Rear-Seat Pass Through
If the vehicle has the rear-seat pass through door, the trunk can be accessed through the rear seat.
This is useful when transporting long items.
To open the door, pull down the rear seat armrest. Then pull the lever all the way down to release the door.
To close the door, push it up and back into place. Then try to open the door without pulling up on the lever to make sure it is locked into place.
