How many points are deducted for crossing the line during parallel parking in Subject 3?

After parallel parking in Subject 3, if the vehicle body exceeds the right edge line of the road or the sidewalk edge, 100 points will be deducted. Below is a detailed introduction to the point deductions for Subject 3: Point deduction standards for parallel parking in Subject 3: The point deduction standards for parallel parking in Subject 3 are 10 points and 100 points. Turn on the right turn signal while observing the traffic situation behind you through the rearview mirror. After confirming safety, park the vehicle parallel to the curb within 30 centimeters, but do not touch the curb. Stop the vehicle steadily, engage the parking brake, and shift to neutral. After parking, if the vehicle body exceeds the right edge line of the road or the sidewalk edge, 100 points will be deducted; if the distance between the vehicle body and the right edge line of the road or the sidewalk edge exceeds 50 cm, 100 points will be deducted; if the distance between the vehicle body and the right edge line of the road or the sidewalk edge exceeds 30 cm but does not exceed 50 cm, 10 points will be deducted; if the parking brake is not fully engaged, 10 points will be deducted. Precautions for the Subject 3 test: After the candidate completes all required test items and drives a distance greater than 3 kilometers, the system will automatically prompt for parallel parking. Upon hearing the voice command for parallel parking, the student should choose a clear curb (or solid road edge line) on the test route and complete the parallel parking maneuver after confirming safety. After completing the parallel parking, the system will announce the test results via voice.

Do All 4 Ignition Coils Need to Be Replaced Together?

If only one or two ignition coils are faulty, while the others remain unaffected and in good working condition with a service life under 100,000 kilometers, it is not necessary to replace all of them. However, if the mileage exceeds 100,000 kilometers, it is advisable to replace all the ignition coils together. Relevant information about ignition coils is as follows: 1. The core components of the ignition system are the ignition coil and the switching device. Increasing the energy of the ignition coil enables the spark plug to generate a spark with sufficient energy, which is a fundamental requirement for the ignition system to meet the operational demands of modern engines. 2. A typical ignition coil consists of two sets of windings: the primary coil and the secondary coil. The primary coil is wound with thicker enameled wire, usually around 0.5-1 mm in diameter, with approximately 200-500 turns. The secondary coil is wound with finer enameled wire, typically around 0.1 mm in diameter, with approximately 15,000-25,000 turns. 3. Ignition coils are categorized into open-core and closed-core types based on their magnetic circuits. Traditional ignition coils use an open-core design, with the core made of silicon steel sheets about 0.3 mm thick, around which the primary and secondary coils are wound. Closed-core ignition coils feature a core shaped like the Roman numeral III, with the primary coil wound around it and the secondary coil wound outside, forming a closed magnetic circuit with the core.

What does a triangle with an exclamation mark mean in a car?

A triangle with an exclamation mark indicates a malfunction in the car's regular performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: Visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in cars. Besides the triangle with an exclamation mark, there are four other forms of exclamation mark warnings: a yellow gear with an exclamation mark, a red circle with parentheses and an exclamation mark in the middle, a yellow bracket with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four scenarios: Automatic transmission failure: A yellow gear with an exclamation mark indicates an automatic transmission fault warning light, signaling a transmission malfunction or low transmission lubricant. Transmission fluid should be replaced promptly. Brake system failure: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, indicating either a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Tire pressure anomaly: A bracket with a horizontal line and an exclamation mark in the middle represents a tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting failure: A yellow bulb with an exclamation mark is a lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop as soon as possible for inspection and repair, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.

Do Cars Need Car Covers?

Yes, cars need car covers. More information about car covers is as follows: 1. A car cover, also known as a car outer cover, is a protective garment made of cloth or other flexible and wear-resistant materials tailored to the car's dimensions. It serves as a protective accessory for vehicles. 2. Car covers provide excellent protection for the car's paint and windows. In summer, they prevent excessive interior temperatures and avoid scratches from pedestrians or children. 3. Especially for high-end cars, regular use of car covers can extend the lifespan of the paint, keeping it shiny and new. 4. Car covers help outdoor parked cars resist damage from UV radiation, direct sunlight, acid rain, bird droppings, windblown sand, and animal claws.

Do new cars still require a break-in period?

New cars still require a break-in period. Here are the specific details: 1. There are two break-in phases for vehicles. The first phase involves the cold and hot break-in of the engine. Cold break-in refers to the engine being driven by external force to operate and break in, while hot break-in means the engine runs on its own for break-in. These processes are completed at the manufacturer. The second phase is the break-in during the actual operation of the car after the engine is installed, commonly known as the new car break-in. 2. A car consists of many components from different suppliers, and there will inevitably be manufacturing and installation tolerances. Besides the engine mentioned above, the gears inside the transmission also need to break in; otherwise, it could lead to confusion in the transmission's shifting logic. Rubber components and bushings in the chassis also require break-in to prevent noise issues later on. 3. The break-in period for a new car is essentially about reducing the matching errors between various moving parts, allowing them to achieve the optimal working state.

What does AM mean for automatic transmission in large vehicles?

Automatic transmission AM refers to the manual mode. Advantages of automatic transmission: Simple operation and convenient use, easier driving, higher comfort level, better safety coefficient, and more beginner-friendly for new drivers. Advantages of manual transmission: Compared with automatic transmission, it can bring more control pleasure to driving enthusiasts; higher transmission efficiency than automatic transmission, more fuel-efficient than hydraulic automatic transmission under the same engine displacement conditions; simpler structure, cheaper maintenance costs than automatic transmission, and better durability than automatic transmission; relatively mature technology with lower manufacturing costs; higher reliability.
