Is Polishing Required for Waxing?

Waxing requires polishing. The polishing operation process includes: 1. Washing the car to remove iron powder and impurities; 2. Inspecting the entire paint surface to determine the extent of defects such as scratches, oxidation layers, acid rain spots, dust particles, and orange peel; 3. Masking the areas around the regions that require paint surface treatment; 4. Using abrasive compounds to address deep-seated issues affecting the paint surface appearance, such as oxidation layers, streaks, contamination, and fading; 5. Polishing. Polishing refers to the processing method that utilizes mechanical, chemical, or electrochemical actions to reduce the surface roughness of the workpiece, achieving a bright and smooth surface. Polishing involves the use of polishing tools, abrasive particles, or other polishing media to refine the workpiece surface.

Can a Vehicle Be Locked Without Turning Off the Engine?

It is not advisable to lock a vehicle without turning off the engine, even though some models may allow it. When a car remains stationary for an extended period with the engine running, the accumulation of exhaust fumes can potentially enter the cabin through the air intake vents. This poses a serious risk if someone is accidentally locked inside the vehicle. Methods to prevent forgetting to turn off the engine when exiting the car: 1. Check the tachometer and display screen—ensure the display is turned off and dark, and the tachometer reads zero before leaving; 2. Adjust the steering wheel position—avoid setting it too high, as the wheel will rise when the engine is turned off; 3. Use daytime running lights—enable them in the light settings. If the daytime running lights remain off after locking the doors, it confirms the engine is off.

Why Can't the Windshield Washer Fluid Spray Out?

Reasons why the windshield washer fluid can't spray out: 1. The windshield washer fluid has run out, which is usually indicated by a warning light; 2. A burnt-out pump can also prevent the washer fluid from spraying. You can check this by pressing the washer fluid switch—if there's no sound from the pump, it confirms the pump is burnt out; 3. Using tap water instead of proper windshield washer fluid may also cause the fluid not to spray. Tap water contains many impurities, which can form deposits over time, leading to clogged pipes and affecting the lifespan of the reservoir. Additionally, due to the poor lubricating effect of tap water, prolonged use can result in noticeable scratches on the windshield.

Why Are There Few Used Volvos in the Market?

The main reason is that the ownership of this brand in China is relatively low, and its popularity is not high. Depreciation Rate of Volvo: In foreign markets, the depreciation rate of a used Volvo XC60 after five years reaches around 50.1%. However, the situation in China is different, as its resale value is quite low. Similarly, the Volvo S80 does not hold its value well either. Due to the limited number of Volvo models on the road, the convenience of maintenance and repairs is not advantageous, leading to a decline in resale value. Shortage of Maintenance Parts: The reason why Volvos cannot be repaired at most external repair shops is that they lack suitable parts, requiring imports or sourcing from authorized 4S stores.

What does 9-speed manual-automatic transmission mean?

9-speed manual-automatic transmission refers to a gearbox that combines a nine-speed manual transmission with an automatic transmission. A manual-automatic transmission integrates both manual and automatic shifting modes into one system. A conventional automatic transmission typically includes neutral, drive, hill climb first gear, hill climb second gear, and reverse gear. In addition to these, a manual-automatic transmission also provides a function that allows the driver to manually upshift or downshift, usually designated as plus (+) and minus (-) gears. A manual-automatic car possesses the functionality of both manual and automatic transmissions. An automatic transmission includes a manual-automatic transmission, which is a type of automatic transmission that allows for manual gear selection. A manual-automatic transmission does not have a clutch pedal because it is still fundamentally an automatic transmission, and the clutch is not controlled by the driver.
