Engine oil

CAUTION

.

If the level gauge cannot be

pulled out easily, twist the level
gauge right and left, then gently
pull it out. Otherwise, you may be
injured accidentally straining
yourself.

.

Use only engine oil with the

recommended grade and vis-
cosity.

.

Be careful not to spill engine oil

when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.

&

Engine oil consumption

Some engine oil will be consumed while
driving. The rate of consumption can be
affected by such factors as transmission
type, driving style, terrain and tempera-
ture. Under the following conditions, oil
consumption can be increased and thus
require refilling between maintenance in-
tervals:

.

When the engine is new and within the

break-in period

.

When the engine oil is of lower quality

.

When the incorrect oil viscosity is used

.

When engine braking is employed

(repeatedly)

.

When the engine is operated at high

engine speeds (for extended periods of
time)

.

When the engine is operated under

heavy loads (for extended periods of time)

.

When the engine idles for extended

periods of time

.

When the vehicle is operated in stop

and go and/or heavy traffic situations

.

When the vehicle is used under severe

thermal conditions

.

When the vehicle accelerates and

decelerates frequently

Under these or similar conditions, you
should check your oil at least every 2nd
fuel fill-up and change your engine oil more
frequently. Different drivers in the same
car may experience different results. If
your oil consumption rate is greater than
expected, contact your authorized
SUBARU retailer who may perform a test
under controlled conditions.

Approximately 1.1 US qt (1.0 liter, 0.9 Imp
qt) from low level to full level

4. Pull out the oil level gauge again.
5. Check the oil levels on both sides of the
level gauge. The engine oil level must be

judged by the lowest of the two levels. If
the oil level is below the low level mark,
add oil so that the full level is reached.

CAUTION

.

Be careful not to touch the engine

oil filter when removing the oil
filler cap. Doing so may result in a
burn, a pinched finger, or may
cause some other injury.

.

Use only engine oil with the

recommended grade and vis-
cosity.

.

Be careful not to spill engine oil

when adding it. If oil touches the
exhaust pipe, it may cause a bad
smell, smoke, and/or a fire. If
engine oil gets on the exhaust
pipe, be sure to wipe it off.

To add engine oil, remove the engine oil
filler cap and slowly pour engine oil
through the filler neck. After pouring oil
into the engine, you must use the level
gauge to confirm that the oil level is
correct.

NOTE

.

To prevent overfilling the engine oil,

do not add any additional oil above the
upper level when the engine is cold.

.

After adding or changing the engine

oil, warm up the engine and stop it on a
level surface, then start the engine after
a lapse of 1 minute or more. Confirm
that the warning light has turned off
after the engine has started. Refer to
“Engine low oil level warning light”

Changing the oil and oil filter

Change the oil and oil filter according to
the maintenance schedule in the “War-
ranty and Maintenance Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in
the maintenance schedule when driving
on dusty roads, when short trips are
frequently made, or when driving in ex-
tremely cold weather.

NOTE

.

Changing the engine oil and oil filter

should be performed by a well-trained
expert. Contact your SUBARU dealer
for changing the engine oil and oil filter.
Fully trained mechanics are on standby

Recommended grade and
viscosity

CAUTION

Use only engine oil with the recom-
mended grade and viscosity.

Refer to “Engine oil”

F

12-4.

NOTE

Engine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. However,
in hot weather, oil of higher viscosity is
required to properly lubricate the en-
gine.

&

Synthetic oil

You should use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using syn-
thetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner’s Manual. Refer to “Engine
oil”

F

12-4. Also, you must follow the oil

and filter changing intervals shown in the

Warranty and Maintenance booklet.

NOTE

Synthetic oil of the grade and viscosity
noted in chapter 12 is the recom-
mended engine oil for optimum engine
performance. Conventional oil may be
used if synthetic oil is unavailable.

Cooling system

&

Safety precautions

WARNING

Never remove the radiator cap until
the engine has been shut off and has
cooled down completely. Since the
coolant is under pressure, you may
suffer serious burns from a spray of
boiling hot coolant when the cap is
removed.

CAUTION

.

Vehicles are filled at the factory

with SUBARU SUPER COOLANT
that does not require the first
change for 11 years/137,500
miles (11 years/220,000 km). This
coolant should not be mixed with
any other brand or type of cool-
ant during this period. Mixing
with a different coolant will re-
duce the life of the coolant. When
necessary to top up the coolant
for any reason, use only SUBARU
SUPER COOLANT.

If SUBARU SUPER COOLANT is
diluted with another brand or

type, the maintenance interval is
shortened to that of the mixing
coolant.

.

Do not splash the engine coolant

over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.

&

Cooling fan, hose and con-
nections

Your vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.

Air cleaner element

WARNING

Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters in-
take air but also stops flames if the
engine backfires. If the air cleaner
element is not installed when the
engine backfires, you could be
burned.

CAUTION

When replacing the air cleaner ele-
ment, use a genuine SUBARU air
cleaner element. If it is not used,
there is the possibility of causing a
negative effect to the engine.

Tires and wheels

&

Types of tires

You should be familiar with type of tires
present on your vehicle.

!

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

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 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 inflation pressure label. Specifi-
cally, inflate them by an extra 1 psi (6.9
kPa, 0.07 kgf/cm

2

) for every difference of

10

8

F (5.6

8

C) 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 outside tempera-
tures when the temperature in the garage
is 60

Example:

Tire size: P205/55R16 89V, 205/50R17

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

(416,1)

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 of
the 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.

To register newly fitted TPMS valves on
the replacement wheels (when switching
to snow tires, for example), drive for
several minutes at a speed of 25 mph (40
km/h) or higher.

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.

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 soon as possi-
ble.

If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Other-
wise an accident involving serious
vehicle damage and serious perso-
nal injury could occur.

1) Keep driving straight ahead while

gradually reducing speed.

2) Slowly pull off the road to a safe

place.

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 air 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 possible
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.

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 im-
mediately if you find any problem.
