The rearview mirror heating button on the Teana is the same as the rear windshield defogging button, located on the air conditioning panel, and both can be activated simultaneously. The rearview mirror heating function is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rain or fog from the mirror, eliminating the need for the driver to frequently wipe the mirror manually and thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is required, as there is an adjustment button on the driver's side. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within a few minutes, typically between 35-60 degrees Celsius. The heat is then distributed across the left and right rearview mirrors. As the temperature rises and evaporation occurs, water droplets on the mirror surface gradually shrink, and fog slowly disappears, effectively clearing frost and condensation. However, in heavy rain, the effect may diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves electric heating wires embedded in the mirror, which consume a significant amount of power. When using this function, ensure the car is running. Avoid activating the rearview mirror heating while the vehicle is stationary to prevent draining the car battery, which could leave insufficient power to start the engine. Other methods for defogging rearview mirrors include: Opening windows for air circulation: Crack open the side windows slightly to allow air exchange between the inside and outside of the car, reducing the temperature difference and gradually eliminating fog. Adjusting the car's air conditioning to the appropriate setting can also help defog the mirrors by blowing warm air.

How many kilometers can the Ant 400 actually run?

60km/h constant speed maximum range is 410km. The following is an introduction about the Chery Ant: Range level: The Chery Ant uses a ternary lithium battery provided by CATL, which has many advantages such as high energy density, low life decay, and high charging efficiency. Currently, the Ministry of Industry and Information Technology gives the Chery Ant a pure electric range of 301Km. Although the data on paper does not seem very impressive, it is believed to be more than sufficient for urban commuting. Space performance: The Chery Ant's dimensions are 3200×1670×1550mm, with a wheelbase of 2150mm. It does look very small, but as a three-door, two-seater microcar, this size is actually medium to large within its class. Moreover, it is larger than the Smart Fortwo. Other notes: The Chery Ant eQ1, as the third pure electric microcar under Chery, has been attracting a lot of attention since its launch in 2018.

Why does the gasoline engine water pump lack suction?

Reasons for the gasoline engine water pump lacking suction: 1. Insufficient priming water: Before starting the pump, the pump (including the inlet pipe) should be filled with water. Otherwise, insufficient priming water or air inside the pump will prevent it from drawing water. The solution is to fill enough priming water and exhaust all air from the pump. 2. Inlet pipe leakage: Leakage mainly occurs at the connection between the inlet pipe and the pump body. Check if the rubber gasket is intact, tighten all connecting bolts, and seal the leakage point. 3. Filter head blockage: During installation and use, the filter head often gets clogged by mud, weeds, leaves, or other debris, preventing water flow. Remove the filter head for cleaning. To prevent re-clogging, cover the filter head with a metal mesh to block debris. 4. Shaft (oil) seal leakage: The shaft seal, made of oil-resistant rubber, may wear out over time, causing leakage. Replace the shaft (oil) seal to restore operation. 5. Low voltage: Low voltage reduces water output. Avoid using the pump during peak electricity hours and use larger cross-section wires. Excessive impeller clearance: The impeller clearance is affected by the conical ring. If the clearance is too large, adjust it or replace the conical ring. 6. Installation position too high: If the pump is installed too high, the filter head may be too shallow in the water, easily sucking in air and causing cavitation. It may also exceed the pump's specified lift capacity, resulting in insufficient water output.

What is the difference between pearl white and white?

The difference between pearl white and white car paint: 1. Different colors: Pearl white and white are two types of car paint colors. Pearl white paint contains mica powder inside, which reflects glossy mica particles under sunlight, making it appear very vibrant. In contrast, white car paint does not contain mica powder; the paint is pure white from inside to out and does not emit dazzling colors under sunlight. 2. Different processes: Pearl white is a type of metallic paint, while white car paint is ordinary paint without metallic luster. From a long-term usage perspective, ordinary white car paint tends to turn yellow over time, whereas pearl white paint may show color differences when touched up due to its unique properties. 3. Different prices: Because pearl white contains mica paint, it looks more attractive and is slightly more expensive to repair. Pure white car paint is not as expensive and does not incur such high costs during repairs.

Will the Car Stall if You Only Press the Brake?

Only pressing the brake without engaging the clutch will cause the car to stall because the clutch is not fully disengaged. If the brake is pressed hard, the clutch won't be engaged. At this point, the power transmission is blocked by the locked wheels, and the car will stall due to the reaction force. Typically, when decelerating a manual transmission car, you should first press the brake, then engage the clutch, and begin slowing down. Only by pressing the clutch can the engine be separated from the transmission, ensuring the car doesn't stall when it comes to a stop. Reasons for Vehicle Stalling: Automatic transmission stalling is mainly caused by using low-quality fuel. You can refuel with high-quality fuel at reputable gas stations, such as using 97-octane gasoline. Although it is more expensive, it ensures longer vehicle lifespan and better driving performance. Thoroughly clean the fuel system, including the fuel injectors, throttle body, and fuel tank. The issue may be due to poor fuel quality, excessive gum deposits, or clogged fuel lines, leading to inadequate fuel flow. The main reason for stalling during idle is excessive dust in the air. When the engine is running, a large amount of dirt accumulates on the idle control valve and throttle body. Excessive dirt buildup can cause low idle speed, unstable idle, or stalling while driving. To fix this, simply clean the idle control valve. Fuel line obstruction is also a common cause of stalling while driving.

What does the low beam symbol look like?

The low beam symbol is green. Here is more information about low beams: 1. Introduction: Low beams are designed for close-range illumination, with design requirements including a wide irradiation range (160°), short irradiation distance, and non-adjustable focus. 2. The following situations require the use of low beams: (1) Driving in areas without streetlights at night, or during dusk when it's getting dark or dawn when light is just appearing, low beams must be turned on. (2) In conditions of heavy fog, snow, or heavy rain where visibility is obstructed, low beams must be used even during the day. (3) In some areas where there is lighting but the brightness is insufficient, low beams should also be turned on.

What Causes the Clutch Pedal Not to Return to Position?

The reasons for the clutch pedal not returning to position are: 1. Air in the hydraulic system, causing excessive clutch travel and poor return; 2. Aging clutch spring, which occurs when the vehicle has been used for a long time; 3. Contaminated clutch fluid, leading to clogged oil passages and resulting in the pedal not returning. The clutch pedal is the control device for the manual transmission clutch assembly and serves as the human-machine interface between the car and the driver. It is one of the five major controls in driving, whether during learning or normal operation, and is used very frequently. For convenience, it is commonly referred to as the 'clutch.' Proper operation of the clutch directly affects the vehicle's starting, gear shifting, and reversing.
