When the car is in season change maintenance, the passengers need to pay attention to the tire detection and maintenance, summer tires due to high temperature friction, wear and tear will be relatively large lead to cracks. Automatic transmission maintenance reminds you that cracks will also increase during your daily driving. Therefore, cyclists in autumn season maintenance should pay special attention to check whether there are cracks in the tire, careful detection of surface damage, see if there is abnormal wear and tear to ensure driving safety.

这时，车友可通过轮胎指示标志（磨损极限位置）或者深度计、游标卡尺等方法进行检测。据介绍，轮胎沟槽深度标记的极限尺寸为1.6mm.需要提醒的是，特别是新车主，在驾驶前要注意其轮胎极限位置的标记。一旦当轮胎磨损到极限位置时，就要及时更换轮胎。

At this time, the rider can be through the tire indication mark (wear limit position) or depth meter, vernier caliper and other methods to detect. According to the introduction, the limit size of the groove depth marking is 1.6mm. It should be reminded, especially for new owners, to pay attention to the mark of the tire limit position before driving. Once the tire is worn to the limit, it is necessary to change the tire in time.

除了要检查轮胎之外，换机油是车辆保养的重要组成部分，由于车辆的使用、环境的影响，以及一些材料随时间的变化，必须定期检查，及时发现以避免更大的损坏或者事故发生。在进行换季保养时，还要特别关注一下汽车机油的浓度问题。自动变速箱维修厂家提醒各位车友们在选择发动机油的时候，需要考虑到季节的变换问题。因为油品的黏度会随气温变化而变化，冬天黏度变高，夏天黏度变低。因此在比较炎热的地区和季节，尽量选择油品黏度稍高一点的机油。而在温度出现变换，天气寒冷时，可以使用黏度较低的机油。

In addition to checking tires, oil change is an important part of vehicle maintenance. Due to the use of vehicles, environmental impact, and changes in some materials over time, regular inspection must be carried out to avoid further damage or accidents. During seasonal maintenance, we should pay special attention to the concentration of motor oil. Automated transmission maintenance manufacturers remind you that when choosing engine oil, you need to consider the problem of seasonal change. Because the viscosity of oil will change with the change of temperature, the viscosity will increase in winter and the viscosity will decrease in summer. Therefore, in a relatively hot area and season, try to select a slightly higher oil viscosity. And when the temperature changes, when the weather is cold, you can use low viscosity oil.
