2012 SUBARU IMPREZA WRX oil change

CAUTION
. Do not allow the retractor to roll
up the seatbelt too quickly.
Otherwise, the metal tongue
plates may hit against the trim,
resulting in damaged trim.
. Have the seatbelt fully rolled up
so that the tongue plates are
neatly stored. A hanging tongue
plate can swing and hit against
the trim during driving, causing
damage to the trim. &
Seatbelt maintenance
To clean the seatbelts, use a mild soap
and lukewarm water. Never bleach or dye
the belts because this could seriously
affect their strength.
Inspect the seatbelts and attachments
including the webbing and all hardware
periodically for cracks, cuts, gashes,
tears, damage, loose bolts or worn areas.
Replace the seatbelts even if only minor
damage is found.
CAUTION
. Keep the belts free of polishes,
oils, chemicals and particularly
battery acid.
. Never attempt to make modifica-
tions or changes that will prevent
the seatbelt from operating prop-
erly. Front seatbelt pretensioners
The driver
’s and front passenger ’s seat-
belts have a seatbelt pretensioner. The
seatbelt pretensioners are designed to be
activated in the event of an accident
involving a moderate to severe frontalcollision.
The pretensioner sensor also serves as
the frontal SRS airbag sensor. If the
sensor detects a certain predetermined
amount of force during a frontal collision,
the front seatbelt is quickly drawn back in
by the retractor to take up the slack so that
the belt more effectively restrains the front
seat occupant.
When a seatbelt pretensioner is activated,
an operating noise will be heard and a Seat, seatbelt and SRS airbags

11-8Maintenance and service
Engine oil NOTE .The engine oil consumption rate is
not stabilized, and therefore cannot be
determined until the vehicle has tra-
veled at least several thousand miles
(kilometers). Even after break-in, when
the vehicle is used under severe driv-
ing conditions such as those men-
tionedintheWarrantyandMainte-
nance Booklet, engine oil is consumed
or deteriorated more quickly than un-
der normal driving conditions. If you
drive your vehicle under these severe
conditions, you should check the oil
level at least at every second fuel fill-up
time, and change the oil more fre-
quently. Please refer to the Warranty
and Maintenance Booklet for more de-tails.. If the oil consumption rate seems
abnormally high after the break-in
period, for example more than 1 quart
per 1,200 miles or 1 liter per 2,000
kilometers, contact your SUBARU deal-
er. &
Checking the oil level
Check the engine oil level at each fuelstop.
1. Park the vehicle on a level surface and
stop the engine.
2. Pull out the level gauge that has the “” symbol on top, wipe it clean, and
insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.
1) Notch
2) Upper level
3) Lower level
4. Pull out the level gauge again and
check the oil level on it. If it is below the
lower level, add oil to bring the level up to
the upper level.
CAUTION
. Use only engine oil with the
recommended grade and vis-
cosity.
. 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
engine oil gets on the exhaust

pipe, be sure to wipe it off.
. If the level gauge is not pulled out
easily, twist the level gauge right
and left, then pull it out. Other-
wise, you may be injured acci-
dentally straining yourself.
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
level when the engine is cold. & Changing the oil and oil filter
CAUTION
. If you change your own oil, be
sure to drain all the oil from the
filter before disposal.
. Do not dispose of used engine oil
by placing it in the trash, or by
pouring it onto the ground, into
sewers, or into any body of water.
Check with your local govern- ment office for the proper dis-
posal options available to you.
Change the oil and oil filter according to
the maintenance schedule in the “War-
ranty 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
frequently made, or when driving in
extremely cold weather.
1. Warm up the engine by letting the
engine 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.
4. Drain out the engine oil by removing
the drain plug while the engine is still
warm. The used oil should be drained into
an appropriate container and disposed of
properly.
WARNING
Be careful not to burn yourself with
hot engine oil.
5. Wipe the seating surface of the drain
plug with a clean cloth and tighten it
securely with a new sealing washer after
the oil has completely drained out.
6. Remove the under cover.
7. Remove the oil filter with an oil filter wrench.
8. Before installing a new oil filter, apply a Maintenance and service

mended engine oil for optimum engine
performance. Conventional oil may be
used if synthetic oil is unavailable.Cooling system
WARNING
Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down
completely. Since the coolant is
under pressure, you may suffer
serious burns from a spray of boil-
ing hot coolant when the cap isremoved.
CAUTION
. Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). This coolant
should not be mixed with any
other brand or type of coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. Should it be
necessary to top up the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand or
type, the maintenance interval is shortened to that of the mixingcoolant.
. Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
& Cooling fan, hose and con- nections
Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Refer to “Temperature gauge ”
F 3-10.
Check the fuse and replace it if necessary.
Refer to “Fuses ”F 11-37 and “Fuse panel
located in the engine compartment ”F 12-
12.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness. Maintenance and service

Check the coolant level at each fuel stop.
1. Check the coolant level on the outside of the reservoir while the engine is cool.
2. If the level is close to or lower than the “
LOW ”level mark, add coolant up to the
“ FULL ”level mark. If the reserve tank is
empty, remove the radiator cap and refill
as required.
3. After refilling the reserve tank and the
radiator, reinstall the cap and check that
the rubber gaskets inside the radiator cap
are in the proper position.

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 different
types, sizes or degrees of wear
can result in damage to the
vehicle ’s power train. Use of
different types or sizes of tires
can also dangerously reduce
controllability and braking per-
formance and can lead to anaccident.
. Use only radial tires. Do not use
radial tires together with belted
bias tires and/or bias-ply tires.
Doing so can dangerously re-
duce controllability, resulting in
an accident.
& Wheel replacement
When replacing wheels due, for example,
to damage, make sure the replacement
wheels match the specifications of the
wheels that are fitted as standard equip-
ment. Replacement wheels are available from SUBARU dealers.
WARNING
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could
interfere with brake caliper opera-
tion and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of
vehicle control could lead to anaccident.
NOTE
When any of the wheels are removed
and replaced for tire rotation or to
change a flat tire, always check the
tightness of the wheel nuts after driv-
ing approximately 600 miles (1,000 km).
If any nut is loose, tighten it to the
specified torque. Aluminum wheels
Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety. .
When any of the wheels are removed
and replaced for tire rotation or to change
a flat tire, always check the tightness of
the wheel nuts after driving approximately
600 miles (1,000 km). If any nut is loose,
tighten it to the specified torque. . Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the wheel. . Never let the wheel rub against sharp
protrusions or curbs.. When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for aluminum wheels.
