Seatbelt Pretensioners
44Inspect the seatbelts and attachments
including the webbing and all hardware
periodically for cracks, cuts, gashes,
tears, damage, loose bolts or worn areas.
Replace the seatbelts even if only minor
damage is found.
1-5. Seatbelt PretensionersThe following seatbelts have a seatbelt
pretensioner.
 Driver’s seatbelt
 Front passenger’s seatbelt
The seatbelt preten sioners are designed
to be activated in the event of an accident
involving a moderate to severe frontal and
side collision and rollover accident.
NOTE Seatbelt pretensioners are not
designed to activate in minor impacts
or in rear impacts.
 Pretensioners are designed to func-
tion on a one-time-o nly basis. In the
event that a pretensioner is activated,
both the driver’s and front passenger’s
seatbelt retractor assemblies should
be replaced only by an authorized
SUBARU dealer. When replacing
seatbelt retractor assemblies, use only
genuine SUBARU parts.
 If a seatbelt that has a seatbelt
pretensioner does not retract or cannot
be pulled out due to a malfunction or
activation of the pretensioner, contact
your SUBARU dealer as soon as
possible.
 If the seatbelt retractor assembly or
surrounding area has been damaged,
contact your SUBARU dealer as soon
as possible.
CAUTION
 Keep the belts free of polishes,
oils, chemicals and particularly
battery acid. Never attempt to make modifica-
tions or changes that will prevent
the seatbelt from operating prop-
erly.
WARNING
 To obtain maximum protection,
the occupants should sit in an
upright position with their
seatbelts properly fastened.
Refer to "Seatbelts" P39. Do not modify, remove or strike
the seatbelt retractor assemblies
equipped with seatbelt
pretensioners or surrounding
area. This could result in acci-
dental activation of the seatbelt
pretensioners or could make the
system inoperative, possibly
resulting in serious injury. Seat-
belt pretensioners have no user-
serviceable parts. For required
servicing of seatbelt retractors
equipped with seatbelt
pretensioners, consult your
SUBARU dealer.
 When discarding seatbelt
retractor assemblies equipped

This coolant temperature low indicator
light/coolant temper ature high warning
light has the following three functions.
 Illumination in BLUE indicates insuffi-
cient warming up of the engine
 Blinking in RED indicates that the
engine is close to overheating
 Illumination in RED indicates over-
heating condition of the engine
For the system check, this indicator light/
warning light illuminates in RED for
approximately 2 seconds when the igni-
tion switch is turned to the “ON” position.
After that, this indicator light/warning light
changes to BLUE and maintains illumina- tion in
BLUE. This BLUE illuminated light
turns off when the engine is warmed up
sufficiently.
If the engine coolant temperature
increases over the specified range, the
indicator light/warning light blinks in RED.
At this time, the engine is close to over-
heating.
If the engine coolant temperature
increases further, the indicator light/
warning light illuminates in RED continu-
ously. At this time, the engine may be
overheating.
When the indicator light/warning light
blinks in RED or illuminates in RED, safely
stop the vehicle as soon as possible, and
refer to the emergency steps for the
engine overheating. Refer to "Engine
Overheating" P319. After that, have the

Engine Oil
34611-6. Engine Oil■Engine Oil ConsumptionSome 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 followi ng conditions, oil
consumption can be increased and thus
require refilling between maintenance
intervals:
 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.
■ Checking the Oil Level1. Park the vehicle on a level surface and
stop the engine. If you check the oil level
just after stopping the engine, wait for at least 5 minutes for the oil to drain back into

the oil pan before checking the level.
1) Oil level gauge
2) Oil filler cap
3) Oil filter2. Pull out the level gauge, wipe it clean,
and insert it again.
3. Be sure the level gauge is correctly
inserted until it stops.
CAUTION
 If the level gauge is not pulled out
easily, twist the level gauge right
and left, then pull it out. Other-
wise, you may be injured acciden-
tally straining yourself. Use only engine oil with the
recommended grade and
viscosity. 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.
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 acci-
dentally straining yourself.

1) Full level
2) Low level
3) 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. 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
full level when the engine is cold.
■ Changing the Oil and Oil
FilterChange the oil and oil filter according to
the maintenance schedule in the
“Warranty and Maintenance Booklet”.
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 at a SUBARU dealer to utilize
the special tools, spare parts and
recommended oil for this work, and
also, used oils are properly disposed
of.
 If performing oil replacement your-
self, observe the local regulations and
dispose of waste oil properly.■ Recommended Grade and
ViscosityRefer to "Engine Oil" P381.NOTEEngine oil viscosity (thickness) affects
fuel economy. Oils of lower viscosity
provide better fuel economy. How-
ever, in hot weather, oil of higher vis-
cosity is required to properly lubricate
the engine.
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.

Cooling System
348■Synthetic OilYou should use synthetic engine oil that
meets the same requirements given for
conventional engine oil. When using
synthetic oil, you must use oil of the same
classification, viscosity and grade shown
in this Owner’s Manual. Refer to "Engine
Oil" P381. Also, you must follow the oil
and filter changing intervals shown in the
Warranty and Maintenance booklet.NOTESynthetic 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.
11-7. Cooling System
■ Cooling Fan, Hose and
ConnectionsYour vehicle employs an electric cooling
fan which is thermost atically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be
defective. Refer to "Engine Coolant
Temperature Gauge"  P129.
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 coolant
during this period. Mixing with a
different coolant will reduce the
life of the coolant. When neces-
sary to top off the coolant for any
reason, use only SUBARU
SUPER COOLANT.
If the 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.

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 loos e, 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 Washer Fluid1) “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.
