New cars can absolutely be driven on the highway during the break-in period, as long as other operational guidelines are followed. There is no need to worry about highway driving causing any harm to the new car. Most new cars undergo "cold break-in" before leaving the factory, where the engine is mounted on a specialized machine and run-in using an electric motor. During this process, most burrs on the parts are smoothed out. Additional information: The current maximum speed limit on highways in China is 120 km/h, which is easily achievable for most cars. However, it is important to note that the key restriction during the break-in period is the engine RPM. Generally, when the speed reaches 120 km/h, the RPM should not exceed 3,000. Experienced drivers will notice that even without reaching 3,000 RPM, the vehicle speed can already meet the maximum highway speed limit in China.

Is it illegal if one headlight is broken?

Having a broken headlight poses certain safety hazards. During daytime, drivers may primarily receive a warning. However, at night, it can easily affect the driving safety of other vehicles and may result in a fine. Below is relevant information about headlights: 1. Regulations: According to Article 21 of the Road Traffic Safety Law, before driving a motor vehicle on the road, the driver must carefully inspect the vehicle's safety technical performance; it is prohibited to drive a motor vehicle with incomplete safety facilities or components that do not meet technical standards and pose safety hazards. Otherwise, in accordance with Article 58, Clause 17 of the Road Traffic Safety Regulations, driving a motor vehicle with incomplete safety facilities or components that do not meet technical standards and pose safety hazards may result in a warning or a fine. 2. Headlights: Headlights have two modes: high beam and low beam. Use low beam on urban roads with streetlights, and switch to high beam on roads without streetlights or highways. When meeting another vehicle, switch from high beam to low beam.

What is the fuel consumption of the Mercedes-Benz GLK300?

The fuel consumption of the Mercedes-Benz GLK300 ranges from 7.8L to 11.3L. The variation in fuel consumption is primarily due to different driving habits, which can affect the car's fuel efficiency. It's worth noting that the GLK300 was an imported model prior to the 2011 version, and domestic production began with the 2012 model. Here is more information about the Mercedes-Benz GLK300: 1. In terms of exterior design: The car adopts a unique design concept, with minimal differences between the imported and domestically produced models. The front fascia retains the brand's signature design, including the family-style front grille. 2. From the side view: There are distinctions between the domestic and imported versions. The side of the car features a Grand-Edition badge, indicating that the initial domestic production of the GLK would not include the updated imported version at the same time.

What is the difference between P system and N system?

The differences between P system and N system are as follows: 1. Different television standards represented: (1) P system: Records 25 frames per second, sometimes also referred to as the 625-line, 25 frames per second, interlaced scanning, PAL color-encoded television system. The PAL system has a resolution of 720*576, approximately 400,000 pixels. (2) N system: Records 30 frames per second, it belongs to the simultaneous system, with a frame rate of 29.97 (simplified as 30) per second, 525 scanning lines, progressive scanning, an aspect ratio of 4:3, and a resolution of 720x480. 2. Different global application ranges: (1) P system: Its standard is mainly applied in China, the Middle East, and Europe. (2) N system: Its standard is mainly applied in Japan, the United States, Canada, Mexico, etc.

What is the difference between Mobil MT80 and Mobil 1?

The difference between Mobil MT80 and Mobil 1 is that Mobil MT80 has better durability and longevity, while Mobil 1 tends to be noisier. Below are the relevant details: 1. Considerations: When selecting engine oil, one should not be careless, as the quality of the oil directly affects the engine's lifespan. The key factors to consider are the quality grade and viscosity grade, and it is advisable to use low-viscosity oil. 2. Mobil 1: The noise issue with Mobil 1 could be due to factors beyond the oil's authenticity or quality. For instance, choosing an oil with too low viscosity may result in a thin oil film, leading to friction between components and noise. Another possibility is that the old oil was not completely drained during an oil change, causing the new oil to mix with the old oil, thereby reducing the oil's quality. Additionally, the noise could be due to prolonged use of the oil without timely replacement.

Reasons for Jetta's Jerky Start When Cold, Like Fuel Starvation?

Reasons for Jetta's jerky start and fuel starvation: 1. Low engine temperature: Especially during cold starts in winter, the temperature inside the engine is insufficient, and both fuel and lubricant temperatures are low. Therefore, more fuel should be injected during cold starts to meet power requirements. Poor fuel atomization at low temperatures leads to decreased ignition energy, affecting power output and causing the car to shake. 2. Carbon deposits in the engine and intake tract: Carbon deposits can absorb an appropriate amount of fuel, causing the ECU to make incorrect judgments. For example, if the computer controls the injection of 100 units of air-fuel mixture, but only 90 units actually enter the cylinder, with 10 units being absorbed by carbon deposits, even if the remaining 90 units burn completely, the required power output still cannot be achieved. 3. Ignition system failure: Aging of the ignition system leads to weakened ignition energy, causing the ignition coil or spark plugs to fail to fire continuously or resulting in intermittent ignition. This discontinuous ignition prevents smooth and continuous power output, leading to the jerky acceleration phenomenon.

How long should you wait to release the brake when the car shakes during hill start?

Release the brake when the car shakes for about five minutes during hill start. Here are the relevant details: 1. On the slope: The car is braked by the handbrake and will not roll. When starting, turn on the left turn signal, honk the horn, and check the rearview mirror to ensure safety. 2. Press the clutch pedal: Shift into first gear, gently lift the clutch to enter the semi-engaged state. The vehicle has already started, and at this point, even if the handbrake is released, the car will not roll back. Therefore, the handbrake should be released as soon as possible, and the throttle should be applied slowly. When the car is moving smoothly, the clutch pedal should be fully lifted to allow the clutch to engage completely, transferring the engine's power entirely to the driveshaft to drive the vehicle forward. The shorter the time in the semi-engaged state, the less damage to the clutch friction plates.
