Generally, the vehicle's failure to start is caused by issues with the brake switch or poor battery contact. You can first turn the key halfway to allow the car to perform a self-check and observe the prompts given by the onboard computer. If it's not an engine malfunction, it could be due to lack of fuel, fuel line issues, a dead battery, or short circuits in electronic components. In such extreme cases, it's advisable to visit a 4S shop for inspection as soon as possible. When the battery is dead, the one-key start function cannot operate normally, and the battery should be replaced proactively. If that doesn't work, seek after-sales service to diagnose the fault.

What are the items included in a major vehicle service?

Automobile major service generally requires replacing engine oil and oil filter, spark plugs, air filter element, cabin air filter, transmission fluid, brake fluid, and coolant; cleaning throttle valve and engine carbon deposits; conducting a comprehensive inspection of various vehicle components' conditions, such as checking for oil leaks, assessing aging and wear of rubber components like tires and bushings. Additional information about vehicle maintenance is as follows: 1. Vehicle maintenance involves systems including: engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, brake system, etc. 2. Adjust maintenance intervals based on conditions: If the local environment is harsh with poor road conditions, the maintenance interval should be appropriately shortened, especially for air filter elements and cabin air filters.

How to Repair a Broken Car Window?

Automotive glass cracks are generally repaired using specialized repair tools and repair fluid. The repair fluid is filled into the crack through the repair tool, solidifying to eliminate the gap, thereby achieving the purpose of repair. Here are some considerations: 1. It is important to note that if the glass develops cracks, those that can be repaired should be addressed as soon as possible, and those that require replacement should be replaced promptly. This is because, during driving, the windshield must withstand wind resistance and constant vibrations. Over time, small cracks can gradually extend, lengthen, and expand in area. At this point, glass that could have been repaired may only be replaceable. 2. Long cracks in automotive glass are difficult to repair. After all, the effectiveness of repairing large cracks is not ideal, often leaving noticeable marks. Moreover, the strength of the repaired windshield cannot be guaranteed, posing a risk of re-cracking and potential safety hazards. Therefore, it is recommended to replace the glass.

Which is Better: Hybrid or Plug-in Hybrid?

Plug-in hybrid is better. Plug-in hybrid vehicles are more fuel-efficient and can also benefit from national new energy subsidies. Below is a detailed comparison of the two: 1. Plug-in hybrid vehicles (PHEV, plug-in hybrid electric vehicle) are a necessary transition from new energy vehicles to pure electric models and represent one of the future trends in automotive development. Equipped with a battery pack and electric motor, their most notable feature is the presence of a charging port for external charging. Currently, these vehicles can typically travel about 50 kilometers in pure electric mode, which is sufficient for urban commuting. They have larger battery capacities, and the electric motor directly participates in driving, serving more than just an auxiliary role as in conventional hybrid vehicles. 2. Conventional hybrid vehicles have smaller battery capacities and can only recharge the battery through the normal operation of the engine. The battery's primary function is to start the vehicle, assist in acceleration, and so on. Beyond a certain speed, the engine takes over to propel the car. Since starting and rapid acceleration are the most fuel-intensive operations, the electric motor's intervention effectively addresses this issue, resulting in relatively low fuel consumption.
