CAUTION! (Continued)
• DO NOT OVERFILL. DEF will freeze below 12
degrees F (-11 degrees C). The DEF system is
designed to work in temperatures below the DEF
freezing point, however, if the tank is overfilled
and freezes, the system could be damaged.
• When DEF is spilled, clean the area immediately
with water or use an absorbent material to soak up
and spills on the ground.
• Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it can
result in severe damage to your engine, including
but not limited to failure of the fuel pump and
injectors.
3. Stop filling the DEF tank immediately when any of the
following happen: DEF stops flowing from the fill
bottle into the DEF tank, DEF splashes out the filler
neck, or a DEF pump nozzle automatically shuts off.
4. Reinstall cap onto DEF tank.
Filling the DEF tank in cold climates
Since DEF will begin to freeze at 12°F (-11°C), your
vehicle is equipped with an automatic DEF heating
system. This allows the DEF injection system to operate
properly at temperatures below 12°F (-11°C). If your
vehicle is not in operation for an extended period of time
with temperatures below 12°F (-11°C), the DEF in the
tank may freeze. If the tank is overfilled and freezes, it
could be damaged. Therefore, do not overfill the DEF
tank.
