What are the precautions during driving?

During driving, it is important to adjust the seat and rearview mirror positions, release the handbrake, and avoid coasting in neutral at high speeds. The following are the precautions during driving: 1. Adjust the seat and rearview mirror positions: Seat adjustment is for comfort and safety. Rearview mirror adjustment is to eliminate blind spots. The rearview mirror should not only show the traffic conditions behind and on both sides of the vehicle but also appropriately reflect the vehicle itself. This can be more beneficial for reversing and parking. 2. Release the handbrake: Beginners often make the mistake of forgetting to release the handbrake when starting the car cold. It is recommended that beginners develop the good habit of "releasing the handbrake as soon as the car moves" to avoid vehicle damage and personal distress. 3. Avoid coasting in neutral at high speeds: A car maintenance expert once said that the braking distance when coasting in neutral at low speeds is not much different from that when in gear. Some experienced drivers coast in neutral not to save fuel but to prevent the vehicle from stalling. New drivers should reasonably learn and distinguish between different driving habits.

How to Identify Forged and Cast Wheels?

Here are some tips for distinguishing between forged and cast wheels: 1. Different wheel weights: (1) Forged wheels are made through high-strength forging, so under the same size and style, forged wheels are lighter. (2) Some cast wheels imitate the characteristics of forged wheels in appearance. However, there are significant differences in metal properties between the two. Forged wheels have higher fatigue resistance, impact resistance, and strength compared to cast wheels. There is not much difference in heat dissipation function between the two. But generally, qualified cast wheels are about 20% heavier than forged wheels. 2. Different styles: (1) Forged wheels, such as two-piece or three-piece types, are usually assembled with rivets or welding (argon welding). There is often a noticeable color difference between the rim and spokes, making it easy to identify. (2) Cast wheels are formed in one piece and have no color difference. (This method may not always apply, as there are also one-piece forged wheels.) 3. Different tapping sounds: This is the tapping method. Use a small metal rod to tap the wheel. Forged wheels produce a crisp and clear sound, while cast wheels produce a dull and muffled sound.

What Does the Teapot Symbol on the Dashboard Mean

The teapot symbol on the dashboard is the oil pressure warning light. Below are the reasons why it may illuminate: 1. Insufficient Lubricant: Insufficient amount of lubricant in the oil pan; 2. Improper Valve Adjustment: Incorrect adjustment of the oil pressure limiting valve; 3. Filter Issue: Damage to the lubricant filter gasket; 4. Lubricant Inlet Pipe: Loose connection or rupture of the lubricant inlet pipe. Below is additional information on the functions of engine oil: 1. Reducing Friction and Wear: Minimizing friction and wear on moving parts; 2. Removing Sludge and Paint: Clearing sludge and paint deposits from the engine; 3. Neutralizing Acids: Neutralizing acids produced from fuel and lubricant oxidation; 4. Improving Piston Ring Performance: Enhancing the sealing of piston rings and cooling the engine by dissipating heat from moving parts.

Does turning on the heater when starting the car consume more fuel?

Turning on the heater when starting the car does not consume more fuel. Here are some considerations regarding using the car heater: 1. No need to activate the compressor: The car heater used in winter is a non-independent residual heat heating system, which utilizes the heat emitted by components like the radiator and exhaust pipe to warm the air, which is then blown into the cabin by the fan. Therefore, using the heater does not require activating the compressor. 2. Avoid turning on the heater immediately: Since the water temperature in the radiator is still low when the car is just started, you need to wait for the water temperature to rise before warm air can be blown out. Moreover, turning on the heater at this time not only results in cold air but also increases the engine's burden, causing the water temperature to rise more slowly. Therefore, it is advisable to let the car run for a while and wait until the water temperature gauge reaches half of the normal operating temperature before using the heater. Additionally, after turning on the heater, use the external circulation first to refresh the air inside the cabin, then switch to internal circulation after a few minutes. 3. Using the heater does not increase fuel consumption: The heater relies on heat exchange from components like the radiator and exhaust pipe. Apart from the fan, it hardly uses any other equipment, so it does not lead to increased fuel consumption.

How Long Can a New Unopened Battery Be Stored?

New unopened batteries can generally be stored for one or two years. Here are the details: 1. New Battery Maintenance: New unopened batteries can typically be stored for one or two years, but they need to be charged every 3 months or half a year, as the battery will naturally discharge even when not in use. 2. Battery Storage: Batteries should be stored in a well-ventilated and dry place. They are sensitive to cold and should be kept in a warm environment with temperatures between 5-40 degrees Celsius. Avoid storing them near damp or heat-generating equipment. Additional Information on Battery Storage: 1. Avoid Storing with Electrolyte: When storing, try to avoid keeping the battery with electrolyte. If stored with electrolyte, it needs to be charged periodically, and the liquid level and density should be adjusted. Ensure the battery is fully charged before storage. 2. Battery Charging Time: Battery charging times are generally long, averaging around 8 hours. It's important to monitor the charging time carefully. If the charging current is high, the battery may charge quickly, but continuing to charge can lead to overcharging, causing water loss and overheating, which reduces the battery's lifespan.

What needs to be done for the third car maintenance?

Regular items for the third car maintenance include changing the engine oil, oil filter, air filter, cabin air filter, spark plugs, etc. Some brand manufacturers may add additional maintenance items. The reason for this depends on the service life of car parts. Some parts have a shorter service life and are prone to getting dirty, so they need to be replaced frequently. Other parts have a longer service life and a longer replacement cycle. The specific details are as follows: 1. Engine oil change: Under the harsh conditions of high temperature and high pressure in the engine, the shelf life of engine oil is greatly shortened, its performance significantly declines, and it loses its protective effect on the engine. The replacement cycle for mineral oil is about 5,000 kilometers; for synthetic oil, it's about 10,000 kilometers. 2. Oil filter replacement: To ensure the cleanliness of the oil circuit, the engine is equipped with an oil filter in the lubrication system to prevent impurities from mixing into the oil, causing oxidation and producing sludge that can block the oil circuit. The replacement cycle for the oil filter is the same as for the engine oil, and it must be replaced simultaneously with the oil. 3. Air filter replacement: The air filter prevents dust and particles from being sucked into the engine during the intake process. If the filter is not cleaned for a long time, it can lead to dust being sucked into the engine, causing abnormal wear on the cylinder walls. The air filter should be cleaned every 5,000 kilometers by blowing it clean with an air gun and replaced every 10,000 kilometers.
