Starting and operating
Vehicle Dynamics Control system (if
equipped)
Always use the utmost care in driving – over-
confidence because you are driving with a Ve-
hicle Dynamics Control system equipped vehi-
cle could easily lead to a serious accident.
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 addition, vehicle speed should
be reduced considerably. Simply having a Vehi-
cle Dynamics Control system does not guaran-
tee that the vehicle will be able to avoid acci-
dents in any situation.y Activation of the Vehicle Dynamics Control
system is an indication that the road being trav-
elled 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 components, steering
components, or an axle are removed from a ve-
hicle equipped with Vehicle Dynamics Control,
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 Vehicle Dy-
namics 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.
– 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 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 eva-
sive maneuver, the Vehicle Dynamics Control system

adjusts the engine’s output and the wheels’ respective
braking forces to help maintain traction and directional
control. yTraction 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 Vehicle Dynamics 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 op-
erations. Activation of this function is shown by flash-
ing of the Vehicle Dynamics Control operation indica-
tor light.
NOTE y Slight twitching of the brake pedal may be felt
when the Vehicle Dynamics Control system oper-
ates; a small degree of vehicle or steering wheel
shaking may also be noticed in this situation.
These are normal characteristics of Vehicle Dy-
namics Control 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 Vehicle Dynamics Control system
and is normal. y Depending on the timing of activation 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 consequence of the
Vehicle Dynamics Control operational check and
is normal. y In the circumstances listed below, the vehicle
may be more unstable than it feels to the driver.

fore operate. Such operation does not indicate a system fault. yon gravel-covered or rutted roads

„Snow tires
yWhen replacing original tires with winter
(snow) tires, make sure you use only the same
size, construction and load range as the origi-
nal tires listed on the tire placard. Using other
sizes and construction may affect speedome-
ter/odometer calibration and clearance be-
tween the body and tires. It also may be danger-
ous and lead to loss of vehicle control. y You must install four winter tires that are of
the same size, construction, brand, and load
range. Mixing other sizes or constructions may
result in severe mechanical damage to the drive
train of your vehicle and may affect ride, han-
dling, braking and speedometer/odometer cali-
bration. It also may be dangerous and lead to
loss of vehicle control. y Do not use a combination of radial, belted
bias or bias tires since it may cause dangerous
handling characteristics and lead to an acci-
dent.
Your vehicle is equipped with “all season tires” as orig-
inal equipment, which are designed to provide an ad- equate measure of traction, handling and braking per-
formance in year-round driving. In winter, it may be
possible to enhance performance through use of tires
designed specifically for winter driving conditions.
When you choose to install winter tires on your vehi-
cle, 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 handling 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. „
Tire chains
Driving on snowy grades or icy roads may require the
use of tire chains, in which case put the chains on the
front wheels only. Use only SAE class S type chains
that are of the correct size for your tires so as not to
damage the vehicle body or suspension.
When driving with tire chains, drive at speeds below
19 mph (30 km/h).
Always use the utmost care when driving with tire
chains – overconfidence because you are driving with
tire chains could easily lead to a serious accident.

Tires and wheels „Types of tires
You should be familiar with type of tires present on your vehicle. T All season tires
The factory-installed tires on your new vehicle are all
season tires.
All season tires are designed to provide an adequate
measure of traction, handling and braking perfor-
mance in year-round driving including snowy and icy
road conditions. However all season tires do not offer
as much traction performance as winter (snow) tires in
heavy or loose snow or on icy roads.
All season tires are identified by “ALL SEASON” and/
or “M+S” (Mud & Snow) on the tire sidewall. T Summer tires
Summer tires are high-speed capability tires best suit-
ed for highway driving under dry conditions.
Summer tires are inadequate for driving on slippery
roads such as on snow-covered or icy roads.
If you drive your vehicle on snow-covered or icy roads,
we strongly recommend the use of winter (snow) tires.
When installing winter tires, be sure to replace all four
tires. T
Winter (snow) tires
Winter tires are best suited for driving on snow-cov-
ered and icy roads. However winter tires do not per-
form as well as summer tires and all season tires on
roads other than snow-covered and icy roads. „ Tire inspection
Check on a daily basis that the tires are free from se-
rious damage, nails, and stones. At the same time,
check the tires for abnormal wear.
Contact your SUBARU dealer immediately if you find
any problem.
NOTE y When the wheels and tires strike curbs or are
subjected to harsh treatment as when the vehicle
is driven on a rough surface, they can suffer dam-
age that cannot be seen with the naked eye. This
type of damage does not become evident until
time has passed. Try not to drive over curbs, pot-
holes or on other rough surfaces. If doing so is un-
avoidable, keep the vehicle’s speed down to a
walking pace or less, and approach the curbs as
squarely as possible. Also, make sure the tires are
not pressed against the curb when you park thevehicle. y If you feel unusual vibration while driving or find

Consumer information and Reporting safety defects
– CONTINUED –
Uniform tire quality grading stan-
dards
This information indicates the relative perfor-
mance of passenger car tires in the area of
treadwear, traction, and temperature resistance.
This is to aid the consumer in making an in-
formed choice in the purchase of tires.
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature 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 confirm to Federal
Safety Requirements in addition to these grades. „Treadwear
The treadwear grade is a comparative rating based on the wear rate of the tire when tested
under controlled conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one
and one-half (1-1/2) times as well on the govern-
ment course as a tire graded 100. The relative
performance of tires depends upon the actual
conditions of their use, however, 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, C
The 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 mea-
sured under controlled conditions on specified
government test surfaces of asphalt and con-
crete. A tire marked C may have poor traction
performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction
