GMC Terrain: Manual Operation of Power Liftgate
To change the liftgate to manual operation, turn the mode switch to the OFF position.

To open the liftgate, press the touch pad on the handle on the outside of the liftgate, and lift the gate open. To close the liftgate, use the pull cup to lower the liftgate and close. With the power liftgate disabled, the liftgate electric latch will still power latch once contact is made with the striker. Always close the liftgate before driving.
