NOTElWhen the engine is warm, the diesel preheat
indication lamp does not come on even if the
ignition key is placed in the “ON” position.
Start the engine by turning the ignition key
right to the “START” position.
7. Turn the ignition key to the “START”
position without depressing the accelera- tor pedal, and release it when the engine
starts.
Fuel injection amount learning
process (diesel-powered vehi-cles)
E00616000044
To keep exhaust emissions and engine noise low, the engine very occasionally performs a
learning process for the fuel injection
amount.
The engine sounds slightly different from
usual while the learning process is taking place. The change in the engine sound does
not indicate a fault.
NOx trap catalyst
(dieselpowered vehicles)* E00649200020
A NOx (nitrogen oxide) trap catalyst absorbs
the NOx contained in the exhaust gas of the diesel engine.
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 in the centre information display and en- gine sound change while NOx is being
purged automatically by the catalyst. These
do not indicate a fault.Diesel particulate filter
(DPF)* E00619800027
The diesel particulate filter (DPF) is a devicethat 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.
WARNINGl 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.CAUTIONl 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 10-04.NOTEl 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.
