What documents are needed for the first maintenance of a new car?

Items required for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle registration certificate; vehicle purchase invoice. Take these to the designated first maintenance facility for the vehicle's initial service. Important note: Make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after a new car has been driven, with specific timing varying by vehicle, typically after driving 1,000 to 3,000 kilometers. The car must undergo its first maintenance promptly, neither early nor delayed. The completion of the first maintenance signifies the end of the car's break-in period, allowing it to be driven under standard load and normal speed as required by the vehicle. The timing for the first maintenance is calculated from the date of vehicle pickup. There are two benchmark values for the first maintenance: mileage and time. Whichever comes first serves as the standard. First maintenance tasks include: changing the engine oil and oil filter, cleaning the air filter, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and examining tires for damage or bulges. Required time: Approximately 2 hours to complete all tasks. The most crucial aspect of a new car's first maintenance is changing the engine oil and oil filter. When changing the oil, the oil filter must also be replaced. The choice of oil must refer to the "Vehicle Use and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not rinse the interior of the car body with water: Many people clean their cars during holidays, washing the body with water and wiping it with a cloth. It's important to note that the interior of the car body should not be directly washed with water. If the floor mats are dirty, use a vacuum cleaner or take them out, scrub with a brush and detergent, dry them, and then put them back. There are many vent holes under the rubber mats on the floor of the driver's compartment. Water entering these areas will not dry but will flow through the holes to the gearbox and other parts, causing erosion and corrosion. The best practice is to clean with a vacuum and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it is recommended to drain the antifreeze and add the same brand from the start. Since antifreeze brands differ, their chemical properties vary greatly. Various functional additives can corrode others. Different brands of antifreeze use different additives, so they should not be mixed to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function properly again. To prevent rust on wheel bolts and nuts, some apply lubricant, but this poses a safety risk. At high speeds, bolts and nuts can loosen or even fall out, leading to driving malfunctions. Do not press the accelerator when starting an EFI car: The starter of an EFI car differs from that of a regular car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring smooth starting.

What does 'driving a few yards' mean?

As a unit of speed, 1 yard is equal to 1 kilometer per hour. Converted to meters per second, it should be 0.2778 m/s. As a unit of length, 1 yard is equal to three feet, which is 0.9144 meters. In modern colloquial usage, 'yard' is often used as a unit of speed, typically for the speed of vehicles, especially cars. Origin: A speed of 40 yards is equal to 64 km/h. The common expression of speed in 'yards' originates from the speed unit 'mile.' One mile is equal to 1 mile per hour, which converts to approximately 1.6 kilometers per hour in the metric system. International Metric System: Internationally, the metric system is commonly used. For example, a speed of 100 yards is equal to 100 kilometers per hour. When British people say 100 miles, it equals 160 kilometers per hour. In reality, 'mile' refers to Mile (mile), where 1 mile = 1.6 kilometers. Therefore, strictly speaking, 40 miles equals 64 km/h.

Is Transmission Fluid Considered a Lubricating Oil?

Transmission fluid is not classified as a lubricating oil. Engine oil serves as the lubricant for the engine system, possessing properties such as oxidation resistance, wear resistance, and anti-corrosion. In contrast, transmission fluid is primarily designed to maintain the cleanliness of the gear system and extend the service life of internal transmission components. Due to the distinct structures and operating environments of transmissions and engines, transmission fluid cannot be used as engine oil, nor can engine oil be substituted for transmission fluid. Symptoms indicating the need for transmission fluid replacement include: vehicle shaking, gear shifting hesitation; the appearance of a transmission overheating warning on the dashboard; vehicle stalling; and unusual noises. The methods for replacing transmission fluid are as follows: Unscrew the drain plug at the bottom of the transmission to drain the old fluid before refilling. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it allows for the removal of debris from the bottom of the oil pan. Use a circulation machine to replace automatic transmission fluid: Dynamic fluid replacement with an intelligent circulation machine can filter and clean out sludge and debris inside the automatic transmission. Hazards of prolonged failure to replace transmission fluid include: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Impaired transmission operation, leading to damage of the transmission valve body.

Do motorcycles have batteries?

Motorcycles do have batteries. The motorcycle battery serves as an auxiliary power source, primarily storing current and assisting with startup. If a motorcycle lacks a battery, the electric start function would lose its effectiveness, making the battery quite important for motorcycle ignition. Precautions for battery replacement: Visually inspect the casing for cracks, corrosion, or signs of burning; Use a voltmeter to measure the voltage between the casing and ground, ensuring it does not exceed 20V, as higher voltages pose an electric shock risk; After installing a new battery, perform a test run using Mercedes-Benz specialized diagnostic equipment. Precautions for car battery maintenance: Avoid leaving the car parked in open-air parking lots for extended periods. If long-term parking is necessary, remove and take the battery with you to prevent freezing damage; Car batteries require regular charging. A battery left unused for long periods will gradually discharge on its own until it becomes unusable. Therefore, start the car periodically to recharge the battery.

Is a Waste Engine Considered Hazardous Waste?

An engine is not classified as hazardous waste. Engines fall under the category of solid waste. In terms of waste recycling, engines should be categorized as scrap metal within the classification of solid waste. TFSI: TFSI refers to a FSI engine equipped with a turbocharger (T), hence the abbreviation TFSI. This designation is commonly used in Audi series vehicles. In the Volkswagen series, engines with direct injection (I), turbocharging (T), and mechanical (S) twin charging are abbreviated as TSI. Types of Engines: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy. This includes internal combustion engines (reciprocating piston engines), external combustion engines (such as Stirling engines and steam engines), jet engines, electric motors, and more.

What are the tips for learning to ride an electric bike?

Tips for learning to ride an electric bike: Foot-dragging practice: Before riding, straighten the electric bike. After starting, keep both feet touching the ground and slide them along as support points. This enhances balance and provides stability in case of tipping, allowing timely correction of the bike's posture. Accelerating practice: Once stable with foot-dragging, quickly retract your feet onto the pedals. This movement should be swift because slower speeds make it harder to maintain force balance after placing your feet on the pedals. At higher speeds, the bike becomes more stable without wobbling, and you only need to steady the handlebars.
