What is the button at the end of the turn signal do
The owners manual would have that type of information, you really should go through it and familiarize yourself with your new vehicle.
Probably the windshield washer but do as Toms says and read the manual.
In our Lincoln MKZ that button turns on and off the lane keeping warning system.
