The rearview mirror heating switch on the new Mazda 3 is located below the vehicle's air conditioning adjustment area, to the right of the hazard warning light button. The button features a rectangular block with three upward-pointing curved lines. Simply press it to activate the function, provided the vehicle is powered on. Rearview mirror heating is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the surface, gradually removing rain or fog, eliminating the need for frequent manual wiping and reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment knob—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is needed, as the driver's side has a dedicated adjustment button. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature (usually between 35-60°C) within minutes, distributing heat to both left and right mirrors. As the temperature rises, water droplets on the mirror surface shrink due to evaporation, and fog gradually dissipates, effectively clearing frost and condensation. However, in heavy rain, the effect may be less noticeable. Precautions for using the rearview mirror heating function: The heating function relies on electric heating wires embedded in the mirrors, which consume significant power. Ensure the vehicle is running when using this feature to avoid draining the battery, which could prevent the car from starting. Avoid activating it while the car is stationary for extended periods. Other methods to defog rearview mirrors include: Opening windows slightly to create air convection, reducing the temperature difference between inside and outside, which helps dissipate fog. Adjusting the car's air conditioning to blow warm air onto the mirrors for defogging.

How many questions are there in the driving license subject 4 test?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses", there are a total of 50 questions in Subject 4. The test consists of true/false questions (questions 1-20), single-choice questions (questions 20-40), and multiple-choice questions (questions 41-50). The question types include image analysis, animated case studies, and text descriptions. The scope of Subject 4 covers driving knowledge under adverse weather and complex road conditions; identification of common traffic signs, markings, and gestures; knowledge of traffic accident rescue and common hazardous material handling; comprehensive judgment of illegal behaviors and case analysis; knowledge of emergency avoidance; safe driving knowledge; and driving ethics and civilized driving knowledge. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses", there is no limit to the number of attempts for Subjects 1 and 4. If the first test on the day is not passed, a make-up test can be taken on the spot. If it is still not passed, you need to reschedule, and no additional fees are required for the make-up test. However, it should be noted that the validity period of the driving skill test permit is three years. If the applicant does not complete the test within the validity period, the results of the already passed subjects will be invalidated. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driving license assessment. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts: the road test and the addition of a safety and civilized driving knowledge test, commonly known as "Subject 4", which assesses "driving ethics". Subject 4 is the colloquial name for the safety and civilized driving knowledge test under Subject 3 and is not a separate subject. Because this test is conducted after Subject 3, it is commonly referred to as the Subject 4 test. In official terms, there is no Subject 4. The safety and civilized driving knowledge test is conducted after Subject 3. Subject 4 test notes: Test duration: The test lasts 30 minutes, and if you answer 6 questions incorrectly (12 points) during the test, the session will be terminated. Number of questions: Depending on the type of driving license being tested, 50 questions are randomly selected from the corresponding Subject 4 question bank in proportion. For small vehicle licenses, questions are selected from 800, and for large vehicle licenses, from 1023. Each question is worth 2 points. Question types: The test includes single-choice questions (including true/false questions) and multiple-choice questions. The first 45 questions are single-choice, and the last 5 are multiple-choice. The test questions include animated questions, image questions, scenario recognition questions, and text description questions. Make-up test notes: If Subject 4 is not passed, only Subject 4 needs to be retaken. The driving school will schedule the make-up test, and there is no limit to the number of make-up attempts. You can retake the test until you pass, and no additional fees are required for Subject 4 make-up tests. There are a total of 3 subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 3 is divided into two parts. Subject 1 refers to the test on road traffic safety laws, regulations, and related knowledge; Subject 2 refers to the field driving skills test; and Subject 3 refers to the road driving skills and safety and civilized driving knowledge test.
