& Safety warnings
You will find a number of WARNINGs,
CAUTIONs and NOTEs in this manual.
These safety warnings alert you to poten-
tial hazards that could result in injury to
you or others.
Please read these safety warnings as well
as all other portions of this manual care-
fully in order to gain a better understand-
ing of how to use your SUBARU vehicle
safely.
WARNING
A WARNING indicates a situation in
which serious injury or death could
result if the warning is ignored.
CAUTION
A CAUTION indicates a situation in
which injury or damage to your
vehicle, or both, could result if the
caution is ignored.
NOTE
A NOTE gives information or sugges-
tions how to make better use of yourvehicle. & Safety symbol
You will find a circle with a slash through it
in this manual. This symbol means “Do
not ”, “Do not do this ”,or “Do not let this
happen ”, depending upon the context.

1-8Seat, seatbelt and SRS airbags
&Lumbar support (if equipped)
Pull the lever forward or backward.
Pulling the lever forward will increase the
amount of support for your lower back. Seat heater (if equipped)The seat heater is equipped in the front seats.
The seat heater operates when the igni-
tion switch is either in the
“Acc ”or “ON ”
position.
Each seat heater has four levels of
adjustment. To use the heater in the
right-hand seat, turn the “R ” adjustment
knob forward until the “
”mark reaches
the desired position. To activate the heater
in the left-hand seat, turn the “L ” adjust-
ment knob forward until the “
”mark
reaches the desired position. Each heater
warms the seat most quickly with the “
”
mark on the adjustment knob in the
furthest-forward position. An indicator light on the adjustment knob for each seat
heater comes on when that seat heater isactivated.
When the vehicle
’s interior is warmed
enough or before you leave the vehicle,
be sure to turn the switch off.
CAUTION
. There is a possibility that people
with delicate skin may suffer
slight burns even at low tempera-
tures if they use the seat heater
for a long period of time. When
using the heater, always be sure
to warn the persons concerned.
. 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.
NOTE
Use of the seat heater for a long period
of time while the engine is not running
can cause battery discharge.

Warning messages Details
Door open warning
When any of the doors, the rear gate (Station wagon) or the trunk lid
(Sedan) is not fully closed, it is indicated by the corresponding part of the
door light.
Always make sure this warning message is out before you start to drive.
The display shows the interruptive warning message for 3 seconds.
Parking brake warning
This warning message comes on with the parking brake applied while the
ignition switch is in the“ON ”position. It goes out when the parking brake is
fully released.
The display shows the interruptive warning message for 3 seconds and
then returns to its original display. The interruptive warning message will be
displayed again after 20 seconds.
Run mode change system warning
This warning message indicates a malfunction of the “SI-DRIVE mode ”
change. If this warning message is shown on the display, contact your
nearest SUBARU dealer and have the SI-DRIVE mode system inspected.
The display shows the interruptive warning message for 3 seconds.
Engine coolant temperature warning
When the engine coolant temperature reaches 248 8F (120 8C), this warning
message is indicated. If this warning message is displayed, refer to the “ Engine overheating
”section in chapter 9 for details the necessary measures.
The display shows the interruptive warning message for 3 seconds.

7-16Starting and operating
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 a
lower gear before the engine starts to
labor. .On steep downgrades, downshift the
transmission to 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 acceler-
ates or rapidly pulls away from a standstill.
This phenomenon does not indicate amalfunction. . A slight reduction in output torque may
occur in the models with a 2.5-liter turbo
engine before the engine warms up. Manual transmission
–6
speeds (2.5GT spec.B)
WARNING
Do not drive the vehicle with the
clutch disengaged (i.e., when the
clutch pedal is depressed) or with
the shift lever in the neutral position.
Engine braking has no effect in
either of these conditions and the
risk of an accident is consequentlyincreased.
The manual transmission is a fully syn-
chromeshed, 6-forward-speed and 1-re-
verse-speed transmission.
The shift pattern is shown on the shift lever knob. &
Selecting reverse gear
CAUTION
Shift into reverse ONLY when the
vehicle has completely stopped. It
may cause damage to the transmis-
sion to try shifting into reverse when
the vehicle is moving.
1) Slider
You must raise the slider and hold it in that
position before you can move the shift
lever to the “R ”position.
To change gears, fully depress the clutch
pedal, move the shift lever, and gradually

let up on the clutch pedal.
If it is difficult to shift into gear, put the
transmission in neutral, release the clutch
pedal momentarily, and then try again. &Shifting speeds
! Recommended shifting speeds
The best compromise between fuel econ-
omy and vehicle performance during
normal driving is ensured by shifting up
at the speeds listed in the following table.
Shift up mph (km/h)
1st to 2nd 15 (24)
2nd to 3rd 25 (40) 3rd to 4th 40 (64)
4th to 5th 45 (72)
5th to 6th 50 (80)
! Maximum allowable speeds
WARNING
When shifting down a gear, ensure
that the vehicle is not travelling at a
speed exceeding the Maximum Al-
lowable 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 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 accidentincreased.
The following tables show the maximum
speeds that are possible with each differ-
ent gear. The tachometer ’s needle will
enter the red area if these speeds areexceeded.
With the exception of cases where sudden
acceleration is required, the vehicle
should not be driven with the tachometer ’s
needle inside the red area. Failure to
observe this precaution can lead to
excessive engine wear and poor fuel
economy.
Gear mph (km/h)1st 33 (54)
2nd 51 (83)
3rd 69 (112)4th 90 (147)
5th 125 (204) 6th Top speed NOTE
Never exceed posted speed limits. &
Driving tips
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 a
lower 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 does not indicate a problem. Starting and operating

7-18Starting and operating
Automatic transmission –4-
speed
The 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“
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 selector lever
in the “P ” position. Avoid parking
for a long time with the selector
lever in any other position as
doing so could result in a dead
battery.
NOTE . When the engine coolant tempera-
ture is still low, your vehicle ’s auto-
matic transmission will up-shift at high-
er engine speeds than when the cool-
ant temperature is sufficiently high in
order 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 warmedup.. 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. &
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.

6. Remove the screwdriver from the hole.
Depress the brake pedal and start theengine.
Take your vehicle to the nearest SUBARU
dealer immediately to have the systemrepaired. 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 SI-DRIVE 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“
R ” position or vice versa until
the vehicle has completely
stopped. Such shifting may
cause damage to the transmis-sion.

7-32Starting and operating
& Sport Sharp (S#) mode
For maximum performance driving
For 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. & SI-DRIVE selector
When you rotate the SI-DRIVE selector to
the left, it changes to Sport (S) mode, and
when you rotate it to the right, it changes
to Sport Sharp (S#) mode, and when you
push it, it changes to Intelligent (I) mode. After performing this operation, the switch
returns to its original location.NOTE .
While the engine is cool, the S#
PREP indicator light of the temperature
gauge comes on. In this case, you
cannot change to Sport Sharp (S#)mode. . 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 comes on, 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. & SI-DRIVE Sport Sharp (S#) switch
While driving in the Sport (S) mode or
Intelligent (I) mode, when you push the
steering wheel switch, it changes to the
Sport Sharp (S#) mode.

Braking &Braking tips
WARNING
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.
! When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the vehicle
at a safe speed while lightly depressing
the brake pedal to heat up the brakes. ! Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To
help prevent this, shift into a lower gear to
get stronger engine braking. ! Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could cause a loss of control of the vehicle. Keep
driving straight ahead while gradually
reducing speed. Then slowly pull off the
road to a safe place.
& Brake system
! Two separate circuits
Your vehicle has a dual circuit brake
system. Each circuit works diagonally
across the vehicle. If one circuit of the
brake system should fail, the other half of
the system still works. If one circuit fails,
the brake pedal will go down much closer
to the floor than usual and you will need to
press it down much harder. And a much
longer distance will be needed to stop thevehicle. ! Brake booster
The brake booster uses engine manifold
vacuum to assist braking force. Do not
turn off the engine while driving because
that will turn off the brake booster, result-
ing in poor braking power.
The brakes will continue to work even
when the brake booster completely stops
functioning. If this happens, however, you
will have to push the pedal much harder
than normal and the braking distance willincrease. &
Disc brake pad wear warning indicators
The disc brake pad wear warning indica-
tors on the disc brakes give a warning
noise when the brake pads are worn.
If a squeaking or scraping noise is heard
from the disc brakes while braking, im-
mediately have your vehicle inspected by
the nearest SUBARU dealer.

!Driving on grades
. Before going down a steep hill, slow
down and shift into lower gear (if neces-
sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle ’s brakes. Do not
make sudden downshifts. . When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. . When driving uphill in hot weather, pay
attention to the water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT models) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air
conditioner and stop the vehicle at the
nearest safe place. Refer to the “Engine
overheating ”section in chapter 9, and
“ Warning and indicator lights ”section in
chapter 3. NOTE
With AT models, the temperature of
engine coolant is less likely to rise to
the OVERHEAT zone in the “D ” posi-
tion than in the manual mode position. . If your vehicle has an automatic trans- mission, avoid using the accelerator pedal
to stay stationary on an uphill slope
instead of using the parking brake or foot
brake. That may cause the transmission
fluid to overheat. !
Parking on a grade
Always block the wheels under both
vehicle and trailer when parking. Apply
the parking brake firmly. You should not
park on a hill or slope. But if parking on a
hill or slope cannot be avoided, you
should take the following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks
under both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then
apply the parking brake; slowly release
the regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P ” (automatic transmis-
sion) and shut off the engine. Driving tips
