– CONTINUED –Gearshifts can be performed using the se-
lector lever.
Using the selector lever
Shift to the next-higher gear by briefly
pushing the selector lever toward the “+”
end of the manual gate.
Shift to the next-lower gear by briefly pull-
ing the selector lever toward the “–” end of
the manual gate.
NOTE Please read the following points care-
fully and bear them in mind when using
the manual mode.
y The transmission does not automati-
cally shift up in the manual mode. Per-
form gearshifts in accordance with
road conditions so that the tachometer
needle does not enter the red zone. If the engine speed reaches a predeter-
mined level, a fuel-cut function will op-
erate. Shift up if this happens.
y If you attempt to sh ift down when the
engine speed is too high, i.e., when a
downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible.
y If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond.
y You can perform a skip-shift (for ex-
ample, from 4th to 2nd) by operating
the selector lever twice in rapid suc-
cession.
y The transmission automatically se-
lects 1st gear when the vehicle stops
moving.
y If the temperature of the automatic
transmission fluid becomes too high,
the “AT OIL TEMP” warning light will
come on and upshifts to 4th gear will
not be possible. Immediately stop the
vehicle in a safe place and let the en-
gine idle until the warning light goes
off. „ Maximum speeds
The following tables show the maximum
speeds that are possible with each differ-
ent gear.
When down shifting, it is important to con-
firm that the current vehicle speed is not in
excess of the Maximum Allowable Speed
of the gear which is about to be selected.700111
When down shifting, ensure that the
vehicle is not travelling at a speed
exceeding the Maximum Allowable
Speed for the gear which is about to
be selected. Failure to observe this
precaution can lead to engine over-
revving and this in turn can result in
engine damage.
In addition, sudden application of
engine braking caused by down
shifting when the vehicle is travel-
ling on a slippery surface can lead to
wheel locking; as a consequence,
control of the vehicle may be lost
and the risk of an accident in-
creased.

– CONTINUED –To override the shift lock:
1. Set the parking brake and stop the en-
gine.
2. Take out the screwdriver from the tool
bucket.
3. Remove the cover by prying on the
edge with a flat-head screwdriver. 4. Insert the key into the hole.
5. Push down on the screwdriver and
move the selector leve r from the “P” to the
“N” position.
6. Remove the screwdriver from the hole.
Depress the brake pedal and start the en-
gine.
Take your vehicle to the nearest SUBARU
dealer immediately to have the system re-
paired. Automatic transmission – 5-
speed The automatic transmission is electroni-
cally controlled and provides 5 forward
speeds and 1 reverse speed. Also, it has
a manual mode and a SPORT mode.
700346 700347
Do not shift from the “P” or “N” po-
sition into the “D ” or “R” position
while depressing the accelerator
pedal. This may cause the vehicle to
jump forward or backward.
y Shift into the “P” or “R” position
only after the vehic le is complete-
ly stopped. Shifting while the ve-
hicle is moving may cause dam-
age to the transmission.
y Do not race the engine for more
than five 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.

7-18 Starting and operating
NOTE y When the engine coolant tempera-
ture is still low, your vehicle’s automat-
ic transmission will up-shift at higher
engine speeds than when the coolant
temperature is sufficiently high in or-
der to shorten the warm-up time and
improve driveability. The gearshift tim-
ing will automatically shift to the nor-
mal timing after the engine has warmed
up.
y 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 col-
lected and stored in memory to allow the transmission to shift at the most
appropriate times for the current con-
dition of your vehicle. Optimized shift-
ing will be restored as the vehicle con-
tinues to be driven for a while.
„ Selector lever
: Shift possible with brake pedal de-
pressed
: Shift possible with brake pedal not
depressed
The selector lever has four positions, “P”,
“R”, “N”, “D” and also has manual gate for
using “SPORT” mode or manual mode.
T 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 selector lever from the “P” to
any other position, you should depress the
brake pedal fully then move the selector
lever. This prevents the vehicle from
lurching when it is started.
NOTE (3.0-liter models only) To protect the engine while the “P” po-
sition is selected, the engine is con-
trolled such that the engine speed
does not become too high even if the
accelerator pedal is pressed hard.
T R (Reverse)
This position is for backing the vehicle.
To shift from the “N” to “R” position, stop
the vehicle completely then move the le-
ver to the “R” position.
T N (Neutral)
This position is for restarting a stalled en-
gine.
In this position the wheels and transmis-
sion are not locked. In this position, they Avoid shifting from one of the for-
ward driving positions into the
“R” position or vice versa until the
vehicle has completely stopped.
Such shifting may cause damage
to the transmission.
y When parking the vehicle, first se-
curely apply the parking brake
and then place the selector lever
in the “P” position. Avoid parking
for a long time with the selector le-
ver in any other position as doing
so could result in a dead battery. 700107

Starting and operating

– CONTINUED –transmission is neutral; the vehicle will roll
freely, even on the slightest incline unless
the parking brake or foot brake is on.
Avoid coasting with the transmission neu-
tral.
During coasting, there is no engine brak-
ing effect.
NOTE (3.0-liter models only) To protect the engine while the “N” po-
sition is selected, the engine is con-
trolled such that the engine speed
does not become too high even if the
accelerator pedal is pressed hard.
NOTE If the selector lever is in the “N” posi-
tion when you stop the engine for park-
ing, you may not subsequently be able
to move it to the “R” and “P” positions.
If this happens, turn the ignition switch
to the “ON” position. You will then be
able to move the selector lever to the
“P” position. T D (Drive)
This position is for normal driving.
The transmission automatically shifts into
a suitable gear from 1st to 5th according to
the vehicle speed and the acceleration
you require.
When more acceleration is required in this
position, press the accelerator pedal fully
to the floor and hold that position. The
transmission will automatically downshift
to 4th, 3rd, 2nd or 1st gear. When you re-
lease the pedal, the transmission will re-
turn 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.
V While climbing a grade
When driving up a hill, undesired upshift to
4th or 5th 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 up-
shifting and downshifting resulting in a
smoother operation of the vehicle.
NOTE The transmission may downshift to
2nd or 1st gear, depending on the way the accelerator pedal is pressed to ac-
celerate the vehicle again.
V While going down a hill
When you are descending a hill or any
other slope while braking with the
“SPORT” mode selected, the transmis-
sion may downshift to 4th or 3rd gear de-
pending on how hard you depress the
brake pedal, causing engine braking to
work. Reacceleration for a short time will
cause the transmission to upshift normal-
ly.
NOTE y A 5th-to-4th automa tic downshift will
not occur at speeds above 78 mph (126
km/h) and a 4th-to-3rd automatic down-
shift will not occur at speeds above 53
mph (86 km/h).
y Automatic down shifts to 4th or 3rd
may occur even when driving on a level
road depending on conditions, such as
how hard you depress the brake pedal.
„ Selector lever reverse inhibit-
ing function This function prevents accidental move-
ment of the selector lever to the “R” posi-
tion while the vehicle is moving.
The function becomes operational when
the vehicle reaches a speed of approxi-Do not drive the vehicle with the se-
lector lever in the “N” (neutral) posi-
tion. Engine braking has no effect in
this condition and the risk of an ac-
cident is consequently increased.

7-20 Starting and operating
mately 6 mph (10 km/h). Once operation-
al, it prevents the selector lever from being
moved from the “N” position to the “R” po-
sition. When the vehicle speed drops be-
low 6 mph (10 km/h), the function is can-
celed. The selector lever can then be
moved to the “R” and “P” positions.
When the ignition switch has been turned
to the “OFF” position, movement of the se-
lector lever from the “N” position to the “R”
position is possible for a limited time peri-
od and then becomes impossible. Also,
the selector lever cannot be moved to the
“R” position when it has been placed in the
“P” position and then placed again in the
“N” position. When movement of the se-
lector lever from the “N” position to the “R”
position has become impossible, turn the
ignition switch back to the “ON” position
then move the selector lever to the “P” po-
sition. Pressing the se lector lever release
button also makes it possible to move the
selector lever to the “P” position at this
time. T Selector lever release button
If you inadvertently have turned the igni-
tion switch to the “OFF” position with the
selector lever in the “N” position, proceed
as follows. By referring to the “Shift lock
release” section in this chapter, remove
the shift lock release cover. Then, with the
screwdriver inserted into the hole, move
the selector lever to the “P” position. If the
selector lever reverse inhibiting function
fails, have the vehicle inspected by the
nearest SUBARU dealer. „ Selection of manual mode
With the vehicle either moving or station-
ary, move the selector lever from the “D”
position to the manual gate then move it to
the “+” end or “–” end of the manual gate
to select manual mode. 700345

7-22 Starting and operating
transmission will automatically switch
back from manual mode to normal mode.
NOTE Please read the following points care-
fully and bear them in mind when using
the manual mode.
y When the temperature of the auto-
matic transmission fluid is higher than
normal, warning beeps are emitted and
the shift position in dicator shows “–”.
If these warnings are issued, deselect
the manual mode to protect the auto-
matic transmission from damage.
y When the temperature of the engine
oil is higher than normal, warning
beeps are emitted and the shift posi-
tion indicator shows “–”. If these warn-
ings are issued, deselect the manual
mode to protect th e engine from dam-
age. (3.0-liter models only)
y The transmission does not automati-
cally shift up in the manual mode. Per-
form gearshifts in accordance with
road conditions so that the tachometer
needle does not enter the red zone. If
the engine speed reaches a predeter-
mined level, a fuel-cut function will op-
erate. Shift up if this happens. (Also, in
the case of a 3.0-liter model, the trans-
mission may automatically shift up to
protect the engine.)
y If you attempt to shift down when the engine speed is too high, i.e., when a
downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible.
y If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond.
y You can perform a skip-shift (for ex-
ample, from 4th to 2nd) by operating
the selector lever or a steering-wheel
switch twice in rapid succession.
y The transmission automatically se-
lects 1st gear when the vehicle stops
moving.
y If the temperature of the automatic
transmission fluid becomes too high,
the “AT OIL TEMP” warning light will
come on and upshifts to 5th gear will
not be possible. Immediately stop the
vehicle in a safe place and let the en-
gine idle until the warning light goes
off. „ Maximum speeds
The following tables show the maximum
speeds that are possible with each differ-
ent gear.
When down shifting, it is important to con-
firm that the current vehicle speed is not in
excess of the Maximum Allowable Speed
of the gear which is about to be selected. When down shifting, ensure that the
vehicle is not travelling at a speed
exceeding the Maximum Allowable
Speed for the gear which is about to
be selected. Failure to observe this
precaution can lead to engine over-
revving and this in turn can result in
engine damage.
In addition, sudden application of
engine braking caused by down
shifting when the vehicle is travel-
ling on a slippery surface can lead to
wheel locking; as a consequence,
control of the vehicle may be lost
and the risk of an accident in-
creased.

7-32 Starting and operating
tems.
Because the Vehicle Dynamics Control
system controls each brake through the
ABS, whenever the ABS stops operating
due to a malfunction in that electrical sys-
tem, the Vehicle Dynamics Control will
also become unable to control all four
brakes. Thus Vehicle Dynamics Control
system operation halt s and the warning
light turns on. Although both the Vehicle
Dynamics Control system and the ABS
will be inoperable in this situation, it will
still be possible to stop the vehicle using
normal braking. The Vehicle Dynamics
Control system and the ABS do not ad-
versely affect operation of the vehicle in
any way when they are inoperable; how-
ever should such a situation occur, drive
with care and have an authorized
SUBARU dealer carry out an inspection of
those systems at the first available oppor-
tunity.
NOTE When the warning light turns on and
off in the following way, it indicates
that the Vehicle Dynamics Control sys-
tem is operating normally.
y Although turning on after the engine
has been started, the warning light
quickly turns off and stays off.
y The warning light turns on when the vehicle is being driven; it then turns off
and stays off.
V Vehicle Dynamics Control OFF indi-
cator light
This light comes on to indicate that the Ve-
hicle Dynamics Control system is in non-
operation mode. This does not constitute
failure of the Vehicle Dynamics Control
system.
NOTE y The indicator light may stay on for a
while after the engine has been started,
especially in cold weather. This occurs
because the engine has not yet
warmed up and is completely normal.
The light will turn off when the engine
has reached a suitable operating tem-
perature.
y When an engine problem occurs and
the malfunction indicator lamp turns
on, the indicator light will also come
on.
The following two situations could indicate
malfunction of the Vehicle Dynamics Con-
trol system; if either should occur, have an
authorized SUBARU dealer carry out an
inspection of that syst em at the first avail-
able opportunity.
y The indicator light does not turn on
when the ignition switch is turned to the ON position.
y The indicator light fail s to turn off after
the engine is started, even when several
minutes have passed to allow the engine
to heat up sufficiently.
„ Vehicle Dynamics Control
OFF switch
Pressing the switch to deactivate the Ve-
hicle Dynamics Contro l system can facili-
tate the following operations:

road with a snowy, grav el-covered, or oth-
erwise slippery surface
y extrication of the vehicle when its
wheels are stuck in mud or deep snow
When the switch is pressed during engine
operation, the indicator light illuminates. 700114

Driving tips

– CONTINUED –T OUTBACK models only Your vehicle is equipped with “all season
tires” which are designed to provide an
adequate measure of traction, handling
and braking performance in year-round
driving. In winter, it may be possible to en-
hance performance through use of tires
designed specifically for winter driving
conditions.
If you choose to install winter tires on your
vehicle, be sure to use the correct tire size
and type. You must install four winter tires
that are of the same size, construction,
brand and load range and you should nev-
er mix radial, belted bias or bias tires since
this may result in dangerous handling
characteristics. When you choose a tire,
make sure that there is enough clearance
between the tire and vehicle body.
Remember to drive with care at all times
regardless of the type of tires on your ve-
hicle.
Your OUTBACK comes with P225/
55R17 “all season tires” as original
equipment. You should be aware that
some winter tires with that same size
designation may actually be too large
for the vehicle and may cause rubbing
on sharp turns. Listed in the following
is the winter tire size that we recom-
mend. Recommended winter (snow) tire size
OUTBACK models: P215/55R17,
P225/60R16 or P215/60R16 Studless
„ Tire chains
Driving on snowy grades or icy roads mayy When replacing original tires with
winter (snow) tires, make sure you
use only the same size and con-
struction as recommended. Using
other sizes or construction may
affect speedometer/odometer cal-
ibration and clearance between
the body and tires. It also may be
dangerous and lead to loss of ve-
hicle control.
y You must install four winter tires
that are of the same size, circum-
ferences, construction, brand,
and load range. Mixing other siz-
es, circumferences or construc-
tions may result in severe me-
chanical damage to the drive train
of your vehicle and may affect
ride, handling, braking and speed-
ometer/odometer calibration. It
also may be dangerous and lead
to loss of vehicle control.
y Do not use a combination of radi-
al, belted bias or bias tires since it
may cause dangerous handling
characteristics and lead to an ac-
cident. Tire chains cannot be used on tires
listed in the following because of
lack of clearance between the tires
and vehicle body.

11 - 1 2 Maintenance and service
Oil capacity (Guideline):
2.5-liter models: 4.2 US qt (4.0 liters, 3.5
Imp qt)
3.0-liter models: 5.8 US qt (5.5 liters, 4.8
Imp qt)
The oil quantity indicated above is only a
guideline. The necessary quantity of oil
depends on the quantity of oil that has
been drained. The quantity of drained oil
differs slightly depen ding on the tempera-
ture of the oil and the time the oil is left
flowing out. After refilling the engine with
oil, therefore, you must use the dipstick to
confirm that the level is correct.
13.Start the engine and make sure that no
oil leaks appear around the filter’s rubber
seal and drain plug.
14.Run the engine until it reaches the nor-
mal operating temperature. Then stop the
engine and wait a few minutes to allow the
oil drain back. Check the oil level again
and if necessary, add more engine oil.
„ Recommended grade and
viscosity Oil grade:
ILSAC GF-4, which can be identified
with the ILSAC certification mark
(Starburst mark)
or API classification SM with the
words “ENERGY CONSERVING”
These recommended oil grades can be
identified by looking for either or both of
the following marks displayed on the oil
container.
ILSAC Certification Mark (Starburst
Mark) API Service label
1) Indicates the oil quality by API designa-
tions
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving ca-
pabilities
In choosing an oil, you want the proper
quality and viscosity, as well as one that
will add to fuel economy. The following ta-
ble lists the recommended viscosities and
applicable temperatures.
When adding oil, different brands may be
used together as long as they are the
same API classifica tion and SAE viscosity
as those recommended by SUBARU.
Use only engine oil with the recom-
mended grade and viscosity. B00014
