The ignition does not need to be on. The remote fuel
door release will work in all transaxle positions. The
trunk release lockout switch must be in OFF for the fuel
door to open.
The fuel door can be opened manually in case of an
electrical power failure.
To open the fuel door, press
the button located on the
driver's door trim near the
trunk release button.
NOTICE:
Prying on a locked fuel filler door could damage
it. Use the remote fuel door manual release
located in the trunk.
To do so, first open the
trunk. The release
mechanism is located on the
driver's side of the vehicle,
at the top of the trunk
compartment. Pull the tab
toward you to release the
fuel door.
