Hill-holder System
15.Hill-holder System
A: INSPECTION AND ADJUSTMENT
1) Confirm the stopping and starting performance
by activating the hill-holder on an uphill road of 3°
or higher inclination.
(1) When the vehicle does not stop;
Tighten the adjusting nut of PHV cable.
(2) When the vehicle does not start properly;
A; When the hill-holder is released later than en-
gagement of clutch (engine tends to stall): Loos-
en the adjusting nut gradually until smooth
starting is enabled.
B; When the hill-holder is released earlier than
engagement to clutch (vehicle slips down slight-
ly): Tighten the adjusting nut so that hill-holder is
released later than engagement of clutch (status
in A). Then make adjustment the same as in A.
CAUTION:
 Whenever turning the adjusting nut, hold the
inner cable with pliers to prevent it from turn-
ing.
 Replace the pressure hold valve (PHV) or
PHV cable with a new one, if they are defective
and/or damaged.

ATF
16.ATF
A: INSPECTION
CAUTION:
The level of ATF varies with fluid temperature.
Pay attention to the fluid temperature when
checking ATF level.
1) Raise the ATF temperature by driving a distance
of 5 to 10 km (3 to 6 miles). Otherwise, idle the en-
gine to raise ATF temperature to 70 — 80°C (158
— 176°F) on Subaru Select Monitor. 4AT(H4SO)-18, READ CURRENT DATA, OPERA-
TION, Subaru Select Monitor.>
2) Make sure the vehicle is level.
3) After selecting all positions (P, R, N, D, 3, 2, 1),
set the select lever in “P” range. Measure the ATF
level with the engine idling for one or two minutes.
4) Make sure that ATF level is above the center of
upper and lower level.
NOTE:
When the transmission is hot, the level should be
above the center of upper and lower marks, and
when it is cold, the level should be found below the
center of these two marks.
5) If the ATF level is below the center between up-
per and lower marks, add the recommended ATF
until the ATF level is found above the center be-
tween upper and lower marks.
CAUTION:
 Use care not to exceed the upper limit level.
 Remember that the addition of ATF to the up-
per limit mark when the transmission is cold
will result in overfilling of ATF, causing a trans-
mission failure.
6) Check ATF level after raising ATF temperature
to 70 — 80°C (158 — 176°F) by running the vehicle
or by idling the engine again.7) Check the ATF for leaks.
Check for leaks in the transmission. If there are
leaks, it is necessary to repair or replace gasket, oil
seals, plugs or other parts.

Brake Line
18.Brake Line
A: INSPECTION
1. BRAKE LINE
1) Check scratches, swelling, corrosion, traces of
fluid leakage on the brake hoses or pipe joints.
2) Check the possibility of adjacent parts interfering
with brake pipes or hoses during driving, and loose
connections or clamps.
3) Check any trace of fluid leakage, scratches, etc.
on the master cylinder, wheel cylinder and pres-
sure control valve.
NOTE:
 When the brake fluid level in the reservoir tank is
lower than the specified limit, the brake fluid warn-
ing light on the combination meter will come on.
 Visually check the brake hose (using a mirror
where it is difficult to see) for any damage.
B: CHECKING
1. SERVICE BRAKE
1) Check the free play of brake pedal with a force of
less than 10 N (1 kgf, 2 lb).
Brake pedal free play:
0.5 — 2.0 mm (0.02 — 0.08 in)
2) If the free play is out of specifications above, ad-
just the brake pedal as follows.
(1) Be sure the engine is off. (No vacuum is ap-
plied to brake booster.)
(2) There should be play between brake boost-
er clevis and pin at brake pedal installing por-
tion.
[Depress brake pedal pad with a force of less
than 10 N (1 kgf, 2 lb) to a stroke of 0.5 to 2.0
mm (0.02 to 0.08 in).]
(3) Depress the surface of brake pad by hand.

(4) If there is no free play between clevis pin
and clevis, turn the brake switch adjusting nut
until the clearance between stopper and screw
of brake switch becomes 0.3 mm (0.012 in).
3) Check the pedal stroke.
While the engine is idling, depress the brake pedal
with a 490 N (50 kgf, 110 lb) load and measure the
distance between brake pedal and steering wheel.
With the brake pedal released, measure the dis-
tance between pedal and steering wheel again.
The difference between the two measurements
must be less than specified value. If the distance is
more than specified value, there is possibility of air
inside the hydraulic unit.
Brake pedal reserve distance: A
For Australia model
105 mm (4.13 in)/ 490 N (50 kgf , 110 lb) or less
Except for Australia model
90 mm (3.54 in)/ 490 N (50 kgf , 110 lb) or less4) Check to see if air is in the hydraulic brake line
by the feel of pedal operation. If air appears to exist
in the line, bleed it from the system.
5) Check for even operation of all brakes, using a
brake tester or by driving the vehicle for a short dis-
tance on a straight road.
2. BRAKE SERVO SYSTEM
1) With the engine off, depress the brake pedal
several times applying the same pedal force: Make
sure the travel distance should not change.
2) With the brake pedal depressed, start the en-
gine: Make sure the pedal should move slightly to-
ward the floor.
3) With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds:
Make sure the pedal height should not change.
4) Check valve is built into the vacuum hose. Dis-
connect the vacuum hose to inspect function of
check valve.
Blow air into the vacuum hose from its brake boost-
er side end: Air must flow out of engine side end of
hose. Next blow air into the hose from engine side:
Air should not to brake booster side.
Replace both check valve and vacuum hose if the
check valve is faulty. Engine side of vacuum hose
is indicated by marking “ENG” as shown in illustra-
tion.
5) Check the vacuum hose for cracks or other dam-
age.
CAUTION:
When installing the vacuum hose on the engine
and brake booster, do not use soapy water or
lubricating oil on their connections.
6) Check vacuum hose to make sure it is tight and
secure.

Brake Fluid
19.Brake Fluid
A: REPLACEMENT
1) Lift-up the vehicle.
2) Remove both front and rear wheels.
3) Draw out the brake fluid from master cylinder
with syringe.
4) Refill the reservoir tank with recommended
brake fluid.
Recommended brake fluid:
FMVSS No. 116, fresh DOT3 or DOT4 brake
fluid
CAUTION:
 Avoid mixing different brands of brake fluid
to prevent degrading the quality of the fluid.
 Be careful not to allow dirt or dust to get into
the reservoir tank.
Bleeding sequence (1) → (2) → (3) → (4)
5) Install one end of a vinyl tube onto the air bleeder
and insert the other end of the tube into a container
to collect the brake fluid.
CAUTION:
 Cover the bleeder with waste cloth, when
loosening it, to prevent brake fluid from being
splashed over surrounding parts. During the bleeding operation, keep the
brake reservoir tank filled with brake fluid to
eliminate entry of air.
 The brake pedal operating must be very slow.
 For convenience and safety, two people
should do the work.
NOTE:
The amount of brake fluid required is approx. 500
m2 (16.9 US fl oz, 17.6 Imp fl oz) for total brake
system.
6) Instruct your co-worker to depress the brake
pedal slowly two or three times and then hold it de-
pressed.
7) Loosen the bleeder screw approx. 1/4 turn until a
small amount of brake fluid drains into container,
and then quickly tighten the screw.
8) Repeat steps 6) and 7) above until there are no
air bubbles in the drained brake fluid and new fluid
flows through vinyl tube.
NOTE:
Add brake fluid as necessary while performing the
air bleed operation, in order to prevent the tank
from running short of brake fluid.
9) After completing the bleeding operation, hold
brake pedal depressed and tighten the bleeder
screw and install bleeder cap.
Tightening torque:
8 N·m (0.8 kgf-m, 5.8 ft-lb)
10) Bleed air from each wheel cylinder by following
the previous 5 steps.
11) Depress the brake pedal with a force of approx.
294 N (30 kgf, 66 lb) and hold it there for approx. 20
seconds. At this time check the pedal to see if it
makes any unusual movement. Visually inspect the
bleeder screws and brake pipe joints to make sure
that there is no fluid leakage.
12) Install the wheels, and drive the vehicle for a
short distance between 2 to 3 km (1 to 2 miles) to
make sure that brakes are operating properly.
