To open the sunroof manually, move the switch backward to the first position. Pressing the switch to position two results in a so-called express opening, which manoeuvres the sunroof into comfort position automatically (approximately 75% open). The same can be done when closing at position one, closing manually and at position two, express closing i.e. when the sunroof closes completely. To open to tilt position, press the switch upwards. To close, press the switch forwards to position two. The sunroof closes automatically from tilt position.
Auto-opening means that if the sunroof opens, the hatch opens enough so that you can see that it has opened. This is so you will notice that the hatch is open.
Auto-closing means that if the sunroof is closed manually but a slight gap remains, the hatch will close the rest of the distance automatically.
Since the hatch can be closed with express closing, it is equipped with pinch protection. This means that if an object comes between the hatch and the edge of the sunroof, closing is stopped and the window is opened 125 mm, whereby the object will be released. Pinch protection is also available for express closing of tilt position in which case the window opens to full tilt position.
During manual opening and express opening, the sunroof always stops in comfort position, or approximately 75% open. An additional press of the switch towards the rear is required to open the sunroof completely.
Pinch protection can be disengaged due to snow, ice or other obstructions that prevent the sunroof from closing. This can be done by pressing the driver's door child safety button with the ignition on while pressing the roof console switch forwards.
Comfort opening or closing can be done with the remote control; press and hold the opening or closing button until the sunroof is in the comfort position or completely closed.
If the sunroof cannot be closed in the normal manner, emergency closing is available. Press the pin in the centre groove of the motor shaft with a screwdriver and turn it clockwise for emergency closing. The sunroof closes with a forward motion. Turning the motor shaft anti-clockwise will open the sunroof.
The control module with motor is located in the front edge of the sunroof assembly. It receives +30 to pin 5 from fuse 18 in the REC. The motor's power ground is with pin 6 via the REC in grounding point G29. The control module with logic is grounded with pin 2 via the REC in grounding point G3. Control module pin 1 is used for bus communication via the REC. The control module has self-diagnostics with its own diagnostic trouble codes.
All logic for the various opening positions is contained in the control module.
The control module sends out the following on the I-bus: Sunroof movement, power consumption, open or closed position.
The control module receives the following on the I-bus: Request for comfort opening, request for comfort closing.
Replacement of a control module requires a thorough check of the hatch position in the sunroof assembly when a new unit is delivered with the motor in closed position. See Electric motor for the sunroof .
