Manual Operation of Power Liftgate To change the liftgate to manual operation, press the switch on the overhead console to the OFF position. 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 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. 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. 2-18 Power Assist Steps Your vehicle may have power assist steps. The power assist steps automatically extend from beneath the vehicle on the side in which the door has been opened. Once the door is closed, the assist steps automatically move back under the vehicle after a brief delay. The vehicle must not be moving for the assist steps to extend or retract. The switch used to disable the power assist steps is located on the center console below the climate control system. The assist steps cannot be disabled in the extended position.
