CAUTION
Never use engine coolant as washer
fluid because it could cause paint
damage.
In order to prevent freezing of washer
fluid, check the freezing temperatures in
the table above when adjusting the fluid
concentration to the outside temperature.
If you fill the reservoir tank with a fluid with
a different concentration from the one
used 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
thepipingistoolowfortheoutside
temperature, it may freeze and block the
nozzles.
CAUTION
. Adjust the washer fluid concen-
tration appropriately for the out-
side temperature. If the concen-
tration is inappropriate, sprayed
washer fluid may freeze on the
windshield and obstruct your
view, and the fluid may freeze in
the reservoir tank.
. State or local regulations on
volatile organic compounds may
restrict the use of methanol, a
common windshield washer anti-
freeze additive. Washer fluids
containing non-methanol anti-
freeze agents should be used
only if they provide cold weather
protection without damaging
your vehicle ’s paint, wiper blades
or washer system.
Replacement of wiper blades
Grease, wax, insects, or other materials
on the windshield or the wiper blade
results in jerky wiper operation and streak-
ing on the glass. If you cannot remove the
streaks after operating the windshield
washer or if the wiper operation is jerky,
clean the outer surface of the windshield
(or rear window) and the wiper blades
using a sponge or soft cloth with a neutral
detergent or mild abrasive cleaner. After
cleaning, rinse the windshield and wiper
blades with clean water. The windshield is
clean if beads do not form when you rinse
the windshield with water.
CAUTION
. Do not clean the wiper blades
with gasoline or a solvent, such
as paint thinner or benzine. This
will cause deterioration of the
wiper blades.
. When you wish to raise the
passenger-side wiper arm, first
raise the driver-side wiper arm.
Otherwise, the passenger-side
wiper assembly and driver-side
wiper assembly will touch each
other, possibly resulting in
scratches.

The other one (main fuse box) is housed
in the engine compartment.
1) Spare fuses
The spare fuses are stored in the main
fuse box cover in the engine compart-
ment.
The fuse puller is stored in the main fuse
box in the engine compartment. To pick up
the fuse puller, pull it out while pinching
the puller head with your fingers.
1) Good
2) Blown
If any lights, accessories or other electrical
controls do not operate, inspect the
corresponding fuse. If a fuse has blown,
replace it.
1. Turn the ignition switch to the“LOCK”/
“OFF ”position and turn off all electrical
accessories.
2. Remove the fuse box cover.
3. Determine which fuse may be blown.
Look at the back side of each fuse box
cover and refer to “Fuses and circuits”
F 12-10.
4. Pull out the fuse with the fuse puller.
5. Inspect the fuse. If it has blown,
replace it with a spare fuse of the same
rating.
6. If the same fuse blows again, this
indicates that its system has a problem.

&Engine oil
For the checking, adding and replacing procedure or other details, refer to “Engine oil ”F 11-11.
NOTEThe procedure for changing the engine oil and oil filter should be performed by a properly-trained expert. It is recommended
that you have this service performed by your SUBARU dealer.
! Approved engine oil
Always use the SUBARU approved engine oil. For further details, please contact your SUBARU dealer.
If the approved engine oil is unavailable, use the alternative engine oil described on the next page.
! Alternative engine oil
If the SUBARU approved oil is unavailable, the following alternative oil can be used.
NOTE
. Each quantity indicated 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, different brands may be used together as long as they are the same API classification and SAE viscosity
as those recommended by SUBARU.
