11-16. Brake BoosterThe brake booster utilizes the vacuum
produced by the vacuum pump to reduce
the force required to depress the brake
pedal.
The vacuum in the brake booster may be
insufficient if the brake pedal is depressed
when the engine is stopped or after the
vehicle has been parked for a long period
of time. It such cases, it is necessary to
depress the brake pedal using greater
force than usual.

Parking Brake Stroke
357
Maintenance and Service11
The disc brakes have audible wear indica-
tors 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.■
Breaking-in of New Brake
Pads and Linings
When replacing the brake pad or lining,
use only genuine SUBARU parts. After
replacement, the new parts must be
broken in 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 approx-
imately 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 lever travel. If
the parking brake lever travel is out of the
specified range, adjust it by turning the
adjusting nut located on the parking brake
lever.
11-20. Parking Brake StrokeCheck the parking brak
e stroke according
to the maintenance schedule in the
“Warranty and Maintenance Booklet”.

7 – 8 notches / 45 lbf (200 N, 20.4 kgf)
WARNING
A safe location and situation should
be selected for break-in driving.
CAUTION
Pulling the parking brake lever too
forcefully may cause the rear
wheels to lock. To avoid this, be cer-
tain to pull the lever up slowly and
gently.

Tires and Wheels
360
■
Tire Inspection
Check on a daily basis that the tires
are free from serious damage, nails,
and stones. At the same time, check
the tires for abnormal wear.
Contact your SUBARU dealer
immediately if you find any problem.NOTEWhen the wheels and tires
strike curbs or are subjected to
harsh treatment as when the
vehicle is driven on a rough surface, they can suffer damage
that cannot be seen with the
naked eye. This type of damage
does not become evident until
time has passed. Try not to drive
over curbs, potholes or on other
rough surfaces. If doing so is
unavoidable, keep the vehicle’s
speed down to a walking pace or
less, and approach the curbs as
squarely as possible. Also, make
sure the tires are not pressed
against the curb when you park
the vehicle.

If you feel unusual vibration
while driving or find it difficult to
steer the vehicle in a straight line,
one of the tires and/or wheels
may be damaged. Drive slowly to
the nearest authorized SUBARU
dealer and have the vehicle
inspected.
 Tires should be replaced if:
– You have tire damage such
as cuts, splits, cracks deep
enough to expose the fabric or
bulges indicating internal
damage
WARNING
If the low tire pressure warning light
does not illuminate briefly after the
ignition switch is turned ON or the
light illuminates steadily after blink-
ing for approximately one minute,
you should have your Tire Pressure
Monitoring System checked at a
SUBARU dealer as so on as possi-
ble.If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Oth-
erwise an accident involving
serious vehicle damage and serious
personal injury could occur.1) Keep driving straight ahead while gradually reducing speed.2) Slowly pull off the road to a safeplace.If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose ai r rapidly. If you
have a flat tire, replace it with a
spare tire as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the low tire pres-
sure warning light will illuminate
steadily after blinking for approxi-
mately one minute. This indicates
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possi-
ble for tire and sensor replacement
and/or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.

Alloy Wheels
366NOTEWhen any of the wheels are removed
and replaced for tire rotation or to
change a flat tire, always check the
tightness of the wheel nuts after driv-
ing approximately 600 miles (1,000
km). If any nut is loose, tighten it to the
specified torque.
11-22. Alloy WheelsAlloy 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.
 When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for alloy wheels.
11-23. Windshield WasherFluid1) “LOW” positionThe washer fluid level can be checked by
observing the position of the level on the
liquid-covered holes in the gauge.
If the level falls below the second hole
from the bottom (the “LOW” position), add
washer fluid.
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.
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
during turns. The resulting loss of
vehicle control could lead to an
accident.
