1-12 Keys, Doors and Windows Manual Operation of Power Liftgate To change the liftgate to manual operation, turn the mode switch to the OFF position. With the power liftgate disabled and all of the doors unlocked, the liftgate can be manually opened and closed. Manual operation of a liftgate that also has power operation requires more effort than with a standard manual liftgate. 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 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. If the RKE button is pressed while power operation is disabled, the turn signals flash and the liftgate will not move. The liftgate has an electric latch. If the battery is disconnected or has low voltage, the liftgate will not open. The liftgate will resume operation when the battery is reconnected and charged. Setting the Power Liftgate 3/4 Mode To change the liftgate stop position: 1. Turn the liftgate switch to the 3/4 mode position and power open the liftgate. 2. Stop the liftgate movement at the desired height by pressing any switch. 3. Press and hold the button on the liftgate adjacent to the latch until the turn signals flash and a beep sounds to indicate that the new setting is recorded. When power opened with the 3/4 mode selected, the liftgate stops at the new set position. There is a minimum that the power liftgate must already be open for the system to hold it open. The liftgate cannot be set to stop below that minimum.
