Why Does the Car Make a Hissing Sound When the Air Conditioner is Turned On?

What does the teapot symbol on the dashboard mean?

The teapot symbol on the dashboard is the engine oil pressure warning light. The reasons for its illumination are: 1. Insufficient lubricating oil in the oil pan; 2. Improper adjustment of the oil pressure relief valve; 3. Damage to the lubricating oil filter gasket; 4. Loose connection or rupture of the lubricating oil inlet pipe; 5. Malfunction or damage of the oil pressure gauge or oil pressure sensor; 6. Excessive wear clearance in the crankshaft main bearings, connecting rod bearings, or camshaft bearings. The functions of engine oil are: 1. To reduce friction and wear of moving parts; 2. To remove sludge and varnish from the engine; 3. To neutralize acids produced from fuel and lubricant oxidation; 4. To improve the sealing of piston rings and to cool the engine by carrying away heat from moving parts.

What is the N gear and how to use it?

The N gear in a car stands for Neutral, which can be engaged when waiting at a traffic light. To prevent the vehicle from rolling, you need to keep your foot on the brake. If the waiting time is longer, it is recommended to engage the handbrake, allowing your foot to rest off the brake pedal. N gear: Neutral means 'neutral' and is also called the neutral gear. Many car owners have a misconception that shifting into N gear while coasting downhill or at high speeds can save fuel. In fact, this is a serious mistake, as it not only fails to save fuel but can also damage the transmission. In addition, automatic transmission cars have other gear positions such as P, R, S, D, L, and M. Here is a detailed introduction: P gear: Parking means 'parking.' It is used when parking the car. After reaching the destination or when parking for an extended period, shift the gear lever into this position. Note: The vehicle must be completely stopped before shifting into P gear. Shifting into P gear before the vehicle has fully stopped can damage the automatic transmission. When in P gear, the wheels are mechanically locked, preventing the car from moving forward or backward. Therefore, always engage P gear when parking on an incline. Additionally, during short stops (e.g., at traffic lights), it is best not to shift into P gear to avoid severe transmission damage in case of a rear-end collision. R gear: Reverse means 'reverse.' It is used when reversing the car. To reverse, press the safety button on the gear lever and shift into R gear. However, ensure the vehicle is completely stopped before shifting to avoid severe transmission damage. S gear: Sport means 'sport.' The S gear function provides instant acceleration. In sport mode, the engine runs at higher RPMs, which can help remove carbon deposits. Many automatic cars are equipped with an S gear. In sport mode, the transmission can shift freely, but the shift timing is delayed, keeping the engine at high RPMs for longer periods. This allows the car to maintain low gear and high RPM for extended periods, providing greater torque output and acceleration but consuming more fuel. D gear: Drive means 'drive.' In a car, it is the forward gear. Shifting into this gear and pressing the accelerator allows the car to move. In this gear, the transmission automatically shifts based on speed and throttle conditions. At traffic lights, you can remain in D gear with your foot on the brake. If the wait is short, this is fine, but prolonged waiting can raise transmission fluid temperature and degrade the fluid. L gear: Low means 'low speed.' In a car, it is the low forward gear. When shifted into L gear, the transmission operates only in low gear (equivalent to manual gear 1) and does not automatically shift to other gears based on speed. This gear is typically used for climbing or descending steep slopes. In low gear, the drive wheels output greater torque, providing sufficient power to climb steep slopes. Prolonged braking can overheat the brake pads, reducing braking effectiveness, which is dangerous during long descents or steep slopes. Shifting into L gear allows the engine's low RPM to control the vehicle's movement, eliminating the need for constant braking. M gear: M gear stands for manual mode. After shifting into M gear, the driver can manually control the transmission's upshifts and downshifts. It can be used when climbing or descending slopes or when quick overtaking is needed.

What brand is roadx tire?

roadx is the Roadx tire, a domestic brand under the Sailun Group. It is a new tire brand launched globally by Sailun Group in 2019. In June 2019, Sailun showcased multiple products under its three major brands—SAILUN, ROADX, and MAXAM—at the Dubai Auto Parts Exhibition. Among them, Sailun introduced the new brand ROADX targeting the Middle East and African markets, displaying various flagship products such as AT, MT, run-flat tires, and OTR tires. The brand's market spans over 180 countries and regions worldwide. Sailun has established intelligent tire manufacturing plants in Qingdao, Dongying, Shenyang, Weifang, and other cities. Scope of business for Sailun Group includes: research, production, sales, installation, and related services for tires, rubber products, machinery, molds, and chemical products (excluding hazardous materials); development, sales, and related services for tire production technology software and related technologies; import and export of goods and technology, along with related services; acquisition and sales of used tires; research, production, and sales of tire recycling equipment, materials, and products; development, sales, and related services for tire recycling technology (except for projects prohibited by laws and regulations, and projects requiring permits as per legal restrictions). Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and extreme temperatures during operation. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning ability, along with excellent wear resistance and flex resistance, while maintaining low rolling resistance and heat generation. Tires directly contact the road surface and, together with the vehicle's suspension, help absorb shocks during driving, ensuring good ride comfort and smoothness. They also maintain strong adhesion between the wheels and the road, improving traction, braking, and off-road capability while bearing the vehicle's weight. Roadx tire maintenance methods: Enhance awareness of tire safety and inspect tires regularly. Periodically correct wheel balance, as unbalanced wheels can cause high-frequency vibrations at high speeds, leading to uneven tire wear. Rotate tires regularly to ensure even wear. For every 5,000 kilometers driven, perform a tire rotation. When using Roadx tires daily, pay attention to the following: Regularly check the tire surface for cracks, deformations, or other defects. Due to wear, the tread grooves gradually become shallower. If the tread is worn out, it loses its drainage and anti-slip functions, significantly reducing the vehicle's performance. Small cracks can also pose a risk of blowouts at high speeds. Additionally, promptly remove pebbles lodged in the grooves. Park on level ground whenever possible. Avoid parking on roads with thick, sharp, or pointed stones. Do not park near or in contact with petroleum products, acids, or other materials that degrade rubber. After parking, avoid turning the steering wheel, as this accelerates tire wear. Avoid splashing water to cool tires. In hot weather or during high-speed driving, tires can overheat, increasing air pressure. In such cases, park to allow the tires to cool naturally. Never release air pressure or splash water to cool them, as this can cause abnormal aging of the tread rubber. Avoid sudden braking. Minimize frequent and hard braking to prevent excessive wear from tire dragging on the road.
