S-AWC (Super-All Wheel
Control)
E00622600032
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 (Active centre differential
system), the AYC (Active yaw control system), the
anti-lock brake system (ABS) and the Active Sta-
bility Control (ASC).
Please read this section in conjunction with the fol-
lowing sections.

CAUTION
l
Do not over-rely on the S-AWC. Even the
S-AWC 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 the vehicle in all
circumstances. Reckless driving may lead
to accidents. It is the driver’s responsibil-
ity to drive carefully. This means taking
into account the traffic, road and envi-
ronmental conditions.
CAUTION
l
Be sure to use tyres 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 centre differential sys-
tem)
E00622700033
The ACD is a system that improves acceleration
performance and straight-ahead stability by regu-
lating the differential limiting action and power
drive distribution of the centre differential.
NOTE
l
If the parking brake lever is pulled up while
the vehicle is moving, the centre differential
is designed to switch to a free state condition
which will allow the rear wheel to lock eas-
ier.
AYC (Active yaw control system)
E00622800034
The AYC is a system, with a left-right differential
limiting function and yaw control function, that en-
hances 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.
CAUTION
l
Control of the braking force does not en-
hance the stopping performance of the
vehicle, therefore, pay careful attention
to the safety of your surroundings when
driving.
Left-right differential limiting function
The left-right differential limiting function is a
function that enhances driving performance and ve-
hicle stability by preventing idle spinning of a
wheel when driving on slippery road surfaces or
when the road surfaces of the left and right wheels
are different.
Yaw control function
The yaw control function is a function that enhan-
ces vehicle cornering performance by controlling
the drive power difference 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 driv-
ing on slippery road surfaces.
S-AWC control mode
E00623000121
Select the control mode from the following three
types to suit the driving conditions.
S-AWC control

Normally, use this control
mode. Use this mode for
paved roads.
