To open either sliding door from outside the vehicle, pull the handle out and then pull the door toward the rear. If you slide the door all the way back, the door will rest in a detent position.

To move the door forward, you must first pull the door past the open detent position.

The driver's side sliding door is designed to open only a little if the fuel door is open. If this ever happens, do not try to force the sliding door. Just close the driver's side sliding door. Then when the fuel filler door is closed, the driver's side sliding door can be opened normally.
