2016 SUBARU LEGACY oil change

Seat, seatbelt and SRS airbags/Front seatbelt pretensioners
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 moderate to severe frontal and
side collisions and rollover accidents.
The pretensioner sensor also serves as
follows.
.SRS frontal airbag sensor
.Side impact sensor
.Rollover sensor
If the sensor detects a certain predeter-
mined amount of force during frontal or
side collisions or rollover accidents, the
front seatbelt is quickly drawn back in by
the retractor to take up the slack so that
1-24

Climate control/Air filtration system
allow outside air to circulate into the
heated interior. This results in quicker
cooling by the air conditioner. Keep the
windows closed during the operation of
the air conditioner for maximum cooling
efficiency.
&Lubrication oil circulation in
the refrigerant circuit
Operate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil.
&Checking air conditioning
system before summer sea-
son
Check the air conditioner unit for refriger-
ant leaks, hose conditions, and proper
operation each spring. Have the air con-
ditioning system checked by your
SUBARU dealer.
&Cooling and dehumidifying in
high humidity and low tem-
perature weather condition
Under certain weather conditions (high
relative humidity, low temperatures, etc.) a
small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicateany problem with the air conditioning
system.
&Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving on a steep
upgrade.
&Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the meth-
od of adding, changing or checking the
refrigerant is different from the method for
CFC12 (freon). Consult your SUBARU
dealer for service. Repairs needed as a
result of using the wrong refrigerant are
not covered under warranty.
Air filtration system (if
equipped)
Your vehicle’s air conditioning system is
equipped with an air filtration system.
Replace the air filter element according
to the replacement schedule shown in the
following table. This schedule should be
followed to maintain the filter’sdust
collection ability. Under extremely dusty
conditions, the filter should be replaced
more frequently. Have your filter checked
or replaced by your SUBARU dealer. For
replacement, use only a genuine
SUBARU air filter kit. For the replacement
schedule, refer to the“Warranty and
Maintenance Booklet”.
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter.
.Reduction of the airflow through
the vents.
.Windshield gets easily fogged or
misted.
NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-

damaged or additional transmitters are
desired (the system will accept up to eight
transmitters). New remote engine start
transmitters can be programmed accord-
ing to the following procedure.
1. Open the driver’s door (the driver’s
door must remain opened throughout the
entire process).
2. Depress and hold the brake pedal.
3. Turn the ignition switch to“ON”then
“LOCK”, back to“ON”then“LOCK”, back
to“ON”then“LOCK”, then back to“ON”
again and leave the ignition“ON”through-
out the programming process.
4. The system will flash the side marker
lights, tail lights and parking lights and
honk the horn three times, indicating that
the system has entered the transmitter
learn mode.
5. Press and release the“
”button on
the transmitter that you want to program.
6. The system will flash the side marker
lights, tail lights and parking lights and
honk the horn one time, indicating that the
system has learned the transmitter. Upon
successful programming, the remote start
confirmation transmitter button will flash
one time.
7. Repeat step 5 for any additional
transmitters (the system will accept up toeight transmitters).
8. The system will exit the transmitter
learn mode if the key is turned to the
“LOCK”position, the door is closed or
after 2 minutes.
&System maintenance
NOTE
For models without“keyless access
with push-button start system”:
In the event that the vehicle’s battery is
replaced, discharged or disconnected,
it will be necessary to start the vehicle
a minimum of one time using the key
prior to activating the remote engine
start system. This is required to allow
the vehicle electronic systems to re-
synchronize.
!Changing the batteries
CAUTION
.Do not let dust, oil or water get on
or in the remote engine start
transmitter when replacing the
battery.
.Be careful not to damage the
printed circuit board in the re-
mote engine start transmitter
when replacing the battery..Be careful not to allow children to
touch the battery and any re-
moved parts; children could
swallow them.
.There is a danger of explosion if
an incorrect replacement battery
is used. Replace only with the
same or equivalent type of bat-
tery.
.Batteries should not be exposed
to excessive heat such as sun-
shine, fire or the like.
For models with“keyless access with
push-button start system:
Perform the procedure described in“Re-
placing battery of access key”F11-50.
For models without“keyless access
with push-button start system”:
The 3-volt lithium battery (model CR-
2032) supplied in your remote engine start
transmitter should last approximately one
year, depending on usage. When the
battery begins to weaken, you will notice
a decrease in range (distance from the
vehicle that your remote control operates).
Follow the instructions below to change
the remote engine start transmitter battery.

To upshift to the next higher gear position,
pull the shift paddle that has“+”indicated
on it. To downshift to the next lower gear
position, pull the shift paddle that has“–”
indicated on it.
To deselect the manual mode, return the
select lever to the“D”position from the“M”
position.
While driving with the select lever in the
“D”position, if you change gears by
operating the shift paddle, the gear posi-
tion indicator light illuminates and shows
the current gear condition.
CAUTION
Do not place or hang anything on
the shift paddles. Doing so may
result in accidental gear shifting.
NOTE
Please read the following points care-
fully and bear them in mind when using
the manual mode.
.If you attempt to shift down when
the engine speed is too high, i.e., when
a downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible.
.If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond.
.You can perform a skip-shift (for
example, from 4th to 2nd) by operating
the shift paddle twice in rapid succes-
sion.
.The transmission automatically se-
lects 1st gear when the vehicle stops
moving.
.If the temperature of the transmis-
sion fluid becomes too high, the“AT
OIL TEMP”warning light will illuminate.
Immediately stop the vehicle in a safe
place and let the engine idle until thewarning light turns off.
&Driving tips
.On a road surface where there is a risk
of wheelspin (for example, a snow- or
gravel-covered road), you can pull away
from a standstill safely and easily by first
selecting the 2nd gear of the manual
mode.
.Always apply the foot or parking brake
when the vehicle is stopped in the“D”or
“R”position.
.Always apply the parking brake when
parking your vehicle. Do not hold the
vehicle with only the transmission.
.Do not keep the vehicle in a stationary
position on an uphill grade by using the
“D”position. Use the brake instead.
.The engine may, on rare occasions,
knock when the vehicle rapidly acceler-
ates or rapidly pulls away from a standstill.
This phenomenon does not indicate a
malfunction.
.A slight reduction in output torque may
occur in the models with a 3.6 L engine
before the engine warms up.

Engine oil
CAUTION
.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.
.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. 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 braking is employed
.When the engine is operated at high
engine speeds
.When the engine is operated under
heavy loads
.When towing a trailer
.When the engine idles for long 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. If your oil consumption
rate is greater than 1 quart every 1,200
miles or 1 liter every 2,000 kilometers,
contact your SUBARU dealer 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.

CAUTION
.For 2.5 L models, 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.
.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 by accidentally straining
yourself.
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 full
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”.
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”F12-4.
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 should use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using
synthetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner’s Manual. Refer to“Engine
oil”F12-4. 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.

Maintenance and service/Cooling system
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 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 top off the coolant
for any reason, use only
SUBARU Super Coolant.
If the SUBARU Super Coolant is
diluted with another brand ortype, 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 engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Refer to“Temperature gauge”
F3-11.
Check the fuse and replace it if necessary.
Refer to“Fuses”F11-38 and“Fuses and
circuits”F12-10. 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 bechecked for leaks, damage, or looseness.
&Engine coolant
!Checking the coolant level
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
as required.
3. After refilling the reserve tank and the
radiator, reinstall the caps and check that
the rubber gaskets inside the radiator cap
are in the proper position.

calibration
—Clearance between the body
and tires
It also may be dangerous and
lead to loss of vehicle control,
and it can lead to an accident.
.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 ofvehicle control could lead to an
accident.
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 is removed
and replaced for tire rotation or to change
a flat, 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.
