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) 0.02 –0.08 in (0.5 –2.0 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. Replacement of brake pad
and lining
CAUTION
If you continue to drive despite the
scraping noise from the audible
brake pad wear indicator, it will
result in the need for costly brake
rotor repair or replacement.
The right front disc brake and the right rear
disc brake have audible wear indicators
on the brake pads. If the brake pads wear
close to their service limit, the wear
indicator makes a very audible scraping
noise when the brake pedal is applied.
If you hear this scraping noise each time

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 of
vehicle control could lead to anaccident. 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.. Be sure to fit tire chains on uniformly
and completely around the tire, otherwise
the chains may scratch the wheel. . When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for aluminum wheels. Windshield washer fluid
CAUTION
Never use engine coolant as washer
fluid because it could cause paintdamage.
If you spray washer fluid on the windshield
but the supply of washer fluid appears to
diminish, check the level of washer fluid in
the tank. Maintenance and service

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.
Open the lid that is located above the
hood release knob and pull it toward you
to remove it.
The other one is housed in the engine compartment.
The spare fuses are stored in the main
fuse box cover in the engine compart-ment.
The fuse puller is stored in the main fuse
box in the engine compartment.
