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 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.
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 four
wheels, 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.
When the gearshift lever position display is not showing When warning display is showing or when no warning is showing in the multi- information display
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.

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.5-72
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
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 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.

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.
The left-right differential limiting function is a function that enhances driving performance and vehicle stability by preventing idle spin-ning of a wheel when driving on slippery road surfaces or when the road surfaces of the left and right wheels are different. The yaw control function is a function that enhances vehicle cornering performance by controlling the drive power difference of theleft and right wheels
and the braking force
when the vehicle does not turn in response to steering input, such as when the steeringwheel is turned quickly or when driving on slippery road surfaces.
N00542401057
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”.
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.

N00559200021
On slippery surfaces, the traction control function prevents the drive wheels from spin-ning excessive, thus helping the vehicle to start moving from a stopped condition. It also provides sufficient driving force and steeringperformance as the vehicle turns while press- ing the acceleration pedal.
N00546800010
The skid control function is designed to help the driver maintain control of the vehicle onslippery roads or during rapid steering
maneuvers. It works by controlling the engine output and the brake on each wheel.
N00559400209
When the ignition switch is turned to the “ON” position, the ASC automatically turns ON. If the ASC OFF switch is pressed to turn OFF the ASC, the display in the meter comes on. Press the switch again to turn ON the ASC.
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.
 When the ASC is activated, you may feel a vibration in the vehicle body or hear a whin- ing sound from the engine compartment. This indicates that the system is operating normally. It does not indicate a malfunction.  When the anti-lock braking system warning light is illuminated, the ASC is not active.
Traction control function
CAUTION When driving a vehicle on a snowy or icy road, be sure to install snow tires and drivethe vehicle at moderate speeds.
Skid control function
NOTE
NOTE
 The skid control function operates at speeds of about 9 mph (15 km/h) or higher.
ASC OFF switch
CAUTION For safety reasons, press the ASC OFF switch when the vehicle is stopped.

How to change a tire 8-10 For emergencies
8
8. Lower the vehicle slowly by rotating the wheel nut wrench counterclockwise until the tire touches the ground.
9. Tighten the nuts in the order shown in the illustration until each nut has been tight- ened to the torque listed here. 65 to 80 ft-lb (88 to 108 N•m)
10. Lower the jack all the way and remove it.
11. Check the tire inflation pressure. The rec-
ommended tire pressure for your vehicle is listed on the tire and loading informa- tion placard attached to the driver’s doorsill as shown in the illustration. Refer to “Tire inflation pressures” on page 9-16.
CAUTION Never apply oil to either the wheel bolts or the nuts or they will tighten too much.NOTE
 Flange nuts can be temporarily used on the compact spare or steel wheel, but return them to the original wheel and tire as soon aspossible.  If all four wheels are changed to steel wheels, use tapered nuts.
CAUTION Never use your foot or a pipe extension to apply added force to the wheel nut wrench when tightening the wheel nuts. If you do so, you can over-tighten the wheel nuts anddamage the wheel, wheel nuts and hub bolts.
CAUTION Driving with an improperly inflated tire can cause an accident. If
you have no choice but
to drive with an under-inflated tire, keep your speed down and avoid sudden steering or braking, if possible
. Inflate the tire to the
correct pressure as soon as possible. Refer to “Tire inflation pressures” on page 9-16. After changing the tire and driving the vehi- cle about 620 miles (1,000 km), retighten the wheel nuts to make sure that they have notcome loose.
