Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The Webasto Hollandia 700 sunroof is available in both glass panel (40 series) and steel panel (20 series) models, designed to enhance the driving experience with a range of pre-programmed and programmable features. This service manual provides comprehensive instructions for both models, ensuring proper operation and maintenance.

Function Description

The Hollandia 700 sunroof is equipped with a Sunroof Control Unit (SCU) that manages its various functions. The primary function is to provide an open-air driving experience, allowing the panel to slide open or tilt for ventilation. The SCU integrates several intelligent features to enhance user convenience and safety.

Usage Features

The Hollandia 700 offers a user-friendly experience with several pre-programmed functions:

• Soft Touch Operation: This feature allows for effortless control of the sunroof. A quick press of the switch will initiate the opening or closing of the sunroof panel. The movement can be stopped at any desired position by pressing the switch again, offering precise control over the panel's travel.

• Variable Tilt Position: For optimal ventilation, the sunroof panel can be adjusted to four different tilt positions. By continuously pressing the switch, the panel will cycle through these positions, allowing the user to release the switch at the desired tilt angle. This provides flexibility in managing airflow and comfort within the vehicle.

• Jamming Protection (Safety Feature): Safety is a key aspect of the Hollandia 700. The jamming protection system is active when the sunroof is closing, whether through soft-touch control or the ignition auto-close mode. If the panel encounters an obstacle during closure, it will immediately reverse its direction and open again. The sunroof will then repeatedly attempt to close until the obstruction is removed, ensuring the safety of occupants and preventing damage to the mechanism.

• Auto-Close Function: This convenient feature automatically closes the sunroof when the vehicle's ignition is turned off. A beep will sound to alert the driver that the auto-close function is about to activate. After a three-second delay, the sunroof will close, indicated by two beeps. If the driver wishes to prevent the sunroof from closing, a brief press of the switch during the three-second interval will stop the operation. The sunroof can also be closed manually when the ignition is off. Upon switching the ignition back on, the sunroof resumes normal operation.

• One-Way Closing: To ensure a perfect fit and seal, the Hollandia 700 always closes the panel from above. This mechanism guarantees a flush fit of the panel with the roof, contributing to reduced wind noise and improved aesthetics.

In addition to these pre-programmed features, the Hollandia 700 also offers programmable options:

• Comfort Position: This feature allows users to program two additional stopping positions within the sunroof's sliding range. These custom positions can be accessed by operating buttons 1 or 2 on the control panel.
  • Programming the Comfort Position:
    1. Position the panel at the desired preset location.
    2. Press and hold button 1 for approximately 3 seconds until a beep is heard. This saves the first comfort position.
    3. Move the panel to the second desired preset location.
    4. Press and hold button 2 for approximately 3 seconds until a beep is heard. This saves the second comfort position.
  • When opening the sunroof using comfort button 1 or 2, the panel will stop at the corresponding preset position. Operating the switch again will fully open the sunroof.

Maintenance Features

The service manual outlines various repair and maintenance procedures to ensure the longevity and optimal performance of the Hollandia 700 sunroof. These include:

• Troubleshooting Electrical Failures: A detailed electrical troubleshooting guide (see point 2.2.6) and electric scheme (figure 2.1) are provided to help diagnose and resolve electrical issues. This includes testing electrical components like the fuse, wire harness connections to the battery and control panel, and the motor.

• Motor Replacement: Instructions are given for replacing the motor (46), which involves accessing the motor cover (48), disconnecting the motor wire from the SCU (51), and remounting the new motor. Proper operation in both directions is to be inspected after replacement.

• Sunroof Control Unit (SCU) Replacement: The manual details the process of replacing the SCU (51), including disconnecting wires, removing the unit, and installing a new one.

  • SCU Calibration: After replacing the SCU or when it's first connected to power, calibration is essential. This involves defining the maximum vent position by opening the panel to its mechanical stop while continuously controlling the switch. Once stored, all electrical features become available. To complete calibration, the panel must be moved to the fully open position using soft-touch operation.

• Drive Cable Replacement: This is a more involved procedure, requiring the removal of various components such as covers (7), panel (1, 100), drain channel (3), wind deflector (3), sunshade (5) or trim tray (103), and ventilation tray (105) and adjustment bracket (106). The process includes placing the mechanism in a closed position, accessing the motor cover, disconnecting the motor and SCU, removing the gearwheel housing (44) and gearwheel (40), and carefully removing and installing the new drive cable (25). Proper greasing and seating of the cable's copper head are crucial.

• Timing the Drive Cables: This procedure is critical for correct sunroof operation. It involves fully venting and then closing the panel, accessing the motor and SCU, removing the gearwheel housing and gearwheel, and then pushing the LH/RH mechanisms to a closed position. A pin or pointed awl is inserted into 2.5 mm brass holes to stop the mechanism at the desired location, ensuring correct timing. The new gearwheel is then mounted, ensuring it's centered and correctly oriented with its splines.

• Seal Replacement (Hollandia 700 - 20 Series and 40 Series): Instructions are provided for replacing the panel seal (101 for steel, 2 for glass). This involves removing the panel, cleaning debris, applying silicone to the retaining channel, installing the new seal with firm pressure for flushness, trimming excess, and using super glue to close the seam neatly. Drying time for mastic is also specified.

• Retraction Mechanism Replacement: This involves retracting the panel, removing the wind deflector (4), and then removing and replacing the retraction mechanism (33) by unscrewing (31, 32) and sliding it forward.

• Guide Rail Mechanism Replacement: This extensive repair requires removing numerous components including mechanism covers (7), panel (1,100), drain channel (3,102), wind deflector (4), and sunshade (5). The locator (13), retraction mechanism (33), and rail screw (9) are also removed. The rail is slid sideways to unlock, lifted, and the drive cable is carefully removed. The new mechanism is then installed, ensuring the cable is properly seated, and liquid butyl is applied as indicated.

• Blocking Catch Replacement: This involves removing mechanism covers (7) and panel (1) (or trim tray (103), drain channel (102), ventilation tray, and panel (100) for the 20 series), fully retracting and then tilting the mechanism, removing the locator (13), lifting out the blocking catch (26), cleaning debris, and installing a new blocking catch.

• Seal Adjustment (Hollandia 700 - 20 Series and 40 Series): This procedure addresses gaps between the seal and the EPDM trim ring or flanged metal circumference. It involves readjusting the panel, marking areas of insufficient contact with a grease pencil, removing the panel, inserting a spacer (vinyl tube with 3 mm outer diameter) inside the rubber seal in the marked areas, gluing the spacer, and then remounting and adjusting the panel.

Throughout these maintenance procedures, emphasis is placed on inspecting for proper electrical and mechanical functioning, ensuring all screws are tightened, and following specific instructions for each model series.
