What is the reason for water dripping under the car after parking in summer?

Does Half Fuel Gauge Mean Half Tank?

Half fuel gauge does not mean half tank. It is less than half tank. Here are several methods to reduce fuel consumption: 1. Start slowly. When starting the vehicle, use a low gear, gently press the accelerator, and gradually increase speed. 2. Light acceleration, light braking, and early braking. While driving, press the accelerator lightly, avoid sudden increases in engine speed, and prevent the car from shaking during driving to make the car more fuel-efficient. 3. Maintain proper tire pressure. Keep the tire pressure at the level recommended by the manufacturer. 4. Regularly organize the trunk to reduce weight. Frequently check if there are unnecessary items in the trunk. 5. Close the windows. Driving with windows open increases wind resistance, and greater wind resistance means more resistance for the car, requiring more power and thus increasing fuel consumption. 6. Regularly maintain the vehicle or perform inspections. Timely oil changes can reduce carbon buildup. 7. Replace fluids on time. Change engine oil and transmission fluid regularly.

What is a Pre-tensioner?

Pre-tensioner introduction is as follows: 1. The pre-tensioner tightens the seat belt during the initial phase of moderate to severe frontal collisions, near-frontal collisions, or rear-end collisions. 2. For vehicles equipped with side-impact airbags and roof curtain airbags, the seat belt pre-tensioner can assist in tightening the seat belt during side collisions or rollover accidents. The control devices for pre-tensioning retractors are divided into two types as follows: 1. Electronic control device. The electronic control unit (ECU) detects abnormal changes in the vehicle's acceleration, processes the signal through the computer, and sends it to the retractor's control device to activate the pre-tensioning device. This type of pre-tensioning seat belt is usually used in combination with auxiliary airbags. 2. Mechanical control device. The sensor detects abnormal changes in the vehicle's acceleration, and the control device activates the pre-tensioning device. This type of pre-tensioning seat belt can be used independently.

Why is it not recommended to install tire pressure monitoring for new cars?

Most new cars basically come with original tire pressure monitoring devices, and some models even have tire pressure warning devices. Tire pressure monitoring is not a real-time monitoring function. If there is an abnormality in the tire, information will be automatically displayed on the dashboard. The displayed content does not have specific values, only indicating which tire has a problem. The working principle of tire pressure monitoring is: Using pressure sensors installed in the tires to measure the tire pressure, and using wireless transmitters to send the pressure information from inside the tire to the central receiver module. How to eliminate the tire pressure alarm: There is a tire monitoring indicator button on the central console. After the system issues a low tire pressure warning, the car must remain stationary for about one minute. Do not move the car or turn off and restart the ignition switch until the button is pressed to recalibrate the tire monitoring indicator. Find the tire pressure reset option in the settings on the central display. If none of the above methods work, you need to go to a 4S shop to eliminate the tire pressure alarm. What to do if the tire pressure is insufficient: If no damage is visible, you can directly inflate to the normal tire pressure and reset the tire pressure system. If the tire is found to be punctured during inspection, you need to drive to a tire shop promptly for repair and then reinflate. If the tire pressure is still indicated as insufficient after inflation for a while, but there is no puncture in the tire, it may be due to air leakage caused by wheel hub deformation. It is recommended to check the wheel hub and replace it.

What items are included in a car first aid kit?

A car first aid kit mainly contains dressing supplies such as elastic head covers, buckle-type tourniquets, elastic bandages, etc., sterile dressings like gauze, bandages, disposable gloves, etc., and tools such as first aid scissors, medical tweezers, safety pins, and life-saving whistles. Precautions for car first aid kits: 1. Ensure proper sealing: The items in the car first aid kit must be properly sealed, especially waterproofing. Once water gets in, the first aid supplies will certainly be affected and may even become unusable, which could be problematic in an emergency. 2. Regularly check expiration dates: If medications are unused for a long time, make sure to check their expiration dates. Expired items should be promptly discarded and never reused, as this could worsen the situation rather than alleviate it.

Is the right side too narrow when reversing into the parking space due to late or early steering?

There are two scenarios when the right side becomes too narrow while reversing into the parking space: 1. If it's a left-side reverse parking, the steering was too late. 2. If it's a right-side reverse parking, the steering was too early. There are two main methods for reverse parking: 1. "Non-character style" reverse parking. In this method, the vehicle is perpendicular to the target parking space, using the B-pillar as a reference point and the first parking space as a marker, you can generally reverse into the third parking space. This positioning method is more suitable for novice drivers, with the advantage of being relatively easy to complete in one attempt if mastered well, but the drawback is being somewhat mechanical. 2. "Straight-line" parallel parking. In "straight-line" parallel parking, you use the vehicle in front as a reference, align your car body, turn the steering wheel to the right, and when the angle between the two cars reaches 45 degrees, observe and straighten the wheel while reversing. With proper estimation, you can usually complete the parking in one attempt.

Why does the wiper keep making noise?

There are several reasons why the wiper keeps making noise: 1. Fine streaks, fog, or linear residues appear on the glass. Foreign objects are attached, such as sand particles or dust on the triangular edge, or the edge is damaged. Clean the edge or replace the wiper blade. 2. The swing is not smooth, and the wiper jumps abnormally. The edge of the wiper blade is bent or wavy, or there are residues like wax or oil film on the glass surface. Wipe the glass clean or replace the wiper blade. 3. The contact surface of the rubber cannot fully adhere to the glass surface, resulting in wiping residues. After prolonged use, the rubber hardens, loses elasticity, or becomes damaged. Replace the wiper blade. 4. The glass surface shows a water film state after wiping. The wiper arm is deformed due to rust or external force. Replace the wiper.
