Engine overheating
WARNING
Never attempt to remove the radiator
cap until the engine has been shut
off and has fully cooled down. When
the engine is hot, the coolant is
under pressure. Removing the cap
while the engine is still hot could
release a spray of boiling hot cool-
ant, which could burn you very
seriously.
If the engine overheats, safely pull off the
road and stop the vehicle in a safe
location.&If steam is coming from the
engine compartment.Turn the ignition switch to the“LOCK”/
“OFF”position and get everyone away
from the vehicle until it cools down.
.Contact an authorized SUBARU deal-
er.&If no steam is coming from the
engine compartment1. Keep the engine running at idling
speed.2. Open the engine hood to ventilate the
engine compartment. Refer to“Engine
hood”F11-5.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact an authorized
SUBARU dealer for repair.
3. After the coolant temperature high
warning light that has blinked or illumi-
nated inREDturns off, turn off the engine.
For details about the warning light, refer to
“Coolant temperature low indicator light/
Coolant temperature high warning light”
F3-16.
4. After the engine has fully cooled down,
check the coolant level in the reserve tank.
If the coolant level is below the“LOW”
mark, add coolant up to the“FULL”mark.
NOTEFor details about how to check the
coolant level or how to add coolant,
refer to“Engine coolant”F11-11.
5. If there is no coolant in the reserve
tank, add coolant to the reserve tank. Then
remove the radiator cap and fill the radiator
with coolant.
If you remove the radiator cap from a hot
radiator, first wrap a thick cloth around the
radiator cap, then turn the cap counter-
clockwise slowly without pressing downuntil it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it.

ter for this wiring. If your SRS
airbag or seatbelt pretensioner
needs service, consult your near-
est SUBARU dealer.
NOTESUBARU does not endorse the use of
non-SUBARU approved flushing sys-
tems and strongly advises against
performing these services on a
SUBARU vehicle. Non-SUBARU ap-
proved flushing systems use chemi-
cals and/or solvents which have not
been tested or approved by SUBARU.
SUBARU warranties do not cover any
part of the vehicle which is damaged by
adding or applying chemicals and/or
solvents other than those approved or
recommended by SUBARU.&Before checking or servicing
in the engine compartment
WARNING
.Always stop the engine and apply
the parking brake firmly to pre-
vent the vehicle from moving.
.Always let the engine cool down.
Engine parts become very hotwhen the engine is running and
remain hot for some time after the
engine has stopped.
.Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
.When the ignition switch is in the
“ON”position, the cooling fan
may operate suddenly even when
the engine is stopped. If your
body or clothes come into con-
tact with a rotating fan, that could
result in serious injury. To avoid
risk of injury, perform the follow-
ing precautions.
–Models with push-button start
system:
Always turn the push-button
ignition switch to the“OFF”
position and confirm that the
operation indicator on the
switch is turned off. Then take
the access key fob out from
the vehicle.
–Models without push-button
start system:
Always remove the key from
the ignition switch.
.Before performing any servicing
on a vehicle equipped with aremote engine start system (a
dealer option), temporarily place
the remote engine start system in
service mode to prevent it from
unexpectedly starting the engine.
&When checking or servicing
in the engine compartment
CAUTION
.Do not contact the drive belt
cover while checking the compo-
nents in the engine compartment.
Doing so may cause your hand to
slip off the cover and result in an
unexpected injury.

self, observe the local regulations and
dispose of waste oil properly.&Recommended grade and
viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Refer to“Engine oil”F12-4.NOTEEngine 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 oilYou 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”F12-4. 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.
Cooling system&Safety precautions
WARNING
Never attempt to 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. Should it be
necessary to top up 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.
&Cooling fan, hose and con-
nectionsYour vehicle employs an electric cooling
fan which is thermostatically controlled to
operate when the engine coolant reaches
a specific temperature.
If the radiator cooling fan does not operate
even when the coolant temperature high
warning light blinks or illuminates inRED,
the cooling fan circuit may be defective.
Refer to“Coolant temperature low indica-
tor light/Coolant temperature high warning
light”F3-16.
Check the fuse and replace it if necessary.
Refer to“Fuses”F11-34 and“Fuse panel
located in the engine compartment”F12-
12.
If the fuse is not blown, have the cooling
system checked by your SUBARU dealer.
If frequent addition of coolant is necessary,
there may be a leak in the engine coolingsystem. It is recommended that the cooling
system and connections be checked for
leaks, damage, or looseness.
&Engine coolant!Checking the coolant level
WARNING
Never attempt to 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.
1)“FULL”level mark
2)“LOW”level markCheck the coolant level at each fuel stop.
1. Check the coolant level on the outside
of the reservoir while the engine is cool.
2. If the level is close to or lower than the
“LOW”level mark, add coolant up to the
“FULL”level mark. If the reserve tank is
empty, remove the radiator cap and refill
coolant up to just below the filler neck as
shown in the following illustration.

1) Fill up to this level3. After refilling the reserve tank and the
radiator, reinstall the cap and check that
the rubber gaskets inside the radiator cap
are in the proper position.
CAUTION
.Be careful not to spill engine
coolant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on
the exhaust pipe, be sure to wipe
it off.
.Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
!Changing the coolant
It may be difficult to change the coolant.
Have the coolant changed by your
SUBARU dealer if necessary.
The coolant should be changed according
to the maintenance schedule in the“War-
ranty and Maintenance Booklet”.
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.
The air cleaner element functions as a filter
screen. When the element is perforated or
removed, engine wear will be excessive
and engine life shortened.
It is not necessary to clean or wash the air
cleaner element.

&Windshield washer fluidUse 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. SUBARU Windshield Washer Fluid
contains 58.5% methyl alcohol and 41.5%
surfactant, by volume. Its freezing tem-
perature varies according to how much it is
diluted, as indicated in the following table.

In order to prevent freezing of washer fluid,
check the freezing temperatures in the
table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside
temperature, it may freeze and block the
