Appearance care/Exterior care
Exterior care
&Washing
CAUTION
. When washing the vehicle, the
brakes may get wet. As a result,
the brake stopping distance will
be longer. To dry the brakes,
drive the vehicle at a safe speed
while lightly pressing the brake
pedal to heat up the brakes.
. Do not wash the engine compart-
ment and areas adjacent to it. If
water enters the engine air intake
or electrical parts, it will cause
engine trouble or a malfunction
of the power steering.
. When washing inner fenders,
underbody, bumpers and pro-
truding objects such as exhaust
pipes and exhaust finishers, be
careful to prevent injuries from
contacting sharp ends.
. Do not use any organic solvents
when washing the surface of the
bulb assembly cover. However, if
a detergent with organic solvents
is used to wash the cover sur-
face, completely rinse off the
detergent with water. Otherwise, the cover surface may be da-
maged.
. Outback: Since your vehicle is
equipped with a rear wiper, auto-
matic car-wash brushes could
become tangled around it, dama-
ging the wiper arm and other
components. Ask the automatic
car-wash operator not to let the
brushes touch the wiper arm or
to fix the wiper arm on the rear
window glass with adhesive tape
before operating the machine.
NOTE
When having your vehicle washed in
an automatic car wash, make sure
beforehand that the car wash is of
suitable type.
The best way to preserve your vehicle’ s
beauty is frequent washing. Wash the
vehicle at least once a month to avoid
contamination by road grime.
Wash dirt off with a wet sponge and plenty
of lukewarm or cold water. Do not wash
the vehicle with hot water and in direct
sunlight.
Salt, chemicals, insects, tar, soot, tree
sap, and bird droppings should be washed
off by using a light detergent, as required. If you use a light detergent, make certain
that it is a neutral detergent. Do not use
strong soap or chemical detergents. All
cleaning agents should be promptly
flushed from the surface and not allowed
to dry there. Rinse the vehicle thoroughly
with plenty of lukewarm water. Wipe the
remaining water off with a chamois or soft
cloth. Wear rubber gloves and use a hand
brush when washing down underbody,
inner fenders and suspension to effec-
tively remove mud and dirt off.
!
Washing the underbody
Chemicals, salts and gravel used for
deicing road surfaces are extremely cor-
rosive, accelerating the corrosion of un-
derbody components, such as the exhaust
system, fuel and brake lines, brake
cables, floor pan and fenders, and sus-
pension.
Thoroughly flush the underbody and in-
side of the fenders with lukewarm or cold
water at frequent intervals to reduce the
harmful effects of such agents.
Mud and sand adhering to the underbody
components may accelerate their corro-
sion.
After driving off-road or on muddy or
sandy roads, wash the mud and sand off
the underbody.
Carefully flush the suspension and axle
10-2

parts, as they are particularly prone to
mud and sand buildup. Do not use a
sharp-edged tool to remove caked mud.
CAUTION
.Be careful not to damage brake
hoses, sensor harnesses, and
other parts when washing sus-
pension components.
. Be careful not to flush the engine
bottom for a long time. It may
cause damage of some electrical
parts.
! Using a warm water washer
. Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle.
. Do not wash the same area continu-
ously.
. If a stain will not come out easily, wash
by hand. Some warm water washers are
of the high temperature, high pressure
type, and they can damage or deform the
resin parts such as mouldings, or cause
water to leak into the vehicle.
& Waxing and polishing
Always wash and dry the vehicle before
waxing and polishing.
Use a good quality polish and wax and
apply them according to the manufac-
turer ’s instructions. Wax or polish when
the painted surface is cool.
Be sure to polish and wax the chrome trim,
as well as the painted surfaces. Loss of
wax on a painted surface leads to loss of
the original luster and also quickens the
deterioration of the surface. It is recom-
mended that a coat of wax be applied at
least once a month, or whenever the
surface no longer repels water.
If the appearance of the paint has dimin-
ished to the point where the luster or tone
cannot be restored, lightly polish the
surface with a fine-grained compound.
Never polish just the affected area, but
include the surrounding area as well.
Always polish in only one direction. A
No. 2000 grain compound is recom-
mended. Never use a coarse-grained
compound. Coarser grained compounds
have a smaller grain-size number and
could damage the paint. After polishing
with a compound, coat with wax to restore
the original luster. Frequent polishing with
acompoundoranincorrectpolishing
technique will result in removing the paint layer and exposing the undercoat. When
in doubt, it is always best to contact your
SUBARU dealer or an auto paint specia-
list.
CAUTION
Do not use any agents with organic
solvents on the surface of the bulb
assembly cover. However, if a polish
or wax with organic solvents is
applied to the cover surface, com-
pletely wipe off the polish or wax.
Otherwise, the cover surface may be
damaged.
NOTE
Be careful not to block the windshield
washer nozzles with wax when waxing
the vehicle.
&
Cleaning aluminum wheels
. Promptly wipe the aluminum wheels
clean of any kind of grime or agent. If dirt
is left on too long, it may be difficult to
clean off.
. Do not use soap containing grit to
clean the wheels. Be sure to use a neutral
cleaning agent, and later rinse thoroughly
with water. Do not clean the wheels with a
stiff brush or expose them to a high-speed
