2010 SUBARU LEGACY coolant

7-8Starting and operating
NOTE
Engine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops. Starting the engine &
MT models
1. Apply the parking brake.
2. Turn off unnecessary lights and ac- cessories.
3. Depress the clutch pedal to the floor
and shift the shift lever into neutral. Hold
the clutch pedal to the floor while starting
the engine. The starter motor will only
operate when the clutch pedal is de-
pressed fully to the floor.
4. Turn the ignition switch to the “ON ”
position and check the operation of the
warning and indicator lights. Refer to“ Warning and indicator lights ”F 3-9.
CAUTION
Do not operate the starter motor
continuously for more than 10 sec-
onds. If the engine fails to start after
operating the starter for 5 to 10
seconds, wait for 10 seconds or
more before trying again.
5. Turn the ignition switch to the “START ”
position without depressing the accelera-
tor pedal. Release the key immediately
after the engine has started.
If the engine does not start, perform the
following procedure. (1) Turn the ignition switch to the“
LOCK ”position and wait for at least
10 seconds. After checking that the
parking brake is firmly applied, turn the
ignition switch to the “START ”position
while depressing the accelerator pedal
slightly (approximately a quarter of the
full stroke). Release the accelerator
pedal as soon as the engine starts.
(2) If this fails to start the engine, turn
the ignition switch back to the “LOCK ”
position and wait for at least 10
seconds. Then fully depress the accel-
erator pedal and turn the ignition
switch to the “START ”position. If the
engine starts, quickly release the
accelerator pedal.
(3) If this does not start the engine,
turn the ignition switch again to the“ LOCK ”position. After waiting for 10
seconds or longer, turn the ignition
switch to the “START ”position without
depressing the accelerator pedal.
(4) If the engine still refuses to start,
contact your nearest SUBARU dealer
for assistance.

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

11-4Maintenance and service
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly
wash them out with clean water.
. Do not tamper with the wiring of
the SRS airbag system or seat-
belt pretensioner system, or at-
tempt to take its connectors
apart, as that may activate the
system or it can render it inop-
erative. NEVER use a circuit
tester for these wiring. If your
SRS airbag or seatbelt preten-
sioner needs service, consult
your nearest SUBARU dealer. &
Before checking or servicing
in the engine compartment
WARNING
. Always stop the engine and set
the parking brake firmly to pre-
vent the vehicle from moving.
. Always let the engine cool down.
Engine parts become very hot
when the engine is running and
remain hot for some time after
the engine is stopped.
. Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
. Always remove the key from the
ignition switch. When the ignition
switch is in the “ON ”position,
thecoolingfanmayoperate
suddenly even when the engine
is stopped.
. Before performing any servicing
on a vehicle equipped with a
remote engine start system tem-
porarily place that system in the
service mode to prevent it from
unexpectedly starting the engine. &
When checking or servicing
in the engine compartment
(2.5 L non-turbo models)
CAUTION
Do not contact the belt cover while
checking the components in the
engine compartment. Doing so may
cause your hand to slip off the belt
cover and result in an unexpected
injury.
