To maintain the NOx absorbing function, the
fuel is supplied regularly to the catalyst while
driving, and the catalyst reduces NOx to
harmless N2 (nitrogen).
The bar graph of momentary fuel consump-
tion display (for vehicles with colour liquid
crystal display) and engine sound change
while NOx is being purged automatically by
the catalyst. These do not indicate a fault.
Diesel particulate filter
(DPF)*
E00619801297
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 automatically burns away
trapped PM during vehicle operation. Under
certain driving conditions, however, the DPF
is not able to burn away all of the trapped 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. Also, do
not use any moisture-removing agent or oth-
er fuel additive. Such substances could have
a detrimental effect on the DPF.
Refer to “Fuel selection” on page 2-02 and
“Engine oil” on page 10-05.
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.
l
The engine sounds slightly different from
usual while the DPF automatically burns
away trapped PM. The change in the engine
sound does not indicate a fault.
DPF warning lamp/warning
display
Warning lamp (mono-colour liquid crystal dis-
play)
Warning display (colour liquid crystal display)
The DPF warning lamp comes on or warning
display will appear in the event of an abnor-
mality in the DPF system.
If the DPF warning lamp/
warning display illuminates
during vehicle operation
Steady illumination of the DPF warning
lamp/warning display shows that the DPF has
not been able to burn away all of the trapped
PM and that, as a result, an excessive amount
of PM has accumulated inside it. To enable
the DPF to burn away the PM, try to drive the
vehicle as follows:
