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 obstacle, the power liftgate operation can be used again.
If the liftgate encounters multiple obstacles on the same power cycle, the power function will deactivate.
After removing the obstacles, the liftgate will resume normal power operation.
The 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.
