Shift to P first, then turn off the engine. Here are the relevant details: 1. Introduction to N and P gears: These are provided for parking, where N gear is for temporary parking, and P gear is designed for long-term parking. There are considerations when using N gear for automatic transmission parking, as the car may roll if only N gear is engaged. Therefore, N gear should be used for short-term parking and only when the vehicle is completely stationary. 2. Automatic transmission gears: Driving an automatic transmission car only requires using P gear (Park), R gear (Reverse), N gear (Neutral), and D gear (Drive) to meet general driving needs. However, in some special driving conditions, other function gears may be needed.

I remember in my early days of driving, I was always confused about the parking sequence. Later, after learning safe driving practices, I realized the correct method is to shift into P (Park) before turning off the engine. This is because in the P position, the transmission is locked, ensuring the car stays securely parked, especially on slopes where it's less likely to roll. Once, in a hurry, I turned off the engine first, and the car slightly rolled, nearly hitting the curb—it gave me quite a scare. Since then, I've made it a habit to shift into P immediately after stopping, double-checking before shutting off the engine. This not only protects vehicle components but also prevents accidents. Developing good habits greatly enhances daily driving safety. Don't forget to combine it with engaging the parking brake for double security.

I understand the principles of automotive design. When parking an automatic transmission vehicle, you should first shift to P (Park) before turning off the engine. Engaging P activates the transmission's locking mechanism, which secures the output shaft and prevents movement. If you turn off the engine before shifting gears, the transmission remains in an operational state after engine shutdown, potentially subjecting it to unnecessary loads that could damage gears or drivetrain components. Consistently operating this way may increase maintenance costs over time. Good driving habits prolong vehicle lifespan, so it's recommended to follow this procedure every time you park.

Is it normal for a car battery to fail after one and a half years?

It is not normal for a car battery to fail after one and a half years. If you usually neglect maintenance or use it incorrectly, its lifespan will definitely be reduced. Here are the correct methods for using a car battery: Charge frequently: The battery should be used and charged regularly to keep it in a saturated state, which will extend its service life. Do not wait until the battery is depleted before charging it, as this will shorten its lifespan by one-third. Also, avoid overcharging. If the charger is used for a long time, its components will inevitably age, leading to leakage. Prevent overcharging: Overcharging the battery generates a large amount of gas that erodes the plates, accelerating the shedding of active material from the plates and shortening the battery's lifespan. Overcharging also accelerates water loss, leading to the drying up of the electrolyte, an increase in battery temperature, thermal runaway, plate expansion, and casing deformation.

Can You Shift from D to S Gear While Driving an Automatic Transmission Car?

You can shift from D to S gear while driving an automatic transmission car. The functions of D and S gears are basically the same. The D gear is the drive gear of the car. When this gear is engaged and the accelerator is pressed, the car can move forward normally, and the automatic transmission performs gear shifting operations. The S gear, on the other hand, is the sport mode. When this gear is engaged, the automatic transmission downshifts more aggressively, the power response becomes more intense, and driving becomes more exciting. Therefore, when the car is moving forward normally, most automatic transmission models can shift directly from D to S gear. The only difference is that the transmission will perform continuous downshifts. As long as the accelerator pedal is kept pressed, the ECU will generally perform the corresponding fuel compensation automatically. For cars with manual-automatic transmission, it is better to use D gear when driving on the highway because the car usually maintains a speed of 90-120 kilometers per hour on the highway. When traffic is not heavy, operations like overtaking, rapid acceleration, or sudden deceleration are rarely needed. In such cases, using D gear makes driving safer, smoother, and more fuel-efficient. As for the S gear, it is best used when overtaking. Since overtaking on the highway often requires higher speeds, engaging the S gear allows the car to achieve greater output torque, making the overtaking process shorter and safer.

What is the general lifespan of an automobile motor?

Generally around 15 years, but a high-quality, well-maintained engine can last up to 20 years. A major overhaul is typically performed at 150,000 kilometers to extend its service life. For private vehicles that have been in use for 15 years, inspections are required every 6 months (twice a year) until they fail the inspection. Charging time: Generally, the larger the battery capacity, the longer the charging time. For example: A 12V48AH battery indicates a voltage of 12V and a capacity of 48AH. Using an external charger with a 4.8A current, it takes approximately 14 hours to fully charge. Charging method: While the car is running, the alternator replenishes the battery. However, when the battery is severely depleted, immediate recharging is necessary. The car's own charging capacity is insufficient in such cases, and a portable charger must be used. It takes about 20 hours to charge a car's starting battery.

What Causes a Car to Have No Idle Speed?

Spark plugs that have not been maintained for a long time accumulate excessive surface contaminants, often due to not being replaced every 30,000 kilometers. If there is oil or carbon buildup in the car's throttle body, it is necessary to promptly visit a 4S shop or a repair shop to clean the throttle body. Specific Reasons: A blocked intake tract can cause idle speed fluctuations, while carbon deposits or oil in the throttle body are the most common causes of unstable idle speed. Carbon buildup in the throttle body affects its opening degree and the intake air volume, leading to erratic engine RPM fluctuations and strong vibrations when the car is started cold. Precautions: Severe oil or carbon buildup in the throttle body, including a dirty intake tract, can make it difficult to start the car in cold weather. A dirty throttle body requires cleaning, which is considered a routine maintenance task. Spark plugs can also accumulate carbon deposits, and cleaning can restore their activity. However, some spark plugs may experience performance degradation as they near the end of their lifespan. Weak sparks from individual spark plugs can affect the car's performance, and generally, faulty spark plugs may cause the car to exhibit "misfire" symptoms.

Is There Any Issue with a Car Battery Stored for 10 Months?

There is no issue with a car battery stored for 10 months. Generally, the warranty period for car batteries after leaving the factory is 1 year or 20,000 kilometers. Definition of Car Battery: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. A storage battery is an electrochemical device that stores chemical energy and releases electrical energy when needed. Lead-Acid Battery: The commonly referred to car battery is the lead-acid battery. It is primarily made of lead and its oxides, with a sulfuric acid solution as the electrolyte. Some batteries develop high internal resistance after prolonged use, appearing fully charged quickly but discharging rapidly. Such batteries may show normal no-load voltage when tested with a multimeter. Therefore, it's essential not only to measure the no-load voltage but also to test the discharge current, which can be done using a discharge tester.

Does the Car Battery Need Replacement?

Batteries that fail inspection need replacement, while those that pass do not. Generally, a car battery can last at least 3 to 5 years before requiring replacement. Regular Battery Inspection: The vehicle's user manual provides clear maintenance recommendations for the battery. If the car is used frequently, the battery should be inspected every two years; if used infrequently, an annual inspection is sufficient. Batteries that fail inspection need replacement, while those that pass do not. Impact of Usage Habits on Battery Lifespan: If the battery is frequently in a low-charge state or if the vehicle's electrical system is equipped with high-power-consuming devices, the battery's lifespan will be shortened accordingly. The battery's longevity is also influenced by the driver's habits, such as frequently making short trips where the vehicle is driven less than 10 kilometers after starting, which can reduce the battery's service life.
