How to test drive through the express train?

The debugging process is as follows:

1, get into the cab, adjust the comfortable position, and carefully observe all positions in the car, especially the blind spots of A-pillar, B-pillar and C-pillar.

2. Turn the steering wheel to neutral and feel the weight of the steering wheel. When the car is driving, hit the steering wheel left and right several times to feel the accuracy of the steering wheel.

3. Increase the test drive speed to more than 60 kilometers per hour, close the windows and music, and experience it carefully.

4. Observe the tachometer, and pay attention to it from the start to the re-acceleration, because the tachometer represents the quality of the engine, for example, the speed is fast and the speed is low, indicating that the engine is OK.

5. During the test drive, be sure to find a corner and turn at a speed of about 35km/h, so as to preliminarily predict the grip of the original tire.
