it more prone to tip over. If you must rock the vehicle to free it from 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 withthe transmission in 2nd than 1st (both for MT and
AT). Never equip your vehicle with tires larger than
those specified in this manual. Frequent driving of an AWD vehicle under hard-
driving conditions such as rough roads or off roads
will necessitate more frequent replacement of engine
oil, brake fluid and transmission oil than that specified
in the maintenance schedule described in the “War -
ranty and Maintenance Booklet ”.
Remember that damage done to your Subaru while
operating it off-road and not using common sense
precautions such as those listed above is not eligi-ble for warranty coverage. Winter driving

Operation during cold weather
Carry some emergency equipment, such as tire
chains, a window scraper, a bag of sand, flares, asmall shovel, and jumper cables.
Check the battery and cables. Cold temperatures
reduce battery capacity. The battery must be in
good condition to provide enough power for cold
winter starts.
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 sepa-
rate the rubber weather strips around the door. If the
door is frozen, use hot water to melt the ice, and af-
terwards thoroughly wipe the water away. Use a windshield washer fluid that contains an anti-
freeze solution. Do not use engine antifreeze or oth-
er substitutes because they may damage the paintof the vehicle.
Before driving your vehicle
Before entering the vehicle, remove any snow or ice
from your shoes because that could make the ped-
als slippery and dangerous.
While warming up the vehicle before driving, check that the accelerator pedal, brake pedal, and all oth-
er controls operate smoothly. Clear away ice and snow that has accumulated un-
der the fenders to avoid making steering difficult.
During severe winter driving, stop when and where itis safe to do so and check under the fenders peri-
odically.
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 trans-
mission vehicles, and in “P” for automatic transmis-
sion vehicles.
2. Use tire stops under the tires to prevent the ve-
hicle from moving.
When the vehicle is parked in snow or when it
snows, raise the wiper blades off the glass to pre-vent 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 onthe brake system, which could cause poor braking
action. Check for snow or ice buildup on the sus-
pension, disc brakes and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it, being care-ful not to damage the disc brakes and brake hoses
and ABS harness.

WARNING
Snow can trap dangerous exhaust gases under your vehicle. Keep snow clear of the
exhaust pipe and from around your vehicle ifyou park the vehicle in snow with the engine running.
Refueling in cold weather
To help prevent moisture from forming in the fuel
system and the risk of its freezing, use of an anti-
freeze additive in the fuel tank is recommended dur-
ing 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 ex-
tended 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 ve-
hicle and the vehicle ahead of you to avoid the needfor 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 behavior cancause the wheels to lock, possibly leading to loss of
vehicle control.
An anti-lock brake system (ABS) e
nhances your
vehicle’ s braking performance on snowy and icy
roads. Refer to the “ABS (Anti-Lock Brake System) ”
section in chapter 7 for information on braking on
slippery surfaces. NOTE The optional 17-inch tires for the WRX are sum- mer tires. Compared with winter and all-season tires, summer tires give significantly less grip on
snowy and icy road surfaces. Avoid driving onsnowy and icy road surface with summer tires.

WARNING
Do not use the cruise control on slippery roads such as snowy or icy roads. This may
cause loss of vehicle control.
Wiper operation when snowing
Before driving in cold weather, make sure the wiper
blades are not frozen to the windshield or rear win-
dow. If the wiper blades are frozen to the windshield
or rear window, use the defroster with the airflow
control dial in the “t ” 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 controldial in “t ” 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 car 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 perfor-
mance in snowy conditions. Be sure to use blades
that are suitable for your vehicle.
Corrosion protection
Refer to the “Corrosion protection ” section (chapter
10). 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 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 dan-

gerous and lead to loss of vehicle control. You must install four winter tires that are of
the same size, construction, brand, and loadrange. Mixing 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 calibration. It also may be danger-ous and lead to loss of vehicle control. Do not use a combination of radial, belted
bias or bias tires since it may cause danger-ous handling characteristics and lead to an accident.
Your vehicle is equipped with “all season tires ” as
original equipment, which are designed to provide
an adequate measure of traction, handling and
braking performance in year-round driving. In winter,
it may be possible to enhance performance through
use of tires designed specifically for winter drivingconditions.
The optional 17-inch tires for the WRX are summer
tires. 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 ve-
hicle, be sure to use the correct tire size and type.
You must install four winter tires that are of the samesize, construction, brand and load range and you
should never mix radial, belted bias or bias tires
since this may result in dangerous handling charac-
teristics. When you choose a tire, make sure that
there is enough clearance between the tire and ve-
hicle 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 asnot 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 onthe same side of the vehicle, and then fit chains on
the front tires.
Always use the utmost care when driving with tire

Parking brake stroke
HB4001CA
Check the parking brake stroke according to the
maintenance schedule in the “Warranty and Mainte-
nance Booklet ”. When the parking brake is properly
adjusted, braking power is fully applied by pulling
the lever up seven to eight notches gently but firmly(about 44 lb, 196 N, 20 kg). If the parking brake le-
ver stroke is not within the specified range, have the brake system checked and adjusted at your
SUBARU dealer. Tires and wheels
Types of tires
All season tires
All season tires are designed to provide an ade-
quate measure of traction, handling and braking
performance in year-round driving including snowy
and icy road conditions. However all season tires do
not have adequate traction performance compared
with winter (snow) tires in heavy or loose snow or on
icy road.
All season tires are identified by “ALL SEASON ”
and/or “M+S” (Mud & Snow) on the tire sidewall.
Summer tires
Summer tires are high-speed capability tires best
suited for highway driving under dry conditions.
Summer tires are inadequate for driving on slippery
roads such as on snow-covered or icy roads.
If you drive your vehicle on snow-covered or icy
roads, we strongly recommend the use of winter
(snow) tires.
When installing winter tires, be sure to replace all
four tires.
Winter (snow) tires
Winter tires are best suited for driving on snow-cov-

ered and icy roads. However winter tires do not
have adequate performance compared with sum-
mer tires and all season tires on roads other than
snow-covered and icy roads. Tire inspection
Check on a daily basis that the tires are free from serious damage, nails, and stones. At the same
time, check the tires for abnormal wear.
Contact your SUBARU dealer immediately if you find
any problem. NOTE When the wheels and tires strike curbs or are
subjected to harsh treatment as when the vehicle is driven on a rough surface, they can suffer
damage that cannot be seen with the naked eye.This type of damage does not become evident
until time has passed. Try not to drive over
curbs, potholes or other rough surface. If doingso is unavoidable, keep the vehicle ’s speed
down to a walking pace or less, and approach
the curbs as squarely as possible. Also, makesure the tires are not pressed against the curbswhen you park the vehicle. If you feel unusual vibration while driving or
find it difficult to steer the vehicle in a straight line, one of the tires and/or wheels may be dam-aged. Drive slowly to the nearest authorized
SUBARU dealer and have the vehicle inspected.
Tire pressures and wear
Maintaining the correct tire pressures helps to maxi-
mize the tires ’ service lives and is essential for good
running performance. Check and, if necessary, ad-
just the pressure of each tire (including the spare) at least once a month (for example, during a fuel stop)
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 values shown on the tire placard. The tire plac-
ard is located on the door pillar on the driver ’s side.
