Safety precautions when
driving&Seatbelt and SRS airbag
WARNING
.All persons in the vehicle must
fasten their seatbelts BEFORE
the vehicle starts to move. Other-
wise, the possibility of serious
injury becomes greater in the
event of a sudden stop or acci-
dent.
.To obtain maximum protection in
the event of an accident, the
driver and all passengers must
always wear seatbelts when in
the vehicle. The SRS (Supple-
mental Restraint System) airbag
does not do away with the need to
fasten seatbelts. In combination
with the seatbelts, it offers the
best combined protection in case
of a serious accident.
Not wearing a seatbelt increases
the chance of severe injury or
death in a crash even when the
vehicle has the SRS airbag.

NOTE.After replacing or adding the engine
oil, if the engine oil level is within the
normal range when restarting the en-
gine on a level surface, the warning
indicator will be off.
.The warning indicator may appear
temporarily in the following conditions
because a low oil level may be detected
as a result of significant oil movement
in the engine.
–when the vehicle is considerably
inclined on an uphill or steep slope
–when the vehicle has continu-
ously accelerated and decelerated
–when the vehicle is continuously
turned
–when the vehicle is driven on a
road that alternates continuously
between uphill and downhill&Windshield washer
fluid warning indicatorThis indicator appears when the fluid level
in the windshield washer fluid tank de-
creases to the lower limit (approximately
1.1 US qt, 1.0 liter, 0.9 Imp qt).
&AT OIL TEMP warning
light (CVT models)If this light illuminates when the engine is
running, it may indicate that the transmis-
sion fluid temperature is too hot.
If the light illuminates while driving, im-
mediately stop the vehicle in a safe place
and let the engine idle until the warning
light turns off.
!Transmission control system warn-
ing
If the“AT OIL TEMP”warning light flashes
after the engine has started, it may indicate
that the transmission control system is not
working properly. Contact your nearest
SUBARU dealer for service immediately.&Rear differential oil
temperature warning
light (STI)
CAUTION
If the R.DIFF TEMP warning light
illuminates, reduce vehicle speed
and stop the vehicle in a safe loca-
tion as soon as possible. Continuing
to drive with this light illuminated
may damage the rear differential and
other parts of the powertrain.If this light illuminates when the engine is
running, it may indicate that the rear
differential oil temperature is too hot.
At this time, the driver’s control center
differential will automatically cancel the
current torque-distribution ratio setting and
adopt its minimum ratio.
If the light illuminates while driving, reduce
vehicle speed and stop the vehicle in the
nearest safe location. Park the vehicle for
several minutes. After the light turns off,
you can start driving.
If the light does not turn off, contact the
nearest SUBARU dealer for service.
NOTE.If the tire pressures are not correct
and/or the tires are not all the same size
and brand, the rear differential will be
heavily loaded when the vehicle is
driven, resulting in an abnormally high
oil temperature.
.The rear differential oil will deterio-
rate if its temperature increases en-
ough for the rear differential oil tem-
perature warning light to illuminate. It is
advisable to have the rear differential
oil replaced as soon as possible.

Continuously variable trans-
missionThe continuously variable transmission is
electronically controlled and provides an
infinite number of forward speeds and 1
reverse speed. It also has a manual 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
.Observe the following precau-
tions. Otherwise, the transmis-
sion could be damaged.
–Shift into the“P”or“R”posi-
tion only after the vehicle has
completely stopped.
–Do not shift from the“D”
position into the“R”position
or vice versa until the vehicle
has completely stopped.
.Do not race the engine for more
than 5 seconds in any position
except the“N”or“P”positionwhen the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
.Never move the vehicle as fol-
lows. Doing so may result in an
unexpected accident or malfunc-
tion.
–Moving rearward by inertia
with the select lever set in a
forward driving position.
–Moving forward by inertia with
the select lever set in the“R”
position.
.When parking the vehicle, first
securely apply the parking brake
and then place the select lever in
the“P”position. Do not park 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 transmission will
upshift to higher engine speeds than
when the coolant temperature is suffi-
ciently high in order to shorten the
warm-up time and improve driveability.
The gearshift timing will automaticallyshift to the normal timing after the
engine has warmed up.
.Immediately after transmission fluid
is replaced, you may feel that the
transmission 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.
.When driving under continuous hea-
vy load conditions such as when climb-
ing a long, steep hill, the engine speed
or the vehicle speed may automatically
be reduced. This is not a malfunction.
This phenomenon results from the
engine control function maintaining
the cooling performance of the vehicle.
The engine and vehicle speed will
return to a normal speed when the
engine is able to maintain the optimum
cooling performance after the heavy
load decreases. Take extremely care
when driving under a heavy load.
.The continuously variable transmis-
sion is a chain type system that pro-
vides superior transmission efficiency
for maximum fuel economy. At times,
depending on varying driving condi-
tions, a chain operating noise may be

!N (Neutral)
This position is for restarting a stalled
engine. In this position, the transmission is
neutral, meaning that the wheels and
transmission are not locked. Therefore,
the vehicle will roll freely, even on the
slightest incline unless the parking brake
or foot brake is applied.
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”and“P”positions. 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.!D (Drive)
This position is for normal driving. The
transmission shifts automatically and con-
tinuously into a suitable gear according to
the vehicle speed and the acceleration you
require. Also, while driving up and down a
hill, the transmission assists and controls
the driving performance and engine brak-
ing while corresponding to the road grade.
When more acceleration is required in the
“D”position, depress the accelerator pedal
fully to the floor and hold that position. The
transmission will automatically downshift.
If the Intelligent (I) mode or the Sport (S)
mode has been selected, the transmission
will operate like a conventional automatic
transmission. When you release the pedal,
the transmission will return to the original
gear position.
If you operate one of the shift paddles
behind the steering wheel while driving in
the“D”position, the transmission will
temporarily switch to the manual mode.
In this mode, you can shift into any gear
position using the shift paddles. For details
about the manual mode, refer to“Selection
of manual mode”F7-25. Once the vehicle
speed stabilizes, the transmission will
switch from the manual mode back to the
“D”position for normal driving.
&Selection of manual modeWith the vehicle either moving or station-
ary, move the select lever from the“D”
position to the“M”position to select the
manual mode.

1) Upshift indicator
2) Downshift indicator
3) Gear position indicatorWhen the manual mode is selected, the
gear position indicator and upshift indica-
tor and/or downshift indicator on the
combination meter appear.
The gear position indicator shows the
currently selected gear in the following
range.
.1st-to-8th-gear range (when the Sport
Sharp (S#) mode is selected)
.1st-to-6th-gear range (in other situa-
tions)
The upshift and downshift indicators show
when a gear shift is possible. When the
upshift indicator“
”appears, upshifting is
possible. When the downshift indicator“
”appears, downshifting is possible.
When both indicators appear, upshifting
and downshifting are both possible. When
the vehicle stops (for example, at traffic
signals), the downshift indicator turns off.
Gearshifts can be performed using the
shift paddle behind the steering wheel.
To upshift to the next higher gear position,
pull the shift paddle that has“+”indicated
on it. To downshift to the next lower gear
position, pull the shift paddle that has“–”
indicated on it.
CAUTION
Do not place or hang anything on the
shift paddles. Doing so may result in
accidental gear shifting.
NOTEPlease read the following points care-
fully and bear them in mind when using
the manual mode.
.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.
.If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond.
.You can perform a skip-shift (for
example, from 4th to 2nd) by operating
the shift paddle twice in rapid succes-
sion.
.The transmission automatically se-
lects 1st gear when the vehicle stops
moving.
.If the temperature of the transmis-
sion fluid becomes too high, the“AT
OIL TEMP”warning light on the combi-
nation meter will illuminate. Immedi-
ately stop the vehicle in a safe location
and let the engine idle until the warning
light turns off.
.By selecting the Sport Sharp (S#)
mode, upshifting will not occur auto-
matically. According to the road condi-
tions, shift change manually so that the
tachometer needle does not enter the

!Except STI
When you select the Sport Sharp (S#)
mode with the select lever in the“D”
position, the transmission gear ratio will
shift from variable speed to eight-speed.
The select lever/gear position indicator
display will change from“D”to the gear
position.
When selecting Sport Sharp (S#) mode,
the following controls will be applied.
.Uphill control
Prevents unnecessary shift-up/shift-down
during ascent.
.Cornering control
While turning, if there is a large centrifugal
force, shift-up will not occur: during re-
acceleration.
.Braking control
At the beginning of corners etc., heavy
application of the brake pedal will cause
automatic downshift and gently re-accel-
erate.
.Sudden acceleration return control
During acceleration, if acceleration pedal
is returned suddenly (for example, at
corners etc.), shift-up will not be applied.
&SI-DRIVE switch
NOTE.The next time you turn on the engine,
the following SI-DRIVE mode will be
selected.
–Intelligent (I) mode if you have
turned off the engine in the Intelli-
gent (I) mode
–Sport (S) mode if you have turned
off the engine in the Sport (S) mode
or Sport Sharp (S#) mode
.If the CHECK ENGINE warning light/
malfunction indicator light illuminates
during engine operation, 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 the engine coolant temperature
becomes so high that the engine could
overheat, 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.!STI
