Ground clearance: 50~70cm; Horizontal spacing: The distance between point A and point B, point C and point D should be 30cm. Ensure the arrow direction is facing upwards, then install the ultrasonic sensor. Apply even pressure around the edges of the ultrasonic sensor to press it in, ensuring it fits tightly into the mounting hole. Connect the waterproof and dustproof plug, and tighten it firmly. Determine the wiring length and cut it according to the actual requirements of the vehicle model.

Installing ultrasonic sensors is quite straightforward, I think. First, locate the position - the rear bumper usually has pre-drilled holes or you can drill your own, ensuring even spacing for accurate detection. Measure the spacing carefully, mark it with tape, and drill slowly with a small bit to avoid damaging the paint. Secure the sensors firmly in place to prevent wobbling that could affect readings. Next, wiring: each sensor has a power wire and a ground wire, connect them to the control box, typically matching colors (red for positive, black for negative). After installation, test by engaging reverse gear to check if the obstacle distance alerts are responsive. If issues arise, inspect the contacts or recalibrate - some systems may require manual zeroing. Beginners are advised to have a helper and wear protective gear when drilling to shield the eyes. Don’t rush the process; it should take about half an hour to complete. Once installed, parking becomes more convenient and safer, but remember to check regularly to prevent moisture corrosion at the connectors.

Installing ultrasonic sensors requires attention to detail. First, positioning must be accurate; misalignment can cause false distance readings. Start drilling from the smallest hole and gradually expand to prevent bumper deformation from excessive force. Safety is critical during wiring: disconnect the vehicle battery before operation, ensure the power positive and ground wires are not reversed, and securely connect the control unit interface to its slot. Test by engaging reverse gear and moving slowly to confirm timely and accurate alerts—common issues include loose sensors or insecure wiring. Don’t overlook environmental factors; rain, snow, and ice can affect precision, so install on clear days with moderate temperatures. If alarm sounds are abnormal, potential causes include interference sources or improper calibration—recheck positioning. Maintain a calm mindset throughout the process and prepare tools like pliers and a multimeter for power testing.

Do the taillights illuminate when the handbrake is engaged?

When the handbrake is engaged, the taillights do not illuminate. Only the brake indicator light on the dashboard lights up. When the foot brake is pressed, the brake lights will illuminate. Installation position of car taillights: Taillights alert vehicles behind of the presence of a car ahead during nighttime driving and indicate the positional relationship between the two vehicles, hence they are installed on both sides at the rear of the car. Design principles of car taillights: They must have sufficient luminous intensity so that the taillights can be clearly distinguished by drivers of other vehicles or pedestrians even in bright daylight. During nighttime driving, the light emitted by the taillights should not cause glare or discomfort to drivers of other vehicles or pedestrians.

What Causes Low Idle Speed in Sedans?

Here are the reasons for low idle speed in cars: 1. Oil accumulation and carbon buildup in the throttle body, dirty intake passages: As the vehicle ages, the intake passages can become clogged, and carbon deposits or oil may accumulate in the throttle body, leading to unstable idle speed or even low idle speed. Carbon buildup in the throttle body affects the air intake, causing low idle speed during cold starts. It is recommended that owners clean the throttle body and intake passages to prevent abnormal idle conditions. 2. Weak spark due to faulty spark plugs: Over time, spark plugs can also develop carbon deposits. When the buildup is severe, weak sparks from individual spark plugs can affect the vehicle's performance, resulting in low idle speed. Timely cleaning or replacement of spark plugs is advised. 3. Fuel system blockages, such as clogged fuel injectors, and intake manifold issues: When the fuel injectors are clogged, the fuel supply pressure is affected, leading to poor fuel atomization, which can cause unstable or low idle speed. If the intake manifold malfunctions, the air-fuel mixture ratio becomes unbalanced, potentially causing excessive emissions and failure in vehicle inspections. 4. Malfunctioning sensors: When the car's sensors fail, the correct air-fuel ratio cannot be maintained. Common issues include faulty coolant temperature sensors, oxygen sensors, or throttle position sensors, leading to high fuel consumption and low idle speed.

How to Use Xingrui Key Remote Start?

Xingrui key remote start can be used within 50 meters when the car is locked. First, press the lock button, then hold the start button (long press the circular button) within two seconds to start the engine. This function utilizes the car's remote key to start the engine remotely. The working principle of Geely Xingrui's remote start is as follows: the vehicle starts the engine based on the signal received from the remote key. The entire process eliminates the inconvenience of manually entering the car to operate it. While the engine is running, the central locking system remains locked, providing effective security. Typically, after the engine is started remotely, the vehicle will operate continuously for ten minutes. If no further instructions are received, it will automatically shut off. Features of engine remote start: High reliability. Since the engine remote start is structurally identical to manual start inside the car, both utilize an electric motor to start the engine, eliminating mechanical wear issues with heaters and significantly reducing the likelihood of malfunctions; User-friendly. Although engine remote start cannot be scheduled like parking heaters, the remote start method is equally convenient. The remote range is usually no less than 50 meters, allowing direct remote start from home or office if the car is parked in a ground parking lot; Automatic timing. Typically, if no operation is performed after a certain period, the remotely started engine will automatically shut off, preventing potential fuel waste due to forgetfulness; Whole-car heating. This function, like parking heaters, can warm up the coolant in the radiator, effectively heating the cabin, engine, and windows.

What is the reason why the Honda CR-V's auto start-stop does not engage?

Honda CR-V's auto start-stop does not trigger every time you brake because there are certain conditions that must be met for it to engage. The specific details are as follows: 1. Activating Auto Start-Stop: When the vehicle comes to a stable stop and the tachometer generally drops below 1000 RPM, pressing the brake pedal firmly will engage the auto start-stop system, and the corresponding indicator on the dashboard will light up. 2. Some vehicles require continuous brake pedal pressure: After the auto start-stop system engages, some vehicles require the driver to keep the brake pedal pressed, keeping the foot in a tense state. Releasing the pedal will restart the engine, while in other vehicles, releasing the brake pedal does not affect the system. 3. Auto start-stop does not engage when the air conditioning is on: When the air conditioning is on, the auto start-stop system rarely engages, especially since the engine needs to run to supply air into the cabin. Generally, the auto start-stop will not trigger in this situation. 4. Engine shutdown parking is possible: After the auto start-stop system engages, shifting into P (Park) and opening the driver's door will allow the engine to shut down completely for parking. 5. The system can be manually turned off: If you prefer not to use the auto start-stop system, you can press a button to deactivate it each time you start the car. When parking, you can keep the brake pedal pressed, as the operation remains the same as when the system is active. Alternatively, you can use the electronic parking brake when stopping, release the foot brake to relax your foot, and press the button again to release the electronic parking brake when ready to drive, or simply press the accelerator to automatically disengage the electronic parking brake.

How much should the steering wheel generally turn?

Turning the steering wheel generally requires a 90-degree rotation. Correct hand position for steering: A full turn of the steering wheel is 360 degrees, and a quarter turn is 90 degrees. You can think of the steering wheel as a clock. The correct hand position is to place the left hand near the 9 o'clock position and the right hand near the 3 o'clock position. To turn 90 degrees, rotate the wheel a full turn and then an additional quarter turn. Steering techniques: Beginners practicing steering don't need to worry about the exact degrees of rotation. Just follow the principle of 'turn as much as you need to return, turn less for less return, turn slowly for slow return, turn more for more return, and turn quickly for quick return.' As for how much to turn, you can judge by the steering wheel markings or simply adjust based on the direction of the car's front and body.

Can a Car That Has Undergone Major Repairs Drive Long Distances?

A vehicle that has undergone major repairs can still be driven long distances, but it's important to ensure that the driving speed is not too fast and to avoid speeding. Most importantly, overloading should be avoided. Carrying too little or too much cargo: When driving at high speeds, a new car should be in a fully loaded state. Therefore, it's necessary to find enough people to match the vehicle's full load mass as specified in the manual. If enough people cannot be found, items can be placed in the trunk to compensate. Going for a high-speed drive before an oil change: High-speed driving not only requires skill but also the right timing. The quality of the engine oil is a direct factor affecting the engine. Therefore, it's crucial not to drive at high speeds before an oil change. During high-speed driving, the engine operates at high RPMs, leading to maximum mechanical wear. The first batch of engine oil contains the most metal shavings and impurities. Using this oil with a high amount of debris for high-speed driving can significantly increase engine wear and even cause abnormal wear.
