What does it mean to turn off four-wheel drive?

What is the phenomenon of steering wheel movement when driving on a straight road?

Turning the steering wheel is a rotational phenomenon, which involves rotation around a fixed point. The steering wheel is generally connected to the steering shaft via splines, and its function is to convert the force applied by the driver to the edge of the steering wheel into torque, which is then transmitted to the steering shaft. When using a larger-diameter steering wheel for turning, the hand force required from the driver can be reduced. Composition of the steering wheel: 1. Frame: The frame is usually made of zinc alloy or aluminum alloy, and some manufacturers are experimenting with cheaper and lighter magnesium alloys. The frame is produced through die-casting. A few manufacturers still use steel sheet metal for the frame, resulting in a more complex structure. 2. Foam: The foam material is generated in a foaming machine, with the frame fixed in the foaming machine during production.

What Causes Windshield Fogging When Using Air Conditioning?

Windshield fogging when using air conditioning is caused by the significant temperature difference between the interior and exterior environments. Solutions for windshield fogging: 1. Front windshield defrosting: Generally, based on the driving environment, the front windshield defrost function can be used to treat the front windshield. If equipped with automatic air conditioning and the ability to select air vent positions, it is recommended to choose the front windshield and central vent positions and turn on the rear windshield heating function. This way, the temperature inside the vehicle is continuously regulated, preventing fogging. 2. Rear windshield heating: If it is not possible to select both directions for air flow simultaneously, turn on the front windshield defrost function and the rear windshield heating function. If the side windows fog up, slightly opening the windows can quickly remove the fog. After closing the windows, once the interior temperature rises, no fog will form.

Can a Spare Tire Run at 100 km/h on the Highway?

Automobile spare tires are divided into two categories: full-size spare tires and non-full-size spare tires. If it is a full-size spare tire, since the size of the original tire and the full-size spare tire are the same, there will be no restrictions on the mileage and speed of the vehicle using the spare tire, and it can run at 100 km/h on the highway. However, if the spare tire is a non-full-size spare tire, the driving speed should not exceed 80 km/h, and when replacing the spare tire, it can only be used on non-driving wheels. For more details, please see the following: 1. The difference between the spare tire and the original tire: The full-size spare tire has exactly the same specifications as the other four tires on the vehicle and can replace any one of the temporarily or completely unusable tires. The non-full-size spare tire has a slightly smaller diameter and width than the other four tires and can only be used as a temporary replacement, and only on non-driving wheels. 2. Additional information: The spare tire is actually for emergency use and is not a tire for long-term use. Regardless of the width of the spare tire, manufacturers have special production and usage requirements. Since the spare tire is not used for long-term operation on the vehicle and has no wear, a tire without wear is different from a tire that has been worn out. Using a spare tire on the vehicle inherently carries certain safety risks.

How Many Years Can Private Car Tires Last?

Private car tires can last for 5 years, but they need to be replaced based on actual conditions. Here are the details: Replacement time depends on the situation: If driving under harsh road conditions, such as frequently traveling on gravel roads or often encountering traffic jams, sudden braking, or sharp turns, the replacement interval for tires will be shortened. Tire aging time: The main material of tires is rubber, which undergoes natural aging. This primarily manifests as the tire hardening and the sidewalls developing small cracks. Generally, natural aging occurs within 4-5 years. Tires used for 5 years should be replaced promptly to prevent the risk of blowouts. Observe tire wear: If the tire wear is severe, and the tread pattern has reached the same level as the wear indicators, the tires need to be replaced. Otherwise, braking on wet or slippery roads will be more difficult, and the vehicle may easily lose control. Additionally, driving on excessively rough roads increases the risk of blowouts.

What are the tips for handling 12-point violations on highways?

If the driver's license is Class C, a one-time deduction of 12 points requires retaking the subject one exam. After passing the exam, the driver's license can be reinstated. For Class A or B licenses, the penalties are more severe, involving not only retaking the exam but also a downgrade of the license. Below are specific details about driver's licenses: 1. Classification: The Ministry of Public Security officially issued the "Regulations on the Work of Motor Vehicle Driver's License Services," introducing a grading system for motor vehicle driver's licenses. Licenses are divided into 15 classes: A1, A2, A3, B1, B2, C1, C2, C3, C4, D, E, F, M, N, and P. 2. Renewal Rules: If a driver does not accumulate 12 points in any scoring cycle during the six-year validity period of the motor vehicle driver's license, the license can be renewed for a ten-year validity period. If the driver does not accumulate 12 points in any scoring cycle during the ten-year validity period, the license can be renewed for a long-term validity period.

How much discount does highway ETC offer?

Highway ETC generally offers a nationwide uniform discount of 5% off. The specific discount may vary depending on the region, and bank promotions are also time-limited. How ETC works: Through the on-board electronic tag installed on the vehicle's windshield, it communicates with the microwave antenna in the ETC lane at the toll station via dedicated short-range communication. It uses computer networking technology to conduct background settlement processing with the bank, thereby achieving the purpose of vehicles passing through highway or bridge toll stations without stopping to pay tolls. ETC usage precautions: The ETC transaction sensing area is 8 meters. When the vehicle in front stops, to prevent the ETC device of the front vehicle from malfunctioning or not having an ETC device at all, keep a distance of more than 10 meters from the front vehicle to avoid automatic sensing and paying for the front vehicle. The recognition speed for ETC lane passage is 20km/h. If the speed is too fast, the vehicle device information cannot be read, which will also lead to payment failure. Unauthorized disassembly or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will cause the electronic tag to fail. It can be sent to the bank where the ETC card was issued or the highway service office for inspection. If the detachment or loosening is not caused by human factors, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also lead to payment failure. Follow the guidance of on-site staff to go to the manual MTC lane and pass using cash or card. If the vehicle's windshield is too thick, it may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after an accident or those with modified front windshields.
