2016 SUBARU LEGACY maintenance schedule

Maintenance and service/Spark plugs
Spark plugs
It may be difficult to replace the spark
plugs. It is recommended that you have
the spark plugs replaced by your
SUBARU dealer.
The spark plugs should be replaced
according to the maintenance schedule
in the“Warranty and Maintenance Book-
let”.
&Recommended spark plugs
Refer to“Electrical system”F12-9.
Drive belts
It is unnecessary to check the deflection of
the drive belt periodically because your
engine is equipped with an automatic belt
tension adjuster. However, replacement of
the belt should be done according to the
maintenance schedule in the“Warranty
and Maintenance Booklet”. Consult your
SUBARU dealer for replacement.
If the belt is loose, cracked or worn,
contact your SUBARU dealer.
Manual transmission oil
It is unnecessary to check the manual
transmission oil level. However, if neces-
sary, consult your SUBARU dealer for
inspection.
&Recommended grade and
viscosity
Each oil manufacturer has its own base
oils and additives. Never use different
brands together. For details, refer to
“Manual transmission, front differential
and rear differential gear oil”F12-7.
11-18

Continuously variable trans-
mission fluid
There is no fluid level gauge. It is
unnecessary to check the continuously
variable transmission fluid level. However,
if necessary, consult your SUBARU dealer
for inspection.
Front differential gear oil
(CVT models) and rear differ-
ential gear oil
It is not necessary to check the gear oil
level. Check that there are no cracks,
damage or leakage. However, the oil
inspection should be performed according
to the maintenance schedule in the
“Warranty and Maintenance Booklet”.
Consult your SUBARU dealer for details.
&Recommended grade and
viscosity
Each oil manufacturer has its own base
oils and additives. Never use different
brands together. For details, refer to
“Manual transmission, front differential
and rear differential gear oil”F12-7.
CAUTION
Using a differential gear oil other
than the specified oil may cause a
decline in vehicle performance.
Brake fluid
&Checking the fluid level
WARNING
.Never let brake fluid contact your
eyes because brake fluid can be
harmful to your eyes. If brake
fluid gets in your eyes, immedi-
ately flush them thoroughly with
clean water. For safety, when
performing this work, wearing
eye protection is advisable.
.Brake fluid absorbs moisture
from the air. Any absorbed moist-
ure can cause a dangerous loss
of braking performance.
.If the vehicle requires frequent
refilling, there may be a leak. If
you suspect a problem, have the
vehicle checked at your SUBARU
dealer.
CAUTION
.When adding brake fluid, be care-
ful not to allow any dirt into the
reservoir.
.Never splash the brake fluid over
painted surfaces or rubber parts.
Maintenance and service/Continuously variable transmission fluid
–CONTINUED–11-19

Maintenance and service/Brake booster
Check the fluid level monthly.
Check the fluid level on the outside of the
reservoir. Because this reservoir is used
for both the brake and clutch systems and
has chambers for each system, be sure to
check the fluid level for the clutch system
at theinboard side of the reservoir
(shaded area in the illustration). If the fluid
level is below“MIN”, add the recom-
mended clutch fluid to“MAX”.
Use only clutch fluid from a sealed
container.
&Recommended clutch fluid
Refer to“Fluids”F12-8.
CAUTION
Never use different brands of clutch
fluid together. Also, avoid mixing
DOT 3 and DOT 4 brake fluids even if
they are the same brand.
Brake booster
If the brake booster does not operate as
described in the following procedure, 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 1 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.
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.
11-22

&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) 0.19–0.44 in (5–11 mm)
Lightly press 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.
Maintenance and service/Clutch pedal (MT models)11-23

Maintenance and service/Tires and wheels
Vehicles equipped with unidirectional tires
1) Front
Tire wear varies from wheel to wheel.
Move the tires to the positions shown in
the illustration each time they are rotated.
For the tire rotation schedule, refer to the
“Warranty and Maintenance Booklet”.
Replace any damaged or unevenly worn
tire at the time of rotation. After tire
rotation, adjust the tire pressures and
make sure the wheel nuts are correctly
tightened.
After driving approximately 600 miles
(1,000 km), check the wheel nuts again
and retighten any nut that has become
loose.
&Tire replacement
The wheels and tires are important and
integral parts of your vehicle’s design;
they cannot be changed arbitrarily. The
tires fitted as standard equipment are
optimally matched to the characteristics
of the vehicle and were selected to give
the best possible combination of running
performance, ride comfort, and service
life. It is essential for every tire to have a
size and construction matching those
shown on the tire placard and to have a
speed symbol and load index matching
those shown on the tire placard.
Using tires of a non-specified size detracts
from controllability, ride comfort, braking
performance, speedometer accuracy and
odometer accuracy. It also creates incor-
rect body-to-tire clearances and inappro-
priately changes the vehicle’s ground
clearance.
All four tires must be the same in terms of
manufacturer, brand (tread pattern), con-
struction, and size. You are advised to
replace the tires with new ones that are
identical to those fitted as standard equip-
ment.
For safe vehicle operation, SUBARU
recommends replacing all four tires at
the same time.WARNING
.When replacing or installing
tire(s), all four tires must be the
same for the following items.
(a) Size
(b) Circumference
(c) Speed symbol
(d) Load index
(e) Construction
(f) Manufacturer
(g) Brand (tread pattern)
(h) Degrees of wear
For items (a) to (d), you must
obey the specification that is
printed on the tire placard. The
tire placard is located on the
driver’s door pillar.
If all four tires are not the same in
items (a) to (h), it may lead to
serious mechanical damage to
the drive train of your car and
affect the following factors.
—Ride
—Handling
—Braking
—Speedometer/Odometer
