WARNING: Stop refueling after the
fuel pump nozzle automatically shuts
off for the second time. Failure to follow
this will fill the expansion space in the
fuel tank and could lead to fuel
overflowing.
WARNING: Do not remove the fuel
pump nozzle from its fully inserted
position when refueling.
Use the following guidelines to avoid
electrostatic charge build-up when filling
an ungrounded fuel container:
Place approved fuel container on the
ground.
Do not fill a fuel container while it is in
the vehicle - including the cargo area.
Keep the fuel pump nozzle in contact
with the fuel container while filling.
Do not use a device that would hold
the fuel pump handle in the fill position.
Fuel Filler Cap
WARNING: The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler inlet, do not
refuel until the sound stops. Otherwise,
fuel may spray out, which could cause
serious personal injury.
Note: If you must replace the fuel filler cap,
replace it with a fuel filler cap designed for
your vehicle. The vehicle warranty may be
void for any damage to the fuel tank or fuel
system if you do not use the correct genuine
Ford or Motorcraft® fuel filler cap.
When fueling your vehicle:
1. Put your vehicle in park (P).
2. Switch the engine off.
3. Carefully turn the filler cap
counterclockwise until it spins off.
4. Pull to remove the cap from the fuel
filler pipe.
5. To install the cap, align the tabs on the
cap with the notches on the filler pipe.
6. Turn the filler cap clockwise until it
clicks at least once.
If the Check Fuel Cap light or a Check Fuel
Cap message appears in the instrument
cluster and stays on after you start the
engine, you may not have installed the fuel
filler properly.
If the fuel cap light remains on, at the next
opportunity, safely pull off of the road,
remove the fuel filler cap, align the cap
properly and reinstall it. The check fuel cap
light or Check fuel cap message may not
reset immediately. It may take several
driving cycles for the indicators to turn off.
A driving cycle consists of an engine
start-up, after four or more hours with the
engine off, followed by normal city and
highway driving.
REFUELING - DIESEL
WARNING: Read and follow all the
instructions on the pump island.
WARNING: Stay outside your
vehicle and do not leave the fuel pump
unattended when refueling your vehicle.
WARNING: Keep children away
from the fuel pump. Never let children
pump fuel.
WARNING: Wait at least five
seconds before removing the fuel pump
nozzle to allow any residual fuel to drain
into the fuel tank.
