Tailgate You can open the tailgate by pulling up on the handle while pulling the tailgate down. When you put the tailgate back up, be sure it latches securely. Follow these stepsif you want to remove the tailgate: 1. Raise the tailgate slightly. Remove both retaining cables. To remove each cable, turn it so the end faces the front. Then, push forward so the larger part of the hole is over the bolt. Pull the end over the bolt. 3. With the tailgate halfway down, pull the tailgate toward you at the left side and then move the tailgate to the left to release the right side. Reverse the procedure to reinstall. Make sure the tailgate is secure. 2-9
