When the vehicle is stationary, the driver's static field of vision is approximately 200 degrees. The relationship between vehicle speed and field of vision is as follows: When the speed increases from zero to 40km/h, the dynamic field of vision is about 100 degrees. When the speed increases to 80km/h, the dynamic field of vision is about 60 degrees. When the speed increases to 120km/h, the dynamic field of vision is only about 30 degrees. Generally, when the speed is below 50km/h, drivers can still clearly distinguish objects in front and on both sides. Generally speaking, as the speed increases, the dynamic field of vision narrows, and the clear observation distance shortens and moves forward. Therefore, it is advisable not to speed. Precautions for safe driving: Do not press the accelerator pedal forcefully before the engine coolant low-temperature warning light goes off. Insufficient heating can lead to abnormal combustion of unburned gases and damage the three-way catalytic converter. Before driving, always ensure all doors are closed, as unclosed doors may suddenly open during driving, causing serious accidents. If any door is not properly closed, a door ajar warning will appear on the dashboard. When snow or fallen leaves accumulate at the air intake under the front windshield, remove them promptly. Otherwise, fresh air cannot be drawn in, leading to insufficient ventilation inside the vehicle. During rain, the temperature inside the car rises, causing fog to form on the windows, which can impair the driver's vision.

Is Intake System Cleaning Necessary?

Intake system cleaning is necessary. Cleaning the intake system can effectively eliminate issues such as unstable engine idling, shuddering, and poor acceleration, improve intake performance, restore normal air-fuel ratio, reduce fuel consumption and emissions, and lubricate intake system components to prevent rust and corrosion. The consequences of not cleaning the intake system are as follows: 1. Fuel is directly sprayed from the injector onto the intake valve, forming carbon deposits under high temperatures. Carbon deposits on the intake manifold and intake valve absorb fuel before it enters the combustion chamber, making the fuel leaner and causing the intake valve to close improperly, leading to stalling or shuddering; 2. Carbon deposits in the intake system reduce air flow and disrupt the critical air-fuel ratio; 3. This results in poor idling, reduced power, increased fuel consumption, and higher emissions.

How to Install a Rearview Camera for Car Backup?

The installation steps for a car backup camera are as follows: 1. First, connect the power cable of the backup camera to the car charger and route the camera's wiring from the rear seat to the back of the car. 2. Then, use a screwdriver to remove the decorative panel in the trunk. 3. Choose the optimal location for the backup camera installation and secure it, usually near the license plate light. 4. Finally, connect the camera's wiring to the positive terminal of the tail light and reassemble all removed components. Here is some relevant information about car backup cameras: A car backup camera is a system designed to provide drivers with a clear and intuitive view of the rear and sides of the vehicle, greatly enhancing convenience. It allows drivers to monitor the video feed of the surroundings in real-time, helping to prevent accidents and theft.

How many days can it take to check if you were caught speeding on the highway?

Highway speeding violations can typically be checked within 3 working days. Below are specific details about highway speed limits: 1. Speed limits: On two-lane highways, the leftmost lane has a speed limit of 100-120 km/h, while the middle lane is 60-100 km/h. For three-lane highways, from left to right, the speed limits are 110-120 km/h, 90-110 km/h, and 60-90 km/h respectively. 2. Regulations: Strictly adhere to highway speed limit regulations to avoid accidents caused by speeding. Driving too slowly can also hinder normal traffic flow. During rainy or snowy conditions, driving speeds should be appropriately reduced. 3. Maintaining distance: Under normal conditions with dry roads and good braking, the distance between vehicles (in meters) should not be less than the numerical value of the speed (in km/h).

What does the sawtooth pattern on both sides of the white line on the highway mean?

Highway white lines with sawtooth patterns on both sides indicate that lane changes are not permitted in this lane. Below are specific details about highway lanes: 1. Speed limits: On two-lane highways, the leftmost lane has a speed limit of 100-120 km/h, while the middle lane is 60-100 km/h. For three-lane highways, from left to right, the speed limits are 110-120 km/h, 90-110 km/h, and 60-90 km/h respectively. 2. Regulations: Strictly adhere to the highway speed limit regulations to avoid accidents caused by speeding. Driving too slowly can obstruct normal traffic flow. During rainy or snowy conditions, drivers should reduce their speed accordingly. 3. Maintaining distance: Under normal conditions with dry road surfaces and good braking performance, the following distance (in meters) should not be less than the numerical value of the speed (in km/h). Always pay attention to roadside distance indicator signs.

Will speeding displayed on highway LED screens result in penalty points?

Speeding displayed on highway LED screens will not result in penalty points, as it primarily serves as a warning. Below are precautions for driving on highways: 1. Overtaking: Exercise extreme caution when overtaking on highways. Always use turn signals before overtaking and pass from the overtaking lane. Avoid developing the bad habit of overtaking from the right side. Do not immediately overtake after signaling; also pay attention to road conditions behind you. When overtaking conditions permit, accelerate and maintain a 1.5-meter lateral distance from the vehicle ahead. 2. Maintaining longitudinal distance between vehicles: Under normal circumstances when the road surface is dry and braking conditions are good, the distance between vehicles (in meters) should not be less than the numerical value of the speed (in km/h). For example, maintain at least 80m at 80km/h and at least 100m at 100km/h. Always pay attention to roadside distance marker signs. During rainy, foggy, snowy, or wet road conditions, the distance between vehicles should be more than doubled.

What type of engine oil should be used for the Leiling 1.2T?

Leiling 1.2T recommends using 0W-20 engine oil. Turbocharged engines are best suited for fully synthetic mineral oil with high viscosity, which aids in lubrication between engine components. The choice of engine oil should be flexible based on actual conditions, as illustrated in the following two scenarios: 1. If going to a 4S shop, opt for fully synthetic oil of SM grade, with SN grade being the best, such as Golden Mobil or imported GT oil. 2. Oil grades: 0W-20, 5W-20, 5W-30, and 10W-30: API SL grade "Energy-Conserving", SM grade "Energy-Conserving", or SN grade "Resource-Conserving", or ILSAC multi-grade engine oil 15W-40 and 20W-50: API SL grade, SM grade, or SN grade multi-grade engine oil.
