How Should Beginners Observe Rearview Mirrors While Driving?

Here are the methods for beginners to observe rearview mirrors: 1. Central rearview mirror: Adjust it so that you cannot see your own car in the mirror, and position it vertically with the distant horizon in the center of the mirror. 2. Left side mirror: The correct position for the left side mirror is when the body of the car occupies one-fourth of the mirror's width in the horizontal position, and adjust the vertical position accordingly. 3. Right side mirror: When adjusting the vertical position of the right side mirror, two-thirds of the mirror's surface should show the ground. Below are the installation positions of rearview mirrors: 1. Interior rearview mirror: The interior rearview mirror allows the driver to confirm the situation behind without significantly changing the forward line of sight while driving. 2. Exterior rearview mirrors: Passenger cars generally mount the exterior rearview mirrors on the doors. 3. Undercarriage mirror: The undercarriage mirror enables the driver to see areas beyond the front and rear wheels under the car's body through the mirror directly in front of the driver's seat. It helps the driver see if there are people or obstacles near the wheels or beside the car when reversing or starting forward, preventing injuries, damage to objects, and vehicle harm, providing convenience and safety to the driver.

Why is the idle speed high during cold start?

Cars have high idle speed during cold start for the following reasons: 1. High idle speed during startup is normal: (1) The car needs high speed to make the engine reach normal working conditions as soon as possible, requiring a richer mixture, so the intake air volume and fuel injection volume will increase, resulting in higher speed. (2) Increased oil viscosity during cold start: During cold start, the idle stepper motor automatically adjusts to increase the intake air volume, allowing more air to enter the cylinder, so high idle speed is normal. 2. Excessive carbon deposits: Timely cleaning of the throttle and idle motor can generally solve this problem.

What is the speed limit on highways?

The speed limit is 110 km/h, and there are also speed limits of 80 km/h, such as in tunnel sections and mountainous highways, as well as a speed limit of 120 km/h, but these are mostly on multi-lane highways in plain areas. Below are the penalties for speeding based on relevant laws and regulations: According to the actual traffic conditions on highways and the functionality of speed monitoring equipment, the Traffic Police Corps of the Public Security Department stipulates that speed monitoring equipment captures violations based on vehicle-type-specific speed limits, namely: 1. Small passenger vehicles exceeding 120 km/h (excluding 120 km/h) on Hainan Province highways will be automatically captured by speed monitoring equipment; 2. Other vehicles besides small passenger vehicles exceeding 100 km/h (excluding 100 km/h) on Hainan Province highways will be automatically captured by speed monitoring equipment. 3. Small passenger vehicles speeding within 50% (180 km/h) on highways will be fined 200 yuan, while severe traffic violations exceeding 50% (over 180 km/h) will be fined 1,000 yuan and may also result in license revocation; 5. Other vehicles besides small passenger vehicles speeding within 50% (150 km/h) on highways will be fined 200 yuan, while severe traffic violations exceeding 50% (over 150 km/h) will be fined 1,000 yuan and may also result in license revocation.

How to Maintain Car Paint?

There are several main methods for maintaining car paint: 1. For the first wash of a new car, it is best to go to an indoor dust-free hand wash facility or a well-maintained car wash. Some contaminants are not visible to the naked eye, such as tree sap, alkali, acid, and other chemical pollutants, which should be thoroughly removed. 2. Do not wax a new car casually, as the paint layer of a new car already has a protective wax coating. Waxing too early can remove the original wax on the new car's surface, causing unnecessary waste. Generally, there is no need to rush to wax a new car within three months of purchase. 3. Regularly inspect the car body, engine hood, and surrounding areas. If any scratches are found, they should be promptly addressed at a professional detailing shop.

What does it mean when the engine yellow light is on in a Chevrolet Malibu?

Chevrolet Malibu engine yellow light may be on due to the following reasons: 1. Sensor issues: The sensors include coolant temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain engine data, which will cause the engine warning light to illuminate. 2. Intake problems: The engine requires air intake during combustion, and the air filter plays a crucial role in this process. If the car's air filter is dirty and not cleaned regularly, it can affect the air intake. Over time, this may lead to blockage, and in severe cases, it can cause the engine warning light to turn on. 3. Poor combustion of the air-fuel mixture: Faulty spark plugs, ignition coils, fuel pump, or clogged fuel lines can all lead to poor combustion of the air-fuel mixture in the engine. Poor combustion results in engine carbon buildup or knocking issues, which are eventually detected by the engine's oxygen sensors and reported to the ECU, triggering the warning light. 4. Maintenance issues: Poor engine maintenance is the most common cause of the engine warning light turning on. 5. Fuel and oil quality issues: This refers to both fuel and engine oil. The fuel used in cars usually has a specific octane rating, and engine oil can be semi-synthetic or fully synthetic. Manufacturers generally recommend which type of fuel and oil to use. If the owner does not follow these recommendations, long-term use can lead to engine wear.
