Automatic transmission
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 E00629000178
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

3. Insert a straight blade (or minus) screwdriver
with a cloth over its tip into notch (A) of the
cover. Pry gently as shown to remove the cov-
er. 4. Depress the brake pedal with the right foot.
5. Turn

the ignition switch to the “ACC” posi-
tion or put the operation mode in ACC.
6. Insert a straight blade (or minus) screwdriver in the shiftlock release hole (B). Shift the se-
lector lever to the “N” (NEUTRAL) position
while pressing the straight blade (or minus)
screwdriver down. Selector lever position display

“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
l
Never
shift into the “D” (DRIVE) posi-
tion from the “R” (REVERSE) position
while the vehicle is in motion to avoid
transmission damage. Starting and driving

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
