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.

7-22 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.yWhen 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 goesoff. „
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.

Never exceed posted speed limits.
„ Driving tips
y On a road surface where there is a risk
of wheelspin (for example, a snow- or
gravel-covered road), you can pull away
from a standstill safely and easily by first
selecting the 2nd gear of the manual
mode.y Always apply the foot or parking brake
when the vehicle is stopped in the “D” or
“R” position.y Always set the parking brake when
parking your vehicle. Do not hold the vehi-
cle with only the transmission.y Do not keep the vehicle in a stationary
position on an uphill grade by using the
“D” position. Use the brake instead.y 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 fault. y
A slight reduction in output torque may
occur in the models with a 3.0-liter or 2.5-
liter turbo engine before the engine warms
up. „ SPORT mode
SPORT mode is used when power is
needed for rapid acceleration or for uphill
driving. To select this mode, move the se-
lector lever from the “D” position to the
manual gate. When selected, the SPORT mode indica-
tor light on the instrument panel will turn
on.
To deselect SPORT
mode, move the se-
lector lever to the “D ” position or select
manual mode. To subsequently reselect
SPORT mode, move the selector lever to
the “D” position and from there to the man-
ual gate.
In this mode, the transmission shifts up at
higher vehicle speeds and shifts down
more responsively t han in normal mode.
„ Shift lock release
If the selector lever does not move from
the “P” position with the brake pedal de-
pressed and the ignition switch in the “ON”
position, perform the following steps:

7-24 Starting and operating
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 screwdriver 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. Rear viscous limited slip dif-
ferential (LSD) (if equipped)
The LSD provides optimum distribution of
power according to the difference in revo-
lutions between the right and left rear
wheels that may be caused by certain
driving conditions, thereby improving driv-
ing stability on snow-covered, muddy or
other slippery roads.

y
Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
y If one rear tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely af-
fect the LSD.
y If a different size rear tire is tem-
porarily used (as in an emergen-
cy), it will adversely affect the
LSD. Always replace it with a reg-
ular size tire as soon as possible.

Power steering
The power steering system operates only
when the engine is running.
If you lose power stee ring assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.
NOTE
Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power st eering pump which
is located at the right-front area of the
engine compartment. This noise is nor-
mal. It does not indicate power steering
system trouble.
Braking „ Braking tips
TWhen the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a re-
sult, brake stopping distance will be long-
er. To dry the brakes, drive the vehicle at
a safe speed while lightly depressing the
brake pedal to heat up the brakes. T 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. T 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 driv-
ing straight ahead while gradually reduc-
ing speed. Then slowly pull off the road to
a safe place. „
Brake system
T Two separate circuits
Your vehicle has a dual circuit brake sys-
tem. Each circuit works diagonally across
the vehicle. If one circuit of the brake sys-
tem should fail, the other half of the sys-
tem 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 the vehicle. T 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 will
increase.
Do not hold the steering wheel at the
fully locked position
left or right for
more than five seconds. This may
damage the power steering pump.
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.

7-26 Starting and operating
„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, imme-
diately have your vehicle inspected by the
nearest SUBARU dealer. ABS (Anti-lock Brake Sys-
tem)
The ABS system prev
ents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road surfac-
es. This helps prevent the loss of steering
control and directional stability caused by
wheel lock-up. When the ABS system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
when the ABS operates. The ABS system will no t operate when the
vehicle speed is below approximately 6
mph (10 km/h). „ ABS system self-check
You may feel a slight shock in the brake
pedal and hear the operating sound of
ABS from the engine compartment just af-
ter the vehicle is started. This is caused by
an automatic functional test of the ABS
system being carried out and does not in-
dicate any abnormal condition.
700040
Always use the utmost care in driv-
ing – overconfidence because you
are driving with an ABS equipped
vehicle could easily lead to a seri-
ous accident. y The ABS system does not always
decrease stopping distance. You
should always maintain a safe fol-
lowing distance from other vehi-
cles.
y When driving on badly surfaced
roads, gravel roads, icy road, or
over deep newly fallen snow,
stopping distances may be longer
for a vehicle with the ABS system
than one without. When driving
under these conditions, therefore,
reduce your speed and leave am-
ple distance from other vehicles.
y When you feel the ABS system
operating, you should maintain
constant brake pedal pressure.
Do not pump the brake pedal
since doing so may defeat the op-
eration of the ABS system.

Starting and operating 7-27
„ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON” posi-
tion and goes out after approximately two
seconds.
This is an indication that the ABS system
is working properly.
NOTE
If the warning light behavior is as de-
scribed in the following, the ABS sys-
tem may be considered normal. y The warning light comes on right af-
ter the engine is started but goes out
immediately, remaining off. y The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h). y The warning light comes on during
driving, but it goes out immediately
and remains off.
When driving with an insufficient battery voltage such as when the engine is jump started, the ABS warn
ing light may come
on. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out.
If the warning light behaves as fol-
lows, the ABS system may not be
working properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally.
700348
y The warning light does not come
on when the ignition switch is
turned to the “ON” position.
y The warning light comes on when
the ignition switch is turned to the
“ON” position, but it does not go
out even when the vehicle speed
exceeds approximately 8 mph (12
km/h).
y The warning light comes on dur-
ing driving.
If these occur, have the ABS system
repaired at the first available oppor-
tunity by your SUBARU dealer.

7-28 Starting and operating
Electronic Br ake Force Dis-
tribution (EBD) system
The EBD system maximizes the effective-
ness of the brakes by allowing the rear
brakes to supply a greater proportion of
the braking force. It functions by adjusting
the distribution of brak ing force to the rear
wheels in accordance with the vehicle’s
loading condition and speed.
The EBD system is an integral part of the
ABS system and uses some of the ABS
system’s components to perform its func-
tion of optimizing the distribution of brak-
ing force. If any of the ABS components
used by the EBD function fails, the EBD
system also stops working.
When the EBD system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
and does not indicate a malfunction. „
Steps to take if EBD system fails
If a malfunction occu rs in the EBD system,
the system stops working and the brake system warning light and ABS warning
light come on simultaneously. The EBD system may be faulty if the brake
system warning light and ABS warning
light illuminate simultaneously during driv-
ing.
Even if the EBD system fails, the conven-
tional braking system will still function.
However, the rear wheels will be more
prone to locking when the brakes are ap-
plied harder than usual and the vehicle’s
motion may therefore become somewhat
harder to control.
If the brake system warning light and ABS warning light illuminate simultaneously,
take the following steps:
1. Stop the vehicle in the nearest safe, flat
place.
2. Shut down the engine, then restart it.
3. Release the parking brake. If bothwarning lights go out, the EBD system
may be faulty.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
4. If both warning lights come on again
and stay illuminated after the engine has
been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level.
5. If the brake fluid level is not below the
“MIN” mark, the EBD system may be
faulty. Drive carefully to the nearest
SUBARU dealer and have the system in-spected.
6. If the brake fluid level is below the
“MIN” mark, DO NOT drive the vehicle. In-
stead, have the vehicle towed to the near-
est SUBARU dealer for repair.
