Causes and solutions for abnormal noises when accelerating are as follows: 1. Fuel pump motor noise: When the fuel pump motor is worn or contaminated with impurities, it may produce abnormal noises upon acceleration. This issue requires replacing the fuel pump. 2. Throttle body noise: Modern throttle bodies are electronic, controlled by a motor for opening and closing. Worn motor gears can lead to insufficient engagement, causing noise. Excessive carbon deposits and sludge in the throttle body can also result in abnormal sounds. Cleaning the throttle body may resolve this, but a damaged motor necessitates throttle body disassembly and servo motor replacement.

How to Check the Production Date of Pirelli Tires?

The production date of Pirelli tires can be found on the sidewall, as detailed below: 1. Key Points to Note: When replacing tires, it's crucial to check the production date marked on the tire. The production date is typically represented by a four-digit number, where the first two digits indicate the week of production, and the last two digits represent the year. For example, "3512" means the tire was produced in the 35th week of 2012. 2. Shelf Life: The shelf life of a tire is generally 5 years. When replacing with new tires, the production date should not be older than 3 years (the closer the production date, the better, as it means a longer usable period within the shelf life). However, tires do not indicate an expiration date, only the production date. 3. Recommendation: If the production date is unclear, it's advisable not to purchase the tire to avoid buying overly old stock or refurbished tires. Additionally, it's best to choose authorized repair shops or installation points designated by the tire manufacturer for replacement.

Why does the tire pressure light come on when driving on the highway?

When the tire pressure light suddenly comes on while driving on the highway, it indicates an issue with the vehicle's tire pressure. In such a situation, it is advisable to safely pull over to a suitable location, turn on the hazard lights, and inspect the tires. If you have a tire pressure monitoring tool, you can check the pressure of all tires to ensure they are within the normal range. Hazards of overinflated tires: Reduced friction and adhesion, affecting braking performance; Causes steering wheel vibration and misalignment, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance, making tires more susceptible to damage from sharp objects like nails or glass, leading to internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and misalignment, compromising driving safety; Increases movement of tire components, leading to abnormal overheating due to excessive rolling; Weakens cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength, which may lead to blowouts at high speeds; Increases tire deformation, leading to sidewall cracks, excessive heat generation, rubber aging, cord fatigue, and accelerated shoulder wear due to increased contact area.

How Long Does a Car Stay in a 4S Store Before It's Considered Inventory?

Inventory cars in 4S stores generally refer to vehicles that have been in stock for more than three months without being sold. Here are some key points to consider when purchasing a car: 1. Confirm Purchasing Power: Determine your purchasing capacity to ensure that buying a car won't affect your family's overall quality of life. Generally, it's recommended to allocate no more than 20% of your family's average income over the past three years, but not exceeding 10% of your family's fixed asset value. 2. Safety: For family cars, safety is the most important factor, followed by affordability. Since a car's safety carries the lives of your entire family, it should be the top priority. 3. On-site Confirmation: Based on the above two steps, narrow down your choices to a few models and visit the 4S store in person to confirm details such as test drives, pricing, loan options, and maintenance services.

What does it mean when the license plate light warning light comes on?

When the license plate light warning light comes on, it indicates a malfunction with the license plate light, and a yellow bulb warning light will appear on the dashboard. The car's license plate light is used to illuminate the license plate at night or in low-light conditions, along with other small position lights, and is located above the rear license plate. Below are the correct methods for using car lights: 1. Poorly lit roads: Use high beams on roads without streetlights or with poor lighting. However, switch to low beams when approaching other vehicles or pedestrians to avoid glare. 2. Checking road signs: When unfamiliar with the road and needing to check signs or markers, high beams can be used but should quickly be switched back to low beams. 3. Overtaking: Turn on the left turn signal in advance and alternate between high and low beams or use the horn to alert the vehicle ahead to yield. 4. Approaching corners, curves, or unsignalized intersections: Alternate between high and low beams as a warning. 5. Driving in tunnels: Use high beams but switch to low beams when encountering oncoming traffic. 6. Urban areas with streetlights at night: Always use low beams in well-lit city areas. 7. Dark areas without streetlights: Use low beams when driving in unlit areas at night or during dusk or dawn. 8. Obstructed visibility: In heavy fog, snow, or rain where visibility is poor, use low beams even during the day.
