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

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

Maintenance and service/Replacing bulbs
the headlight assembly by turning it clock-
wise.
4. Replace the bulb with new one. At this
time, use care not to touch the bulb
surface.
5. To install the bulb to the headlight
assembly, turn it to the reverse direction
until it clicks.
6. Reconnect the electrical connector.
7. Left-hand side: Set the washer fluid
filler pipe to the original place and secure it
by clip.
Right-hand side: Install the air intake
duct with clips.
& Low beam headlight (models
without LED headlights),
front side marker light (if
equipped), parking light
(models without LED head-
lights) and front turn signal
light
NOTE . If headlight aiming is required, con-
sult your SUBARU dealer for proper
adjustment of the headlight aim.
. It may be difficult to replace the
bulbs. Have the bulbs replaced by your
SUBARU dealer if necessary.
1. Start the engine and turn the steering wheel fully in the opposite direction of the
bulb to be replaced.
2. Stop the engine.
3. Remove the clips from the mud guard.
4. Pull off the mud guard. ! Low beam headlight
