Manual Operation of Power Liftgate To change the liftgate to manual operation, press the switch on the center console to the OFF position. 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. It is not recommended that you drive with the liftgate open, however, if you must drive with the liftgate open, the liftgate should be set to manual operation by pressing the OFF switch on the center console. 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. With the power liftgate disabled and all of the doors unlocked, the 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 to lower the liftgate and close. The liftgate latch will power close. Always close the liftgate before driving. If the battery is properly connected with adequate voltage, the switch is not disabled, and the liftgate still will not function, your vehicle should be taken to a dealer/retailer for service. 2-17
