Free four-wheel drive means that when the wheel hub lock is in the FREE position, the vehicle is in two-wheel drive mode, disconnecting the front wheels from the front half-shafts; when in the LOCK position, it is in four-wheel drive mode. Below is some information about four-wheel drive vehicles: 1. Definition: A four-wheel drive vehicle is one with interconnected front and rear differentials that drive all four wheels. Since the engine's power is transmitted to all four tires, all wheels can provide traction. In a regular two-wheel drive vehicle, if one driving wheel slips, the other driving wheels will also lose power. 2. Drive configuration: Drive configuration refers to the arrangement of the engine and the number and position of the driving wheels. Most vehicles have two rows of wheels, front and rear. The wheels that are directly driven by the engine to push (or pull) the vehicle forward are the driving wheels. The most basic classification is based on the number of driving wheels, which can be divided into two-wheel drive and four-wheel drive.

When I go camping in the suburbs by car, I heavily rely on my 4WD vehicle because its all-wheel drive system delivers power to each wheel, especially on muddy or snowy roads where the car won't slip easily. It's far superior to regular two-wheel-drive cars—for example, when crossing waterlogged roads on rainy days, others might get stuck while I pass through steadily. Many people think 4WD is designed for off-roading, but it's actually useful in cities too, especially for safer starts at slippery intersections. Just remember not to overuse it; the default mode saves fuel, and you should only switch to 4WD when necessary. Maintenance-wise, tire wear is more even, but the drivetrain is more complex, so upkeep costs are higher. Overall, my 4WD gives me more freedom to go out without worrying about bad weather.

How to put out an engine fire in Subject 4?

When the engine catches fire, quickly shut off the engine and use a fire extinguisher or the covering method to put out the fire. Do not open the engine hood to extinguish the fire, as opening it may allow a large amount of air to enter and intensify the flames. If the fire is too large, leave the area quickly to avoid danger. Causes of engine fires: 1. Transmission oil leakage: When encountering complex road conditions, the car's transmission may generate a large amount of heat due to increased load, and leaking oil may spray onto high-temperature components, igniting the vehicle. 2. Fuel leakage: Fuel is the most flammable of all fluids, and fuel leakage is the most direct factor leading to car fires or even explosions.

Can the original owner be absent during motorcycle ownership transfer?

Motorcycle ownership transfer can proceed without the original owner present, but requires a power of attorney designating an agent to sign on their behalf. However, some stricter jurisdictions mandate the owner's physical presence. Since requirements vary by local vehicle management offices, please confirm with the on-site service window. Below are the required documents for transfer: 1. Seller: Vehicle registration certificate, valid vehicle license (within inspection period), original purchase invoice (or previous transfer receipt), owner's ID (for organizations, provide corporate code certificate); 2. Buyer: Owner's ID (organizations must provide corporate code certificate). 3. Authorized agent: The agent must possess local ID or temporary residence permit, and complete a power of attorney to process the vehicle registration transfer.

How often should new car tires be replaced?

Car tire replacement mainly depends on mileage and years of use. Under comprehensive road conditions, tires should be replaced every 30,000-50,000 kilometers, or every 3-5 years. Below is relevant information: 1. Tires undergo prolonged friction with the ground, causing the rubber to age. When cracks appear on the tires, replacement measures must be taken to avoid potential safety hazards. It is recommended to have them inspected every six months after about 5 years of use. If the wear is severe and the balance feels off, replacement is necessary at this point. 2. Generally, tire dealers do not specify a clear time frame, but it is advisable to use them for at least three years, up to about five years. If the mileage reaches 30,000-50,000 kilometers, the tires should be replaced.

What are the methods to resolve the P0337 fault code?

Fault code P0336 indicates a circuit malfunction in the crankshaft position sensor. This fault is sporadic and can be resolved by simply replacing the 7X crankshaft position sensor harness. Below are the steps to clear the P0336 fault code: 1. After troubleshooting the vehicle, it is necessary to clear the fault code. When clearing the fault code, strictly follow the specific method designated for the particular vehicle model. 2. Avoid randomly using the method of disconnecting the battery negative terminal to clear the fault code. Carelessness may lead to two abnormal conditions: first, it may cause the adjustment center of some vehicle models to lose normal records. Most vehicle computers have an automatic memory function, and if the battery negative terminal is disconnected, useful engine operation data stored in the memory will be erased. 3. Secondly, the above method may result in the loss of some normal functions, such as the common example of audio system lockout.

What to Do When the Car Battery Dies and the Mechanical Lock Won't Open the Door?

Here are the solutions when the car battery dies and the mechanical lock won't open the door: 1. Jump-start the vehicle: Try crawling under the car and using a tool to hook the actuator of the engine hood from below, then open the hood to get a jump-start from another car, which will allow you to open the door. 2. Use the key to open the passenger door: Some models allow both the driver and passenger doors to be opened with a mechanical key. If the driver door cannot be opened, the lock cylinder may be damaged. In this case, try opening the passenger door to enter the car. Below are the reasons why the mechanical lock won't open the door: 1. Mechanical key mismatch: If the key has just been replaced, the new key may not match the lock cylinder, preventing the door from opening. 2. Frozen door: In winter, if it snows overnight, the low temperature can freeze the door shut. In this situation, even if the lock cylinder is unlocked, the door won't open. 3. Faulty lock cylinder: If internal parts of the lock cylinder are broken, the key may turn but the door won't open.

How to eliminate the ABS warning light displayed on the car?

"ABS" stands for "Anti-lock Braking System". The methods to eliminate the ABS warning light displayed on the car are as follows: 1. Visit a 4S shop for professional repair and use a computer to clear the fault code. 2. You can try to diagnose and eliminate the fault cause by yourself. The reasons that may cause the ABS light to turn on are as follows: 1. The battery voltage is too low. Check whether the battery voltage is at 12V. 2. ABS circuit fault. Check the relay and ABS control circuit to see if there are broken wires, loose interfaces, or relays not installed firmly. 3. Check the fluid level in the brake master cylinder reservoir. If the fluid level is too low, add brake fluid to bring the level back to the normal range. 4. Faulty wheel speed sensor. Check the four wheel speed sensors for any foreign objects.
