WARNING
Continued driving with the AWD
warning light flashing can lead to
powertrain damage. If the AWD
warning light flashes, promptly park
in a safe place then check whether
all four tires are the same diameter
and whether any of the tires has a
puncture or has lost air pressure for
some other reason.
The All-Wheel Drive warning light comes
on when the ignition switch is turned to the
“ ON ”position and goes out after the
engine has started.
! For 5-speed automatic transmis-
sion vehicles
This light flashes if the vehicle is driven
with tires of different diameters fitted on its
wheels or with the air pressure exces-
sively low in any of its tires.
! For 4-speed automatic transmis-
sion vehicles
This light comes on when All-Wheel Drive
is disengaged and the drive mechanism is
switched to Front Wheel Drive for main- tenance or similar purposes.

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.
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.

Vehicle Dynamics Control system can
facilitate the following operations:
. a standing start on a steeply sloping
road with a snowy, gravel-covered, or
otherwise slippery surface
. 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.
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 indicator light goes off.
With the Vehicle Dynamics Control system
deactivated, traction and stability en-
hancement offered by Vehicle Dynamics
Control system is unavailable. Therefore
you should not deactivate the Vehicle
Dynamics Control system except under
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
switch. To make the switch usable
again, turn the ignition switch to the
OFF position and restart the engine.
. When the switch is pressed to
deactivate the Vehicle Dynamics Con-
trol system, the vehicle ’s running per-
formance is comparable with that of a
vehicle that does not have a Vehicle
Dynamics Control system. Do not de-
activate the Vehicle Dynamics Control system except when absolutely neces-
sary.

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 vehicle and may affect ride, handling,
braking, speedometer/odometer calibra-
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, see “Towing”sec-
tion in chapter 9.

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 driving
conditions.
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 your
vehicle.
! OUTBACK models
WARNING
.When replacing original tires with
winter (snow) tires, make sure
you use only the same size and
construction as recommended.
Using other sizes or construction
may affect speedometer/od-
ometer calibration and clearance between the body and tires. It
also may be dangerous and lead
to loss of vehicle control.
. You must install four winter tires
that are of the same size, circum-
ferences, construction, brand,

affect ride, handling, braking and
speedometer/odometer 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

Consumer information and Reporting safety defects
Uniform tire quality grading
standardsThis information indicates the relative
performance of passenger car tires in
the area of treadwear, traction, and
temperature resistance. This is to aid
the consumer in making an informed
choice in the purchase of tires.
Quality grades can be found where
applicable on the tire sidewall be-
tween tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Tem-
perature A
The quality grades apply to new
pneumatic tires for use on passenger
cars. However, they do not apply to
deep tread, winter type snow tires,
space-saver or temporary use spare
tires, tires with nominal rim diameters
of 12 inches or less, or to some limited
production tires.
All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.
& TreadwearThe treadwear grade is a comparative
rating based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course.
For example, a tire graded 150 would
wear one and one-half (1-1/2) times
as well on the government course as
a tire graded 100. The relative perfor-
mance of tires depends upon the
actual conditions of their use, how-
ever, and may depart significantly
from the norm due to variations in
driving habits, service practices and
differences in road characteristics and
climate.&Traction AA, A, B, CThe traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire ’s ability to
stop on wet pavement as measured
under controlled conditions on speci-
fied government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perfor-
mance.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning, or
peak traction characteristics.
& Temperature A, B, CThe temperature grades are A (the
highest), B, and C, representing the
tire ’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel. Sustained high tempera-
ture can cause the material of the tire
to degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C
corresponds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standards No. 109. Grades B
and A represent higher levels of
performance on the laboratory test
wheel than the minimum required by
