Engine exhaust gas (Carbon monoxide)
WARNING
. Never inhale engine exhaust gas.
Engine exhaust gas contains
carbon monoxide, a colorless
and odorless gas which is dan-
gerous, or even lethal, if inhaled.
. Always properly maintain the en-
gine exhaust system to prevent
engine exhaust gas from enter-
ing the vehicle.
. Never run the engine in a closed
space, such as a garage, except
for the brief time needed to drive
the vehicle in or out of it.
. Avoid remaining in a parked
vehicle for a lengthy time while
the engine is running. If that is
unavoidable, then use the venti-
lation fan to force fresh air into
the vehicle.
. Always keep the front ventilator
inlet grille free from snow, leaves
or other obstructions to ensure
that the ventilation system al-
ways works properly.
. If at any time you suspect that exhaust fumes are entering the
vehicle, have the problem
checked and corrected as soon
as possible. If you must drive
under these conditions, drive
only with all windows fully open.
. Keep the trunk lid (Sedan) or rear
gate (Station wagon) closed
while driving to prevent exhaust
gas from entering the vehicle.
NOTE
Due to the expansion and contraction
of the metals used in the manufacture
of the exhaust system, you may hear a
crackling sound coming from the ex-
haust system for a short time after the
engine has been shut off. This sound isnormal. Catalytic converter
WARNING
. Avoid fire hazards. Do not drive
or park the vehicle anywhere
near flammable materials (e.g.
grass, paper, rags or leaves),
because the catalytic converter
operates at very high tempera-tures.
. Keep everyone and flammable
materials away from the exhaust
pipe while the engine is running.
The exhaust gas is very hot.

The catalytic converter is installed in the
exhaust system. It serves as catalyst to
reduce HC, CO and NOx in exhaust
gases, thus providing cleaner exhaust. To avoid damage to the catalytic conver-ter: .
Use only unleaded gasoline. Even a
small amount of leaded gasoline will
damage the catalytic converter. . Never start the engine by pushing or
pulling the vehicle.. Avoid racing the engine.
. Never turn off the ignition switch while
the vehicle is moving.. Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer. . Do not apply undercoating or rust
prevention treatment to the heat shield of
catalytic converter and the exhaust sys-tem. Periodic inspections
To keep your vehicle in the best condition
at all times, always have the recom-
mended maintenance services listed in
the maintenance schedule in the
“War-
ranty and Maintenance Booklet ”per-
formed at the specified time or mileageintervals.

vehicle and may affect ride, handling,
braking, speedometer/odometer calibra-
tion, and clearance between the body
and tires. It also may be dangerous and
lead to loss of vehicle control. .If you use a temporary spare tire to
replace 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
before starting to drive. The recom-
mended tire pressure is provided on the
tire placard, 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, refer to the “Towing ”
section in chapter 9. 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.
& All AWD models except OUTBACK
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 driving
surfaces a relatively level, obstruction-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 repair under
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 capabilities 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
Because of the AWD feature and higher
ground clearance, your SUBARU can be
driven 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 the following
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.
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 ”.

not using common sense precautions
such as those listed above is not eligible
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, 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
thepipingistoolowfortheoutside
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
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.
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. !
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
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

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.

CAUTION
Never use any temporary spare tire
other than the original. Using other
sizes may result in severe mechan-
ical damage to the drive train of yourvehicle.
The temporary spare tire is smaller and
lighter than a conventional tire and is
designed for emergency use only. Re-
move the temporary spare tire and re-
install the conventional tire as soon as
possible because the spare tire is de-
signed only for temporary use.
Check the inflation pressure of the tem-
porary spare tire periodically to keep the
tire ready for use. The correct pressure is
60 psi (420 kPa, 4.2 kgf/cm
2) .
When using the temporary spare tire, note
the following. . Do not exceed 50 mph (80 km/h).
. Do not put a tire chain on the temporary
spare tire. Because of the smaller tire size,
a tire chain will not fit properly. . Do not use two or more temporary
spare tires at the same time.. Do not drive over obstacles. This tire
has a smaller diameter, so road clearance
is reduced.
1) Tread wear indicator bar
2) Indicator location mark
. When the wear indicator appears on
the tread, replace the tire. . The temporary spare tire must be used
only on a rear wheel. If a front wheel tire
gets punctured, replace the wheel with a
rear wheel and install the temporary spare
tire in place of the removed rear wheel.NOTE
If your vehicle is an AWD type with an
automatic transmission but is neither a
Turbo model nor a 3.0-liter model,
deactivate its All-Wheel-Drive capabil-
ity as follows: Before driving your
vehicle with the temporary spare tire,
putasparefuseinsidetheFWD
connector located in the engine com-
partment and confirm that the “
”
warning light comes on. The All-Wheel-
Drive capability of the vehicle has now
been deactivated. After re-installing the
conventional tire, remove the spare
fuse from the FWD connector in order
to reactivate All-Wheel Drive. In case of emergency

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

WARNING
Use the rear tie-down hooks only for
downward anchoring. If they are
used to anchor the vehicle in any
other direction, cables may slip off
the hooks, possibly causing a dan-
gerous situation.
& Using a flat-bed truck
This is the best way to transport your
vehicle. Use the following procedures to
ensure safe transportation.
1. Shift the selector lever into the “P ”
position for automatic transmission vehi-
cles or “1st ”for manual transmission
vehicles.
2. Pull up the parking brake lever firmly. 3. Secure the vehicle onto the carrier
properly with safety chains. Each safety
chain should be equally tightened and
care must be taken not to pull the chains
so tightly that the suspension bottoms out. &
Towing with all wheels on the ground
WARNING
. Never turn the ignition switch to
the “LOCK ”position while the
vehicle is being towed because
the steering wheel and the direc-
tion of the wheels will be locked.
. Remember that the brake booster
and power steering do not func-
tion when the engine is not running. Because the engine is
turned off, it will take greater
effort to operate the brake pedal
and steering wheel.
CAUTION
. If transmission failure occurs,
transport your vehicle on a flat-
bed truck.
. Do not run the engine while being
towed using this method. Trans-
mission damage could result if
the vehicle is towed with the
engine running.
. For vehicles with automatic
transmission, the traveling speed
must be limited to less than 20
mph (30 km/h) and the traveling
distance to less than 31 miles (50
km). For greater speeds and
distances, transport your vehicle
on a flat-bed truck.
1. Check the transmission and differen-
tial oil levels and add oil to bring it to the
upper level if necessary.
2. Release the parking brake and put the
transmission in neutral.
3. The ignition switch should be in the “ Acc ”position while the vehicle is being In case of emergency
