API Service label
1) Indicates the oil quality by API designations
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil
has fuel saving capabilities
In choosing an oil, you want the proper quality and vis-
cosity, as well as one that will add to fuel economy.
The following table lists the recommended viscosities
and applicable temperatures.
When adding oil, different brands may be used togeth-
er as long as they are the same API classification and
SAE viscosity as those recommended by SUBARU. SAE viscosity No. and applicable temperature
*: 5W-30 is preferred.
Engine oil viscosity (thickness) affects fuel economy.
Oils of lower viscosity pr ovide better fuel economy.
However, in hot weather, oil of higher viscosity is re-
quired to properly lubricate the engine. „ Recommended grade and viscosity

„ Oil grade and viscosityIf the vehicle is used in desert areas, in areas with very
high temperatures, or used for heavy-duty applica-
tions such as towing a trailer, use of oil with the follow-
ing grade and viscosities is recommended.

Cooling systemCooling system
Never attempt to remove the radiator 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 boiling hot coolant when the cap is re-
moved.
yThe cooling system has been filled at the fac-
tory 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 basis coolant. Use of improper
coolants may result in corrosion in the cooling
system. It is important to maintain protection
against freezing and corrosion, even if freezing
temperatures are not expected. Never mix dif-
ferent kinds of coolant. y Do not splash the engine coolant over paint-

ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
„ Hose and connections
„Hose and connectionsYour vehicle employs an electric cooling fan which is
thermostatically controlled to operate when the engine
coolant reaches a s pecific temperature.
If the radiator cooling f an 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 th e engine cooling syst em. It is recom-
mended that the cooling system and connections be
checked for leaks, damage, or looseness. „

TChecking the coolant level
1) “FULL” level mark
2) “LOW” level mark
Check the coolant level at each fuel stop.
1. Check the coolant level on the outside of the reser-
voir 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 re-
fill as required.

3. After refilling the reserve tank and the radiator, re-
install the caps and check that the rubber gaskets in-
side the radiator cap are in the proper position.
y Be careful not to spill engine coolant 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 it off.y Do not splash the engine coolant over paint-
ed parts. The alcohol contained in the engine
coolant may damage the paint surface.
T Changing the coolant
Always add genuine SUBARU cooling system condi-
tioner whenever the coolant is replaced.
Change the engine coolant and add genuine SUBARU cooling system cond itioner using the following proce-
dures according to the maintenance schedule in the
“Warranty and Maintenance Booklet”.
1. Remove the under cover.

2. Place a proper container under the drain plug and
loosen the drain plug.
Never attempt to remove the radiator 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 boiling hot coolant when the cap is re-
moved. 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.
NOTE (Turbo models)
The cap (without tabs) on top of the radiator does
not need to be removed. To add coolant, remove
the cap (with tabs) on th
e coolant tank on top of
the engine.

2) Fill up to here
4. Slowly pour the coolant and fill up to just below the
filler neck, allowing enough room to add genuine
SUBARU cooling system cond itioner in the radiator.
Add genuine SUBARU coolin g 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. Put the radiator cap back on and tighten firmly. At
this time, make sure that the rubber gasket in the radi-
ator cap is correctly in place.
7. Start and run the engine for more than five minutes
at 2,000 to 3,000 rpm.
8. 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.
9. Put the radiator cap and reservoir cap back on and

Air cleaner elementAir cleaner element
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 func tions 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 unnec-
essary to clean or wash the element. „ Replacing the air cleaner element

place it more frequently. It is recommended that you
always use genuine SUBARU parts.
