FORD F650 2013 12.G Owners Manual

SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM (DIESEL
ENGINE ONLY)
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of Maintaining the DEF Level
In order for the SCR system to operate properly, the DEF level must be
maintained. Generally, the DEF tank should be filled before the DEF
gauge in the instrument cluster reaches the first low level warning
(seeWarning messages and vehicle operations).
The engine control unit monitors the amount of fluid available in the
DEF tank. Failure to maintain an adequate amount of DEF in the system
generates warning messages that appear in the information display and,
unless the DEF tank is refilled, leads to a forced reduction of engine
operations.
Warning Messages and Vehicle Operations
The instrument cluster contains a DEF gauge and indicator lights to alert
you to any low DEF level conditions. The indicator lights illuminate if the
DEF gauge level drops below 0.5 gallons (1.9 liters) in the 5 gallon
(19.0 liters) DEF tank or 1 gallon (3.8 liters) in the 9 gallon (34.0 liters)
DEF tank.
Upon filling the DEF tank after a low level warning, normal operation
resumes when the vehicle is restarted.

Filling the DEF Tank
WARNING:Make sure that DEF does not come into contact
with eyes, skin or clothing. Should DEF contact your eyes, flush
them with plenty of water and contact a physician. Clean affected skin
with soap and water. If DEF is swallowed, drink plenty of water and
contact a physician immediately.
WARNING: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 or any other tank on the vehicle.
This can cause damage to components not covered by your vehicle’s
warranty.
Your vehicle is equipped with a DEF tank with a blue-capped filler port.
The 5 gallon (19.0L) DEF tank is located on the left side of the vehicle
under the cab. The 9 gallon (34.0L) DEF tank is located on the right
side of the vehicle behind the cab (Regular Cab and Super Cab) or under
the cab (Crew Cab). 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.
Motorcraft® brand DEF bottles are recommended. Other aftermarket
bottles can be used but should have a seal on the spout and an internal
vent tube to achieve best fill performance and prevent overfilling.
You can purchase DEF at your authorized dealer, most highway truck stops
or you can contact roadside assistance for help in finding a retailer that
sells DEF. See theCustomer Assistancechapter for more information.
Also, a government website locator is available for diesel exhaust fluid
supplies. The following web address can be used to find the nearest
location to purchase DEF: http://www.afdc.energy.gov/afdc/locator/def.
Use Motorcraft® DEF or equivalent meeting Ford
specification WSS-M2C130-A and/or ISO 22241. Use
only DEF certified by the American Petroleum
Institute. Look for this certification trademark. Repairs
resulting from the use of non-certified DEF products
may not be covered by your vehicle’s warranty.
Maintaining the purity of DEF is important to avoid malfunctions in the
SCR system.
If DEF is removed from the tank for any reason (such as repair work),
the same DEF must not be used to refill the tank as its purity is no
longer guaranteed.
To fill the DEF tank, see your authorized dealer or do the following
(before filling the DEF tank in cold climates, seeFilling the DEF tank
in cold climateslater in this section):
DEF Bottle Fill with Spout
The following procedure applies to Motorcraft® DEF or similar DEF
bottles. For other brands or bottle types, see the instructions on the
bottle label.

1. Remove the cap from the DEF
container and twist the spout onto
the container until the locking tab is
engaged.
2. Open the DEF filler port on the
vehicle by turning the blue cap
counterclockwise a
14-turn.
3. Lift and hold the DEF container,
without tipping, and insert the
spout, into the DEF filler port.
4. Lift and tip the container to let
DEF flow into the tank. Pour DEF
until the container is empty or DEF
flow stops. DEF can be seen flowing
through the spout, but does not
completely fill the spout while
flowing. Air is trapped in the spout
while DEF is flowing. When the
DEF tank is full, DEF completely
fills the spout and displaces the air
in the spout.
5. Once the spout is full with DEF (no more large air pockets), return
the container to the vertical position slightly below the DEF filler port
and let any DEF drain out of the spout. DO NOT try to continue to add
DEF to the tank by shaking or repositioning the container to induce flow.
This may cause spilling and overfill the tank. Overfilling the DEF tank
can cause damage to the tank.
6. Once the spout has drained, remove the spout from the DEF filler
port and install the blue cap on the DEF filler port by turning the cap
clockwise a
14-turn.

7. Remove the spout from the DEF container and install the cap back on
the bottle.
8. If the container is empty, discard the empty container and spout, or
recycle if possible. If there is some DEF left in the container, retain it
and the spout for later use. Store the spout to make sure it is kept clean.
9. Wipe away any DEF that has spilled on painted surfaces with water
and a damp cloth.
DEF Filling Station Nozzle Fill
Filling the DEF tank using a nozzle is similar to a normal fuel fill. The
nozzle shuts off automatically when the tank is full. Do not continue to
fill the tank as this may cause spillage and overfill the tank, which can
cause damage.
Filling the DEF Tank in Cold Climates
DEF freezes below 12°F (-11°C). If temperatures are at or below 12°F
(-11°C) for an extended period of time, and the DEF tank is full, and
you are not going to drive the vehicle, there is a risk that the tank could
freeze, causing damage. If low temperature conditions are expected, you
should keep your tank at least 50% full and make sure you add DEF on
level ground to prevent the fluid from freezing on an angle.
Contaminated DEF
SCR systems are sensitive to contamination of the DEF. USE ONLY
CERTIFIED DIESEL EXHAUST FLUID. If the system becomes
contaminated and the vehicle continues to be driven with contaminated
DEF, the following warnings result:
