What are the reasons for the radar not making sound in the Hongqi H5?

The reasons for the radar not making sound in the Hongqi H5 are: 1. The power cable of the main unit is not properly connected, resulting in no current; 2. The radar main unit cable has become loose; 3. The radar buzzer is damaged; 4. The wiring at the bumper is damaged. The working principle of the radar is that during reversing, it uses ultrasonic waves emitted by a probe installed on the rear bumper to hit obstacles and reflect infrasound waves, calculating the actual distance between the vehicle body and the obstacle. The functions of the radar are: 1. Accurately measuring the distance between the rear of the vehicle and the obstacle; 2. Emitting an urgent warning sound when reversing to the limit distance to remind the driver to pay attention to braking; 3. Repeatedly emitting a voice warning sound to alert pedestrians.

The issue of no sound from the Hongqi H5 radar is quite common, and there are several possible causes. First, check the radar sensor, which is installed at the rear of the car and can easily be covered by mud or snow, blocking the sensing area and causing the sound to disappear. Cleaning it should solve the problem. It could also be an issue with the sound system, such as the volume being turned down or even muted. Look for the parking radar option in the car’s settings and adjust it back. Loose wiring is another common issue—aging plugs or unstable connections can affect the sound. Try gently wiggling the plug to see if that helps. There’s also the possibility of a blown fuse; check the relevant fuse in the engine compartment’s fuse box and replace it if necessary. From a safety perspective, the radar sound is crucial for parking assistance. Without it, reversing can easily lead to scrapes, so don’t delay fixing it. Regularly cleaning the sensor can prevent issues. Taking it to a 4S shop for repair is faster, as they can quickly diagnose the problem with specialized tools. I recommend starting with simple checks first—it’s cost-effective and efficient.

What are the reasons why a Roewe car won't start?

Roewe car won't start due to incorrect gear position, dead battery, spark plug carbon buildup or malfunction, or lack of fuel. Below are detailed explanations and solutions for the reasons why a car won't start: For automatic transmission vehicles, the gear must be in P (Park) or N (Neutral) position when starting. If placed in R (Reverse) or D (Drive), the car won't start. Some manual transmission vehicles also won't start if the clutch isn't depressed. A dead battery caused by leaving headlights on for extended periods or an expired battery lifespan, as well as aftermarket installations like xenon headlights or high-power audio systems that may cause circuit failures. It's generally recommended to replace the battery every 2 years. First check the car's spark plugs, which are crucial components in the ignition system. The vehicle's ignition system is key to whether the engine runs properly, so spark plug condition directly affects vehicle performance and efficiency. You can unscrew the spark plugs to dry them, then reinstall to start the car. If conditions permit, visit a 4S shop to inspect the ignition system and eliminate causes of low ignition energy, such as spark plug electrode gap, ignition coil energy, or high-voltage line condition. Refueling will allow the car to start.

What Causes the Reversing Radar to Have No Image?

The reasons for the reversing camera displaying a black screen include poor line contact and aging of the video power cable. Among these, poor line contact is the most common cause. It is necessary to promptly check the wiring and the connection points installed on the vehicle to see if there is any loose connection. Simply reconnecting the loose parts properly should resolve the issue. Aging of the video power cable is also one of the reasons for the reversing camera displaying a black screen. You can try replacing it with a new power cable. If the problem is resolved, it confirms that the video power cable was indeed the issue. If the reversing camera still does not display after checking the above two scenarios, it may be due to prolonged use of the reversing camera, resulting in poor chip photosensitivity. This not only causes a snowy screen effect but can also lead to a black screen in severe cases. However, such chip abnormalities require inspection, repair, or direct replacement at a repair shop. The reversing camera uses a far-infrared wide-angle camera device installed at the rear of the vehicle. Through the display screen inside the car, obstacles behind the vehicle can be clearly seen. When the reverse gear is engaged, the system automatically activates the high-definition reversing camera at the rear, clearly displaying the situation behind the vehicle on the reversing LCD screen, allowing the driver to accurately assess the rear road conditions.

Is there a time limit for the reverse parking item in Subject 2 of the driving test?

In Subject 2 of the driving test, the reverse parking item has a time limit, with a completion time of 210 seconds. Generally, if you take the test at the speed of half-clutch engagement, you can complete it in about 170 seconds. Although slowing down can make alignment more precise, you should not be too slow throughout the test, as it may easily lead to exceeding the time limit. When initially entering the test area to adjust the distance between the parking space and the side line to 30-50 cm, you can adjust at the speed of half-clutch engagement. When approaching the stop line and preparing to reverse into the parking space, gently press the clutch to slow down for alignment. After alignment, slightly lift the clutch because once the steering wheel is turned, the vehicle will move at the predetermined angle, so speed does not matter much. The key is to press the clutch when preparing to turn the steering wheel or align, ensuring early deceleration. Simply slowing down during alignment will help avoid exceeding the time limit. Reverse parking is divided into left-side and right-side parking. There are stop lines on both sides of the parking space. The 210-second countdown starts when the vehicle enters the test area and the front wheel crosses the left parking space stop line. After entering the test area, a voice announcement will say "Start reverse parking," and the candidate must complete the parking process within 210 seconds. The timing ends only when the rear wheel crosses the right parking space stop line.

What Causes a Vehicle Status Lock That Prevents Annual Inspection?

Vehicle status lock preventing annual inspection is due to reasons such as court seizure, unresolved accidents, failure to undergo annual inspection on time leading to a lock, or change of residence causing the vehicle's contact information to be inconsistent with actual records, resulting in undelivered correspondence and information from traffic police departments, which leads to the vehicle's services being locked. Methods to Unlock Vehicle Status: If the lock is due to a change of residence, promptly visit the vehicle management office's license processing hall to update contact information and lift the service lock. If the lock is due to court seizure or unresolved accidents, obtain a certificate from the court or the unit that requested the lock from the vehicle management office, resolve the accident, and submit the processed information to the vehicle management office to unlock. Annual Inspection Process After Vehicle Unlock: Bring your ID card, vehicle registration certificate, and a copy of compulsory traffic insurance to the inspection station. Fill out the vehicle license application form and vehicle inspection record form. Check and handle any traffic violations at the violation query window. Undergo vehicle appearance inspection and photograph the chassis number. Submit all documents to the inspection login window for login. Pay the fee at the hall with the login receipt, then hand over the vehicle to staff for emissions, chassis, brake, and lighting tests. After passing the tests, collect the inspection report and submit annual inspection materials, including the registration certificate and insurance policy, for review. Upon approval, receive the annual inspection sticker.

What is the reason for always reversing crookedly when backing up?

The fuel tank capacity of the Zotye T600 is 60 liters, which is the officially announced data. The fuel grade of the Zotye T600 is 92, with a fuel consumption of 7.9-8.6L per 100 kilometers. A full tank of fuel can cover a distance of 697-759km. During daily driving, it is necessary to pay attention to the remaining fuel in the tank at all times. Generally, the fuel level is observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge on the dashboard usually has 5 to 6 segments. When there are only 2 segments left on the fuel gauge, it is time to refuel to avoid running out of fuel halfway. During the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the car manufacturer is the volume from the bottom of the tank to the safe limit. There is still some space from the safe limit to the tank opening, which is reserved to ensure that the fuel in the tank can expand when the temperature rises without overflowing the tank's safety space. If the fuel is filled up to the tank opening during refueling, the actual amount of fuel added will be greater than the calibrated fuel tank capacity.

Subject 2 sitting posture standard: The head should be at least one fist away from the car roof, the knees can be slightly bent, and the hips can touch the seat cushion and backrest. Head position: The driver's line of sight should not be blocked by the steering wheel, allowing clear observation of the dashboard. The head should be at least one fist away from the car roof. Leg position: Place each foot on the clutch pedal and brake pedal respectively, with the knees slightly bent. When the pedals are fully depressed, there should still be some bend in the legs. Hip position: Push the hips as far back as possible until they touch the seat cushion and backrest, ensuring a more stable sitting position. If the seat lacks lumbar support, a cushion can be placed at the lower back.
