How to Install Front Car Radar?

The installation method for front car radar: 1. First, mark the installation positions of the four sensors on the front bumper, apply black electrical tape, and then drill holes using the provided drill bit. 2. Remove the plastic cover above the grille, use a wire tool (such as an iron wire) to pull the sensor signal wires into the engine compartment, connect the sensors, and organize the wiring harness. 3. Remove the cover above the accelerator pedal, guide the signal wires of the four sensors from the front of the car into the cabin. Install the radar display near the A-pillar and tuck the wires into the interior seams. 4. Open the glove box cover on the passenger side, locate the ACC fuse interface (can be identified using a test pen), and connect the red wire. 5. Route the red ACC power wire from under the dashboard to the main driver's cabin and connect it to the pink wire of the main unit plug. Connect the black wire to the ground. Locate the brake light wire in the main wiring harness (use a test pen to identify; it lights up when the brake is pressed and turns off when released), and connect it to the white wire of the main unit plug. 6. Plug the connectors of the four sensor signal wires, power wires, and display wires into the main unit, then start the car for debugging. Since the four sensor signal wires are not labeled, each sensor needs to be tested individually to determine the correct order, and the connectors should be reinserted accordingly. 7. After debugging, secure the main unit, restore the interior, and complete the installation.

How to Read an Automotive Air Conditioning Refrigerant Gauge?

Automotive air conditioning refrigerant gauges display pressure readings, which indicate the compressor's discharge pressure (high pressure) and suction pressure (low pressure). These readings help determine whether the system is functioning properly, such as identifying issues like blockages or refrigerant leaks. The gauge typically shows MPa (megapascals) and bar, which are commonly used pressure units in China. 0.1MPa = 1bar = 1 kg/cm². Taking the commonly used R22 refrigerant as an example, under normal operating conditions of the refrigeration system, the low pressure generally ranges between 3-6 bar, and the high pressure between 10-25 bar, depending on the ambient temperature. Precautions for Adding Refrigerant: When adding refrigerant to the air conditioning system, it is crucial to ensure that the piping system has expelled any excess air, moisture, or blockages. After prolonged use, the air conditioning system requires periodic replenishment of Freon. Typically, this task is entrusted to professionals, as they know where to source Freon and the correct method of adding it to the system. If your home air conditioning system has been installed for about five to six years, it is necessary to check the Freon levels. When adding Freon, it is important to add the correct amount. More Freon is not necessarily better; the right amount is crucial. Excessive Freon can impair the system's performance, leading to poor cooling or even a complete lack of cooling.

What Does the Brake Hold System Mean?

The brake hold system refers to the BRAKE-HOLD function, also known as the automatic parking function. During vehicle operation, if this system is activated and the conditions are met, when the vehicle comes to a stop by braking, the system will automatically maintain the braking force to prevent the vehicle from rolling. The braking force is released only when the accelerator pedal is pressed, allowing the vehicle to continue moving. Below is a related introduction: Application Scenarios of the Brake Hold System: Common scenarios include temporary stops, such as at traffic lights or during traffic congestion. The system is simple to use: after entering the vehicle, start the engine, fasten the seatbelt, close the door, and press the BRAKE-HOLD button to activate the brake hold system. The function is enabled when the indicator light turns on. If the indicator light does not illuminate or flashes, it indicates a system malfunction. Function of the Brake Hold System: In some models, the brake hold system is also referred to as the automatic parking brake or automatic hold function, typically paired with an electronic parking brake system. When encountering a red light or needing a brief stop during driving, AUTO-H will automatically apply the brakes to prevent the vehicle from rolling after coming to a complete stop, eliminating the need to manually engage the parking brake. When the light turns green, pressing the accelerator will automatically release the brakes. Similarly, when starting the vehicle, AUTO-H automatically engages the brakes to prevent rolling until sufficient power is generated to move forward, at which point the system releases the brakes, allowing the vehicle to proceed.

What to Do If 6 Points Are Deducted During the Probationary Period of a Driving License?

C1 driving license probation period deduction of 6 points will not affect the probationary driving license. Below is extended information about traffic violations: 1. Definition: Violation (violate-regulations) usually refers to traffic violations, which means motor vehicle drivers, non-motor vehicle drivers, or pedestrians violate road traffic safety laws and traffic management regulations. In addition, violations can also refer to handling matters contrary to conventional rules. 2. Ways to avoid: (1) Be familiar with traffic regulations. (2) Master driving skills proficiently, expand the visible range to avoid distractions, and clearly see traffic police and speed cameras. (3) Try not to speed, and you can also use safety driving systems like navigation devices for speed alerts. (4) Frequently check maps and familiarize yourself with routes to reduce the probability of detours.

What is the Replacement Interval for a Differential?

Generally, the replacement interval for differential oil is every 3 years or 60,000 kilometers, but this may vary depending on the vehicle model. Introduction to the Differential: The automotive differential is a mechanism that allows the left and right (or front and rear) drive wheels to rotate at different speeds. It mainly consists of left and right side gears, two planetary gears, and a gear carrier. Function of the Differential: The role of the differential is to enable the left and right wheels to roll at different speeds when the vehicle is turning or driving on uneven surfaces, ensuring that both drive wheels perform pure rolling motion. The differential is installed to adjust the speed difference between the left and right wheels.

Should Rear Seat Passengers Wear Seat Belts on the Highway?

Yes. According to relevant regulations, rear seat passengers in vehicles must wear seat belts under all circumstances. The seat belt is a safety device designed to protect both passengers and the driver in the event of a severe collision. Failing to wear a seat belt while the vehicle is in motion is considered a violation of the law for all occupants. Not wearing a seat belt in the rear seat not only poses a serious threat to the safety of front-seat occupants but also creates potential hazards for the rear passengers themselves. During deceleration, passengers inside the vehicle accelerate relative to the car, meaning rear passengers experience higher impact forces against the windshield compared to front passengers, significantly increasing their risk of severe injury.
