illuminate and/or flash when
operator assistance is required. In
addition, engine performance
becomes increasingly limited above
Level 1.
At Levels 1 and 2, two courses of
action may be taken by the operator
to facilitate filter regeneration:
1. The vehicle may be driven on the highway at highway speeds,
2. The operator may perform a parked regeneration by following the
steps in Parked regeneration procedure.
At Level 3, performing a parked regeneration is the only available course
of action (short of professional servicing) available to the operator for
regenerating the filter. At Level 4, professional servicing is the only way
to regenerate the filter.
Parked regeneration procedure
WARNING: When performing the parked regeneration
procedure, make certain the vehicle is safely off roadway, and
the exhaust system is away from people, or any flammable materials,
vapors, or structures. Engine speed may increase during parked
regeneration.
Note: Parked regeneration is only available when the DPF lamp on the
instrument cluster is illuminated (solid or flashing).
1. Bring the vehicle to a complete stop on level ground and safely off the
road with the exhaust system away from people, flammable materials,
vapors or structures. Ford recommends that you perform a walk-around
to check before commencing parked regeneration.
2. If your vehicle is equipped with an automatic transmission and a
steering column shift lever, place transmission in P (Park). Otherwise,
place the transmission in N (Neutral).
3. Remove feet from the accelerator pedal and clutch pedal (if
equipped).
4. Set the parking brake.
5. Within 5 seconds of setting the parking brake, remove foot from
the service brake pedal.
