Should the Lavida's spark plugs not be replaced unless they are broken?

The spark plugs of the Lavida should not be left unchanged just because they are not damaged. It is recommended to replace them every 40,000 kilometers. Methods to determine if the spark plugs are damaged: Remove the spark plugs and observe them. Check the appearance and color to assess their condition. Normal spark plugs have an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has an insulator skirt that is reddish-brown, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plugs are covered in oil or deposits but are not damaged, they can continue to be used after cleaning off the oil and deposits. If the spark plugs are severely damaged, showing signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plugs with new ones. Additionally, if the spark plugs appear black as if smoked, it indicates that the wrong heat range was selected or that the air-fuel mixture is too rich, with oil seeping up.

Is the Shanghai Electronic Driver's License Recognized by the Police?

Electronic driver's licenses are valid nationwide. Therefore, the Shanghai electronic driver's license is recognized by the police. Additional information is as follows: Using an electronic driver's license: Electronic driver's licenses cannot be used on highways, as highway traffic police are not under local jurisdiction. Therefore, it is still necessary to carry a physical driver's license. The electronic driver's license, commonly known as the "e-license," serves as a supplement to the physical license. In situations where a driver does not carry the physical license, it can still be used for roadside inspections. When traffic police conduct roadside checks and a driver has forgotten to bring the physical license, they are allowed to present the electronic driver's license with a QR code. After verification through a PDA or system to confirm the license's validity, the driver will not be fined or have their vehicle impounded for "not carrying a driver's license or vehicle registration." The electronic driver's license is primarily intended to provide convenience to the public and does not encourage or advocate for not carrying a physical driver's license.

Why was the imported Kia Sorento discontinued?

The customer service for imported Kia is outsourced, and Kia's headquarters has withdrawn, leading to the discontinuation of the imported Kia Sorento. Below is some relevant information about the Sorento: 1. Overall Introduction: From an overall perspective, the Sorento showcases its off-road capabilities through its imposing presence rather than exaggerated local styling. The bold front headlights and distinctly Europeanized body design, combined with well-curved shapes and angular wheel arches, express a harmonious theme of strength and elegance in the vehicle's body. 2. Interior: The interior is equally impressive, mirroring the exterior with its off-road and sporty characteristics. The 'wild' nature is not just superficial but is reflected in practical features. The dynamic and sturdy 4-spoke steering wheel ensures precise control, complemented by aluminum alloy foot pedals.

What to Do When a Motorcycle Won't Start After Getting Wet in the Rain?

If a motorcycle won't start after getting wet in the rain, it may be due to water ingress in certain parts, and the vehicle should be stopped and inspected at this time. The specific steps are as follows: Check for water ingress in the motorcycle: First, remove the air filter and carburetor to check if these parts have water inside. If the air filter and carburetor are dry, then inspect the high-voltage cap, high-voltage wire, spark plug, ignition coil, and other components for water or moisture. Also, check if any circuits have short-circuited due to water ingress. If the issue cannot be identified, it is best to take the motorcycle to a repair shop for inspection and repair. For motorcycles with poorly sealed electrical or fuel systems, it is difficult to avoid this situation in rainy weather, so try to minimize prolonged exposure to rain. Generally, the motorcycle will return to normal once it is completely dry.

How many minutes does it take for illegal parking to be electronically captured?

Generally, exceeding five minutes is considered illegal parking. After a vehicle stops in a no-parking zone, the electronic surveillance will automatically capture a photo. If the vehicle is driven away within five minutes, this photo will be automatically deleted. If the vehicle remains parked for more than five minutes, another photo will be taken and uploaded to the system, constituting a traffic violation. Below is relevant information: 1. When parking outside: It's best to park in designated parking spaces and avoid random parking. If there are no designated spaces on the roadside, it's advisable to park in a paid parking lot, which is more reliable and avoids traffic violations. In daily vehicle use, never park randomly as it may disrupt traffic order and cause congestion. 2. Before heading out: Before going out, check if there are parking spaces available near your destination. If parking is difficult near the destination, consider cycling or using public transportation. It's also recommended to display a contact number for moving the vehicle in case your parked car blocks someone else's. Always adhere to traffic rules, not just to avoid fines or penalties, but for the safety of yourself and others, as well as maintaining traffic order.

Reasons for Severe Odor in Cars After Several Years of Use

Severe odor inside the car can be attributed to the following reasons: 1. Car Interior Materials: A large amount of materials such as plastic, rubber, fabric, paint, insulation materials, and adhesives are used in car interiors, which can emit odors during the car's usage. 2. Damp Air Conditioning: The air conditioning system, being damp and dark, is prone to breeding a large number of bacteria. While the air conditioning works hard for us, it also emits unpleasant odors. 3. Long-standing Items in Corners: Fruit peels or sweets accidentally dropped in the corners of the car can easily rot and mold. Spilled drinks or seats and carpets wet from rain leaks also facilitate mold growth. 4. External Odors: During the operation of the air conditioning, unclean air from outside can be brought into the car, causing odors.
