3All-wheel drive system
N00516400020
All-wheel drive vehicles are propelled by engine power distrib-
uted constantly and appropriately 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 or snow-covered roads and when moving out of mud.
These vehicles, however, are not designed for 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 conditions as are suitable for ordi-
nary front-wheel drive vehicles.
Cautions on handling of all-wheel drive
vehicles
N00530800174
Tires and wheelsSince driving torque can be applied to all four wheels, the per-
formance 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 9-8.

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 neces-
sary, replace all of them.

All tires should be rotated whenever the wear difference
between the front and rear tires is recognizable.
Good vehicle performance cannot be expected if there is a dif-
ference in wear between tires. Refer to “Tire rotation” on page
7-26.

Check the tire inflation pressure regularly.

To w i n g
CAUTION
!
Always use tires of the same size, same type, and
same brand, and which have no wear differences.
Using tires that differ in size, type, brands or the
degree of wear, will increase the differential oil tem-
perature, resulting in possible damage to the driving
system. Further, the drive train will be subjected to
excessive loading, possibly leading to oil leakage,
component seizure, or other serious problems.
CAUTION
!
Do not tow all-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 driv-
etrain, or unstable towing.
If you tow all-wheel drive vehicles, use Type C or
Type D equipment.

Jacking up all-wheel drive vehicles
S-AWC (Super-All Wheel Control)
N00541300036
S-AWC is an integrated vehicle dynamics control system that
helps enhance driving performance, cornering performance,
and vehicle stability over a wide range of driving conditions
through integrated management of the ACD, the AYC, the anti-
lock braking system, and the active stability control (ASC).
Please read this section in conjunction with the following sec-
tions.
ACD (Active center differential system) → P. 3 - 1 1 9
AYC (Active yaw control system) → P. 3 - 1 1 9
Anti-lock braking system → P. 3 - 1 2 4
Active stability control (ASC) → P.3-128
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.
CAUTION
!
Do not over-rely on the S-AWC. Even the S-AWC
cannot prevent the natural laws of physics from act-
ing on the vehicle. This system, like any other sys-
tem, has limits and cannot help you to maintain
traction and control of the vehicle in all circum-
stances. Reckless driving can lead to accidents. It is
the driver’s responsibility to drive carefully. This
means taking into account the traffic, road and envi-
ronmental conditions.
Be sure to use tires that are the same specified size,
type, and brand, and have no difference in the
amount of wear for all four wheels. Otherwise, the
S-AWC may not work properly.

ACD (Active center differential system)
N00541400011
The ACD is a system that improves acceleration performance
and straight-ahead stability by regulating the differential limit-
ing action and power drive distribution of the center differen-
tial.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 easier.
AYC (Active yaw control system)
N00541500012
The AYC is a system, with a left-right differential limiting
function and yaw control function, that enhances cornering
performance and stability during cornering by controlling the
left-right drive power difference of the rear wheels, the braking
force of all four wheels, and the vehicle yaw moment. Left-right differential limiting functionThe left-right differential limiting function is a function that
enhances driving performance and vehicle stability by prevent-
ing idle spinning of a wheel when driving on slippery road sur-
faces or when the road surfaces of the left and right wheels are
different.Yaw control functionThe yaw control function is a function that enhances vehicle
cornering performance by controlling the drive power differ-
ence of the left and right wheels and the braking force when the
vehicle does not turn in response to steering input, such as
when the steering wheel is turned quickly or when driving on
slippery road surfaces.
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 driving.

S-AWC control mode
N00542400047
Select the control mode from the following three types to suit
the driving conditions.
S-AWC control mode switchWhen the ignition switch is set to the “ON” position, operate
the AWC switch to change the control mode.
Except for vehicles with steering wheel audio remote con-
trol switches
Push the switch down to change the control mode in the order
“TARMAC” → “GRAVEL” → “SNOW” or push it up to
change the control mode in the order “SNOW” → “GRAVEL”
→ “TARMAC”.

Operation
TA R M A CNormally, use this control mode. Use this
mode for paved roads.
GRAVELUse this control mode when driving on some-
what slippery road surfaces, such as wet road
surfaces and gravel roads.
SNOWUse this control mode when driving on slip-
pery road surfaces, such as snow-covered
roads.

Vehicles with steering wheel audio remote control switches
Each time the switch is pushed, the control mode changes in
the order “TARMAC” → “GRAVEL” → “SNOW” → “TAR-
MAC”.NOTE
The control mode can be changed while the vehicle is
moving.

The selected control mode is stored in memory even if the
engine is stopped.
However, if a battery terminal is disconnected, the control
mode stored in memory will be erased and the control
mode will be set to the “TARMAC” mode.
S-AWC control mode displayThe currently selected control mode is displayed on the multi-
information display.
In addition, when the control mode is changed, the selected
mode appears on the interrupt display screen of the information
screen in the multi-information display.
The control mode display will appear on the information
screen for a few seconds, and then the original screen will
return.Example: “TARMAC” mode is selected.

S-AWC operation display
N00542500048
The S-AWC operation status can be displayed on the informa-
tion screen in the multi-information display.
To display the status, press the multi-information meter switch
to change the information screen.
Refer to “Information screen (when the ignition switch is
“ON”)” on page 3-161.
CAUTION
!
The S-AWC control mode display may flash under
aggressive driving conditions.
At this time, S-AWC control is temporarily sus-
pended in order to protect the S-AWC device, but
this will not affect normal driving.
After the vehicle is driven for a while, if the S-AWC
control mode display remains on, the S-AWC con-
trol will start operating again.
