N00567301099
The brake assist system
is a device assisting
drivers who cannot depress the brake pedal firmly 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 than
usual.
N00517900240
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-covered roads. • Driving on uneven road surfaces. Operation of anti-lock braking system is not restricted situati
ons where brakes are
applied suddenly. This system may alsoprevent the wheels from locking when you drive over manholes, steel roadwork plates, road markings
, or any uneven road
surface. When the anti-lock braking system is in use, you may feel the brake pedal vibrat-ing and hear a unique
sound. It may also
feel as if the pedal
resists being pressed.
In this situation, simply hold the brakepedal down firmly. Do not pump the brake, which will result in reduced braking performance.
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 vehicles in front
of you without relying too much on the brake assist system.NOTE
Once the brake assist system is operational, it maintains great braking force even if thebrake pedal is lightly released.To stop its operation, completely remove your foot from the brake pedal. The brake assist system may become opera- tional when the brake pedal is fully depressed even if it
has not been depressed
suddenly.
When the brake assist system is in use while driving, you may feel as if the depressedbrake 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. You may hear an operation noise when the brake pedal is suddenl
y or fully depressed
while stationary. This
does not indicate a
malfunction and the brake assist system is operating normally. When the anti-lock brake system warning light or only active st
ability control warning
light illuminate, the brake assist system in not functioning.

Avoid hard braking and high-speed driv- ing. Stop the vehicl
e 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 / display then remains off during driving, there is no abnormalcondition. However, if the warning light / display do not disappear, or if they come on againwhen the vehicle is driven, have the vehi- cle checked by an au
thorized Mitsubishi
Motors dealer or re
pair facility of your
choice as soon
as possible.
CAUTIONThe anti-lock braking system cannot prevent accidents. It is your
responsibility to take
safety precautions and to drive carefully. To prevent failure of the anti-lock braking system, be sure all 4 wheels and tires are thesame size and the same type.NOTE
A whining sound is emitted from the engine compartment when driving immediately after starting the engine. These are the nor-mal sounds the anti-lock braking system makes when performing a self-check. It does not indicate
a malfunction.
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 3 mph (5 km/h).

The power steering system operates while the engine is running. It
helps reduce the effort
needed to turn the steering wheel.The power steering sy
stem has mechanical
steering capability in case the power assist is lost. If the power assist is lost for some rea-son, you will still be able to steer your vehi- cle, but you will notice it takes much more effort to steer. If this happens, have your vehi- cle inspected at an authorized Mitsubishi Motors dealer or a repair facility of yourchoice.

NOTE
During repeated full-lock turning of the steering wheel (for example, while you aremanoeuvring the vehicle into a parkingspace), a protection f
unction may be acti-
vated to prevent overheating of the power steering system. This fu
nction 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 If the warning display appears while the engine is running, have
the vehicle inspected
by an authorized Mitsubishi Motors dealer or a repair facility of
your choice as soon as
possible. It may become harder to turn thesteering wheel.
Active stability control (ASC)
CAUTION Do not over-rely on the ASC. Even the ASC cannot prevent the natural laws of physics from acting on the vehicle. This system, like any other system, has
limits and cannot help
you to maintain traction and control of the vehicle in all circumstances. Reckless driv- ing can lead to accident
s. It is the driver’s
responsibillty to drive carefully, This means taking 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 af
termarket limited slip
differential (LSD) on your vehicle. The ASC may stop functioning properly.NOTE
An operation noise may be emitted from the engine compartment in the following situa-tions. The sound is associated with checkingthe operations of the ASC. At this time, you may feel a shock from the brake pedal if you depress it. These do not indicate a malfunc-tion. • When the ignition switch is set to the “ON” position. • When the vehicle is driven for a while after the engine is turned on.

N00559200021
On slippery surfaces, the traction control function prevents the drive wheels from spin- ning excessive, thus helping the vehicle tostart moving from a stopp
ed condition.
It also
provides sufficient driv
ing force and steering
performance as the vehicle turns while press-ing the acceleration pedal.
N00559300019
The skid control function is designed to helpthe driver maintain control of the vehicle on slippery roads or during rapid steering
maneuvers. It works by controlling the engine output and the brake on each wheel.
N00559401264
The ASC is automatically activated when theignition switch is turned to the “ON” posi- tion. You can deactivate
the system by press-
ing down the “ASC OFF” switch for 3seconds or longer. When the ASC is deactivated, the indica- tor will turn on. To reactivate the ASC, momentarily press the “ASC OFF” switch; the indicator is turned off.
N00559501223
When the ASC is acti
vated, you may feel a
vibration in the vehicle 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.
When the anti-lock braking system warning light is illuminated, the ASC is not active.
Traction control function
CAUTION When driving a vehicle on a snowy or icy road, be sure to install snow tires and drive the vehicle at moderate speeds.
Skid control function
NOTE
NOTE
The skid control func
tion operates at speeds
of about 9 mph (15 km/h) or higher.
ASC OFF switch
CAUTION For safety reasons, the “ASC OFF” switch should be operated when your vehicle isstopped. Be sure to keep the ASC on while driving in normal circumstances.NOTE
Using the “ASC OFF” switch turns off both the stability control f
unction and the traction
control function. When moving out of mud, sand or fresh snow, pressing the accelerator pedal may not allow the engine speed to increase. In suchsituations, temporarily turning off ASC with the “ASC OFF” switch will make it easier to move out your vehicle. If you continue to press the “ASC OFF” switch after the ASC is turned off, the “mis-taken operation
protection function” will
activate and
the ASC will turn back on.

When the FCM judges that a collision with the vehicle straight-ahe
ad is imminent, the
system will automati
cally apply moderate
braking to warn you to apply the brakes immediately. When the FCM judges that a collision withthe vehicle straight-ahead is highly unavoid- able, the system will apply emergency brak- ing to reduce the severity of the collision and, if possible, to avoid the collision. Stop lights are illuminated during automaticbraking.

If the system judges that there is a risk ofyour vehicle colliding with a vehicle in front, this function warns you
of the potential haz-
ard with visual and audible alarms.When this function is triggered, a buzzer sounds and, at the sa
me time, a “BRAKE”
message appears on the
information screen of
the multi-information display. The FCM will also prepare to provide quick brake response and greater brake force whenyou apply the brakes.
N00577700031
When the FCM judges that a collision withthe vehicle straight-ahe

FCM will automatically apply moderate brak- ing to warn the driver to apply the brakesimmediately. If the FCM judges that
the collision is highly
unavoidable, it will
automatically apply
emergency braking to reduce the severity of the collision and, if possible, to avoid the col- lision.When the FCM applies emergency braking, a buzzer sounds and a wa

WA R N I N GBefore using the FCM, read this entire section to fully understand the limitations of this system. Failure to follow instruc-tions could result
in an accident.
The FCM is designed
to help avoid certain
frontal collisions or reduce the crashspeed in such collisions. It is not a substi-tute for your safe and careful driving. Under certain circumstances, the system may not operate or may not detect cor-rectly a vehicle in fr
ont. When your vehi-
cle is approaching a
vehicle too closely,
take all necessary ac
tions to avoid a colli-
sion, such as braking
and steering, regard-
less of whether the FCM is activated or not. Never rely on the FCM to prevent acollision.
