Mercury 1996 Sable Manual page 291

The fuel system may be under
pressure. If the fuel cap is venting
vapor or if you hear a hissing sound,
wait until it stops before completely
removing the cap. Otherwise, fuel
may spray out and injure you or
others.
2. Make sure that you pump unleaded fuel and
put the nozzle all the way inside the fuel
filler pipe.
NOTE: To help reduce early nozzle shutoffs
and fuel spillage, park your vehicle so
that the fuel filler door is not
downhill. Do not tilt or turn the nozzle
upside down when filling. Avoid
excessively fast fuel dispensing rates
(over 10 gallons [38 liters] per minute).
3. If you spill any fuel on the body of your
vehicle, clean it off immediately. The fuel
may dull or soften the paint if you do not
wash it off.
4. To replace the fuel cap, align the tabs on the
cap with the notches on the filler pipe. Turn
it clockwise until it stops.
5. Push the fuel door closed.
If the Service Engine Soon warning light comes
on and stays on when you start the engine, the
fuel cap may not be properly seated. Turn off
the engine, remove the fuel cap and replace it,
being careful to align the cap properly. For more
information, see Warning lights in the Index.
