Why do manual transmissions require constant gear shifting?

How to Correctly Read Traffic Signals?

Traffic signals consist of three colors: red, green, and yellow. Red indicates no passage, green indicates passage is allowed, and yellow serves as a warning. Traffic signals are categorized into: motor vehicle signals, non-motor vehicle signals, pedestrian crossing signals, directional indicator signals (arrow signals), lane signals, flashing warning signals, and railway crossing signals. At intersections, you can see three-color traffic signals hanging on all four sides, functioning as a silent "traffic police". Traffic lights are internationally standardized signals. The red light is a stop signal, while the green light is a go signal. At intersections, vehicles from several directions converge here, some going straight and others turning. Determining who proceeds first is governed by the traffic lights. When the red light is on, vehicles are not allowed to go straight or turn left, but right turns are permitted if they do not interfere with others or vehicles. When the green light is on, vehicles are allowed to go straight or turn. When the yellow light is on, vehicles that have already passed the stop line or pedestrian crossing may continue. A flashing yellow light warns vehicles to pay attention to safety.

What Are the Reasons for an Automatic Transmission Car Not Starting?

There are several reasons why an automatic transmission car may not start: faulty spark plugs. In extremely cold winter conditions, failure to add engine coolant in time. Incorrect gear selection, preventing startup. A dead battery due to leaving headlights on for an extended period. A dirty throttle body leading to excessive carbon buildup. Faulty spark plugs: If the engine cranks slowly during startup, it may indicate insufficient battery voltage or a damaged starter motor. Inspection and repair are necessary. Lack of antifreeze: Some car owners use water or low-quality antifreeze, resulting in the entire cooling system freezing, engine block cracking, water pump failure, and the car not starting. The correct antifreeze should be used. Incorrect gear selection: When starting an automatic transmission car, the gear must be in P (Park) or N (Neutral). If it is in R (Reverse) or D (Drive), the car will not start. Dead battery: A drained battery due to leaving headlights on for too long or an expired battery lifespan can prevent startup. Additionally, installing aftermarket components like xenon headlights, high-power audio systems, or DVD players can cause electrical circuit issues. The battery should be charged promptly. Dirty throttle body: During a cold start, excessive carbon buildup can block the throttle body, preventing sufficient air intake for engine ignition. Pressing the accelerator slightly to increase throttle opening can help start the engine, followed by cleaning the throttle body.

How Long Does It Take to Charge a Dead Car Battery by Driving?

It takes about 12 hours of driving to fully charge a dead car battery. Below are the maintenance and usage precautions for car batteries: Battery Maintenance Methods: If the car is parked for an extended period, it is recommended to disconnect the negative terminal of the battery to avoid power loss. It is best to start the car once a week to allow the battery to charge via the internal alternator while the engine is idling. Regularly clean the battery to remove surface dust, oil stains, and white acid corrosion residue, which can help extend the battery's lifespan. Battery Usage Precautions: Frequently using in-car electrical devices such as the radio or dome light after turning off the engine can harm the battery and shorten its lifespan. Using electrical devices when the engine is not running continuously drains the battery, which can lead to power loss and affect the car's ability to start. Therefore, minimize the use of high-power electronic devices when the engine is off to prevent excessive battery drain.

How to Use the Handbrake?

Generally, when waiting for a traffic signal on a flat road, pulling the handbrake 2-3 notches is sufficient. Avoid pulling the handbrake too high, as this can make it difficult to release. Gently and smoothly pull up the handbrake, and you should clearly hear the sound of each notch engaging. When pulling the handbrake, the button on the handbrake head will move back and forth, as there is a spring inside applying force. This mechanism is designed to prolong the lifespan of the spring and the small notches. Release the handbrake after starting the car. If you forget to release the handbrake and only realize it after driving for a while, this will significantly increase wear on the handbrake.

Can vehicles undergo annual inspection on Saturdays and Sundays?

Vehicles can undergo annual inspection on Saturdays and Sundays. According to Article 15 of the "Opinions on Strengthening and Improving Motor Vehicle Inspection Work": inspection institutions should implement an uninterrupted system on Saturdays, Sundays, and holidays, providing extended inspection services. However, it should be noted that the annual inspection sticker can only be obtained during working days. Although the inspection companies do not take breaks, the vehicle management offices are closed, and the inspection qualification information needs to be verified on working days before the annual inspection sticker can be issued. Documents required for annual inspection: For individual vehicle annual inspection: original vehicle license, duplicate of compulsory traffic insurance, copy of ID card, and the vehicle. For company vehicle annual inspection: original vehicle license, duplicate of compulsory traffic insurance, copy of the agent's ID card, and the vehicle. Relevant regulations for vehicle annual inspection: Vehicles that fail the annual inspection should be repaired within a specified time limit. If they still fail after the deadline, the vehicle management office should confiscate their license plates and prohibit them from continuing to operate. Vehicles that do not participate in the annual inspection without reason or fail the inspection are not allowed to drive on the road or transfer ownership. Vehicles that meet the scrapping conditions or have exceeded the prescribed service life will not be inspected, and their license plates will be revoked, their files canceled, and they will be scrapped.
