.When opening the cap, grasp it
firmly and turn it slowly to the left.
Do not remove the cap quickly.
Fuel may be under pressure and
spray out of the fuel filler neck,
especially in hot weather. If you
hear a hissing sound while you
are removing the cap, wait for the
sound to stop and then slowly
open the cap to prevent fuel from
spraying out and creating a fire
hazard.3. Set the fuel filler cap on the cap holder
inside the fuel filler lid.
WARNING
.When refueling, insert the fuel
nozzle securely into the fuel filler
pipe. If the nozzle is lifted or not
fully inserted, its automatic stop-
ping mechanism may not func-
tion, causing fuel to overflow the
tank and creating a fire hazard.
.Stop refueling when the auto-
matic stop mechanism on the
fuel nozzle activates. If you con-
tinue to add fuel, temperature
changes or other conditions
may cause fuel to overflow from
the tank and create a fire hazard.
4. Stop filling the tank after the fuel filler
pump automatically stops. Do not add any
more fuel.
5. Put the cap back on, turn it clockwise
until you hear a clicking noise. Be certain
not to catch the tether under the cap while
tightening.
CAUTION
Make sure that the cap is tightened
until it clicks to prevent fuel spillage
in the event of an accident.
6. Close the fuel filler lid completely.
CAUTION
If you spill any fuel on the painted
surface, rinse it off immediately.
Otherwise, the painted surface
could be damaged.NOTE.You will see the“
”sign in the fuel
gauge. This indicates that the fuel filler
door (lid) is located on the right side of
the vehicle.
.If the fuel filler cap is not tightened
until it clicks or if the tether is caught
under the cap, the CHECK ENGINE
warning light/malfunction indicator
light may illuminate. Refer to“CHECK
ENGINE warning light/Malfunction in-
dicator light”F3-16.
CAUTION
.Never add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause da-
mage to the fuel system.
.After refueling, turn the cap
clockwise until it clicks to ensure
that it is fully tightened. If the cap
is not securely tightened, fuel
may leak out while the vehicle is

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, either fast or slow.
.Avoid starting suddenly and rapid ac-
celeration, except in an emergency.
.Avoid hard braking, except in an emer-
gency.
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 hintsThe 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 as possi-
ble.
.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 the
driver’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.
.The indication of the ECO gauge shows
a reference for saving fuel. For details,
refer to“ECO gauge”F3-12.
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 entering
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 ve-
hicle for a lengthy time while the
engine is running. If that is un-
avoidable, then use the ventila-
tion 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

Maintenance precautionsWhen maintenance and service are re-
quired, it is recommended that all work be
done by an authorized SUBARU dealer.
If you perform maintenance and service by
yourself, you should familiarize yourself
with the information provided in this sec-
tion on general maintenance and service
for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
WARNING
.Testing of an All-Wheel Drive
model must NEVER be performed
on a single two-wheel dynam-
ometer or similar apparatus. At-
tempting to do so will result in
transmission damage and in un-
controlled vehicle movement and
may cause an accident or injuries
to persons nearby.
.Always select a safe area when
performing maintenance on your
vehicle.
.Always be very careful to avoidinjury when working on the vehi-
cle. Remember that some of the
materials in the vehicle may be
hazardous if improperly used or
handled, for example, battery
acid.
.Your vehicle should only be ser-
viced by persons fully competent
to do so. Serious personal injury
may result to persons not experi-
enced in servicing vehicles.
.Always use the proper tools and
make certain that they are well
maintained.
.Never get under the vehicle sup-
ported only by a jack. Always use
safety stands to support the
vehicle.
.Never keep the engine running in
a poorly ventilated area, such as
a garage or other closed areas.
.Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire.
.Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only
by your SUBARU dealer.
.Wear adequate eye protection to
guard against getting oil or fluids

WARNING
If the low tire pressure warning light
does not illuminate briefly after the
ignition switch is turned ON or the
light illuminates steadily after blink-
ing for approximately one minute,
you should have your Tire Pressure
Monitoring System checked at a
SUBARU dealer as soon as possi-
ble.
If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Other-
wise an accident involving serious
vehicle damage and serious perso-
nal injury could occur.
1) Keep driving straight ahead while
gradually reducing speed.
2) Slowly pull off the road to a safe
place.
If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, refer to“Flat tires”F9-5.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.
&Tire inspectionCheck on a daily basis that the tires are
free from serious damage, nails, and
stones. At the same time, check the tires
for abnormal wear.
Contact your SUBARU dealer immediately
if you find any problem.NOTE.When the wheels and tires strike
curbs or are subjected to harsh treat-
ment as when the vehicle is driven on a
rough surface, they can suffer damage
that cannot be seen with the naked eye.
This type of damage does not become
evident until time has passed. Try not to
drive over curbs, potholes or on other
rough surfaces. If doing so is unavoid-able, keep the vehicle’s speed down to
a walking pace or less, and approach
the curbs as squarely as possible. Also,
make sure the tires are not pressed
against the curb when you park the
vehicle.
.If you feel unusual vibration while
driving or find it difficult to steer the
vehicle in a straight line, one of the tires
and/or wheels may be damaged. Drive
slowly to the nearest authorized
SUBARU dealer and have the vehicle
inspected.
&Tire pressures and wearMaintaining the correct tire pressures
helps to maximize the tires’service lives
and is essential for good running perfor-
mance. Check and, if necessary, adjust
the pressure of each tire (including the
spare) at least once a month (for example,
during a fuel stop) and before any long
journey.

Tire placardCheck the tire pressures when the tires are
cold. Use a pressure gauge to adjust the
tire pressures to the values shown on the
tire placard. The tire placard is located on
the door pillar on the driver’s side.
Driving even a short distance warms up
the tires and increases the tire pressures.
Also, the tire pressures are affected by the
outside temperature. It is best to check tire
pressure outdoors before driving the ve-
hicle.
When a tire becomes warm, the air inside it
expands, causing the tire pressure to
increase. Be careful not to mistakenly
release air from a warm tire to reduce its
pressure.
NOTE.The air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3
kgf/cm
2) when the tire becomes warm.
.The tires are considered cold when
you have parked the vehicle for at least
three hours or have driven less than
one mile (1.6 km).
WARNING
Do not let air out of warm tires to
adjust pressure. Doing so will result
in low tire pressure.
Incorrect tire pressures detract from con-
trollability and ride comfort, and they cause
the tires to wear abnormally..Correct tire pressure(tread worn
evenly)
Roadholding is good, and steering is
responsive. Rolling resistance is low, so
fuel consumption is also lower.

.Under inflated tire(tread worn on
shoulders)Rolling resistance is high, so fuel con-
sumption is also higher..Over inflated tire(tread worn in the
center)
Ride comfort is poor. Also, the tire magni-
fies the effects of road-surface bumps and
dips, possibly resulting in vehicle damage.
If the tire placard shows tire pressures for
the vehicle when fully loaded, adjust the
tire pressures to the values that match the
loading conditions.
WARNING
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly heat up. A sharp increase in
temperature could cause tread se-
paration, and destruction of the
tires. The resulting loss of vehiclecontrol could lead to an accident.
&Wheel balanceEach wheel was correctly balanced when
your vehicle was new, but the wheels will
become unbalanced as the tires become
worn during use. Wheel imbalance causes
the steering wheel to vibrate slightly at
certain vehicle speeds and detracts from
the vehicle’s straight-line stability. It can
also cause steering and suspension sys-
tem problems and abnormal tire wear. If
you suspect that the wheels are not
correctly balanced, have them checked
and adjusted by your SUBARU dealer.
Also have them adjusted after tire repairs
and after tire rotation.
CAUTION
Loss of correct wheel alignment
causes the tires to wear on one side
and reduces the vehicle’s running
stability. Contact your SUBARU
dealer if you notice abnormal tire
wear.

crease in temperature could cause
tread separation, and failure of the
tire(s). Possible resulting loss of
vehicle control could lead to an
accident.!Measuring and adjusting air
pressure to achieve proper in-
flationCheck and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are
cold. Use a pressure gauge to
adjust the tire pressures to the
specific values. Driving even a short
distance warms up the tires and
increases the tire pressures. Also,
the tire pressures are affected by
the outside temperature. It is best to
check tire pressure outdoors before
driving the vehicle. When a tire
becomes warm, the air inside it
expands, causing the tire pressure
to increase. Be careful not to mis-
takenly release air from a warm tire
to reduce its pressure.
