2016 SUBARU WRX light

Cleaning the interior Use a soft, damp cloth to clean the climate
control panel, audio equipment, instru-
ment panel, center console, combination
meter panel, and switches. (Do not use
organic solvents.)
& Seat fabric Remove loose dirt, dust or debris with a
vacuum cleaner. If the dirt is caked on the
fabric or hard to remove with a vacuum
cleaner, use a soft brush then vacuum it.
Wipe the fabric surface with a tightly
wrung cloth and dry the seat fabric
thoroughly. If the fabric is still dirty, wipe
using a solution of mild soap and luke-
warm water then dry thoroughly.
If the stain does not come out, try a
commercially-available fabric cleaner. Use
the cleaner on a hidden place and make
sure it does not affect the fabric adversely.
Use the cleaner according to its instruc-
tions.
CAUTION
When cleaning the seat, do not use
benzine, paint thinner, or any similar
materials. Doing so could damage
the surface and cause the color to deteriorate.
& Leather seat materials The leather used by SUBARU is a high
quality natural product which will retain its
distinctive appearance and feel for many
years with proper care.
Allowing dust or road dirt to build up on the
surface can cause the material to become
brittle and to wear prematurely. Regular
cleaning with a soft, moist, natural fiber
cloth should be performed monthly, taking
care not to soak the leather or allow water
to penetrate the stitched seams.
A mild detergent suitable for cleaning
woolen fabrics may be used to remove
difficult dirt spots, rubbing with a soft, dry
cloth afterwards to restore the luster. If
your SUBARU is to be parked for a long
time in bright sunlight, it is recommended
that the seats and head restraints be
covered, or the windows shaded, to
prevent fading or shrinkage.
Minor surface blemishes or bald patches
may be treated with a commercial leather
spray lacquer. You will discover that each
leather seat section will develop soft folds
or wrinkles, which is characteristic of
genuine leather. & Synthetic leather upholstery The synthetic leather material used on the
SUBARU may be cleaned using mild soap
or detergent and water, after first vacuum-
ing or brushing away loose dirt. Allow the
soap to soak in for a few minutes and wipe
off with a clean, damp cloth. Commercial
foam-type cleaners suitable for synthetic
leather materials may be used when
necessary.
CAUTIONStrong cleaning agents such as
solvents, paint thinners, window
cleaner or fuel must never be used
on leather or synthetic interior ma-
terials. Doing so could damage the
surface and cause the color to
deteriorate.
& Climate control panel, audio
panel, instrument panel,
console panel, and switches Use a soft, damp cloth to clean the climate
control panel, audio equipment, instru-
ment panel, center console, combination
meter panel, and switches. Appearance care/Cleaning the interior

Engine hood To open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their original
position.
2. Pull the hood release knob under the
instrument panel. 3. Release the secondary hood release
by moving the lever between the front
grille and the hood toward the left.
4. Lift up the hood.
To close the hood:
1. Lower the hood to a height of approxi-
mately 11.8 in (30 cm) above its closed
position and then let it drop.
2. After closing the hood, be sure the
hood is securely locked.
If this does not close the hood, release it
from a slightly higher position. Do not push
the hood forcibly to close it. It could
deform the metal. WARNINGAlways check that the hood is
properly locked before you start
driving. If it is not, it might fly open
while the vehicle is moving and
block your view, which may cause
an accident and serious bodily in-
jury.
CAUTION. When you open the engine hood,
do not stand the wiper blades up.
Furthermore, while the hood is
open, do not operate the wind-
shield wipers. Doing so could
result in damage to the engine
hood and wiper blades.
. Be extremely careful not to catch
fingers or other objects when
closing the engine hood.
. Do not push the hood forcibly to
close it. It could deform the
metal.
. Be extremely careful opening the
engine hood when the wind is
strong. The engine hood could
close suddenly, possibly causing
injuries from slamming.
. Do not install accessories other Maintenance and service/Engine hood

Maintenance and service/Engine oil
Except STI
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.
CAUTION
Thoroughly wipe off any engine oil that has spilled over the exhaust
pipe and/or under-cover. If spilled oil
is not promptly wiped up, the oil
could cause a fire.
6. Pour engine oil through the filler neck.
For the oil capacity (guideline), refer to
“ Engine oil ” F 12-4.
The oil quantity indicated above is only
guideline.
The necessary quantity of oil depends on
the quantity of oil that has been drained.
The quantity of drained oil differs slightly
depending on the temperature of the oil
and the time the oil is left flowing out. After
refilling the engine with oil, therefore, you
must use the level gauge to confirm that
the level is correct.
7. Start the engine and make sure that no
oil leaks appear around the drain plug.
8. Run the engine until it reaches the
normal operating temperature. Then stop
the engine and wait a few minutes to allow
the oil drain back. Check the oil level
again and if necessary, add more engine
oil.
CAUTION
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.
& Recommended grade and
viscosity CAUTIONUse only engine oil with the recom-
mended grade and viscosity.
Refer to “ Engine oil ” F 12-4.
NOTE Engine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. However,
in hot weather, oil of higher viscosity is
required to properly lubricate the en-
gine.
& Synthetic oil You must follow the oil and filter changing
intervals shown in the Warranty and
Maintenance booklet.
NOTE Synthetic oil of the grade and viscosity
noted in chapter 12 is the recom-
mended engine oil for optimum engine
performance. Conventional oil may be11-16

Brake booster If the brake booster does not operate as
described in the following, have it checked
by your SUBARU dealer.
1. With the engine off, depress the brake
pedal several times, applying the same
pedal force each time. The distance the
pedal travels should not vary.
2. With the brake pedal depressed, start
the engine. The pedal should move
slightly down to the floor.
3. With the brake pedal depressed, stop
the engine and keep the pedal depressed
for 30 seconds. The pedal height should
not change.
4. Start the engine again and run for
approximately one minute then turn it off.
Depress the brake pedal several times to
check the brake booster. The brake
booster operates properly if the pedal
stroke decreases with each depression.
NOTE When you depress the brake pedal
strongly or suddenly, you might feel
that lighter depression of the brake
pedal generates a greater braking
force. However, even though these
occur, they do not indicate any mal-
functions, and the brake assist system is operating properly.
Brake assist is not a system that brings
more braking ability to the vehicle
beyond its breaking capability.
Brake pedal Check the brake pedal free play and
reserve distance according to the main-
tenance schedule in the “ Warranty and
Maintenance Booklet ” .
& Checking the brake pedal
free play
1) 0.02 – 0.11 in (0.5 – 2.7 mm)
Stop the engine and firmly depress the
brake pedal several times. Lightly pull the
brake pedal up with one finger to check
the free play with a force of less than 2 lbf
(10 N, 1 kgf).
If the free play is not within proper
specification, contact your SUBARU deal-
er. Maintenance and service/Brake booster

Maintenance and service/Clutch pedal (MT models)
& Checking the brake pedal
reserve distance
1) More than 2.56 in (65 mm)
Depress the pedal with a force of approxi-
mately 66 lbf (294 N, 30 kgf) and measure
the distance between the upper surface of
the pedal pad and the floor.
When the measurement is smaller than
the specification, or when the pedal does
not operate smoothly, contact with your
SUBARU dealer. Clutch pedal (MT models) Check the clutch pedal free play and
reserve distance according to the main-
tenance schedule in the “ Warranty and
Maintenance Booklet ” .
& Checking the clutch function Check the clutch engagement and disen-
gagement.
1. With the engine idling, check that there
are no abnormal noises when the clutch
pedal is depressed, and that shifting into
1st or reverse feels smooth.
2. Start the vehicle by releasing the pedal
slowly to check that the engine and
transmission smoothly couple without
any sign of slippage. & Checking the clutch pedal
free play
1) 0.16 – 0.43 in (4.0 – 11.0 mm)
Lightly depress the clutch pedal down with
your finger until you feel resistance, and
check the free play.
If the free play is not within proper
specification, contact your SUBARU deal-
er.11-28

Hill start assist system Ensure that the Hill start assist system
operates properly under the following
circumstances.
1. Stop the vehicle on an uphill grade by
depressing the brake pedal (all models)
and clutch pedal (MT models only), with
the engine running.
2. Make sure that the vehicle does not
move backward for several seconds after
the brake pedal is released.
3. Then make sure the vehicle starts
climbing the grade by following the normal
starting procedures.
If the Hill start assist system does not
operate as described above, contact your
SUBARU dealer. Replacement of brake pad
and lining
The disc brakes have audible wear
indicators on the brake pads. If the brake
pads wear close to their service limit, the
wear indicator makes a very audible
scraping noise when the brake pedal is
applied.
If you hear this scraping noise each time
you apply the brake pedal, have the brake
pads serviced by your SUBARU dealer as
soon as possible.
CAUTION
. It is recommended that you dis-
connect the vehicle battery be- fore replacing the brake pad.
However, it is dangerous to dis-
connect the vehicle battery. We
recommend that you have your
SUBARU dealer replace the
brake pad.
. If you continue to drive despite
the scraping noise from the audi-
ble brake pad wear indicator, it
will result in the need for costly
brake rotor repair or replace-
ment.
& Breaking-in of new brake
pads (models with electronic
parking brake system) When replacing the brake pad, use only
genuine SUBARU parts. After replace-
ment, the new parts must be broken in as
follows.
! Brake pad
While maintaining a speed of 30 to 40
mph (50 to 65 km/h), step on the brake
pedal lightly. Repeat this five or more
times. Also, apply and release the electro-
nic parking brake five or more times.Maintenance and service/Hill start assist system
