engine MITSUBISHI ASX 2012 (in English) Repair Manual

NOTE
l If
the engine is cold, the diesel preheat indi-
cation lamp is on for a longer time.
l When the engine has not been started within
about 5 seconds after the diesel preheat indi-
cation lamp went out, return the ignition key
to the “LOCK” position. Then, turn the key
to the “ON” position to preheat the engine
again.
l When 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” posi- tion without depressing the accelerator pedal,
and release it when the engine starts.
NOTE l Minor noises may be heard on engine start-
up. These will disappear as the engine warms
up.
Using the MIVEC engine*
The MIVEC engine automatically switches its in-
take-valve control between a low-speed mode and
a high-speed mode in accordance with driving con-
ditions for maximum engine performance.
NOTE l To protect the engine, the high-speed mode
may not be selected while the engine coolant
temperature is low. Fuel injection amount learning proc-
ess (diesel-powered vehicles)
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 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 8-04.
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. Starting and driving

The engine sounds slightly different from usu-
al while the DPF automatically burns away
trapped PM. The change in the engine sound
does not indicate a fault.
DPF warning display Type 1 Type 2
The DPF warning display illuminates in the event
of an abnormality in the DPF system.
If the DPF warning display illumi-
nates during vehicle operation
Steady

illumination of the DPF warning display
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 With the bar graph of engine coolant temper-
ature 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. CAUTION
l
You
do not have to continuously drive ex-
actly as indicated above. Always strive to
drive safely in accordance with road con-
ditions.
If the DPF warning display and check
engine warning lamp illuminate at the
same time during vehicle operation Warning lamp Warning display type 1

Turbocharger operation*
E00611200083CAUTION
l
Do not run the engine at high speeds (for
example, by revving it or by accelerating
rapidly) 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 turbocharg-
er a chance to cool down. Turbocharger
The

turbocharger increases engine power by push-
ing large amounts of air into the engine’s cylinders.
The finned parts inside the turbocharger turn at ex-
tremely high speeds and are subjected to extremely
high temperatures. They are lubricated and cooled
by engine oil. If the engine oil is not replaced at the
specified intervals, the bearings may seize or emit
abnormal noise. 1- Air compressor

INVECS-III Sports Mode 6CVT
(Intelligent & Innovative Vehicle Electronic Control System III)* E00602100031
The
INVECS-III uses optimization and adaptation
functions to optimally match the gear ratio to driv-
ing and road conditions.
The CVT is capable of changing the gear ratio auto-
matically and steplessly to suit driving conditions
in all phases of vehicle operation. It therefore real-
izes smooth, shock-free operation and excellent
fuel efficiency. CAUTION
l
Automatic
downshifts may not take place
while the CVT fluid is still cool immedi-
ately after you start driving. To cause a
downshift, depress the brake pedal, man-
ually shift down when necessary.
Always strive to drive safely in accord-
ance with road conditions.
Selector lever operation E00602200221
The CVT selects an optimum gear ratio automati-
cally,

depending on the speed of the vehicle and
the position of the accelerator pedal. The selector lever (A) has 2 gates; the main gate
(B) and the manual gate (C).
While depressing the brake pedal,
move
the selector lever through the gate. Move the selector lever through the gate. WARNING
l Always
depress the brake pedal when
shifting the selector lever into the other
position from the “P” (PARK) or “N”
(NEUTRAL) position.
Never put your foot on the accelerator ped-
al while shifting the selector lever from
the “P” (PARK) or “N” (NEUTRAL) po-
sition.
NOTE l To

avoid erroneous operation, move the se-
lector lever firmly into each position and brief-
ly hold it there. Always check the position
shown by the selector lever position display
after moving the selector lever.
l If the brake pedal is not depressed and held,
the shift-lock device activates to prevent the
selector lever from being moved from the
“P” (PARK) position.
When the selector lever cannot be shifted from
the “P” (PARK) position E00629000224
When the selector lever cannot be shifted from the
“P”

(PARK) position to another position while the
brake pedal is pressed and held down with the igni-
tion switch or the operation mode in ON, the bat-
tery may be flat or the shift-lock mechanism may
be malfunctioning. Immediately have your vehicle
checked by a MITSUBISHI MOTORS Authorized
Service Point.

If you need to move the vehicle, shift the selector
lever as follows. 1. Make sure the parking brake is applied.
2. Stop the engine if it is running. Starting and driving

“P” PARK
This
position locks the transmission to prevent the
vehicle from moving. The engine can be started in
this position.
“R” REVERSE
This position is to back up. CAUTION
l
Never
shift into the “P” (PARK) or “R”
(REVERSE) position while the vehicle is
in motion to avoid a transmission damage. “N” NEUTRAL
At this position the transmission is disengaged. It is
the

same as the neutral position on a manual trans-
mission, and should only be used when the vehicle
is stationary for an extended length of time during
driving, such as in a traffic jam. WARNING
l Never
move the selector lever to the “N”
(NEUTRAL) position while driving. A se-
rious accident could occur since you
could accidentally move the lever into the
“P” (PARK) or “R” (REVERSE) position
or you will lose engine braking.
l On a gradient the engine should be star-
ted in the “P” (PARK) position, not in the
“N” (NEUTRAL) position.
l Always keep your right foot on the brake
pedal when shifting into or out of “N”
(NEUTRAL), to minimize the risk of loss
of control.
“D” DRIVE
This
position is for normal driving. The transmis-
sion automatically selects a suitable gear ratio for
your speed and acceleration.
Engine braking is automatically applied when nec-
essary, depending on road conditions. CAUTION

Sports mode
E00602500194
Whether
the vehicle is stationary or in motion,
sports mode is selected by gently pushing the selec-
tor lever from the “D” (DRIVE) position into the
manual gate (A). To return to “D” range operation,
gently push the selector lever back into the main
gate (B).

In sports mode, gear ratio shifts can be made rapid-
ly simply by moving the selector lever backward
and forward. Shift paddles at the steering wheel
can also be used to shift the gear ratio. In contrast
to a manual transmission, the sports mode allows
gear shifts with the accelerator pedal depressed.
NOTE
l You can shift into sports mode with shift pad-
dles when the selector lever is in the main
gate as well. Also, you can return to the “D”
range operation in any of following ways.
When returning to “D” range operation, the
selector lever position display will change to
“D” (DRIVE) position.
• Pull the “+ (SHIFT UP)” side shift pad-dle forward (towards the driver) for over
2 seconds.
• Stop the vehicle.
• Push the selector lever from the “D” (DRIVE) position into the manual gate
(A) and push the selector lever back into
the main gate (B).

The transmission shifts down once by each op-
eration. CAUTION
l
In
sports mode, the driver must execute
upward shifts in accordance with prevail-
ing road conditions, taking care to keep
the engine speed below the red zone.
l Repeated continuous operation of the se-
lector lever or the shift paddles will con-
tinuously switch shift position.
l Do not use the left- and right-hand shift
paddles at the same time. Doing so could
cause a shift of gear ratio that you do not
expect. NOTE
l The

upward shift may be made automatically
in sports mode when the engine revolutions
rises and approaches the tachometer’s red
zone (the red-coloured part of the tachometer
dial).
l In sports mode, only the 6 forward gears can
be selected. To reverse or park the vehicle,
move the selector lever to the “R” (RE-
VERSE) or “P” (PARK) position as required.
l To maintain good running performance, the
transmission may refuse to perform an up-
shift when the selector lever is moved to the
“+ (SHIFT UP)” position at certain vehicle
speeds. Also, to prevent over-revving of the
engine, the transmission may refuse to per-
form a downshift when the lever is moved to
the “- (SHIFT DOWN)” position at certain
vehicle speeds. When this happens, a buzzer
sounds to indicate that a downshift is not go-
ing to take place.
l In sports mode, downward shifts are made au-
tomatically when the vehicle slows down.
When the vehicle stops, 1 st
