Obstacle Detection Features If the liftgate encounters an obstacle during a power open or close cycle, a warning chime will sound and the liftgate will automatically reverse direction to the full closed or open position. After removing the obstruction, the liftgate may be power opened or closed normally. If the liftgate encounters multiple obstacles on the same power cycle, the power function will deactivate, and the liftgate will switch to manual operation. The REAR ACCESS OPEN warning message in the Driver Information Center (DIC) will indicate that the liftgate is open. After removing the obstructions, manually open the liftgate to the full open position or close the liftgate to the fully closed and latched position. The liftgate will now resume normal power operation. Your vehicle has pinch sensors located on the side edges of the liftgate. If an object is caught between the liftgate and the body and presses against this sensor, the liftgate will reverse direction and open fully. The liftgate will remain open until it is activated again or closed manually. Manual Operation of Power Liftgate To change the liftgate to manual operation, toggle the switch on the overhead console to the "Disable" position indicated by a circle. With the power liftgate disabled and the door unlocked, the power liftgate can be manually opened and closed. To open the liftgate, press the touchpad on the handle on the outside of the liftgate, and lift the gate open. To close the liftgate, use the pull cup or pull strap to lower the liftgate and close. The liftgate latch will power cinch to closed position. Always close the liftgate before driving. If the RKE button or the power close button on the liftgate is pressed while power operation is disabled, the lights will flash three times, but the liftgate will not move. 129
