3 Anti-lock braking system
N00517900282
The anti-lock braking system helps prevent the wheels from
locking up when braking. This helps you keep control of your
vehicle and its direction. Driving hints

When 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 to
situations 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. You
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.
NOTE

After your vehicle is driven a short distance after starting
the engine, you will hear the sound coming from the
engine compartment. These are the normal 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 approxi-
mately 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 four wheels and tires are the same size
and the same type.


Never install a limited-slip differential as the anti-
lock braking system may not function normally.
Please consult an authorized Mitsubishi Motors
dealer.

If the warning light/display comes on while driv-
ing
N00531700545
If only the anti-lock braking system warning light/dis-
play comes on

Avoid hard braking and high-speed driving. Stop the vehi-
cle 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 remain off during driv-
ing, there is no problem.
However, if the warning light/display do not disappear, or
if they come on again when the vehicle is driven, have the
vehicle checked by an authorized Mitsubishi Motors
dealer or repair facility of your choice as soon as possible.
If the anti-lock braking system warning light/display
and brake warning light/display come on at the same
timeWarning light

Warning display type 1

Warning display type 2

The anti-lock braking system and brake force distribution func-
tion may not work, so hard braking could make the vehicle
unstable.
Avoid hard braking and high-speed driving. Stop the vehicle in
a safe place and contact an authorized Mitsubishi Motors
dealer or repair facility of your choice.NOTE

The anti-lock braking system warning light and brake
warning light illuminate at the same time and the warning
displays appear alternately on the information screen in
the multi-information display.

3 Power steering system
N00518000206
The power steering system has mechanical steering capability
in case the power assist is lost. If the hydraulic pressure is
interrupted for some reason (such as engine stalling), you will
still be able to steer your vehicle.
If the power assist is lost, you will notice it takes much more
effort to steer and that there is much more “free play” in the
steering wheel. If this happens, take your vehicle to an autho-
rized Mitsubishi Motors dealer or a repair facility of your
choice.
Active stability control (ASC)
N00559100091
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.
Anti-lock braking system → P. 3 - 1 3 5
Traction control function → P. 3 - 1 4 0
Skid control function → P. 3 - 1 4 0

!

Never turn off the engine while the vehicle is mov-
ing, or your ability to steer the vehicle may be seri-
ously reduced.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.

NOTE

An 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
N00559200047
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
N00546800023
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.NOTE

The 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
N00559400140
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 will be illumi-
nated. To reactivate the ASC, momentarily press the “ASC
OFF” switch ; the display is turned off.
NOTE

Using the “ASC OFF” switch turns off both the skid con-
trol 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.

Display type 1
Display type 2
NOTE

The display 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 mal-
function, provided that the display goes out immediately.


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 will blink.
-ASC operation display
When the ASC is operating, the information screen in the
multi-information display will change and the ASC opera-
tion display will blink.
-ASC OFF display
The display is displayed when the ASC has been deac-
tivated with the “ASC OFF” switch.
-ASC indicator (if so equipped)
Indicator blinks when the ASC is operating.
CAUTION
!

When display blinks, ASC is operating, which
means that the road is slippery or that your vehicle’s
wheels are beginning to slip. If this happens, drive
slower.


If the temperature in the braking system continues
to increase due to continuous brake control on a
slippery road surface, the display will blink. To
prevent the brake system from overheating, the
brake control of the traction control function will be
temporarily suspended. The engine control of the
traction control function and normal brake opera-
tion will not be affected. Park your vehicle in a safe
place. When the temperature in the braking system
has come down, the display will be turned off and
the traction control function will start operating
again.
