Diesel particulate filter (DPF)*

E00619800069
The diesel particulate filter (DPF) is a device that
captures most of the particulate matter (PM) in the
exhaust emissions of the diesel engine. The DPF au-
tomatically burns away trapped PM during vehicle
operation. Under certain driving conditions, howev-
er, the DPF is not able to burn away all of the trap-
ped PM and, as a result, an excessive amount of
PM accumulates inside it.
WARNING
l The DPF reaches very high temperatures.
Do not park your vehicle in areas where
combustible materials such as dry grass
or leaves can come in contact with a hot
exhaust system since a fire could occur.
CAUTION
l Do not use any type of fuel or engine oil
that is not specified for your vehicle. Al-
so, do not use any moisture-removing
agent or other fuel additive. Such substan-
ces could have a detrimental effect on the
DPF.
Refer to "Fuel selection" on page 02 and
"Engine oil" on page 8-06.
NOTE
l To minimize the likelihood of excessive ac-
cumulation of PM, try to avoid driving for
long periods at low speeds and repeatedly
driving short distances.
DPF warning lamp
The DPF warning lamp comes on in the event of an
abnormality in the DPF system. Provided the DPF
system is working normally, the DPF warning
lamp comes on when the ignition switch is turned
to the "ON" position and goes off a few seconds later.
If the DPF warning lamp comes on dur-
ing vehicle operation
Steady illumination of the DPF warning lamp
shows that the DPF has not been able to burn away
all of the trapped PM and that, as a result, an exces-
sive amount of PM has accumulated inside it. To en-
able the DPF to burn away the PM, try to drive the
vehicle as follows:
l
th
With the gearshift lever in the 4 gear posi-
th
tion or 5 gear position, drive more than 15
minutes at a speed of at least 60 km/h
(37 mph) and an engine revolutions of at
least 2,000 rpm.
If the DPF warning lamp subsequently stays on, con-
tact your MITSUBISHI MOTORS Authorized Serv-
ice Point.
