3Turbocharger operation
(if so equipped)
N00537300051
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.
Engine oil must be properly maintained to avoid
engine and/or turbocharger damage. To better pro-
tect your engine and turbocharger, use fully syn-
thetic engine oil.

NOTE
To ensure proper transmission operation, stop at each
detent position when shifting. After shifting, check the
position in the multi-information display.

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.

For a shift indicated by in the illustration, depress the
brake pedal before moving the selector lever. If you
attempt to move the selector lever before depressing the
brake pedal, the selector lever will be immovable.
When the selector lever cannot be shifted from
the “P” (PARK) position
N00547400013
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 ignition switch at the “ON” position,
the battery may be flat or the shift-lock mechanism may be
malfunctioning.
Immediately have your vehicle checked by an authorized
Mitsubishi Motors dealer or a repair facility of your choice.
If you need to move the vehicle, shift the selector lever as fol-
lows.
1. Make sure the parking brake is fully applied.
2. Stop the engine if it is running.
3. Insert a screwdriver with a cloth over its tip into the notch
(A) of the cover. Pry gently as shown to remove the cover.

When the warning display or the warning display
appears on the information screen in the multi-information dis-
play while you are driving, there could be a malfunction in the
CVT.
CAUTION
!
If a malfunction occurs in the CVT while driving,
the warning display or the warning display
will appear on the information screen in the multi-
information display.
In this case, immediately park your vehicle in a safe
place and follow these procedures:
[When warning display is showing]
The continuously variable transmission (CVT) fluid
is overheating. The engine control may activate to
lower the CVT fluid temperature, causing the
engine revolutions and vehicle speed to decrease. In
this case, take one of the following procedures:
• Slow down your vehicle.
• Stop your vehicle in a safe place, put the selector
lever in the “P” (PARK) position, and open the
engine hood with the engine running to allow the
engine to cool down.After a while, confirm that the warning display is
no longer showing. It is safe to continue driving if
the display is no longer showing. If the warning dis-
play remains or flashes frequently, have your vehicle
inspected by an authorized Mitsubishi Motors
dealer or a repair facility of your choice. [When warning display is showing]
It may be that there is something unusual happening
in the CVT, causing a safety device to activate. Have
your vehicle inspected by an authorized Mitsubishi
Motors dealer or a repair facility of your choice as
soon as possible.

Sports mode display
N00538800082
In sports mode, the currently selected shift range is displayed
on the information screen in the multi-information display.NOTE
While driving in sports mode, the sports mode display
may change to show “D” and shifting in sports mode may
no longer be possible.
This indicates that controls to drive in the “D” position are
operating normally in order to lower the temperature of
the continuously variable transmission (CVT) fluid; it
does not indicate a malfunction. Once the temperature of
the continuously variable transmission (CVT) fluid drops,
shifting in the sports mode will be possible again.
Operation of the CVT
N00514500274
CAUTION
!
Before selecting a position with the engine running
and the vehicle stationary, fully depress the brake
pedal to prevent the vehicle from creeping.
Do not release the brakes until you are ready to
drive away. The vehicle will begin to move as soon as
the CVT is engaged, especially when the engine
speed is high (fast idle or air conditioning on).
Depress the brake pedal with the right foot.
Using the left foot could cause driver movement
delay in case of an emergency.
To prevent sudden acceleration, never run the
engine at high rpms when shifting from the “P”
(PARK) or “N” (NEUTRAL) position.
Operating the accelerator pedal while the other foot
is resting on the brake pedal will affect braking effi-
ciency and may cause premature wear of brake
pads.
Do not rev the engine with the brake pedal pressed
when the vehicle is stationary.
This can damage the CVT.
Also, when you depress the accelerator pedal while
holding down the brake pedal with the selector lever
in the “D” (DRIVE) position, the engine revolutions
may not rise as high as when performing the same
operation with the selector lever in the “N” (NEU-
TRAL) position.

When the CVT makes no speed change
N00515300194
If the CVT does not shift while driving, or your vehicle does
not pick up enough speed when starting on an uphill slope,
there may be something unusual happening in the transmission,
causing a safety device to activate. Have your vehicle checked
at an authorized Mitsubishi Motors dealer or a repair facility of
your choice as soon as possible.
1. If your vehicle has difficulty moving uphill, shift the
selector lever into “L” (LOW) position (except for vehi-
cles with sport mode) or 2nd shift range of the sports
mode.
This method might not work depending on the type of
transmission malfunction.
2. Once the vehicle is moving on a level road, move the
selector lever back to “D” (DRIVE) position.NOTE
When the warning display or the warning display
appears on the information screen in the multi-informa-
tion display, there could be a malfunction in the CVT.
Refer to “Continuously variable transmission (CVT):
Warning display” on page 3-99.
Twin Clutch SST
(Sportronic Shift Transmission)
(if so equipped)
N00539700059
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 two 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 1 3
Manual shift → P. 3 - 1 1 6

All-wheel drive system
(if so equipped)
N00516400033
All-wheel drive vehicles are propelled by engine power distrib-
uted constantly and appropriately to all four wheels.
Not only does this ensure enhanced handling on dry, paved
roads but also permits better traction when driving on slippery,
wet or snow-covered roads and when moving out of mud.
These vehicles, however, are not designed for off-road use,
and are unsuitable for driving on bumpy ground that may
cause excessive strain. All-wheel drive vehicles should be
driven only under the same conditions as are suitable for ordi-
nary front-wheel drive vehicles.
CAUTION
!
When the Twin Clutch SST fluid temperature is
high, the engine idle speed when the vehicle is
stopped may increase or the vehicle will have a weak
tendency to creep.
After that, if the Twin Clutch SST fluid temperature
rises even higher, the warning display will
appear.

Power brakes
N00517600377
Your vehicle is equipped with power brakes for more braking
force with minimal brake pedal effort.
Your brakes are designed to operate at full capacity, even if the
power assist is lost.
If the power assist is lost, the effort needed to press the brake
pedal is greater.
If you should loose the power assist for some reason, the
brakes will still work.
If the power brake unit or either of the two brake hydraulic sys-
tems stops working properly, the rest of the brake system will
still work, but the vehicle will not slow down as quickly.
You will know this has happened if you find you need to
depress the brake pedal down further, or harder when slowing
down or stopping, or if the brake warning light and the warning
display in the multi-information display come on.
Brake pad wear alarm
N00532500087
The disc brakes have an alarm that makes a metallic squeal
when the brake pads have worn down enough to need service.
If you hear this sound, have the brake pads replaced at an
authorized Mitsubishi Motors dealer or a repair facility of your
choice.
WARNING
!
Never coast downhill with the engine OFF. Keep the
engine running whenever your vehicle is in motion.
If you turn off the engine while driving, the power
brake booster will stop working and your brakes
will not work as well.
If the power assist is lost or if either brake hydraulic
system stops working properly, take your vehicle to
an authorized Mitsubishi Motors dealer or a repair
facility of your choice immediately.
WARNING
!
Driving with worn brake pads will make it harder to
stop, and can cause an accident.
