2016 SUBARU LEGACY engine

&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/Windshield washer fluid
Windshield washer fluid
CAUTION
Never use engine coolant as washer
fluid because it could cause paint
damage.
Windshield washer fluid warning indicator
When there is only a small amount of
washer fluid remaining, the windshield
washer fluid warning indicator will appear.
When this occurs, refill the washer fluid as
follows.
1)“FULL”mark
Remove the washer tank filler cap, then
add fluid until it reaches the“FULL”mark
on the tank.
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean
water.
In areas where water freezes in winter,
use an anti-freeze type windshield washer
fluid. SUBARU Windshield Washer Fluid
contains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it
is diluted, as indicated in the following
table.

ConcentrationFreezing
Temperature
30%
10.48F(−128C)
50%−48F(−208C)
100%−498F(−458C)
CAUTION
Never use engine coolant as washer
fluid because it could cause paint
damage.
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block the
nozzles.

Maintenance and service/Fuses
distilled water.Fuses
CAUTION
Never replace a fuse with one hav-
ing a higher rating or with material
other than a fuse because serious
damage or a fire could result.
The fuses are designed to melt during an
overload to prevent damage to the wiring
harness and electrical equipment. The
fuses are located in two fuse boxes.
One is located under the instrument panel
behind the fuse box cover on the driver’s
seat side. To remove the cover, pull it out.
The other one (main fuse box) is housed
in the engine compartment.
1) Spare fuses
The spare fuses are stored in the main
fuse box cover in the engine compart-
ment.
11-38

The fuse puller is stored in the main fuse
box in the engine compartment. To pick up
the fuse puller, pull it out while pinching
the puller head with your fingers.
1) Good
2) Blown
If any lights, accessories or other electrical
controls do not operate, inspect the
corresponding fuse. If a fuse has blown,
replace it.
1. Turn the ignition switch to the“LOCK”/
“OFF”position and turn off all electrical
accessories.
2. Remove the fuse box cover.
3. Determine which fuse may be blown.
Look at the back side of each fuse box
cover and refer to“Fuses and circuits”
F12-10.
4. Pull out the fuse with the fuse puller.
5. Inspect the fuse. If it has blown,
replace it with a spare fuse of the same
rating.
6. If the same fuse blows again, this
indicates that its system has a problem.Contact your SUBARU dealer for repairs.

&Engine oil
For the checking, adding and replacing procedure or other details, refer to“Engine oil”F11-11.
NOTEThe procedure for changing the engine oil and oil filter should be performed by a properly-trained expert. It is recommended
that you have this service performed by your SUBARU dealer.
!Approved engine oil
Always use the SUBARU approved engine oil. For further details, please contact your SUBARU dealer.
If the approved engine oil is unavailable, use the alternative engine oil described on the next page.
!Alternative engine oil
If the SUBARU approved oil is unavailable, the following alternative oil can be used.
NOTE
.Each quantity indicated is only a guideline. The necessary quantity for replacement may differ slightly depending on the
temperature and other factors.
.In choosing an oil, you want the proper quality and viscosity, as well as one that will enhance fuel economy. Oils of lower
viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the
engine. The following table lists the recommended viscosities and applicable temperatures.
.When adding oil, different brands may be used together as long as they are the same API classification and SAE viscosity
as those recommended by SUBARU.
