2010 SUBARU LEGACY coolant temperature

7-18Starting and operating
Automatic transmission/Con-
tinuously variable transmis-sion
The automatic transmission is electroni-
cally controlled and provides 5 forward
speeds and 1 reverse speed. The con-
tinuously variable transmission is electro-
nically controlled and provides an infinite
number of forward speeds and 1 reversespeed.
Both the automatic transmission and
continuously variable transmission have
a manual mode.
WARNING
Do not shift from the “P ” or “N ”
position into the “D ” or “R ” position
while depressing the accelerator
pedal. This may cause the vehicle
to jump forward or backward.
CAUTION
. Shift into the “P ” or “R ” position
only after the vehicle is comple-
tely stopped. Shifting while the
vehicle is moving may cause
damage to the transmission.
. Do not race the engine for more than 5 seconds in any position
except the
“N ” or “P ” position
when the brake is applied or
when chocks are used in the
wheels. This may cause the
transmission fluid to overheat.
. Avoid shifting from one of the
forward driving positions into the“ R ” position or vice versa until
the vehicle has completely
stopped. Such shifting may
cause damage to the transmis-sion.
. When parking the vehicle, first
securely apply the parking brake
and then place the select lever inthe “P ” position. Avoid parking
for a long time with the select
lever in any other position as
doing so could result in a dead
battery.
NOTE . For AT models, when the engine
coolant temperature is still low, the
transmission will upshift to higher
engine speeds than when the coolant
temperature is sufficiently high in order
to shorten the warm-up time and
improve driveability. The gearshift tim-
ing will automatically shift to the nor- mal timing after the engine has warmedup..
Immediately after transmission fluid
is replaced, you may feel that the
transmission operation is somewhat
unusual. This results from invalidation
of data which the on-board computer
has collected and stored in memory to
allow the transmission to shift at the
most appropriate times for the current
condition of your vehicle. Optimized
shifting will be restored as the vehicle
continues to be driven for a while.. When driving a vehicle that is
equipped with CVT under continuous
heavy load conditions such as towing a
camper or climbing a long, steep hill,
the engine speed or the vehicle speed
may automatically be reduced. This is
not a malfunction. This phenomenon
results from the engine control func-
tion maintaining the cooling perfor-
mance of the vehicle. The engine and
vehicle speed will return to a normal
speed when the engine is able to
maintain the optimum cooling perfor-
mance after the heavy load decreases.
Driving under a heavy load must be
performed with extreme care. Do not
try to pass a vehicle in front when
driving on an uphill slope while towing.. The continuously variable transmis-
sion is a chain type system 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

&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

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 followingtable.Washer Fluid
Concentration Freezing
Temperature
30% 10.48F( 12 8C)
50% 48F( 20 8C)
100% 49 8F( 45 8C)
CAUTION
Never use engine coolant as washer
fluid because it could cause paintdamage.
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. Replacement of wiper blades
Grease, wax, insects, or other materials
on the windshield or the wiper blade
results in jerky wiper operation and streak-
ing on the glass. If you cannot remove the
streaks after operating the windshield
washer or if the wiper operation is jerky,
clean the outer surface of the windshield
(or rear window) and the wiper blades
using a sponge or soft cloth with a neutral
detergent or mild-abrasive cleaner. After
cleaning, rinse the windshield and wiper
blades with clean water. The windshield is
clean if beads do not form when you rinse
the windshield with water.
CAUTION
. Do not clean the wiper blades
with gasoline or a solvent, such
as paint thinner or benzine. This
will cause deterioration of the
wiper blades.
. When you wish to raise the
passenger-side wiper arm, first
raise the driver-side wiper arm.
Otherwise, the passenger-side
wiper assembly and driver-side
wiper assembly will touch each
other, possibly resulting inscratches. Maintenance and service
