roads. This may cause loss of
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 3-48.
If the rear wiper blade is frozen to the rear
window, use the rear window defogger.
Refer to “Defogger and deicer ”F 3-48.
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 3-39.
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 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, con-
struction, brand, and load range.
Mixing other sizes or construc-
tions may result in severe me-
chanical damage to the drive
train of your vehicle and may
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.
! Turbo models
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. !
Non-turbo models
Your vehicle is equipped with “all season
tires ”as original equipment, which are
designed 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 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/select lever back and forth between“ 1 ”/“ 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
slippery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT).
If your vehicle is an AT model, for
information about holding the transmission
in the 2nd position, refer to “Selection of
manual mode ”F 7-26. Driving tips

Loading your vehicle
WARNING
. Never allow passengers to ride
on a folded rear seatback, in the
trunk or in the cargo area. Doing
so may result in serious injury.
. Never stack luggage or other
cargo higher than the top of the
seatback because it could tumble
forward and injure passengers in
the event of a sudden stop or
accident. Keep luggage or cargo
low, as close to the floor aspossible.
WARNING
. When 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.
. Do 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.
. Secure lengthy items properly to
prevent them from shooting for-
ward and causing serious injury
during a sudden stop.
. Never exceed the maximum load
limit. If you do, some parts on
your vehicle can break, or it can
change the way your vehicle
handles. This could result in loss
of control and cause personal
injury. Also, overloading can
shorten the life of your vehicle.
. Do not place anything on the rear
shelf behind the rear seatback
(for 4-door) or the extended car-
go area cover (for 5-door). Such
items could tumble forward in the
event of a sudden stop or a
collision. This could cause ser- ious injury.
CAUTION
Do not carry spray cans, containers
with flammable or corrosive liquids
or any other dangerous items inside
the vehicle.
NOTE
For better fuel economy, do not carry
unneeded cargo. & Vehicle capacity weight

The load capacity of your vehicle is
determined by weight, not by available
cargo space. The maximum load you can
carry in your vehicle is shown on the
vehicle placard attached to the driver’s
side door pillar. It includes the total weight
of the driver and all passengers and their
belongings, any optional equipment such
as a roof rack or bike carrier, etc. &
GVWR and GAWR (Gross
Vehicle Weight Rating and
Gross Axle Weight Rating)
The certification label attached to the
driver ’s side doorjamb shows GVWR
(Gross Vehicle Weight Rating) and GAWR
(Gross Axle Weight Rating).
The GVW (Gross Vehicle Weight) must
never exceed the GVWR. GVW is the
combined total of weight of the vehicle,
fuel, driver, all passengers, luggage and
any optional equipment. Therefore, the
GVW changes depending on the situation.
The GVWR equals Curb Weight (actual
weight of your vehicle –including standard
equipment, fluids, emergency tools and
spare tire assembly) plus the vehicle
capacity weight. In addition, the total weight applied to
each axle (GAW) must never exceed the
GAWR. The front and rear GAWs can be
adjusted by relocating luggage inside thevehicle.
Even if the total weight of your luggage is
lower than the vehicle capacity weight,
either front or rear GAW may exceed the
GAWR, depending on the distribution of
the luggage.
When possible, the load should be evenly
distributed throughout the vehicle.
If you carry heavy loads in the vehicle, you
should confirm that GVW and front and
rear GAWs are within the GVWR and
GAWR by putting your vehicle on a
vehicle scale, found at a commercial
weighing station.
Do not use replacement tires with a lower
load range than the originals because they
may lower the GVWR and GAWR limita-
tions. Replacement tires with a higher load
range than the originals do not increase
the GVWR and GAWR limitations.

&Roof molding and crossbar
(if equipped)
CAUTION
. For cargo carrying purposes, the
roof molding must be used to-
gether with a roof crossbar kit
and the appropriate carrying at-
tachment. Otherwise, damage to
the roof or paint or a dangerous
road hazard due to loss of cargo
could result.
. When using the roof crossbar kit,
make sure that the total weight of
the crossbars, carrying attach-
ment and cargo does not exceed
the maximum load limit. Over-
loading may cause damage to the vehicle and create a safetyhazard.
Cargo can be carried after securing the
roof crossbar kit to the roof molding and
installing the appropriate carrying attach-
ment. When installing the roof crossbar
kit, follow the manufacturer ’s instructions.
When you carry cargo on the roof using
the roof crossbar kit and a carrying
attachment, never exceed the maximum
load limit as explained below. You should
also be careful that your vehicle does not
exceed the Gross Vehicle Weight Rating
(GVWR) and front and rear Gross Axle
Weight Rating (GAWR). For information
about loading cargo into or onto your
vehicle, refer to “Loading your vehicle ”
F 8-12. The maximum load limit of the
cargo, crossbars and carrying attachment
must not exceed 176 lbs (80 kg). Place
the heaviest load at the bottom, nearest
the roof, and evenly distribute the cargo.
Always properly secure all cargo. !
Installing carrying attachments on
the crossbars
When installing any carrying attachment
such as a bike carrier, ski carrier, kayak
carrier, cargo basket, etc. on the cross-
bars, follow the manufacturer ’s instruc-
tions and make sure that the attachment is
securely fixed to the crossbars. Use only
attachments designed specifically for the
crossbars. A set of the crossbars is
designed to carry loads (cargo and attach-
ment) of not more than 165 lbs (75 kg).
Before operating the vehicle, make sure
that the cargo is properly secured on theattachment.
NOTE
Remember that the vehicle ’s center of
gravity is altered with the weight of the
load on the roof, thus affecting the
driving characteristics.
Drive carefully. Avoid rapid starts, hard
cornering and abrupt stops. Crosswind
effects will be increased.

!Removal and installation of the crossbars
Each of the two roof moldings has two
mounting points for crossbars. Each
mounting point is fitted with a cover. Use
a screwdriver to remove the covers. When
installing the crossbars on the roof mold-
ing, follow the manufacturer ’s instructions. Trailer towing
Your vehicle is neither designed nor
intended to be used for trailer towing.
Therefore, never tow a trailer with yourvehicle.
SUBARU assumes no responsibility for
injuries or vehicle damage that may result
from trailer towing, from any trailer towing
equipment or from any errors or omissions
in the instructions accompanying such
equipment. SUBARU warranties do not
apply to vehicle damage or malfunction
caused by trailer towing.
