WARNING
Always use the utmost care when
driving. Being overconfident be-
cause you are driving a vehicle with
a driver
’
s control center differential
could easily lead to a serious acci-
dent.
CAUTION
.
All the indicators will flash in the
event that the driver
’
s control
center differential has a malfunc-
tion. Have the vehicle inspected
by your SUBARU dealer.
.
When a malfunction exists
—
the
rear differential oil temperature
warning light is illuminating or
the AWD warning light is flash-
ing, there may be the case that all
the indicators will disappear and
the setting of the initial LSD
torque will be cancelled (will
return to the minimum torque).
This, however, is not a malfunc-
tion of the driver
’
s control center
differential itself.
The driver
’
s control center differential
allows you to freely change the degree
of limitation of the differential action
(limited slip differential (LSD) torque) of
your vehicle
’
s center differential.
By using the center differential control
switch, you can set an initial LSD torque to
match the road surface conditions, driving
conditions and your driving style.
1) LSD torque
2) Traction torque
3) Initial LSD torque (maximum)
4) Initial LSD torque (minimum)
A) Initial LSD torque (adjustable)
B) Mechanical LSD torque
The driver
’
s control center differential has
an auto mode and a manual mode. In the
auto mode, the system automatically
adjusts the initial LSD torque. In the
manual mode, you can change to the
desired mode manually by using the
center differential control switch.
NOTE
If you rapidly depress and release the
accelerator pedal while driving at low
speed, you may hear a knocking sound
from the vicinity of the center differen-
