade metal parts. Applying some grease or sticking tape on the friction areas of both the sunroof and roller shade metal parts can eliminate the noise. Here is some related information: 1. The Volkswagen CC is equipped with an electric sunroof, measuring 420mm in length and 740mm in width, with a daylighting area of approximately 0.31 square meters. Although it is not a panoramic sunroof, it is fully sufficient for daylighting and ventilation. 2. The sunroof can be opened upwards. When the weather is good, opening the sunroof for ventilation prevents direct wind exposure. The Volkswagen CC's sunroof is quite distinctive, designed as a half-roof sunroof based on the vehicle's styling. The front half of the entire roof is a large glass sunroof. Due to the Volkswagen CC's inherently low vehicle height design, there is no space in the roof to accommodate the sunroof track, so only the front half can be opened, while the rear half cannot. If forcibly opened, the sunroof would hit the head of rear passengers.

Can ETC still be used if the card is removed?

If the card is removed, the ETC device cannot be used. According to the "Rules for the Use of Non-Stop Rapid Transit Systems," the ETC card must be inserted into the OBU device for normal operation; otherwise, user information cannot be read. If the card is removed, you can use the manual lane and have the staff swipe the card. When the ETC card is inserted into the OBU device, there will be a prompt sound, indicating that the device is activated. Without the card inserted, the device remains in a dormant state and cannot recognize vehicle information at toll stations. Therefore, ETC cannot be used if the card is removed. ETC is an electronic toll collection system, also known as an automatic road toll system. It is a specialized road toll method used for toll roads, commonly seen on highways, toll bridges or tunnels, and some urban road sections to alleviate traffic congestion. ETC Deduction Principle: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, the system uses computer networking technology to settle accounts with banks, enabling vehicles to pay tolls without stopping at the toll station. All of this is based on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improved efficiency: ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, intercity transportation cards will be widely interoperable in key urban clusters, and the proportion of vehicles equipped with ETC will significantly increase." The plan also sets a target of "achieving a 50% ETC usage rate for road passenger vehicles by 2020." Future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will include promoting ETC use for trucks and exploring deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-road coordination, and other smart transportation developments. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage.

What does 185/60r15 mean?

185/60R15 specific meaning: 185 indicates the cross-sectional width in millimeters. 60 represents the aspect ratio, meaning the section height is 60% of the width, and 15 denotes the rim diameter in inches. More details about tires are as follows: 1. Types of tires: The internationally standard tire code expresses the section width and aspect ratio as a percentage in millimeters. This is followed by: tire type code, rim diameter (inches), load index (permissible load-bearing mass code), and permissible speed code. For example, in 175/70R1477H, 175 means the tire width is 175MM, 70 indicates the tire's section aspect ratio is 70%, meaning the section height is 70% of the width, the rim diameter is 14 inches, the load index is 77, and the speed rating is H. 2. Passenger cars generally use radial tires. The specifications of radial tires include width, aspect ratio, inner diameter, and speed limit symbol. It is particularly important to note the aspect ratio, which refers to the percentage of the tire's sidewall height to its width. Modern passenger car tires mostly have aspect ratios between 50 and 70. The smaller the number, the flatter the tire shape. To ensure sufficient load-bearing capacity and improve driving stability and grip, the width of tires and rims has to be continuously increased. As a result, the cross-sectional shape of tires has evolved from an approximate circle to a flattened ellipse. The lower the tire's aspect ratio, the smoother the tire runs and the stronger the handling. However, the ride may feel less elastic, with more noticeable vibrations. Some cars have already adopted tubeless radial tires, commonly known as 'atomic tires.' These tires are less prone to heat buildup during high-speed driving. If punctured by a nail or sharp object, they leak slowly, allowing the vehicle to continue driving for a certain distance.

Where to Check the Manufacturing Date of Tires?

The manufacturing date of tires can be found on the outer sidewall of the tire. The outer side of the tire has several important features. For most tires, the outer side is marked with the English word "outside," while the inner side is marked with "inside." If these words are not present, you can also distinguish the outer side by the red solid dot and yellow hollow dot on the tire sidewall—these dots indicate the outer side of the tire. On the outer side of the tire, there is a four-digit number in an elongated oval shape following the letters "DOT." The first two digits represent the week of the year, and the last two digits represent the year. For example, "3511" means the tire was manufactured in the 35th week of 2011. In addition to the manufacturing date, tires also display the following common data: Tire type code, rim diameter (in inches), load index (permissible load mass code), and permissible speed code. For example, in "175-70R14-77H," 175 represents the tire width in millimeters, 70 indicates the aspect ratio (the height of the tire's cross-section is 70% of its width), R stands for radial tire, 14 is the rim diameter in inches, 77 is the load index, and H is the speed rating. Tire carcass ply material: Indicated by Chinese pinyin, such as M for cotton ply, R for rayon ply, N for nylon ply, G for steel ply, and ZG for steel radial ply tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters A to Z represent certified speed ratings ranging from 4.8 km/h to 300 km/h. Common speed ratings include: Q: 160 km/h; H: 210 km/h; V: 240 km/h; W: 270 km/h; Y: 300 km/h. During daily use of tires, pay attention to the following points: Regularly inspect the tire surface for cracks, deformations, or other defects. Due to wear from driving, the tread grooves gradually become shallower. If the tread is worn flat, it loses its ability to drain water and provide traction, significantly reducing the vehicle's performance. Small cracks can also pose a risk of tire blowouts at high speeds. Additionally, promptly remove stones lodged in the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that can deteriorate rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Do not splash water to cool overheated tires. In hot weather or during high-speed driving, tires can overheat, increasing air pressure. In such cases, stop to let the tires cool naturally. Never release air to reduce pressure or splash water to cool the tires, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent or hard braking to prevent accelerated tread wear from dragging against the road surface.
