The switch for the fuel
door is on the instrument
panel, to the left of the
steering column.
If your fuel filler door release won't operate, there is a
manual release tab. The tab is located against the trim on
the driver's side of the vehicle, in the trunk.

The cap is behind a hinged door on the left side of your
vehicle. While refueling, hang the cap by the tether from
the pin on the filler door.
To remove the cap, turn it slowly to the left
(counterclockwise). The cap has a spring in it; if you let
go of the cap too soon, it will spring back to the right.
