Seat heater (if equipped)The front seats are equipped with a seat
heater.
The seat heater operates when the ignition
switch is either in the“ACC”or“ON”
position.
CAUTION
.People with delicate skin may
suffer slight burns even at low
temperatures if they use the seat
heater for a long period of time.
When using the heater, always be
sure to warn the persons con-
cerned.
.Do not put anything on the seat
which insulates against heat,
such as a blanket, cushion, or
similar items. This may cause the
seat heater to overheat.
.When the seat is warmed enough
or before you leave the vehicle,
be sure to turn off the seat heater.NOTEUse of the seat heater for a long period
of time while the engine is not running
can cause battery discharge.
Type AType B
1)HIGH (HI)–Rapid heating
2)LOW (LO)–Normal heating
3) Off
A) Left-hand side
B) Right-hand sideTo turn on the seat heater, push the“LOW”
(“LO”)or“HIGH”(“HI”) position on the
switch, as desired, depending on the
temperature.
Selecting the“HIGH”(“HI”) position will
cause the seat to heat up quicker.
To turn off the seat heater, lightly press the
opposite side of the current position.
The indicator located on the switch illumi-
nates when the seat heater is in operation.
When the seat is warmed enough or
before you leave the vehicle, be sure to
turn the switch off.

you (a) do not press the trip knob for 10
seconds or (b) open and close the driver’s
door, the fuel gauge needle will drop to the
“E”position and the dial and needle will
turn off.NOTE.You will see the“
”sign in the fuel
gauge.
This indicates that the fuel filler door
(lid) is located on the right side of the
vehicle.
.When you have refueled, the fuel
gauge indicates the amount in the fuel
tank after starting the engine. Also, it
may take some time until the fuel gauge
indication stabilizes.
.The gauge indicates only an approx-imate amount of fuel remaining in the
tank. Use this indication only as a
guide.
.If you refuel while the ignition switch
is in the“ON”position, the fuel gauge
may not indicate the correct amount of
the fuel in the fuel tank.
.If the refuel amount is less than
approximately 4.0 US gal (15 liters, 3.3
Imp gal), it may take some time until the
fuel gauge indication stabilizes.
&Temperature gauge1) Normal operating rangeThe temperature gauge shows engine
coolant temperature when the ignition
switch is in the“ON”position.
The coolant temperature will vary inaccordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range
and high revving operation when the
engine is not warmed up enough should
be avoided.
CAUTION
If the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.

&Door open warning lightThe warning light illuminates if any door or
the trunk lid is not fully closed. This
function is effective even if the ignition
switch is in the“LOCK”/“OFF”or“ACC”
position, or the key is removed from the
ignition switch.
Always make sure this light is not illumi-
nated before you start to drive.&All-Wheel Drive warn-
ing light (if equipped)This light flashes if the vehicle is driven
with tires of differing diameters fitted on the
wheels or with an excessively low air
pressure in any of the tires.
WARNING
Continued driving with the AWD
warning light flashing can lead to
powertrain damage. If the AWD
warning light flashes, promptly park
in a safe location and then check
whether all four tires are the same
diameter and whether any of the
tires has a puncture or has lost air
pressure.
NOTEIf the temporary spare tire is used, the
AWD warning light may flash. Use of the
temporary spare tire should therefore
be restricted to the minimum time
necessary. Replace the temporary
spare tire with a conventional tire as
soon as possible.&Power steering warning
light (except STI)While the engine is running, this warning
light illuminates when a malfunction has
been detected in the electric power steer-
ing system.
CAUTION
When the power steering warning
light is illuminated, there may be
more resistance when the steering
wheel is operated. Drive carefully to
the nearest SUBARU dealer and
have the vehicle inspected immedi-
ately.NOTEIf the steering wheel is operated in the
following ways, the power steering
control system may temporarily limitthe power assist in order to prevent the
system components, such as the con-
trol computer and drive motor, from
overheating.
.The steering wheel is operated fre-
quently and turned sharply while the
vehicle is maneuvered at extremely low
speeds, such as while frequently turn-
ing the steering wheel during parallel
parking.
.The steering wheel remains in the
fully turned position for a long period of
time.
At this time, there will be more resis-
tance when steering. However this is
not a malfunction. Normal steering
force will be restored after the steering
wheel is not operated for a while and
the power steering control system has
an opportunity to cool down. However,
if the power steering is operated in a
non-standard way which causes power
assist limitation to occur too frequently,
that may result in a malfunction of the
power steering control system.
&LED headlight warning
light (if equipped)This light illuminates if the LED headlights
malfunction. Have your vehicle inspected
at a SUBARU dealer as soon as possible.

CAUTION
Trapping small animals in the cool-
ing fan and belts of the engine may
result in a malfunction. Check that
no small animal enters the engine
compartment and under the vehicle
before starting the engine.NOTEEngine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.
Starting and stopping the en-
gine&General precautions when
starting/stopping engine
WARNING
.Never start the engine from out-
side the vehicle. It may result in
an accident.
.Do not start the engine near dry
foliage, paper, or other flammable
substances. The exhaust pipe
and exhaust emissions can cre-
ate a fire hazard at high tempera-
tures.
.Do not leave the engine running
in locations with poor ventilation,
such as a garage and indoors.
The exhaust gas may enter the
vehicle or indoors, and it may
result in carbon monoxide poi-
soning.
CAUTION
.Do not stop the engine while
driving. Otherwise, the catalyst
may overheat and burn.
.When starting the engine, be sureto sit in the driver’s seat (except
when using the remote engine
start system).
NOTE.Avoid rapid acceleration immedi-
ately after the engine has started. In
addition, always avoid rapid racing.
.Until the engine is warmed up suffi-
ciently, the engine speed is maintained
high. The engine speed will gradually
drop as the engine warms up.
.On rare occasions, it may be difficult
to start the engine depending on the
fuel used and the driving condition
(repeated short trips when the engine
is not warmed up sufficiently). In such
cases, it is recommended to switch to a
different brand of fuel.
.On rare occasions, transient knock-
ing may be heard from the engine when
the accelerator is operated rapidly such
as a rapid start-up and a rapid accel-
eration. This is not a malfunction.
.The engine starts more easily when
the headlights, air conditioner and rear
window defogger are turned off.
.It may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty is caused by the electronically

engine over-revving and this in turn
can result in engine damage.
In addition, sudden application of
engine brakes when the vehicle is
travelling on a slippery surface can
lead to wheel locking; as a conse-
quence, control of the vehicle may
be lost and the risk of an accident
increased.NOTENever exceed the posted speed limit.&Driving tips
NOTEIf the accelerator and brake pedals are
depressed at the same time, driving
torque may be restrained. This is not a
malfunction.
Do not drive with your foot resting on the
clutch pedal and do not use the clutch to
hold your vehicle at a standstill on an
upgrade. Either of those actions may
cause clutch damage.
Do not drive with your hand resting on the
shift lever. This may cause wear on the
transmission components.
When it is necessary to reduce vehicle
speed due to slow traffic, turning corners,
or driving up steep hills, downshift to alower gear before the engine starts to
labor.
On steep downgrades, downshift the
transmission to 5th, 4th, 3rd or 2nd gear
as necessary; this helps to maintain a safe
speed and to extend brake pad life.
In this way, the engine provides a braking
effect. Remember, if you“ride”(over use)
the brakes while descending a hill, they
may overheat and not work properly.
The engine may, on rare occasions, knock
when the vehicle rapidly accelerates or
rapidly pulls away from a standstill. This
phenomenon is not an indication of a
problem in your vehicle.
Driver’s Control Center Dif-
ferential (C.DIFF/DCCD) (STI)
WARNING
Always use the utmost care when
driving. Being overconfident be-
cause you are driving a vehicle with
a driver’s control center differential
could easily lead to a serious acci-
dent.

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

!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
