3Anti-lock braking system
N00517900240
The anti-lock braking system helps prevent the wheels from
locking up when braking. This helps maintain vehicle drivabil-
ity and steering wheel handling.Driving hintsWhen using the anti-lock brakes (sudden braking), steer-
ing 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 vehicle 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 sit-
uations where brakes are applied suddenly. This system
may also prevent 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 vibrating and hear a unique sound. It may
also feel as if the pedal resists being pressed.
In this situation, simply hold the brake pedal down
firmly. Do not pump the brake, which will result in
reduced braking performance.
NOTEA whining sound is emitted from the engine compartment
when driving immediately after starting the engine. These
are the normal sounds the anti-lock braking system makes
when performing a self-check. It does not indicate a mal-
function.
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).
CAUTION
!The anti-lock braking system cannot prevent acci-
dents. It is your responsibility to take safety precau-
tions and 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.

3Power steering system
N00518000323
The power steering system operates while the engine is run-
ning. It helps reduce the effort needed to turn the steering
wheel.
The power steering system has mechanical steering capability
in case the power assist is lost. If the power assist is lost for
some reason, you will still be able to steer your vehicle, but
you will notice it takes much more effort to steer. If this hap-
pens, have your vehicle inspected at an authorized Mitsubishi
Motors dealer or a repair facility of your choice.
Active stability control (ASC)
N00559100147
The Active stability control (ASC) takes overall control of the
anti-lock braking system, traction control function and skid
control function to help maintain the vehicle’s control and trac-
tion. Please read this section in conjunction with the page on
the anti-lock braking system, traction control function and skid
control function.

WA R N I N G
!Do not stop the engine while the vehicle is moving.
Stopping the engine would make the steering wheel
extremely hard to turn, possibly resulting in an acci-
dent.
CAUTION
!Do not leave the steering wheel turned all the way in
one direction. This can cause damage to the power
steering system.
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
driving can lead to accidents. It is the driver’s
responsibillty to drive carefully, This means taking
into account the traffic, road and environmental
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 differen-
tial (LSD) on your vehicle. The ASC may stop func-
tioning properly.

NOTEAn operation noise may be emitted from the engine com-
partment in the following situations. The sound is associ-
ated with checking the 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 malfunction.
• When the ignition switch is set to the “ON” position.
• When the vehicle is driven for a while after the engine is
turned on.
When the ASC is activated, you may feel a vibration in
the vehicle body or hear a whining sound from the engine
compartment.
This indicates that the system is operating normally. It
does not indicate a malfunction.
When the anti-lock braking system warning light is illu-
minated, the ASC is not active.
Traction control function
N00559200021
On slippery surfaces, the traction control function prevents the
drive wheels from spinning excessive, thus helping the vehicle
to start moving from a stopped condition. It also provides suffi-
cient driving force and steering performance as the vehicle
turns while pressing the acceleration pedal.Skid control function
N00559300019
The skid control function is designed to help the driver main-
tain 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.NOTEThe skid control function operates at speeds of about 9
mph (15 km/h) or higher.
CAUTION
!When driving a vehicle on a snowy or icy road, be
sure to install snow tires and drive the vehicle at
moderate speeds.

ASC OFF switch
N00559400195
The ASC is automatically activated when the ignition switch is
turned to the “ON” position. You can deactivate the system by
pressing down the “ASC OFF” switch for 3 seconds or longer.
When the ASC is deactivated, the display/indicator will turn
on. To reactivate the ASC, momentarily press the “ASC OFF”
switch ; the display/indicator is turned off.
NOTEUsing the “ASC OFF” switch turns off both the stability
control function 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 such situations, 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 “mistaken operation protection
function” will activate and the ASC will turn back on.
CAUTION
!For safety reasons, the “ASC OFF” switch should be
operated when your vehicle is stopped. Be sure to keep the ASC on while driving in normal
circumstances.If the ASC is deactivated, the driver may lose their
grip on the steering wheel when the tires spin. Grip
the steering wheel firmly while driving.

ASC operation display or ASC OFF display
N00559500213
NOTEThe combination of items shown on the display varies
depending on the vehicle model.
NOTEThe display/indicator may come on when you start the
engine. This means that the battery voltage momentarily
dropped when the engine was started. It does not indicate
a malfunction, provided that the display goes out immedi-
ately.
When a spare tire has been put on your vehicle, the grip-
ping ability of the tire will be lower, making it more likely
that the display/indicator will blink.
- ASC operation display/ASC indicator
The display/indicator will blink when the ASC is operat-
ing.
-ASC OFF display/ASC OFF indicator
This display/indicator will turn on when the ASC is
turned off with the “ASC OFF” switch.
CAUTION
!When display/indicator blinks, ASC is operating,
which means that the road is slippery or that your
vehicle’s wheels are beginning to slip. If this hap-
pens, drive slower.If the temperature in the braking system continues
to increase due to continuous brake control on a
slippery road surface, the display/indicator will
blink. To prevent the brake system from overheat-
ing, the brake control of the traction control func-
tion will be temporarily suspended. The engine
control of the traction control function and normal
brake operation will not be affected.
Park your vehicle in a safe place. When the temper-
ature in the braking system has come down, the
display/indicator will be turned off and the traction
control function will start operating again.

!The system may be malfunctioning.
Park your vehicle in a safe place and stop the engine.
Restart the engine and check whether the dis-
play/indicator goes out. If they go out, there is no
abnormal condition. If they do not go out or if they
turn on frequently, it is not necessary to stop the
vehicle immediately, but you should have your vehi-
cle inspected by an authorized Mitsubishi Motors
dealer or a repair facility of your choice as soon as
possible.
CAUTION
!When towing the vehicle with only the front wheels
or only the rear wheels raised off the ground, do not
place the ignition switch in the “ON” position. Plac-
ing the ignition switch in the “ON” position could
cause the ASC to operate, resulting in an accident.
Note that the correct towing method depends on the
transmission type and the vehicle’s drive configura-
tion.
For details, refer to “Towing” on page 6-25.

Tire pressure monitoring system
N00530200442
The tire pressure monitoring system uses tire inflation pressure
sensors (A) on the wheels to monitor the tire inflation pres-
sures. The system only indicates when a tire is significantly
under-inflated.
WA R N I N G
!The compact spare wheel does not have a tire infla-
tion pressure sensor.
When the spare tire is used, the tire pressure moni-
toring system will not work properly.
See an authorized Mitsubishi Motors dealer as soon
as possible to replace or repair the original tire.
