Diesel Particulate Filter - Ford F-150 2018 Owner's Manual

Typical Diesel Exhaust Fluid Usage
When Using the Power Take Off (PTO)
Continuous PTO use—Minimal PTO use
0–7,800 mi (0–12,550 km)
Contaminated Diesel Exhaust
Fluid or Inoperative Selective
Catalytic Reduction System
Selective catalytic reduction systems are
sensitive to contamination of the diesel
exhaust fluid. Maintaining the purity of the
fluid is important to avoid system
malfunctions. If you remove or drain the
diesel exhaust fluid tank, do not use the
same fluid to refill the tank. The system
has a sensor to monitor fluid quality.
A warning lamp illuminates and
a message appears in the
information display if the system
E163176
becomes contaminated or inoperative.
Continued driving without replacing diesel
exhaust fluid or having the selective
catalytic reduction system repaired results
in the following actions as required by the
California Air Resources Board (CARB) and
U.S. Environmental Protection Agency
(EPA):
• Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.
• Further vehicle operation without
replacing contaminated diesel exhaust
fluid causes the engine to enter an
idle-only condition. This only occurs
upon vehicle refueling, vehicle idling in
park for 1 hour, or engine shutdown for
10 minutes or more and is indicated by
a message in the information display
indicating required actions to resume
normal operation.

Note: For vehicle speed limiting or idle-only
condition, normal vehicle operation resumes
when you repair the contaminated system.
To service a contaminated or inoperative
system, see an authorized dealer.

DIESEL PARTICULATE FILTER

The filter forms part of the emissions
reduction system on your vehicle. It filters
harmful diesel particulates (soot) from the
exhaust gas.
Regeneration
WARNING
Do not park or idle your vehicle over
dry leaves, dry grass or other
combustible materials. The
regeneration process creates very high
exhaust gas temperatures and the exhaust
will radiate a considerable amount of heat
during and after regeneration and after you
have switched the engine off. This is a
potential fire hazard.
Note: Avoid running out of fuel.
Note: During regeneration at low speed or
engine idle, you may smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to high temperatures
reached during regeneration and is normal.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.
The diesel particulate filter on your vehicle
requires periodic regeneration to maintain
its correct function. Your vehicle will carry
out this process automatically.
