Power steering fluid &Checking the fluid level
WARNING
Be careful not to burn yourself
because the fluid may be hot.
CAUTION
. When power steering fluid is
being added, use only clean fluid,
and be careful not to allow any
dirt into the tank. And never use
different brands together.
. Avoid spilling fluid when adding
it in the tank. .
Be careful not to spill power
steering fluid when adding it. If
power steering fluid touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
power steering fluid gets on the
exhaust pipe, be sure to wipe itoff.
The power steering fluid expands greatly
as its temperature rises; the fluid level
differs according to fluid temperature.
Therefore, the reservoir tank has two
different checking ranges for hot and coldfluids.
Check the power steering fluid level
monthly.
1. Park the vehicle on a level surface,
and stop the engine.
2. Check the fluid level of the reservoir tank.
When the fluid is hot after the vehicle has
been run: Check that the oil level isbetween “HOT MIN ”and “HOT MAX ”on
the surface of the reservoir tank.
When the fluid is cool before the vehicle is
run: Check that the oil level is between“ COLD MIN ”and “COLD MAX ”on the
surface of the reservoir tank.
3. If the fluid level is lower than the
applicable “MIN ”line, add the recom- mended fluid as necessary to bring the
level between the
“MIN ”and “MAX ”line.
If the fluid level is extreme low, it may
indicate possible leakage. Consult your
SUBARU dealer for inspection.
& Recommended fluid
Use one of the following types of auto-
matic transmission fluid. Genuine Subaru Automatic Transmis-
sion Fluid Type-HP “Dexron III ”Type Automatic Transmis-
sion Fluid

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.Brake pedal

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
Page 379 of 444

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 moretimes. ! Parking brake lining
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
certain to pull the lever up slowly
and gently. 1. Drive the vehicle at a speed of
approximately 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 lbs [147 N, 15kg].)
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: 5–6 notches / 44 lbs (196 N, 20 kg) Parking brake stroke
Check the parking brake stroke according
to the maintenance schedule in the“
Warranty and Maintenance Booklet ”.
When the parking brake is properly
adjusted, braking power is fully applied
by pulling the lever up five to six notches
gently but firmly (approximately 44 lbs,
196 N, 20 kg). If the parking brake lever
stroke is not within the specified range,
have the brake system checked and
adjusted at your SUBARU dealer. Maintenance and service

Tires and wheels &Types of tires
You should be familiar with type of tires
present on your vehicle. ! All season tires
The factory-installed tires on your new
vehicle except 2.5GT spec.B are all
season tires.
All season tires are designed to provide
an adequate measure of traction, handling
and braking performance in year-round
driving including snowy and icy road
conditions. However all season tires do
not offer as much traction performance as
winter (snow) tires in heavy or loose snow
or on icy roads.
All season tires are identified by “ALL
SEASON ”and/or “M+S ”(Mud & Snow) on
the tire sidewall. ! Summer tires
The factory-installed tires on your new
2.5GT spec.B vehicle are summer tires.
Summer tires are high-speed capability
tires best suited for highway driving under
dry conditions.
Summer tires are inadequate for driving
on slippery roads such as on snow-
covered or icy roads.
If you drive your vehicle on snow-covered or icy roads, we strongly recommend the
use of winter (snow) tires.
When installing winter tires, be sure to
replace all four tires. !
Winter (snow) tires
Winter tires are best suited for driving on
snow-covered and icy roads. However
winter tires do not perform as well as
summer tires and all season tires on roads
other than snow-covered and icy roads.
& Tire pressure monitoring
system (TPMS) (if equipped)
The tire pressure monitoring system pro-
vides the driver with a warning message
by sending a signal from a sensor that is
installed in each wheel when tire pressure
is severely low. The tire pressure monitor-
ing system will activate only when the
vehicle is driven. Also, this system may
not react immediately to a sudden drop in
tire pressure (for example, a blow-out
caused by running over a sharp object).
If 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 come on. 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/cm2) for
every difference of 10 8F (5.6 8C) 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 60 8F (15.6 8C).
Example:
Tire size: P225/55R17 95V, P225/60R16 97H
Standard tire pressures:
Front: 32 psi (220 kPa, 2.2 kgf/cm
