LR3/Disco 3
Open (slide)
With the sunroof panel tilted, pushing the upper part of the rocker switch operates the sunroof motor to raise the sunroof
panel and retract it backwards. A single press (between 0.5 and 1 second) of the switch operates the motor so that the
panel automatically retracts to the fully open position. When the panel retracts, a wind deflector automatically raises at the
front of the sunroof aperture, which serves to reduce wind noise.
When the open function is requested, the cables pull in a rearward direction, driving the glass panel attachments to slide
the panel over the exterior roof skin.
With the sunroof panel half or fully open, pushing the lower part of the switch operates the motor to close the sunroof
panel. A single press (between 0.5 and 1 second) of the switch operates the motor so that the panel automatically closes
to the fully tilted position.
If only partial opening or closing is desired, pressing the switch momentarily (less than 0.5 seconds) in either direction will
stop the sunroof panel movement. When movement is desired in either direction, pressing the switch will operate the
motor to move the panel.
The sunroof has an 'anti-trap' function which prevents the sunroof panel from closing if an obstruction is sensed. When an
obstruction is sensed, the motor will automatically retract the panel by 200mm or as far as possible. When the obstruction
is removed, the panel can be closed by the normal method.
Battery Disconnection
If the battery has been disconnected, the one touch and anti-trap function will become inoperative. Pressing the lower part
of the sunroof switch for 20 seconds will start the sunroof's calibration routine. The sunroof will complete a full cycle in
order to re-learn the parameters required for one-touch open and close and the anti-trap function. The sunroof will still
have manual movement available until the sunroof is re-calibrated.
