OGAE14E1Starting and driving6Vehicles with M/T Vehicles with A/T

NOTElFor diesel-powered vehicles, if the tempera-
ture inside the engine compartment is high,
the cooling fans (A) will continue to operate for some time even if the engine is stopped.
Therefore, the operation sound of the cool-
ing fans may be heard even after the engine is stopped. This sound is normal and does
not indicate a malfunction.
After operating for a period of time, the cooling fans will stop automatically.
*: Front of the vehicle
Using the MIVEC engine*
The MIVEC engine automatically switches
its intake-valve control between a low-speed mode and a high-speed mode in accordancewith driving conditions for maximum engine
performance.
NOTEl To protect the engine, the high-speed mode
may not be selected while the engine coolanttemperature is low.Fuel injection amount learning
process (diesel-powered vehi- cles)
E00627900043
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.
Diesel particulate filter
(DPF)* E00619800245
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.
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.

Steady illumination of the DPF warning dis- play 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 ac- cumulated inside it. To enable the DPF toburn away the PM, try to drive the vehicle as
follows:
l With the bar graph of engine coolant
temperature display stabilized in roughly
the middle of the scale, drive for about 20 minutes at a speed of at least 40 km/h
(25 mph).
If the DPF warning display subsequently stays on, contact your MITSUBISHI
MOTORS Authorized Service Point.CAUTIONl You do not have to continuously drive ex-
actly as indicated above. Always strive to drive safely in accordance with road condi- tions.If the DPF warning display and

E00611200083CAUTIONlDo not run the engine at high speeds (for ex-
ample, by revving it or by accelerating rap-
idly) immediately after starting it.
l Do not stop the engine immediately after
high-speed or uphill driving. First allow the
engine to idle to give the turbocharger a
chance to cool down.Turbocharger
The turbocharger increases engine power by
pushing large amounts of air into the engine’s
cylinders. The finned parts inside the turbo- charger turn at extremely high speeds and aresubjected to extremely high temperatures.
They are lubricated and cooled by engine oil.
If the engine oil is not replaced at the speci- fied intervals, the bearings may seize or emit
abnormal noise.
