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.
yTraction 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.
NOTEy
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.
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.
– 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 Dy-
namics Control system is re-
duced and this should be taken
into account when driving the
vehicle in such a condition.

yAll 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 Dynam-
ics Control system will be unable to op-
erate correctly as intended.
y Always turn off the engine before re-
placing a tire as failure to do so may
render the Vehicle Dynamics Control
system unable to operate correctly.„ Vehicle Dynamics Control

Driving tips for AWD vehiclesAll-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 acceleration and
added engine braking force during decel-
eration.
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 fol-lowing tips in mind:
y
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, how-
ever, during extremely sharp turns or sud-
den braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an am-
ple distance from other vehicles.
y When replacing a tire, make sure you
use only the same size, construction,
brand, and load range as the original tires
listed on the tire placard. Using other sizes
or construction may result in severe me-
chanical 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.
y Always check the cold tire pressure be-
fore starting to drive. The recommended
tire pressure is provided on the tire plac-
ard, which is located under the door latch
on the driver’s side.
y Tire chains should always be placed on
the front wheels only.
y There are some precautions that you
must observe when towing your vehicle.
For detail information, see the “Towing”
section in chapter 9.

y 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 braking
or under other similar conditions.yAlways use the utmost care in
driving – overconfidence because
you are driving an All-Wheel Drive
vehicle could easily lead to a seri-
ous accident.

Driving tips
wiper blades (winter blades) during the
seasons you could have snow and sub-
zero temperatures. Blades of this type
give superior wiping performance in
snowy conditions. Be sure to use blades
that are suitable for your vehicle.NOTEWhen the season requiring non-freez-
ing type wiper blades is over, replace
them with standard wiper blades.„Corrosion protectionRefer to the “Corrosion protection” section
(chapter 10).
„Snow tires
Your vehicle is equipped with “all season
tires” as original equipment, which are de-
signed to provide an adequate measure of
traction, handling and braking perfor-
mance 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 vehicle, be sure to use the correct tire
size and type. You must install four winter
tires that are of the same size, construc-
tion, brand and load range and you should
never mix radial, belted bias or bias tires
since this may result in dangerous han-
dling characteristics. When you choose a
tire, make sure that there is enough clear-
ance between the tire and vehicle body.
Remember to drive with care at all times
regardless of the type of tires on your ve-
hicle.„Tire chainsDriving 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 sus-
pension.
When driving with tire chains, drive at
During high-speed driving, non-
freezing type wiper blades may not
perform as well as standard wiper
blades. If this happens, reduce the
vehicle speed.
y
When replacing original tires with
winter (snow) tires, make sure you
use only the same size, construc-
tion and load range as the original
tires listed on the tire placard. Us-
ing other sizes and construction
may affect speedometer/odome-
ter calibration and clearance be-
tween the body and tires. It also
may be dangerous and lead to
loss of vehicle control.yYou must install four winter tires

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 eas-
ily lead to a serious accident.„Rocking the vehicleIf you must rock the vehicle to free it from
snow, sand, or mud, depress the acceler-
ator pedal slightly and move the selector
lever back and forth between “D” and “R”
repeatedly. Do not race the engine. For
the best possible traction, avoid spinning
the wheels when trying to free the vehicle.
When the road surface is extremely slip-
pery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT).
Refer to the “Automatic transmission” sec-
tion in chapter 7 for information on holding
the transmission in 2nd position.
Loading your vehicleyNever allow passengers to ride on
a folded rear seatback or in the
cargo area. Doing so may result in
serious injury.yNever stack luggage or other car-
go higher than the top of the seat-
back because it could tumble for-
ward and injure passengers in the
event of a sudden stop or acci-
dent. Keep luggage or cargo low,
as close to the floor as possible.

yWhen you carry something inside
the vehicle, secure it whenever
you can to prevent it from being
thrown around inside the vehicle
during sudden stops, sharp turns
or in an accident.yDo not pile heavy loads on the
roof. These loads raise the vehi-
cle’s center of gravity and make it
more prone to tip over.ySecure lengthy items properly to
prevent them from shooting for-
ward and causing serious injury
during a sudden stop.yNever exceed the maximum load
limit. If you do, some parts on
your vehicle can break, or it can
change the way your vehicle han-
dles. This could result in loss of
control and cause personal injury.
Also, overloading can shorten the
life of your vehicle.yDo not place anything on the ex-
tended cargo area cover. Such
items could tumble forward in the
event of a sudden stop or a colli-
sion. This could cause serious in-
jury.

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 pneu-
matic 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 pro-
duction tires.
All passenger car tires must confirm
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 con-
ditions 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 ac-
tual conditions of their use, however,
and may depart significantly from the
norm due to variations in driving hab-
its, 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 as-
phalt and concrete. A tire marked C
may have poor traction performance.
„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 corre-
sponds 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 per-
formance on the laboratory test wheel
than the minimum required by law.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.
