Filling the Diesel Exhaust Fluid (DEF)
tank
WARNINGS
Make sure that Diesel Exhaust Fluid
(DEF) does not come into contact
with eyes, skin or clothing. Should
any DEF contact your eyes, flush them with
plenty of water and contact a physician.
Clean affected skin with soap and water.
If any DEF is swallowed, drink plenty of
water and contact a physician immediately Refill DEF in a well-ventilated area.
When opening the cap on the DEF
tank or bottle containing DEF,
ammonia vapors may escape. The vapors
can be irritating to skin, eyes and mucous
membranes. Inhaling ammonia vapors can
cause burning to the eyes, throat and nose
and cause coughing and watery eyes. Note:
Do not put DEF in the fuel tank. This
can cause engine damage not covered by
your vehicle ’s warranty.
Note: Immediately wipe away any DEF that
has spilled on painted surfaces with water
and a damp cloth to prevent damage to the
paint.
Your vehicle is equipped with a DEF tank
with a blue-capped filler port located next
to the diesel fuel fill inlet. The tank can be
filled using a nozzle at a DEF filling station
(similar to fuel fill) or using a DEF bottle
with a spout. We recommend Motorcraft®
DEF bottles since they are designed to be
spill proof and will stop the flow of DEF
when the tank is full. You can use other
aftermarket bottles, but they should have
a seal on the spout and an internal vent
tube to achieve best fill performance and
prevent overfilling. Overfilling your DEF
tank can cause damage to the tank. For
your DEF tank capacity. See Technical
Specifications (page 57). You can purchase Diesel Exhaust Fluid
(DEF) at an authorized dealer, most
highway truck stops or you can contact
roadside assistance for help in finding a
retailer that sells DEF. See the Customer
Assistance chapter in the Owner
’s Manual
for more information. In addition, there is
a government website locator for DEF at
the following web address to find the
nearest location to purchase DEF:
http://www.afdc.energy.gov/afdc/
locator/def. Use only DEF certified by the American
Petroleum Institute (API) such as
Motorcraft® DEF or equivalent meeting
Ford specification WSS-M99C130-A
and/or ISO 22241. Look for API certification
trademark shown here. Your vehicle
’s
warranty will not cover repairs resulting
from the use of non-certified diesel
exhaust fluid products.
Maintaining the purity of DEF is important
to avoid malfunctions in the selective
catalytic reduction system.
If you remove the DEF for tank repair, you
cannot use the same fluid to refill the tank.
You can no longer guarantee the purity of
the DEF.
To fill the DEF tank in cold climates, see
filling the Diesel Exhaust Fluid (DEF) tank
in cold climates later in this section or see
an authorized dealer.
