7. Remove the spout from the DEF container and install the cap back on
the bottle.
8. If the container is empty, discard the empty container and spout, or
recycle if possible. If there is some DEF left in the container, retain it
and the spout for later use. Store the spout to keep it clean.
9. Wipe away any DEF that has spilled on painted surfaces with water
and a damp cloth.
DEF Filling Station Nozzle Fill
Filling the DEF tank using a nozzle is similar to a normal fuel fill. The
nozzle shuts off automatically when the tank is full. Do not continue to
fill the tank as this may cause spillage and overfill the tank, which can
cause damage.
Filling the DEF Tank in Cold Climates
DEF freezes below 12°F (-11°C). If temperatures are at or below 12°F
(-11°C) for an extended period, and the DEF tank is full, and you are
not going to drive your vehicle, there is a risk that the tank could freeze,
causing damage. If low temperature conditions are expected, you should
keep your tank at least 50% full and make sure you add DEF on level
ground to prevent the fluid from freezing on an angle.
Contaminated DEF
SCR systems are sensitive to contamination of the DEF. USE ONLY
CERTIFIED DIESEL EXHAUST FLUID. If the system becomes
contaminated and you continue to drive your vehicle with contaminated
DEF, the following warnings result:
