Winter driving
&Operation during cold weather
Carry some emergency equipment, such
as tire chains, a window scraper, a bag of
sand, flares, a small shovel, and jumpercables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winterstarts.
Use an engine oil of proper grade and
viscosity for cold weather. Heavy summer
oil will cause harder starting.
Keep the door locks from freezing by squirting them with deicer or glycerin.
Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen,
use hot water to melt the ice, and after-
wards thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
SUBARU Windshield Washer Fluid con-
tains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the followingtable.
Washer Fluid Con- centration Freezing Temperature
30% 10.4 8F( 12 8C)
50% 48F( 20 8C)
100%
49 8F( 45 8C)
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block thenozzles.
CAUTION
Adjust the washer fluid concentra-
tion appropriately for the outside
temperature. If the concentration is
inappropriate, sprayed washer fluid
may freeze on the windshield and
obstruct your view, and the fluid
may freeze in the reservoir tank.
! Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery anddangerous.
While warming up the vehicle before
driving, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has
accumulated under the fenders to avoid
making steering difficult. During severe

winter driving, stop when and where it is
safe to do so and check under the fenders
periodically. !Parking in cold weather
Do not use the parking brake when
parking for long periods in cold weather
since it could freeze in that position.
Instead, observe the following.
1. Place the shift lever in “1 ” or “R ” for
manual transmission vehicles, and in “P ”
for automatic transmission vehicles.
2. Use tire stops under the tires to
prevent the vehicle from moving.
When the vehicle is parked in snow or
when it snows, raise the wiper blades off
the glass to prevent damage to them.
When the vehicle has been left parked
after use on roads heavily covered with
snow, or has been left parked during a
snowstorm, icing may develop on the
brake system, which could cause poor
braking action. Check for snow or ice
buildup on the suspension, disc brakes
and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it,
being careful not to damage the disc
brakes and brake hoses and ABS har-ness.WARNING
Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle if you park
the vehicle in snow with the enginerunning.
! Refueling in cold weather
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an
antifreeze additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty.
If your SUBARU is not going to be used
for an extended period, it is best to have
the fuel tank filled to capacity. & Driving on snowy and icy roads
To prevent skidding and slipping, avoid
sudden braking, abrupt acceleration, high-
speed driving, and sharp turning when
driving on snowy or icy roads.
Always maintain ample distance between
your vehicle and the vehicle ahead of you to avoid the need for sudden braking.
To supplement the foot brake, use the
engine brake effectively to control the
vehicle speed. (Shift into a lower gear
when necessary.)
Avoid shifting down abruptly. Such beha-
vior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) en-
hances your vehicle
’s braking perfor-
mance on snowy and icy roads. Refer tothe “ABS (Anti-lock Brake System) ”sec-
tion in chapter 7 for information on braking
on slippery surfaces.
NOTE
The following tires are summer tires.
Compared with winter and all-season
tires, summer tires give significantly
less grip on snowy and icy road
surfaces. Avoid driving on snowy and
icy road surface with summer tires. . 225/45R17 tires for WRX-STI
WARNING
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of
vehicle control. Driving tips

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 Sedan) or the extended cargo
area cover (for Wagon). 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 trailer hitch, roof rack or bike carrier,
etc., and the tongue load of a trailer. Driving tips

& GVWR and GAWR (Gross
Vehicle Weight Rating and
Gross Axle Weight Rating)
The certification plate 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, any
optional equipment and trailer tongue
load. Therefore, the GVW changes de-
pending on the situation. The GVWR
equals Curb Weight (actual weight of yourvehicle –including standard equipment,
fluids, emergency tools and spare tire
assembly) plus the vehicle capacityweight. 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 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 carrying
attachment. 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 explained in the following. 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

for your hitch and trailer.
WARNING
Always use safety chains between
your vehicle and the trailer. Towing a
trailer without safety chains could
create a traffic safety hazard if the
trailer separates from the hitch due
to coupling damage or hitch balldamage.
! Side mirrors
After hitching a trailer to your vehicle,
check that the standard side mirrors
provide a good rearward field of view
without significant blind spots. If significant
blind spots occur with the vehicle ’s stan-
dard side mirrors, use towing mirrors that conform with Federal, state/province and/
or other applicable regulations. !
Trailer lights
Connection of trailer lights to your vehi- cle ’s electrical system requires modifica-
tions to the vehicle ’s lighting circuit to
increase its capacity and accommodate
wiring changes. To ensure the trailer lights
are connected properly, please consult
your SUBARU dealer. Check for proper
operation of the turn signals, the brake
lights and parking lights each time you
hitch up.
CAUTION
Direct splicing or other improper
connection of trailer lights may
damage your vehicle ’s electrical
system and cause a malfunction of
your vehicle ’s lighting system.
! Tires
Make sure that all the tires on your vehicle
are properly inflated to the pressure
specified on the tire placard located on
the left center pillar of your vehicle.
Trailer tire condition, size, load rating and
proper inflation pressure should be in
accordance with the trailer manufacturer ’s specifications.
In the event your vehicle gets a flat tire
when towing a trailer, ask a commercial
road service to repair the flat tire.
If you carry a regular size spare tire in your
vehicle or trailer as a precaution against
getting a flat tire, be sure that the spare
tire is firmly secured.
WARNING
Never tow a trailer when the tem-
porary spare tire is used. The tem-
porary spare tire is not designed to
sustain the towing load. Use of the
temporary spare tire when towing
can result in failure of the spare tire
and/or less stability of the vehicle.
& Trailer towing tips
CAUTION
. Never exceed 45 mph (72 km/h)
when towing a trailer in hilly
country on hot days.
. When towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent from normal operation. For Driving tips

CAUTION
. Never over tighten the oil filter
because that can result in an oil leak.
. Thoroughly wipe off any engine
oil that has spilled over the
exhaust pipe and/or under-cover.
If spilled oil is not promptly
wiped up, the oil could cause afire.
11. Reinstall under cover.
12. Pour engine oil through the filler neck. Oil capacity (guideline): 4.2 US qt (4.0 liters, 3.5 Imp qt)
The oil quantity indicated above is only guideline.
The necessary quantity of oil depends on
the quantity of oil that has been drained.
The quantity of drained oil differs slightly
depending on the temperature of the oil and the time the oil is left flowing out. After
refilling the engine with oil, therefore, you
must use the dipstick to confirm that the
level is correct.
13. Start the engine and make sure that no
oil leaks appear around the filter
’s rubber
seal and drain plug.
14. Run the engine until it reaches the
normal operating temperature. Then stop
the engine and wait a few minutes to allow
the oil drain back. Check the oil level
again and if necessary, add more engineoil.
CAUTION
Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire.

13-6Consumer information and Reporting safety defects
! Vehicle placard
The vehicle placard is affixed to the driver ’s side B-pillar.
Example:
The vehicle placard shows original
tire size, recommended cold tire infla-
tion pressure on each tire at max-
imum loaded vehicle weight, seating
capacity and loading information. ! Adverse safety consequences
of under-inflation
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to rapidly
become hot. A sharp increase in
temperature could cause tread se-
paration, and failure of the tire(s).
Possible resulting loss of vehicle
control could lead to an accident. ! Measuring and adjusting air
pressure to achieve proper in-
flation
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are cold.
Use a pressure gauge to adjust the
tire pressures to the specific values.
Driving even a short distance warms
up the tires and increases the tire
pressures. Also, the tire pressures are affected by the outside temperature. It
is best to check tire pressure outdoors
before driving the vehicle. When a tire
becomes warm, the air inside it
expands, causing the tire pressure to
increase. Be careful not to mistakenly
release air from a warm tire to reduce
its pressure. &
Glossary of tire terminology
. Cold tire pressure
The pressure in a tire that has been
driven less than 1 mile or has been
standing for three hours or more. . Maximum inflation pressure
The maximum cold inflation pressure
to which a tire may be inflated. . Recommended inflation pres-
