2010 SUBARU LEGACY heating

Air filtration system
Your vehicle’s air conditioning system is
equipped with an air filtration system.
Replace the air filter element according
to the replacement schedule shown in the
following table. This schedule should be
followed to maintain the filter ’s dust
collection ability. Under extremely dusty
conditions, the filter should be replaced
more frequently. Have your filter checked
or replaced by your SUBARU dealer. For
replacement, use only a genuine
SUBARU air filter kit.
Replacement schedule: Every 15 months or 15,000 miles (24,000
km) whichever comes first
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter. . Reduction of the air flow through
the vents.
. Windshield gets easily fogged or
misted. NOTE
The filter can influence the air condi-
tioning, heating and defroster perfor-
mance if not properly maintained. &

Transmitter flash sequence Feature description
Flashes when button is pressed Indicates that the system is transmitting an RF signal.
Two long flashes following re-
mote start activation (transmit-
ter button is pressed two times
within 3 seconds) Indicates that the transmitter did not receive the remote start
activation confirmation from the vehicle system. The transmitter
will automatically send one additional remote start activation
attempt. This usually occurs when the operational range is at its
limit or has been exceeded.
One flash following remote
start activation (transmitter
button is pressed two times
within 3 seconds) Indicates that the engine is running via remote start. If the
transmitter is moved outside of the operating range of the
system, this sequence will timeout after the normal 15-minute
vehicle run cycle.
2 flashes every 5 seconds Indicates that the engine is running via remote start. If the
transmitter is removed outside of the operating range of the
system, this sequence will timeout after the normal 15-minute
vehicle run cycle.
3 flashes Indicates that the engine has turned off due to a remote start
system 15-minute timeout, vehicle safety parameter or normal shutdown. &
Entering the vehicle follow-
ing remote engine start shut- down
An alarm trigger may occur if the vehicle is
opened by the remote keyless entry
transmitter within a few seconds immedi-
ately following remote engine start shut-down. & Pre-heating or pre-cooling
the interior of the vehicle
Models with automatic climate control system:
After the system starts the engine, the
automatic climate control system will
activate the “FULL AUTO ”mode and heat
or cool the interior to the predetermined
median (room) temperature. No pre-
setting of controls is necessary.
Models with manual climate control system:
Before exiting the vehicle, set the tem-
perature controls to the desired setting
and operation. After the system starts the
engine, the heater or air conditioning will
activate and heat or cool the interior to
your setting. Starting and operating

place and let the engine idle until the
warning light turns off. &Driving tips
. On a road surface where there is a risk
of wheelspin (for example, a snow- or
gravel-covered road), you can pull away
from a standstill safely and easily by first
selecting the 2nd gear of the manualmode. . Always apply the foot or parking brake
when the vehicle is stopped in the “D ”or
“ R ”position.
. Always apply the parking brake when
parking your vehicle. Do not hold the
vehicle with only the transmission. . Do not keep the vehicle in a stationary
position on an uphill grade by using the “ D ”position. Use the brake instead.
. The engine may, on rare occasions,
knock when the vehicle rapidly acceler-
ates or rapidly pulls away from a standstill.
This phenomenon does not indicate afault. . A slight reduction in output torque may
occur in the models with a 2.5 L turbo or
3.6 L engine before the engine warms up. Power steering
CAUTION
Do not hold the steering wheel at the
fully locked position left or right for
more than 5 seconds. This may
damage the power steering pump.
The power steering system operates only
when the engine is running.
If you lose power steering assist because
the engine stops or the system fails to
function, you can steer but it will take
much more effort.
NOTE
Right after the engine has been started
and before it has warmed up, you may
hear a noise coming from areas adja-
cent to the power steering pump which
is located at the right-front area of the
engine compartment. This noise is
normal. It does not indicate power
steering system trouble. Braking &
Braking tips
WARNING
Never rest your foot on the brake
pedal while driving. This can cause
dangerous overheating of the
brakes and needless wear on the
brake pads and linings.
! When the brakes get wet
When driving in rain or after washing the
vehicle, the brakes may get wet. As a
result, brake stopping distance will be
longer. To dry the brakes, drive the vehicle
at a safe speed while lightly depressing
the brake pedal to heat up the brakes. ! Use of engine braking
Remember to make use of engine braking
in addition to foot braking. When descend-
ing a grade, if only the foot brake is used,
the brakes may start working improperly
because of brake fluid overheating,
caused by overheated brake pads. To
help prevent this, shift into a lower gear to
get stronger engine braking. ! Braking when a tire is punctured
Do not depress the brake pedal suddenly
when a tire is punctured. This could cause Starting and operating

tion has a malfunction, if you press the
Hill Holder switch, a chirp sounds. ! Hill Holder indicator light
When the Hill Holder function is activated,
the Hill Holder indicator light illuminates.
Refer to “Hill Holder indicator light ”F 3-19.
! Emergency brake
CAUTION
Use the emergency brake only in
case of an emergency. If the emer-
gency brake is excessively used,
the brake parts will wear down
faster or the brake may not work
sufficiently due to rear wheel brakeoverheating.
NOTE
While using the emergency brake, the
brake system warning light and the
indicator light on the parking brake
switch illuminate and a chirp sounds.
If the foot brake has a malfunction, you

8-26Driving tips
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.

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
