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 wiper blades are frozen to the windshield or rear
window, 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. If your vehicle is equipped with
a wiper deicer, it is helpful to thaw the windshield wiper
blades. To thaw out the rear wiper blade, use the rear
window defogger.
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.
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 sub-zero temperatures. Blades of this type
give superior wiping performance in snowy conditions.
Be sure to use blades that are suitable for your vehi- cle. „

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

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. yDo 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.
The optional 215/45R17 tires for the WRX are summer
tires. Compared with winter and all-season tires, sum-
mer 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 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. T

dent.
Your vehicle is equipped with “summer tires” as origi-
nal 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 rec-
ommended when driving with such road 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).
When a temporary spare tire is on a front wheel, re-
place the temporary spare tire with the rear tire on the
same side of the vehicle, and then fit chains on the
front tires.
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.
Tire chains cannot be used on tires listed below
because of lack of clearance between the tires
and vehicle body.y

„ Rocking the vehicle
If you must rock the vehicle to free it from snow, sand,
or mud, depress the accelerator 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 slippery, 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” section in chap-
ter 7 for information on holding the transmission in 2nd position.Loading your vehicle
yNever allow passengers to ride on the folded
rear seatback, in the trunk or in the cargo area.
Doing so may result in serious injury. y 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 lug-
gage or cargo low, as close to the floor as pos-
sible.

Driving tips
y
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. y Do not pile heavy loads on the roof. These
loads raise the vehicle’s center of gravity and
make it more prone to tip over. y Secure lengthy items properly to prevent
them from shooting forward and causing seri-
ous injury during a sudden stop. y 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 per-
sonal injury. Also, overloading can shorten the
life of your vehicle. y
Do not place anything on the rear shelf be-
hind the rear seatback (for sedan) or the ex-
tended luggage cover (for wagon). Such items
could tumble forward in the event of a sudden
stop or a collision. This could cause serious in-
jury.
Do not carry spray cans, containers with flam-
mable or corrosive liquids or any other danger-
ous 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 ve-
hicle placard attached to the driver’s side door pillar. It
includes the total weight of driver and all passengers
and their belongings, any optional equipment such as
a trailer hitch, roof rack or bike carrier, etc., and the
tongue load of a trailer. „

door jamb shows GVWR (Gross Vehicle Weight Rat-
ing) 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, any op-
tional equipment and trailer tongue load. Therefore,
the GVW changes depending on the situation. The
GVWR equals Curb Weight (actual weight of your ve-
hicle – including standard equipment, fluids, emergen-
cy tools and spare tire assembly) plus the vehicle ca-
pacity 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 in-side the vehicle.
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 con-
firm that GVW and front and rear GAWs are within the
GVWR and GAWR by putting your vehicle on a vehi-
cle 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 limitations. Replacement tires with a high-
er load range than the originals do not increase the
GVWR and GAWR limitations. „
Roof rail and crossbar (if equipped)
1) Crossbar kit
The roof rail is not designed to carry cargo by itself.
Cargo can be carried after securing the roof crossbar
kit to the roof rail and installing the appropriate carry-
ing attachment. When installing the roof crossbar kit,
follow the manufacturer’s instructions.

When you carry cargo on the roof using the roof cross-
bar kit and a carrying attachment, never exceed the
maximum load limit 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). See the “Loading
your vehicle” section in this chapter for information on
loading cargo into or onto your vehicle. The maximum
load limit of the cargo, crossbars and carrying attach-
ment must not exceed 100 lbs (45 kg). Place the
heaviest load at the bottom, nearest the roof, and
evenly distribute the cargo. Always properly secure all
cargo.
yFor cargo carrying purposes, the roof rail
must be used together with a roof crossbar kit
and the appropriate carrying attachment. The
roof rail must never be used alone to carry car-
go. Otherwise, damage to the roof or paint or a
dangerous road hazard due to loss of cargo
could result.y When using the roof crossbar kit, make sure
that the total weight of the crossbars, carrying
attachment and cargo does not exceed the
maximum load limit. Overloading may cause
damage to the vehicle and create a safety haz-
ard.
T Installing carrying attachments on the cross-
bars
When installing any carrying attachment such as a
bike carrier, ski carrier, kayak carrier, cargo basket,
etc. on the crossbars, follow the manufacturer’s in-
structions and make sure that the attachment is se-
curely fixed to the crossbars. Use only attachments
designed specifically for the crossbars. A set of the
crossbars is designed to carry loads (cargo and at-
tachment) of not more than 100 lbs (45 kg). Before
operating the vehicle, make sure that the cargo is
properly secured on the attachment.
NOTE
Remember that the vehicle’s center of gravity is al-
tered 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 in-
creased. T Removal and installation of the crossbars
The crossbars can be removed when you do not use
the roof to carry cargo.
