Description And Operation: 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.

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 SWITCH, SUNROOF, DESCRIPTION AND OPERATION .

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.

The sunroof motor assemblies feature integrated electronics which provides the express open and close capabilities and also the obstacle detection system. The obstacle detection is active during express close operations. There are two methods of overriding the obstacle detection system:

1. Press and hold the sunroof or sunshade CLOSE switch. Obstacle detection is not active during manual (press & hold switch) operation of the sunroof or power sunshade.
2. If the sunroof or power sunshade auto-reverses three consecutive times during express (press & release switch) close operation, the sunroof will enter override mode. All switch commands will be in manual mode (one-touch express operation will be disabled) while the obstacle detection feature is in override mode. Sunroof or power sunshade must be fully closed in manual mode (press & hold switch) or vehicle ignition cycled off and back on to exit override mode.
