SAE viscosity number and applicable
temperature
*: 5W-30 is recommended.
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 ar-
eas with very high temperatures, or used
for heavy-duty applications such as tow-
ing a trailer, use of oil with the following
grade and viscosities is recommended.

Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed. yThe cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-
around coolant which provides
protection 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 ba-
sis coolant. Use of improper cool-
ants may result in corrosion in the
cooling system. It is important tomaintain protection against freez-
ing and corrosion, even if freezing
temperatures are not expected.
Never mix different kinds of cool-
ant.

Hose and connections
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 engine coolant tempera-
ture gauge exceeds the normal operating
range, the cooling fan circuit may be de-
fective. 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 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. „
Engine coolant
T Checking the coolant level
Check the coolant level at each fuel stop.
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, remove the radiator cap and refill
as required. 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.
y
Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.
B00309
yBe careful not to spill engine cool-
ant when adding it. If coolant
touches the exhaust pipe, it may
cause a bad smell, smoke, and/or
a fire. If engine coolant gets on the
exhaust pipe, be sure to wipe itoff.
y Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.

TChanging the coolant
Always add genuine Subaru cooling sys-
tem conditioner whenever the coolant is
replaced.
Change the engine coolant and add gen- uine Subaru cooling system conditioner
using the following procedures according
to the maintenance schedule in the “War-
ranty and Maintenance Booklet”.
1. Remove the under cover.
2. Place a proper container under the
drain plug and loosen the drain plug.
3. Loosen the radiator cap to drain the
coolant from the radiator. Then drain the
coolant from the reserve tank. Tighten the
drain plug securely.
4. Install the under cover.
1) Fill up to here
5. Slowly pour the coolant and fill up to
just below the filler neck, allowing enough
room to add genuine Subaru cooling sys-
tem conditioner in the radiator. Add genu-
ine Subaru cooling system conditioner un-
til the coolant level reaches the filler neck. Do not pour the coolant too quickly, as this
may lead to insufficient air bleeding and
trapped air in the system.
Coolant capacity (Guideline):

6. Pour the coolant and fill to the reservoir
tank’s “FULL” level mark.
7. Put the radiator cap back on and tight-
en firmly. At this time, make sure that the
rubber gasket in the radiator cap is cor- rectly in place.
8. Start and run the engine for more than
five minutes at 2,000 to 3,000 rpm.
9. Stop the engine and wait until the cool-
ant 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.
10.Put the radiator cap and reservoir cap
back on and tighten firmly.
Air cleaner element
The air cleaner element functions as a fil-
ter screen. When the element is perforat-
ed or removed, engine wear will be exces-
sive and engine life shortened.
The air cleaner element is a dry type. It is
unnecessary to clean or wash the ele- ment. „ Replacing the air cleaner ele- ment
Replace the air cleaner element according
to the maintenance schedule in the “War-
ranty and Maintenance Booklet”. Under
extremely dusty conditions, replace it
more frequently. It is recommended that
you always use genuine SUBARU parts.B00309
B00018
Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters in-
take air but also stops flames if the
engine backfires. If the air cleaner
element is not installed when the en-
gine backfires, you could be burned.

Windshield washer fluid
If you spray washer fluid on the windshield
but the windshield washer fluid warning
light comes on or the supply of washer flu-
id drops, check the level of washer fluid in
the tank.
Washer fluid level gauge
Remove the washer tank filler cap, then
check the fluid level indicated by the level
gauge (attached to the inside of the cap).
If the level is near the “Low” mark, add flu- id until it reaches the “Hi” level on the level
gauge.
After adding fluid, make sure the wind-
shield washer fluid warning light has gone out.
Use windshield washer fluid. If windshield
washer fluid is unavailable use clean wa-
ter.
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 temper-
ature varies according to how much it is di-
luted, as indicated in the following table.
In order to prevent freezing of washer flu-
id, check the freezing temperatures in the
table above when adjusting the fluid con-
Never use engine coolant as washer
fluid because it could cause paint
damage.
