The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the “Warranty and Mainte-
nance Booklet”. For details, read the
separate “Warranty and Maintenance
Booklet”.

Canada models
The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the “Warranty and Service
Booklet”. For details, read the separate
“Warranty and Service Booklet”.

Except for U.S. and Canada models
Some items of your vehicle are required to
be serviced at scheduled intervals. For
details about your maintenance schedule,
read the separate “Warranty and Main-
tenance Booklet”.

NOTE

For models with a multi-function dis-
play (color LCD), you can set a remin-
der to be displayed when a scheduled
maintenance item is almost due. For
details, refer to “Maintenance settings”
FP222.

11-2. Maintenance precau-
tions

When 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

Always select a safe area when

performing maintenance on your
vehicle.

Always be very careful to avoid

injury 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
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.

Do not tamper with the wiring of

the SRS airbag system or seat-
belt pretensioner system, or at-
tempt to take its connectors

apart, as this may activate the
system or render it inoperative.
NEVER use a circuit tester for
this wiring. If your SRS airbag or
seatbelt pretensioner needs ser-
vice, consult your nearest
SUBARU dealer.

NOTE

SUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against
performing these services on a
SUBARU vehicle. Non-SUBARU ap-
proved flushing systems use chemi-
cals and/or solvents which have not
been tested or approved by SUBARU.
SUBARU warranties do not cover any
part of the vehicle which is damaged by
adding or applying chemicals and/or
solvents other than those approved or
recommended by SUBARU.

Before checking or servicing
in the engine compartment

WARNING

Always stop the engine and apply

the parking brake firmly to pre-
vent the vehicle from moving.

Always let the engine cool down.

Engine parts become very hot
when the engine is running and
remain hot for some time after the
engine has stopped.

Do not spill engine oil, engine

coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.

When the ignition switch is in the

“ON” position, the cooling fan
may operate suddenly even when
the engine is stopped. If your
body or clothes come into con-
tact with a rotating fan, that could
result in serious injury. To avoid
risk of injury, perform the follow-
ing precautions.

– Models with push-button start

system:
Always turn the push-button
ignition switch to the “OFF”
position and confirm that the
operation indicator on the
switch is turned off. Then take
the access key fob out from
the vehicle.

– Models without push-button

start system:
Always remove the key from
the ignition switch.

Before performing any servicing

on a vehicle equipped with a
remote engine start system (a
dealer option), temporarily place
the remote engine start system in
service mode to prevent it from
unexpectedly starting the engine.

When checking or servicing
in the engine compartment

CAUTION

Do not touch the engine cover

while checking the components
in the engine compartment.
Doing so may cause your hand
to slip off the cover and result in

an unexpected injury.

Do not touch the oil filter until the

engine has cooled down comple-
tely. Doing so may result in a burn
or other injury. Note that the oil
filter becomes very hot when the
engine is running and remains
hot for some time after the engine
has stopped.

When checking or servicing
in the engine compartment
while the engine is running

CAUTION

If the level gauge cannot be

pulled out easily, twist the level
gauge right and left, then gently
pull it out. Otherwise, you may be
injured accidentally straining
yourself.

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.

Engine oil consumption

Some engine oil will be consumed while
driving. The rate of consumption can be
affected by such factors as transmission
type, driving style, terrain and tempera-
ture. Under the following conditions, oil
consumption can be increased and may
require refilling between maintenance in-
tervals.

When the engine is new and within the

break-in period.
.

When the engine oil is of lower quality.

When the incorrect oil viscosity is used.

When engine braking is employed

(repeatedly).
.

When the engine is operated at high

engine speeds (for extended periods of
time).
.

When the engine is operated under

heavy loads (for extended periods of time).
.

When towing a trailer

When the engine idles for extended

periods of time.
.

When the vehicle is operated in stop-

and-go and/or heavy traffic situations.
.

When the vehicle is used under severe

thermal conditions.
.

When the vehicle accelerates and

decelerates frequently.

Under these or similar conditions, you
should check your oil at least every 2nd
fuel fill-up and change your engine oil more
frequently. Different drivers in the same
car may experience different results. If
your oil consumption rate is greater than
expected, contact your authorized
SUBARU dealer who may perform a test
under controlled conditions.

Approximately 1.1 US qt (1.0 liter, 0.9 Imp
qt) from low level to full level

4. Pull out the oil level gauge again.
5. Check the oil levels on both sides of the
level gauge. The engine oil level must be

judged by the lowest of the two levels. If
the oil level is below the low level mark,
add oil so that the full level is reached.

CAUTION

Be careful not to touch the engine

oil filter when removing the oil
filler cap. Doing so may result in a
burn, a pinched finger, or may
cause some other injury.

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.

To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level is
correct.

NOTE

To prevent overfilling the engine oil,

do not add any additional oil above the
upper level when the engine is cold.

The engine low oil level warning light

may stay illuminated when the engine
is started straight after topping up or
changing the engine oil. In such cases,
park the vehicle on a level surface and
wait for more than a minute until the oil
level settles, after which the warning
light will turn off. Refer to “Engine low
oil level warning light” FP170.

Changing the oil and oil filter

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 ex-
tremely cold weather.

NOTE

Changing the engine oil and oil filter

should be performed by a well-trained
expert. Contact your SUBARU dealer
for changing the engine oil and oil filter.
Fully trained mechanics are on standby
at a SUBARU dealer to utilize the
special tools, spare parts and recom-
mended oil for this work, and also, used
oils are properly disposed of.
.

self, observe the local regulations and
dispose of waste oil properly.

Recommended grade and
viscosity

CAUTION

Use only engine oil with the recom-
mended grade and viscosity.

Refer to “Engine oil” FP489.

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 should use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using syn-
thetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner’s Manual. Refer to “Engine
oil” FP489. Also, 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 be
used if synthetic oil is unavailable.

11-7. Cooling system

Safety precautions

WARNING

Never attempt to remove the radiator
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 boiling hot coolant when
the cap is removed.

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 add the coolant for
any reason, use only SUBARU
Super Coolant.

If the SUBARU Super Coolant is
diluted with another brand or

Cooling system

452

(455,1)

北米Model "A8240BE-B" EDITED: 2018/ 7/ 5

type, the maintenance interval is
shortened to that of the mixing
coolant.

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 coolant temperature high
warning light blinks or illuminates in RED,
the cooling fan circuit may be defective.
Refer to “Coolant temperature low indica-
tor light/Coolant temperature high warning
light” FP168.

Check the fuse and replace it if necessary.
Refer to “Fuses” FP474 and “Fuse panel
located in the engine compartment”
FP497.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer.

If frequent addition of coolant is necessary,
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.

Engine coolant

Checking the coolant level

WARNING

“FULL” level mark

“LOW” level mark

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
coolant up to just below the filler neck as
shown in the following illustration.

Fill up to this level.

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.

CAUTION

Be careful not to spill engine

coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off.

Do not splash the engine coolant

over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.

Changing the coolant

It may be difficult to change the coolant.
Have the coolant changed by your
SUBARU dealer if necessary.

The coolant should be changed according
to the maintenance schedule in the “War-
ranty and Maintenance Booklet”.

11-8. Air cleaner element

WARNING

Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters in-
take air but also stops flames if the
engine backfires. If the air cleaner
element is not installed when the
engine backfires, you could be
burned.

CAUTION

When replacing the air cleaner ele-
ment, use a genuine SUBARU air
cleaner element. If it is not used, it
will cause a negative effect to the
engine.

The air cleaner element functions as a filter
screen. When the element is perforated or
removed, engine wear will be excessive
and engine life shortened.

It is not necessary to clean or wash the air
cleaner element.
