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.700346 700347
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.

– CONTINUED –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
T When 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.

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 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 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. 700349

– CONTINUED –Vehicle Dynamics Control
system (if equipped)y 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.
y If at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest
SUBARU dealer for repair. Always use the utmost care in driv-
ing – overconfidence because you
are driving with a Vehicle Dynamics
Control system equipped vehicle
could easily lead to a serious acci-
dent.
y 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 ad-
dition, vehicle speed should be re-
duced considerably. Simply hav-
ing a Vehicle Dynamics Control
system does not guarantee that
the vehicle will be able to avoid
accidents in any situation. y Activation of the Vehicle Dynam-
ics Control system is an indica-
tion that the ro ad being travelled
on has a slippery surface; since
having Vehicle Dynamics 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.
y Whenever suspension compo-
nents, steering components, or an
axle are removed from a vehicle
equipped with Vehicle Dynamics
Control, have an authorized
SUBARU dealer perform an in-
spection of that system.
y The following precautions should
be observed in order to ensure
that the Vehicle Dynamics Control
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 all four tires.

7-30 Starting and operating
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 ad-
justs 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 surfaces, thereby helping to
maintain traction and directional control.
Activation of this function is shown by
steady illumination of the Vehicle Dynam-
ics Control 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 operations. Acti-
vation of this function is shown by flashing
of the Vehicle Dynamics Control operation
indicator light.
NOTE
y Slight twitching of the brake pedal may be felt when the Vehicle Dynamics
Control system operates; a small de-
gree of vehicle or st eering wheel shak-
ing may also be noticed in this situa-
tion. These are normal characteristics
of Vehicle Dynamics Control operation
and are no cause for alarm.
y When driving off immediately after
starting the engine, a short-lived oper-
ation 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 nor-
mal.
y 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 jolt-
ing motion. This too is a consequence
of the Vehicle Dynamics Control opera-
tional check and is normal.
y In the circumstances listed in the fol-
lowing, the vehicle may be more unsta-
ble than it feels to the driver. The Vehi-
cle Dynamics Control System may
therefore operate. Such operation does
not indicate a system fault.
y on 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 Vehicle Dynamics
Control system will cause operation of
the steering wheel to feel slightly dif-
ferent compared to that for normal con-
ditions.
y 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 ve-
hicle in such a condition.
y It is always important to reduce
speed when approaching a corner,
even if the vehicle is equipped with Ve-
hicle Dynamics Control.
y All four wheels shou ld 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 Dynam-
ics Control system will be unable to op-– Keep the tire pressure at the
proper level as shown on the
vehicle placard attached to the
driver’s side door pillar.

7-32 Starting and operating
tems.
Because the Vehicle Dynamics Control
system controls each brake through the
ABS, whenever the ABS stops operating
due to a malfunction in that electrical sys-
tem, the Vehicle Dynamics Control will
also become unable to control all four
brakes. Thus Vehicle Dynamics Control
system operation halt s and the warning
light turns on. Although both the Vehicle
Dynamics Control system and the ABS
will be inoperable in this situation, it will
still be possible to stop the vehicle using
normal braking. The Vehicle Dynamics
Control system and the ABS do not ad-
versely affect operation of the vehicle in
any way when they are inoperable; how-
ever should such a situation occur, drive
with care and have an authorized
SUBARU dealer carry out an inspection of
those systems at the first available oppor-
tunity.
NOTE When the warning light turns on and
off in the following way, it indicates
that the Vehicle Dynamics Control sys-
tem is operating normally.
y Although turning on after the engine
has been started, the warning light
quickly turns off and stays off.
y The warning light turns on when the vehicle is being driven; it then turns off
and stays off.
V Vehicle Dynamics Control OFF indi-
cator light
This light comes on to indicate that the Ve-
hicle Dynamics Control system is in non-
operation mode. This does not constitute
failure of the Vehicle Dynamics Control
system.
NOTE y The 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 tem-
perature.
y When an engine problem occurs and
the malfunction indicator lamp turns
on, the indicator light will also come
on.
The following two situations could indicate
malfunction of the Vehicle Dynamics Con-
trol system; if either should occur, have an
authorized SUBARU dealer carry out an
inspection of that syst em at the first avail-
able opportunity.
y The indicator light does not turn on
when the ignition switch is turned to the ON position.
y The indicator light fail s to turn off after
the engine is started, even when several
minutes have passed to allow the engine
to heat up sufficiently.
„ Vehicle Dynamics Control
OFF switch
Pressing the switch to deactivate the Ve-
hicle Dynamics Contro l system can facili-
tate the following operations:
y a standing start on a steeply sloping
road with a snowy, grav el-covered, or oth-
erwise slippery surface
y extrication of the vehicle when its
wheels are stuck in mud or deep snow
When the switch is pressed during engine
operation, the indicator light illuminates. 700114

Starting and operating
7-33
– CONTINUED –The Vehicle Dynamics Control system will
be deactivated and the vehicle will behave
like a model not equipped with the Vehicle
Dynamics Control system. When the
switch is pressed again to reactivate the
Vehicle Dynamics Control system, the in-
dicator light goes off.
With the Vehicle Dynamics Control sys-
tem deactivated, traction and stability en-
hancement offered by Vehicle Dynamics
Control system is unavailable. Therefore
you should not deactivate the Vehicle Dy-
namics Control syst em except under
above-mentioned situations.
NOTE y 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.
y If the switch is held down for 10 sec-
onds or longer, the indicator light goes
off, the Vehicle Dynamics Control sys-
tem is activated, and the system ig-
nores any further pressing of the
switch. To make the switch usable
again, turn the igni tion switch to the
OFF position and restart the engine.
y When the switch is pressed to deac- tivate the Vehicle Dynamics Control
system, the vehicle’s running perfor-
mance is comparable with that of a ve-
hicle that does not have a Vehicle Dy-
namics Control system. Do not deacti-
vate the Vehicle Dynamics Control sys-
tem except when absolutely neces-
sary.
Tire pressure monitoring
system (TPMS) (if equipped)
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 mo nitoring 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 exam-
ple, a blow-out caused by running over a
sharp object). 700352

7-34 Starting and operating
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 dam-
age 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 plac-
ard 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 val-
ues shown on the tire placard. (Re-
fer to the “Tires and wheels” section
in chapter 11.) The tire pressure
monitoring system does not func-
tion 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 infla-
tion pressures. If the tire pressures
are now above the severe low pres-
sure threshold, the low tire pressure
warning light should go off a few
minutes later. If this light still comes on while driv-
ing after adjusting the tire pressure,
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 pressure sen-
sor/transmitter being transferred,
the low tire pressure warning light
will flash. This indicates the TPMS is
unable to monitor all four road
wheels. Contact your SUBARU deal-
er as soon as possible for tire and
sensor replacement and/or system
resetting.
Do not inject any tire liquid or aero-
sol tire sealant into the tires, as this
may cause a malfunction of the tire
pressure sensors. If the light flash-
es, promptly contact a SUBARU
dealer to have the system inspect-
ed.

7-36 Starting and operating
cle, be sure that the warning light has
gone out before the vehicle is driven. Re-
fer 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” (Re-
verse) for a downgrade for manual trans-
mission vehicles, or in the “P” (Park) posi-
tion for automatic transmission vehicles.
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 head-
ed 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. Cruise control Cruise control enables you to maintain a
constant vehicle speed without holding
your foot on the accelerator pedal and it is
operative when the vehicle speed is 25
mph (40 km/h) or more. Make sure the
main switch is turned “OFF” when the
cruise control is not in use to avoid unin-
tentionally setting the cruise control.
NOTE If you move the cruise control lever or
press the main switch button while
turning the ignition switch “ON”, the
cruise control function is deactivated
and the “CRUISE” indicator light flash-
es. To reactivate the cruise control
function, turn the ignition switch back
to the “ACC” or “LOCK” position, and
then turn it again to the “ON” position.
700117 700118
Do not use the cruise control under
any of the following conditions. This
may cause loss of vehicle control:
y driving up or down a steep grade
y driving on slippery or winding
roads
y driving in heavy traffic
