NOTE
For vehicles with Twin Clutch SST, the engine will stop
and the vehicle power will turn off approximately 1 sec-
ond after the ignition switch is turned to the “LOCK”
position.
The reason for this is that, in the time from when the igni-
tion switch is turned to the “LOCK” position until the
engine stops, the gears inside the Twin Clutch SST disen-
gage so that the engine will start smoothly the next time it
is started.
Two clutches installed in the Twin Clutch SST alternately
engage and disengage to achieve smooth shifting.
In addition, the gear on the side with the free clutch is
engaged, therefore, quick shifting is performed.
If the engine was stopped with the gear engaged like this,
it would provide resistance the next time the engine is
started. Therefore, the gear disengages in the approxi-
mately 1-second period until the engine stops.

For vehicles with Twin Clutch SST, do not operate the
gearshift lever or the accelerator pedal for approximately
1 second until the engine stops.
If the temperature 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 cooling fans may be
heard even after the engine is stopped. This sound is nor-
mal and does not indicate a malfunction.
After operating for a period of time, the cooling fans will
stop automatically.

3Turbocharger operation
N00537300048
TurbochargerThe turbocharger increases engine power by pushing large
amounts of air into the engine’s cylinders. The finned parts
inside the turbocharger turn at extremely high speeds and are
subjected to extremely high temperatures. They are lubricated
by engine oil and cooled by engine oil and coolant. If the
engine oil is not replaced at the specified intervals, the bearings
may seize or emit abnormal noise.
CAUTION
!
Do not run the engine at high speeds (for example,
by revving it or by accelerating rapidly) immedi-
ately after starting it.
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.
To avoid engine and/or turbocharger damage, use
only fully synthetic engine oil for this vehicle.
DO NOT use conventional petroleum based motor
oil or “blends” of conventional oil and synthetic oil.
Refer to “Recommended engine oil viscosity” on
page 7-9.

3 Clutch pedal operation
(if so equipped)
N00537700042
Observe the following cautions when using the clutch pedal.
Not observing them could result in rapid clutch wear or in
clutch damage.

Press the clutch pedal all the way down while shifting
gears.

Press and hold the clutch pedal all the way down before
starting the engine.

Do not rest your foot on the clutch pedal.

On hills and other gradients, do not hold the vehicle in
position by slipping the clutch without using the brakes.

Make sure the space under the clutch pedal is free of
objects that could obstruct the pedal.NOTE
Your vehicle has a special feature to reduce the impact
into the power train and to reduce the load of the clutch
disk; the engine revolution doesn’t rise more than around
5,500 rpm while the vehicle is stationary and the clutch
pedal has been depressed.
If either of the following occurs, the clutch should be
inspected by a Mitsubishi Motors dealer or a repair facil-
ity of your choice:
• The pedal stroke until clutch disengagement suddenly
increases.
• The engine revs when the clutch is not disengaged.
CAUTION
!
If the clutch is engaged suddenly while the engine
revolution is high, an extremely large load will be
applied instantaneously to the power train, possibly
leading to the breakage of that component. Please
ensure, therefore, that the clutch pedal is always
applied in a slow yet firm manner.

3Manual transaxle
N00512700070
The shift pattern below is shown on the gearshift lever. Press
the clutch pedal all the way down while shifting gears.NOTE
During cold weather, shifting may be difficult until the
transaxle lubricant has warmed up. This is normal and not
harmful to the transaxle.To startPress the clutch pedal all the way down and shift into 1st. Then
gradually release the clutch pedal while depressing the acceler-
ator pedal.
NOTE
If it is hard to shift into 1st, depress the clutch pedal a sec-
ond time; the shift will then be easier.Proper shift points
N00537400049
Always use care to change the gear with the vehicle speed
matched to the engine speed. Proper shifting will improve fuel
economy and prolong engine life.
CAUTION
!
Do not rest your foot on the clutch pedal because
this will cause premature clutch wear or damage.
Do not coast in the “N” (Neutral) position (illegal in
many states).
Do not use the gearshift lever as a handrest, because
this can result in premature wear of the transaxle
shift forks.
CAUTION
!
Avoid downshifting that may cause the tachometer
pointer to enter the red zone.
This puts the engine at risk of being damaged.

Upshifting
N00512900144
For the best fuel economy and performance in using your man-
ual transaxle, upshift as listed below.
Downshifting
N00513000096
It is recommended that you downshift to a lower gear when
needed to maintain the desired speed, according to the table.
Avoid downshifting at too high a speed. The engine may suffer
damage.
To maintain a safe speed and prolong brake life, shift down to
2nd or 1st when descending a steep hill.
Downshifting is also important to avoid “lugging” the engine
at too low a speed, such as when turning a corner or when driv-
ing up a steep hill.Recommended downshifting speed

Twin Clutch SST (Sportronic Shift Trans-
mission)
(if so equipped)
N00539700017
The Twin Clutch SST is a transmission that, through integrated
control of the engine and transmission, is able to achieve both
the smooth shifting of an automatic transaxle and the accelera-
tion and fuel economy close to a manual transaxle. In addition,
the control mode can be selected from three types to suit the
driving conditions.
Together with manual shifting, the transmission is capable of
responding to a variety of driving circumstances.
Twin Clutch SST control mode→ P. 3 - 1 0 3
Manual shift → P.3-105

When the gearshift lever position display blinks
N00563000017
When the gearshift lever is placed in the “R” (REVERSE)
position, the gearshift lever position display on the multi-infor-
mation display may blink and the vehicle will not move
because the gears in the transmission have not engaged.
If this occurs, perform the following procedure.
1. Depress the brake pedal with your right foot and place the
gearshift lever in the “N” (NEUTRAL) position.
2. Place the gearshift lever in the “R” (REVERSE) position,
and confirm that the gearshift lever position display stops
blinking.
3. Repeat 1 and 2 above if the gearshift lever position dis-
play continues to blink.
If the gearshift lever position display is not showing
N00562500031
There may be a problem in the Twin Clutch SST.
If this occurs, the safety device operates and prevents the vehi-
cle from moving. Therefore, perform the following procedure.
1. Park your vehicle in a safe place and stop the engine.
2. Restart the engine.
If the gearshift lever position display is shown and the vehicle
can move after this procedure is performed, there is no mal-
function.
If the gearshift lever position display is not shown and the
vehicle cannot move, or if this problem occurs repeatedly, have
the vehicle checked by an authorized Mitsubishi Motors dealer
or a repair facility of your choice as soon as possible.
WA R N I N G
!
To avoid unintended vehicle movement, keep brake
pedal applied with your right foot and do not
depress the accelerator pedal, while the gearshift
lever position display is blinking.
