Engine Overheating and Stalling Due to Water Shortage?

What Principle Does the Reversing Radar Use?

Reversing radar operates on the principle of ultrasonic distance measurement, which is designed and developed based on how bats fly at high speeds in the dark without colliding with any obstacles. The reversing radar consists of components such as ultrasonic sensors (probes), a controller, and a display (or buzzer). Under the control of the controller, the sensor emits ultrasonic signals. When encountering an obstacle, an echo signal is generated. The sensor receives the echo signal, and the controller processes the data to determine the position of the obstacle. The display then shows the distance and issues other warning signals, providing timely alerts. This allows drivers to have a clear "measure" while reversing, making the process easier and safer. The reversing radar is an auxiliary device for car parking. It informs the driver about obstacles behind the vehicle through sound or a more intuitive display, eliminating the troubles caused by nearsightedness when parking or starting the vehicle. It also helps drivers eliminate blind spots, enhancing driving safety. After installing a reversing radar, the driver no longer needs to look back to know if there are obstacles behind the car. It can also display the exact distance of obstacles and provide timely warnings within a dangerous range, avoiding hazards caused by poor rear visibility. It is particularly useful for unseen steps, low walls, railings, parking in tight spaces, and nighttime reversing. In the past, reversing radar products were only suitable for installation on sedans and became standard equipment for high-end cars. Now, new-generation reversing radars have seen significant improvements in probes, making them compatible with various vehicle types such as station wagons, MPVs, jeeps, or off-road vehicles with added bumpers. This has led to the gradual popularization of reversing radars in other vehicle categories. Additionally, modern reversing radars not only provide audible alerts but also allow optional displays to show the scene behind the vehicle, indicating distance and judging direction. The sound alarm features an adjustable switch, allowing users to increase, decrease, or turn off the sound based on personal preference.

How many days after applying window film can you open the windows?

After the car window film installation is completed, you can open the windows after 3 days in summer and 7 days in winter. Here are some precautions to take after applying car window film: 1. Parking matters: When parking the vehicle, choose a sunny location to ensure the moisture inside the film evaporates fully. 2. Car washing matters: Do not wash the car within three days after applying the film to avoid potential detachment caused by water. Therefore, it is advisable to wash the car before applying the film. 3. Installation matters: If there are stains on the car window film, never use sharp or hard objects to scrape them, nor use harsh chemical solvents to wipe them. It is recommended to gently clean with a clean damp cloth, sponge, or soft fabric.

What does it mean when it shows 'driver training not attended'?

Students must complete the required number of training hours before they can register for the exam; otherwise, they are not allowed to take the test. This is a mandatory regulation, and the driving school's approach is correct. The "Motor Vehicle Driver Training and Examination Syllabus" jointly issued by the Ministry of Public Security and the Ministry of Transport states: student training is divided into three stages, and each stage must complete the specified number of training hours. Only after passing the assessment can students proceed to the next stage of training; those who fail the assessment need to increase the content and hours of retraining for that stage. There may be several reasons for this situation: 1. Insufficient driving lessons. 2. Incomplete information has not yet been entered into the system, so it is temporarily not possible to schedule the exam. 3. The subject hours have not been reviewed, and the exam can be scheduled after the review. 4. Due to updates in the vehicle management office system.

Why Can't the Car Start After Stalling in the Rain?

Vehicle stalling after wading through water indicates that the engine has taken in water. Below is an introduction to water-damaged vehicles: 1. Specific definition of a water-damaged vehicle: The vehicle begins to accumulate water, and internal components suffer damage due to the water. Water-damaged vehicles are also classified into different flood levels. 2. Classification of flood levels for water-damaged vehicles: Flood level 1 is when water just reaches the vehicle's chassis, flood level 2 is when water reaches half of the wheels, flood level 3 is when water almost completely submerges the tires, flood level 4 is when water reaches the engine hood, flood level 5 is when water completely submerges the engine hood, and flood level 6 is when water submerges the roof.

What does it mean to pledge the green book but not the car?

Pledging the green book but not the car refers to auto title loans. Vehicle safety is an aspect of automobiles that cannot be overlooked. Attention must also be paid to vehicle safety when applying for car loans. Below is a detailed introduction regarding vehicle safety: 1. Overview: For vehicles, automobile safety is primarily divided into two major aspects: active safety and passive safety. Active safety involves controlling the vehicle as smoothly as possible. Whether it's braking and accelerating in a straight line or steering left and right, operations should be as stable as possible to avoid deviating from the intended path and to ensure the driver's visibility and comfort are not affected. 2. Others: The scope of automotive safety technology is becoming increasingly broad and detailed, developing towards integration, intelligence, systematization, and universalization. Strictly controlling speed during nighttime driving is a fundamental measure to ensure safety.

What does the yellow exclamation mark on the Highlander dashboard mean?

When a yellow exclamation mark appears on the car dashboard, it can indicate four possible situations: general faults, automatic transmission faults, abnormal tire pressure, or lighting faults. Below is a detailed analysis of these four scenarios: General Faults: A triangle with an exclamation mark inside indicates a malfunction in the car's general performance, components, or functions. Common causes include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission malfunction or transmission fluid level below the normal range. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark inside a horizontal line under a bracket represents the tire pressure monitoring warning light. This light turns on when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible. Alternatively, you can check yourself, focusing on commonly used bulbs such as turn signals, fog lights, or interior lights, to identify the problem. There is also a red exclamation mark inside a circle with parentheses, which represents a brake system warning. It mainly indicates brake system failure or low brake fluid level. The brake system should be inspected immediately to avoid accidents.
