Why is one side wide and the other narrow when reversing into the garage?

Turning the steering wheel too early when reversing into the right side of the garage will cause the wheels to be too close to the garage corner, or result in the left side being wide and the right side narrow after parking. Turning the steering wheel too early leads to a narrow right side and a wide left side. Below is relevant information about reversing into the garage: 1. Technique: Turn the steering wheel fully to the right when the mirrors align. During the first attempt to reverse into the garage, observe the position relationship between the left rearview mirror and the parking line. First, turn the steering wheel half a turn to the right and start moving. When the left rearview mirror covers the parking line, turn the steering wheel fully to the right; while reversing with the steering wheel fully turned to the right, watch the right rearview mirror. Observe the distance between the car body and the right front corner of the garage, keeping this distance at 30 cm. If it is too narrow, adjust the steering wheel. The standard width of the garage line is 15 cm, so in the rearview mirror, it should appear roughly the width of two garage lines. 2. Precautions: Generally, start in 1st gear and avoid shifting into the wrong gear. When controlling the speed, turning the steering wheel as quickly as possible is always better. When these two factors conflict, prioritize controlling the speed.

What are the contents of the vehicle year code reference table?

Here is an introduction to the contents related to the vehicle year code reference table: 1. Look at the tenth digit: The tenth digit of the Vehicle Identification Number (VIN) can be used to determine the production year of the vehicle.
