The biggest difference between tire pressure display and tire pressure warning is that the tire pressure display can visually show the tire pressure, while the tire pressure warning is just an alarm system that alerts when the tire pressure is too high or too low. What to do if the tire pressure is insufficient: If there is no visible damage to the car's tires, you can simply inflate them to the normal tire pressure and then reset the tire pressure system. If a puncture is found upon inspection of the car's tires, you need to drive to a car repair shop promptly to have the tire repaired before reinflating it. If the tire pressure warning appears again some time after inflating, but there is no hole in the tire, it may be due to air leakage caused by a deformed wheel rim. It is recommended to check the wheel rim and replace it if necessary. The working principle of tire pressure monitoring is: It uses pressure sensors installed inside the tires to measure the tire pressure and wireless transmitters to send the pressure information from inside the tire to a central receiver module.

The difference between tire pressure display and tire pressure warning is quite significant. Based on my driving experience, tire pressure display shows the current pressure value of each tire directly on the dashboard, such as seeing specific numbers like 220kpa for the front tires and 210kpa for the rear tires. This allows me to proactively check before driving to ensure all pressures are within the normal range. On the other hand, tire pressure warning is triggered only when the system detects abnormal pressure, such as when the pressure is too low or too high, by lighting up a warning light or sounding an alarm to alert me that there is an issue that needs attention. Essentially, the display provides information to help me prevent problems, acting like a tire maintenance tool, while the warning gives an alarm in emergencies to ensure safety. In practical use, the display function is used more frequently, such as when I check it regularly during city commuting to avoid tire leaks; the warning is more like a safety net, only popping up to alert at critical moments. With over 10 years of driving experience, I've found that these two functions work best together: the display helps extend tire life and save fuel, while the warning buys time to save lives before a tire blowout risk. In short, one is proactive and the other is passive, both enhancing driving peace of mind.

How Long Does the Sylphy Engine Last?

The national policy-guided scrappage standard for the Sylphy engine is 600,000 kilometers. The lifespan of the Nissan Sylphy engine depends on the owner's driving habits, whether routine maintenance is properly performed, and the vehicle's operating environment, all of which significantly impact the engine's longevity. Use high-quality engine oil: Engine oil, also known as engine lubricant, serves functions such as lubrication, cleaning, cooling, sealing, and wear reduction for the engine. Only by using qualified lubricating oil can engine component wear be minimized and service life extended. Therefore, it is essential to use high-quality oil and avoid substandard products or allowing the engine to run without oil. Use qualified coolant (antifreeze): In addition to preventing freezing, antifreeze also prevents the radiator from overheating and scale formation. Thus, antifreeze is crucial to the entire cooling system of the car. Like engine oil, antifreeze should not be mixed with other types. Maintain proper fuel levels: When the fuel warning light comes on, the fuel tank is nearly empty, which can stir up sediment and damage the engine. Additionally, avoid mixing different fuel grades, as this can cause engine knocking and damage.

What are the precautions for running in a new car?

When running in a new car, pay attention to preheating before starting; avoid emergency braking; ensure fuel quality; avoid long-distance trips and perform initial maintenance. The reason for preheating before starting is that when the vehicle is turned off, the engine oil inside will slowly flow back into the oil pan. After starting the vehicle, it takes some time for the oil to fully lubricate all parts of the engine. Avoiding emergency braking means prohibiting sudden braking. When emergency braking occurs in a new car, it will subject the braking system to a huge impact, while also increasing the impact load on the chassis and engine. Ensuring fuel quality requires using high-quality gasoline. The oil used in a new car should not be of a lower grade than specified by the manufacturer, and anti-wear additives should not be used to avoid insufficient running-in despite sufficient mileage. Long-distance trips are prohibited during the running-in period of a new car. Long-distance driving causes the engine to operate continuously for extended periods, which can easily lead to increased wear of mechanical parts. Initial maintenance is required for first-time driving. During the running-in period of a new car, frequently check whether the engine oil, coolant, and battery electrolyte are sufficient, and replenish them immediately if any are found to be lacking.

What does the TC light with a slash mean in the Envision?

The TC light with a slash in the Envision is the Traction Control System indicator. Press the button below the gear shift mechanism, then turn off the ignition and restart to reset the system, and the TC light with a slash will turn off. If the warning light remains on or comes back on while driving, repairs are needed. Possible causes for the TC light to illuminate include: solenoid valve failure; dirty oil clogging the solenoid valve filter; wear on the actuator gear and impeller, causing oil pressure leakage and triggering the alarm; dirty throttle with an opening reaching 20%; or the engine computer misjudging a TC fault. The working principle of the Traction Control System is to replace the mechanical connection between the accelerator pedal and the throttle with an electronic throttle control device. Sensors transmit the accelerator pedal information to the ECU, which generates a control voltage signal based on this information. The motor then adjusts the throttle according to the signal, reducing throttle opening and controlling wheel slip. For drivers operating the vehicle in rainy or snowy conditions, this can help reduce occurrences of wheel slip or loss of control.

Is Idling Harmful to a Car?

If a car is left idling for a short period, it will not cause any damage. However, prolonged idling can lead to carbon buildup in the engine, which is a result of incomplete combustion. Therefore, it is recommended not to leave the car idling for extended periods. When a car idles, incomplete combustion occurs in the engine, leading to carbon deposits. These deposits can cause engine knocking, which is an abnormal combustion phenomenon. During the compression stroke of the engine, the piston moves upward, compressing the air-fuel mixture. This increases the pressure and temperature of the mixture. If the mixture ignites spontaneously at this point, it results in knocking. The burning mixture pushes the piston downward while it is moving upward, affecting the engine's power output and fuel efficiency. Due to the low engine speed and reduced air intake efficiency during idling, combustion is inherently incomplete, making it easier for carbon deposits to form. More importantly, these deposits cannot be expelled and accumulate in the cylinders and intake passages, significantly speeding up the carbon buildup process. When carbon deposits reach a certain level, they can reduce the car's performance and, over time, lead to engine wear. During idling, the car does not perform any external work—the engine only overcomes its own internal resistance. Thus, it is advisable to turn off the engine during prolonged waits.

Does turning on the heater in an electric vehicle consume electricity?

Turning on the heater in an electric vehicle does consume electricity. The heat source for the heater in electric vehicles is typically a PTC (Positive Temperature Coefficient) element in the form of electric heating. The PTC uses a thermistor as the heat source. When electricity is applied, the resistor generates heat, and the blower circulates air over this element to achieve the effect of heating the air. Methods to reduce air conditioning energy consumption: Improve the heat exchange efficiency of the condenser by optimizing the air intake area and cabin backpressure to enhance the airflow field, and use sealing structures to prevent hot air recirculation. Optimize the selection of air conditioning system components and their control strategies. Refine the control strategy of the automatic air conditioning system. In winter, electric vehicles rely on air conditioning and seat heating for warmth, but the principle of the heater differs from that of traditional fuel-powered vehicles. In traditional vehicles, the high temperature of the engine heats the surrounding air, which is then directed into the cabin to provide warm air. However, electric vehicles lack an engine, so their heaters depend on PTC or heat pump systems for heating. These systems are relatively power-intensive and do not heat up quickly. For electric vehicles, seat heating remains the most practical configuration in winter.
