In seat heating, the letters HI stand for the English abbreviation of 'high,' meaning high-level heating; LO is the English abbreviation for 'low,' indicating low-level heating. Function of seat heating: The seat heating function uses heating wires inside the seat to warm it, preventing discomfort from excessively low seat temperatures during long winter rides. Symbol for seat heating: The seat heating symbol is a seat icon with three upward-pointing wavy arrows. Heating is generally divided into three levels: low, medium, and high. The button is usually installed on the center console, next to the air conditioning knob, though some models may place it on the left side of the driver's seat or on the driver's door. Reasons why the seat heating light is on but the seat is not heating: If the seat heating light is on but the seat temperature does not rise, it is likely due to damaged heating wires. The seat heating function works similarly to an electric blanket—if the heating wires are damaged, heating cannot occur, and the indicator light will remain on. Additionally, a short circuit in the seat heating switch or a blown fuse can also prevent the seat from heating. Specific issues should be diagnosed and repaired at a 4S shop.

I've been driving for over a decade and the difference between hi and lo seat heating is quite noticeable. Hi is the high-temperature mode with greater power for faster heating. In winter, pressing hi warms your seat within minutes - perfect for freezing weather. Lo is the low-temperature mode with gentler, slower heating ideal for mild autumn/spring days when you don't need intense warmth. My advice: start with hi for quick warming, then switch to lo after five minutes to maintain comfort - this saves energy and prevents overheating. For long drives, lo is better to avoid sweating or burning sensations. Actually, hi reaches over 40°C while lo stays around 30°C - remembering this difference really enhances your driving experience.

The main difference between seat heating 'hi' and 'lo' lies in the heating intensity. 'Hi' stands for high, featuring stronger current, higher temperature, and faster warming-up speed, making it ideal for quickly thawing in cold weather, though it consumes more electricity. 'Lo' stands for low, with weaker current, lower temperature, and slower warming-up speed, consuming less electricity and being more energy-efficient. Personally, I find the 'hi' mode suitable for short trips or extremely cold environments, while 'lo' is more practical for long-distance driving to avoid localized overheating. Generally, the 'hi' temperature setting in cars is around 40 degrees Celsius, while 'lo' is around 30 degrees. Switching between them appropriately can extend the lifespan of the heating wires. Especially in electric vehicles, using 'hi' mode can drain the battery faster, so it's advisable to use 'lo' more often to save power. This simple feature, when used wisely, can be very considerate.

HI means high-temperature rapid heating, which quickly warms up the seat when you get in the car during winter; LO is low-temperature slow heating, gentle and not too hot, suitable for spring and autumn. Here's how I often use it: on cold days, I start with HI to heat the seat, then switch to LO after a few minutes to maintain comfort. HI consumes more power, while LO is more energy-efficient and safer, ideal for long drives. Avoid keeping HI on continuously, as it may cause overheating and discomfort. Proper usage enhances driving pleasure.

How much fuel does it take to run the car air conditioner for an hour?

It consumes about 2~3 liters of fuel per hour. The engine remains idling, so the fuel consumption is not very high. Here are the details: Engine idling: Engine idling consumes a significant amount of fuel. When idling, the engine only powers the air conditioning compressor. If the engine remains in a high-temperature state for a long time, carbon dioxide and carbon monoxide can accumulate inside the car, which is very dangerous. Precautions: Smoking while the car air conditioner is on prevents the smoke from being expelled outside the car promptly, which can harm the eyes and respiratory system. Avoid adjusting the temperature excessively. For quick cooling, setting the car air conditioner to the lowest temperature directly affects the human endocrine system. Prolonged exposure to excessively low temperatures can cause symptoms like lower limb soreness and overall chills. It's best to maintain a temperature difference of 5-6℃ from the outside.

Where is the child lock on the Nissan Tiida?

Nissan Tiida's child lock is located on the rear doors, and the switch button is on the door armrest of the driver's seat. Introduction to child lock: The car child lock, also known as the door lock child safety, is set on the rear door lock of the car. After opening the rear door, there is a small lever (safety mechanism) below the door lock. Move it towards the end with the child icon, then close the door. At this time, the door cannot be opened from the inside, but can only be opened from the outside. Function of child lock: Its function is to prevent active and unaware children from opening the door during driving when children are seated in the rear, thereby avoiding danger. In this case, the door can only be opened by an adult from the outside after parking. If the rear door of the car cannot be opened from the inside but can be opened from the outside, it is very likely that the child lock is in effect. This is because the rear passengers have triggered the safety mechanism when getting on and off the car, and it only needs to be reset.

What are the reasons for Chery Tiggo's difficulty in starting when cold?

Chery Tiggo's difficulty in starting when cold may be due to excessive carbon deposits or low engine temperature. Excessive carbon deposits leading to frequent faults: When there is excessive carbon buildup inside the engine, the gasoline sprayed by the cold-start fuel injector is largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts. This makes starting difficult until the carbon deposits become saturated with gasoline, after which the engine starts more easily. After starting, the gasoline adsorbed on the carbon deposits is then drawn into the combustion chamber by the engine's vacuum suction, making the air-fuel mixture too rich. This fluctuation between lean and rich mixtures causes idle shaking after a cold start. Low engine temperature: When the engine temperature is too low, both the fuel and lubricating oil are not at optimal temperatures. Therefore, more fuel should be injected during cold starts to meet power requirements. Poor fuel atomization at low temperatures leads to reduced ignition energy, affecting performance and causing the car to shake. Aging ignition coils, spark plug high-voltage wires, or electrical leakage can also result in decreased ignition energy.

What is Body Torsional Stiffness?

Stiffness refers to the resistance of a vehicle body to elastic deformation. The stiffness of a vehicle body is certainly an area worth in-depth study, but currently, the domestic level in this field is still relatively weak. Various vehicle models still obtain values through benchmarking and testing to set their respective target values. Design values for static body torsional stiffness: Class A vehicles: The target value for body-in-white torsional stiffness is approximately ≥10,000 N·m/rad. Class B vehicles: The target value for body-in-white torsional stiffness is approximately 10,000 13,000 N·m/rad. Class C vehicles including SUVs: The target value for body-in-white torsional stiffness is approximately ≥13,000 N·m/rad. Class D or higher: The target value for body-in-white torsional stiffness is approximately >13,000 no upper limit N·m/rad (the upper limit depends on the vehicle model's target).

What causes the lack of power in the Komatsu 60-7 large engine unit?

The reasons for the lack of power in the Komatsu 60-7 large engine unit are as follows: Damage to the pressure relief valve's pressure regulating spring: The function of the pressure relief valve is to regulate the higher input pressure to the specified output pressure through the pressure regulating spring and ensure the balance of the output pressure. Once the pressure regulating spring of the pressure relief valve is damaged, the transmission will not be able to maintain normal output pressure. Damage to the transmission pump: The function of the transmission pump is to control the high-pressure oil generated by the torque converter and distribute it to the second shaft assembly through the transmission distribution valve, thereby achieving the forward and reverse movement of the loader. Damage to the transmission pump can cause poor oil supply to the transmission. With prolonged use of the loader, increased wear can lead to internal leakage in the transmission pump, causing the transmission pressure and mechanical efficiency to fall below requirements. This results in poor oil supply in the suction pipeline, preventing the oil from lubricating the moving parts, increasing friction, and causing the system to overheat. It is important to note that air leaks or blockages in the transmission pump's suction pipeline can also lead to insufficient flow, causing the oil temperature to rise too high.
