When it starts to rain, the rainfall is light, and the sky is relatively dark, but visibility is still good. At this time, you should use the width indicator lights. Rainwater itself can obstruct your vision, and water on the road surface can be kicked up by the rolling tires of the vehicle in front, significantly affecting visibility. Tail lights inherently have excellent penetration; generally, heavy rain cannot block their light, and rear fog lights are extremely bright. Driving in the rain without lights makes it difficult to judge the position, distance, and speed of the vehicle behind. If the vehicle in front changes lanes or turns without clear conditions, it can easily lead to a rear-end collision accident.

I always pay special attention to the use of lights when driving in the rain, especially after decades of driving experience. The first thing is to turn on the low beam immediately after starting the vehicle, which not only improves your own visibility but also makes it easier for others to see you and avoid rear-end collisions. When the rain gets heavier, I turn on the front and rear fog lights, but I’m careful not to use high beams too often because the reflection off raindrops can make it harder to see the road. Additionally, keeping the lights clean is crucial—after the rain, muddy windshields can affect light effectiveness, so timely wiping ensures clarity. Relatedly, checking tire grip is also essential, working in tandem with proper lighting to ensure a safer drive and prevent skidding accidents. In short, using lights wisely significantly reduces the risks of rainy-day driving—it’s all about forming good habits.

How to Solve the Squeaking Noise from Plastic Interior Trim?

Squeaking noise from plastic interior trim can be resolved by: adding a layer of velvet cloth strip in the gaps, installing rubber strips between the dashboard and windshield gap can also reduce some noise. It's important to note that repeated disassembly and reassembly of the interior can also cause squeaking, so first check if there are any loose or fallen wiring harnesses or small parts causing the issue. Below is an introduction about car interior: Definition: Car interior mainly refers to the automotive products used for internal modifications, covering all aspects of the car's interior, such as steering wheel covers, seat cushions, floor mats, car perfumes, hanging accessories, interior decorations, storage boxes, etc. Status: The car interior system is a crucial part of the vehicle body, and the design workload of the interior system accounts for over 60% of the total vehicle styling design workload, far exceeding the exterior design, making it one of the most important parts of the vehicle body.

Will the Car Be Damaged If Water Gets into the Trunk?

Water in the trunk can have a significant impact on the car, and failure to address it promptly may lead to malfunctions. Below is a detailed explanation: Dangers of water entering the trunk: It can easily cause rust in the trunk, and in severe cases, perforation may occur. The spare tire is placed in a lower position inside the trunk, making it prone to water accumulation if water enters. Moisture and water cannot be drained, which can easily cause the car's interior parts to become damp, moldy, or rusty. How to handle water in the trunk: Drain the water as soon as possible. There is a rubber plug at the bottom of the spare tire compartment in the trunk; removing it allows the water to drain. Quickly locate the entry point of the water, check if the trunk lid is deformed, or if the surrounding seals are damaged. Open the lid to ventilate, remove the trunk lining and items inside, and leave the lid open to dry for about an hour to prevent mold and rust.

Is it a problem if there is water under the car seat?

If there is water under the car seat, it is recommended to check whether the air conditioning pipe of the car is leaking. Generally, problems with the car's air conditioning pipe can cause such a phenomenon. Here are some reasons for water inside the car: Rainwater entering through the windshield: It is possible that the windshield was not closed properly, allowing rainwater to enter during rainy weather, resulting in water under the seat. Make sure to close the windows properly to avoid water ingress. Poor door sealing: If the rubber seals are not installed correctly, repeated closing and squeezing of the doors can cause the seals on both sides to deform, leading to poor sealing of the car. In severe cases, this may even cause water to enter the car during rain. Sunroof leakage: The sunroof is sealed with a rubber seal. During use, it is important to pay attention to dust prevention for the seal, especially in winter or after long-distance travel. Regularly clean the seal with a duster. Additionally, it is crucial not to force open the sunroof when it is frozen, as this can damage the sunroof motor.

Will the car battery die if the car is not driven for a month?

Will the car battery die if the car is not driven for a month? The answer is yes. Here are the factors that affect battery discharge. Factors related to parking duration: The duration a battery can be left unused depends on its self-discharge rate. Due to inherent impurities in battery materials, power loss occurs whether the battery is in use or not. At room temperature, approximately 1% of charge is lost per day. When installed in a vehicle, the battery supplies current to maintain vehicle functions such as the central control computer and central door locks even when stationary. This standby current is referred to as "parasitic drain," and its magnitude varies depending on the vehicle's configuration. Other factors: High-end vehicles feature automatic wake-up functions. When activated by external influences, the current can reach several amperes and may take several minutes to return to sleep mode. The battery voltage level is not the sole determinant of whether the vehicle can start; it is also directly related to the vehicle's condition and ambient temperature.

Should motorcycle maintenance be done personally or at a shop?

Motorcycle maintenance can be handled either personally or at a shop, and those with strong hands-on skills can do it themselves. Below are the relevant details about motorcycle maintenance: Changing engine oil and oil filter: For newly purchased motorcycles, the break-in period is 2,000 kilometers. The engine oil should be changed once at 500 kilometers and again at 2,000 kilometers. After the break-in period, the oil should be changed every 2,000 kilometers during normal operation. Replacing the air filter element and routine inspections: The air filter element should be cleaned once a year. Daily maintenance includes keeping the vehicle clean, maintaining proper tire pressure, and ensuring the battery is fully charged.

Should the Air Conditioning Evaporator Be Cleaned?

The air conditioning evaporator needs to be cleaned regularly, otherwise, a lot of bacteria can grow inside. Specific details are as follows: Cleaning frequency for the evaporator: The air conditioning evaporator should be cleaned once a year depending on the situation. An endoscope can be used for inspection, and if the evaporator is found to be dirty, it should be cleaned promptly. Cleaning the evaporator helps improve the efficiency of the air conditioning system, enhances cooling performance, and is equivalent to saving fuel consumption for the car. Precautions for cleaning the evaporator: Visualized cleaning is recommended, which requires specialized equipment. It is advisable for car owners to have it cleaned at a professional cleaning shop. Avoid using acidic substances and try to use weakly alkaline solution mist to prevent severe oxidative corrosion to the heat exchanger.
