Above ground. Additional information is as follows: 1. Choose a high and open area: During heavy rain, it is recommended to park the vehicle above ground rather than in an underground parking lot, preferably in a high and open location. 2. It is advisable to cover the vehicle with a car cover: When parked outside during heavy rain, the car's paint surface can be corroded by rainwater, leading to water marks, oxidation, or even cracking. Rainwater can also seep into the seams of the vehicle body, causing metal parts to rust and corrode. 3. Be cautious of slippery roads after heavy rain: Wet and slippery roads require careful driving during rainy days, but one should also remain vigilant in underground parking lots, as vehicles entering from outside can bring in rainwater and make the ground wet.

Parking during heavy rain is a test of choice. As an experienced driver who has been on the road for many years, I've learned that it's all about weighing the risks. Underground parking shelters the car from rain and flying debris, preventing raindrops from damaging the paint. However, areas with poor drainage can suffer from severe water accumulation. Once, my car was parked in an underground garage when the drainage pump failed, nearly flooding it. Parking on the surface offers better ventilation, but accumulated rainwater can soak the wheels or attract branches that may damage the car, posing significant safety hazards. My advice is to check the weather forecast and parking facilities: if the underground parking has a new drainage system, prioritize it; for surface parking, choose higher ground to avoid flooding. Never overlook safety checks—repair costs for water-damaged cars aren't cheap. Overall, underground parking is more reliable, but you must ensure its dependability.

As an automotive technology enthusiast, parking during heavy rain requires meticulous analysis. Underground parking provides shelter, reducing rainwater erosion on car paint and electronic components, thereby extending vehicle lifespan; however, if the garage drainage fails or is designed in a low-lying area, water accumulation depth can far exceed ground level, posing greater risks. Surface parking, while offering better air circulation, exposes the vehicle to higher elemental risks such as wind-blown debris or water damage to the chassis. Key inspection factors include evaluating garage drainage hole functionality, pumping system condition, and entrance waterproofing capability; surface parking location selection should consider wind and rain shelter. Prioritize underground parking if facilities are well-maintained; otherwise, opt for elevated ground areas for safety. Pay extra attention to parking environment selection during routine maintenance.

Are there any clothing requirements for driving practice?

It is advisable not to wear skirts during driving practice. Below are some clothing considerations for driving practice: Simple attire: Keep it simple and neat, and wear sports shoes. The clothes you wear while learning to drive should be simple and neat. Avoid clothing with accessories, as they or any loose strings might get tangled with the steering wheel, making it difficult to operate. Wear sports shoes during practice to prevent accidentally pressing the pedal all the way down or slipping. Female drivers are advised to tie up their hair to avoid obstructing their vision, including any bangs that might get in the way. Things to note during driving practice: During practice, it's important to understand and apply what you learn, using your brain as much as your hands. Driving practice isn't just about physically operating the vehicle; it's also about mentally processing the techniques.

Can the car's clear coat be repaired?

Yes, the car's clear coat can be repaired, but it should be done at a professional auto repair shop or 4S store. A car's paint consists of four layers, from the inside out: the electrocoating layer, the primer layer, the color coat layer, and the clear coat layer. Clear coat repair process: First, clean the area where the clear coat has peeled off with a cloth, then use toothpaste to thoroughly clean the spot. Next, apply paint matching the car's body color using a touch-up pen, layering it slowly and carefully. After repainting, the paint does not fully adhere immediately. Washing the car during this period can damage the clear coat surface, reducing the paint's adhesion. For paint maintenance, consider visiting a professional auto detailing franchise for a glaze or coating treatment. Both glazing and coating fill tiny holes or uneven surfaces on the paint, forming a protective layer. For the vehicle's underside, applying an underbody coating or sealant can protect against acid rain and corrosion, preventing the original protective layer from cracking or peeling. Precautions: After sandstorms, avoid using a duster or cloth to wipe off dust; instead, rinse with water to prevent scratches from sand particles on the tools. For minor rust, use very fine wet sandpaper with water to gently remove rust spots. After cleaning thoroughly, apply a layer of primer. For new scratches, clean and apply primer directly. If you have a small can of the original paint, wait for the primer to dry, sand it smooth, and then apply the original paint over the primer. If original paint isn't available, use a touch-up pen for coloring. For new small scratches, applying regular toothpaste lightly can reduce the mark and act as a temporary barrier against rust.

Why is the Cayenne's engine yellow light constantly on?

Cayenne's engine yellow light constantly on for the following reasons: Sensor issues: Including water temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine fault light to come on. Maintenance issues: Poor engine maintenance is the most common cause of the engine fault light coming on. If the owner does not perform regular maintenance, coupled with poor driving habits, it will increase the burden on the engine operation. Oil quality issues: The oil quality mentioned here includes fuel and engine oil. If the owner does not add gasoline as required, it will cause engine wear over time.
