What warning signs do you need at the scene of automatic car washing machine in gas station?

In addition to the steps of automatic car washing, warning signs will also write some disclaimers.

It means that the car was brought in for cleaning by your own choice. Whether it is because of your improper operation or machine failure, it has nothing to do with this gas station.

Car washing at gas stations is basically fully automatic. You just drive in and wait for the car wash, but this kind of car wash can't clean the car, and there is still a big difference between machine car wash and manual car wash. Might as well drive to the car wash shop and wash the car inside and out.
