The car button 'ion' refers to the vehicle's negative ion air purification function. When this function is activated, the negative ion generator produces and releases a large number of negative ions. Since dust, particles, and harmful substances like formaldehyde in the air can easily adhere to these negative ions, they form larger particles and settle down. These particles are then filtered out by the air filter, effectively purifying the air inside the car. The negative ion air purification function is typically available in higher-end vehicle models. For vehicles equipped with this function but lacking a physical 'ion' button, the feature is usually integrated into the central control screen. By accessing the air conditioning interface on the screen, you can clearly see the 'ion' touch button.

The functionality of car buttons is a topic I'm frequently asked about. As a seasoned driver with years of experience, I'd say each button is like an old friend accompanying you in the car. For instance, the air conditioning button—press it and cool air blows out, making summer drives super comfortable. The defogger button is a lifesaver on rainy days or winter mornings, instantly clearing the front windshield to prevent blurred vision. The lighting buttons include headlights, fog lights, and high/low beam switches—using high beams at night on highways helps you see farther. Then there's the hazard warning button; in case of an accident, pressing it makes all lights flash to alert following vehicles to stop safely. Every time I get in the car, I habitually check these buttons to ensure they respond promptly, avoiding unexpected malfunctions. Regularly cleaning dust off button surfaces or consulting the manual to learn specialized functions like cruise control boosts driving confidence. Ultimately, remember: if you're unsure, don't press randomly—ask someone knowledgeable or visit a repair shop for an explanation. Safety always comes first.

What insurances are essential when buying a car?

When purchasing a car, it is essential to buy four types of auto insurance: compulsory traffic insurance, third-party liability insurance, no-deductible insurance, and vehicle damage insurance. The only mandatory insurance required when buying a car is compulsory traffic insurance. Compulsory traffic insurance is a mandatory insurance in China, and all vehicles must purchase this type of insurance. In the event of a traffic accident, the insurance company can only compensate the party that was hit, meaning the conditions for compensation are relatively limited. Additionally, if compulsory traffic insurance is not purchased, the vehicle will lose its eligibility for annual inspection.
