Vehicles with steering wheel audio remote control switches
Each time the switch is pushed, the control mode changes in
the order “TARMAC” → “GRAVEL” → “SNOW” → “TAR-
MAC”.NOTE
The control mode can be changed while the vehicle is
moving.

The selected control mode is stored in memory even if the
engine is stopped.
However, if a battery terminal is disconnected, the control
mode stored in memory will be erased and the control
mode will be set to the “TARMAC” mode.
S-AWC control mode displayThe currently selected control mode is displayed on the multi-
information display.
In addition, when the control mode is changed, the selected
mode appears on the interrupt display screen of the information
screen in the multi-information display.
The control mode display will appear on the information
screen for a few seconds, and then the original screen will
return.Example: “TARMAC” mode is selected.

NOTE
If the ambient temperature drops and the viscosity of the
AWC control fluid increases, the warning may be dis-
played.
At this time, S-AWC control is temporarily suspended,
but this will not affect normal driving.
After the vehicle is driven for a while, if the engine is
restarted after the AWC control fluid warms up or the
ambient temperature increases, the S-AWC control will
start operating again if the warning display goes out.
Anti-lock braking system
N00517900295
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 hints
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 pulsation and the vibrations of the vehicle
body and steering wheel. 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.
CAUTION
!
The system may be malfunctioning.
Park your vehicle in a safe place and stop the engine.
Restart the engine and check whether the warn-
ing display and “SERVICE REQUIRED” go out.
If the warning display and “SERVICE
REQUIRED” go out, there is no abnormal condi-
tion. If the warning display and “SERVICE
REQUIRED” do not go out or appear frequently, it
is not necessary to stop the vehicle immediately, but
we recommend that you have your vehicle inspected.

An operation noise is emitted from the engine compart-
ment or feel a shock from the brake pedal when start driv-
ing immediately after starting the engine. These are
normal sound or operation that the anti-lock braking sys-
tem makes when performing a self-check. It does not indi-
cate 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).
Anti-lock braking system warning light / display
N00531600632
Warning light
Warning display
If there is a malfunction in the system, the anti-lock braking
system warning light will come on and the warning display
will appear on the information screen in the multi-information
display.
Under normal conditions, the anti-lock braking system warning
light only comes on when the ignition switch is turned to the
“ON” position and goes off a few seconds later.
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.
Do not install any aftermarket limited-slip differen-
tial (LSD) on your vehicle. The anti-lock braking
system may stop functioning properly.

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.
After driving on icy roads
N00529200035
After driving on snow or icy roads, remove any snow and ice
which may have been left around the wheels. On vehicles that
have an anti-lock braking system, be careful not to damage the
wheel speed sensors (A) or the cables located at each wheel.Front

3Active 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 4
Traction control function → P.3-129
Skid control function → P.3-129
Rear
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.

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
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.
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 operation display or ASC OFF display
N00546500091
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 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/indicator will blink.
ASC warning display
N00546600092
If an abnormal condition occurs in the system, the following
display/indicator will turn on.
Warning display
- ASC operation display/ASC indicator
The display/indicator will blink when the ASC is operat-
ing.
-ASC OFF display
The display is displayed when the ASC has been deac-
tivated 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.
- ASC indicator
-ASC OFF display
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 dis-
play/indicator goes out. If they go out, there is no
abnormal condition. If they do not go out or appear
frequently, it is not necessary to stop the vehicle
immediately, but you should have your vehicle
inspected by an authorized Mitsubishi Motors
dealer or a repair facility of your choice as soon as
possible.

3-132 Features and controls
3Limited-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.

3-134 Features and controls
3Brake assist system
N00567300034
The brake assist system is a device assisting drivers who can-
not depress the brake pedal firmly such as in emergency stop
situations and provides greater braking force.
If the brake pedal is depressed suddenly, the brakes will be
applied with more force than usual.
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.

The brake assist system may become operational 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 depressed brake pedal is soft, the pedal
moves in small motions in conjunction with the operation
noise, or the vehicle body and the steering wheel vibrate.
This occurs when the brake assist system is operating nor-
mally and does not indicate faulty operation. Continue to
depress the brake pedal.

You may hear an operation noise when the brake pedal is
depressed suddenly while stationary. This does not indi-
cate a malfunction and the brake assist system is operating
normally.
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
between vehicles in front of you without relying too
much on the brake assist system.
