To open or close the sunroof (manual slide feature), pull or push the sunroof control lever backward or forward to the first detent position.
Pulling the control lever downward also closes the sunroof.
To open or close the sunroof completely even when the lever is released (auto slide feature), pull or push the sunroof control lever backward or forward to the second detent position. The sunroof will slide all the way open or closed. To stop the sunroof sliding at any point, pull or push the sunroof control lever momentarily in the opposite direction of sunroof movement.
Automatic reversal
If an object or part of the body is detected while the sunroof is closing automatically, it will reverse direction, and then stop.
The auto reverse function does not work if a small obstacle is between the sliding glass and the sunroof sash. You should always check that all passengers and objects are away from the sunroof before closing it.
