When viewed in the rearview mirror, 30cm is roughly the width of two fingers. Below are specific techniques for identifying 30cm: 1. Observe the position of the hood: After hearing the voice prompt, drive forward to the right. When the right front corner of the hood aligns with the roadside line at the 1/3 point, the distance between the car body and the roadside line is exactly 30cm. 2. Look at the raised part of the wiper: From the driver's seat, when the raised part of the wiper aligns with the right-side line, the distance is approximately 30cm. 3. Observe the right front door handle: Check the right front door handle in the right rearview mirror. If the right front door handle is tangent to the right-side line, the distance is 30cm; if it's too far, slight adjustments are needed; if it's too close, there's a risk of crossing the line.

Why Are Used Honda Spirior Cars Cheaper Than Accord?

Because in terms of new car sales, the Accord almost completely outperforms the Spirior. The differences between the Spirior and Accord are as follows: 1. Exterior: The car's appearance is much younger than the Accord. The 2.4L luxury model comes standard with LED daytime running lights and headlights, and the blue body color is quite distinctive. The wheels have been modified by the previous owner to 19-inch aluminum alloy rims, giving it a bit of an aftermarket style. 2. Interior: The car's interior is quite different from the Accord. The entire dashboard has a slightly inclined design, more oriented toward the driver's seat, and the three-spoke steering wheel adds a sportier feel. The one-button start is positioned in the center, with a 7-inch central control screen above it. 3. Central Control: The central control screen has limited functionality, only supporting Bluetooth connectivity, without high-tech features like car networking. The operability is also not strong, though more practical features like radio and music can still be used.

What is the fuel tank capacity of the BYD Qin Plus DM-i in liters?

The fuel tank capacity of the BYD Qin PLUS DM-i is 48 liters, as officially announced. Owners who have purchased the BYD Qin PLUS DM-i can also check this information on the vehicle's configuration sheet. The BYD Qin PLUS DM-i uses 92-octane fuel, with a fuel consumption of 3.8L per 100 kilometers. A full tank can cover a distance of approximately 1,263 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. In actual refueling situations, the amount of fuel filled may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safe fill limit, and there is additional space from the safe limit to the tank opening. This extra space ensures that the fuel can expand when temperatures rise without overflowing the tank. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.

Does Rain Affect a Car Right After Tinting?

Rain does not affect a car right after window tinting, as the film is typically applied to the interior side of the windows. As long as the windows are kept closed, rain exposure is not an issue. However, it is important to note that while rain itself is not harmful, you should avoid rolling down the windows or getting the film wet immediately after application. Below are some relevant points: 1. The environment for car window tinting is crucial. The workspace is usually enclosed, and dust prevention measures should be taken, such as sealing the dashboard and windshield with plastic wrap to prevent airborne particles from contaminating the film. 2. After tinting, avoid rolling the windows up and down. The film tends to be tight initially, and opening/closing the windows can cause the edges to peel or curl, potentially damaging the film. 3. For the first week after tinting, avoid wiping the film. Fogging or haziness may appear on the film, which is normal and will fade over time. 4. After tinting, it is advisable to park the car in a sunny location.

What Causes the Car to Shake When Just Started?

Here are the reasons why the car body shakes when just started: 1. The throttle is dirty or the fuel injectors have excessive carbon deposits. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This causes the car body to shake when just started and makes the vehicle difficult to start. 2. It is recommended to clean the fuel system and check whether the idle speed motor has carbon deposits and clean them off. 3. Check the working condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or weak spark plug firing can also lead to such symptoms. The solution is to check if the spark plugs have excessive carbon buildup and replace them if necessary. 4. If you have already cleaned the engine carbon deposits, cleaned the throttle, replaced the oil seals and spark plugs, but still notice the car body shaking at idle, it is recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor for proper functioning. Abnormal fuel pump supply pressure or incorrect readings and poor performance of the intake pressure sensor can also cause the car body to shake. Also, check the fuel pressure and replace components if necessary.
