Maintenance schedule The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the “ Warranty and Main-
tenance Booklet ” .
For details of your maintenance schedule,
read the separate “ Warranty and Main-
tenance Booklet ” .
NOTE For models with a multi function dis-
play, you can set a reminder to be
displayed when a scheduled mainte-
nance item is almost due. For details,
refer to “ Maintenance settings ” F 3-79.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
. Testing of an All-Wheel Drive
model must NEVER be per-
formed on a single two-wheel
dynamometer or similar appara-
tus. Attempting to do so will
result in transmission damage
and in uncontrolled vehicle
movement and may cause an
accident or injuries to persons
nearby.
. 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 toMaintenance and service/Maintenance schedule

Maintenance and service/Clutch pedal (MT models)
& 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) 0.16 – 0.43 in (4.0 – 11.0 mm)
Lightly depress the clutch pedal down with
your finger until you feel resistance, and
