Cleaning the interiorUse a soft, damp cloth to clean the climate
control panel, audio equipment, instru-
ment panel, center console, combination
meter panel, and switches. (Do not use
organic solvents.)&Seat fabricRemove loose dirt, dust or debris with a
vacuum cleaner. If the dirt is caked on the
fabric or hard to remove with a vacuum
cleaner, use a soft brush then vacuum it.
Wipe the fabric surface with a tightly wrung
cloth and dry the seat fabric thoroughly. If
the fabric is still dirty, wipe using a solution
of mild soap and lukewarm water then dry
thoroughly.
If the stain does not come out, try a
commercially-available fabric cleaner.
Use the cleaner on a hidden place and
make sure it does not affect the fabric
adversely. Use the cleaner according to its
instructions.
CAUTION
When cleaning the seat, do not use
benzine, paint thinner, or any similar
materials. Doing so could damage
the surface and cause the color todeteriorate.
&Leather seat materialsThe leather used by SUBARU is a high
quality natural product which will retain its
distinctive appearance and feel for many
years with proper care.
Allowing dust or road dirt to build up on the
surface can cause the material to become
brittle and to wear prematurely. Regular
cleaning with a soft, moist, natural fiber
cloth should be performed monthly, taking
care not to soak the leather or allow water
to penetrate the stitched seams.
A mild detergent suitable for cleaning
woolen fabrics may be used to remove
difficult dirt spots, rubbing with a soft, dry
cloth afterwards to restore the luster. If
your SUBARU is to be parked for a long
time in bright sunlight, it is recommended
that the seats and head restraints be
covered, or the windows shaded, to pre-
vent fading or shrinkage. Make sure to
remove any seat covers and head restraint
covers when operating the vehicle.
Minor surface blemishes or bald patches
may be treated with a commercial leather
spray lacquer. You will discover that each
leather seat section will develop soft folds
or wrinkles, which is characteristic of
genuine leather.
&Synthetic leather upholsteryThe synthetic leather material used on the
SUBARU may be cleaned using mild soap
or detergent and water, after first vacuum-
ing or brushing away loose dirt. Allow the
soap to soak in for a few minutes and wipe
off with a clean, damp cloth. Commercial
foam-type cleaners suitable for synthetic
leather materials may be used when
necessary.
CAUTION
Strong cleaning agents such as
solvents, paint thinners, window
cleaner or fuel must never be used
on leather or synthetic interior ma-
terials. Doing so could damage the
surface and cause the color to
deteriorate.

Engine hoodTo open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their original
position.2. Pull the hood lock release knob under
the instrument panel.
3. Release the secondary hood release
by moving the lever between the front grille
and the hood toward the left.
4. Lift up the hood.
To close the hood:
1. Lower the hood to a height of approxi-
mately 11.8 in (30 cm) above its closed
position and then let it drop.
2. After closing the hood, be sure the
hood is securely locked.
If this does not close the hood, release it
from a slightly higher position. Do not push
the hood forcibly to close it. It could deform
the metal.
WARNING
Always check that the hood is
properly locked before you start
driving. If it is not, it might fly open
while the vehicle is moving and
block your view, which may cause
an accident and serious bodily in-
jury.
CAUTION
.When you open the engine hood,
do not stand the wiper blades up.
Furthermore, while the hood is
open, do not operate the wind-
shield wipers. Doing so could
result in damage to the engine
hood and wiper blades.
.Be extremely careful not to catch
fingers or other objects when
closing the engine hood.
.Do not push the hood forcibly to
close it. It could deform the metal.
.Be extremely careful opening the
engine hood when the wind is
strong. The engine hood could
close suddenly, possibly causing
injuries from slamming.

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 contain-
er.&Recommended clutch fluidRefer to“Fluids”F12-7.
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 boosterIf the brake booster does not operate as
described in the following, 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 one 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.NOTEWhen you depress the brake pedal
strongly or suddenly, you might feel
that lighter depression of the brake
pedal generates a greater braking
force. However, even though these
occur, they do not indicate any mal-
functions, and the brake assist systemis operating properly.
Brake assist is not a system that brings
more braking ability to the vehicle
beyond its breaking capability.

er.
&Checking the brake pedal re-
serve distance1) 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 according
to the maintenance schedule in the“War-
ranty and Maintenance Booklet”.&Checking the clutch functionCheck 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.

er.
Hill start assist systemEnsure that the Hill start assist system
operates properly under the following
circumstances.
1. Stop the vehicle on an uphill grade by
depressing the brake pedal (all models)
and clutch pedal (MT models only), with
the engine running.
2. Make sure that the vehicle does not
move backward for several seconds after
the brake pedal is released.
3. Then make sure the vehicle starts
climbing the grade by following the normal
starting procedures.
If the Hill start assist system does not
operate as described above, contact your
SUBARU dealer.
Replacement of brake pad
and liningThe disc brakes have audible wear in-
dicators 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
you apply the brake pedal, have the brake
pads serviced by your SUBARU dealer as
soon as possible.

CAUTION
.It is recommended that you dis-
connect the vehicle battery be-
fore replacing the brake pad.
However, it is dangerous to dis-
connect the vehicle battery. We
recommend that you have your
SUBARU dealer replace the brake
pad.
.If you continue to drive despite
the scraping noise from the audi-
ble brake pad wear indicator, it
will result in the need for costly
brake rotor repair or replace-
ment.&Breaking-in of new brake
pads (models with electronic
parking brake system)When replacing the brake pad, use only
genuine SUBARU parts. After replace-
ment, break in the new parts as follows.
!Brake pad
While maintaining a speed of 30 to 40 mph
(50 to 65 km/h), step on the brake pedal
lightly. Repeat this five or more times. Also,
apply and release the electronic parking
brake five or more times.
&Breaking-in of new brake
pads and linings (models
without electronic parking
brake system)When replacing the brake pad or lining,
use only genuine SUBARU parts. After
replacement, break in the new parts as
follows.
!Brake pad and lining
While maintaining a speed of 30 to 40 mph
(50 to 65 km/h), step on the brake pedal
lightly. Repeat this five or more times.
!Parking brake lining
1. Drive the vehicle at a speed of approxi-
mately 22 mph (35 km/h).
2. With the parking brake release button
pushed in, pull the parking brake lever
SLOWLY and GENTLY (pulling with a
force of approximately 33.7 lbf [150 N,
15.3 kgf]).
3. Drive the vehicle for approximately 220
yards (200 meters) in this condition.
4. Wait 5 to 10 minutes for the parking
brake to cool down. Repeat this proce-
dure.
5. Check the parking brake stroke. If the
parking brake stroke is out of the specified
range, adjust it by turning the adjusting nut
located on the parking brake lever.
Parking brake stroke:
7–8 notches / 45 lbf (200 N, 20.4 kgf)
WARNING
Select a safe location and situation
for break-in driving.
CAUTION
Pulling the parking brake lever too
forcefully may cause the rear wheels

Low tire pressure warning lightIf you adjust the tire pressures in a warm
garage and will then drive the vehicle in
cold outside air, the resulting drop in tire
pressures may cause the low tire pressure
warning light to illuminate. To avoid this
problem when adjusting the tire pressures
in a warm garage, inflate the tires to
pressures higher than those shown on
the tire placard. Specifically, inflate them
by an extra 1 psi (6.9 kPa, 0.07 kgf/cm
2) for
every difference of 108F (5.68C) between
the temperature in the garage and the
temperature outside. By way of example,
the following table shows the required tire
pressures that correspond to various out-
side temperatures when the temperature
in the garage is 608F (15.68C).Example:
Tire size: 245/40R18 97W
Standard tire pressures:
Front: 33 psi (230 kPa, 2.3 kgf/cm
2)
Rear: 32 psi (220 kPa, 2.2 kgf/cm2)
Garage temperature: 608F (15.68C)
Outside
temperatureAdjusted pressure
[psi (kPa, kgf/cm
2)]
Front Rear
308F(18C) 36 (250, 2.5) 35 (240, 2.4)
108F(128C) 38 (260, 2.6) 37 (255, 2.55)
108F(238C) 40 (275, 2.75)39 (270, 2.7)
If the low tire pressure warning light
illuminates when you drive the vehicle in
cold outside air after adjusting the tire
pressures in a warm garage, re-adjust the
tire pressures using the method described
above. Then, increase the vehicle speed
to at least 20 mph (32 km/h) and check to
see that the low tire pressure warning light
turns off a few minutes later. If the low tire
pressure warning light does not turn off,
the tire pressure monitoring system may
not be functioning normally. In this event,
go to a SUBARU dealer to have the
system inspected as soon as possible.
While the vehicle is driven, friction be-
tween tires and the road surface causes
the tires to warm up. After illumination ofthe low tire pressure warning light, any
increase in the tire pressures caused by an
increase in the outside air temperature or
by an increase in the temperature in the
tires can cause the low tire pressure
warning light to turn off.
System resetting is necessary when the
wheels are changed (for example, a switch
to snow tires) and new TPMS valves are
installed on the newly fitted wheels. Have
this work performed by a SUBARU dealer
following wheel replacement.
It may not be possible to install TPMS
valves on certain wheels that are on the
market. Therefore, if you change the
wheels (for example, a switch to snow
tires), use wheels that have the same part
number as the standard-equipment
wheels. Without four operational TPMS
valve/sensors on the wheels, the TPMS
will not fully function and the warning light
on the combination meter will illuminate
steadily after blinking for approximately
one minute.
When a tire is replaced, adjustments are
necessary to ensure continued normal
operation of the tire pressure monitoring
system. As with wheel replacement, there-
fore, you should have the work performed
by a SUBARU dealer.
