User guide

• The DEF injection system and SCR catalyst enable the achievement of diesel

emissions requirements; while maintaining outstanding fuel economy,

drivability, torque and power ratings.

NOTE: The DEF pump will run for a period of time after engine shutdown to purge

the DEF system. This is normal operation.

Diesel Exhaust Fluid Storage

• Diesel Exhaust Fluid (DEF) is considered a very stable product with a long

shelf life. If DEF is kept in temperatures between 10° to 90°F (-12° to 32°C), it

will last a minimum of one year.

• 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.
