What to Pay Attention to When Buying a Car

When buying a car, you need to pay attention to confirming purchasing power, key considerations, on-site confirmation, etc. The specific details are as follows: Confirming Purchasing Power: Determine your purchasing power to ensure that buying a car does not affect the overall quality of life for your family. Generally, this is based on the family's average income over the past three years. Typically, 20% of the family's income over three years can be allocated, but it should not exceed 10% of the family's fixed asset value. Key Considerations: For family cars, safety is the most important factor, followed by affordability. Since a car's safety carries the lives of the entire family, safety is the top priority. On-Site Confirmation: Based on the above two steps, narrow down the car models you are interested in. Visit the 4S store in person for on-site confirmation, including test drives, price inquiries, loan options, maintenance, and other related details.

What is the tread depth of car tires?

Tire tread depth standards are as follows: greater than 3.5mm indicates good condition, 2.5~3.5mm is normal condition, less than 2.5mm requires replacement, and the tread must be replaced when it reaches the limit value of 1.6mm. Below is some information about car tire tread depth: 1. National regulations: According to national standards, the wear limit for radial tires used in passenger cars is 1.6mm, while the wear limit for radial tires used in trucks and buses is 2.0mm. Therefore, when the tread of a passenger car wears down to 1.6mm, it must be replaced, and tires used in trucks and buses must be replaced when the tread depth reaches 2.0mm. 2. Inspection methods: Check using the tread wear indicators built into the tire; when the tread wear indicators are flush with the tread surface, the tire needs to be replaced. Alternatively, use a tire tread depth gauge to measure the tread depth.

Why Can't the Car Start After Leaving the Headlights On for 20 Minutes?

The reasons why the car can't start after leaving the headlights on for 20 minutes are as follows: 1. Insufficient Voltage: When the battery voltage is insufficient, the horn and lights may still work, but they cannot power the starter. The battery light will illuminate when the key is in the ON position before starting the engine, indicating low battery voltage. Use a voltmeter to test the battery voltage. If it is below 10V, consider replacing the battery. 2. Poor Fuel Quality: Check the quality of the fuel added to the car to see if it is caused by carbon deposits. If the car has been driven around 20,000 kilometers, focus on inspecting and cleaning the throttle body and checking the ignition switch. Test and inspect the starter, fuel pump, sensors, and other components related to the starting and fuel supply systems. Additionally, after turning on the ignition, wait for 30 seconds to a minute before starting the engine to see if it makes a difference.
