What does the ON position mean?

ON means on. The car ignition switch has four positions: START, ON, ACC, and LOCK. LOCK is for locking the steering wheel; ACC allows you to turn on some electrical components, such as the radio; ON connects all electrical components in the car, and this is the position used while driving; START is the ignition position for starting the car. The car ignition refers to turning the key. Below is an introduction to some car buttons: 1. "SEL" button: A menu selection confirmation button, usually found on the multifunction steering wheel. 2. "OK" button: It has the exact same function as the "SEL" button, but some cars use "SEL" while others use "OK". 3. "A/C" button: The compressor switch, short for Air Condition, is the air conditioning cooling switch, as car heating does not require the compressor. 4. "VOL+/-" button: Volume adjustment buttons. VOL is the abbreviation for the word "volume", which translates to volume, and it adjusts the car audio volume. 5. "MUTE" button: A mute button for instant muting. 6. "MODE" button: A mode-switching button. 7. "SET" button: On the multifunction steering wheel, it is the cruise control function button.

Why is a 4-wheel alignment necessary?

Reasons for performing a 4-wheel alignment are as follows: 1. Eliminate the adverse effects caused by wheel camber. Wheel camber causes the front wheels to have a tendency to spread outward. Due to the constraint of the axle, they cannot roll outward, leading to the wheels both rolling and sliding, which increases wear. 2. Proper toe-in ensures that the rolling direction of the wheels at every moment is close to straight ahead, reducing the pressure on the wheel hub's outer bearings and tire wear. Principles and steps of 4-wheel alignment: 1. First, adjust the steering angle. The principle of steering angle is to ensure that the angles of turning left and right are the same, guaranteeing equal steering angles in both directions to avoid situations where the left turn angle is larger than the right. Adjustment method: Adjust the relative position of the steering wheel on the steering column to ensure that the number of turns and the angle of the final half-turn are the same when turning left and right. 2. Place the vehicle on a 4-wheel alignment machine and fix the steering wheel in the horizontal straight position, i.e., the position where the car drives straight forward. 3. Adjust the camber angle: The principle of camber angle is to ensure the correct contact surface between the tire and the ground, preventing uneven tire wear. Adjustment method: Loosen the two camber adjustment ball joint screws on each side of the subframe (these are locking screws; it is best to replace them after loosening). Based on the alignment machine data, adjust by generally moving the tire inward. 4. Adjust the toe-in: The principle is to ensure the car has a certain automatic steering return function and maintains the ability to drive straight forward.

Can New Energy Fuel Replace Gasoline?

New energy fuel can replace gasoline. Here are the specific details about new energy fuel: Introduction: New energy fuel refers to products such as "alcohol-based oil" and "hydrocarbon oil". These are methanol-based mixed fuels, which are essentially methanol blended with certain chemical additives like modifiers and stabilizers. Categories: Mixtures of methanol, ethanol, and various other alcohols can all be considered new energy fuels. The combustion value of new energy fuel is comparable to that of liquefied petroleum gas (LPG), making it a viable alternative to LPG and fuel oil. Moreover, the exhaust emissions after combustion are over 80% lower than those of liquefied petroleum gas.

What is the deadline for registering a newly purchased electric motorcycle?

Motorcycles must be registered within three months. Here are the details: Motor Vehicles: Motorcycles are classified as motor vehicles, which means they must be registered before they can be driven on the road. According to the Road Traffic Safety Law, all motor vehicles, including motorcycles, must be registered with the traffic management authorities within three months from the date of purchase. Late Fees: If registration is not completed within three months, late fees will be incurred. Additionally, the invoice for a motorcycle remains valid until the vehicle is scrapped, which is typically after 15 years. If the motorcycle is not scrapped, the invoice remains valid indefinitely. To avoid late fees, owners should promptly visit the vehicle management office to register and license their motorcycles.

Can I skip a question I don't know in Subject 4 and move to the next one?

For questions you don't know in Subject 4, you can choose to skip to the next question. In fact, the approach for Subject 4 is the same as for Subject 1, just relatively more challenging. The Subject 3 test consists of two parts: besides the road test, it includes the Safety and Civilization Knowledge Test, commonly known as "Subject 4," which assesses "driving ethics." The test paper consists of 50 questions, mainly in the form of case studies, images, animations, etc., with a full score of 100 and a passing score of 90. Below is an introduction to the other test subjects: 1. Subject 1: Also known as the theoretical test or driver's theory test, it is part of the motor vehicle driver's license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and other related knowledge. The test format is computer-based, with 100 questions, and a passing score of 90 or above. 2. Subject 2: Also known as the small road test, it is part of the motor vehicle driver's license assessment and refers to the field driving skills test. For small vehicles C1 and C2, the test items include five mandatory components: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as S-turns). 3. Subject 3: Includes the road driving skills test and the safety and civilization driving knowledge test, which are part of the motor vehicle driver's license assessment. The content of the road driving skills test varies depending on the type of vehicle being licensed.
