OPERATING INSTRUCTIONS
All HOLLANDIA 700 models are standard equipped with a Sunroof Control Unit (SCU) in which many
features and operating options are programmed or can be programmed.
Pre-programmed functions:
•Soft touch
By quickly pressing the switch the sunroof will open or close (depending on the position of the
panel). Movement of the panel can be stopped by quickly pressing the switch again.
•Variable tilt position
The panel can be closed from tilt in four steps by continuously pressing the switch and releasing in
the desired position.
•Jamming protection (Safety Feature)
The jamming protection becomes active when the sunroof is closed either by soft-touch control or in
ignition auto-close mode. Should the panel encounter an obstacle while closing, it immediately
opens again. The sunroof will continuously try to close until the obstacle has been removed.
•Auto-close function
When turning off your vehicle’s ignition, the sunroof will beep to remind you that the auto-close
function will be activated. After three seconds the sunroof will close automatically which will be
indicated by two beeps. Should you require the sunroof to stop, briefly press the switch. You can
also prevent the panel from closing by pressing the switch during the three seconds interval. You
can still close the sunroof when the ignition is off. When you switch the ignition on, the sunroof opens
and closes in the normal manner.
•One-way closing
This feature always closes the panel from above, assuring a flush fit of the panel.

OPERATING INSRTUCTIONS

Programmable operation:
•Comfort position
With this feature you are able to program two additional stopping positions of the panel in the sliding range of
the sunroof. The panel will stop at the positions programmed when operating button 1 or 2.
PROGRAMMING THE COMFORT POSITION:
1. Place the panel in the desired preset position
2. Push and hold the 1 button for about 3 seconds until you hear a beep.
3. Place the panel in the second desired preset position.
4. Push and hold the 2 button for about 3 seconds until you hear a beep.
On opening the sunroof with the 1or 2comfort button the panel will stop in the preset position. Operating the
switch again will open the sunroof completely.

1.3.REPAIR ADVICE FOR RATTLING NOISE
PROBLEM POSSIBLE CAUSE SOLUTION
Drain channel rattles. Check if insulation tape is
applied between drain channel
and mechanism.
Add insulation tape.
Steel panel ventilation tray
rattling.
1. Curvature of front ventilation
tray incorrect.
2. Insufficient contact between
rail and ventilation tray tumbling
mechanism.
3. Wires insufficiently secured.
1. Manual adjust the curvature of
the ventilation tray.

screws.
1.4. REPAIR ADVICE FOR WIND NOISE
PROBLEM POSSIBLE CAUSE SOLUTION
Excessive wind noise when the
panel is in the closed position.

ring.
2. Blocking catch broken
1. Re-adjust the panel. (see
installation manual 5.3)
2. Replace blocking catch,
see 3.9
Whistling sound when panel is
placed in the tilt position.
Vinyl headliner material wrapped
around sunshade too thin,
creating large wind channel
between mechanism rail and
side of sunshade.
Place insulating tape along
either outboard edge of
sunshade to close channel.
See installation manual 4.1.6
Steel panel vented emitting
whistling sound.
Vinyl headliner material wrapped
around trim tray too thin,
creating large wind channel
between mechanism rail and
side of trim-tray
Place insulating tape along
either outboard edge of trim tray
to close channel. See installation
manual 4.1.6
