Is the Corolla a Class B car?

Why does the car make a squeaking sound when the air conditioning is turned on?

Compressor belt tensioner wheel damage; compressor malfunction; internal and external circulation motor failure. Diagnostic methods: 1. Lack of lubrication: When the compressor electromagnetic clutch engages, it produces a metal friction sound. The fault is usually due to a lack of lubricating refrigerant oil inside the compressor. When there is insufficient refrigerant oil, the internal piston of the compressor does not receive adequate lubrication, resulting in metal friction sounds under the high pressure of the refrigerant. 2. Electromagnetic clutch failure: Another scenario is a malfunction in the electromagnetic clutch itself, where the internal bearing is damaged and produces abnormal noises. In this case, the compressor must be replaced. If there is a lack of refrigerant oil, it is necessary to first recover the refrigerant from the air conditioning system, evacuate the system, refill with sufficient refrigerant oil, then recharge with refrigerant, and run the car with the air conditioning on for a while to allow the refrigerant oil to circulate fully through the system. 3. High pressure: The air conditioning belt makes abnormal noises when the air conditioning is turned on. This situation occurs when the air conditioning system pressure rises rapidly upon turning on the air conditioning.

Can a C1 license be upgraded to A2 after six years?

Regardless of how many years you have held a C1 driver's license, you cannot directly obtain an A2 license. To acquire an A2 license, you must enroll in a driving school and upgrade your license through additional training. If you currently hold a C1 license, you must first upgrade it to a B1 or B2 license. Then, you can further upgrade from B1 or B2 to A2. The conditions for upgrading to B1 or B2, using B2 as an example, are as follows: 1. Hold a C1 license for at least one year (B1 requires three years); 2. Be between 20 and 50 years old (B1 requires 21 years or older). 3. Have no record of accumulating 12 penalty points in the most recent scoring cycle before application (B1 requires three cycles). The conditions for upgrading to A2 are: 1. No pending traffic violations, otherwise, the upgrade application cannot be processed. 2. Hold a B1 license for at least three years or a B2 license for at least two years. 3. Be between 22 and 50 years old. 4. Have no record of accumulating 12 penalty points in the three consecutive scoring cycles before application.

How to Fix a Car Battery That Won't Charge?

If the battery has been used for a short period and has mild sulfation on the plates due to short-term over-discharge, it can be repaired using a desulfation charging method. However, the battery's capacity can only be restored to about 80% of its rated capacity. For batteries that have been used for a long time (over three years), there is generally no repair value, and it's better to replace them directly with new ones. Types of car batteries: 1. Conventional Battery: The plates of conventional batteries are made of lead and lead oxide, with the electrolyte being an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low cost. 2. Dry-Charged Battery: Its full name is dry-charged lead-acid battery, and its main feature is that the negative plate has a high capacity for storing electricity. In a completely dry state, it can preserve the obtained charge for up to two years. 3. Maintenance-Free Battery: Due to its structural advantages, maintenance-free batteries consume very little electrolyte and basically do not require the addition of distilled water during their service life. They also feature resistance to vibration, high temperature, compact size, and low self-discharge. Their service life is generally twice that of conventional batteries.

What does it mean when a car displays 'Check Transmission'?

A car displaying 'Check Transmission' indicates a malfunction in the transmission system. During prolonged use, due to frequent gear shifts, the components inside the transmission inevitably undergo wear and deformation, leading to issues such as difficulty in shifting gears, automatic gear disengagement, and unusual noises during operation, which affect its performance. Common transmission faults include: 1. Difficulty in shifting: When operating the gear lever, it feels strenuous to shift gears, and the gears cannot engage smoothly. A grinding noise may occur during shifting, and in severe cases, the gears may not engage at all. 2. Automatic gear disengagement: There are two common scenarios for automatic gear disengagement. One is when the gear jumps back to neutral upon slightly releasing the accelerator pedal while driving. The other occurs when climbing a hill under heavy load, where the gear immediately jumps back to neutral. In such cases, if attempting to re-engage the gear fails, it can easily lead to the vehicle rolling back, potentially causing serious accidents. 3. Transmission noise: Unusual noises from the transmission can occur in two situations. One is when the noise appears in neutral position, and the other is when the noise occurs during gear shifts while driving.

What procedures are required for out-of-town annual review of driver's license?

Out-of-town annual review of driver's license requires an out-of-town annual inspection authorization letter. To issue this authorization letter, you need the original vehicle registration certificate and the original driving license of the car, as well as the original compulsory traffic insurance policy and ID card. Below are the relevant details: 1. Annual review time: The annual inspection time of the car is determined based on the date of the new car's registration. If the initial registration date on the driving license is May, the annual inspection time of the car is also every May. The owner can apply for the inspection qualification mark at the vehicle management office of the registration place three months before the expiration of the motor vehicle inspection validity period, and can participate in the annual inspection in advance. 2. Annual review precautions: Before the annual inspection of the car, you need to check whether there are any violations of the vehicle. If there are any, they need to be dealt with in time to avoid affecting the normal progress during the annual inspection. When conducting the annual inspection of the car, you need to choose a good weather day. Try not to go for the annual inspection on snowy or rainy days, as the wheels cannot detect normal braking force when wet. When conducting the annual inspection of the vehicle, you need to carry the driving license, the owner's ID card, insurance policy, compulsory traffic insurance policy, etc. Bringing all the materials can avoid trouble during the annual inspection. Check the trunk, the triangular warning sign must be carried. If you don't have one, you need to purchase it in time to avoid affecting the normal annual inspection due to some details.

What does non-green label vehicle mean?

Green label vehicles refer to gasoline vehicles that meet the National I standard or above and diesel vehicles that meet the National III standard or above in terms of exhaust emission environmental inspection, and are issued green environmental protection labels by the environmental protection department. The establishment of yellow label vehicles and green label vehicles is to alleviate urban traffic congestion and air pollution, and promote the elimination of old vehicles. The "green label" also has a validity period. After the expiration of the environmental protection label, the vehicle must undergo exhaust emission testing according to regulations and obtain a new label based on the results. Non-green label vehicles are those that do not meet these requirements. Precautions for highway driving: 1. Drive in the designated lane: Highways have clearly marked lanes, including dedicated lanes for large vehicles, small vehicles, etc. When overtaking, once you occupy a lane, return to your own lane promptly after completing the overtaking maneuver, and do not occupy other lanes for an extended period. Additionally, emergency lanes should not be occupied for long periods without special reasons. 2. Maintain a safe speed and avoid speeding: The dangers of speeding are well-known, whether on local roads or highways, it can lead to irreversible consequences. 3. Maintain a safe longitudinal distance between vehicles: Under normal conditions, on dry roads with good braking, the distance between vehicles (in meters) should not be less than the speed (in km/h). For example, at 80 km/h, the distance should be no less than 80 meters, and at 100 km/h, no less than 100 meters. Always pay attention to roadside distance markers. In rainy, foggy, snowy, or wet road conditions, the distance should be more than doubled. 4. Pay attention to traffic signs: Always be aware of roadside and overhead signs and markings while driving, and keep to the right appropriately to avoid running over the right lane divider, allowing sufficient lateral distance for overtaking vehicles. 5. Do not arbitrarily occupy emergency lanes in case of traffic accidents: Traffic accidents are inevitable on highways. If other vehicles cause a traffic jam, do not occupy the emergency lane arbitrarily, as it may prevent rescue vehicles from performing their duties. 6. Avoid fatigued driving and take timely breaks: Fatigued driving is extremely dangerous on highways. When fatigued, a person's reaction ability decreases, making it difficult to respond correctly to sudden situations.
