The function of the car radar is to detect the distance between the vehicle body and other vehicles or obstacles, and to inform the driver of the surrounding situation through sound or display, thereby avoiding unnecessary friction or collisions during parking or reversing. The reasons for radar malfunction include: 1. Failure of the buzzer or display; 2. Damage to the reversing radar circuit; 3. Loose connection between the buzzer or display and the main unit. The working principle of the radar is: under the control of the controller, the sensor emits ultrasonic signals. When encountering an obstacle, an echo signal is generated. After the sensor receives the echo signal, the controller processes the data to determine the position of the obstacle. The distance is then displayed on the display, and a warning signal is issued to achieve the purpose of safe parking.

What kind of engine oil does the Changan CS55 use?

Changan CS55 uses 5w-40 synthetic engine oil. More information about engine oil is as follows: 1. The engine is the heart of a car, containing many metal parts that move against each other in friction. These components operate at high speeds, in harsh environments, and under elevated temperatures. 2. Engine oil serves to lubricate and reduce wear, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. 3. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties. Additives compensate for and improve the shortcomings of the base oil, imparting new characteristics, making them an essential part of lubricating oil. 4. Different grades of lubricating oil must not be mixed in the Changan CS55. The use of engine oil additives or other engine maintenance products is strictly prohibited, as they may damage the engine under certain circumstances and affect the warranty. Do not use engine oil that does not meet specifications and requirements, as it may lead to increased fuel consumption, reduced power, or even engine damage, affecting the warranty. Replace the engine oil and oil filter at the intervals or mileage specified in the manual to ensure optimal driving experience and engine longevity.

What causes severe shaking when parked in D gear?

Here are the reasons for severe shaking when parked in D gear: 1. Severe shaking when parked in D gear may indicate transmission issues, such as deteriorated or damaged transmission fluid, worn or loose transmission bearings, or bearing failure. 2. Excessive carbon buildup in the engine may require throttle body cleaning. 3. Problems with the fuel system, ignition components, or engine mounts can also cause severe shaking when parked in D gear. Here are solutions for D gear parking shake: When there's excessive carbon buildup inside the engine, the fuel injected by the cold start injector gets largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making the engine hard to start. In this situation, the engine will only start easily after the carbon deposits have absorbed enough fuel to reach saturation.

How to Remedy Incorrect Gear Shifting in Subject 3?

Here are the remedial measures for incorrect gear shifting in Subject 3: 1. If you shift into the wrong gear in Subject 3 but act quickly enough to immediately shift into the correct gear, you can avoid point deductions. 2. If you intended to shift into 2nd gear but shifted into 3rd gear instead, promptly return the gear lever to the neutral position and quickly shift back to 2nd gear. Of course, the time between shifting into the wrong gear and correcting it must be sufficiently short. 3. The computer system uses various sensors to monitor signals. Mismatched gears leading to excessively high RPMs, jerking, etc., can be instantly detected, resulting in a failed test. Solutions for incorrect gear shifting: 1. When accelerating from 2nd to 3rd gear, first shift into neutral, leaving the gear lever in the neutral position for about one second, then pull it straight up—this will engage 3rd gear. 2. When upshifting or downshifting, avoid shifting in one continuous motion. Instead, leave the gear lever in neutral for about one second before moving it to the intended gear to reduce mistakes. 3. Use gentle movements when shifting; accuracy is more important than force. Practice gear shifting frequently, and you can perform gear-shifting exercises in the car to develop a feel for it.
