• DEF is subject to freezing at the lowest temperatures. For example, DEF may
freeze at temperatures at or below 12° F (-11° C). The system has been
designed to operate in this environment.
NOTE: When working with DEF, it is important to know that:
• Any containers or parts that come into contact with DEF must be DEF
compatible (plastic or stainless steel). Copper, brass, aluminum, iron or
non-stainless steel should be avoided as they are subject to corrosion by DEF.
• If DEF is spilled, it should be wiped up completely.
Adding Diesel Exhaust Fluid
• The DEF gauge (located on the EVIC display) will display the level of DEF
remaining in the tank.
• When the DEF gauge reads 75%, add approximately 2.5 gallons (9.5 Liters) to
fill the DEF tank.
• When the DEF gauge reads 50%, add approximately 4 gallons (15 Liters) to fill
the DEF tank.
• When the DEF gauge reads 25%, add approximately 6 gallons (23 Liters) to fill
the DEF tank.
NOTE: Driving conditions (altitude, vehicle speed, load, etc.) will effect the
amount of DEF that is used in your vehicle.
DEF Fill Procedure
• Remove cap from DEF tank (located on drivers side of the vehicle).
• Insert DEF container into DEF tank.
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.
• Reinstall cap onto DEF tank.
• Refer to your Owner's Manual on the DVD for further details.
