Switching Off The Engine; Vehicles With A Turbocharger - Ford Ranger Owner's Manual

Starting and Stopping the Engine
Regeneration
WARNING
Do not park or idle your vehicle over
dry leaves, dry grass or other
combustible materials. The DPF
regeneration process creates very high
exhaust gas temperatures and the exhaust
will radiate a considerable amount of heat
during and after DPF regeneration, and
after you have switched the engine off.
This is a potential fire hazard.
CAUTION
Avoid running out of fuel.
Unlike a normal filter which requires
periodic replacement, the DPF has been
designed to regenerate, or clean itself to
maintain operating efficiency. The
regeneration process takes place
automatically. However, some driving
conditions mean that you may need to
support the regeneration process.
If you drive only short distances or your
journeys contain frequent stopping and
starting, where there is increased
acceleration and deceleration, occasional
trips with the following conditions will
assist the regeneration process:
• Drive your vehicle at a constant speed,
preferably on a main road or motorway,
for up to 20 minutes.
• Avoid prolonged idling and always
observe speed limits and road
conditions.
• Do not switch off the ignition.
• Use a lower gear than normal to
maintain a higher engine speed during
this journey, where appropriate.

SWITCHING OFF THE ENGINE

Vehicles with a turbocharger

CAUTION
Do not switch the engine off when it
is running at high speed or
immediately after heavy towing. 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.
