Starting and operating
. 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 “OFF ”position. However, the
initial LSD torque will be minimized
when the battery is disconnected 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 not
indicate 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
light 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 manu-
ally 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.
Automatic transmissionThe automatic transmission is electroni-
cally controlled and provides 4 forward
speeds and 1 reverse speed. Also, it has a
manual mode and a SPORT mode.
WARNING
Do not shift from the “P ” or “N ”
position into the “D ” or “R ” position
while depressing the accelerator
pedal. This may cause the vehicle
to jump forward or backward.
CAUTION
. Shift into the “P ” or “R ” position
only after the vehicle is comple-
tely stopped. Shifting while the
vehicle is moving may cause
damage to the transmission.
. Do not race the engine for more
than 5 seconds in any position
except the “N ” or “P ” position
when the brake is set or when
chocks are used in the wheels.
This may cause the automatic
transmission fluid to overheat.
. Avoid shifting from one of the
forward driving positions into the

Black plate (291,1)
北米Model "A1110BE-C" EDITED: 2010/ 12/ 17
“R ” position or vice versa until
the vehicle has completely
stopped. Such shifting may
cause damage to the transmis-
sion.
. When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the “P ” position. Avoid parking
for a long time with the select
lever in any other position as
doing so could result in a dead
battery.
NOTE. When the engine coolant tempera-
ture is still low, the automatic transmis-
sion will upshift to higher engine
speeds than when the coolant tempera-
ture is sufficiently high in order to
shorten the warm-up time and improve
driveability. The gearshift timing will
automatically shift to the normal timing
after the engine has warmed up.
. Immediately after ATF (automatic
transmission fluid) is replaced, you
may feel that the automatic transmis-
sion operation is somewhat unusual.
This results from invalidation of data
which the on-board computer has
collected and stored in memory to allow the transmission to shift at the
most appropriate times for the current
condition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.

Select lever
: Shifting is possible with the brake pedal
depressed.: Shifting is possible whether the brakepedal is depressed or not. However,
while the ignition switch is in the “LOCK ”
or “Acc ”position, shifting is not possible
if the brake pedal is not depressed.
Depress the brake pedal and move the
select lever.: Shifting is possible whether the brake pedal is depressed or not.
The select lever has four positions, “P”,
“R ”,“N ”, “D ”and also has manual gate for using
“SPORT ”mode or manual mode.
! P (Park)
This position is for parking the vehicle and
starting the engine.
In this position, the transmission is me-
chanically locked to prevent the vehicle
from rolling freely.
When you park the vehicle, first set the
parking brake fully, then shift into the “P ”
position. Do not hold the vehicle with only
the transmission.
To shift the select lever from the “P”to any
other position, you should depress the
brake pedal fully then move the select
lever. This prevents the vehicle from
lurching when it is started.
! R (Reverse)
This position is for backing the vehicle.
To shift from the “N”to “R”position, stop
the vehicle completely then move the
lever to the “R”position.
! N (Neutral)
This position is for restarting a stalled
engine.
In this position the wheels and transmis-
sion are not locked. In this position, the
transmission is neutral; the vehicle will roll
freely, even on the slightest incline unless

Starting and operating
the parking brake or foot brake is applied.
Avoid coasting with the transmission in
neutral.
During coasting, there is no engine brak-
ing effect.
WARNING
Do not drive the vehicle with the
select lever in the “N ” (neutral)
position. Engine braking has no
effect in this condition and the risk
of an accident is consequently in-
creased.NOTEIf the select lever is in the “N ” position
when you stop the engine for parking,
you may not subsequently be able to
move it to the “R ” or “P ” position. If
this happens, turn the ignition switch to
the “ON ”position. You will then be able
to move the select lever to the “P ”
position. For details, refer to “Shift lock
function” F7-24.
! D (Drive)
This position is for normal driving.
The transmission automatically shifts into
a suitable gear from 1st to 4th according to
the vehicle speed and the acceleration
you require. When more acceleration is required in this
position, depress the accelerator pedal
fully to the floor and hold that position. The
transmission will automatically downshift
to 3rd, 2nd or 1st gear. When you release
the pedal, the transmission will return to
the original gear position.
To use the
“SPORT”mode, move the lever
from this position into the manual gate. To
use the manual mode, move the lever
from this position into the manual gate
then move it toward the “+”and “”ends.
! While climbing a grade
When driving up a hill, undesired upshift to
4th gear is prevented from taking place
when the accelerator is released. This
minimizes the chance of subsequent
downshifting to a lower gear when accel-
erating again. This prevents repeated
upshifting and downshifting resulting in a
smoother operation of the vehicle.
NOTEThe transmission may downshift to 2nd
or 1st gear, depending on the way the
accelerator pedal is depressed to ac-
celerate the vehicle again.
! While going down a hill
When you are descending a hill or any
other slope while braking with the
“SPORT ”mode selected, the transmission may downshift to 3rd or 2nd gear depend-
ing on how hard you depress the brake
pedal, causing engine braking to work.
Reacceleration for a short time will cause
the transmission to upshift normally.
NOTE.
A 4th-to-3rd automatic downshift
will not occur at speeds above 50
mph (80 km/h) and a 3rd-to-2nd auto-
matic downshift will not occur at
speeds above 24 mph (38 km/h).
. Automatic downshifts to 3rd or 2nd
may occur even when driving on a level
road depending on conditions, such as
how hard you depress the brake pedal.& Shift lock functionThe shift lock function helps prevent the
improper operation of the select lever.
. The select lever cannot be operated
unless the ignition switch is turned to the
“ ON ”position and the brake pedal is
depressed.
. The select lever cannot be moved from
the “P ” position to any other position
before the brake pedal is depressed.
Depress the brake pedal first, and then
operate the select lever.
. Only the “P ”position allows you to turn
the key from the “Acc”position to the

Starting and operating
. The engine may, on rare occasions,
knock when the vehicle rapidly acceler-
ates or rapidly pulls away from a standstill.
This phenomenon does not indicate a
problem.& SPORT modeSPORT mode is used when power is
needed for rapid acceleration or for uphill
driving. To select this mode, move the
select lever from the “D”position to the
manual gate.
When selected, the SPORT mode indica-
tor light on the combination meter will
illuminate.
To deselect SPORT mode, move the
select lever to the “D”position or select
manual mode.
To subsequently reselect SPORT mode,
move the select lever to the “D”position
and from there to the manual gate.
In this mode, the transmission shifts up at
higher vehicle speeds and shifts down
more responsively than in normal mode.
SI-DRIVE (STI)SI-DRIVE (SUBARU Intelligent Drive)
works to maximize engine performance,
control and efficiency.
This system consists of three modes:
Intelligent (I), Sport (S), and Sport Sharp
(S#). By adjusting the SI-DRIVE selector,
the character of the power unit changes.& Intelligent (I) mode! For smooth, efficient performance
drivingThe Intelligent (I) mode provides well-
balanced performance with greater fuel
efficiency and smooth driveability without
stress. Power delivery is moderate during
acceleration for maximum fuel efficiency.

Black plate (297,1)
北米Model "A1110BE-C" EDITED: 2010/ 12/ 17
This is ideal for around-town driving and
situations that do not require full power
output. It provides better control in difficult
driving conditions, such as slippery roads
or loose surfaces, due to gentler throttle
response.When Intelligent (I) mode is selected, a
shift-up indicator “
”on the combination
meter will blink to signal the best time to
shift gears for maximum fuel efficiency.
& Sport (S) mode! For all-around performance drivingThe Sport (S) mode provides the engine
power desired by those who want to make
the driving experience their own personal
adventure.
The linear acceleration characteristic of
this versatile mode is ideal for normal
driving use.
&Sport Sharp (S#) mode! For maximum performance drivingFor sports-minded drivers, the Sport
Sharp (S#) mode offers an exhilarating
level of engine performance and control.
The throttle becomes more responsive
regardless of the engine speed. Delivering
maximum driving enjoyment, this mode is
ideal for tackling twisting roads and for
merging or overtaking other vehicles on
the freeway with confidence.

Starting and operating
& SI-DRIVE selectorWhen you rotate the SI-DRIVE selector to
the left, the current SI-DRIVE mode
changes to Sport (S) mode. When you
rotate it to the right, the mode changes to
Sport Sharp (S#) mode, and when you
push it, the mode changes to Intelligent (I)
mode. After performing this operation, the
switch returns to its original location.NOTE. The next time you turn on the
engine, after you turned off the engine
in the Sport Sharp (S#) mode, the SI-
DRIVE mode changes to the Sport (S)
mode.
. The next time you turn on the
engine, after you turned off the engine
in the Sport (S) mode or Intelligent (I)
mode, the SI-DRIVE mode will stay in the same mode as when the engine
was turned off.
.
While the engine is running, if the
CHECK ENGINE warning light/malfunc-
tion indicator lamp illuminates, the SI-
DRIVE mode changes to the Sport (S)
mode. In this case, it is not possible to
change to the Sport Sharp (S#) mode or
Intelligent (I) mode.
. If there is a possibility that the
engine could overheat because of a
temperature increase of the engine
coolant, it is not possible to change to
the Sport Sharp (S#) mode. While the
vehicle is in the Sport Sharp (S#) mode,
it changes to the Sport (S) mode when
the engine coolant temperature in-
creases.
. If any of the SI-DRIVE indicators
blink, the SI-DRIVE system may be
malfunctioning. Contact your SUBARU
dealer.
Limited slip differential (LSD)
(STI)The LSD provides optimum distribution of
power according to the difference in
revolutions between the right and left
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads or when high speed
driving.
CAUTION
. Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
. If one tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely
affect the LSD.
. 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 will adversely affect
the LSD.

Rear tie-down hooks:The rear tie-down hooks are located near
each of the jack-up reinforcements.
WARNING
Use the rear tie-down hooks only for
downward anchoring. If they are
used to anchor the vehicle in any
other direction, cables may slip off
the hooks, possibly causing a dan-
gerous situation.
& Using a flat-bed truckThis is the best way to transport your
vehicle. Use the following procedures to
ensure safe transportation.
1. Shift the select lever into the “P ”
position for AT models. Shift the shift lever
into the “1st”position for MT models.
2. Pull up the parking brake lever firmly.
3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out.
CAUTION
If your vehicle has a front under-
spoiler and rear underspoiler (both
optional), be careful not to scrape
them when placing the vehicle on
the carrier and when removing the
vehicle from the carrier.& Towing with all wheels on the
ground1. Release the parking brake and put the
transmission in the “N”/neutral position.
2. The ignition switch should be in the
“Acc ”position while the vehicle is being
towed.
3. Take up slack in the towline slowly to
prevent damage to the vehicle.

In case of emergency
WARNING
. Never turn the ignition switch to
the “LOCK ”position while the
vehicle is being towed because
the steering wheel and the direc-
tion of the wheels will be locked.
. Remember that the brake booster
and power steering do not func-
tion when the engine is not
running. Because the engine is
turned off, it will take greater
effort to operate the brake pedal
and steering wheel.
CAUTION
. If transmission failure occurs,
transport your vehicle on a flat-
bed truck.
. Do not run the engine while being
towed using this method. Trans-
mission damage could result if
the vehicle is towed with the
engine running.
. For models with automatic trans-
mission, the traveling speed
must be limited to less than 20
mph (30 km/h) and the traveling
distance to less than 31 miles (50
km). For greater speeds and distances, transport your vehicle
on a flat-bed truck.
Rear gate
–if the rear gate
cannot be unlockedIn the event that you cannot unlock the
rear gate by operating the power door
locking switches or the remote keyless
entry system, you can unlock it from inside
the cargo area.1. Remove the access cover at the
bottom-center of the rear gate trim.
2. Locate the rear gate lock release lever
behind the rear gate trim panel.
CAUTION
Never operate the rear gate lock
release lever with fingers because
doing so may cause an injury. Al-
ways use a flat-head screwdriver or
