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.

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.

Limited-slip differential (if so equipped) 5-88 Features and controls
5
Good vehicle performance cannot be expected if there is a difference in wear between tires. Refer to “Tire rotation” on page 9-23.  Check the tire inflation pressure regularly.
N00517400069
A limited-slip differential is applied for rear wheel differential. The features of this lim-ited-slip differential are described below: Just as with a conventional differential, the wheel on one side is allowed to turn at a dif- ferent speed from the wheel on the other sidewhen the vehicle is cornering. The difference between the limited-slip differential and a conventional differential is that if the wheelon one side of the vehicle loses traction, a greater amount of torque is applied to the wheel on the other side to improve traction.
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.
To w i n g
CAUTION Do not tow all-wheel drive vehicles with the front or rear wheels on the ground (Type Aor Type B) as illustrated. This could result in damage to the drivetrain, or unstable towing. If you tow all-wheel drive vehicles, use Type C or Type D equipment. [For vehicle equipped with the Electronically controlled 4WD system] Even in “2WD” mode, the vehicle cannot betowed with the front or the rear wheels on the ground.
Jacking up a all-wheel drive vehicles
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 and result in an accident.

If an abnormal condition occurs in the sys- tem, the following display/indicator will turnon.
Warning display
N00517900309
The anti-lock braking system helps prevent the wheels from locking up when braking.This helps you keep co
ntrol of your vehicle
and its direction.
 When using the anti-lock brakes (sudden braking), steering is slightly different from normal driving conditions. Use thesteering wheel carefully.  Always keep a safe distance from the vehicle in front of you. Even if your vehi-cle is equipped with the anti-lock braking system, leave a greater braking distance when:• Driving on gravel or snow-coveredroads. • Driving on uneven road surfaces.  Operation of anti-lock braking system is not restricted to situations where brakes are applied suddenly. This system may also prevent the wheels from lockingwhen you drive over manholes, steel roadwork plates, road markings, or any uneven road surface.  When the anti-lock braking system is in use, you may feel the brake pedal vibrat- ing and hear a unique sound. You mayalso feel as if the pedal resists being pressed. In this situation, si
mply hold the brake
pedal down firmly. Do not pump the brake, which will result in reduced braking performance.
NOTE
 The hill start assist is activated when all of the following conditions are met. • The engine is running. (The hill start assist will not be activated while the engine is starting or immediatelyafter the engine is started.) • The gearshift lever is in any position other than “P” (PARK) or “N” (NEUTRAL). • The vehicle is completely stationary, with the brake pedal depressed. • The parking brake is released. The hill start assist w
ill not operate if the
accelerator pedal is depressed before thebrake pedal is released.  The hill start assist also operates when reversing on an uphill slope.
