What does Front Assist mean?

Front Assist is an urban emergency braking system, also known as a pre-collision safety system, and is not an adaptive cruise control system. This system can be turned on or off through the vehicle's instrument menu. The pre-collision safety system can automatically detect obstacles ahead and calculate the likelihood of a collision. If the system determines that a collision is highly probable, it will emit an alarm sound. The functions of Front Assist include: 1. Real-time monitoring of the distance to the vehicle ahead through a radar sensor installed in the front radiator grille; 2. Pre-processing the brakes in emergency situations and alerting the driver through optical and acoustic warnings as well as brake vibrations to prompt appropriate actions; 3. If the driver does not brake at all, the system will automatically decelerate the vehicle.

What does the yellow exclamation mark light in a car mean?

When a yellow exclamation mark appears on the car dashboard, it can indicate four possible situations: general fault, automatic transmission fault, abnormal tire pressure, or lighting fault. Below is a detailed analysis of these four scenarios: General Fault: An exclamation mark inside a triangle indicates a general performance or component malfunction in the car. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is recommended to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or low transmission fluid level. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark below a horizontal line inside parentheses represents the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. Additionally, a red exclamation mark inside a circle with parentheses indicates a brake system warning, typically signaling a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is necessary to prevent accidents.

Does Clay Bar Damage Car Paint?

Clay bar does not damage car paint. It has the function of removing dirt without harming the surface paint of the vehicle. This is because clay bars are made of ultra-fine fibers and solid colloid through repeated intensive mixing. Characteristics of clay bars: 1. After repeated wiping by car wash workers, it can remove fine pores and spots caused by oxidation on the vehicle body; 2. It can adhere to and remove natural oxidation, water stains, residues from car washing, and improper care on the vehicle body. In mechanical processing, for fine machining, tiny metal residues left on metal surfaces can be removed using clay bars, which is widely applied in precision machining workshops. Additionally, in the automotive repair industry, clay bars are also extensively used in the field of painting.

How to Turn Off Auto-Folding Mirrors

To disable the auto-folding mirror function: Locate the mirror fold control button on the driver's side door panel. Press this button to deactivate the folding feature. The retractable mirror function offers great convenience, allowing the mirrors to fold inward when needed, available in both manual and electric variants. This feature proves particularly useful during parking. Foldable car mirrors significantly save space, especially in parking situations where they help prevent mirror scrapes. Electric folding mirrors provide exceptional convenience - drivers can retract them via interior controls, and the mirrors will automatically unfold upon the next vehicle startup. Note: During winter when temperatures drop, mirrors are prone to ice buildup, so minimize folding operations in cold conditions.

What are the reasons for low tire pressure in cars?

During summer and winter, thermal expansion and contraction cause variations in tire pressure; different loads, whether empty, half-loaded, or fully loaded, result in different tire pressures; severely worn tires and unworn tires also have different pressures. Precautions for tire inflation: Always use a pressure gauge to check the pressure to avoid overinflation, which can cause tire blowouts; after stopping, wait for the tires to cool down before inflating, as driving increases tire temperature, affecting pressure; inspect the valve stem. If the valve stem and core are not properly aligned, with protrusions, indentations, or other defects, inflation and pressure measurement will be difficult. Ensure cleanliness during inflation; the air pumped in must not contain moisture or oil, as these can deteriorate and damage the inner tube rubber. Do not exceed the standard pressure excessively and then release air, nor overinflate due to prolonged inability to inflate while traveling. Excessive pressure can overstretch the cords, reducing their strength and shortening tire lifespan. Before inflating, clean the valve stem of dust and ensure the valve core is not loose. After inflation, apply soapy water (or saliva) to the valve stem to check for leaks (small bubbles indicate leaks), and securely fasten the valve cap to prevent dirt from entering. For radial tires, due to their structure, their sinking amount and contact area are larger, often leading to misjudgment of underinflation and overinflation. Conversely, their naturally larger sinking amount and contact area might make low pressure seem adequate. Use a standard pressure gauge for accurate measurement. The operating pressure for radial tires should be 0.5-1.5 kg/cm² higher than for conventional tires. Both onboard pressure gauges and those used in tire shops should be regularly calibrated to ensure accurate pressure checks.

Will there be any problem if I forget to step on the brake when shifting to P gear?

Forgetting to step on the brake once when shifting to P gear will not have much impact on the car, but doing so for a long time can damage the car's transmission. The correct parking steps should be: 1. Step on the brake to stop the car; 2. Shift the gear to N gear; 3. Tighten the handbrake; 4. Turn off the engine; 5. Shift to P gear. P gear is also called the parking gear, which relies on the power of the engine to brake the vehicle. When the gear is shifted to P gear, there will be a locking gear in the automatic transmission to lock the transmission. Therefore, when shifting to P gear, any movement of the wheels can easily cause the locking gear to break, and even seriously affect the transmission.
