NOTE:
•
Your vehicle is equipped with a DEF injection system.
You may occasionally hear an audible clicking noise
from under the vehicle at a stop. This is normal opera-
tion.
•
The DEF pump will run for a period of time after engine
shutdown to purge the DEF system. This is normal
operation and may be audible from under the vehicle.
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° and 90°F (-12° and 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
NOTE: Driving conditions (altitude, vehicle speed, load,
etc.) will effect the amount of DEF that is used by your
vehicle.
DEF Fill Procedure
NOTE: Refer to “Fluids And Lubricants” in “Technical
Specifications” for the correct fluid type.
