ACD (Active centre differential
system)*
E00611400072
The ACD is a system that improves acceleration per-
formance and straight-ahead stability by regulating
the differential limiting action and power drive dis-
tribution of the centre differential.
CAUTION
l 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 the vehicle in all circum-
stances. Reckless driving may lead to acci-
dents. It is the driver’s responsibility to
drive carefully. This means taking into ac-
count the traffic, road and environmental
conditions.
l Be sure to use tyres that are the same speci-
fied size, type, and brand, and have no dif-
ference in the amount of wear for all four
wheels. Otherwise, the ACD may not
work properly.
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 easier.
ACD control mode
E00625000037
Select the control mode from the following three
types to suit the driving conditions.
ACD control mode Operation
TARMAC
Normally, use this control
mode. Use this mode for
paved roads.
GRAVEL
Use this control mode when
driving on somewhat slip-
pery road surfaces, such as
wet road surfaces and gravel
roads.
SNOW
Use this control mode when
driving on slippery road sur-
faces, such as snow-covered
roads.
ACD control mode switch
E00625100054
When the ignition switch is set to the “ON” posi-
tion, 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
l The control mode can be changed while the
vehicle is moving.
l The selected control mode is stored in memo-
ry even if the engine is stopped.
However, if a battery terminal is disconnec-
ted, the control mode stored in memory will
be erased and the control mode will be set to
the “TARMAC” mode.
ACD control mode display
E00625200101
Example: “TARMAC” mode is selected.
The 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-infor-
mation display.
The control mode display will appear on the infor-
mation screen for a few seconds, and then the origi-
nal screen will return.
