Audi's on-demand four-wheel drive and full-time four-wheel drive differ in the following aspects: 1. Different concepts: On-demand four-wheel drive means the four-wheel drive system is activated when necessary, while operating as a two-wheel drive system under other conditions; full-time four-wheel drive is always in a four-wheel drive state. 2. Different applicable conditions: Vehicles with on-demand four-wheel drive are easy to operate and widely used in urban SUV models; full-time four-wheel drive is applied in off-road desert conditions. The full-time four-wheel drive system enhances wheel mechanical grip and driving stability. Audi's sedan lineup includes models such as the A4L, A6, A3, A7, and A8L. The Audi A8L is a full-size luxury sedan, competing in the same segment as the Mercedes S-Class and BMW 7 Series. The Audi A8L is equipped with Audi's full-time four-wheel drive system and features two engine options: a low-power version of the 3.0-liter turbocharged engine and a high-power version of the 3.0-liter turbocharged engine.

What type of fire extinguisher is used for vehicles?

Vehicle fire extinguishers use dry powder or water-based types, and their storage environment temperature should be within the range of -10 to 45 degrees Celsius. The placement location should be kept dry and ventilated to prevent the fire extinguisher from becoming damp and corroding. Fire extinguishers are divided into: 1. Aerosol fire extinguishers; 2. Dry powder fire extinguishers; 3. Ultra-fine dry powder fire extinguishers; 4. Carbon dioxide fire extinguishers; 5. Water-based fire extinguishers. The method of using a fire extinguisher is: 1. Bring the fire extinguisher to a location near the fire and stand on the upwind side of the fire; 2. Pull out the safety pin; 3. Hold the spray nozzle firmly with one hand; 4. Squeeze the handle tightly with the other hand; 5. Aim the nozzle at the base of the flames and sweep.

What to Do When the Tire Pressure Monitor Alarms?

The solutions for a tire pressure monitor alarm are: 1. Check if the tire has been punctured by a nail; 2. If the tire is low on air, promptly replenish the tire pressure. The functions of the tire pressure monitor are: 1. It will promptly alarm when the tire is punctured, causing rapid or slow air leakage; 2. It will alert to prevent a tire blowout when tire looseness leads to uneven friction, causing the tire temperature to reach 70 degrees Celsius; 3. It will alarm when the tire pressure is below the vehicle's set limit due to prolonged lack of inflation, preventing low pressure from causing a temperature rise and subsequent tire blowout. The method to reset the tire pressure monitor is: 1. Ensure the vehicle's tire pressure is within the normal range; 2. Park the vehicle on a level surface and turn off the engine; 3. Power on the vehicle, press and hold the tire pressure monitor button, and after 5 seconds, release the button upon hearing an alarm sound to successfully reset.

What maintenance does a car with 40,000 kilometers need?

The main maintenance items for a car with 40,000 kilometers include the following: 1. Changing the engine oil and oil filter is a must. Due to the harsh conditions of high temperature and high pressure inside the engine, the shelf life of the oil is significantly shortened, and its performance greatly deteriorates. Over time, it can no longer protect the engine effectively. The oil filter is replaced simultaneously to prevent impurities from mixing with the oil, causing oxidation and producing sludge that can clog the oil passages. 2. The air filter should be replaced every 10,000 to 15,000 kilometers. 3. If the spark plugs have never been replaced before, they should be changed during the 40,000-kilometer maintenance.

Does a child count as overloading?

Having an extra child in the car counts as overloading. Here is the relevant information: 1. Traffic regulations regarding "overcrowding" do not specify the height, weight, or age of passengers, but only the "number." Therefore, in a car with a capacity of 5 people, an additional child (even an infant held in the arms of a parent) is considered overloading. 2. According to regulations, overloading a car will result in a penalty of 3 demerit points and a fine of 200 yuan. Moreover, if the number of overloaded passengers increases, the demerit points will also increase. In fact, the demerit points and fine are not the most important issues; the most critical concern is that overloading makes the interior space very cramped, affecting the driver's operation and significantly increasing the likelihood of traffic accidents.

Does a baby count as a passenger in a 5-seater car?

A baby does count as a passenger, and having an extra baby would be considered overloading. For regular family sedans, whether it's overloaded is not calculated by weight but by the "number of heads." Here are the specific details: 1. Three heads mean three people, even if one of them is a baby, it still counts as one spot. Private cars have a designated passenger capacity, which is indicated on the vehicle's registration certificate. Exceeding this number is considered overloading. Traffic regulations regarding "overcrowding" do not specify the height, weight, or age of passengers but only the "quantity." There is no distinction between adults and children. 2. The Ministry of Public Security's Order No. 123, Article 49 of the Road Traffic Safety Law, and Article 92 of the Road Traffic Safety Law all have clear regulations on overloading.

What happens if you fill a car that requires 95 octane with 98 octane fuel?

Occasionally filling a car that requires 95 octane with 98 octane fuel will not cause any issues, but doing so long-term can severely affect the normal operation of the engine, leading to knocking. In serious cases, it may reduce the engine's lifespan and increase maintenance costs. Precautions for refueling include: 1. Refuel in the morning or evening when temperatures are relatively lower, as the same volume of gasoline will have a higher mass; 2. When driving in the city, avoid filling the tank completely, as this increases the engine's load; 3. Do not wait until the car is completely out of fuel to refuel, as too little fuel can shorten the lifespan of the fuel pump; 4. Avoid refueling during thunderstorms, as the fuel nozzle might introduce stray currents into the fuel tank, increasing the movement of unstable gasoline molecules and posing fire or explosion risks; 5. Avoid mixing different grades of gasoline.
