Methods for properly turning on the car air conditioning in summer: 1. Open the windows before turning on the air conditioning. After the car has been exposed to the sun in summer, do not enter the vehicle immediately. Alternatively, after entering the car, do not rush to turn on the air conditioning. Instead, lower all the windows or open the doors first, then turn on the fan to accelerate air circulation. Close the windows and turn on the air conditioning after a few minutes. 2. Direct the air conditioning vents diagonally upward. Most people do not pay much attention to this. The correct way is to choose the diagonal upward direction, allowing the cold air to cool the car from top to bottom. 3. Avoid prolonged low temperatures. While driving, car owners should also be careful not to excessively pursue coolness by setting the car air conditioning temperature too low. Otherwise, people can easily suffer from endocrine disorders due to the large temperature difference between the inside and outside of the car, making them prone to illness.

How soon can a car be driven after a small area touch-up paint job?

Small area touch-up paint jobs can typically be completed within a few hours, and the vehicle can usually be driven on the same day after the paint has been applied. However, it is important to avoid exposing the touched-up areas to corrosive cleaning agents such as adhesive removers or tar removers, as these can completely dissolve the newly applied paint. Below is some relevant information about automotive paint: 1. Function: Automotive paint is a protective film sprayed onto cars, serving as a type of coating that helps prevent corrosion of the vehicle body. 2. Precautions: Always refer to safety technical data before use; thoroughly stir the paint before application to ensure uniform color; wear appropriate protective gear, including a respirator and work clothing, during use.

Can I Watch the 990 Minutes of Subject 1 Freely?

According to the "Motor Vehicle Driver Training Teaching Outline," completing 12 class hours is sufficient to schedule the Subject 1 exam. Here are the relevant details: 1. Subject 1: The primary learning method is practicing questions, as the questions on the software are the same as those in the exam, only arranged differently. Watching videos mostly serves as basic road traffic safety warning education for candidates, so whether you watch them carefully or not has little impact. 2. Scheduling: As for how long after watching the videos for Subject 1 you can schedule the exam, it actually depends on whether the 12 class hours have been completed. Once the 12 class hours are met, the system typically reviews the application within 1-3 working days, and upon approval, you can proceed to schedule the exam.

Where can ETC be installed?

The ETC installation position is generally in the upper middle part of the front windshield for most vehicles, while for large vehicles like trucks and buses, it is installed in the lower middle part. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket anti-explosion films, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave window area. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide valid identification and the original and photocopy of the vehicle registration certificate. If the application is not made by the owner, the agent's valid identification is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is also required, and the vehicle must be registered under the name of an individual aged 18 to 60. For company vehicles, the required documents include: An introduction letter from the vehicle owner (with official seal); a photocopy of the organization code certificate or business license (with official seal); the original ID of the agent; the original vehicle registration certificate; and the vehicle that needs to apply for ETC. Here are some precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, which can reduce the driver's field of vision. If ETC is installed without considering this, it may increase the driver's blind spots. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power, but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it casually: The button in the middle of the adhesive is an anti-removal lever, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-removal lever in. If it is removed casually, the anti-removal lever will pop out and trigger the switch, locking the electronic tag and making it unusable. In this case, you need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing area is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic payment for the vehicle in front. The ETC lane recognition speed is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, leading to payment failure. When using a debit card bound to ETC, insufficient balance will also cause payment failure.

Where does the second chance in Subject 3 start from?

The rule for the second chance is that if you fail the first time in the lighting test, you have to retake the entire exam. If you fail the road test, you start the retest from the point where you failed. Below are the relevant details: 1. Lighting: Subject 3 first tests the lighting before the road test. If you fail the lighting test, you lose one chance, and both the lighting and road tests must be retaken. If you only fail the road test, then you retake the road test from the point of failure, and the lighting test does not need to be repeated. 2. Road Test: Retaking the road test is simple. Wherever you fail, you pause first to listen to instructions. Except for the lighting test, all other steps of the road test must be retaken from the beginning, completing all the test items. The Subject 3 exam follows the principle of one registration with two chances. If your score is below 90 in the first attempt, you fail, and the second attempt requires starting from the beginning, completing all test items and redoing all previous actions.

What is the difference between 'application in progress' and 'acceptance in progress' for Subject 2?

Application refers to when the student submits the request, but the vehicle management office has not yet received it. Acceptance in progress means the vehicle management office has received the application and is verifying eligibility. Below are relevant details: 1. Appointment: 'Application in progress' means queuing for an appointment. Generally, the review time for a Subject 3 appointment takes 5-10 days. In first-tier cities, where there are many applicants, the time may be extended, with notifications typically sent 3-5 days before the exam at the latest. 2. Acceptance in progress: Some students may see the system continuously displaying 'acceptance in progress' when making an appointment. This is usually due to system errors or delays. Normally, a successful appointment will trigger an SMS notification. If you receive the SMS, you can attend the exam on the scheduled day. Alternatively, you can directly call the local vehicle management office to confirm whether the exam appointment was successfully made.
