Does the Dash Cam Continue Recording After the Car is Turned Off?

The dash cam can continue recording after the car is turned off. The parking monitoring function primarily relies on the dash cam automatically starting to record when it detects vibrations. This functionality is achieved through a built-in high-sensitivity gravity sensor. Operating time of the dash cam: If the dash cam is wired to a constant power source during installation, providing 24-hour power supply, and if the parking monitoring, time-lapse recording, or motion detection features are enabled on the dash cam, then after the car is turned off, the dash cam will start recording upon detecting vibrations and automatically save the video without overwriting it. If there is movement within the range of the dash cam's camera, the motion detection feature will activate and automatically start recording. With time-lapse recording enabled, the dash cam can continue recording around the clock even after the vehicle is turned off. Important notes: Even though the dash cam can record after the car is turned off, it's important to be aware that dash cams have blind spots. Single-lens dash cams can only capture the front view, dual-lens dash cams can capture the front and rear, and 360-degree panoramic dash cams can capture all angles. For safety considerations, it is recommended to park the vehicle in an area with surveillance cameras.

What are the reasons for engine coolant deficiency?

Here are the reasons for engine coolant deficiency: 1. When the water temperature rises, the steam inside the water channel forces the coolant out of the reservoir. 2. Poor performance of the water pump or thermostat can cause the circulating system's water temperature to become too high, leading to excessive pressure inside the radiator and cooling system, which results in coolant flowing out from the reservoir. 3. Poor sealing of the cylinder gasket. Below are some related points: 1. Lack of coolant in a car means the car's engine and radiator lack protection. 2. Insufficient coolant in a car can affect the radiator's heat dissipation efficiency, failing to achieve the necessary cooling effect. This disrupts the normal circulation of coolant, leading to high temperatures and, in severe cases, can cause engine damage.

How to Spray Windshield Washer Fluid?

Windshield washer fluid spray switch is located on the right-hand stalk of the steering wheel, which also operates the wipers. Pull the stalk towards yourself to spray the fluid. Windshield washer fluids are mainly divided into three types: summer-use fluid, winter-use antifreeze fluid, and special antifreeze fluid. Summer-use fluid is primarily used to remove insect residues from the windshield. It is important to choose the appropriate windshield washer fluid based on different climates and temperature conditions. Below are the key features of windshield washer fluids: 1. Cleaning Performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby achieving cleaning and stain removal. 2. Antifreeze Performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze effects and quickly dissolving frost. 3. Anti-fog Performance: A single-molecule protective layer forms on the windshield surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with a clear field of vision.

Can a Car with Modified Scissor Doors Pass the Annual Inspection?

Modifying a car with scissor doors requires applying for a change registration at the vehicle management office and obtaining approval before the modification can proceed. If the modification is not approved by the traffic management department in advance, the modified car will not pass the annual inspection normally. According to the relevant provisions of the current "Motor Vehicle Registration Regulations," any changes to the body color, model, performance, purpose, or structure of a licensed motor vehicle, or the replacement of the frame, body, or engine, must be reported to the vehicle management office for a change registration. The national regulations on car modifications stipulate that the following situations will not be eligible for change registration: 1. Vehicles that alter the brand, model, or engine type of the motor vehicle, except for engines that are optionally installed with the permission of the competent department of motor vehicle products under the State Council; 2. Vehicles that change the registered appearance or technical data of the motor vehicle, unless otherwise stipulated by laws, regulations, or national mandatory standards.

What Causes Engine Oil Consumption in Cars?

It may be due to oil burning faults or engine oil leakage faults. Here is extended information: 1. Stuck piston rings prevent oil from returning to the oil pan, causing oil shortage and oil burning phenomenon. 2. The seal valve of the turbocharger prevents oil from returning, resulting in oil burning where the oil doesn't actually participate in combustion. This can cause the car to lose one liter of oil per 1000 kilometers. 3. Improper timing belt replacement operation blocking the crankcase ventilation port, preventing oil from returning. This issue often occurs in vehicles with special design structures, such as Citroen and Peugeot's 1.2T engine. This engine design immerses the timing belt in the oil pan, requiring belt replacement every 40,000-50,000 kilometers. Due to the special design, inexperienced repair shops may improperly block the crankcase ventilation port during belt replacement, causing oil to not return and resulting in the so-called oil burning phenomenon.

What are the penalty standards for stopping midway in Subject 2?

Stopping midway during reverse parking, parallel parking, or right-angle turns results in a 5-point deduction, while stopping during curve driving (S-curve) leads to an immediate failure. Except for designated stopping areas, any pause lasting more than 2 seconds or an abrupt stop is considered stopping midway and will be penalized. For the C1 license test, the required items include reverse parking, parallel parking, hill start and stop, right-angle turns, and curve driving (commonly known as S-curve). Some regions may include a sixth item, such as highway toll card collection. The C2 license test includes reverse parking, parallel parking, right-angle turns, and curve driving (S-curve). For large vehicles (A1, A2, A3, B1, B2), the test items include pole test, hill start and stop, parallel parking, single-plank bridge, curve driving, right-angle turns, narrow gate passage, continuous obstacle course, bumpy road driving, narrow road U-turn, and simulated scenarios such as highways, continuous mountain curves, tunnels, rain/fog conditions, slippery roads, and emergency handling. If you fail during Subject 2, you can continue completing the remaining items before returning to the starting point for a free retake. If the retake is also unsuccessful, the test will be terminated, and you must wait at least 10 days before reapplying. You have a total of 5 attempts for Subject 2. If you fail the 5th attempt, you must restart the driving test from Subject 1. Tips to avoid stopping midway in Subject 2: Increase speed slightly when encountering road transitions or uneven surfaces. When performing maneuvers requiring full steering lock, slightly release the clutch to prevent stalling due to insufficient power. Coordinate clutch and brake use—release the clutch more when moving slowly, avoid heavy braking, and apply throttle if necessary. Stopping outside the test area is not considered stopping midway. If another candidate is ahead in a test area, you may wait outside without penalty.
