Roof Mechatronics
Basic sunroof actuator 

The actuator for the electric power sunroof is another component that contributes to convenience, providing a variety of roof configurations.
While electronic control opens, closes and tilts the sunroof, it also offers an extensive array of additional security and convenience functions.
Basic actuator
"One-touch" automatic operation: Open and close with a single touch of the button
Electronic control of end-position deactivation and intermediate stops
Enhanced convenience actuator 
Supplementary functions beyond those of the basic power units:
Preselection option for sunroof position
Soft Start and Stop minimizes noise by automatically reducing motor speed when approaching the end positions and at the base position
Roof position can be programmed to adapt to vehicle speed
