Dodge RAM 1500 User Manual page 191

NOTE:
• The DEF gauge may take up to five seconds to update after adding a gallon or
more of Diesel Exhaust Fluid (DEF) to the DEF tank. If you have a fault related
to the DEF system, the gauge may not update to the new level. See your
authorized dealer for service.
• The DEF gauge may also not immediately update after a refill if the temperature
of the DEF fluid is below 12F (-11C). The DEF line heater will possibly warm up
the DEF fluid and allow the gauge to update after a period of run time. Under
very cold conditions, it is possible that the gauge may not reflect the new fill
level for several drives.
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.
