S-AWC is an integrated vehicle dynamics control system that helps enhance drivingperformance, cornering performance, and vehicle stability over a wide range of driving conditions through integr
ated management of
the electronically cont
rolled 4WD, the AYC
(Active Yaw Control), the ABS and the ASC. The electronically controlled 4WD is a sys- tem that improves acceleration performance and stability performance by controlling front-rear distribution of
driving torque with
operating the electronic control coupling arranged in the rear differential assembly. The AYC is a system, with a left-right differ- ential limiting function
and yaw control func-
tion, that controls the left-right driving/braking force by managing the AFD*(Active Front Differential), the brake, the EPS. *: AFD (Active Front Differential)The Differential assembly that limits the front left-right differential
speed by operating elec-
tronic control clutch arranged in the transferassembly.
The left-right differen
tial limiting function is
a function that enhances driving performance and vehicle stability by preventing idle spin- ning of a wheel when driving on slipperyroad or when the road surfaces of left and right wheels are different. The yaw control function is a function that enhances vehicle corn
ering performance and
vehicle stability with
management of vehicle
turning power (yaw moment) by controlling the drive power difference of the left andright wheels and the braking force when the vehicle does not turn in
response to steering
input, such as when the steering wheel isturned quickly or when driving on slippery road.

Select the control mode from the followingfour types to suit the driving conditions.
S-AWC (Super-All Wheel Control)
(if so equipped)
CAUTION Do not over-rely on the S-AWC. Even the S- AWC cannot prevent the natural laws of physics from acting on the vehicle. This sys-tem, like any other sy
stem, has limits and
cannot help you to main
tain traction and con-
trol of the vehicle in
all circumstances. Reck-
less 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.
Electronically Controlled 4WD
NOTE
If the parking brake lever is pulled up while the vehicle is moving, the front-rear distribu- tion of driving torque control will turn OFF which will allow the rear wheels to lock eas-ier.
Active Yaw Control (AYC)
CAUTION Control of the braking force does not enhance the stopping performance of thevehicle, therefore, pa
y careful attention to
the safety of your surroundings when driv- ing.

When turning a sharp corner in “4WD LOCK” or “LOCK” posi
tion at low speed, a
slight difference in
steering may be experi-
enced similar to feeling as if the brakes wereapplied. This is calle
d tight corner braking
and results from each of the four tires being at a different distance from the corner. The phe-nomenon is typical of 4-
wheel drive vehicles.
If this occurs, either straighten out the steer- ing wheel or change to another mode. Set the drive mode-selector to “4WD AUTO”, “4WD LOCK” or “SNOW” inaccordance with the road conditions, and then gradually depress the accelerator pedal for a smooth start.
Set the drive mode-selector to “4WD LOCK” or “LOCK” and then gradually depress theaccelerator pedal for a
smooth start. Keep the
pressure on the accelera
tor pedal as constant
as possible, and drive at low speed.
CAUTION Setting the drive mode-selector to “4WD LOCK” or “LOCK” position to drive on drypaved road will increa
se fuel consumption,
with possible noise generation.
Turning sharp corners On snowy or icy roads
NOTE
The use of snow tires is recommended.
Maintain a safe distan
ce between vehicles,
avoid sudden braking, and use engine brak-ing (downshifting).CAUTION Avoid sudden braking,
sudden acceleration
and sharp turning. Skidding occurs and con-trol of the vehicl
e could be lost.
Driving on sandy or muddy roads
CAUTION Do not force the vehicle or drive recklessly on sandy surfaces. In comparison with nor- mal road surfaces, th
e engine and other
drive-system components are put under excessive strain when driving on such a sur- face. This could lead to accidents. If any of the follow
ing conditions occur
while the vehicle is
being driven, immedi-
ately park your vehicle
in a safe place and
follow these procedures:NOTE
• If the engine coolan

clear of people and
physical objects. The rocking motion maycause the vehicle to suddenly launch for- ward/backward, caus
ing injury or dam-
age to nearby people or objects.NOTE
Avoid sudden braking,
sudden ac
celeration
and sharp turning; such operations couldresult in the vehi
cle becoming stuck.

vehicle when operating in 4-wheel drive is greatly affected by the condition of the tires. Pay close attention to the tires. Install only the specified tires on all wheels. Refer to “Tires and wheels” on page 11-7. Be sure all four tires and wheels are the same size and type. When it is necessary to replace any of the tires or wheels, replace all four. All tires should be ro
tated before the wear
difference between the front and rear tiresis recognizable.
Good vehicle performance cannot be expected if there is a difference in wear between tires. Refer to “Tire rotation” onpage 9-20. Check the tire inflation pressure regularly.
N00517500275
Overuse of the brake can cause weakening, resulting in poor brake response and prema- ture wear of the brake pads. When driving down a long or steep hill, useengine braking by downshifting.
CAUTION Always use tires of th
e same size, type, and
brand that have no wear differences. Using tires of different size, type, brands or degree of wear, will increase the differential oil tem-perature and result in possible damage to the driving system. Further, the drive train will be subject to excessi
ve loading, possibly
leading to oil leakage,
component seizure, or
other serious failures.
To w i n g
CAUTION Do not tow 4-wheel drive vehicles with the front or rear wheels on the ground (Type A or Type B) as illustrated. This could result in damage to the drivetra
in, or unstable towing.
If you tow 4-wheel drive vehicles, use TypeC or Type D equipment. Even in “4WD ECO” drive mode, the vehi- cle cannot be towed with the front or the rear wheels on the ground.
Jacking up a 4-wheel drive vehicle
WA R N I N G Do not crank the engine while jacking up the vehicle. The tire on the ground may turn and thevehicle may roll off the jack.
Service brake Brake pedal
WA R N I N G Do not leave any obje
cts 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 emergency. Make sure that the pedal canbe operated freely at
all times. Make sure
the floor mat is securely held in place.

On slippery surfaces, the traction control function prevents the drive wheels from spin- ning excessive, thus helping the vehicle tostart moving from a stopp
ed condition.
It also
provides sufficient driv
ing force and steering
performance as the vehicle turns while press-ing the acceleration pedal.
N00559300019
The skid control function is designed to helpthe driver maintain control of the vehicle on slippery roads or during rapid steering
CAUTION If the warning display appears while the engine is running, have
the vehicle inspected
by an authorized Mitsubishi Motors dealer or a repair facility of
your choice as soon as
possible. It may become harder to turn thesteering wheel.
Active stability control (ASC)
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 driv- ing can lead to accident
s. It is the driver’s
responsibillty to drive carefully, This means taking into account the traffic, road and envi- ronmental 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 differential (LSD) on your vehicle. The ASC may stop functioning properly.NOTE
An operation noise may be emitted from the engine compartment in the following situa-tions. The sound is associated with checkingthe 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 malfunc-
tion. • 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 acti
vated, you may feel a
vibration in the vehicl
e body or hear a whin-
ing sound from the engine compartment.This indicates that th
e system is operating
normally. It does not i
ndicate a malfunction.
When the anti-lock braking system warning light is illuminated, the ASC is not active.
