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 Cautions on handling of all-wheel drive
vehicles
N00530800174
Tires and wheelsSince driving torque can be applied to all four wheels, the per-
formance of the vehicle when operating in all-wheel drive is
greatly affected by the condition of the tires.
Pay close attention to the tires.

Install specified tires on all wheels. Refer to “Tires and
wheels” on page 9-8.


Be sure to fit all four tires and wheels of the same size and
type.
When replacement of any of the tires or wheels is neces-
sary, replace all of them.


All tires should be rotated whenever the wear difference
between the front and rear tires is recognizable.
Good vehicle performance cannot be expected if there is a dif-
ference in wear between tires. Refer to “Tire rotation” on page
7-26.


Check the tire inflation pressure regularly.
CAUTION
!

Always use tires of the same size, same type, and
same brand, and which have no wear differences.
Using tires that differ in size, type, brands or the
degree of wear, will increase the differential oil tem-
perature, resulting in possible damage to the driving
system. Further, the drive train will be subjected to
excessive loading, possibly leading to oil leakage,
component seizure, or other serious problems.

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.

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.
S-AWC control mode
N00542400047
Select the control mode from the following three types to suit
the driving conditions.
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.

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.
