The driver’s control center differential al-
lows you to freely change the degree of
limitation of the differential action (limited
slip differential (LSD) torque) of your vehi-
cle ’s center differential.
By using the center differential control di-
al, 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
A) Initial LSD torque (adjustable)
B) Mechanical LSD torque
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-
tial and rear differential. This sound oc-
curs because of the structure of the
center differential. It does not indicate
a problem.
Auto mode
In the auto mode, the system estimates
the driving and road conditions using sig-
nals from the wheel speed sensor, throttle
position sensor, steering angle sensor
and brake switch, etc. According to the re-
sult, it electronically and automatically
controls the degree of limitation of the dif-
ferential action (LSD torque) to optimize
the differential action of the center differ-
ential. When the ignition switch is turned
ON, the “AUTO ” indicator light in the com-
bination meter comes on. The system can
be switched to a manual mode.
Manual mode
In the manual mode, you can use the cen-
ter differential control dial to adjust the ini-
In the event of failure of the driver
’s
control center differential, the “ ”
indicator light will flash. Have the
vehicle inspected by your SUBARU
dealer.

with plenty of lukewarm water. Wipe the
remaining water off with a chamois or soft
cloth.
Washing the underbody
Chemicals, salts and gravel used for deic-
ing road surfaces are extremely corrosive,
accelerating the corrosion of underbody
components, such as the exhaust system,
fuel and brake lines, brake cables, floor
pan and fenders, and suspension.
Thoroughly flush the underbody and in-
side of the fenders with lukewarm or cold
water at frequent intervals to reduce the
harmful effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-
sion.
After driving off-road or on muddy or
sandy roads, wash the mud and sand off
the underbody. Carefully flush the sus-
pension and axle parts, as they are partic-
ularly prone to mud and sand buildup. Do
not use a sharp-edged tool to remove
caked mud.
NOTE
Be careful not to damage brake hoses,
sensor harnesses, and other parts
when washing suspension compo-
nents.
Using a warm water washer
Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle.
Do not wash the same area continuous-
ly.
If a stain will not come out easily, wash
by hand. Some warm water washers are
of the high temperature, high pressure
type, and they can damage or deform the
resin parts such as mouldings, or cause
water to leak into the vehicle.
Waxing and polishing
Always wash and dry the vehicle before
waxing and polishing.
Use a good quality polish and wax and ap-
ply them according to the manufacturer ’s
instructions. Wax or polish when the paint-
ed surface is cool.
Be sure to polish and wax the chrome trim,
as well as the painted surfaces. Loss of
wax on a painted surface leads to loss of
the original luster and also quickens the
deterioration of the surface. It is recom-
mended that a coat of wax be applied at
least once a month, or whenever the sur-
face no longer repels water.
If the appearance of the paint has dimin-
ished to the point where the luster or tone cannot be restored, lightly polish the sur-
face with a fine-grained compound. Never
polish just the affected area, but include
the surrounding area as well. Always pol-
ish in only one direction. A No. 2000 grain
compound is recommended. Never use a
coarse-grained compound. Coarser
grained compounds have a smaller grain-
size number and could damage the paint.
After polishing with a compound, coat with
wax to restore the original luster. Frequent
polishing with a compound or an incorrect
polishing technique will result in removing
the paint layer and exposing the under-
coat. When in doubt, it is always best to
contact your SUBARU dealer or an auto
paint specialist.
NOTE
Be careful not to block the windshield
washer nozzles with wax when waxing
the vehicle.
Cleaning aluminum wheels
Promptly wipe the aluminum wheels
clean of any kind of grime or agent. If dirt
is left on too long, it may be difficult to
clean off.
Do not use soap containing grit to clean
the wheels. Be sure to use a neutral clean-
ing agent, and later rinse thoroughly with
water. Do not clean the wheels with a stiff
