Body - Interior & Exterior: Sunroof: 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 (unless Accessory Delay system is active).
The sunroof glass panel tilts upward at the rear for the vent position, or tilts down and slides rearward beneath the roof 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 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. Pressing any of the sunroof switches while express mode is active will immediately stop sunroof operation. 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. For options to override the obstacle detection system, refer to MOTOR, SUNROOF, STANDARD PROCEDURE .
Switches 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 sunroof glass panel up into the vent position. If sunroof glass and sunshade are closed and the sunroof open switch is pressed, the moving glass will automatically drag/slide the sunshade to the open position. When in the glass is in the open position it is not possible to close the sunshade; attempting to manually force the sunshade to the closed position while the glass in a slide open position may result in damage to the sunroof system.
The below chart describes the normal sunroof response to glass control switch inputs (for both Express and Manual operation) when the glass is in various positions.
