When the gearshift lever position display is not showing
A safety device in the Twin Clutch SST has been activated due
to a possible malfunction in the Twin Clutch SST.
Refer to “If the gearshift lever position display is not showing”
on page 3-97 and follow the appropriate measures.
When warning display is showing or when no warning is
showing in the multi-information display
A safety device in the Twin Clutch SST has been activated due
to a possible malfunction in the Twin Clutch SST or in the
engine electronic control module.
Perform the following procedure.
1. Park your vehicle in a safe place and stop the engine.
2. Restart the engine.
If the vehicle moves and accelerates normally after this proce-
dure is performed, there is no malfunction.
However, if the vehicle does not move or accelerate normally,
or if this problem occurs repeatedly, have the vehicle checked
by an authorized Mitsubishi Motors dealer or a repair facility
of your choice as soon as possible.
All-wheel drive system
N00516400020
All-wheel drive vehicles are propelled by engine power distrib-
uted constantly and appropriately to all four wheels.
Not only does this ensure enhanced handling on dry, paved
roads but also permits better traction when driving on slippery,
wet or snow-covered roads and when moving out of mud.
These vehicles, however, are not designed for off-road use,
and are unsuitable for driving on bumpy ground that may
cause excessive strain. All-wheel drive vehicles should be
driven only under the same conditions as are suitable for ordi-
nary front-wheel drive vehicles.
CAUTION
!

When the Twin Clutch SST fluid temperature is
high, the engine idle speed when the vehicle is
stopped may increase or the vehicle will have a weak
tendency to creep.
After that, if the Twin Clutch SST fluid temperature
rises even higher, the warning display will
appear.

3 S-AWC (Super-All Wheel Control)
N00541300036
S-AWC is an integrated vehicle dynamics control system that
helps enhance driving performance, cornering performance,
and vehicle stability over a wide range of driving conditions
through integrated management of the ACD, the AYC, the anti-
lock braking system, and the active stability control (ASC).
Please read this section in conjunction with the following sec-
tions.
ACD (Active center differential system) → P. 3 - 1 1 7
AYC (Active yaw control system) → P. 3 - 1 1 8
Anti-lock braking system → P. 3 - 1 2 3
Active stability control (ASC) → P. 3 - 1 2 7
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.
CAUTION
!

Do not over-rely on the S-AWC. Even the S-AWC
cannot prevent the natural laws of physics from act-
ing on the vehicle. This system, like any other sys-
tem, has limits and cannot help you to maintain
traction and control of the vehicle in all circum-
stances. Reckless driving can lead to accidents. It is
the driver’s responsibility to drive carefully. This
means taking into account the traffic, road and envi-
ronmental conditions.


Be sure to use tires that are the same specified size,
type, and brand, and have no difference in the
amount of wear for all four wheels. Otherwise, the
S-AWC may not work properly.

S-AWC warning display
N00542600049
When there is a malfunction in the system, the warning dis-
play will appear on the information screen in the multi-infor-
mation display.
In addition, the S-AWC control mode display in section A will
go out at the same time.
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.
WA R N I N G
!

Always concentrate on your driving first. Keep your
eyes and mind on the road. Distractions while driv-
ing can lead to an accident.
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.

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.

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.
