To close the 60/40 side doors, close the rear door first. Then close the front door. Check to make sure that both doors are completely closed. The front side swing-out door has a check strap assembly in the door frame to keep the door from opening beyond 90 degrees. To open the door beyond 90 degrees, close the door partially, pull the check strap toward you and then open the door. When you close the door, the check strap will automatically re-engage. To open the rear portion of a 60/40 door from the outside, pull the handle on the side of the rear door and pull the door toward you. 113
