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 arepair facility of your choice as soon as possi- ble.
N00516400020
All-wheel drive vehicles are propelled by engine power distributed constantly andappropriately 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 orsnow-covered roads a
nd when moving out of
mud. These vehicles, however, are not designedfor 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 condi-
tions as are suitable for ordinary front-wheel drive vehicles.
N00530800174
Since driving torque can be applied to all fourwheels, the performance of the vehicle whenoperating 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 11-5. Be sure to fit all four tires and wheels of the same size and type. When replacement of any of the tires orwheels is necessary, replace all of them.  All tires should be rotated whenever the wear difference between the front and reartires is recognizable.
Good vehicle performance cannot be expected if there is a difference in wear between tires. Refer to “Tire rotation” onpage 9-18.  Check the tire inflation pressure regularly.
CAUTIONWhen the Twin Clutch SST fluid tempera- ture is high, the engine idle speed when the vehicle is stopped may increase or the vehi- cle will have a weak tendency to creep.After that, if the Twin Clutch SST fluid tem- perature rises even higher, the warning display will appear.

Cautions on handling of all- wheel drive vehicles Tires and wheels
CAUTION Always use tires of the same size, same type, and same brand, and which have no wear dif- ferences. Using tires that differ in size, type, brands or the degree of wear, will increase the differential oil temperature, resulting inpossible damage to the driving system. Fur- ther, the drive train will be subjected to excessive loading, possibly leading to oilleakage, component seizure, or other serious problems.

S-AWC (Super-All Wheel Control)
Features and controls 5-71
5
N00541300036
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 integrated management ofthe ACD, the AYC, the anti-lock braking sys- tem, and the active stability control (ASC).
Please read this section in conjunction with the following sections. ACD (Active center differential system)

P.5-71AYC (Active yaw control system)
 P.5-71
Anti-lock braking system
 P.5-74
Active stability control (ASC)
 P.5-76
N00541400011
The ACD is a system
that improves accelera-
tion performance and straight-ahead stabilityby regulating the differential limiting action
and power drive distribution of the center dif- ferential.
N00541500012
The AYC is a system, with a left-right differ-ential limiting function and yaw control func-tion, that enhances cornering performance and stability during cornering by controlling the left-right drive power difference of therear wheels, the braking force of all four wheels, and the vehicle yaw moment.
CAUTION Do not tow all-wheel dr
ive vehicles with the
front or rear wheels on the ground (Type A or Type B) as illustrated. This could result in damage to the drivetrain, or unstable towing. If you tow all-wheel drive vehicles, use TypeC or Type D equipment.
Jacking up all-wheel drive vehi- cles
WA R N I N G Do not start or run the engine while the vehicle is on the jack. The jack could slip out of position andresult in an accident.
S-AWC (Super-All Wheel Control)
CAUTION Do not over-rely on the S-AWC. Even the S- AWC cannot prevent the natural laws ofphysics from acting on the vehicle. This sys- tem, like any other system, has limits and cannot help you to maintain 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. Be sure to use tires that are the same speci- fied size, type, and brand, and have no differ- ence in the amount of wear for all fourwheels. Otherwise,
the S-AWC may not
work properly.
ACD (Active center differential system)
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 conditionwhich will allow the rear wheel to lock eas- ier.
AYC (Active yaw control sys- tem)
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 driv-ing.

Active stability control (ASC) 5-76 Features and controls

N00529200035
After driving on snow or icy roads, remove any snow and ice which may have been left around the wheels. On vehicles that have an anti-lock braking system, be careful not todamage the wheel speed sensors (A) or the cables located at each wheel.
N00559100121
The active stability control (ASC) takes over- all control of the anti-lock braking system, traction control function and skid control function to help maintain the vehicle’s controland traction. Please read
this section in con-
junction with the pages on the anti-lock brak- ing system, traction control function and skid control function. Anti-lock braking system
 P.5-74
Traction control function
 P.5-77
Skid control function
 P.5-77
NOTE
The anti-lock braking system warning light and brake warning light illuminate at the same time and the warning displays appear alternately on the information screen in the multi-information display.

CAUTION Do not over-rely on the ASC. Even the ASC cannot prevent the natural laws of physics from acting on the vehicl
e. This system, like
any other system, has limits and cannot help you to maintain traction and control of thevehicle in all circumstances. Reckless driv- ing can lead to accidents. It is the driver’s responsibility to drive carefully. This meanstaking 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 ASCmay stop functioning properly.NOTE
 An operation noise may be emitted from the engine compartment in the following situa-tions. The sound is associated with checking the operations of the ASC. At this time, you may feel a shock from the brake pedal if youdepress 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.
