conditions than a two wheel drive vehicle.
There is little difference in handling,
however, during extremely sharp turns or
sudden braking. Therefore, when driving
down a slope or turning corners, be sure
to reduce your speed and maintain an
ample distance from other vehicles.
.Always check the cold tire pressure
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, which is located on the door
pillar on the driver’s side.
.There are some precautions that you
must observe when towing your vehicle.

F9-13.Off road driving
WARNING
.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 brak-
ing or under other similar condi-
tions.
.Always use the utmost care in
driving–overconfidence be-
cause you are driving an All-
Wheel Drive vehicle could easily
lead to a serious accident.
&Legacy
Your AWD vehicle is neither a conven-
tional off-road vehicle nor an all terrain
vehicle. It is a passenger car designed
primarily for on-road use. The AWD
feature gives it some limited off-road
capabilities in situations in which the
driving surface is relatively level, obstruc-
tion-free and otherwise similar to on-road
driving conditions. Operating it under other
than those conditions could subject the
vehicle to excessive stress which might
result in damage not eligible for repairunder warranty. If you do take your
SUBARU off road, you should review the
common sense precautions in the next
section (applicable to the Outback) for
general guidance. But please keep in
mind that your vehicle’s off-road capabil-
ities are more limited than those of the
Outback.
Never attempt to drive through pools and
puddles, or roads flooded with water.
Water entering the engine air intake or
the exhaust pipe or water splashing onto
electrical parts may damage your vehicle
and may cause it to stall.
&Outback
CAUTION
Frequent driving of an AWD model
under hard-driving conditions such
as rough roads or off roads will
necessitate more frequent replace-
ment of the following items than that
specified in the maintenance sche-
dule described in the“Warranty and
Maintenance Booklet”.
.Engine oil
.Brake fluid
.Manual transmission oil (MT
models)
8-6

.Continuously variable transmis-
sion fluid (CVT models)
.Front differential gear oil (CVT
models)
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.
Because of the AWD feature and higher
ground clearance, you can drive your
SUBARU on ordinary roads or off-road.
But please keep in mind that an AWD
SUBARU is a passenger car and is
neither a conventional off-road vehicle
nor an all-terrain vehicle. If you do take
your SUBARU off-road, certain common
sense precautions such as those in the
following list should be taken.
!Before driving
.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.
.Secure all cargo carried inside the
vehicle and make certain that it is not
piled higher than the seatbacks. Duringsudden stops or jolts, unsecured cargo
could be thrown around in the vehicle and
cause injury. 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.
.Never equip your vehicle with tires
larger than those specified in this manual.
!During driving
General precautions:
.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.
Instead, 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 with your fingers and thumbs on
the outside of the rim..Do not drive or park over or near
flammable materials such as dry grass or
fallen leaves, as they may burn easily. The
exhaust system is very hot while the
engine is running and right after the
engine stops. This could create a fire
hazard.
Precautions when driving under espe-
cially dangerous situations:
.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
vehicle and may cause it to stall. Never
attempt to drive through rushing water;
regardless of its depth, it can wash away
the ground from under your tires, resulting
in possible loss of traction and even
vehicle rollover.
.If you must rock the vehicle to free it
from sand or mud, depress the accelerator
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,
Driving tips/Off road driving
–CONTINUED–8-7

Driving tips/Winter driving
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 CVT). For
CVT models, refer to“Selection of manual
mode”F7-29.
!After driving
.Always check your brakes for effec-
tiveness 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.
.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.
.Wash the vehicle’s underbody after off-
road driving. Suspension components are
particularly prone to dirt buildup, so they
need to be washed thoroughly.Winter driving
&Operation during cold
weather
Carry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small 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.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a proper grade and viscosity
for cold weather. Using heavy summer oil
will make it harder to start the engine.
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 following
table.
Washer Fluid Con-
centrationFreezing Temperature
30% 10.48F(−128C)
50%−48F(−208C)
100%−498F(−458C)
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 the
nozzles.
CAUTION
.Adjust the washer fluid concen-
tration appropriately for the out-

In case of emergency/Flat tires
14. Put on the spare tire. Replace the
wheel nuts. Tighten them by hand.
WARNING
Do not use oil or grease on the
wheel studs or nuts when the spare
tire is installed. This could cause the
nuts to become loose and lead to an
accident.
15. Turn the jack handle counterclockwise
to lower the vehicle.
16. Use the wheel nut wrench to securely
tighten the wheel nuts to the specified
torque, following the tightening order in the
illustration.
For the wheel nut tightening torque, refer
to“Tires”F12-9. Never use your foot onthe wheel nut wrench or a pipe extension
on the wrench because you may exceed
the specified torque. Have the wheel nut
torque checked at the nearest automotive
service facility.
17. Store the flat tire. For details, refer to
“Storing a flat tire”F9-8. Also store the
jack and jack handle in their storage
locations.
WARNING
Never place a tire or tire changing
tools in the passenger compartment
after changing wheels. In a sudden
stop or collision, loose equipment
could strike occupants and cause
injury. Store the tire and all tools in
the proper place.
&Storing a flat tire
!Storing in the spare tire compart-
ment (Legacy)
Store the flat tire in the spare tire
compartment. Put the spacer and tighten
the attaching bolt firmly.

Engine overheating
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has fully cooled down.
When the engine is hot, the coolant
is under pressure. Removing the
cap while the engine is still hot
could release a spray of boiling hot
coolant, which could burn you very
seriously.
If the engine overheats, pull off the road
safely and stop the vehicle in a safe place.
&If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down.
&If no steam is coming from
the engine compartment
NOTE
For details about how to check the
coolant level or how to add coolant,
refer to“Engine coolant”F11-14.
1. Keep the engine running at idling
speed.2. Open the hood to ventilate the engine
compartment. Refer to“Engine hood”
F11-7.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the temperature gauge stays in the
overheated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reserve
tank.
If the coolant level is below the“LOW”
mark, add coolant up to the“FULL”mark.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank.
Then remove the radiator cap and fill the
radiator with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.
Towing
WARNING
Never tow AWD vehicles with the
front wheels raised off the ground
while the rear wheels are on the
ground, or with the rear wheels
raised off the ground while the front
wheels are on the ground. This will
cause the vehicle to spin away due
to the operation or deterioration of
the center differential.
If towing is necessary, SUBARU recom-
mends it be done by your SUBARU dealer
or a commercial towing service.

Maintenance and service/Maintenance precautions
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.
.Do not tamper with the wiring of
the SRS airbag system or seat-
belt pretensioner system, or at-
tempt to take its connectors
apart, as that may activate the
system or it can render it inop-
erative. NEVER use a circuit
tester for these wiring. If your
SRS airbag or seatbelt preten-
sioner needs service, consult
your nearest SUBARU dealer.
NOTE
SUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against
performing these services on a
SUBARU vehicle. Non-SUBARU ap-
proved flushing systems use chemi-
cals and/or solvents which have not
been tested or approved by SUBARU.
SUBARU warranties do not cover any
part of the vehicle which is damaged by
adding or applying chemicals and/or
solvents other than those approved or
recommended by SUBARU.
&Before checking or servicing
in the engine compartment
WARNING
.Always stop the engine and apply
the parking brake to prevent the
vehicle from moving.
.Always let the engine cool down.
Engine parts become very hot
when the engine is running and
remain hot for some time after
the engine is stopped.
.Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
.When the ignition switch is in the
“ON”position, the cooling fan
may operate suddenly even
