. The transmission automatically se-
lects 1st gear when the vehicle stops
moving.
. 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. If the light comes on
while driving, it is unnecessary to stop
the vehicle, but avoid driving up steep
grades or in stop-and-go traffic.
& Maximum speeds
WARNING
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.
The following tables show the maximum
speeds that are possible with each differ-
ent gear.
When down shifting, it is important to
confirm that the current vehicle speed is
not in excess of the Maximum Allowable
Speed of the gear which is about to be
selected.

& Driving tips. 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.
. Always apply the foot or parking brake
when the vehicle is stopped in the “D”or
“R ”position.
. Always set the parking brake when
parking your vehicle. Do not hold the
vehicle with only the transmission.
. Do not keep the vehicle in a stationary
position on an uphill grade by using the
“D ”position. Use the brake instead.
. 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.
. A slight reduction in output torque may
occur in the models with a 3.0-liter or 2.5-

. 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. For 3.0-liter models, it also
changes to the Sport (S) mode when
the engine oil temperature increases.
Rear viscous limited slip dif-
ferential (LSD) (if equipped)
CAUTION
. Never start the engine while a tire
on one side is jacked up, as the
vehicle may move.
. If one rear tire is spinning in mud,
avoid continued spinning at high
speed as this could adversely
affect the LSD.
. If a different size rear tire is
temporarily used (as in an emer-
gency), it will adversely affect the
LSD. Always replace it with a
regularsizetireassoonas
possible.
The LSD provides optimum distribution of
power according to the difference in
revolutions 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.
Power steering
CAUTION
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.
The power steering system operates only
when the engine is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.NOTERight 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 steering pump which
is located at the right-front area of the
engine compartment. This noise is
normal. It does not indicate power
steering system trouble.

ABS (Anti-lock Brake Sys-
tem)
WARNING
Always use the utmost care in
driving –overconfidence because
youaredrivingwithanABS
equipped vehicle could easily lead
to a serious accident.
CAUTION
. The ABS system does not always
decrease stopping distance. You
should always maintain a safe
following distance from other
vehicles.
. When driving on badly surfaced
roads, gravel roads, icy road, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS
system than one without. When
driving under these conditions,
therefore, reduce your speed and
leave ample distance from other
vehicles.
. 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
operation of the ABS system.
The ABS system prevents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road sur-
faces. 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 not operate when the
vehicle speed is below approximately 6
mph (10 km/h).
& ABS system self-checkYou may feel a slight shock in the brake
pedal and hear the operating sound of
ABS from the engine compartment just
after the vehicle is started. This is caused
by an automatic functional test of the ABS
system being carried out and does not
indicate any abnormal condition.

two seconds.
This is an indication that the ABS system
is working properly.
CAUTION
If the warning light behaves as
follows, 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.
. The warning light does not come
on when the ignition switch is
turned to the “ON ”position.
. 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).
. 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.
NOTEIf the warning light behavior is as
described in the following, the ABS
system may be considered normal.
. The warning light comes on right
after the engine is started but goes out
immediately, remaining off.
. 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).
. 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 warning 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.
Electronic Brake Force Dis-
tribution (EBD) systemThe 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 braking 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
failsTurbo modelsNon-turbo modelsIf a malfunction occurs 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 driving.
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
applied harder than usual and the vehi-
cle
’s motion may therefore become some-
what 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 both
warning 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
inspected.
6. If the brake fluid level is below the
“MIN ”mark, DO NOT drive the vehicle.
Instead, have the vehicle towed to the
nearest SUBARU dealer for repair.
WARNING
. Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.
. If at all in doubt about whether
the brakes are operating prop-
erly, do not drive the vehicle.
Have your vehicle towed to the
nearest SUBARU dealer for re-
pair.

Vehicle Dynamics Control
system (if equipped)
WARNING
Always use the utmost care in
driving –overconfidence because
you are driving with a Vehicle Dy-
namics Control system equipped
vehicle could easily lead to a ser-
ious accident.
CAUTION
. Even if your vehicle is equipped
with Vehicle Dynamics Control,
winter tires or snow chains
should be used when driving on
snow-covered or icy roads; in
addition, vehicle speed should
be reduced considerably. Simply
having a Vehicle Dynamics Con-
trol system does not guarantee
that the vehicle will be able to
avoid accidents in any situation.
. Activation of the Vehicle Dy-
namics Control system is an
indication that the road being
travelled on has a slippery sur-
face; since having Vehicle Dy-
namics Control is no guarantee that full vehicle control will be
maintained at all times and under
all conditions, its activation
should be seen as a sign that
the speed of the vehicle should
be reduced considerably.
. Whenever suspension compo-
nents, steering components, or
an axle are removed from a
vehicle equipped with Vehicle
Dynamics Control, have an
authorized SUBARU dealer per-
form an inspection of that sys-
tem.
. The following precautions should
be observed in order to ensure
that the Vehicle Dynamics Con-
trol system is operating properly:
– All four wheels should be
fitted with tires of the same
size, type, and brand. Further-
more, the amount of wear
should be the same for all
four tires.
– Keep the tire pressure at the
proper level as shown on the
vehicle placard attached to
the driver ’s side door pillar.
In the event of wheelspin and/or skidding
on a slippery road surface and/or during cornering and/or an evasive maneuver,
the Vehicle Dynamics Control system
adjusts the engine
’s output and the
wheels ’respective braking forces to help
maintain traction and directional control.
. Traction Control Function
The traction control function is designed to
prevent spinning of the driving wheels on
slippery road surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown by
steady illumination of the Vehicle Dy-
namics Control operation indicator light.
. Skid Suppression Function
The skid suppression function is designed
to help maintain directional stability by
suppressing the wheels’ tendency to slide
sideways during steering operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light.
NOTE. Slight twitching of the brake pedal
may be felt when the Vehicle Dynamics
Control system operates; a small de-
gree of vehicle or steering wheel shak-
ing may also be noticed in this
situation. These are normal character-
istics of Vehicle Dynamics Control
operation and are no cause for alarm.

. When driving off immediately after
starting the engine, a short-lived opera-
tion noise may be noticed coming from
the engine compartment. This noise is
generated as a result of a check being
performed on the Vehicle Dynamics
Control system and is normal.
. Depending on the timing of activa-
tion of the brakes, certain situations
may occur just after driving off where
the brake pedal seems to exhibit a
jolting motion. This too is a conse-
quence of the Vehicle Dynamics Con-
trol operational check and is normal.
. In the circumstances listed in the
following, the vehicle may be more
unstable than it feels to the driver.
The Vehicle Dynamics Control System
may therefore operate. Such operation
does not indicate a system fault.
.on gravel-covered or rutted roads
. on unfinished roads
. when the vehicle is towing a
trailer
. when the vehicle is fitted with
snow tires or winter tires
. Activation of the Vehicle Dynamics
Control system will cause operation of
the steering wheel to feel slightly
different compared to that for normal
conditions.
. Even if the vehicle is equipped with a Vehicle Dynamics Control system, it
is important that winter tires be used
when driving on snow-covered or icy
roads. (All four wheels should be fitted
with tires of the same size and brand).
Furthermore, if snow chains are to be
used, they should be fitted on the front
wheels. When a vehicle is fitted with
snow chains, however, the effective-
ness of the Vehicle Dynamics Control
system is reduced and this should be
taken into account when driving the
vehicle in such a condition.
.
It is always important to reduce
speed when appro aching a corner,
even if the vehicle is equipped with
Vehicle Dynamics Control.
. All four wheels should be fitted with
tires of the same size, type, and brand;
furthermore, the amount of wear
should be the same for all four tires. If
these precautions are not observed
and non-matching tires are used, it is
quite possible that the Vehicle Dy-
namics Control system will be unable
to operate correctly as intended.
. Always turn off the engine before
replacing a tire as failure to do so may
render the Vehicle Dynamics Control
system unable to operate correctly.

above-mentioned situations.
NOTE.
When the switch has been pressed
to deactivate the Vehicle Dynamics
Control system, the Vehicle Dynamics
Control system automatically reacti-
vates itself the next time the ignition
switch is turned to the OFF position
and the engine is restarted.
. If the switch is held down for 10
seconds or longer, the indicator light
goes off, the Vehicle Dynamics Control
system is activated, and the system
ignores any further pressing of the

Tire pressure monitoring
system (TPMS) (if equipped)Turbo modelsNon-turbo models
The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 20 mph (32 km/h). Also,
this system may not react immediately to a
sudden drop in tire pressure (for example,
a blow-out caused by running over a
sharp object).
WARNING
If the low tire pressure warning light
comes on while driving, never brake
suddenly and keep driving straight
ahead while gradually reducing
speed. Then slowly pull off the road
to a safe place. Otherwise an acci-
dent involving serious vehicle da-
mage and serious personal injury
could occur.
Check the pressure for all four tires
and adjust the pressure to the COLD
tire pressure shown on the tire
placard on the door pillar on the
driver ’s side.
Even when the vehicle is driven a
very short distance, the tires get
warm and their pressures increase accordingly. Be sure to let the tires
cool thoroughly before adjusting
their pressures
to the standard
values shown on the tire placard.
(Refer to the “Tires and wheels ”
section in chapter 11.) The tire
pressure monitoring system does
not function when the vehicle is
stationary. After adjusting the tire
pressures, increase the vehicle
speed to at least 20 mph (32 km/h)
to start the TPMS re-checking of the
tire inflation pressures. If the tire
pressures are now above the severe
low pressure threshold, the low tire
pressure warning light should go off
a few minutes later.
If this light still comes on while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, replace it with a spare tire
as soon as possible. When a spare
tire is mounted or a wheel rim is
replaced without the original pres-
sure sensor/transmitter being trans-
ferred, the low tire pressure warning
light will flash. This indicates the
TPMS is unable to monitor all four
road wheels. Contact your SUBARU
dealer as soon as possible for tire

CAUTION
Never drive while the parking brake
is set because this will cause un-
necessary wear on the brake lin-
ings. Before starting to drive, always
make sure that the parking brake
has been fully released.
To set the parking brake, press the brake
pedal firmly and hold it down while fully
pulling up the parking brake lever.To release the parking brake, pull the lever
up slightly, press the release button, then
lower the lever while keeping the button
pressed.
When the parking brake is set while the
engine is running, the parking brake
warning light comes on. After starting the vehicle, be sure that the warning light has
gone out before the vehicle is driven.
Refer to the
“Warning and indicator lights ”
section (chapter 3).
When parking your vehicle, always set the
parking brake firmly and put the shift lever
in the “1” (1st) for an upgrade or “R”
(Reverse) for a downgrade for manual
transmission vehicles, or in the “P”(Park)
position for automatic transmission vehi-
cles. Always set the parking brake firmly
when parking your vehicle. Never rely on
the transmission alone to hold the vehicle.
When parking on a hill, always turn the
steering wheel. When the vehicle is
headed up the hill, the front wheels should
be turned away from the curb.
When facing downhill, the front wheels
should be turned into the curb.
