Sunroof / Moonroof: Description and Operation
SUNROOFDESCRIPTION
WARNING: Keep fingers and other body parts out of sunroof opening at all times.
The sunroof features a power sliding glass panel and a sunshade which can be manually positioned anywhere along its travel, rearward of glass panel front edge.
The sunroof is electrically operated from a switch located on the mini overhead console. To operate the sunroof the ignition switch must be in the On/Run position. The sunroof has both manual and Express Open modes of operation when opening. To open the sunroof in the Express Open mode, the switch is pressed rearward for less than 1 second. This causes the sunroof glass to automatically retract and stop at a position slightly forward of full open that reduces low speed wind buffeting. The sunroof can also be opened manually by pressing and holding the switch rearward. Once the switch is held reward for more than 1 second, the glass will retract in the manual mode. Releasing the switch at any time during travel will cause the sunroof to stop at the current position.
To close the sunroof from an open position, the switch must be pushed forward and held until the sunroof glass comes to a complete stop. Releasing the switch at any time in this mode will cause the sunroof to stop at the current position.
To vent the sunroof from the closed position, the switch is pushed forward and held. Releasing the switch at any time during travel will cause the sunroof to stop at the current vent position. To reach the fully vented position, continue to hold the switch forward until vent motion stops. To close the sunroof from the vent position, push and hold the switch rearward until the glass comes to a complete stop.
OPERATION
The power sunroof in the Grand Cherokee is controlled by the Body Control Module (BCM). After the ignition has been turned OFF, the power sunroof will remain operational for an additional 45 seconds. If the front doors are opened during this time, the BCM will remove power from the sunroof.
