The one the first time you turn it on in the settings:
Autosteer feature is currently in Beta:
Autosteer is for use on highways that have a centre divider and clear lane markings, or where there is a car directly ahead to follow. It should not be used on other kinds of roads or where the highway has very sharp turns or lane markings that are absent, faded, or ambiguous. Similar to the autopilot function in airplanes, you need to maintain control and responsibility for your vehicle while enjoying the convenience of Autosteer.
Do you want to enable Autosteer while it is in Beta? (No/Yes)
The one each time you engage it:
In 7.1 it appears to read "Always pay attention to the road, Be ready to take over at any time"
in 7.0 it says "Keep your hands on the wheel, be prepared to take over at any time"
