Sunroof / Moonroof: Description and Operation

Roof Opening Panel

The roof opening panel system consists of the following components:

- Air deflector

- Front sliding glass panel

- Front sliding glass panel motor

- Power shade assembly (sunshade)

- Power shade motor

- Roof opening panel concertina blinds

- Roof opening panel drain trough

- Rear fixed glass panel

- Roof opening panel frame assembly

- Roof opening panel frame drain hoses

- Roof opening panel switch assembly

The roof opening panel assembly is equipped with a power shade, fixed glass panel and a sliding glass panel. The sliding glass panel and power shade are equipped with one-touch open and one-touch close (with obstacle detection) features. One-touch operation can be stopped at any time by pressing the roof opening panel switch a second time.

Power Shade Operation

To open the power shade, press and release the shade control switch. When the power shade is in the fully CLOSED position and the shade control switch is pressed, the power shade will automatically open and stop at the front glass panel. Pressing the shade control switch a second time will allow the power shade to open past the rear glass panel (full open position). To close the power shade, pull and release the shade control switch. When the power shade is in the fully OPEN position and the shade control switch is pulled, the power shade will close and stop at the rear glass panel. Pulling and releasing the shade control switch a second time will allow the power shade to the front glass panel (full CLOSED position). With the sliding glass panel in the fully OPEN position, the power shade is disabled to prevent wind damage.

Bounce-Back (Power Shade)

The power shade has a bounce-back feature. When an obstacle has been detected as the power shade is closing, the power shade will automatically reverse direction and open to a predetermined position.

NOTE: If the power shade is in the CLOSED position and a sliding glass control switch is activated, the power shade will perform a one-touch open operation automatically which will then be followed by the sliding glass operation that was requested.

Sliding Glass Panel Operation

To open the roof opening panel, press and release the slide control switch. The roof opening panel will open automatically. The roof opening panel movement can be stopped at any time by pressing the switch again. To close the roof opening panel, pull and release the slide or tilt control switch. The roof opening panel will close automatically. The roof opening panel movement can be stopped at any time by activating the slide or tilt control switch in either direction. To vent the roof opening panel, the roof opening panel must first be in the fully CLOSED position. Press and release the tilt control switch. The roof opening panel will move to the VENT position automatically. The roof opening panel can be closed by pulling either the tilt or slide control switch.

Bounce-Back (Sliding Glass)

The roof opening panel has a bounce-back feature. If an obstacle has been detected in the roof opening panel as the sliding glass is closing, the roof opening panel will automatically open and stop at a predetermined position.

Security Override

To override a bounce-back condition (to overcome the resistance of ice on the roof opening panel seal for example), within 2 seconds of a bounce-back event, pull and hold the slide or tilt control switch. The glass will operate in manual mode with bounce-back detection turned off until the switch is released.

Global Open/Close (if equipped)

NOTE: The global open feature may be enabled/disabled via scan tool or in some cases modified by the customer following a procedure listed in the vehicle Owner's Literature. For a complete list of available programmable parameters, refer to Information Bus.

The Smart Junction Box (SJB) sends a signal on the global open/close circuit to the roof opening panel motor to move the sliding glass panel to the CLOSED or VENT position as well as open and close both front door and rear door windows based on a signal received from the Remote Keyless Entry (RKE) transmitter. If the accessory delay relay is active, the global open feature will not operate. For information about the accessory delay relay, refer to Windows and Glass.
