What are the functions of a dash cam?

Automobile driving recorders have functions such as identity recognition, recording vehicle driving time, speed, mileage, overtime driving (fatigue driving) alarm and recording. They also include management software, providing a good human-machine interface to achieve vehicle information input, modification, query statistics, and report printing functions. When using a dash cam, secure the recorder to the car's rearview mirror with a clip, place a power supply device in the glove box, and connect it to the central control cigarette lighter. At this point, the dash cam, portable navigation, and radar detector can all be powered by the power supply device. Finally, tuck any excess wiring behind the glove box. Generally, dash cams do not have built-in memory and rely on memory card expansion or mobile digital hard drives. For SD card expansion, capacities vary from 2G, 4G, 8G, 16G, to 32G. For mobile digital hard drives, capacities can be 250G, 500G, 1000G, etc., meeting users' greater video storage needs.

How many kilometers can a new car run on the highway?

For a brand-new car just off the lot, it's best not to drive on the highway during the break-in period. In principle, within the first 2,500 kilometers, the engine speed should not exceed 2,500 rpm. Most new cars during the break-in period are advised not to exceed 100 km/h in speed, keep the engine speed below 3,000 rpm, and avoid aggressive driving, sudden acceleration, or hard braking. Maintain a steady speed: The key during the break-in period is to drive at a steady speed, avoiding rapid acceleration or braking, and high-speed rotations. Once the break-in period is over, it's necessary to take the car for a highway run. Watch for component damage: Pay attention to any unusual noises, as they may indicate installation or configuration issues with certain components. Remember to address these issues for free during the first maintenance service, as some parts may not be covered for free repairs if damaged after this period.

Does Car Wheel Hub Modification Affect Vehicle Inspection?

If not approved by the traffic management department, the modified car wheel hubs will fail the annual inspection. The law prohibits arbitrary changes to tire sizes, as it may affect the vehicle's performance and comfort, and in severe cases, jeopardize driving safety and lead to traffic accidents. Additional information is as follows: 1. Regulations: 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, including replacement of the frame, body, or engine, require the owner to apply for modification registration with the vehicle management office. Installing spoilers, extensive body kits, or modifying exhaust pipes are generally not allowed. 2. Vehicle Inspection: Vehicle inspection refers to the mandatory annual check-up required for all vehicles with official license plates and registration certificates, equivalent to an annual physical examination for the vehicle according to the "Safety Technical Conditions for Motor Vehicle Operation." Vehicle inspections help promptly eliminate potential safety hazards, encourage better vehicle maintenance, and reduce the occurrence of traffic accidents.

What is the correct sequence for engaging P gear and applying the handbrake?

For automatic transmission vehicles, you should first engage the P gear and then apply the handbrake when parking. Alternatively, you can apply the handbrake first and then engage the P gear, but in this case, you must not release the foot brake until the P gear is engaged. Precautions for applying the handbrake: Do not pull the handbrake too tightly, as overstretching the metal cable or keeping it stretched for a long time can accelerate deformation and aging, leading to a loosened handbrake or cable breakage. Avoid applying the handbrake after driving on snowy or icy roads in winter, as accumulated snow may freeze the handbrake, making the vehicle unable to move. Additionally, when washing the car in winter, avoid using the handbrake; instead, use a gear or bricks to secure the vehicle. Do not park on a slope with the handbrake engaged for extended periods. Precautions for gear shifting: Do not look down at the gear lever when shifting gears. Coordinate the clutch properly when shifting gears. Control the speed before shifting gears. Avoid skipping gears when shifting.

How to Distinguish Good and Bad Car Paint Jobs?

Methods to distinguish good and bad car paint jobs are as follows: 1. Check the drying quality of the paint film: Press the painted surface firmly with your finger to see if there are obvious fingerprints. If fingerprints appear, it indicates poor drying of the paint film. The car needs to be re-baked in a paint booth. 2. Check if the color of the paint matches the original paint: Under good lighting conditions, carefully observe the repainted area and the adjacent body of the car for 7-10 seconds. Cross-check by looking directly at it and then at an angle (30-45 degrees) to see if there is any noticeable color difference. Note that dark-colored cars should be compared against the light, while light-colored cars should be compared with the light behind them. 3. Check the fullness of the paint film and the uniformity of the paint texture: Look directly at the fullness of the paint film. If the paint film is too thick, it will appear cloudy and dull; if it is too thin, the surface will lack brightness and appear dark. A well-full paint film will have a glossy, oily appearance.

Why Does Turning the Steering Wheel with the Handbrake On Cause Noise?

Handbrake system is damaged or the handbrake is applied before the vehicle comes to a complete stop. Handbrake Introduction: The parking brake, commonly known as the handbrake, provides resistance to prevent the vehicle from rolling when parked. The parking brake, also referred to as the handbrake or the parking gear in automatic transmissions, locks the drive shaft or rear wheels. The force applied by the parking brake is much weaker than that of the service brake. Handbrake System: The Electronic Parking Brake (EPB) system integrates temporary braking during driving with long-term braking after parking, and it achieves parking braking through electronic control. The electronic handbrake uses electronic control to implement parking braking. Its working principle is the same as that of a mechanical handbrake, both relying on the friction between the brake disc and brake pads to control parking braking. The only difference is that the control method has shifted from the traditional mechanical handbrake lever to an electronic button.
