SUN ROOF - Description

Description

The sunroof offers extra ventilation for the interior compartment and ensures a rapid air exchange, if required, thus increasing passenger comfort.

This is an extensive glass roof, the front part of which can move and the rear part of which is fixed.

An interior blind, which is rolled in the actual roof lining, can be operated manually and guarantees protection against the rays of the sun.

The system is operated by a switch, located near the front courtesy light, which controls a motor with two different operating modes: press one end of the switch to raise the roof in 'compass' fashion, and press the other end of the switch to slide the roof open and so pull the blind.

The movement of the roof is controlled either manually or automatically, in accordance with the following logic:

• if the button is pressed for between 60 and 300 milliseconds, the operation is manual: the roof only moves when the button is pressed;
• if the button is pressed for over 300 milliseconds, the operation is instead automatic: even if the relevant button is released, the roof continues to close/open as far as the end of travel or until the anti-crush safety system intervenes, if applicable;
• a subsequent press on the button during movement of the roof locks it in its current position;
• if the button is pressed for less than 60 milliseconds, it is ignored (it is considered to have been knocked accidentally).

The electronic control unit for the roof also include a special anti-crush safety function: whilst the roof is closing, the movement is interrupted or reversed briefly if an obstacle is detected by a Hall effect sensor located on the motor.

The windows are automatically closed by a specific prolonged command (over 3 seconds) sent by the remote control button, if the ignition is off;

The remote control receiver aerial is connected directly to the Body Computer which contains the electronics for the actual receiver.
