Sunroof / Moonroof: Description and Operation






Sunroof Function

All moving functions of sunroof with glass panel can be performed with ignition switched on.

After the ignition is switched off, these functions are available until the driver or passenger door is opened.

The opening of glass panel for sliding and tilt position is pre-selected using the rotary switch.

On the rotary switch, there are markings for preset sliding and tilt positions of the glass panel.

Opening the sunroof in the so-called comfort position prevents most driving noise which may occur when open completely.

The sunroof with glass panel is equipped with a closing force limit. Glass panel runs in the opposite direction if it runs into an obstruction during the closing or opening procedure from the tilt or sliding position.
