ACD (Active center differential system)
N00541400011
The ACD is a system that improves acceleration performance
and straight-ahead stability by regulating the differential limit-
ing action and power drive distribution of the center differen-
tial.NOTE
If the parking brake lever is pulled up while the vehicle is
moving, the center differential is designed to switch to a
free state condition which will allow the rear wheel to
lock easier.
AYC (Active yaw control system)
N00541500012
The AYC is a system, with a left-right differential limiting
function and yaw control function, that enhances cornering
performance and stability during cornering by controlling the
left-right drive power difference of the rear wheels, the braking
force of all four wheels, and the vehicle yaw moment. Left-right differential limiting functionThe left-right differential limiting function is a function that
enhances driving performance and vehicle stability by prevent-
ing idle spinning of a wheel when driving on slippery road sur-
faces or when the road surfaces of the left and right wheels are
different.Yaw control functionThe yaw control function is a function that enhances vehicle
cornering performance by controlling the drive power differ-
ence of the left and right wheels and the braking force when the
vehicle does not turn in response to steering input, such as
when the steering wheel is turned quickly or when driving on
slippery road surfaces.
CAUTION
!
Control of the braking force does not enhance the
stopping performance of the vehicle, therefore, pay
careful attention to the safety of your surroundings
when driving.

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.

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.

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.

3 Power steering system
N00518000293
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. 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 authorized Mit-
subishi Motors dealer or a repair facility of your choice.
Cruise control
N00518300472
Cruise control is an automatic speed control system that keeps
a set speed. It can be activated at speeds from about 25 mph
(40 km/h). Cruise control does not work at speeds below about
25 mph (40 km/h).NOTE
Cruise control may not be able to keep your speed on
uphills or downhills.

Your speed may decrease on a steep uphill. You may use
the accelerator pedal if you want to stay at your set speed.

Your speed may increase to more than the set speed on a
steep downhill. You have to use the brake to control your
speed. As a result, the set speed driving is deactivated.
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
!
When you do not wish to drive at a set speed, turn
off the cruise control for safety.
Do not use cruise control when driving conditions
will not allow you to stay at the same speed, such as
in heavy traffic or on roads that are winding, icy,
snow-covered, wet, slippery, on a steep downhill
slope.
On vehicles with manual transaxle, do not move the
gearshift lever to the “N” (Neutral) position while
driving at a set speed without depressing the clutch
pedal. The engine will run too fast and might be
damaged.

If the warning light/display illuminates while
driving
N00532800413
1. If the tire pressure monitoring system warning light illu-
minates, avoid hard braking, sharp steering maneuvers
and high speeds. You should stop and adjust the tires to
the proper inflation pressure as soon as possible. Adjust
the spare tire at the same time. Refer to “Tires” on page 7-
19.NOTE
In addition, the warning display is displayed on the infor-
mation screen in the multi-information display.

When inspecting or adjusting the tire pressure, do not
apply excessive force to the valve stem to avoid breakage.

After inspecting or adjusting the tire pressure, always
reinstall the valve cap on the valve stem.
Without the valve cap, dirt or moisture could get into the
valve, resulting in damage to the tire inflation pressure
sensors.

Do not use metal valve caps, which may cause a metal
reaction, resulting in corrosion and damage of the tire
inflation pressure sensor.

Once adjustments have been made, the warning light will
go off after a few minutes of driving.
2. If the tire pressure monitoring system warning light
remains illuminated after you have been driving for about
20 minutes after you adjust the tire inflation pressure, one
or more of the tires may have a puncture. Inspect the tire
and if it has a puncture, have it repaired by an authorized
Mitsubishi Motors dealer as soon as possible.
NOTE
To avoid the risk of damage to the tire inflation pressure
sensors, have any punctured tire repaired by an authorized
Mitsubishi Motors dealer. If the tire repair is not done by
an authorized Mitsubishi Motors dealer, it is not covered
by your warranty.

Do not use an aerosol puncture-repair spray on any tire.
Such a spray could damage the tire inflation pressure sen-
sors. Have any puncture repaired by an authorized Mit-
subishi Motors dealer.
WA R N I N G
!
If the warning light / display illuminates while you
are driving, avoid hard braking, sharp steering
maneuvers and high speeds. Driving with an under-
inflated tire adversely affects vehicle performance
and can result in an accident.
CAUTION
!
If a tire has a puncture, replace that tire with the
spare tire. Driving on a punctured tire could lead to
an accident.
The warning light / display may not illuminate
immediately in the event of a tire blowout or rapid
leak.
