Select the control mode from the followingthree types to suit the driving conditions.
When the ignition switch is set to the “ON” position, operate the AWC switch to change the control mode. Each time the switch is pushed, the control mode changes in the order “TARMAC”

“GRAVEL”
 “SNOW”
 “TARMAC”.
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.

(if so equipped)
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 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 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 ACD may not work properly.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 eas-ier.

N00548300019
The electronically controlled 4WD system is an all-wheel drive system that allows one of three drive modes to be selected with aswitch, in accordance with the driving condi- tions. The following drive modes are available.
4-wheel drive operation requires special driv- ing skills. Carefully read the “All-wheel driving opera- tion” section on page 5-86 and take care todrive safely.
N00548400010
The drive mode can be selected by pressingthe switch while the ignition switch is in the “ON” position.
The drive mode is displayed as an interrupt display on the information screen in the multi-information display when the drive mode is switched.After a few seconds, the information screenreturns from the drive mode display to the previous screen.
NOTE
 If the ambient temperature drops and the vis- cosity of the AWC control fluid increases, the warning may be displayed. At this time, ACD control is temporarily sus- pended, but this will not affect normal driv-ing. After the vehicle is driven for a while, if the engine is restarted after the AWC controlfluid warms up or the ambient temperature increases, the ACD control will start operat- ing again if the warning display goes out.

N00530600169
Full-time 4WD vehicles are propelled by engine power distributed constantly andappropriately to all 4 wheels. Not only does this ensure enhanced handling on dry, paved roads but also permits bettertraction when driving on slippery, wet orsnow-covered roads and 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.
Full-time 4WD vehicles
should be driven only under the same condi- tions as are suitable for ordinary front-wheel drive vehicles. Electronically controlled 4WD system vehi- cles 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 designedfor 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. When turning a sharp corner in “4WD LOCK” position at low speed, a slight differ- ence in steering may be experienced similarto 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 dis-tance from the corner. The phenomenon is typical of 4-wheel drive vehicles. If this occurs, either straighten out the steeringwheel, or change to “2WD” or “4WD AUTO” mode. Set the drive mode-selector to “4WD AUTO” conditions, and then gradually depress theaccelerator pedal for a smooth start.
CAUTION The warning display on the information screen in the multi-information display, a problem has occurred with the electronically controlled 4WD system and the safety device has activated. Have an inspection made byan authorized Mitsubishi Motors dealer or a repair facility of your choice as soon as pos- sible.
Type 1 Type 2
CAUTION Always use tires of the same size, type, and brand that have no wear differences. Using tires that differ in size, type, brand, or wear amount may activate the protection of thedrive-system components, causing the drive mode in “4WD AUTO” mode to lock or the “4WD” and “LOCK” indicators to blinkalternately.

Set the drive mode-selector to “4WD LOCK” and then gradually depress the accelerator pedal for a smooth start. Keep the pressure on the accelerator pedal asconstant as possible, and drive at low speed.
Your vehicle may not provide sufficient hill climbing ability and engine braking on steepslopes. Avoid driving on steep slopes even though the vehicle is a 4-wheel drive vehicle.
N00530800190
Since driving torque can
be applied to all four
wheels, the performance 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 11-5.  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 necessary, replace all of them.  All tires should be rotated whenever the wear difference between the front and rear tires is recognizable.
NOTE
 The use of snow tires is recommended.  Maintain a safe distance 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 vehicle could be lost.
Moving out of mud
CAUTION If any of the following conditions occur, fol- low these procedures:• The engine coolant temperature display appears on the information screen in the multi-information display or the engine power drops suddenly. Refer to “Engine overheating” on page 8-4.
• The “ ” warning display or the “ ” warning display appear on the information screen in the multi-information display. Refer to “Warning display” on page 5-64.WA R N I N G When attempting to rock your vehicle out of a stuck position, be sure that the area around the vehicle is clear of people and physical objects. The rocking motion may cause the vehicle to suddenly launch for- ward/backward, causing injury or dam-age to nearby people or objects.NOTE
 Avoid sudden braking, sudden acceleration and sharp turning; such operations couldresult in the vehicle becoming stuck.  If the vehicle becomes stuck in muddy roads, it can often be moved with a rocking motion. Move the selector lever alternately between “D” (DRIVE) and “R” (REVERSE) posi-tions, while pressing lightly on the accelera- tor pedal.CAUTION
