Operating tips for heater and air conditionerCleaning ventilator grille
HB5019BC
Always keep the front ventilator inlet grille free of snow, leaves, or oth-
er obstructions to ensure efficient heating and defrosting. Since the
condenser is located in front of the radiator, this area should be kept
clean because cooling performance is impaired by any accumulation
of insects and leaves on the condenser. Efficient cooling after parking in direct sunlight
After parking in direct sunlight, drive with the windows open for a few
minutes to allow outside air to circulate into the heated interior. This
results in quicker cooling by the air conditioner. Keep the windowsclosed during the operation of the air conditioner for maximum cool-
ing efficiency. Lubrication oil circulation in the refrigerant circuit
Operate the air conditioner compressor at a low engine speed (at idle
or low driving speeds) a few minutes each month during the off-sea-
son to circulate its oil. Checking air conditioning system before summer season
Check the air conditioner unit for refrigerant leaks, hose conditions,
and proper operation each spring. This check is best performed by
your SUBARU dealer.

Engine overheatingWARNING
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 engineis still hot could release a spray of boiling hot coolant, which
could burn you very seriously.
If the engine overheats, safely pull off the road and stop the vehicle in asafe place. If steam is coming from the engine compartment
Turn the engine off and get everyone away from the vehicle until itcools down. If no steam is coming from the engine compartment
1. Keep the engine running at idling speed.
2. Open the hood to ventilate the engine compartment.
Confirm that the cooling fan is turning. If the fan is not turning, im-
mediately turn the engine off and contact your authorized dealer for
repair.
3. After the engine coolant temperature has dropped, turn off the en-gine.
If the temperature gauge stays at the overheated zone, turn the en-
gine off.
4. After the engine has fully cooled down, check the coolant level in
the reserve tank.If the coolant level is below the “MIN” mark, add coolant up to the
“MAX” mark.
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 counterclockwise
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.
Towing
WARNING
Never tow AWD vehicles (both AT and MT) with the front wheelsraised off the ground while the rear wheels are on the ground, orwith the rear wheels raised off the ground while the front wheelsare on the ground. This will cause the vehicle to spin away due tothe operation or deterioration of the center differential.
HG9013BA
If towing is necessary, it is best done by your SUBARU dealer or a com-
mercial towing service. Observe the following procedures for safety.
Towing and tie-down hooks
CAUTION
Use only specified towing hooks and tie-down hooks. Never
use suspension parts or other body parts for towing or tie-downpurposes. Never use the tie-down hook closest to the muffler under the
vehicle for towing purposes. Do not apply excessive lateral load to the towing hooks.

Cooling systemWARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
CAUTION
The cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-around coolant which providesprotection against freezing down to –33°F ( –36 °C). For adding,
use genuine SUBARU coolant or an equivalent: a mixture of 50%
soft water and 50% ethylene-glycol basis coolant. Use of improp-er coolants may result in corrosion in the cooling system. It is im-portant to maintain protection against freezing and corrosion,even if freezing temperatures are not expected. Never mix differ-ent kinds of coolant. Do not splash the engine coolant over painted parts. The alco-
hol contained in the engine coolant may damage the paint sur-face.
Hose and connections
Your vehicle employs an electric cooling fan which is thermostatically
controlled to operate when the engine coolant reaches a specific tem-
perature.If the radiator cooling fan does not operate even when the engine
coolant temperature gauge exceeds the normal operating range, the
cooling fan circuit may be defective. Check the fuse and replace it if
necessary. 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 cooling system. It is recommended that the cooling systemand connections be checked for leaks, damage, or looseness.

Engine coolant Checking the coolant level
Check the coolant level at each fuel stop.
HBB004FB
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, re-
move the radiator cap and refill as required.

Rubber gaskets
3. After refilling the reserve tank and the radiator, reinstall the caps
and check that the rubber gaskets inside the radiator cap are in the
proper position.

Changing the coolant
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
Change the engine coolant using the following procedures according
to the maintenance schedule in the “Warranty and Maintenance Book-
let”. 1. Remove the under cover.
2. Place a proper container under the drain plug and loosen the drainplug.
HBB059BB

3. Loosen the radiator cap to drain the coolant from the radiator. Then
drain the coolant from the reserve tank. Tighten the drain plug secure-
ly.

4. Slowly pour the coolant and fill to the radiator filler neck and to the
reserve tank ’s “FULL” level mark. Do not pour the coolant too quickly,
as this may lead to insufficient air bleeding and trapped air in the sys-tem.

Rubber gaskets
5. Put the radiator cap back on and tighten firmly. At this time, make
sure that the rubber gasket in the radiator cap is correctly in place.
6. Start and run the engine for more than five minutes at 2,000 to
3,000 rpm.

7. Stop the engine and wait until the coolant cools down (122 to 140°F [50 to 60 °C]). If there is any loss of coolant, add coolant to the
radiator’ s filler neck and to the reserve tank ’s “FULL” level.
8. Put the radiator cap and reservoir cap back on and tighten firmly.
Air cleaner element
WARNING
Do not operate the engine with the air cleaner element removed.The air cleaner element not only filters intake 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.
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.
The air cleaner element is a viscous type. It is unnecessary to clean or wash the element. Replacing the air cleaner element
Replace the air cleaner element according to the maintenance sched-ule in the “Warranty and Maintenance Booklet ”. Under extremely
dusty conditions, replace it more frequently. It is recommended that
you always use genuine SUBARU parts.
