Driving tips for AWD vehicles
All-Wheel Drive distributes the engine
power to all four wheels. AWD vehicles
provide better traction when driving on
slippery, wet or snow-covered roads and
when moving out of mud, dirt and sand. By
shifting power between the front and rear
wheels, SUBARU AWD can also provide
added traction during acceleration and
added engine braking force during decel-
eration.
Therefore, your SUBARU AWD vehicle
may handle differently than an ordinary
two wheel drive vehicle and it contains
some features unique to AWD. For safety
purposes as well as to avoid damaging
the AWD system, you should keep the fol- lowing tips in mind:
An AWD vehicle is better able to climb
steeper roads under snowy or slippery
conditions than a two wheel drive vehicle.
There is little difference in handling, how-
ever, during extremely sharp turns or sud-
den braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an am-
ple distance from other vehicles.
When replacing a tire, make sure you
use only the same size, construction,
brand, and load range as the original tires
listed on the tire placard. Using other siz-
es, circumference or construction may re-
sult in severe mechanical damage to the
drive train of your vehicle and may affect
ride, handling, braking, speedometer/
odometer calibration, and clearance be-
tween the body and tires. It also may be
dangerous and lead to loss of vehicle con-
trol.
If you use a temporary spare tire to re-
place a flat tire, be sure to use the original
temporary spare tire stored in the vehicle.
Using other sizes may result in severe
mechanical damage to the drive train of
your vehicle.
Always check the cold tire pressure be-
fore starting to drive. The recommended
tire pressure is provided on the tire plac-
ard, which is located under the door latch on the driver
s side.
Tire chains should always be placed on
the front wheels only.
There are some precautions that you
must observe when towing your vehicle.
For detail information, see the Towing
section in chapter 9.
800004
Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden braking
or under other similar conditions.
Always use the utmost care in
driving overconfidence because
you are driving an All-Wheel Drive
vehicle could easily lead to a seri-
ous accident.

8-6 Driving tips
Off road drivingAll AWD models except
OUTBACK SPORT and vehi-
cles with 17 inch tires
Your AWD vehicle is neither a convention-
al off-road vehicle nor an all terrain vehi-
cle. It is a passenger vehicle designed pri-
marily for on-road use. The AWD feature
gives it some limited off-road capabilities
in situations in which driving surfaces are
relatively level, obstruction-free and other-
wise similar to on-road driving conditions.
Operating it under other than those condi-
tions could subject the vehicle to exces-
sive stress which might result in damage
not eligible for repair under warranty. If
you do take your SUBARU off road, you
should review the common sense precau-
tions in the next section (applicable to the
OUTBACK SPORT) for general guidance.
But please keep in mind that your vehi-
cles off-road capabilities are more limited
than those of the OUTBACK SPORT.
Never attempt to drive through pools and
puddles, or roads flooded with water. Wa-
ter entering the engine air intake or the ex-
haust pipe or water splashing onto electri-
cal parts may damage your vehicle and
may cause it to stall.
OUTBACK SPORT
Your Subaru can be driven on ordinary roads or off-road. But please keep in mind
that an AWD SUBARU is a passenger ve-
hicle and is neither a conventional off-road
vehicle nor an all-terrain vehicle. If you do
take your Subaru off-road, certain com-
mon sense precautions such as the fol-
lowing should be taken:
Make certain that you and all of your
passengers are wearing seatbelts.
Carry some emergency equipment,
such as a towing rope or chain, a shovel,
wheel blocks, first aid kit and cell phone or
citizens band radio.
Drive carefully. Do not take unneces-
sary risks by driving in dangerous areas or
over rough terrain.
Slow down and employ extra caution at
all times. When driving off-road, you will
not have the benefit of marked traffic
lanes, banked curves, traffic signs and the
like.
Do not drive across steep slopes. In-
stead, drive either straight up or straight
down the slopes. A vehicle can much
more easily tip over sideways than it can
end over end. Avoid driving straight up or
down slopes that are too steep.
Avoid sharp turning maneuvers, espe-
cially at higher speeds.
Do not grip the inside or spokes of the
steering wheel. A bad bump could jerk the
wheel and injure your hands. Instead drive
Always maintain a safe driving
speed according to the road and
weather conditions in order to
avoid having an accident on a
sharp turn, during sudden braking
or under other similar conditions.
Always use the utmost care in
driving overconfidence because
you are driving an All-Wheel Drive
vehicle could easily lead to a seri-
ous accident.
Do not drive on rough roads or over
curbs in a vehicle that has 17-inch or
other ultra-low-profile tires. The
wheels and tires could be damaged
by shock forces, leading to abnor-
mal vibration or poor straight-line
tracking. Driving would then be
more difficult.

with your fingers and thumbs on the out-
side of the rim.
If driving through water, such as when
crossing shallow streams, first check the
depth of the water and the bottom of the
stream bed for firmness and ensure that
the bed of the stream is flat. Drive slowly
and completely through the stream. The
water should be shallow enough that it
does not reach the vehicle s undercar-
riage. Water entering the engine air intake
or the exhaust pipe or water splashing
onto electrical parts may damage your ve-
hicle and may cause it to stall. Never at-
tempt to drive through rushing water; re-
gardless of its depth, it can wash away the
ground from under your tires, resulting in
possible loss of traction and even vehicle
rollover.
Always check your brakes for effective-
ness immediately after driving in sand,
mud or water. Do this by driving slowly
and stepping on the brake pedal. Repeat
that process several times to dry out the
brake discs and brake pads.
Do not drive or park over or near flam-
mable materials such as dry grass or fall-
en leaves, as they may burn easily. The
exhaust system is very hot while the en-
gine is running and right after the engine
stops. This could create a fire hazard.
After driving through tall grass, mud, rocks, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stones,
sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from
the underbody. If the vehicle is used with
these materials trapped or adhering to the
underbody, a mechanical breakdown or
fire could occur.
Secure all cargo carried inside the vehi-
cle and make certain that it is not piled
higher than the seatbacks. During sudden
stops or jolts, unsecured cargo could be
thrown around in the vehicle and cause in-
jury. Do not pile heavy loads on the roof.
Those loads raise the vehicle s center of
gravity and make it more prone to tip over.
If you must rock the vehicle to free it
from sand or mud, depress the accelera-
tor pedal slightly and move the selector le-
ver back and forth between D and R re-
peatedly. 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 slip-
pery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT).
Never equip your vehicle with tires larg-
er than those specified in this manual.
Frequent driving of an AWD vehicle un-
der 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 speci-
fied in the maintenance schedule de-
scribed in the
Warranty 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 eligible for war-
ranty coverage.
Wash the vehicle s underbody after off-
road driving. Suspension components are
particularly prone to dirt buildup, so they
need to be washed thoroughly.

8-8 Driving tips
Winter driving
Operation during cold weath-
er
Carry some emergency equipment, such
as tire chains, a window scraper, a bag of
sand, flares, a small shovel, and jumper
cables.
Check the battery and cables. Cold tem-
peratures reduce battery capacity. The
battery must be in good condition to pro-
vide enough power for cold winter starts.
Use an engine oil of proper grade and vis-
cosity 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 afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes be-
cause 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 temper-
ature varies according to how much it is di-
luted, as indicated in the following table.
In order to prevent freezing of washer flu-
id, check the freezing temperatures in the
table above when adjusting the fluid con-
centration 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 fromthe 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 tem-
perature, it may freeze and block the noz-
zles.
Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that
could make the pedals slippery and dan-
gerous.
While warming up the vehicle before driv-
ing, check that the accelerator pedal,
brake pedal, and all other controls operate
smoothly.
Clear away ice and snow that has accu-
mulated under the fenders to avoid mak-
ing steering difficult. During severe winter
driving, stop when and where it is safe to

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.

do so and check under the fenders period-
ically.
Parking in cold weather
Do not use the parking brake when park-
ing for long periods in cold weather since
it could freeze in that position. Instead, ob-
serve 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 af-
ter 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.
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 weath-
er.
Use only additives that are specifically de-
signed for this purpose. When an anti-
freeze 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 en-
gine brake effectively to control the vehi-
cle speed. (Shift into a lower gear when
necessary.)
Avoid shifting down abruptly. Such behav-
ior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) enhanc-
es your vehicle
s braking performance on
snowy and icy roads. Refer to the ABS
(Anti-lock Brake System) section in chap-
ter 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 surfac-
es. Avoid driving on snowy and icy
road surface with summer tires.
225/45R17 tires for WRX-STI
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 engine
running.
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of vehi-
cle control.

8-10 Driving tips
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 com-
pletely 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 wind-
shield despite wiper operation, use the de-
froster with the airflow control dial in
and the temperature control dial
set for maximum warmth. After the wind-
shield 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 vehicle.
NOTE
When the season requiring non-freez-
ing type wiper blades is over, replace
them with standard wiper blades.
Corrosion protection
Refer to the
Corrosion protection section
(chapter 10).
Snow tires
All models except WRX-STIAvoid prolonged continuous driving
in snowstorms. Snow will enter the
engine s intake system and may
hinder the air flow, which could re-
sult in engine shutdown or even
breakdown.
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.
When replacing original tires with
winter (snow) tires, make sure you
use only the same size, construc-
tion and load range as the original
tires listed on the tire placard. Us-
ing other sizes and construction
may affect speedometer/odome-
ter calibration and clearance be-
tween 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, 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 speed-
ometer/odometer calibration. It
also may be dangerous and lead
to loss of vehicle control.

Your vehicle is equipped with
all season
tires as original equipment, which are de-
signed 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 han-
dling characteristics. When you choose a
tire, make sure that there is enough clear-
ance between the tire and vehicle body.
Remember to drive with care at all times
regardless of the type of tires on your ve-
hicle.
WRX-STIYour vehicle is equipped with summer
tires as original equipment, which are in-
adequate 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.

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

pension.
When driving with tire chains, drive at
speeds below 19 mph (30 km/h).
When a temporary spare tire is on a front
wheel, replace 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 be-
cause you are driving with tire chains
could easily lead to a serious accident.
Rocking the vehicle
If you must rock the vehicle to free it from
snow, sand, or mud, depress the acceler-
ator 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 slip-
pery, you can obtain better traction by
starting the vehicle with the transmission

Refer to the
Automatic transmission sec-
tion in chapter 7 for information on holding
the transmission in 2nd position.
Loading your vehicle
Tire chains cannot be used on tires
listed in the following because of
lack of clearance between the tires
and vehicle body.

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 car-
go higher than the top of the seat-
back because it could tumble for-
ward and injure passengers in the
event of a sudden stop or acci-
dent. Keep luggage or cargo low,
as close to the floor as possible.

NOTE
For better fuel economy, do not carry
unneeded cargo.
Vehicle capacity weight
The load capacity of your vehicle is deter-
mined by weight, not by available cargo
space. The maximum load you can carry
in your vehicle is shown on the vehicle
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-
cles 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 han-
dles. 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 luggage
cover (for wagon). Such items
could tumble forward in the event
of a sudden stop or a collision.
This could cause serious injury.
Do not carry spray cans, containers
with flammable or corrosive liquids
or any other dangerous items inside
the vehicle.
