play comes onAvoid hard braking and high-speed driving. 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 / display then remain off during driving,
there is no abnormal condition.
However, if the warning light / display do not disappear, or if
they come on again when the vehicle is driven, have the vehi-
cle 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


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 Active stability control (ASC)
N00559100121
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 pages on
the anti-lock braking system, traction control function and skid
control function.
Anti-lock braking system → P. 3 - 1 2 3
Traction control function → P. 3 - 1 2 8
Skid control function → P. 3 - 1 2 8
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.
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
responsibility 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.

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
N00546800010
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.
ASC OFF switch
N00559400166
When the ignition switch is turned to the “ON” position, the
ASC automatically turns ON. If the ASC OFF switch is
pressed to turn OFF the ASC, the indicator in the meter
comes on. Press the switch again to turn ON the ASC.
CAUTION
!

When driving a vehicle on a snowy or icy road, be
sure to install snow tires and drive the vehicle at
moderate speeds.
CAUTION
!

For safety reasons, press the ASC OFF switch when
the vehicle is stopped.


Be sure to turn ON the ASC for normal driving.

NOTE

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 the
ASC with the “ASC OFF” switch will make it easier to
move out your vehicle.


By pressing the ASC OFF switch, both the skid control
function and the traction control function are turned OFF.


By pressing down the “ASC OFF” switch for 3 seconds or
longer, you can deactivate the ASC and the braking con-
trol of the AYC.
At this time, the display will appear for a few sec-
onds on the information screen in the multi-information
display.
Then, the previous screen will return and the “!” mark will
come on.
Press the ASC OFF switch again to turn ON the ASC.


If the ASC OFF switch is continuously pressed after the
ASC has been turned OFF or the ASC and the braking
control of AYC have been turned off, an erroneous opera-
tion prevention function operates and the ASC is automat-
ically turned ON.

NOTE

The display may come on in the instrument cluster
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 immediately.


When a compact spare tire has been put on your vehicle,
the gripping ability of the tire will be lower, making it
more likely that the display will blink.

Warning display
If an abnormal condition occurs in the system while driving,
the warning display will be displayed at the same time.
CAUTION
!

The system may be malfunctioning.
Park your vehicle in a safe place and stop the engine.
Restart the engine again and check whether the
display, indicator and the display go out. If the
warning display goes out, there is no abnormal con-
dition. If the warning display does not go out or
appears 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.

3 Limited-slip differential
N00517400014
A limited-slip differential is applied for front wheel differen-
tial. The features of this limited-slip differential are described
below:
Just as with a conventional differential, the wheel on one side
is allowed to turn at a different speed from the wheel on the
other side when the vehicle is cornering. The difference
between the limited-slip differential and a conventional differ-
ential is that if the wheel on one side of the vehicle loses trac-
tion, a greater amount of torque is applied to the wheel on the
other side to improve traction.NOTE

Even if there is a difference in the amount of traction the
wheels can get, if both of them are spinning, the limited-
slip differential will not be effective.
Service brake
N00517500291
Brake pedalOveruse of the brake can cause poor brake response and pre-
mature wear of the brake pads.
When driving down a long or steep hill, use engine braking by
downshifting.
CAUTION
!

Never start the engine while one of the front or rear
wheels is jacked up and the other in contact with the
ground; doing so may cause the vehicle to jump for-
ward.


Continuously attempting to extract the vehicle from
snow, mud, etc. while using high engine rpm may
damage the limited-slip differential.


Using a compact spare wheel will adversely affect
the limited-slip differential; replace the compact
spare wheel with a standard size wheel as soon as
possible.
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 pedal stroke that would be necessary in an emer-
gency. Make sure that the pedal can be operated
freely at all times. Make sure the 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 can result in very high brake
temperatures, premature pad wear, and possible
damage to the brakes.
