The method to start a car with one-key start is as follows: 1. Press the start button once, at which point the ACC light will turn on, then press it again for the vehicle to perform a self-check; 2. Depress the brake pedal and press the start button to ignite the engine; 3. Release the foot brake and choose to warm up the car in place; 4. Depress the foot brake again, shift to D gear, and release the handbrake; 5. Slowly release the foot brake, add a little throttle, and the process is complete. The one-key start device is part of a smart car, serving as a button to simplify the ignition process, and it can also be used to turn off the engine. This device can be retrofitted at the original car key lock position or installed as an independent panel. Cars equipped with the one-key start function generally do not require inserting a key, but they all have a key insertion slot, which is used to start the car with a key in case the one-key start function malfunctions.

I've been driving cars with push-button start for many years, and it's indeed very convenient. There are key steps to remember when starting: sit in the driver's seat, close and lock the door, and most importantly, firmly press the brake pedal. Once steady, press the start button. The button usually glows near the center console, and pressing it starts the engine. If nothing happens after pressing, don't panic—first check if the key is inside the car or near the door. Sometimes the key is too far for the signal to reach, or the battery might be dead and need replacement. Once in winter, it took ten seconds to start because the car was too cold, so I've made it a habit to let the engine warm up for a few seconds before driving to extend the lifespan of the parts. Push-button start saves the effort of turning a key, but minor issues can arise, like slower sensor response on rainy days. Overall, once you get used to it, the driving experience is quite smooth.

What does the N gear in an automatic car mean?

Automatic car N gear is the neutral gear. Generally, when briefly stopping, you can shift into neutral, at which point your right foot can leave the brake pedal to rest. However, on slopes, you still need to press the brake to prevent the car from rolling, unless you engage the handbrake or electronic brake. The common gears of an automatic car are introduced as follows: 1. P gear, the parking gear, which uses a mechanical device inside the transmission to lock the rotating parts of the car. It must only be used when the vehicle is completely stopped. Additionally, when turning off the car, the gear must be in P. 2. D gear, the drive gear. When shifting into D, the driver only needs to control the accelerator pedal to adjust the speed. The transmission will automatically determine the gear based on the accelerator position and vehicle speed, eliminating the need for manual shifting. 3. R gear, the reverse gear. As the name suggests, this gear is used when reversing. It's important to note that you should not force the R gear when the vehicle is not completely stopped, as it can cause transmission wear. 4. S gear, the sport mode. In this mode, the car has greater power, and the engine maintains high-speed operation. You can use this gear when pursuing speed, but it will also increase fuel consumption.

What to Do When a Vehicle Falls into Water?

Here are the steps to handle a vehicle falling into water: 1. Open the windows immediately: As soon as the car falls into water, open the windows to prevent the doors from becoming impossible to open once the car sinks. Allowing water to flow into the car quickly ensures that the pressure on both sides of the door equalizes, making it possible to open the door. If the windows cannot be opened, use an object to break the window, such as the car headrest. The correct method is not to smash but to pry—aim for the window gap, insert, and pry the glass apart. Besides the headrest, tools like a safety hammer or fire extinguisher can be used to break the window, preferably targeting the edges or corners for easier breakage. 2. Open the door promptly: Do not wait until the water reaches the lower edge of the window before attempting to open the door, as the water pressure inside the car will be at its highest, making it very difficult to open. When opening the door, pull the inner handle and use your foot to push at an appropriate angle, which is more effective than the usual door-opening action. 3. If all four doors and windows fail to open as the car submerges, consider escaping through the sunroof. 4. Trunk escape: If the sunroof escape fails, opt for the trunk. Generally, when a car sinks, the front tilts downward while the rear floats upward before gradually sinking. At this point, unfasten the seatbelt, quickly crawl to the rear with the key, fold down the rear seats, locate the trunk release latch, and escape through the trunk. 5. Typically, a car will fill with water within 1-2 minutes. Stay calm during this time. Once the car is fully submerged, push the door open forcefully, swim to the surface as quickly as possible, or climb onto the roof to await rescue. Additionally, those in the water can grab floating objects like basins or fuel tanks, submerging the openings underwater or blocking them to use as flotation devices, thereby extending survival time.

What Causes Insufficient Transmission Pressure?

Here are the reasons for insufficient transmission pressure: 1. Insufficient hydraulic fluid in the transmission or the hydraulic fluid does not meet the specified standards. Generally, such transmissions must use the specified hydraulic fluid, such as No. 8 hydraulic transmission fluid or the manufacturer's designated hydraulic fluid. Ordinary hydraulic fluid is not allowed as a substitute. 2. The oil filter in the oil pan is clogged, resulting in insufficient hydraulic fluid flow. This filter is usually a metal mesh-type filter, and the most common issue is that the oil filter is not replaced for a long time, causing its surface to be clogged with various impurities, gum, metal debris, etc. 3. The oil pipe from the oil pan to the transmission pump is leaking air or has internal damage or delamination. Air leakage can cause the transmission pump to draw insufficient oil or fail to draw oil at all, while delamination can narrow the hydraulic fluid passage, both leading to insufficient hydraulic system pressure. 4. The transmission pump is damaged or excessively worn, resulting in insufficient pressure. Alternatively, the transmission pump drive mechanism (shaft gear) is damaged, preventing the transmission pump from rotating. The most common issue is excessive wear of the internal splines of the shaft gear, which prevents it from driving the transmission pump.

What to Do When a New Energy Vehicle Gets Flooded

When a new energy vehicle is flooded, the first step is to clean the dirt inside and outside the vehicle. Cleaning the exterior is straightforward, but the interior requires professional assistance. Then, park the car in the sunlight, open the windows for ventilation, and dry it out. Use the onboard computer for self-diagnosis to check if all vehicle equipment is functioning properly. For the flooded chassis, a thorough inspection is necessary, and rust-proof spray should be applied if needed. There are three main reasons why electric vehicles may encounter issues when flooded: 1. Issues with the sealing of the motor and battery: If the battery sealing meets relevant standards, there is no need to worry about flooding. Modern electric vehicles typically use permanent magnet synchronous motors, which have undergone water immersion tests and can operate underwater as long as the motor sealing remains intact. 2. Damaged wiring harnesses: Problems with wiring harnesses in electric vehicles are not difficult to resolve. Ensuring proper sealing of the motor and battery means the vehicle can theoretically continue driving as long as the driver has oxygen supply. 3. Insufficient waterproofing standards: The battery pack of an electric vehicle consists of battery cells enclosed in a metal casing. The waterproof standard for the battery pack casing is IPX7, meaning it can be submerged underwater for over half an hour without water ingress.

How Many Hours of Driving Constitutes Fatigue Driving?

According to Article 62 of the "Regulations for the Implementation of the Road Traffic Safety Law," continuous driving of a motor vehicle for more than 4 hours without stopping for a break or with a break time of less than 20 minutes is considered fatigue driving. Fatigue driving is identified when the driving duration exceeds 4 hours or the rest time is less than 20 minutes. The following are situations where fatigue driving is prone to occur: 1. Driving in summer is more likely to lead to fatigue driving. Firstly, the high temperature inside the vehicle and poor air circulation can easily cause the driver to become fatigued. Mental fatigue leads to slower thinking, and drowsiness is especially common in the afternoon. Continuing to drive under these conditions can easily result in accidents. 2. High-speed driving is prone to fatigue driving. When driving at high speeds, the driver needs to be fully concentrated, with the mind constantly in a state of high tension. Prolonged driving increases fatigue, and even a slight lapse in attention can lead to an accident.

Under what circumstances should high beams be turned on?

Here are the situations where high beams should be used: 1. When approaching an oncoming vehicle, you may switch to high beams; 2. When overtaking, turn on the turn signal and use the high-low beam switch to alert the vehicle ahead; 3. When passing through an intersection, use the high-low beam switch to alert vehicles on both sides of the intersection to pay attention; 4. When there are no other lighting facilities on the road and no oncoming vehicles, high beams can be used. Below is additional information: Generally, it is best not to use high beams when driving in the city because lighting conditions are usually good. The high angle of high beams can easily dazzle oncoming drivers and pedestrians, affecting their vision, which is unsafe and considered impolite driving behavior.
