&Auto modeIn the auto mode, the system estimates the
driving and road conditions using signals
from the wheel speed sensor, throttle
position sensor, steering angle sensor
and brake switch, etc. According to the
result, it electronically and automatically
controls the degree of limitation of the
differential action (LSD torque) to optimize
the differential action of the center differ-
ential. When you turn the ignition switch
ON, the“AUTO”indicator on the combina-
tion meter appears.The auto mode has 3 modes as follows.
Mode Operation
AUTO [+] This mode emphasizes traction
control and strengthens the lim-
itation of differential action that
is suitable for driving on slippery
roads for vehicle stability.
AUTO This mode is suitable for most
driving situations.
AUTO [] This mode is suitable when you
seek quick response from the
steering wheel and smooth
driving.
!Mode setting method
In most situations, it is recommended that
the“AUTO”mode is selected.Push the control switch forward to select
the“AUTO [+]”mode. After setting themode,“AUTO [+]”appears.
Pull the control switch rearward to select
the“AUTO []”mode. After setting the
mode,“AUTO []”appears.
When the“AUTO [+]”mode is selected,
pull the control switch rearward to change
to the“AUTO”mode. When the“AUTO []”
mode is set, push the control switch
forward to change to the“AUTO”mode.

Pull the switch rearward to reduce the
initial LSD torque. When the lowest posi-
tion of the driver’s control center differen-
tial indicator is displayed, the initial LSD
torque will be minimum.
CAUTION
.Do not operate the control switch
when a wheel slippage occurs.
Wait until the wheelspin has been
brought under control.
.Under any of the following condi-
tions after setting to the manual
mode, pull the center differential
control switch to minimize the
initial LSD torque:
–When a temporary spare tire is
installed–When your vehicle is towed
–When the vehicle is stopped
with the manual mode se-
lected
NOTE.A higher initial LSD torque setting
gives the vehicle greater traction when
driving straight ahead but makes cor-
nering more difficult. Remember this
when adjusting the initial LSD torque.
In general, higher initial LSD torque
settings assist driving on slippery
roads and lower settings for non-slip-
pery roads. When the vehicle is stuck in
snow or mud, setting the initial LSD
torque to the maximum will help to free
the vehicle.
.The setting of the initial LSD torque
will remain even when the auto mode is
selected or the ignition switch is turned
to the“LOCK”/“OFF”position. How-
ever, the initial LSD torque will be
minimized when the battery is discon-
nected and reconnected.
.During cornering or when making
turns (especially when going into the
garage), the rotational difference be-
tween the front and rear wheels may
cause a braking effect accompanied by
vibration and noise. This does notindicate a problem. The phenomenon
will disappear when setting the initial
LSD torque to the minimum.
In the auto mode, it controls the initial
LSD torque automatically. While in the
auto mode, this phenomenon some-
times occurs depending on the driving
condition, however, it does not indicate
a problem.
.Use the center differential indicator
only as a rough indication of the initial
LSD torque.
.If you operate the center differential
control switch while quickly accelerat-
ing or turning a tight corner, you may
feel slight shocks. This is due to
differential action by the center differ-
ential and does not indicate a problem.
&Temporary releaseWhen the driver stops the vehicle and pulls
the parking brake lever after manually
setting the initial LSD torque, the LSD
torque is temporarily minimized. However
the indicator on the combination meter
continues to show the driver’s selected
initial LSD torque. When the driver re-
leases the parking brake lever, the initial
LSD torque set by the driver is restored.

should be taken into account
when driving the vehicle in
such a condition.
.If you use non-matching tires, the
Vehicle Dynamics Control sys-
tem may not operate correctly.
.The Vehicle Dynamics Control
system helps prevent unstable
vehicle motion such as skidding
using control of the brakes and
engine power. Do not turn off the
Vehicle Dynamics Control sys-
tem unless it is absolutely neces-
sary. If you must turn off the
Vehicle Dynamics Control sys-
tem, drive very carefully accord-
ing to the road surface condition.
In the event of wheelspin and/or skidding
on a slippery road surface and/or during
cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system
adjusts the engine’s output and the
wheels’respective braking forces to help
maintain traction and directional control.
.Traction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown byflashing the Vehicle Dynamics Control
operation indicator light.
.Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels’tendency to slide
sideways during steering operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light.
Vehicle Dynamics Control operation indi-
cator lightNOTE.The Vehicle Dynamics Control sys-
tem may be considered normal when
the following conditions occur.
–Slight twitching of the brakepedal is felt.
–The vehicle or steering wheel
shakes to a small degree.
–An operating sound from the
engine compartment is heard briefly
when starting the engine and when
driving off after starting the engine.
–The brake pedal seems to jolt
when driving off after starting the
engine.
.In the circumstances shown in the
following list, the vehicle may be less
stable than it feels to the driver. The
Vehicle Dynamics Control System may
therefore operate. Such operation does
not indicate a system malfunction.
–on gravel-covered or rutted roads
–on unfinished roads
–when the vehicle is fitted with
snow tires or winter tires
.Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheelto feel slightly
different compared to that for normal
conditions.
.It is always important to reduce
speed when approaching a corner,
even if your vehicle is equipped with
the Vehicle Dynamics Control system.
.Always turn off the engine before
replacing a tire. Failure to do so may
render the Vehicle Dynamics Control

!Vehicle Dynamics Control mode
When the ignition switch is on, this mode is
selected first.
This mode enables all controls for ABS,
the Traction Control System, and the
Vehicle Dynamics Control system. Select
this mode for most driving situations.
When this mode is selected, both indicator
lights on the combination meter turn off.!Traction mode
This mode restricts the functions of the
Traction Control System and Vehicle Dy-
namics Control system and thus delays
utilizing their functions as a reaction to
vehicle behavior in comparison with the
Vehicle Dynamics Control mode. Use this
mode in driving situations where the
vehicle dynamic performance will improve
without decreasing engine torque control.
When you press the switch briefly during
engine operation, the traction mode in-
dicator light and the Vehicle Dynamics

nation meter illuminate. When you press
the switch again to reactivate the Vehicle
Dynamics Control system, the traction

Driving tips for AWD models
WARNING
.Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden brak-
ing or under other similar condi-
tions.
.Always use the utmost care in
driving–overconfidence be-
cause you are driving an All-
Wheel Drive vehicle could easily
lead to a serious accident.
.When you replacing or installing
tire(s), all four tires must be the
same for following items.
(a) Size
(b) Circumference
(c) Speed symbol
(d) Load index
(e) Construction
(f) Manufacturer
(g) Brand (tread pattern)
(h) Degrees of wear
For the items (a) to (d), you must
obey the specification that isprinted on the tire placard. The
tire placard is located on the
bottom of driver’s door pillar.
If all of four tires are not the same
for items (a) to (h), there is a
possibility that serious mechan-
ical damage could occur to the
drive train of your car, and affect
the following.
—Ride
—Handling
—Braking
—Speedometer/Odometer
calibration
—Clearance between the body
and tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
CAUTION
If you use a temporary spare tire to
replace a flat tire, be sure to use the
original temporary spare tire stored
in the vehicle. Using other sizes may
result in severe mechanical damage
to the drive train of your vehicle.
All-Wheel Drive distributes the engine
power to all four wheels. AWD models
provide better traction when driving on
slippery, wet or snow-covered roads and
when moving out of mud, dirt and sand. By
shifting power between the front and rear
wheels, SUBARU AWD can also provide
added traction during acceleration and
added engine braking force during decel-
eration.
Therefore, your SUBARU AWD vehicle
may handle differently than an ordinary
two wheel drive vehicle and it contains
some features unique to AWD. For safety
purposes as well as to avoid damaging the
AWD system, you should keep the follow-
ing tips in mind.
.An AWD model is better able to climb
steeper roads under snowy or slippery
