3-16 Instruments and controls
CHECK ENGINE warn-
ing light/Malfunction in-
dicator lamp
If this light comes on steadily or blinks
while the engine is running, it may indicate
that there is a problem or potential prob-
lem somewhere in the emission control
system.
If the light comes on steadily:
If the light comes on steadily while driving
or does not go out after the engine starts,
an emission control system malfunction
has been detected.
You should have your vehicle checked by
an authorized SUBARU dealer immedi-
ately.
NOTE
This light also comes on when the fuel
filler cap is not tightened until it clicks.
If you have recently refueled your vehicle,
the cause of the CHECK ENGINE warning
light/malfunction indicator lamp coming on
could be a loose or missing fuel filler cap.
Remove the cap and retighten it until it
clicks. Make sure nothing is interfering
with the sealing of the cap. Tightening the
cap will not make the CHECK ENGINE
warning light turn off immediately. It may
take several driving trips. If the light does
not go out, take your vehicle to your au-
thorized SUBARU dealer immediately.
If the light is blinking:
If the light is blinking while driving, an en-
gine misfire condition has been detected
which may damage the emission control
system.
To prevent serious damage to the emis-
sion control system, you should do the fol-
lowing.
Reduce vehicle speed.
Avoid hard acceleration.
Avoid steep uphill grades.
Reduce the amount of cargo, if possi-
ble.
Stop towing a trailer as soon as pos-
sible. The CHECK ENGINE warning light may
stop blinking and come on steadily after
several driving trips. You should have
your vehicle checked by an authorized
SUBARU dealer immediately.
Charge warning light
If this light comes on when the engine is
running, it may indicate that the charging
system is not working properly.
If the light comes on while driving or does
not go out after the engine starts, stop the
engine at the first safe opportunity and
check the alternator belt. If the belt is
loose, broken or if the belt is in good con-
dition but the light remains on, contact
your nearest SUBARU dealer immediate-
ly.

light
If this light comes on when the engine is
running, it may indicate that the engine oil
pressure is low and the lubricating system
is not working properly.
If the light comes on while driving or does
not go out after the engine starts, stop the
engine at the first safe opportunity and
check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil
If the CHECK ENGINE light comes
on while you are driving, have your
vehicle checked/repaired by your
SUBARU dealer as soon as possi-
ble. Continued vehicle operation
without having the emission control
system checked and repaired as
necessary could cause serious
damage, which may not be covered
by your vehicle

1. To open the fuel filler lid, pull the lid re-
lease lever up. The lever is on the floor at
the left of the driver ’s seat.
1) Open
2) Close
2. Remove the fuel filler cap by turning it
slowly counterclockwise.
3. Stop filling the tank after the fuel filler
pump automatically stops. Do not add any
more fuel.
4. 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.
5. Close the fuel filler lid completely.
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 “ ” or “FUEL
DOOR ” 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 may come on. Refer to
the “Warning and indicator lights ” sec-
tion located in chapter 3.
(Turbo model only) Promptly put fuel in
the tank whenever the low fuel warning

light comes on. Engine misfires as a re-
sult of an empty tank could cause dam-
age to the engine.
State emission testing (U.S.
only)
At state inspection time, remember to
tell your inspection or service station
in advance not to place your Subaru
AWD vehicle on a two-wheel dyna-
mometer. Otherwise, serious transmis-
sion damage will result.
Some states have started using dyna-
mometers in their state inspection pro-
grams in order to meet their obligation un-
der federal law to implement stricter vehi-
cle emission standards to reduce air pollu-
tion from vehicles. A dynamometer is a
treadmill or roller-like testing device that
allows your vehicle
’s wheels to turn while
the vehicle remains in one place. Depend-
ing on the severity of a state ’s air pollution
problems, the states must adopt either a“ basic ” or “enhanced ” vehicle emission in-
spection test. Normally, a portion of the
basic emission test consists of an emis-
sion inspector inserting an analyzer probe
into the exhaust pipe of an idling vehicle
for a short period of time. States with more
severe air pollution problems are required
to adopt an enhanced vehicle emission
test. This test simulates actual driving
conditions on a dynamometer and permits
more accurate measurement of tailpipe emitted pollution than the basic emission
test.
The U.S. Environmental Protection Agen-
cy (EPA) and states using two-wheel dy-
namometers in their emission testing pro-
grams have
EXEMPTED Subaru AWD
vehicles from the portion of the testing
program that involves a two-wheel dyna-
mometer.
There are some states that use four-wheel
dynamometers in their testing programs.
When properly used, that equipment will
not damage an AWD Subaru vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
Never add any cleaning agents to
the fuel tank. The addition of a
cleaning agent may cause dam-
age to the fuel system.
Make sure that the cap is tight-
ened until it clicks to prevent fuel
spillage in the event of an acci-
dent.
Do not let fuel spill on the exterior
surfaces of the vehicle.
Fuels may cause paint damage,
which is not covered under the
SUBARU Limited Warranty.
Always use a genuine SUBARU
fuel filler cap. If you use the wrong
cap, it may not fit or have proper
venting, and your fuel tank and
emission control system might be
damaged.
Testing of an All-Wheel Drive vehi-
cle must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in un-
controlled vehicle movement and
may cause an accident or injuries to
persons nearby.

do so and check under the fenders period-
ically.
Parking in cold weather
Do not use the parking brake when park-
ing for long periods in cold weather since
it could freeze in that position. Instead, ob-
serve 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 af-
ter 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 weath-
er.
Use only additives that are specifically de-
signed for this purpose. When an anti-
freeze 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
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 en-
gine brake effectively to control the vehi-
cle speed. (Shift into a lower gear when
necessary.)
Avoid shifting down abruptly. Such behav-
ior can cause the wheels to lock, possibly
leading to loss of vehicle control.
An anti-lock brake system (ABS) enhanc-
es your vehicle
’s braking performance on
snowy and icy roads. Refer to the “ABS
(Anti-lock Brake System) ” section in chap-
ter 7 for information on braking on slippery
surfaces.
NOTE
The following tires are summer tires.
Compared with winter and all-season
tires, summer tires give significantly
less grip on snowy and icy road surfac-
es. Avoid driving on snowy and icy
road surface with summer tires.
225/45R17 tires for WRX-STI
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 engine
running.
Do not use the cruise control on
slippery roads such as snowy or icy
roads. This may cause loss of vehi-
cle control.

NOTE
For better fuel economy, do not carry
unneeded cargo.
Vehicle capacity weight
The load capacity of your vehicle is deter-
mined by weight, not by available cargo
space. The maximum load you can carry
in your vehicle is shown on the vehicle
When you carry something inside
the vehicle, secure it whenever
you can to prevent it from being
thrown around inside the vehicle
during sudden stops, sharp turns
or in an accident.
Do not pile heavy loads on the
roof. These loads raise the vehi-
cle’s center of gravity and make it
more prone to tip over.
Secure lengthy items properly to
prevent them from shooting for-
ward and causing serious injury
during a sudden stop.
Never exceed the maximum load
limit. If you do, some parts on
your vehicle can break, or it can
change the way your vehicle han-
dles. This could result in loss of
control and cause personal injury.
Also, overloading can shorten the
life of your vehicle.
Do not place anything on the rear
shelf behind the rear seatback (for
sedan) or the extended luggage
cover (for wagon). Such items
could tumble forward in the event
of a sudden stop or a collision.
This could cause serious injury.
Do not carry spray cans, containers
with flammable or corrosive liquids
or any other dangerous items inside
the vehicle.

Hitch harness connector – Wagon
8. Connect the hitch wire harness ’s black
four-pin wire connector to the towing trail-
er ’s wire harness
9. Confirm proper function of the hitch
wire harness by individually activating the
brake, right turn signal, left turn signal,
stop, and parking lights on the trailer.
NOTE
Always disconnect the trailer wire har-
ness before launching or retrieving a
watercraft.
When you do not tow a trailer
Remove the ball mount from the hitch
receiver tube and insert the receiver cover
onto the hitch receiver tube.
Place the dust cap over the four-pin
connector of the hitch wire harness to pro-
tect against possible damage.
Occasionally lubricate terminals of the
four-pin connector using terminal grease.
Trailer towing
Your vehicle is designed and intended to
be used primarily as a passenger-carrying
vehicle. Towing a trailer puts additional
loads on your vehicle ’s engine, drivetrain,
brakes, tires and suspension and has an
adverse effect on fuel economy.
If you do decide to tow a trailer, your safe-
ty and satisfaction depend upon proper
use of correct equipment and cautious op-
eration of your vehicle. Seek the advice of
your SUBARU dealer to assist you in pur-
chasing a hitch and other necessary tow-
ing equipment appropriate for your vehi-
cle. In addition, be sure to follow the in-
structions on correct installation and use
provided by the trailer and other towing
equipment manufacturers.
SUBARU assumes no responsibility for in-
juries or vehicle damage that result from
trailer towing equipment, or from any er-
rors or omissions in the instructions ac-
companying such equipment or for your
failure to follow the proper instructions.
Warranties and maintenance
SUBARU warranties do not apply to vehi-
cle damage or malfunction caused by trail-
er towing. If you use your vehicle to tow a
trailer, more frequent maintenance will be

11-8 Maintenance and service
Engine oil
Checking the oil level
Check the engine oil level at each fuel
stop.
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the dipstick, wipe it clean, and
insert it again.
3. Be sure the dipstick is correctly insert-
ed until it stops with the graphic
symbol on its top appearing as
shown in the illustration.
1) Notch
2) Upper level
3) Lower level
4. Pull out the dipstick again and check
the oil level on it. If it is below the lower
level, add oil to bring the level up to the up-
per level.
If you check the oil level just after stopping
the engine, wait a few minutes for the oil to
drain back into the oil pan before checking
the level.
Just after driving or while the engine is
warm, the engine oil level reading may be
in a range between the upper level and
the notch mark. This is caused by thermal
expansion of the engine oil.
To prevent overfilling the engine oil, do not
add any additional oil above the upper lev-
el when the engine is cold.
Changing the oil and oil filter
Change the oil and oil filter according to
the maintenance schedule in the “Warran-
ty and Maintenance Booklet ”.
The engine oil and oil filter must be
changed more frequently than listed in the
maintenance schedule when driving on
dusty roads, when short trips are frequent-
ly made, or when driving in extremely cold
whether.
1. Warm up the engine by letting the en-
gine idle for approximately 10 minutes to
ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine.
3. Remove the oil filler cap.
B00467
Use only engine oil with the rec-
ommended grade and viscosity.
Be careful not to spill engine oil
when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If en-
gine oil gets on the exhaust pipe,
be sure to wipe it off.
