&Precautions against vehicle modification
Always consult your SUBARU dealer if
you want to install any accessory parts to
your vehicle.
CAUTION
Do not perform any of the following
modifications. Such modifications
can interfere with proper operation
of the seatbelt pretensioners. . Attachment of any equipment
(bush bar, winches, snow plow,
skid plate, etc.) other than genu-
ine SUBARU accessory parts to
the front end.
. Modification of the suspension
system or front end structure.
. Installation of a tire of different
size and construction from the
tires specified on the vehicle
placard attached to the door
pillar or specified for individual
vehicle models in this Owner ’s
Manual. Child restraint systems
Infants and small children should always
be placed in an infant or child restraint
system in the rear seat while riding in the
vehicle. You should use an infant or child
restraint system that meets Federal Motor
Vehicle Safety Standards or Canada
Motor Vehicle Safety Standards, is com-
patible with your vehicle and is appro-
priate for the child
’s age and size. All child
restraint systems are designed to be
secured in vehicle seats by lap belts or
the lap belt portion of a lap/shoulder belt
(except those covered under the section in
this manual, entitled “Installation of child
restraint systems by use of lower and
tether anchorages (LATCH) ”).
Children could be endangered in an accident if their child restraints are not
properly secured in the vehicle. When
installing the child restraint system, care-
fully follow the manufacturer
’s instructions.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front
seating positions.
All U.S. states and Canadian provinces
require that infants and small children be
restrained in an approved child restraint
system at all times while the vehicle ismoving.

&Precautions against vehicle modification
WARNING
. To avoid accidental activation of
the system or rendering the sys-
tem inoperative, which may re-
sult in serious injury, no modifi-
cations should be made to any
components or wiring of the SRS
airbag system.
This includes following modifica- tions: . Installation of custom steering
wheels
. Attachment of additional trim
materials to the dashboard
. Installation of custom seats
. Replacement of seat fabric or
leather
. Installation of additional fabric
or leather on the front seat
. Attachment of a hands-free
microphone or any other ac-
cessory to a front pillar, a
center pillar, a rear pillar, the
windshield, a side window, an
assist grip, or any other cabin
surface that would be near a deploying SRS curtain airbag.
. Installation of additional elec-
trical/electronic equipment
such as a mobile two-way
radioonorneartheSRS
airbag system components
and/or wiring is not advisable.
This could interfere with prop-
er operation of the SRS airbagsystem.
CAUTION
Do not perform any of the following
modifications. Such modifications
can interfere with proper operation
of the SRS airbag system. . Attachment of any equipment
(bush bar, winches, snow plow,
skid plate, etc.) other than genu-
ine SUBARU accessory parts.
. Modification of the suspension
system or front end structure.
. Installation of a tire of different
size and construction from the
tires specified on the vehicle
placard attached to the driver ’s
door pillar or specified for indivi-
dual vehicle models in this Own-er ’s Manual. .
Attachment of any equipment
(side steps or side sill protectors,
etc.) other than genuine SUBARU
accessory parts to the side body.
Always consult your SUBARU dealer if
you want to install any accessory parts on
your vehicle.

properly. If there is no problem and all tires
are properly inflated, the light will go out.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on
the vehicle placard or tire inflation pres-
sure label, you should determine the
proper inflation pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver ’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of re-
placement or alternate tires or wheels on
the vehicle that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.
Should the warning light illuminate stea-
dily after blinking for approximately one
minute, have the system inspected by
your nearest SUBARU dealer as soon aspossible.WARNING
If this light does not come on briefly
after the ignition switch is turned ON
or the light illuminates steadily after
blinking for approximately one min-
ute, you should have your Tire
Pressure Monitoring System
checked at a SUBARU dealer as
soon as possible.
If this light comes on while driving,
never brake suddenly and keep
driving straight ahead while gradu-
ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving
serious vehicle damage and serious
personal injury could occur.
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 pressure sensor/transmitter
being transferred, the Low tire pres-
sure warning light will illuminates
steadily after blinking for approxi-
mately one minute. This indicates Instruments and controls

the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.
CAUTION
The tire pressure monitoring system
is NOT a substitute for manually
checking tire pressure. The tire
pressure should be checked peri-
odically (at least monthly) using a
tire gauge. After any change to tire
pressure(s), the tire pressure mon-
itoring system will not re-check tire
inflation pressures until the vehicle
is first driven more than 20 mph (32
km/h). After adjusting the tire pres-
sures, 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
pressure threshold, the low tire
pressure warning light should go
off a few minutes later. Therefore, be
sure to install the specified size for the front and rear tires.
& ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON ”
position and goes out after approximately
2 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
work 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 tothe “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 any of these conditions occur,
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer.
The ABS warning light comes on together
with the brake system warning light if the
EBD system becomes faulty. For further
details of the EBD system fault warning,
refer to “Brake system warning light ”.
NOTE
If 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.

NOTE
While driving in Sport Sharp (S#) mode,
when you push the switch, it changes
to the former mode before Sport Sharp
(S#) mode.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
regularsizetireassoonaspossible.
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 5 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 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. Starting and operating

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.
– Use only the specified tem-
porary spare tire to replace a
flat tire. With a temporary spare tire, the effectiveness of
the Vehicle Dynamics Control
system is reduced and this
should be taken into account
when driving the vehicle in
such a condition.
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 situa-
tion. These are normal characteristics
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, the brake pedal may
seem to jolt when you drive off after
starting the engine. This 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 normalconditions. . 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.

Driving in foreign countries
When planning to use your vehicle in
another country: .Confirm the availability of the correct
fuel. (Refer to the “Fuel requirements ”
section in chapter 7.). Comply with all regulations and re-
quirements of each country. Driving tips for AWD vehicles
WARNING
. Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden brak-
ing or under other similar condi-tions.
. Always use the utmost care in
driving –overconfidence be-
cause you are driving an All-
Wheel Drive vehicle could easily
lead to a serious accident.
All-Wheel Drive distributes the engine power to all four wheels. AWD vehicles
provide better traction when driving on
slippery, wet or snow-covered roads and
when moving out of mud, dirt and sand.
By shifting power between the front and
rear wheels, SUBARU AWD can also
provide added traction during accelera-
tion, and added engine braking force
during deceleration.
Therefore, your SUBARU AWD vehicle
may handle differently than an ordinary
two wheel drive vehicle and it contains
some features unique to AWD. For safety
purposes as well as to avoid damaging
the AWD system, you should keep the
following tips in mind: .
An AWD vehicle is better able to climb
steeper roads under snowy or slippery
conditions than a two wheel drive vehicle.
There is little difference in handling,
however, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an
ample distance from other vehicles. . When replacing a tire, make sure you
use only the same size, circumference,
construction, brand, and load range as the
original tires listed on the tire placard.
Using other sizes, circumferences or
construction may result in severe mechan-
ical damage to the drive train of your Driving tips

tion, and clearance between the body
and tires. It also may be dangerous and
lead to loss of vehicle control. .If you use a temporary spare tire to
replace a flat tire, be sure to use the
original temporary spare tire stored in the
vehicle. Using other sizes may result in
severe mechanical damage to the drive
train of your vehicle. . Always check the cold tire pressure
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, which is located under the
door latch on the driver ’s side.
. Tire chains should always be placed on
the front wheels only. . There are some precautions that you
must observe when towing your vehicle.
For detail information, refer to the “Towing ”
section in chapter 9. Off road driving
WARNING
. Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden brak-
ing or under other similar condi-tions.

& All AWD models except OUTBACK
Your AWD vehicle is neither a conven-
tional off-road vehicle nor an all terrain
vehicle. It is a passenger car designed
primarily for on-road use. The AWD
feature gives it some limited off-road
capabilities in situations in which driving
surfaces a relatively level, obstruction-free
and otherwise similar to on-road driving
conditions. Operating it under other than
those conditions could subject the vehicle
to excessive stress which might result in damage not eligible for repair under
warranty. If you do take your SUBARU
off road, you should review the common
sense precautions in the next section
(applicable to the OUTBACK) for general
guidance. But please keep in mind that
your vehicle
’s off-road capabilities are
more limited than those of the OUTBACK.
Never attempt to drive through pools and
puddles, or roads flooded with water.
Water entering the engine air intake or
the exhaust pipe or water splashing onto
electrical parts may damage your vehicle
and may cause it to stall. & OUTBACK
Because of the AWD feature and higher
ground clearance, your SUBARU can be
driven on ordinary roads or off-road. But
please keep in mind that an AWD
SUBARU is a passenger car and is
neither a conventional off-road vehicle
nor an all-terrain vehicle. If you do take
your SUBARU off-road, certain common
sense precautions such as the following
should be taken: . Make certain that you and all of your
passengers are wearing seatbelts. . Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio.

&Snow tires
! All models except OUTBACK or
2.5GT spec.B
WARNING
. When replacing original tires with
winter (snow) tires, make sure
you use only the same size,
construction and load range as
the original tires listed on the tire
placard. Using other sizes and
construction may affect speed-
ometer/odometer calibration and
clearance between the body and
tires. It also may be dangerous
and lead to loss of vehicle con-trol.
. You must install four winter tires
that are of the same size, circum-
ferences, construction, brand,
and load range. Mixing other
sizes, circumferences or con-
structions may result in severe
mechanical damage to the drive
train of your vehicle and may
affect ride, handling, braking and
speedometer/odom eter calibra-
tion. It also may be dangerous
and lead to loss of vehicle con-trol. .
Do not use a combination of
radial, belted bias or bias tires
since it may cause dangerous
handling characteristics and lead
to an accident.
Your vehicle is equipped with “all season
tires ”which are designed to provide an
adequate measure of traction, handling
and braking performance in year-round
driving. In winter, it may be possible to
enhance performance through use of tires
designed specifically for winter drivingconditions.
If you choose to install winter tires on your
vehicle, be sure to use the correct tire size
and type. You must install four winter tires
that are of the same size, construction,
brand and load range and you should
never mix radial, belted bias or bias tires
since this may result in dangerous hand-
ling characteristics. When you choose a
tire, make sure that there is enough
clearance between the tire and vehicle
body.
Remember to drive with care at all times
regardless of the type of tires on yourvehicle. !
