Rear Glass Stored in Glass Storage Pocket Standing outside of the vehicle, place one hand against the crossbar so the Midgate does not fall forward unexpectedly. Turn the Midgate handle clockwise and pull the Midgate toward you. If you lower the Midgate with the rear glass in the stored position, you will notice that the entire crossbar (the bar with the release handle) will lower with the Midgate. This is completely normal; however, since the crossbar lowers with the Midgate, it will be heavier. As you lower the Midgate in this configuration be ready for the extra weight and be careful not to let the Midgate fall out of your hands as you lower it. 2-20
