.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. . 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. .
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. . 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 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
vehicle 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 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. . 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 with the transmission
in 2nd than 1st (both for MT and AT). . Never equip your vehicle with tires
larger than those specified in this manual.. Wash the vehicle ’s underbody after off-
road driving. Suspension components are
particularly prone to dirt buildup, so they
need to be washed thoroughly. . 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 “Warranty and Mainte-
nance Booklet ”.

8-10Driving tips
CAUTION
Avoid prolonged continuous driving
in snowstorms. Snow will enter the
engine ’s intake system and may
hinder the air flow, which could
result in engine shutdown or evenbreakdown.
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) ”and
“ Vehicle Dynamics Control system ”sec-
tion in chapter 7 for information on braking
on slippery surfaces. !
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 button/dial in the “
”position and
the temperature control dial set for max-
imum 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 button/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 vehicle.
CAUTION
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.
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).

since this may result in dangerous hand-
ling 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 yourvehicle. &Tire chains
CAUTION
Tire chains cannot be used on any
tires for your Legacy and Outback
because of lack of clearance be-
tween the tires and vehicle body.
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 orsuspension.
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 because
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 accel-
erator 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 –4-
speed ”and “Automatic transmission –5-
speed ”section in chapter 7 for information
on holding the transmission in 2nd posi- tion. Loading your vehicle
WARNING
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.
WARNING
. 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 luggage or cargo
low, as close to the floor as Driving tips

ment and cargo does not exceed
the maximum load limit. Over-
loading may cause damage to
the vehicle and create a safetyhazard.
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). Refer to 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 attachment 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. !
Installing carrying attachments on
the crossbars
When installing any carrying attachment
such as a bike carrier, ski carrier, kayak
carrier, cargo basket, etc. on the cross-
bars, follow the manufacturer ’s instruc-
tions and make sure that the attachment is
securely fixed to the crossbars. Use only
attachments designed specifically for the
crossbars. A set of the crossbars is
designed to carry loads (cargo and attach-
ment) of not more than 100 lbs (45 kg).
Before operating the vehicle, make sure
that the cargo is properly secured on theattachment.
NOTE
Remember that the vehicle ’s center of
gravity is altered 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 increased. ! Removal and installation of the crossbars
The crossbars can be removed when you
do not use the roof to carry cargo. !
To remove the crossbar
1. Loosen and remove the T-30 torx®
head screw from the top of each crossbar
end support.
Loosen the lower clamps.

8-18Driving tips
1) Lower clamp
2) T-30 torx® head screw
5. Tighten the lower clamps onto the
crossbar. Using a torque wrench, loosely
tighten the T-30 torx® head screws. NOTE
It may be necessary to squeeze the
lower clamp and the end support
together to compress the pads and
gain a better alignment of the pieces
while trying to start the screw. Use care
not to crossthread the screw in theinsert.6. Adjust the alignment of the crossbar
on the roof rails, and if available, use a T-
30 torx® bit and torque wrench and tighten
the T-30 torx® head screws to 30 to 35
lbf·in (3.4 to 4.0 N·m, 0.35 to 0.41 kgf·m) of
torque (or tighten securely with the torx®
wrench provided). Rear crossbar:1) Zero gap
Install the rear cross bar so that the rear
edges of both crossbar end supports are
aligned (zero gap) with the front edges of
both rear roof rail supports.
Install the rear crossbar in the same
manner as the front crossbar.
CAUTION
Do not carry cargo on the roof when
the crossbars are removed. Lug-
gage on the roof will be thrown
forward or backward in sudden
stops or rapid accelerations, result-
ing in a dangerous road hazard.

8-28Driving tips
! Before starting out on a trip
. Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If
any problems are apparent, do not tow the
trailer. . Check that the vehicle sits horizontally
with the trailer attached. If the vehicle is
tipped sharply up at the front and down at
the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then
confirm that the load and its distribution
are acceptable. . Check that the tire pressures are
correct.. Check that the vehicle and trailer are
connected properly. Confirm that
–the trailer tongue is connected
properly to the hitch ball. – the trailer lights connector is con-
nected properly and trailer ’s brake
lights illuminate when the vehicle ’s
brake pedal is pressed, and that the trailer ’s turn signal lights flash when
the vehicle ’s turn signal lever is oper-
ated. – the safety chains are connected
properly.– all cargo in the trailer is secured
safety in position.– the side mirrors provide a good
rearward field of view without a sig- nificant blind spot.
. Sufficient time should be taken to learn
the “feel ”of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping and
backing up. ! Driving with a trailer
. You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may
result in skidding or jackknifing and loss ofcontrol. . Avoid abrupt starts and sudden accel-
erations. If your vehicle has a manual
transmission, always start out in first gear
and release the clutch at moderate enginerevolution. . Avoid uneven steering, sharp turns and
rapid lane changes.. Slow down before turning. Make a
longer than normal turning radius because
the trailer wheels will be closer than the
vehicle wheels to the inside of the turn. In
a tight turn, the trailer could hit yourvehicle. . Crosswinds will adversely affect the
handling of your vehicle and trailer, caus-
ing sway. Crosswinds can be due to
weather conditions or the passing of large
trucks or buses. If swaying occurs, firmly
grip the steering wheel and slow down immediately but gradually. .
When passing other vehicles, consid-
erable distance is required because of the
added weight and length caused by
attaching the trailer to your vehicle.
1) Left turn
2) Right turn
. Backing up with a trailer is difficult and
takes practice. When backing up with a
trailer, never accelerate or steer rapidly.
When turning back, grip the bottom of the
steering wheel with one hand and turn it to
the left for a left turn, and turn it to the right
for a right turn. . If the ABS warning light illuminates
while the vehicle is in motion, stop towing
the trailer and have repairs performed
immediately by the nearest SUBARU
dealer.

5. Start the engine of the vehicle with the
booster battery and run it at moderate
speed. Then start the engine of the vehicle
that has the discharged battery.
6. When finished, carefully disconnect
the cables in exactly the reverse order.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
1. Keep the engine running at idling speed.
2. Open the hood to ventilate the engine compartment.
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 at the
overheated zone, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reservetank.
If the coolant level is below the
“MIN ”
mark, add coolant up to the “MAX ”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. In case of emergency

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 left unremoved, the oil could
catch fire.
11. Reinstall the cover under the oil filter.
12. Pour engine oil through the filler neck. Oil capacity (Guideline):
2.5-liter models: 4.2 US qt (4.0 liters, 3.5
Imp qt)
3.0-liter models: 5.8 US qt (5.5 liters, 4.8
Imp qt)
The oil quantity indicated above is only a
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 tempera-
ture 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. &
Recommended grade and viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Oil grade: ILSAC GF-4, which can be identified with
the ILSAC certification mark (Starburst mark)
or API classification SM with the words“ENERGY CONSERVING ”
These recommended oil grades can be
identified by looking for either or both of
the following marks displayed on the oil
container.

may damage the paint surface.
6. Pour the coolant and fill to the reser-
voir tank’s “FULL ”level mark.
7. Put the radiator cap back on and
tighten firmly. At this time, make sure that the rubber gasket in the radiator cap is
correctly in place.
8. Start and run the engine for more than
five minutes at 2,000 to 3,000 rpm.
9. Stop the engine and wait until the
coolant cools down (122 to 140
8F [50 to
60 8C]). If there is any loss of coolant, add
coolant to the radiator ’s filler neck and to
the reserve tank ’s “FULL ”level.
10. Put the radiator cap and reservoir cap
back on and tighten firmly. Air cleaner element
WARNING
Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters
intake air but also stops flames if
the engine backfires. If the air
cleaner element is not installed
when the engine backfires, you
could be burned.
CAUTION
When replacing the air cleaner ele-
ment, use a genuine SUBARU air
cleaner element. If it is not used,
there is the possibility of causing a
negative effect to the engine.
The air cleaner element functions as a
filter screen. When the element is perfo-
rated or removed, engine wear will be
excessive and engine life shortened.
The air cleaner element is a dry type. It is
unnecessary to clean or wash the ele-ment. Maintenance and service

described in the following, have it checked
by your SUBARU dealer.
1. With the engine off, depress the brake
pedal several times, applying the same
pedal force each time. The distance the
pedal travels should not vary.
2. With the brake pedal depressed, start
the engine. The pedal should move
slightly down to the floor.
3. With the brake pedal depressed, stop
the engine and keep the pedal depressed
for 30 seconds. The pedal height should
not change.
4. Start the engine again and run for
approximately one minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake
