2010 SUBARU LEGACY oil temperature

8-8Driving tips
Winter driving
&Operation during cold weather
Carry some emergency equipment, such
as a window scraper, a bag of sand,
flares, a small shovel and jumper cables.
Check the battery and cables. Cold
temperatures reduce battery capacity.
The battery must be in good condition to
provide enough power for cold winterstarts.
Use an engine oil of proper grade and
viscosity for cold weather. Heavy summer
oil will cause harder starting.
Keep the door locks from freezing by
squirting them with deicer or glycerin. Forcing a frozen door open may damage
or separate the rubber weather strips
around the door. If the door is frozen,
use hot water to melt the ice, and after-
wards thoroughly wipe the water away.
Use a windshield washer fluid that con-
tains an antifreeze solution. Do not use
engine antifreeze or other substitutes
because they may damage the paint of
the vehicle.
SUBARU Windshield Washer Fluid con-
tains 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 followingtable.
Washer Fluid Con- centration Freezing Temperature
30% 10.4 8F( 12 8C)
50% 48F( 20 8C)
100%
49 8F( 45 8C)
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 thenozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.
! Before driving your vehicle
Before entering the vehicle, remove any
snow or ice from your shoes because that

engine braking effect and prevent over-
heating of your vehicle ’s brakes. Do not
make sudden downshifts. . When driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. . When driving uphill in hot weather, pay
attention to the coolant temperature high
warning light (for all models) and AT OIL
TEMP warning light (for AT and CVT
models) because the engine and trans-
mission are relatively prone to overheating
under these conditions. If the coolant
temperature high warning light and/or the
AT OIL TEMP warning light illuminates,
immediately turn off the air conditioner and
stop the vehicle in the nearest safe
location. For further instructions and addi-
tional information, refer to the followingsections.
–“If you park your vehicle in an
emergency ”F 9-2
–“ Engine overheating ”F 9-12
–“ Coolant temperature low indicator
light/Coolant temperature high warn-
ing light ”F 3-13 –“
AT OIL TEMP warning light (AT and
CVT models) ”F 3-15
. For AT and CVT models, avoid using
the accelerator pedal to stay stationary on
an uphill slope instead of using the
parking brake or foot brake. That may
cause the transmission fluid to overheat. ! Parking on a grade
Always block the wheels under both
vehicle and trailer when parking. Apply
the parking brake firmly. You should not
park on a hill or slope. But if parking on a
hill or slope cannot be avoided, you
should take the following steps:
1. Apply the brakes and hold the pedal down.
2. Have someone place wheel blocks
under both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then
apply the parking brake; slowly release
the regular brakes.
5. Shift into 1st or reverse gear (MT
models) or “P ” (AT and CVT models) and
shut off the engine.

9-12In case of emergency
Engine overheating
WARNING
Never attempt to remove the radia-
tor 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
coolant, which could burn you very
seriously.
If the engine overheats, pull off the road
safely and stop the vehicle in a safe place.
& If steam is coming from the
engine compartment
Turn off the engine and get everyone
away from the vehicle until it cools down. & If no steam is coming from
the engine compartment
For details about how to check the coolant
level or how to add coolant, refer to“ Engine coolant ”F 11-18.
1. Keep the engine running at idlingspeed.
2. Open the hood to ventilate the engine compartment. Refer to
“Engine hood ”
F 11-7.
Confirm that the cooling fan is turning. If
the fan is not turning, immediately turn off
the engine and contact your authorized
dealer for repair.
3. After the engine coolant temperature
has dropped, turn off the engine.
If the coolant temperature high warning
light illuminates, turn off the engine.
4. After the engine has fully cooled down,
check the coolant level in the reservetank.
If the coolant level is below the “MIN ”
mark, add coolant up to the “MAX ”mark.
Refer to “Engine coolant ”F11 - 1 8 f o r
details.
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 down
until it stops. Release the pressure from
the radiator. After the pressure has been
fully released, remove the cap by pressing
down and turning it. TowingWARNING
Never tow AWD vehicles (including
AT, MT and CVT) with the front
wheels raised off the ground while
the rear wheels are on the ground,
or with the rear wheels raised off the
ground while the front wheels are on
the ground. This will cause the
vehicle to spin away due to the
operation or deterioration of the
center differential.
If towing is necessary, it is best done by
your SUBARU dealer or a commercial
towing service. Observe the following

2.5 L turbo models
3.6 L models
6. Remove the oil filter with an oil filter wrench.
7. Before installing a new oil filter, apply a
thin coat of engine oil to the seal. 8. Clean the rubber seal seating area of
the bottom of engine and install the oil
filter by hand turning. Be careful not to
twist or damage the seal.
9. Tighten the oil filter by the amount
indicated in the following table after the
seal makes contact with the bottom ofengine.
Model Oil filter
color Part
number Amount of
rotation
2.5 L models Black 15208AA100 1 rotation
Blue 15208AA12A 7/8
rotation
3.6 L models Black 15208AA031 3/4
rotation
CAUTION
. Never over tighten the oil filter
because that can result in an oil leak.
. Thoroughly wipe off any engine
oil that has spilled over the
exhaust pipe and/or under-cover.
If left unremoved, the oil could
catch fire.
10. Reinstall the cover under the oil filter.
11. Pour engine oil through the filler neck. Oil capacity (guideline):
2.5 L models: 4.2 US qt (4.0 liters, 3.5 Imp qt)
3.6 L models: 6.7 US qt (6.3 liters, 5.5 Imp qt)
The oil quantity indicated above is only a
guideline. The necessary quantity of oil
depends on the quantity of oil that has
been drained. The quantity of drained oil
differs slightly depending on the tempera-
ture of the oil and the time the oil is left
flowing out. After refilling the engine with
oil, therefore, you must use the level
gauge to confirm that the level is correct.
12. Start the engine and make sure that no
oil leaks appear around the filter ’s rubber
seal and drain plug.
13. Keep the engine idling until the engine
reaches the normal operating temperature
range, as indicated by the temperature
gauge on the combination meter. After
that, check the engine oil level again. For
further details about the check procedure,
refer to “Checking the oil level ”F 11-12.

&Recommended grade and viscosity
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
Oil grade: –ILSAC GF-4, which can be identified
with the ILSAC certification mark (Star-
burst mark) – or API classification SM with the words
“ ENERGY CONSERVING ”
These recommended oil grades can be
identified by looking for either or both of
the following marks displayed on the oil
container.
ILSAC Certification Mark (Starburst Mark)
API Service label
1) Indicates the oil quality by API designa- tions
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving capabilities In choosing an oil, you want the proper
quality and viscosity, as well as one that
will add to fuel economy. The following
table lists the recommended viscosities
and applicable temperatures.
When adding oil, different brands may be
used together as long as they are the
same API classification and SAE viscosity
as those recommended by SUBARU.
SAE viscosity numb
er and applicable
temperature
*: 5W-30 is preferred.
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 engine.

&Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in
areas with very high temperatures, or
used for heavy-duty applications such as
towing a trailer, use of oil with the following
grade and viscosities is recommended.
API classification SM or SL: SAE viscosity No.:30, 40, 10W-50, 20W-40, 20W-50 Cooling system
WARNING
Never attempt to remove the radia-
tor 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 boil-
ing hot coolant when the cap isremoved.
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 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 mixingcoolant.
. 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.
If the radiator cooling fan does not operate
even when the coolant temperature high
warning light illuminates, the cooling fan
circuit may be defective. Check the fuse
and replace it if necessary. Refer to“ Fuses ”F 11-48 and “Fuses and circuits ”
F 12-6. If the fuse is not blown, have the
cooling system checked by your SUBARU
dealer.
If frequent addition of coolant is neces-
sary, there may be a leak in the engine
cooling system. It is recommended that
the cooling system and connections be
checked for leaks, damage, or looseness. Maintenance and service

1) Upper level
2) Lower level
3. Pull out the level gauge again and
check the oil level on it. If it is below the
lower level, add oil through the level
gauge hole to bring the level up to the
upper level.
CAUTION
Be careful not to spill manual trans-
mission oil when adding it. If oil
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or a
fire. If oil gets on the exhaust pipe,
be sure to wipe it off. &
Recommended grade and viscosity
Each oil manufacturer has its own base
oils and additives. Never use different
brands together.
Oil grade: API classification GL-5SAE viscosity No. and applicable tempera- ture Automatic transmission fluid &
Checking the fluid level
The automatic transmission fluid expands
largely as its temperature rises; the fluid
level differs according to fluid temperature.
Therefore, there are two different scales
for checking the level of hot fluid and cold
fluid on the level gauge.
Though the fluid level can be checked
without warming up the fluid on the“ COLD ”range, we recommend checking
the fluid level when the fluid is at operatingtemperature. ! Checking the fluid level when the
fluid is hot
Check the fluid level monthly.
1. Drive the vehicle several miles to raise
the temperature of the transmission fluid
up to normal operating temperature; 158
to 176 8F (70 to 80 8C) is normal.
2. Park the vehicle on a level surface and
set the parking brake.
3. First shift the select lever in each
position. Then shift it in the “P ” position,
and run the engine at idling speed.
