Do You Need to Use Turn Signals for Reverse Parking in Subject 2?

Using turn signals is not required for reverse parking in Subject 2. Here are the relevant details: Instances where turn signals are needed in Subject 2: 1. Immediately after parallel parking, turn on the left turn signal, then drive out onto the road and turn it off. 2. Right after stopping on the slope, turn on the left turn signal, drive over the crest, and when the steering wheel is turned back 90 degrees, the turn signal will automatically turn off. Key steps for reverse parking: 1. Reversing into the parking space from the starting point: After adjusting the seat and mirrors and fastening the seatbelt, shift into reverse, release the parking brake, and let the car move backward at idle speed. Observe the parking space through the right rear window. When the black edge of the right rear window aligns with the right boundary line of the parking space, turn the steering wheel fully to the right. 2. Driving from the parking space to the turnaround point: Shift into first gear and drive out of the parking space. When the hood approaches the road boundary line, turn the steering wheel fully to the left and stop once the car is straight. 3. Reversing into the parking space from the turnaround point: Shift into reverse, keep the steering wheel turned fully to the left, and reverse. Observe the left rearview mirror and adjust the steering to guide the rear of the car into the space. Once inside, check the right rearview mirror. When the entire right boundary line of the parking space is visible, straighten the steering wheel. Then, look at the left rearview mirror and stop when the left door handle aligns horizontally with the base line of the parking space. 4. Driving from the parking space back to the starting point: Shift into first gear and drive out of the parking space. When the hood approaches the road boundary line, turn the steering wheel fully to the right and stop once the car is straight.

Is coasting in neutral or in gear more fuel-efficient for manual transmissions?

For carburetor-equipped vehicles, coasting in neutral saves fuel, while for fuel-injected vehicles, coasting in gear is relatively more fuel-efficient. Here are the relevant explanations: 1. Carburetor vehicles: Carburetor vehicles rely on engine suction to create a vacuum that draws fuel into the intake manifold. The gasoline adheres to the manifold walls and mixes with air before entering the cylinders, where it is compressed and combusted to perform work. Therefore, idle speed is the lowest operating speed. Coasting in neutral is equivalent to the engine being in an idle state, and the longer this state lasts, the more fuel is saved. 2. Fuel-injected vehicles: Fuel-injected vehicles use a computer to calculate the fuel injection amount based on parameters such as intake air volume and temperature. The system divides operation into eight conditions: starting, post-start, warm-up, idle, partial load, full load, transition, and overrun. When the computer determines that the vehicle is in the overrun condition based on throttle opening and engine speed, if the speed is above a certain value and the throttle idle switch is closed (indicating an idle state), it begins to retard the ignition timing to reduce output, then stops fuel injection, although the spark plugs continue to operate.

What is the Difference Between the Internal and External Circulation of a Car's Air Conditioning?

The difference between the internal and external circulation of a car's air conditioning: 1. Symbols for internal and external circulation: The internal circulation symbol is a circular arrow inside the car graphic; the external circulation symbol is an arrow entering the car from outside. 2. Operation methods of internal and external circulation: In internal circulation, air only circulates inside the car without exchanging with the outside air; in external circulation, the air inside the car is connected with the outside air, with outside air flowing in from the front intake and out from the rear exhaust. The use of internal and external circulation should be flexible, chosen based on the driving environment: 1. During traffic jams: Use internal circulation for the air conditioning, as external circulation would draw exhaust fumes from outside into the car. 2. General air conditioning cooling: Use internal circulation to quickly lower the temperature inside the car. Once the temperature stabilizes, appropriately switch to external circulation to exchange air with the outside. 3. Cooling the car after outdoor exposure to sun: First use external circulation for the air conditioning, and you can also open the windows to speed up heat dissipation. After a few minutes, close the windows, switch to internal circulation, and turn on the cooling.

Is Car Antifreeze Universal?

Car antifreeze is not universal. It is best not to mix antifreeze (coolant) from different brands and models to avoid failure due to differences in chemical composition. How to choose antifreeze: The basic indicators of antifreeze are freezing point and boiling point. The freezing points of antifreeze available on the market include -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one with a freezing point at least 10°C lower than the lowest temperature in your region. Precautions for replacing antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leakage or cracks in the pipes, with a focus on the five-way water pipe. The five-way pipe gets its name from having five connections to different parts. Antifreeze flows through the five-way pipe and is then distributed to different parts of the car to function. If there is any sign of antifreeze leakage in this part, the water pipe should be replaced or the connection should be re-secured based on the situation.

What does 'Application in Progress' mean in the driving test?

It means the appointment has not been successfully scheduled yet and is still under processing, requiring patience to wait. Below is relevant information about the driving license test: 1. Subject 1: Refers to the examination on road traffic safety laws, regulations, and related knowledge. 2. Subject 2: Refers to the examination on field driving skills. 3. Subject 3: Refers to the examination on road driving skills. 4. Subject 4: Refers to the examination on road driving skills and safe, civilized driving common sense. 5. Legal aspects: According to Article 31 of the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses,' theoretically, after passing Subject 3, one can immediately schedule the Subject 4 exam without any required waiting period.

What Are the Reasons for a Car Engine Not Starting?

Check if the battery voltage is too low: You can turn on the headlights and some electrical devices to observe whether there are noticeable changes in the brightness of the dashboard and interior lighting during the starting process. If they dim, it indicates insufficient battery voltage. Excessive carbon buildup in the intake pipe: Too much carbon buildup on components like the throttle valve and idle speed motor can prevent the engine's air-fuel mixture from reaching the required ratio, making the vehicle unable to start. This can also cause repeated engagement of the magnetic solenoid and starter relay, resulting in a clicking sound. Insufficient fuel supply from the fuel system: This issue is similar to excessive carbon buildup in the intake pipe, as it also prevents the engine from achieving the necessary air-fuel mixture ratio, leading to the vehicle's failure to start.
