DEF Fill Procedure
1. Remove cap from DEF tank (located behind the fuel door on drivers side of the
vehicle).
2. Insert DEF container or fill nozzle into
DEF fill location and fill DEF tank.
3. Reinstall cap onto DEF tank.
Refer to your Diesel Supplement on the
DVD for further details.
• 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.
