Adding Diesel Exhaust Fluid
• The DEF gauge (located in the instrument cluster) will display the level of DEF
remaining in the tank.
NOTE:
Driving conditions (altitude, vehicle speed, load, etc.) will effect the amount of DEF
that is used in your vehicle.
NOTE:
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 of DEF
from portable containers when your DEF gauge is reading ½ full. On Chassis Cab
applications a maximum of 2 gallons may be added when the DEF gauge is reading
¾ full
DEF Fill Procedure
• Remove cap from DEF tank (located on drivers side of the vehicle).
• Insert DEF container into 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.
