matic transmission from damage. yAutomatic gearshifts do not take place in the
SPORTSHIFT mode. Perform gearshifts in accor-
dance with road conditions so that the tachometer
needle does not enter the red zone. If the engine
speed reaches a predetermined level, a fuel-cut
function will operate. Shift up if this happens. 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 transmission will not respond. y You can perform a skip-shift (for example, from
4th to 2nd or from 2nd to 4th) by operating the se-
lector lever twice in rapid succession.y The transmission automatically selects 1st gear
when the vehicle stops moving. It will not permit a
standing start in 2nd gear. T Maximum speeds
When down shifting a gear, ensure that the ve-
hicle 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 brak-
ing caused by downshifting when the vehicle is
travelling 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
increased.
The following tables show the maximum speeds that
are possible with each different 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 se- lected.
NOTE
In order to prevent over-revving during decelera-
tion of the vehicle, the transmission will remain in
the current gear if the speed of the vehicle is in ex-
cess of the Maximum Allowable Speed for the gear
to which the selector lever has been moved.

T Driving tips
y Always apply the foot or parking brake when the ve-
hicle is stopped in the “D”, “3”, “2”, “1”, or “R” position. y Always set the parking brake when parking your ve-
hicle. Do not hold the vehicle with only the transmis- sion. y Do not keep the vehicle in a stationary position on
an uphill grade by using the “D”, “3”, “2” or “1” position.
Use the brake instead. y 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 fault. „
Shift lock release
If the selector lever does not move from the “P” posi-
tion with the brake pedal depressed and the ignition
switch in the “ON” position, perform the followingsteps:
To override the shift lock:
1. Set the parking brake and stop the engine.
2. Take out the screwdriver from the tool bag.
3. Remove the cover by prying on the edge with the
regular screwdriver.

4. Insert the screwdriver into the hole.
5. Push down on the screwdriver, push down the but-
ton and move the selector lever from the “P” to the “N”position.
6. Remove the screwdriver from the hole. Depress
the brake pedal and start the engine.
Take your vehicle to the nearest SUBARU dealer im-
mediately to have the system repaired. Rear viscous limited slip differential
(LSD) (if equipped)
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 con-
tinued spinning at high speed as this could ad-
versely affect the LSD. y If a different size rear tire is temporarily used
(as in an emergency), it will adversely affect the
LSD. Always replace it with a regular size tire as
soon as possible.
The LSD provides optimum distribution of power ac-
cording to the difference in revolutions between the
right and left rear wheels that may be caused by cer-
tain driving conditions, thereby improving driving sta-
bility on snow-covered, muddy or other slippery roads.

Starting and operating
Power steering
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.
NOTE
Right after the engine has been started and before
it has warmed up, you may hear a noise coming
from areas adjacent to the power steering pump
which is located at the right-front area of the en-
gine compartment. This noise is normal. It does
not indicate power steering system trouble.
Braking „ Braking tips
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.
T When the brakes get wet
When driving in rain or after washing the vehicle, the
brakes may get wet. As a result, brake stopping dis-
tance will be longer. To dry the brakes, drive the vehi-
cle 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 descending a grade, if only the
foot brake is used, the brakes may start working im-
properly because of brake fluid overheating, caused
by overheated brake pads. To help prevent this, shift
into a lower gear to get stronger engine braking.

TBraking 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
T Two separate circuits
Your vehicle has two separate circuit brake systems.
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 the vehi- cle. 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, re-
sulting 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. „
Disc brake pad wear warning indica- tors
The disc brake pad wear warning indicators 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, immediately have your vehicle
checked by your SUBARU dealer.

ABS (Anti-lock Brake System)
Always use the utmost care in driving – over-
confidence because you are driving with an
ABS equipped vehicle could easily lead to a se-
rious accident.
y
The ABS system does not always decrease
stopping distance. You should always maintain
a safe following distance from other vehicles. 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, re-
duce your speed and leave ample distance from
other vehicles. y When you feel the ABS system operating,
you should maintain constant brake pedal pres-
sure. 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 slip-
pery road surfaces. 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-check
You may feel a slight shock in the brake pedal and hear the operating sound of ABS from the engine com-
partment just after the vehicle is started. This is
caused by an automatic functional test of the ABS sys-
tem being carried out and does not indicate any abnor-
mal condition.

„ABS warning light
The ABS warning light comes on when the ignition
switch is turned to the “ON” position and goes out after
about two seconds.
This is an indication that the ABS system is working
properly.
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 continues to operate normally. 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 during driving.
If these occur, have the ABS system repaired at
the first available opportunity by your SUBARU
dealer.
NOTE
If the warning light behavior is as described be-
low, the ABS system may be considered normal. y The warning light comes on right after the en-
gine is started but goes out immediately, remain-
ing off. y The warning light remains on after the engine
has been started, but it goes out when the vehicle
speed reaches about 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 warning
light may come on. This is due to the low battery volt-UB4010LA

yWhenever suspension components, steering
components, or an axle are removed from a ve-
hicle equipped with VDC, have an authorized
SUBARU dealer perform an inspection of that
system.y The following precautions should be ob-
served in order to ensure that the VDC system
is operating properly:
– 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 allfour tires.
– Keep the tire pressure at the proper level as
shown on the placard attached to the vehi-
cle’s door pillar.
– Use only the special temporary spare tire to
replace a flat tire. With a temporary spare tire,
the effectiveness of the VDC system is re-
duced and this should be taken into account
when driving with vehicle.
In the event of wheelspin and/or skidding on a slippery
road surface and/or during cornering and/or an eva-
sive maneuver, the VDC system adjusts the engine’s
output and the wheels’ respective braking forces to
help maintain traction and directional control. y
Traction Control Function
The traction control function is designed to prevent
spinning of the driving wheels on slippery road surfac-
es, thereby helping to maintain traction and directional
control. Activation of this function is shown by steady
illumination of the VDC operation indicator light. y Skid Suppression Function
The skid suppression function is designed to help
maintain directional stability by suppressing the
wheels’ tendency to slide sideways during steering op-
erations. Activation of this function is shown by flash-
ing of the VDC operation indicator light.
NOTE y Slight twitching of the brake pedal may be felt
when the VDC-system operates; a small degree of
vehicle or steering wheel shaking may also be no-
ticed in this situation. These are normal character-
istics of VDC operation and are no cause for
alarm. y When driving off immediately after starting the
engine, a short-lived operation noise may be no-
ticed coming from the engine compartment. This
noise is generated as a result of a check being per-
formed on the VDC system and is normal.y Depending on the timing of activation of the
brakes, certain situations may occur just after

Starting and operating
driving off where the brake pedal seems to exhibit
a jolting motion. This too is a consequence of the
VDC operational check and is normal. y
In the circumstances listed below, the vehicle
may be more unstable than it feels to the driver.
The Vehicle Dynamics Control System may there-
fore operate. Such operation does not indicate a
system fault.
yon gravel-covered or rutted roads
y on unfinished roads
y when the vehicle is towing a trailer
y when the vehicle is fitted with snow tires or
winter tires
y Activation of the VDC system will cause opera-
tion of the steering wheel to feel slightly different
compared to that for normal conditions. y Even if the vehicle is equipped with a VDC sys-
tem, 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). y It is always important to reduce speed when ap-
proaching a corner, even if the vehicle is equipped with VDC. y 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 VDC system will be unable to operate cor-
rectly as intended. y
Always turn off the engine before replacing a
tire as failure to do so may render the VDC system
unable to operate correctly. „ VDC system monitor

yThis light turns on to indicate that the VDC system
is in non-operation mode. This does not constitute fail- ure of the VDC system.
NOTE y The VDC OFF indicator light may stay on for a
while after the engine has been started, especially
in cold weather. This occurs because the engine
has not yet warmed up and is completely normal.
The light will turn off when the engine has reached
a suitable operating temperature. y When an engine problem occurs and the CHECK
ENGINE warning light turns on, the VDC OFF indi-
cator light will also turn on.
The following two situations could indicate malfunction
of the VDC system; if either should occur, have an au-
thorized SUBARU dealer carry out an inspection of
that system at the first available opportunity. y The VDC OFF indicator light does not turn on when
the ignition key is turned to the ON position. y The VDC OFF indicator light fails to turn off after the
engine is started, even when several minutes have
passed to allow the engine to heat up sufficiently. T VDC operation indicator light
The VDC operation indicator light turns on when the
ignition key is turned to the ON position; it turns off ap- proximately two seconds later. This indicator light
flashes during activation of the skid suppression func-
tion and is illuminated steadily during activation of the
traction control function.
The following two situations could indicate a malfunc-
tion of the VDC system; if either should occur, have an
authorized SUBARU dealer carry out an inspection of
that system at the first available opportunity.y
The VDC operation indicator light does not turn on
when the ignition key is turned to the ON position.y The VDC operation indicator light does not turn off
approximately two seconds after the ignition key has
been turned to the ON position. T V D C w a r n i n g l i g h t
The VDC warning light turns on when the ignition key
is turned to the ON position and off when the engine is
started. This lighting pattern indicates that the VDC
system is operating normally.
The following situations could indicate a malfunction of
the VDC system; if any should occur, have an autho-
rized SUBARU dealer carry out an inspection of the
