&Synthetic oilYou must follow the oil and filter changing
intervals shown in the Warranty and
Maintenance booklet.NOTESynthetic oil of the grade and viscosity
noted in chapter 12 is the recom-
mended engine oil for optimum engine
performance. Conventional oil may be
used if synthetic oil is unavailable.
Cooling system
WARNING
.Never attempt to remove the
radiator cap until the engine has
been shut off and has cooled
down completely. Since the cool-
ant is under pressure, you may
suffer serious burns from a spray
of boiling hot coolant when the
cap is removed.
.Be careful of the rotating cooling
fan when the engine hood is
open. When the engine tempera-
ture is high, the cooling fan in the
engine compartment may oper-
ate when the ignition switch is in
the“ON”position, even if the
engine is stopped. Touching the
cooling fan while it is rotating
may result in injury.
CAUTION
.Vehicles are filled at the factory
with SUBARU Super Coolant that
does not require the first change
for 11 years/137,500 miles (11
years/220,000 km). Do not mix
this coolant with any other brandor type of coolant during this
period. Mixing with a different
coolant will reduce the life of the
coolant. Should it be necessary
to top up the coolant for any
reason, use only SUBARU Super
Coolant.
If the SUBARU Super Coolant is
diluted with another brand or
type, the maintenance interval is
shortened to that of the mixing
coolant.
.Do not splash the engine coolant
over painted parts. The alcohol
contained in the engine coolant
may damage the paint surface.

Alloy wheelsAlloy wheels can be scratched and da-
maged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
.When any of the wheels are removed
and replaced for tire rotation or to change a
flat tire, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose,
tighten it to the specified torque.
.Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
.Never let the wheel rub against sharp
protrusions or curbs.
.When wheel nuts, balance weights, or
the center cap is replaced, be sure to
replace them with genuine SUBARU parts
designed for alloy wheels.
Windshield washer fluid
CAUTION
Never use engine coolant as washer
fluid because it could cause paint
damage.Windshield washer fluid warning in-
dicator
When there is only a small amount of
washer fluid remaining, the windshield
washer fluid warning indicator will illumi-
nate. When this occurs, refill the washer
fluid as follows.
Remove the washer tank filler cap, then
add windshield washer fluid until it reaches
the“FULL”mark on the tank. If windshield
washer fluid is unavailable use clean
water.
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 tem-
perature varies according to how much it is
diluted, as indicated in the following table.

!Alternative engine oil
If the SUBARU approved oil is unavailable, the following alternative oil can be used.NOTE.Each quantity indicated here is only a guideline. The necessary quantity for replacement may differ slightly depending on
the temperature and other factors.
.In choosing an oil, you want the proper quality and viscosity, as well as one that will enhance 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. The following table lists the recommended viscosities and applicable temperatures.
.When adding oil, you may use different brands together as long as they are the same API classification and SAE viscosity
as those recommended by SUBARU.

replenishment is needed but should be
changed to 5W-30 synthetic oil at the
next oil change.
