ELECTRIC WINDOWS - SUNROOF
Electric sunroof: Initialisation
After any work has been carried out on the sunroof, or if there is a fault with the anti-pinch feature on the sunroof,
initialise the sunroof motor.
1) Read through the procedure in full before starting.
2) Switch on the + after ignition feed.
3) Move the sunroof control into the tilt position (control turned fully to the left).
4) Press and hold the central area of the control: the sunroof will move into the full tilt position without anti-pinch.
5) After hearing two clicking sounds (motor switching), press and hold the button for approximately 1 second,
release it and then press and hold it again until the roof opens and closes completely. It is normal for the sunroof
not to open immediately (delay of approximately 3 seconds).
6) Release the button.
The sunroof is operational again. The motor is initialised.
IMPORTANT
–If the procedure is interrupted during the cycle, start again from the beginning otherwise the sunroof will no
longer work.
–If there is too long a delay before the button is pressed for the second time during the procedure, start the
procedure again from the beginning.
