Panorama roof systemThe Panorama roof system of your Porsche
consists of a total of four roof elements.
Roof element 1 is the draft deflector. This
adjusts itself according to the speed, and helps
protect from the disturbing effects of the wind
when the Panorama roof system is open,
especially at high speeds or from turbulent air
flow.
Both roof elements 2 and 3 can be moved by
activating the knob in the vehicle's longitudinal
direction. Roof element 3 can also be raised.
This allows the interior to be better ventilated.
Roof element 4 is a fixed glass element and
completes the Panorama roof system.
