Maintenance and service
Aluminum wheels (if equipped)Aluminum wheels can be scratched and
damaged easily. Handle them carefully to
maintain their appearance, performance,
and safety.
yWhen any of the wheels is removed and
replaced for tire rotation or to change a
flat, always check the tightness of the
wheel nuts after driving approximately 600
miles (1,000 km). If any nut is loose, tight-
en it to the specified torque.
y Never apply oil to the threaded parts,
wheel nuts, or tapered surface of the
wheel.
y Never let the wheel rub against sharp
protrusions or curbs.
y Be sure to fit tire chains on uniformly
and completely around the tire, otherwise
the chains may scratch the wheel.
y When wheel nuts, balance weights, or
the center cap is replaced, be sure to re-
place them with genuine SUBARU parts
designed for aluminum wheels.
Windshield washer fluidIf you spray washer fluid on the windshield
but the supply of washer fluid appears to
diminish, check the level of washer fluid in
the tank.
Use only those wheels that are
specified for your vehicle. Wheels
not meeting specifications could in-
terfere with brake caliper operation
and may cause the tires to rub
against the wheel well housing dur-
ing turns. The resulting loss of vehi-
cle control could lead to an acci-
dent.
Never use engine coolant as washer
fluid because it could cause paint
damage.

Washer fluid level gaugeRemove 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 or the “Full” mark on the tank.
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-
centration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the oneused previously, purge the old fluid from
the piping between the reservoir tank and
washer nozzles by operating the washer
for a certain period of time. Otherwise, if
the concentration of the fluid remaining in
the piping is too low for the outside tem-
perature, it may freeze and block the noz-
zles.

Never use engine coolant as washer
fluid because it could cause paint
damage.
Adjust the washer fluid concentra-
tion appropriately for the outside
temperature. If the concentration is
inappropriate, sprayed washer fluid
may freeze on the windshield and
obstruct your view, and the fluid
may freeze in the reservoir tank.

Maintenance and service
1) Cap
2) Upper level
3) Lower levelIt is unnecessary to periodically check the
battery fluid level or periodically refill with
distilled water.
However, if the battery fluid level is below
the lower level, remove the cap. Fill to the
upper level with distilled water.
FusesThe fuses are designed to melt during an
overload to prevent damage to the wiring
harness and electrical equipment. The
fuses are located in two fuse boxes.
One is located under the instrument panel
behind the cover on the driver’s seat side.
To remove the cover, pull it out.The other one is housed in the engine
compartment.
1) Fuse puller
2) Spare fuseThe fuse puller and spare fuses are stored
Never use more than 10 amperes
when charging the battery because
it will shorten battery life.

Never replace a fuse with one hav-
ing a higher rating or with material
other than a fuse because serious
damage or a fire could result.

in the main fuse box cover in the engine
compartment.1) Good
2) BlownIf any lights, accessories or other electri-
cal controls do not operate, inspect the
corresponding fuse. If a fuse has blown,
replace it.
1. Turn the ignition switch to the “LOCK”
position and turn off all electrical accesso-
ries.
2. Remove the cover.
3. Determine which fuse may be blown.
The back side of each fuse box cover and
the “Fuses and circuits” section in chapter
12 in this manual show the circuit for each
fuse.4. Pull out the fuse with the fuse puller.
5. Inspect the fuse. If it has blown, re-
place it with a spare fuse of the same rat-
ing.
6. If the same fuse blows again, this indi-
cates that its system has a problem. Con-
tact your SUBARU dealer for repairs.
Main fuseMain fuse boxThe main fuses are designed to melt dur-
ing an overload to prevent damage to the
wiring harness and electrical equipment.
Check the main fuses if any electrical
component fails to operate (except the
starter motor) and other fuses are good. A
melted main fuse must be replaced. Use
only replacements with the same speci-
fied rating as the melted main fuse. If a
main fuse blows after it is replaced, have
the electrical system checked by your
nearest SUBARU dealer.
