DIESEL PARTICULATE FILTER (DPF)
Diesel vehicles equipped with a particle filter
have more efficient emission control. The
particles in the exhaust gases are collected in
the filter during normal driving.
When a DPF message is displayed, the filter
requires a regeneration cy cle to clean itself.
This requires the engine to have reached
normal operating temp erature. Regeneration
takes place automatically at an interval of
approximately 300-900 km (190-560 miles)
depending on driving c onditions. Regeneration
normally takes 10-20 minutes and is
automatically requested by the engine control
module if the vehicle is driven steadily at
vehicle speeds between 40mph to 70mph. It is
possible that the rege neration process will
occur at lower vehicle speeds, but the events
may take a little longer at a 50 km/h (30mph)
average speed.
DRIVING SHORT DISTANCES OR IN
COLD WEATHER
If the vehicle is fre quently driven short
distances or in cold weather conditions then
the engine may not re ach normal operating
temperature. This means that regeneration of
the diesel particle filter does not take place and
the filter is not efficiently cleaned. When the
filter reaches a condition when a filter
regeneration is approp riate and the current
drive style is not appropriate, a warning
triangle on the instrument panel illuminates,
and the message DPF Full. See manual is
displayed on the instrument panel. This is not
indicating a fault conditi on with the vehicle and
no dealership support should be required. Start
regeneration of the filter by driving the vehicle,
preferably on a main road or motorway. The
vehicle should then be driven for approximately
20 minutes or more. When regeneration is complete the warning
text is cleared automatically.
Note:
A small increase in fuel consumption
may be noticed temporarily during
regeneration.
ARDUOUS DRIVING CONDITIONS
When a vehicle is operated in severe or
arduous conditions, more frequent attention
must be paid to servic ing requirements. Refer
to your Service Portfolio for details or contact
your Dealer/Authorised Repairer for advice.
SAFETY IN THE GARAGE
If the vehicle has been driven
recently, do not touch exhaust and
cooling system co mponents until the
engine has cooled.
Never leave the engine running in an
unventilated area.
Do not work beneath the vehicle with a
jack as the only means of support.
Keep your hands and clothing away
from drive belts, pulleys and fans.
Some fans may continue to operate
after the engine has stopped.
Remove metal wrist bands and
jewellery, before working in the
engine compartment.
Do not touch electrical leads or
components while the engine is
running, or with the starter switch
turned on.
Do not allow tools or metal parts of the
vehicle to make contact with the
battery leads or terminals.
