What does it mean when the engine energy-saving auto start-stop is not provided?

Here are the relevant explanations: 1. Reasons for the issue: The causes may include insufficient battery charge or winter usage conditions. The auto start-stop system has specific operating temperature ranges and cannot activate when outside these parameters. 2. Auto start-stop function: The engine auto start-stop function automatically shuts off the engine when the vehicle comes to a temporary stop during driving.

What are the free items for a car's first maintenance?

New car first maintenance items generally include changing the engine oil and oil filter. The first maintenance is usually scheduled at 5,000 kilometers or within 6 months, whichever comes first in terms of mileage or time. Since there is a period from the factory to the owner's hands, the engine oil can deteriorate over time, so early maintenance is required. Generally, 4S stores provide free first maintenance. Here are the relevant details: 1. Time for first maintenance: Excluding waiting time in line, normal first maintenance takes about one to two hours. 2. General maintenance items: Common maintenance items for vehicles include engine oil, oil filter, transmission oil, spark plugs, air conditioning filter, air filter, fuel filter, and brake fluid—eight items in total.

The Pros and Cons of Paint Coating for Cars

The benefits of paint coating include scratch resistance, corrosion resistance, no cracking, easy cleaning, anti-static, etc.; the disadvantages are high cost and long construction time. Here are the detailed explanations: 1. Reduced car washing costs and enhanced shine: After a car undergoes paint coating, the crystalline layer protects the car's paint surface. Light dust and small stains can usually be wiped away with a damp cloth, restoring the shine. Moreover, coated vehicles have a higher gloss than new cars, making the entire vehicle look more appealing. 2. Scratch and corrosion resistance: For coated vehicles, the hardness of the crystalline layer far exceeds that of the original car paint, making it difficult for minor scratches to cause damage. It also protects against corrosion from elements like acid rain. 3. High cost and long construction time: Paint coating is significantly more expensive than waxing or sealing, and the construction process is lengthy, usually taking up to two days to complete.
