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 3-115 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 in the transmission.
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.
ACD (Active center differential system)
(if so
equipped)N00538500034
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
!
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.
CAUTION
!
Do not over-rely on the ACD. Even the ACD 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 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
ACD may not work properly.

NOTE
If the ambient temperature drops and the viscosity of the
AWC control fluid increases, the warning may be dis-
played.
At this time, ACD 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 ACD control will start
operating again if the warning display goes out.
Electronically controlled 4WD system
(if so
equipped)N00548300019
The electronically controlled 4WD system is an all-wheel drive
system that allows one of three drive modes to be selected with
a switch, in accordance with the driving conditions.
The following drive modes are available.
4-wheel drive operation requires special driving skills.
Carefully read the “All-wheel driving operation” section on
page 3-139 and take care to drive safely.
Drive mode
Function
2WDThis mode is for economical
driving on normal dry roads
and freeways.
Driving in front-wheel drive.
4WD AUTOThe default mode.
This mode is for automatically
controlling the distribution of
driving torque to all four
wheels according to the driving
conditions.
4WD LOCKThis mode is for driving in slip-
pery conditions such as on
snow-covered roads or sand.
The large amount of driving
torque that is applied to the rear
tires enables getting out of slip-
pery areas and powerful driving
is possible across all ranges.

3 All-wheel driving operation
N00530600169
For vehicles with full-time 4WDFull-time 4WD vehicles are propelled by engine power distrib-
uted constantly and appropriately to all 4 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. Full-time 4WD vehicles should be
driven only under the same conditions as are suitable for ordi-
nary front-wheel drive vehicles.For vehicles with electronically controlled 4WD
systemElectronically controlled 4WD system vehicles are propelled
by engine power distributed constantly and appropriately to all
4 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. Electronically controlled 4WD system
vehicles should be driven only under the same conditions as
are suitable for ordinary front-wheel drive vehicles.
Turning sharp cornersWhen turning a sharp corner in “4WD LOCK” position at low
speed, a slight difference in steering may be experienced simi-
lar to feeling as if the brakes were applied. This is called tight
corner braking and results from each of the four tires being at a
different distance from the corner. The phenomenon is typical
of 4-wheel drive vehicles. If this occurs, either straighten out
the steering wheel, or change to “2WD” or “4WD AUTO”
mode.On snowy or icy roadsSet the drive mode-selector to “4WD AUTO” or “4WD
LOCK” in accordance with the road conditions, and then grad-
ually depress the accelerator pedal for a smooth start.NOTE
The use of snow tires is recommended.

Maintain a safe distance between vehicles, avoid sudden
braking, and use engine braking (downshifting).
CAUTION
!
Avoid sudden braking, sudden acceleration, and
sharp turning. Skidding occurs and control of the
vehicle could be lost.

3 Cautions on handling of all-wheel drive
vehicles
N00530800190
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 9-9.

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
7-35.

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.

NOTE
After your vehicle is driven a short distance after starting
the engine, you will hear the sound coming from the
engine compartment. These are the normal sounds the
anti-lock braking system makes when performing a self-
check. It does not indicate 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
N00531600573
Warning light
Warning display type 1
Warning display type 2
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 four wheels and tires are the same size
and the same type.
Never install a limited slip differential as the ABS
may not function normally.
Please consult an authorized Mitsubishi Motors
dealer.

3 Active Stability Control (ASC)
(if so equipped)
N00559100118
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 page on
the anti-lock braking system, traction control function and skid
control function.
Anti-lock braking system (ABS) → P. 3 - 1 4 7
Traction control function → P. 3 - 1 5 2
Skid control function → P. 3 - 1 5 2

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.
