The sliding door lock will now work normally. Liftgate To unlock the liftgate from the outside, turn the key in the cylinder clockwise. To lock the liftgate using the key, turn the key counterclockwise. Open the liftgate using the handle above the license plate. Once slightly opened, the liftgate will rise by itself. Lamps in the rear of the vehicle will come on, illuminating the rear cargo area (see "Interior Lamps" in the Index). To close the liftgate, pull down on the handle, then firmly shut the liftgate. Don't drive with the liftgate open, even slightly. See "Engine Exhaust" in the Index. A light on your instrument panel will warn you if the liftgate is not completely closed (see "Door Ajar Warning Light" in the Index). NOTICE: Be sure there are no overhead obstructions, such as a garage door, before you open the liftgate. You could slam the liftgate into something and break the glass. 2-31
