7-30Starting and operating
When the vehicle is facing uphill, the front
wheels should be turned away from thecurb.
When the vehicle is facing downhill, the
front wheels should be turned into thecurb.
WARNING
. Never leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to people.
. Do not park the vehicle over
flammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
. Be sure to stop the engine if you
take a nap in the vehicle. If
engine exhaust gas enters the
passenger compartment, occu-
pants in the vehicle could die
from carbon monoxide (CO) con-
tained in the exhaust gas.
CAUTION
. Always set the parking brake
firmly when parking your vehicle.
Never rely on the transmission alone to hold the vehicle.
. If your vehicle has a front under-
spoiler and rear underspoiler (if
equipped), pay attention to
blocks and other obstructions
on the ground when parking.
The underspoilers could be da-
maged by contact with them.

8-2Driving tips
New vehicle break-in driving –the first 1,000 miles (1,600
km)
The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km): . Do not race the engine. And do not
allow engine speed to exceed 4,000 rpm
except in an emergency. . Do not drive at one constant engine or
vehicle speed for a long time, either fast or
slow. . Avoid starting suddenly and rapid
acceleration, except in an emergency.. Avoid hard braking, except in an
emergency.
The same break-in procedures should be
applied to an overhauled engine, newly
mounted engine or when brake pads or
brake linings are replaced with new ones. Fuel economy hints
The following suggestions will help to save fuel. .
Select the proper gear position for the
speed and road conditions.. Avoid sudden acceleration or decelera-
tion. Always accelerate gently until you
reach the desired speed. Then try to
maintain that speed for as long aspossible. . Do not pump the accelerator and avoid
racing the engine.. Avoid unnecessary engine idling.
. Keep the engine properly tuned.
. Keep the tires inflated to the correct
pressure shown on the tire placard, which
is located under the door latch on thedriver ’s side. Low pressure will increase
tire wear and fuel consumption. . Use the air conditioner only when
necessary.. Keep the front and rear wheels in
proper alignment.. Avoid carrying unnecessary luggage or
cargo. 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 rear gate closed while
driving to prevent exhaust gas
from entering the vehicle.
NOTE
Due to the expansion and contraction
of the metals used in the exhaust
system, you may hear a crackling
sound coming from the exhaust sys-
tem for a short time after the engine
has been shut off. This sound isnormal. Catalytic converter
Turbo models
Non-turbo models
The catalytic converter is installed in the
exhaust system. It serves as a 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 fuel. Even a small
amount of leaded fuel 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. . Do not drive with an extremely low fuel
level.
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 Driving tips

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. 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. Driving in foreign countries
When planning to use your vehicle in
another country: .
Confirm the availability of the correct
fuel. Refer to “Fuel requirements ”F 7-2.
. Comply with all regulations and re-
quirements of each country.

Driving tips for AWD models
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 model could easily
lead to a serious accident.
. When replacing a tire, you must
use a tire that is of the same size,
circumference, construction,
brand (tread pattern), speed sym-
bol and load index as the original
tires listed on the tire placard.
Using tires of other sizes, cir-
cumferences or constructions
may result in severe mechanical
damage to the drive train of your
vehicle and may affect ride,
handling, braking, speedometer/
odometer calibration, and clear-
ance between the body and tires.
It also may be dangerous and lead to loss of vehicle control.
. You must install four tires that are
of the same size, circumference,
construction, manufacturer,
brand (tread pattern), degree of
wear, speed symbol and load
index. Mixing tires of other sizes,
circumferences or constructions
may result in severe mechanical
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.
CAUTION
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.
All-Wheel Drive distributes the engine
power to all four wheels. AWD models
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 duringdeceleration.
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
following tips in mind: . An AWD model is better able to climb
steeper roads under snowy or slippery Driving tips

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 under the
door latch on the driver ’s side.
. Frequent driving of an AWD vehicle in
hard driving conditions such as steep hills
or dusty roads will necessitate more
frequent replacement of engine oil, brake
fluid and transmission oil than that speci-
fied in the “Warranty and Maintenance
Booklet ”.
. There are some precautions that you
must observe when towing your vehicle.
For detail information, refer to “Towing ”
F 9-14. On-road and off-road driving
WARNING
. In a rollover crash, an unbelted
person is significantly more
likely to die than a person wear-
ing a seat belt. You the driver and
all your passengers should fas-
ten the seatbelts before starting
to drive in order to minimize the
chance of serious injury or death.
. Do not make sharp turns and
quick maneuvers unless abso-
lutely unavoidable. Such actions
are dangerous as you may lose
control, possibly resulting in a
rollover which could cause death
or serious injury.
. 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.
. Whenever strong crosswinds are
present, slow down sufficiently
to maintain control of your vehi-
cle. Remember that your vehicle,
with its higher profile and center of gravity, is more likely to be
affected by crosswinds than or-
dinary passenger cars.
. Always use the utmost care in
driving –overconfidence be-
cause you are driving an All-
Wheel Drive model could easily
lead to a serious accident.
Your vehicle is classified as a utility
vehicle. Utility vehicles feature a higher
ground clearance which enables them to
be used for wide applications including off-
road driving. But please keep in mind that
your vehicle is neither a conventional off-
road vehicle nor an all-terrain vehicle. A
higher center of gravity in relation to the
tread width as compared with ordinary
passenger cars makes vehicles of this
type more likely to roll over. In reality, utility
vehicles have a significantly higher roll-
over rate than other types of vehicles. The
high ground clearance of this vehicle is a
real advantage, giving you a better view of
the road and allowing you to anticipate
problems earlier. However, remember that
your utility vehicle is not designed for high-
speed cornering comparable to ordinary
passenger cars and that your vehicle
could roll over if you make a sharp turn
at high speed.
If you take your SUBARU off-road, certain

common sense precautions such as those
in the following list 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 cross the stream without stopping.
The water should be shallow enough that
it does not reach the vehicle
’s under-
carriage. Water entering the engine air
intake or the exhaust pipe or water
splashing onto electrical parts may da-
mage 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 shift lever/
select lever back and forth between “1 ”/
“ 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. For AT models, refer to“ Selection of manual mode ”F 7-19.
. 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. Driving tips

8-8Driving tips
.Frequent driving of an AWD model
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 ”.
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 warranty coverage. 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 winterstarts.
It normally takes longer to start the engine
in very cold weather conditions. Use an
engine oil of a suitable 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 washer tank with a fluid with a
different concentration from the one used
