How many hours per day do you usually practice for Subject 2 driving?

Subject 2 driving practice usually lasts 2-4 hours per day. The practice time for Subject 2 varies from person to person: Candidates practicing at different driving schools often receive varying amounts of practice time. Therefore, for the Subject 2 test, the daily practice time and the number of practice days are not fixed for each individual. The Subject 2 test requires candidates to master basic driving operation essentials and possess fundamental vehicle control abilities. You can take the Subject 2 test twice at the test site: For the Subject 2 test, if a candidate fails the first attempt, they can retake it once. Those who do not participate in the retest or fail the retest will have their current test terminated, and they must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of scheduled tests for Subject 2 and Subject 3 road driving skills tests must not exceed five times. If a candidate fails the fifth scheduled test, the results of other previously passed subjects will be invalidated.

What engine is in the ax7?

The engine in the ax7 was jointly developed by BMW and the PSA Group, and is manufactured by the Shenlong Xiangyang factory. The engine models for the ax7 are PSARFN10LH3X and PSA3FY10XP, with a maximum power of 140 kW, a maximum torque of 300 Nm, and a maximum horsepower of 190. For daily maintenance of the ax7's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. In small amounts, the sludge remains suspended in the oil, but in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

How to reset the tire pressure on a BMW 320?

The steps to reset the tire pressure on a BMW 320 are: 1. Use the up and down selection buttons on the light switch to select the tire pressure loss display icon; 2. Press the BC button briefly, then press and hold the BC button; 3. A checkmark will appear below the instrument cluster, and the initialization will be completed after driving at a constant speed for 3 kilometers. The reset can only be performed when the ignition is in position 2 or the engine is idling. The BMW 3 Series is a new generation of sedan products from the BMW Group, with a body weight of 1465 kg, an inline 4-cylinder gasoline engine, dimensions of 4734mm in length, 1811mm in width, and 1455mm in height, a wheelbase of 2920mm, a fuel tank capacity of 63 liters, and a top speed of 218 to 250 km/h.

Solutions for a Dead Battery and Unable to Start the Car on the Highway?

If your car runs out of battery and cannot start on the highway, you can try push-starting or using a portable emergency jump starter. Push-starting: Push-starting depends on the situation, as not all road conditions are suitable. Generally, if the front of the car is facing downhill, push-starting will be much easier and help the vehicle accelerate. On the other hand, push-starting uphill can be exhausting, and it's hard to achieve the necessary speed. When using this method, be cautious and avoid push-starting in areas with heavy traffic or pedestrians to prevent accidents after the car starts. Portable emergency jump starter: Using a car emergency jump starter is similar to using a power bank. Connect the battery clamps to the corresponding positive and negative terminals on the car battery, then turn on the power switch to activate the power supply. Next, start the stalled vehicle. It's important to remove the battery clamps from the battery as soon as the car starts to avoid any potential damage to the emergency battery itself.

Do I Need to Change to Antifreeze Engine Oil in Winter?

If the engine oil grade is below 5W, it is absolutely unnecessary to switch to winter oil. Conditions for changing engine oil: Generally, 0W and 5W grade oils are relatively more expensive. Some older or low-end models may come with 10W or 15W grade oil as standard, or some car owners might opt for higher-grade oil for convenience and cost-saving. In such cases, it is necessary to switch to a lower-grade oil in winter. Additionally, for larger vehicles, due to engine operating conditions and long-distance, prolonged usage, the oil grade used may differ from that of regular household vehicles, often requiring higher-grade oil. These vehicles also need to switch to lower-grade oil in winter. Precautions regarding engine oil: Engine oil itself is a blend of base oil and additives. Under normal circumstances, if you choose high-quality oil, there is no need to add any additional oil additives. Indiscriminate use of oil additives not only fails to protect the vehicle but may also cause chemical changes in the oil, leading to a decline in the oil's overall performance.

How often should the spark plugs of Geely Emgrand GL be replaced?

Geely Emgrand GL spark plugs should be replaced every 40,000 kilometers. Methods to determine if spark plugs are damaged: Remove the spark plugs and observe them. The condition of the spark plugs can be judged based on their appearance and color. Normal spark plugs have an insulator skirt and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, with an electrode gap between 0.8-0.9mm and no signs of electrode burn. If the spark plugs are covered with oil or deposits but are not damaged, they can continue to be used after cleaning off the oil and deposits. If the spark plugs are severely damaged, showing signs such as blistering at the top, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plugs with new ones. Additionally, if the spark plugs appear black as if smoked, it indicates that the wrong cold or hot type of spark plug was selected, the mixture is too rich, or there is oil leakage.
