5. Once the spout is full with DEF (no more large air pockets), return
the container to the vertical position slightly below the DEF filler port
and let any DEF drain out of the spout. DO NOT try to continue to add
DEF to the tank by shaking or repositioning the container to induce flow.
This may cause spilling and overfill the tank. Overfilling the DEF tank
can cause damage to the tank.
6. Once the spout has drained, remove the spout from the DEF filler
port and install the blue cap on the DEF filler port by turning the cap
clockwise a 1 ⁄ -turn.

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.
