When a malfunction occurs in the automatic transaxle

When the selector lever position indicator blinks

NOTE
 The “A” indicator blinks only if the CVT selector lever sw
itch is broken.
It is not seen during normal driving.
CAUTION If a malfunction occurs in the CVT while driving, the indicator will blink.In this case, immediat
ely park your vehicle
in a safe place and fo
llow these procedures:
[If the indicator blinks
rapidly (once per sec-
ond), the CVT fluid is overheating.]Park your vehicle in a safe place but do not turn off the engine. M
ove the selector lever
to the “P” (PARK) position and open theengine hood. Keep th
e engine, idling.
After a while, move the selector lever into any position other than “P” (PARK) positionand confirm that the i
ndicator stops blinking.
It is safe to continue driving if the indicator no longer blinks.If the indicator contin
ues blinking, contact
an authorized Mitsubishi Motors dealer or repair facility of your
choice i
mmediately.
[If the indicator blinks slowly (once per 2 seconds), the CVT may
be operating in fail-
safe mode due to a malfunction.]Have the vehicle inspected at an authorized Mitsubishi Motors dealer
or repair facility of
your choice immediately.
Operation of the CVT

CAUTION Before selecting a pos
ition with the engine
running and the vehicl
e stationary, firmly
depress the brake pedal to prevent the vehi- cle from creeping. The vehicle will begin to move as soon as theCVT is engaged, especi
ally when the engine
speed or idle speed is
high, or with the air
conditioning operating.Do not release the brak
e pedal until you are
ready to drive away. Depress the brake pedal
with the right foot at
all times. Using the left foot could cause driver move-ment delay in case of an emergency. To prevent sudden acce
leration, never run
the engine at high rpms when shifting from the “P” (PARK) or “N” (NEUTRAL). Operating the accelerator pedal while the other foot is resting
on the brake pedal will
affect braking efficiency and may cause pre-mature wear of brake pads.

To gain extra acceleration in “D” (DRIVE) position (when passing an
other vehicle) push
the accelerator to the floor. The CVT will automatically downshift.
For short waiting periods, such as at traffic lights, the vehicle can be
left in selector lever
position and held stationary with the servicebrake. For longer waiting periods with the engine running, place th
e selector lever in the “N”
(NEUTRAL) position and apply the parking brake, while holding the vehicle stationary with the service brake. Prior to moving off after having stopped the vehicle, make sure that the selector lever is in“D” (DRIVE) position. To park the vehicle, fi
rst bring it to a com-
plete stop, fully engage the parking brake,
and then move the selector lever to the “P” (PARK) position. If the CVT does not shift while driving, or your vehicle does not pick up enough speed when starting on an uphill slope, it may bethat there is something unusual happening in the transmission. Have your vehicle checked at an authorized Mitsubishi Motors dealer or a repair facility of your choice immediately.
N00517501328
Overuse of the brake can cause weakening,resulting in poor brake response and prema- ture wear of the brake pads.When driving down a long or steep hill, use engine braking by moving
the selector lever
to “Ds” (DOWNSHIFT & SPORTY DRIV-ING) or “L” (LOW) position.
 Use the selector lever in the correct shift position in accordance
with driving condi-
tions.Never coast downhill backward in the driv- ing shift position “D” (DRIVE), “Ds” (DOWNSHIFT & SPORTY DRIVING), “L”(LOW) or coast forward in the “R” (REVERSE) position. Engine stopping and in
creased brake pedal
and steering effort could
lead to an accident.
Do not rev the engine
with the brake pedal
pressed when the vehi
cle is stationary.
This can damage the CVT. Also, when you depress
the accelera
tor 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” (NEUTRAL) position.
Passing acceleration

CAUTION
Wa i t in g

CAUTION To avoid transmission overheating, never try to keep your vehicle stationary on a hill by using the accelerator
pedal. Always apply
the parking brake and/or service brake. Do not rev the engine unnecessarily while the vehicle is stationary. Unexpected acceler-ation may occur if the se
lector lever is in a
position other than “P” (PARK) or “N” (NEUTRAL).

N00517600436
Your vehicle is equipped with power brakes for more braking force with less brake pedaleffort. Your brakes are designed to operate at full capacity, even if the power assist is not beingused. If the power assist is not being used, the effort needed to press the brake pedal is greater.If you should lose the power assist for some reason, the brakes will still work.
If the power brake unit or either of the two brake hydraulic systems stops working prop-erly, 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 press the brake down farther, or harder when slowing down or stopping, or ifthe brake warning light and the warning dis- play in the multi-information display come on. Have the brake system repaired at an authorized Mitsubishi Motors dealer or a repair facility of your choice immediately.
N00550700124
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 fa
cility of your choice.
N00562601127
The hill start assist make
s it easy to start off
on a steep uphill slope by preventing the vehicle from moving back
wards. It keeps the
brakes applied for approximately 2 secondswhen you move your foot from the brake pedal to the accelerator pedal.
WA R N I N G Do not leave any objects near the brake pedal or let a floor mat slide under it;doing so could prevent the full pedalstroke that would be necessary in an emergency. Make sure that the pedal can be operated freely at all times. Make surethe floor mat is securely held in place.CAUTION It is important not to drive the vehicle with your foot resting on the brake pedal when braking is not required. This practice canresult in very high brake temperatures, pre- mature lining wear, a
nd possible damage to
the brakes.
Power brakes
WA R N I N G Never coast downhill
with the engine OFF.
Keep the engine running whenever your vehicle is in motion. If you turn off theengine while driving, the power brake booster will stop wo
rking 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 facil- ity of your choice immediately.
Brake pad wear alarm
WA R N I N G Driving with worn brake pads will make it harder to stop, and can cause an accident.

prevent backwards movement of the vehicle.Under certain circumstances, even when hillstart assist is activated, the vehicle may move backwards if the brake pedal is not suf- ficiently depressed, if
the vehicle is heavily
loaded, or if the road is very steep or slip- pery.  The hill start assist
is not designed to keep
the vehicle stopped in
place on uphill slopes
for more than 2 seconds. When facing uphill, do not rely on using the hill start assist to ma
intain a stopped position
as an alternative to depressing the brake pedal. Doing so could cause an accident. Do not perform the
following operation
while the hill start assist is operating.[Except for vehicles
equipped with the
F. A . S . T. - k e y ] Turn the ignition switch to the “OFF” or“ACC” position. [Vehicles equipped with the F.A.S.T.-key] Put the operation mode

N00567301116
The brake assist system is a device assisting drivers who cannot depress the brake pedalfirmly such as in em
ergency stop situations
and provides greater braking force.
If the brake pedal is depressed suddenly, the brakes will be applied with more force thanusual.
N00517900338
The anti-lock braking
system helps prevent
the wheels from locking up when braking. This helps maintain vehicle drivability andsteering wheel handling.  When using the anti-lock brakes (sudden braking), steering is slightly different from normal driving conditions. Use the steering wheel carefully. Always keep a safe distance from the vehicle in front of you. Even if your vehi- cle is equipped with
the anti-lock braking
system, leave a greater braking distance when: • Driving on gravel or snow-coveredroads. • Driving on uneven road surfaces.  Operation of anti-lock braking system is not restricted situations where brakes are applied suddenly. This system may also prevent the wheels from locking whenyou drive over manholes, steel roadwork plates, road markings
, or any uneven road
surface.

ich case the hill start
assist is again working normally. If they remain displayed or reappear fre- quently, it is not necessa
ry to stop the vehicle
immediately, but th
e vehicle should be
inspected by an authorized Mitsubishi Motors dealer or a repair facility of your choice as soon
as possible.
Brake assist system
CAUTIONThe brake assist system is not a device designed to exercise
braking force greater
than its capacity. Make
sure to always keep a
sufficient distance be
tween your vehicle and
a vehicle in front of you without relying toomuch on the brake assist system.NOTE
 Once the brake assist system is operational, it maintains great braking force even if the brake pedal is lightly released.To stop its operation, completely remove your foot from the brake pedal.  When the brake assist system is in use while driving, you may feel as if the depressed brake pedal is soft, the pedal moves in smallmotions in conjunction with the operation noise, or the vehicle body and the steering wheel vibrate. This occurs when the brakeassist system is ope
rating normally and does
not indicate faulty
operation. Continue to
depress the brake pedal.  When the anti-lock brake system warning light is illuminated, th
e brake assist system is
not functioning.

 Avoid hard braking and high-speed driv- ing. Stop the vehicle in a safe place.Test the system by restarting the engine and driving at a speed of about 12 mph (20 km/h) or higher.If the warning light then remains off dur- ing driving, there is no abnormal condi- tion.However, if the warning light does not disappear, or if they come on again when the vehicle is driven, have the vehiclechecked by an authorized MITSUBISHI MOTORS dealer or re
pair facility of your
choice as soon
as possible.
CAUTIONThe anti-lock braking system cannot prevent accidents. It is your responsibility to take safety precautions a
nd to drive carefully.
To prevent failure of the anti-lock braking system, be sure all 4 wheels and tires are the same size and the same type.NOTE
 You may feel the ope
rating sound or vibra-
tion from under the body when driving immediately after starti
ng the engine. This is
a normal result the anti-lock braking systemmakes when performing a self-check. It does not indicate a problem.  The anti-lock braking system can be used after the vehicle has
reached a speed over
approximately 6 mph (10 km/h). It stops working when the vehicle slows below 3mph (5 km/h).

WA R N I N G Do not stop the engine while the vehicle is moving. Stopping the engine would makethe steering wheel extremely hard to turn,possibly resulting
in an accident.
NOTE
During repeated full-lock turning of the steering wheel (for example, while you are manoeuvring the vehicle into a parkingspace), a protection f
unction may be acti-
vated to prevent overheating of the power steering system. This f
unction will make the
steering wheel graduall
y harder to turn. In
this event, limit your turning of the steering wheel for a while. When the system hascooled down, the steering effort will return to normal.  If you turn the steering wheel while the vehi- cle is stationary with the headlights on, the headlights may become
dim. This behavior
is not abnormal. The he
adlights will return to
their original brightness after a short while.

CAUTION Do not over-rely on the ASC. Even the ASC cannot prevent the natural laws of physicsfrom acting on the vehicle. This system, like any other system, has
limits and cannot help
you to maintain traction and control of thevehicle in all circumstances. Reckless driv- ing can lead to accident
s. It is the driver’s
responsibillty to drive carefully, This meanstaking into account the traffic, road and envi- ronmental conditions. Be sure to use the same specified type and size of tire on all four
wheels. Otherwise, the
ASC may not work properly.
 Do not install any aftermarket limited slip differential (LSD) on
your vehicle. The ASC
may stop functioning properly.NOTE
 An operating sound or vibration may be emitted from under the body in the followingsituations. The sound or vibration is associ- ated with checking th
e operations of the
ASC. At this time,
you may feel a shock
from under the body and the brake pedal if you depress it. These do
not indicate a mal-
function. • When the ignition switch is turned to the “ON” position or the
operation mode is put
in ON. • When the vehicle is driven for a while after the engine is turned on.
 When the ASC is acti
vated, you may feel a
vibration in the vehicl
e body or hear a whin-
ing sound from the engine compartment. This indicates that th
e system is operating
normally. It does not i
ndicate a malfunction.
