To fill the DEF tank, see an authorized dealer or do the following (before
filling the DEF tank in cold climates, see Filling the DEF tank in cold
climates later in this section):
DEF Bottle Fill with Spout
The following procedure applies to Motorcraft DEF or similar DEF
bottles. For other brands or bottle types, see the instructions on the
bottle label.
1. Remove the cap from the DEF
container and twist the spout onto
the container until the locking tab
engages.
2. Open the DEF filler port on your
vehicle by turning the blue cap
counterclockwise a quarter-turn.
3. Lift and hold the DEF container,
without tipping, and insert the
spout, into the DEF filler port.
4. Lift and tip the container to let
DEF flow into the tank. Pour DEF
until the container is empty or DEF
flow stops. DEF can be seen flowing
through the spout, but does not
completely fill the spout while
flowing. Air is trapped in the spout
while DEF is flowing. When the
DEF tank is full, DEF completely
fills the spout and displaces the air
in the spout.
