Power Sunroof/Sunshade/Vent Switches
| Refer to COMPONENT INDEX . |
A switch cluster mounted in the overhead console controls sunroof operation. The sunroof switch cluster consists of three rocker switches (Sunroof Open/Close, Vent Open/Close, Sunshade Open/Close). Pressing the sunroof switch rearward commands the sunroof open, pressing the sunroof switch forward commands the sunroof closed. Pressing the vent switch rearward commands the sunroof to vent position, pressing the vent switch forward commands the sunroof closed. Pressing the sunshade switch rearward commands the sunshade open, pressing the sunshade switch forward commands the sunshade closed. If sunroof glass and sunshade are closed and one of the sunroof open/vent switches are pressed, the system will automatically retract the sunshade to behind the front glass opening (mid-point) before opening or venting the sunroof glass pane. Therefore the sunshade can never cover the movable glass pane opening unless the pane is in the fully closed position.
The sunroof receives the following hard-wired commands from the overhead console switches:
- Sunroof Open
- Sunroof Close
- Sunroof Vent
- Sunroof Switch Return
- Sunshade Open
- Sunshade Close
The sunroof has two modes of operation, manual and express:
- Manual Mode - The manual mode is active when the sunroof switch is pressed and held for a time greater than 0.8 seconds. When in manual mode the sunroof or sunshade operation will stop whenever the switch released.
- Express Mode - The express mode is active when the sunroof switch is pressed & released in a time less than 0.8 seconds. Express mode operation is a convenience feature that will automatically open or close the sunroof. Pressing any of the sunroof switches while express mode is active will immediately stop sunroof operation. The sunroof also provides an obstacle detection feature during express mode operation which automatically reverses the sunroof when it encounters an obstacle within the roof opening.
The sunroof has two programmed slide open stop positions; comfort stop position and full open position. The comfort stop position is approximately 114mm (4.5 inches) forward of the full open position and has been optimized to minimize wind buffeting in the interior when the vehicle is driven with sunroof open and all side windows closed. When opening the sunroof in either manual or express mode operation the sunroof will always stop at the comfort stop position. The sunroof open switch must be pressed again to continue to the full open position.
- Vent Position - The sunroof glass panel tilts upward 1 inch at the rear for the Vent position.
- Comfort Stop Position - Glass slides open approximately 440mm (17 inches) from the closed position.
- Full Open - Glass slides open approximately 554mm (22 inches) from the closed position.
- Closed Position - The sliding glass panel seals flush with the roof in the closed position to eliminate wind noise.
The chart describes the normal sunroof response to glass control switch inputs (for both Express and Manual operation) when the glass is in various positions.
| Initial Glass Position with Sunroof Response | ||||
|---|---|---|---|---|
| Switch Pressed | Glass Closed Position | Glass Comfort Stop Position | Glass Full Slide Open Position | Glass Vent Position |
| OPEN Switch | Sunshade opens to mid position (if closed) then glass slides open to comfort stop position | Glass slides open from comfort stop to full open position | No movement | Glass slides open from the vent position |
| VENT Switch | Sunshade opens to mid position (if closed) then glass cycles to vent position | Glass slides forward and stops at the vent position | Glass slides forward and stops at the vent position | No movement |
| CLOSE Switch | No movement | Glass slides to closed position | Glass slides to closed position | Glass cycles to the closed position |
For sunshade operation pressing the sunshade switch forward commands the sunshade closed. Pressing the sunshade switch rearward commands the sunshade open. When opening the sunshade it will automatically stop at mid-position, the sunshade open switch must be pressed again to continue to full open position. When attempting to close the sunshade and the glass is in the vented or open position the sunshade will stop at the mid-position. Pressing the sunshade close switch again will automatically close the glass; once the glass has fully closed the sunshade will automatically cycle to the closed position.

| Initial Shade Position with Sunroof Response | |||
|---|---|---|---|
| Switch Pressed | Shade Closed | Shade Half Open | Shade Full Open |
| OPEN Switch | Sunshade cycles to half open position | Sunshade cycles to full open position | No movement |
| CLOSE Switch | No movement | Glass first cycles to closed position (if glass open or vented) then sunshade cycles to closed position | - Sunshade cycles to half open position (if glass open or vented) - Sunshade cycles to full closed position (if glass closed) |
