Fuel SUBARU FORESTER 2017 SJ / 4.G Repair Manual

Appearance care/Cleaning the interior
&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.
CAUTION
Strong 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.
CAUTION
. Do not use organic solvents such
as paint thinners or fuel, or
strong cleaning agents that con-
tain those solvents. Doing so
could damage the surface and
cause the color to deteriorate.
. Do not use chemical solvents
that contain silicone on the vehi-
cle audio system, electrical com-
ponents of the air-conditioner or
any switches. If silicone adheres
to these parts, it may cause
damage to electrical compo-
nents.
& Monitor (if equipped)
To clean the audio/navigation/multi func-
tion display monitor, wipe it with a silicone
cloth or with a soft cloth. If the monitor is
extremely dirty, clean it with a soft cloth
moistened with neutral detergent then
carefully wipe off any remaining detergent.
CAUTION
. Do not spray neutral detergent
directly onto the monitor. Doing
so could damage the monitor ’s
components.
. Do not wipe the monitor with a
hard cloth. Doing so could
scratch the monitor.
. Do not use cleaning fluid that
contains thinner, fuel, or any
other volatile substance. Such
cleaning fluid could erase the
lettering on the switches at the
bottom of the monitor.

Maintenance precautions
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
section 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 that may activate the
system or it can render it inop-

Maintenance and service/Engine oil
Engine oil
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 thus
require refilling between maintenance
intervals:
. 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 brakin g 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 retailer who may perform a test
under controlled conditions.
& Checking the oil level
1. Park the vehicle on a level surface and
stop the engine. 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.
1) Oil level gauge
2) Oil filler cap
3) Oil filter
CAUTION
If the level gauge cannot be pulled
out easily, twist the level gauge right
and left, then pull it out. Otherwise,
you may be injured by accidentally
straining yourself.
2. Pull out the level gauge, wipe it clean,

and insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.
1) Full level
2) Low level
3) Approximately 1.1 US qt (1.0 liter, 0.9Imp 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 en-
gine 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.
& 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
extremely 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.
. If performing oil replacement your-
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 ”F 12-4.
NOTE
Engine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. However,
Maintenance and service/Engine oil

the cooling system and connections be
checked for leaks, damage, or looseness.
&Engine coolant
! Checking the coolant level
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 is
removed.
1) “FULL ”level mark
2) “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.
1) 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.
Maintenance and service/Cooling system
–CONTINUED –11-13

driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, replace it with a spare tire
as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.
&Tire inspection
Check on a daily basis that the tires are
free from serious damage, nails, and
stones. At the same time, check the tires
for abnormal wear.
Contact your SUBARU dealer immedi-
ately if you find any problem.
NOTE
. When the wheels and tires strike
curbs or are subjected to harsh treat-
ment as when the vehicle is driven on a
rough surface, they can suffer damage
that cannot be seen with the naked eye.
This type of damage does not become
evident until time has passed. Try not
to drive over curbs, potholes or on
other rough surfaces. If doing so is
unavoidable, keep the vehicle ’s speed
down to a walking pace or less, and
approach the curbs as squarely as
possible. Also, make sure the tires are
not pressed against the curb when you
park the vehicle.
. If you feel unusual vibration while
driving or find it difficult to steer the
vehicle in a straight line, one of the
tires and/or wheels may be damaged.
Drive slowly to the nearest authorized
SUBARU dealer and have the vehicle
inspected.
& Tire pressures and wear
Maintaining the correct tire pressures
helps to maximize the tires ’service lives
and is essential for good running perfor-
mance. Check and, if necessary, adjust
the pressure of each tire (including the
spare) at least once a month (for example,
during a fuel stop) and before any long journey.
Tire placard
The tire placard is located on the door
pillar on the driver
’s side. Check the tire
pressures when the tires are cold. Use a
pressure gauge to adjust the tire pres-
sures to the values shown on the tire
placard.
Driving even a short distance warms up
the tires and increases the tire pressures.
Also, the tire pressures are affected by the
outside temperature. It is best to check tire
pressure outdoors before driving the
vehicle.
When a tire becomes warm, the air inside
it expands, causing the tire pressure to
increase. Be careful not to mistakenly
release air from a warm tire to reduce its
Maintenance and service/Tires and wheels

Maintenance and service/Tires and wheels
pressure.
NOTE
.The air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3
kgf/cm
2) when the tire becomes warm.
. The tires are considered cold when
the vehicle has been parked for at least
3 hours or has been driven less than
one mile (1.6 km).
WARNING
Do not let air out of warm tires to
adjust pressure. Doing so will result
in low tire pressure.
Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally. .
Correct tire pressure (tread worn
evenly)
Roadholding is good, and steering is
responsive. Rolling resistance is low, so
fuel consumption is also lower. .
Abnormally low tire pressure (tread
worn at shoulders)Rolling resistance is high, so fuel con-
sumption is also higher.
