• 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. Extra care should be taken when filling
with portable containers to avoid overfilling. Note the level of the DEF gauge in
your instrument cluster. On pickup applications, you may safely add a maximum
of 2 gallons (7.5 liters) of DEF from portable containers when your DEF gauge is
reading ½ full.
DEF Fill Procedure
• Remove cap from DEF tank (located
behind the fuel door on drivers side of
the vehicle).
• Insert DEF container or fill nozzle into
DEF fill location and fill DEF tank.
• Reinstall cap onto DEF tank.
Refer to your Owner's Manual on the DVD
for further details.
CAUTION!
• To avoid DEF spillage and overfilling, do not “top off” the DEF tank after filling.
• When DEF is spilled, clean the area immediately with water or a mild solvent.
• 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.
