When You Cannot Unlock the Fuel Fill Door
■What to Do When Unable to Unlock the Fuel Fill Door
If you cannot open the fuel fill door, use the following procedure. 1.Open the trunk and pull off the left inside
cover.
2. Pull the release lever towards you.

4.Add fuel very slowly.
u The automatic fuel tank vent valve does
not operate when the fuel fill door is
opened manually. Trying to add fuel too
rapidly when the vent valve is closed will
cause fuel vapors to be pushed out the
filler pipe and can cause a small amount
of liquid fuel to be spilled onto the
ground.

The automatic fuel tank ve nt does not operate when
using the manual fuel door release. Gradually release
pressure by slowly turning th e fuel fill cap to the left.
If you hear a release of fuel vapors, wait until it stops,
then continue to slowly remove the fuel fill cap.
The malfunction indicator lamp may come on when
driving after you have refueled by manually opening
the fuel fill door.
