The red color indicates a very serious problem in the corresponding system. When this occurs, do not continue driving. Pull over safely and seek professional assistance immediately to prevent unpredictable risks to both the vehicle and personal safety. An exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. There are many dashboard warning lights with exclamation marks, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and windshield wiper fault indicator. Below is a detailed explanation of exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor faults, fuel cutoff system intervention or malfunction, external light faults, engine oil pressure sensor faults, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission fault or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circle with parentheses indicates a brake system warning, typically due to a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Abnormal: An exclamation mark with a horizontal line below parentheses is the tire pressure monitoring warning light. It illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a fault in the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or check the commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. In addition, during daily vehicle use, the fault lights displayed on the dashboard are divided into two colors—yellow and red—for different levels of severity: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the nearest repair point to eliminate potential safety hazards. Note: When the car is started, all warning lights will illuminate as the system performs an automatic check. They should turn off after the check is complete. If a light does not illuminate when the ignition is turned on, remains lit, or lights up while driving, it indicates a fault in the corresponding system. In such cases, seek professional help immediately for inspection and to eliminate safety hazards.

How does a car air conditioner cool?

The cooling principle of a car air conditioner is as follows: The refrigerant absorbs heat in the evaporator in a liquid state, and the low-temperature liquid absorbs the latent heat of vaporization to become a gaseous refrigerant, which is then sucked in and compressed by the compressor. The compressed gas increases in both pressure and temperature before flowing into the condenser. Car air conditioners are all air-cooled, and the refrigerant gas is condensed in the condenser. The condensed high-temperature and high-pressure liquid is stored at the bottom of the condenser and in the liquid reservoir. The heat released during condensation is carried away by the fan and dissipated outside the car. When the high-temperature and high-pressure liquid flows through the expansion valve, it returns to a low-temperature and low-pressure liquid state and re-enters the evaporator to absorb the latent heat of vaporization for cooling, thus completing the refrigeration cycle.

Standard Dimensions of Roadside Parking Spaces?

According to the "Specifications for Setting On-Street Parking Spaces on Urban Roads," the standard dimensions of general parking spaces are determined based on vehicle size. Small parking spaces typically measure 2.5~2.7 meters in width and 5~6 meters in length. The width of a single-lane turning lane should be no less than 3.5 meters, while a double-lane turning lane should be no less than 5 meters. The turning area should accommodate a vehicle's one-time turning needs. For safety or to accommodate medium and large vehicles, parking spaces are often set to 6 meters or longer. Details are as follows: (Length ≤ 6m, width ≤ 1.8m): The spacing between vehicles should be no less than 0.5 meters, and the distance between a vehicle and walls or the ends of the parking space should also be no less than 0.5 meters. (6m < length ≤ 8m, 1.8m < width ≤ 2.2m): The spacing between vehicles should be no less than 0.7 meters. Small vehicle parking space: Length ≥ 5 meters, width 2.2–2.5 meters. Large vehicle parking space: Length 7–10 meters, width 4 meters, depending on the vehicle type. Per the "Architectural Design Specifications for Parking Garages," the dimensions for small car parking spaces in indoor garages are as follows: The external design dimensions of small cars are 4.8m (length) × 1.8m (width) × 2.0m (height). For perpendicular parking, the minimum parking space size should be 5.3m (length) × 2.4m (width), with a minimum driveway width of 5.5m at the front. The minimum distance between small cars and side walls should be 0.6m, and the distance to front/rear walls should be 0.5m. Modern underground garages have large floor areas and numerous parking spaces. To ensure smooth vehicle movement, driveways are planned to be relatively wide. Driveways, as horizontal passages dedicated to parking spaces, account for a significant portion of the floor area—often 50% or more of the total parking space area. Parking space arrangements can be categorized into three types: parallel, angled (30°, 45°, 60°), and perpendicular. Large vehicle parking spaces should not use angled or perpendicular arrangements. Details are as follows: Parallel parking space: Standard length 6m, width 2.5m. Angled parking space: Diagonal length 6m, width 2.8m, with a vertical distance of 2.5m between the two angled lines. Perpendicular parking space: Length ≥ 5m (typically 6m), width 2.5m. The optimal standard size is 2.5m × 5.3m. The "Road Traffic Safety Law" stipulates that on-street parking spaces are prohibited on roads with a width of less than 6m, as well as on crosswalks, expressways, and main roads. On urban roads, government authorities may designate parking spaces where pedestrian and vehicle traffic is not impeded. On-street parking spaces should not interfere with non-motorized vehicle passage or encroach on their space. They should not be set near intersections, building entrances, or bus stops. Parking restrictions (e.g., vehicle type, time limits) must be clearly marked with signs. Measures should be taken to avoid obstructing traffic flow. Additionally, on-street parking spaces must not have ground locks to prevent private occupation. Roads where parking is prohibited may feature barriers, bollards, or curbs. When parking spaces are removed, all related markings and signs must be cleared promptly to prevent illegal parking. On-street parking spaces should not be set within 200m–300m of off-street public parking lots. Quantitative rules for on-street parking space setup: The "Specifications for Setting On-Street Parking Spaces on Urban Roads" provide quantitative guidelines based on road width. For two-way roads: if the actual width exceeds 12m, parking spaces may be set on both sides; if between 12m and 8m, parking may be allowed on one side; if less than 8m, no parking spaces are permitted. For one-way roads: if the actual width exceeds 9m, parking may be allowed on both sides; if between 9m and 6m, parking may be allowed on one side; if less than 6m, no parking spaces are permitted. For disabled parking spaces, the specifications require that at least 2% of total parking spaces be designated for disabled use, with a minimum of one space if there are 20 or more parking spots. Parking space marking colors: White: Paid parking spaces. Blue: Free parking spaces. Yellow: Reserved parking spaces. Time-limited parking spaces: Dashed borders (10cm line width) with permitted parking times marked inside (60cm-high numbers). Disabled parking spaces: Special markings with yellow grid lines on both sides indicating no-parking zones for boarding/alighting. Other vehicles must not occupy these spaces. The yellow grid lines should be 120cm wide, with 20cm outer lines and 45° internal angles matching the parking space length. Prohibited areas for on-street parking spaces: Fire lanes, roads with no-parking signs/markings, or construction zones that impede traffic. Roads designated for disaster relief or emergency evacuation. Sidewalks (if set, must not encroach on tactile paving for the visually impaired). Near building entrances. Within 50m of intersections, railroad crossings, sharp curves, narrow roads (<4m), bridges, steep slopes, or tunnels. Within 30m of bus stops, emergency stations, gas stations, fire hydrants, or fire stations (except for authorized vehicles). Within 20m of intersection channelization zones. Within 15m of underground utility (water, electricity, gas) access points. Within 200m of off-street parking lot entrances.
