Diesel Particulate Filter; Switching Off The Engine - Ford RANGER 2012 Owner's Manual

Starting and Stopping the Engine

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 the high temperatures
reached during regeneration and is normal.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.
Note: Under certain conditions, the engine
cooling fan may continue to run for several
minutes after you switch your vehicle off.
This could happen in low ambient
temperatures and independent of the
engine coolant temperature, for example
short journeys or low coolant temperature.
The diesel particulate filter on your vehicle
requires periodic regeneration to maintain
its correct function. Your vehicle will carry
out this process automatically.

If your journeys meet one of the following
conditions:
• You drive only short distances.
• You frequently switch the ignition on
and off.
• Your journeys contain a high level of
acceleration and deceleration.
You must carry out occasional trips with
the following conditions to assist the
regeneration process:
• Drive your vehicle in more favorable
conditions, which you will find at higher
vehicle speeds in normal driving, on a
main road or freeway for a minimum
of 20 minutes. This drive may include
short stops that will not affect the
regeneration process.
• Avoid prolonged idling and always
observe speed limits and road
conditions.
• Do not switch the ignition off.
• Select a suitable gear to ideally
maintain engine speed between 1500
and 3000 RPM.

SWITCHING OFF THE ENGINE

Vehicles With a Turbocharger
WARNING
Do not switch the engine off when it
is running at high speed. If you do, the
turbocharger will continue running
after the engine oil pressure has dropped
to zero. This will lead to premature
turbocharger bearing wear.
Release the accelerator pedal. Wait until
the engine has reached idle speed and then
switch it off.
