"top off"

On the screen of a gas pump, a statement appears,

"Avoid spills and protect the environment. Do not top off."

So what does it mean? Thank you.

It means that when the pump shuts off automatically (because the sensor detects fuel backing up in the filler pipe) you should not squeeze the trigger again to pump more fuel.
