Changing from 15-inch to 16-inch wheels on the original car will not pass the annual inspection. Reasons for failing the annual inspection: Any modification to the original car parts without approval will result in failing the annual inspection. The car must be restored to its original condition to pass. Benefits of changing from 15-inch to 16-inch wheels: The appearance will be significantly improved. Larger wheels mean wider tires, which provide better grip, shorter braking distance, and improved braking performance. Drawbacks of changing from 15-inch to 16-inch wheels: The wider tires increase friction, leading to higher fuel consumption and a heavier steering wheel. Key points to note when modifying wheels: When modifying wheels, the aspect ratio of the tires must be reduced accordingly to minimize the difference in tire outer diameter compared to the original specifications. If the difference is too large, it will affect the accuracy of the speedometer. Therefore, when changing from 15-inch to 16-inch wheels, the tires must be replaced with specifications suitable for 16-inch wheels, and the aspect ratio must be reduced accordingly.

Why does the BAIC EU5 charge slowly after a system update?

This is because the new system reduces the charging current to ensure safety, effectively turning fast charging into slow charging. Here are some precautions regarding electric vehicle charging: 1. Master the correct charging time: Pure electric vehicles take longer to replenish energy. If you choose a home charging pile, it takes nearly 8 hours to fully charge, while a fast charging pile takes about 40 minutes to reach 80% charge. Develop the habit of charging frequently and avoid waiting until the battery is too low. 2. Avoid over-discharging the battery: Over-discharging can reduce its lifespan. Although the battery pack is designed with a protection system, frequently driving the car until the red light comes on will definitely affect the battery pack's lifespan.

What's the matter with the Infiniti key system malfunction?

It may be due to a dead battery or a damaged remote key. Here is some information about car keys: 1. Classification: Car keys are divided into two types, one without an anti-theft chip and the other with an anti-theft chip. Keys with anti-theft chips are commonly found in some low-end models, which don't even have a remote control, and are rarely seen nowadays. 2. Smart key: A smart key is equivalent to a small radio wave transmitter. The chip inside the key contains a unique ID code that matches the car. When the smart key emits a radio wave, it is received by the car. After confirmation by the car's anti-theft system control unit, the key is recognized, and then the door can be opened and the engine started.

What does 'Exam Appointment Application in Progress' mean?

Exam Appointment Application in Progress means you are in the queue for scheduling. Below are specific reasons for failed exam appointment attempts: 1. Low priority: When too many people are booking simultaneously, your priority ranking might be lower than others. There's no need to rush logging in for appointment as slots are allocated based on priority. Even if you apply early, unsuccessful booking may occur if others hold higher priority. For first-time subject 1 exam appointments, the scheduling order is determined by the initial driver's license application processing time; for subsequent exam appointments, the previous exam date serves as the sorting criterion. 2. System issues: Occasionally, excessive system load may prevent some candidates from securing appointments, requiring waiting for system recovery.
