Reach inside the tailgate to lift the handle and open the tailgate. Remote Liftglass Release The REAR HATCH button, located to the right of the steering wheel on the instrument panel, allows you to release the liftglass from inside the vehicle. The tailgate can be opened without a key if the driver's door is unlocked. The liftglass will not release if the vehicle is in gear. To lock a power door lock system from the outside, insert the key into a lock button and turn clockwise. All doors, the tailgate and liftglass, or liftgate will lock. If your vehicle has an automatic transmission, your shift lever must be in PARK (P) or NEUTRAL (N) for the release to work. If you have a manual transmission, you must apply your parking brake or have the ignition off before you can open the liftglass. 2-13
