&Driving when tired or sleepy
WARNING
When you are tired or sleepy, your
reaction time will be delayed and
your perception, judgment and at-
tentiveness will be impaired. If you
drive when tired or sleepy, your,
your passengers ’and other per-
sons ’chances of being involved in
a serious accident may increase.
Please do not continue to drive but
instead find a safe place to rest if you
are tired or sleepy. On long trips, you
should make periodic rest stops to refresh
yourself before continuing on your journey.
When possible, you should share the
driving with others.
& Modification of your vehicle
CAUTION
Your vehicle should not be modified
other than with genuine SUBARU
parts and accessories. Other types
of modifications could affect its
performance, safety or durability,
and may even violate governmental
regulations. In addition, damage or performance problems resulting
from modification may not be cov-
ered under warranties.
& Car phone/cell phone and driving
CAUTION
Do not use a car phone/cell phone
while driving; it may distract your
attention from driving and can lead
to an accident. If you use a car
phone/cell phone, pull off the road
and park in a safe place before
using your phone. In some States/
Provinces, only hands-free phones
may legally be used while driving.
& Driving vehicles equipped
with navigation system
WARNING
Do not allow the monitor to distract
your attention from driving. Also, do
not operate the controls of the
navigation system while driving.
The loss of attention to driving
could lead to an accident. If you wish to operate the controls of the
navigation system, first take the
vehicle off the road and stop it in a
safe place.
& Driving with pets
Unrestrained pets can interfere with your
driving and distract your attention from
driving. In a collision or sudden stop,
unrestrained pets or cages can be thrown
around inside the vehicle and hurt you or
your passengers. Besides, the pets can
be hurt under these situations. It is also for
their own safety that pets should be
properly restrained in your vehicle. Re-
strain a pet with a special traveling
harness which can be secured to the rear
seat with a seatbelt or use a pet carrier
which can be secured to the rear seat by
routing a seatbelt through the carrier ’s
handle. Never restrain pets or pet carriers
in the front passenger ’s seat. For further
information, consult your veterinarian,
local animal protection society or petshop.

Seatbelts &Seatbelt safety tips
WARNING
. All persons in the vehicle should
fasten their seatbelts BEFORE
the vehicle starts to move. Other-
wise, the possibility of serious
injury becomes greater in the
event of a sudden stop or acci-dent.
. All belts should fit snugly in order
to provide full restraint. Loose
fitting belts are not as effective in
preventing or reducing injury.
. Each seatbelt is designed to
support only one person. Never
use a single belt for two or morepersons –even children. Other-
wise, in an accident, serious
injury or death could result.
. Replace all seatbelt assemblies
including retractors and attach-
ing hardware worn by occupants
of a vehicle that has been in a
serious accident. The entire as-
sembly should be replaced even
if damage is not obvious.
. Put children aged 12 and under in the rear seat properly restrained
at all times. The SRS airbag
deploys with considerable speed
and force and can injure or even
kill children, especially if they are
12 years of age and under and
are not restrained or improperly
restrained. Because children are
lighter and weaker than adults,
their risk of being injured from
deployment is greater. For that
reason, we strongly recommend
that ALL children (including
those in child seats and those
that have outgrown child re-
straint devices) sit in the REAR
seat properly restrained at all
times in a child restraint device
or in a seatbelt, whichever is
appropriate for the child
’s height
and weight.
Secure ALL types of child re-
straint devices (including for-
ward facing child seats) in the
REAR seats at all times.
NEVER INSTALL A REARWARD
FACING CHILD SEAT IN THE
FRONT SEAT. DOING SO RISKS
SERIOUS INJURY OR DEATH TO
THE CHILD BY PLACING THECHILD ’S HEAD TOO CLOSE TO
THE SRS AIRBAG. According to accident statistics,
children are safer when properly
restrained in the rear seating
positions than in the front seat-
ing positions. For instructions
and precautions concerning the
child restraint system, refer to“
Child restraint systems ”F 1-21.
Your vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seatbelt by the front
passenger when any of the SRS frontal,
side and curtain airbags deploy. ! Infants or small children
Use a child restraint system that is
suitable for your vehicle. Refer to “Child
restraint systems ”F 1-21.
! Children
If a child is too big for a child restraint
system, the child should sit in the rear seat
and be restrained using the seatbelts.
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front
seating positions. Never allow a child to
stand up or kneel on the seat.
If the shoulder portion of the belt crosses
the face or neck, adjust the shoulder belt
anchor height (window-side seating posi- Seat, seatbelt and SRS airbags

7-28Starting and operating
Vehicle Dynamics Control system
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
system, winter tires should be
used when driving on snow-cov-
ered or icy roads; in addition,
vehicle speed should be reduced
considerably. Simply having a
Vehicle Dynamics Control sys-
tem 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, have an inspection of
that system performed by an
authorized SUBARU dealer.
. 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 Con- trol system is reduced and
this should be taken into ac-
count when driving the vehi-
cle in such a condition.
. If non-matching tires are used,
the Vehicle Dynamics Control
system may not operate cor-
rectly.
. The Vehicle Dynamics Control
system helps prevent unstable
vehicle motion such as skidding
using control of the brakes and
engine power. Do not turn off the
Vehicle Dynamics Control sys-
tem unless it is absolutely ne-
cessary. If you must turn off the
Vehicle Dynamics Control sys-
tem, drive very carefully based
on the road surface 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.

8-8Driving tips
vehicle control.
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’s intake system and may
hinder the airflow, which could re-
sult in engine shutdown or evenbreakdown.
! Wiper operation when snowing
Before driving in cold weather, make sure
the wiper blades are not frozen to the
windshield or rear window.
If the front wiper blades are frozen to the
windshield, use the defroster with the
airflow control dial in the “
”position
and the temperature control dial set for
maximum warmth until the wiper blades
are completely thawed out. For details,
refer to the following section. . For the manual climate control system,
refer to “Defrosting or defogging the
windshield ”F 4-5.
. For the automatic climate control sys-
tem, refer to “Control panel ”F 4-8.
If your vehicle is equipped with a wind-
shield wiper deicer, it is helpful to thaw the
windshield wiper blades. Refer to “Defog- ger and deicer
”F 3-45.
If the rear wiper blade is frozen to the rear
window, use the rear window defogger.
Refer to “Defogger and deicer ”F 3-45.
When driving in snow, if frozen snow starts
to stick on the surface of the windshield
despite wiper operation, use the defroster
with the airflow control dial in “
”and the
temperature control dial set for maximum
warmth. After the windshield gets warmed
enough to melt the frozen snow on it,
wash it away using the windshield washer.
Refer to “Washer ”F 3-36.
Snow stuck on the wiper arm prevents the
wiper from working effectively. If snow is
stuck on the wiper arm, pull off the road to
a safe place, then remove it. If you stop
the vehicle at road side, use the hazard
warning flasher to alert other drivers.
We recommend use of non-freezing type
wiper blades (winter blades) during the
seasons you could have snow and freez-
ing temperatures. Blades of this type give
superior wiping performance in snowy
conditions. Be sure to use blades that
are suitable for your vehicle.
CAUTION
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.
NOTE
When the season requiring non-freez-
ing type wiper blades is over, replace
them with standard wiper blades. & Corrosion protection
Refer to “Corrosion protection ”F 10-4.
& Snow tires
WARNING
. When replacing original tires with
winter (snow) tires, make sure
you use only tires of the same
size, circumference, construc-
tion, brand (tread pattern), speed
symbol and load index as the
original tires listed on the tire
placard. Using tires of other sizes
or constructions may affect
speedometer/odometer calibra-
tion 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-
ference, construction, manufac-
turer, brand (tread pattern), de-
gree of wear, speed symbol and
load index. Mixing tires of other
sizes or constructions may result
in severe mechanical damage to
the drive train of your vehicle and
may affect ride, handling, braking
and speedometer/odometer cali-
bration. 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 “summer
tires ”as original equipment, which are
inadequate for driving on slippery roads
such as on snow-covered or icy roads.
Compared with winter and all-season
tires, summer tires give significantly less
grip on snowy and icy road surfaces.
Therefore, use of winter tires is strongly
recommended when driving with such
road 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 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.
& Tire chains
CAUTION
Tire chains cannot be used on your
Impreza, WRX and STI because of
the lack of clearance between the
tires and vehicle body.
& Rocking the vehicle
If you must rock the vehicle to free it from
snow, sand, or mud, depress the accel-
erator pedal slightly and move the shift
lever back and forth between “1 ” 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
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st.
