It is not necessary to take a new automatic transmission car on a high-speed run. Below are the methods and precautions for running in a new car: Methods for running in a new car: The best way to run in a new car is to drive it under normal working conditions. Moreover, new cars do not have carbon deposits, so many new car owners take the risk of breaking the law and endangering their lives by deliberately "taking a high-speed run," which is not worth the effort. With the development of the automotive industry, many new cars are now designed with usage factors in mind, and manufacturers clearly state that new cars no longer require running in. Precautions for running in a new car: New cars need timely maintenance during the running-in period. Driving a new car requires the owner to familiarize themselves with aspects such as the car's brakes, accelerator, shock absorption, steering force, and gear-shifting logic. Understanding the car's characteristics is very important for safe driving.

I've been driving automatic transmission new cars for almost ten years, and there's really no need to specifically take them on high-speed runs. I remember when I bought my car, the technicians at the 4S store said that modern engines and transmissions undergo precise testing before leaving the factory, and smooth driving is enough for natural break-in. High-speed runs were practices from the era of older cars, like vehicles from 20 years ago that might have needed highway driving to allow parts to settle, but with advancements in car manufacturing technology today, deliberately taking a new car on high-speed runs can cause unnecessary engine wear and increase fuel costs. Automatic transmission cars are designed to shift smoothly, and the usual stop-and-go city driving or occasional highway commuting is sufficient for break-in. Safety comes first; during the break-in period of a new car, just avoid sudden acceleration, fully loaded steep hill climbs, or prolonged high RPMs. Following the owner's manual recommendations for gentle driving during the first 1,000 kilometers saves money, reduces hassle, and is environmentally friendly.

I just bought a new automatic car and also looked up information about running-in at high speeds online. The conclusion was that there's no need to do it deliberately. After chatting with a few car enthusiast groups, they all agreed that modern cars aren't that delicate, and normal driving can achieve the running-in effect. The technician at the 4S store told me that taking a new car on the highway consumes more fuel and time, and may also increase emissions, which isn't environmentally friendly. For automatic cars, just accelerate steadily on the highway and avoid flooring the gas pedal suddenly, and everything should be fine. The key is to drive gently during the running-in period, allowing the engine and transmission to adapt to driving habits. I suggest not bothering with high-speed running-in; saving on fuel costs and investing in maintenance is more practical. Anyway, after a month of commuting in the city, my car is in great condition, fuel consumption has decreased, and I haven't encountered any issues.

What is the reason for no air from the rear air conditioning in a Lexus?

If there is no air from the rear air vents, it may be due to a valve malfunction. If the exhaust valve is open but no air is coming out, it is highly likely that the valve is faulty. Another possibility is leakage at the connection between the evaporator case and the air duct. Additionally, a dirty or clogged air filter in the car's air conditioning system can block the air vents. When a car is driven for long periods in poor air quality, the air filter is more prone to becoming clogged with debris. Tips for maintaining car air conditioning: 1. Do not randomly adjust the direction of the air conditioning vents: When using the air conditioning, not paying attention to the direction of the airflow can reduce its effectiveness. According to the principle that cold air sinks and hot air rises, the correct approach is to direct the vents upward when using the air conditioning for cooling and downward when using it for heating. 2. Regularly start the air conditioning in winter: In regions with milder winters, some car owners may not use the air conditioning at all during the winter. Prolonged disuse can cause the rubber seals to age and the lubricants on internal components to dry out. Starting the air conditioning periodically allows the components to be lubricated and maintains their good condition. Therefore, it is advisable to start the air conditioning at least once a week during winter.

What is the working principle of Lexus hybrid?

When starting the engine, you will notice an unusual quietness, with no engine noise audible at all. In fact, the engine has not yet begun to operate, and the central console display clearly shows the engine's working status. After starting the car, the electrical system inside the vehicle is activated. During low-speed starts, the engine does not need to be engaged at all; the electric motor, powered by the energy stored in the battery, can effortlessly move the car out of the parking space. The level of quietness throughout the vehicle is truly unimaginable. More relevant details are as follows: 1. Electric Motor: When preparing to depart, the engine remains off, and the two electric motors onboard begin to provide the power needed to move the car out of the parking space. With a slight press on the accelerator, such as when going uphill, the engine is immediately awakened, and the slight engine noise allows you to experience the surge of power. At this point, both the engine and the electric motor work together to propel the vehicle. Simultaneously, part of the engine's power is diverted to the generator set, which promptly charges the battery. 2. Cruising: When the vehicle is cruising at low speeds, since the battery has stored sufficient electrical energy, the system will automatically shut down the engine based on the vehicle's speed, allowing the electric motor to directly drive the vehicle forward, thereby achieving fuel savings.

What causes the car not to move in D gear but works normally in R gear?

It could be an issue with the forward gear or a damaged solenoid valve for the forward gear signal from the computer. Below are specific causes and solutions: 1. Forward gear teeth grinding: Gear grinding essentially refers to the hard contact between two metal gears, accelerating the wear on the gear teeth. Solution: A major transmission overhaul is required. 2. Damaged solenoid valve for forward gear signal: You may noticeably feel the car struggles to start. Although pressing the accelerator speeds up while driving, there's no obvious sign of acceleration. Solution: Promptly visit a professional and reputable repair shop for inspection and add transmission oil to ensure better lubrication of the transmission gears.

What is the fastest speed for an F1 tire change?

The fastest speed for an F1 tire change is 1.88 seconds. Here is a brief introduction about tires: 1. Basic information: Tires are ring-shaped elastic rubber products mounted on various vehicles or machinery to roll on the ground. In 1845, R.W. Thomson, a civil engineer born in Scotland, invented the pneumatic tire and obtained a patent from the British government under the title 'Improvement in Carriage Wheels and Other Vehicles.' On December 10 of the same year, the first pneumatic tire was born. Tires are usually mounted on metal rims to support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the vehicle's driving performance. 2. Required conditions: Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high and low temperatures during operation. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, they are also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.
