If the engine warning light is on, but there are no abnormal noises in the engine compartment, no other warning prompts on the dashboard, the vehicle's power is unaffected, and the transmission shifts gears normally, you can continue driving to the 4S shop for further diagnosis. Issues such as intake and exhaust systems may trigger the engine warning light, and each case should be analyzed individually. There are two scenarios for the engine warning light: 1. Yellow symbol light: Indicates there is a fault in the engine, but it does not affect normal operation; however, maintenance is required. 2. Red symbol light: Indicates a serious engine fault. Normally, immediate repair is necessary. In special circumstances, you may drive temporarily, but you must continuously monitor the engine's operating condition.

What are the reasons for the Buick Regal not responding when stepping on the accelerator?

Buick Regal not responding when stepping on the accelerator may be due to the following reasons: 1. Transmission failure: This is relatively easy to diagnose. If the accelerator pedal cannot be depressed, the engine speed may suddenly increase from 2000 RPM to 4000 RPM. This happens because the power is cut off, causing the engine to suddenly operate with zero load, leading to speed fluctuations. Generally, when there are issues with the engine, including problems with the transmission control system, the engine warning light will illuminate, and a fault code will be stored. In this case, use a diagnostic tool to read the fault code. 2. Clutch: It might be that the clutch is not released; simply releasing it should resolve the issue. 3. Handbrake: If the handbrake is not released, it can also affect the accelerator response.

How often should the transmission fluid be changed for the Mistra?

The transmission fluid for the Mistra should be changed every two years or 40,000 kilometers. Below is some information about transmission fluid changes: 1. Circulation machine method: This method achieves fully intelligent and equal-volume fluid replacement. The transmission fluid is changed while the vehicle is running, allowing the fluid to circulate internally and carry away contaminants inside the transmission. The replacement rate can exceed 90%. 2. Replacement capacity: Most vehicles require 6-10 liters of transmission fluid per change. The exact amount depends on the vehicle model and the replacement method used. Typically, during a transmission fluid change, the old fluid is drained by removing the transmission pan screw, and new fluid is added. However, this method only replaces about 70% of the old fluid with new fluid.

What should I pay attention to when driving with a newly obtained driver's license?

When driving with a newly obtained driver's license, there are several points to pay attention to: 1. You cannot drive alone on the highway during the probationary period. New drivers during the probationary period are not allowed to drive alone on the highway. If it is necessary to drive on the highway, there must be a driver with more than three years of driving experience accompanying you in the passenger seat, otherwise, you will be fined 200 yuan. 2. A "Probationary" sign must be affixed to the rear of the car during the probationary period. According to regulations, new drivers during the probationary period must affix a "Probationary" or "New Driver" sign to the rear of the car. If this is not done, a fine of 200 yuan will be imposed. 3. Accumulating 12 points on the driver's license during the probationary period will result in cancellation. If 12 points or more are accumulated, the driving qualification for the permitted vehicle type will be directly canceled, and you must reapply for learning and testing. 4. No need to replace the license after the probationary period ends. After the probationary period ends, there is no need to replace the license. You only need to wait until the 6-year validity period expires to undergo an annual review and apply for a new driver's license. Points deduction rules after the probationary period ends: If 1 to 11 points are deducted, after paying the fine, 12 points will be automatically restored in the next scoring cycle. If 12 points are deducted, you must study for 7 days and retake the subject one test. If 24 points are deducted, you must study for 7 days and retake the subject one and subject three tests.
