Sunroof, Dual Pane: Operation
The power sunroof system can only be operated when the vehicle ignition is set to ON/Run, Accessory or the Accessory Delay system is active. If the sunroof is in operation when the vehicle ignition is switched to START the sunroof will stop all motion. The sunroof switch will need to be pressed again to continue sunroof operation after the engine has started. If the sunroof is in operation when the vehicle ignition is switched to OFF all sunroof motion will stop immediately.
The front sunroof glass panel tilts upward at the rear for the ventilation position, or tilts down and slides rearward beneath the fixed glass panel for the open position. The sunroof module has two modes of operation; manual and express. Manual mode is active when the sunroof switch is pressed and held for a time >0.8 seconds. When in manual mode the sunroof or sunshade operation will stop whenever the switch released. Express mode operation is a convenience feature that will automatically open or close the sunroof when the switch is pressed & released in a time <0.8 seconds. The sunroof also provides an obstacle detection feature which automatically reverses the sunroof when it encounters an obstacle within the roof opening during express close operation. Refer to appropriate service information for options to override the obstacle detection system.
A combination push-button and rocker switch module mounted in the overhead console controls sunroof operation. The sunroof switch is a rocker design with a push button in the center of the two halves of the rocker. Pressing the rocker towards the front of the car commands the sunroof closed. Pressing the rocker towards the rear of the car commands the sunroof open. Pressing the center push button commands the front sunroof glass panel up into the vent position. If sunroof glass and sunshade are closed and one of the sunroof open/vent push buttons 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. For additional information. Refer to appropriate service information.

A rocker switch module mounted in the overhead console controls the power sunshade operation. Pressing the rocker towards the front of the car commands the sunshade closed. Pressing the rocker towards the rear of the car 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.
