BMW PDC indicates an issue with the parking distance control system. Definition of Parking Distance Control (PDC): PDC is a safety assistance device used during parking or reversing, which alerts the driver about surrounding obstacles through audible signals or more intuitive displays. It eliminates the hassle of checking around the vehicle when parking, reversing, or starting, and helps the driver overcome blind spots and unclear visibility. Components of PDC: PDC mainly consists of ultrasonic sensors, a controller, and a display or buzzer. Ultrasonic Sensors: Their primary function is to send and receive ultrasonic signals, then input these signals to the main unit for display on the display device. Controller: Processes the signals to calculate the distance and orientation between the vehicle body and obstacles. Display or Buzzer: When the sensors detect that the distance between the vehicle and an obstacle reaches a dangerous level, the system alerts the driver through the display and buzzer.

Is Car Window Film Applied on the Inside or Outside?

Car window film is applied on the inside. Here is relevant information about car window film: 1. Functions: Heat insulation and sun protection, UV blocking, safety and explosion-proof, creating private space, reducing air conditioning load, saving fuel, enhancing aesthetics, and preventing glare. 2. Working principle: Through vacuum plating or magnetron sputtering technology, metals such as aluminum, gold, copper, and silver are made into multi-layered, tightly packed high-heat-insulation metal film layers. The higher the metal's conductivity coefficient, the shallower the penetration depth and the higher the reflectivity. These metal layers selectively reflect various heat energy sources in sunlight, including infrared, ultraviolet, and visible light heat energy. Combined with the film's color absorbing solar heat radiation and then releasing it outward again, part of the heat is carried away by outdoor air flow. Thus, it effectively achieves the function of heat insulation.

Why is there no response when starting the BYD F3 with electric ignition?

There may be several reasons why the BYD F3 does not respond when starting: 1. Battery and fuel pressure: Check the battery's charge, fuel pressure, and the fuses in the fuse box. 2. Starter circuit issues: Problems with the starter or its circuit (from the ignition switch to the starter), with a focus on the starter's solenoid switch and the ignition switch. 3. Power supply issues: Observe if the brightness of the dashboard lights changes during startup. If they dim, it indicates a dead battery. If there is no change, it suggests a damaged starter or a faulty ignition switch below the key cylinder. 5. Other issues: Additionally, a dead battery, a damaged starter, or a faulty starter relay can all result in no response when trying to start the engine.

What is the normal indication for the BYD Tang water temperature gauge?

BYD Tang water temperature gauge normally indicates 90°C at the center. Below is relevant information about the water temperature gauge: 1. Principle: Both excessively high or low vehicle water temperature will affect engine operation. Through internal resistance changes, the sensor's resistance variation alters the current flow, driving the water temperature gauge movement to reflect engine operating temperature. 2. Cooling system causing overheating: Insufficient coolant in the cooling system leads to engine overheating. Stop the vehicle, wait for the engine to cool, then add coolant. 3. Heat dissipation causing overheating: Blockage of radiator grille or core ventilation ducts by debris results in poor heat dissipation, causing engine overheating. Replace radiator covers or clean debris. 4. Engine oil causing overheating: Insufficient engine oil or substandard oil quality leads to engine overheating. Simply replace with high-quality engine oil.
