Lexus is a 'three-good car'. The specific introduction is as follows: 1. Appearance: The new car adopts the latest family design concept, with a more domineering overall shape. The larger X-shaped grille is paired with LED matrix headlights on both sides, creating a stronger visual effect. 2. Interior: The overseas interior spy photos have not been disclosed yet. According to relevant sources, the overall configuration of the new car is more concise and practical. The new leather-wrapped steering wheel replaces the original wooden one, enhancing the sense of luxury. The materials are also more refined, with large areas of soft and transparent leather materials making the interior feel more delicate.

Last time I helped a friend check out a Lexus, and as someone who's been fixing cars for twenty years, I immediately understood why this brand holds its value the moment I popped the hood. The all-aluminum engine paired with a precision hybrid system doesn't even leak oil after 200,000 kilometers. Especially noteworthy are the robust rubber bushings in the chassis—absorbing bumps like premium suit fabric, unlike some German cars that start rattling after three years. The standout is the complimentary maintenance policy: four years or 100,000 km covers even brake pads. I've seen LS owners spend only on windshield fluid over five years. If you plan to keep it long-term, it’s far more cost-effective and hassle-free than European cars at the same price point.

Can You Still Drive with a Small Bulge on the Wheel?

You cannot drive if there is a small bulge on the wheel. Here are the reasons for the bulge: 1. The tire's aspect ratio is too small. Using tires with a low aspect ratio will make them more prone to bulging, increasing maintenance costs and the risk of tire blowouts. 2. Tire pressure issues. Both overinflation and underinflation can cause tire bulging. 3. Impact damage. Hitting obstacles or frequently driving over curbs can easily cause bulging, so you should be more careful in daily driving. 4. The tire has passed its expiration date. We all know that tires have a shelf life and require regular maintenance and replacement, just like engine oil (for engine oil maintenance, choose X-OIL X-Oil), but with a longer maintenance cycle. 5. Quality issues. Accidentally using inferior tires can easily cause bulging.

What does it mean when the EA888 engine reports a too rich system in cylinder 1?

Reasons for the EA888 engine reporting a too rich system in cylinder 1: 1. Issues with the air flow sensor. 2. Not all air passing through the air flow sensor enters the cylinder, some leaks outside the closed system. 3. Damage to the control unit. Below is an introduction to the EA888 engine: 1. The EA888 is a large series with many different engine models, such as CWN, DKU, DKW, etc. The 330TSI engine is the EA888 third-generation B (commonly known as 3.5 generation) engine, while the 380TSI engine is the EA888 third-generation engine. The 3.5 generation engine is superior to the 3rd generation engine, meaning the 2.0T low-power engine is better than the 2.0T high-power engine. 2. The internal forging of the 2.0T low-power engine is different, leading to variations in the strength of certain engine components, such as the crankshaft. The 330TSI is equipped with a 2.0T inline 4-cylinder turbocharged low-power engine, paired with a 7-speed dual-clutch transmission, delivering a maximum power of 137KW and maximum torque of 320N·m. The 380TSI is equipped with a 2.0T inline 4-cylinder turbocharged high-power engine, also paired with a 7-speed dual-clutch transmission, delivering a maximum power of 162KW and maximum torque of 350N·m.

Reasons for Unresponsive RPM After Oil Change

The reason for unresponsive idle speed after an oil change is: changing the oil improves the lubrication inside the engine, reducing wear on internal engine components, which naturally makes the idle less responsive. Generally, the oil needs a break-in period before the RPM stabilizes. The amount of oil replaced in the car should be slightly lower than the mark on the dipstick. Excessive oil increases the crankshaft's rotational resistance, reduces engine output power, and allows the excess oil to enter the combustion chamber, leading to oil burning, blue smoke emission, and increased fuel consumption. When adding lubricating oil, it is advisable to keep it slightly below the dipstick mark. If there is too much oil, the excess can easily enter the combustion chamber (due to excessive internal pressure) and form sticky carbon deposits. Initially, there may be no noticeable effects, but over time, the carbon buildup will worsen, not only causing unresponsive idle but also clogging the catalytic converter's pores, resulting in excessive exhaust emissions (increased fuel consumption). In severe cases, it may even lead to oil burning.

What does the A-circle on the car mean?

The A-circle button on a car refers to the Auto Hold function, which is an extension of the electronic parking brake. Controlled by the ESP component, it manages the braking of all four wheels to prevent the vehicle from rolling. When the car reaches a certain speed and brakes, if the vehicle comes to a complete stop and the brake pedal is held down for 1-2 seconds, the engine will automatically shut off. Releasing the brake pedal and pressing the accelerator will restart the engine. This feature is commonly used at traffic lights to reduce engine idling time, emissions, and carbon buildup. This function is usually paired with an electronic parking brake and is not enabled by default; it requires manual activation. The Auto Hold system is designed to automate the parking brake function. Its basic operation involves the brake management system controlling the four-wheel brakes through the extended functionality of the electronic parking brake. For the Auto Start-Stop function to work, certain conditions must be met: the engine coolant temperature must reach at least 85 degrees Celsius, and the engine oil must also be at operating temperature. The Auto Hold function prevents the vehicle from rolling backward, making it particularly useful on slopes and during frequent stops and starts. The Auto Hold system, together with the electronic parking brake (technically known as the electromechanical parking brake), forms an intelligent braking control system. This integrates temporary braking during driving with long-term parking braking, all controlled electronically. The electronic parking brake uses electronic control to achieve parking braking. Its working principle is similar to that of a mechanical handbrake, relying on friction between the brake disc and pads to control parking braking. However, the control mechanism shifts from a mechanical handbrake lever to an electronic button. This extends the basic parking function to include Auto Hold capabilities. Once the car is started, the Auto Start-Stop function activates. For example, when approaching a traffic light, stopping and holding the brake for 1-2 seconds will automatically shut off the engine. Pressing the accelerator or turning the steering wheel at a green light will restart the engine. In some manual cars, the system determines the need to shut off the engine based on actions like pressing the clutch, shifting to neutral, or pulling the handbrake. The engine restarts when the clutch is pressed again. However, in congested traffic, slow forward movement, parking, or steep uphill driving, it may be advisable to disable this function. Additionally, when using this feature, drivers should remember to turn it off when crossing water to prevent water from entering the engine, which could cause startup failure.

How to Use the D and S Gears in an Automatic Transmission?

In an automatic transmission, the D gear is the forward driving gear, which is used most frequently, while the S gear represents the sport mode. When the D gear is engaged, the vehicle's onboard computer automatically controls the gear shifts based on pre-programmed settings, adjusting gears according to the vehicle's speed and driving conditions. Sport mode is not commonly used and is typically engaged only during overtaking or when driving uphill. Here is an introduction to the gears in an automatic transmission: 1. P (Park): This is the parking gear, used to prevent the vehicle from rolling after parking. 2. R (Reverse): This gear is used for reversing the vehicle, such as when backing into a parking space. 3. N (Neutral): This is the neutral gear, often used in combination with the handbrake when waiting at traffic lights. 4. D (Drive): This is the forward driving gear. When the gear lever is in this position, the transmission automatically shifts gears within the engine's RPM range, with shift points determined by engine load, driving style, and vehicle speed. 5. S (Sport): This is the sport mode of the D gear, providing stronger power output. In this mode, the transmission can freely switch between D and S gears, and gear shifts are delayed to keep the engine at higher RPMs for longer, enhancing vehicle power. 6. L (Low): This is the low-speed mode, often used when descending steep slopes. It functions similarly to engine braking, reducing the load on the braking system.
