Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very stable
product with a long shelf life. If DEF is kept in tempera-
tures 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 Electronic Vehicle Infor-
mation Center (EVIC) display) will display the level of
DEF remaining in the tank. Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
• When the DEF gauge reads 75%, add approximately
2 gallons (7.5 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.
