Involved in an AccidentYour vehicle has a fuel pump shut off
system. When the vehicle sustains an
impact in an accident, etc., the fuel pump
shut off system stops supplying the fuel in
order to minimize fuel leakage.
However, depending on the impact condi-
tions at the time of collision, the fuel pump
shut-off system may not operate.

that fuel has leaked on the ground,
do not try to rest art the engine. The
fuel system has been damaged and
is in need of repair. Immediately
contact the nearest automotive ser-
vice facility. We recommend that
you consult your SUBARU dealer.

Exterior Care
33210-1. Exterior Care■Washing
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 corro-
sive, accelerating the corrosion of under-
body components, such as the exhaust
system, fuel and brake lines, brake
cables, floor pan and fenders, and
suspension.
Thoroughly flush the underbody and
inside 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
parts, as they are particularly prone to
mud and sand buildup. Do not use a
sharp-edged tool to remove caked mud.
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
protruding 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 surface,
completely rinse off the detergent
with water. Otherwise, the cover
surface may be damaged.

– CONTINUED –
▼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 moldings, or cause
water to leak in to the vehicle.■Waxing and PolishingAlways 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 wher e 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 recommended.
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 a
compound or an incorrect polishing tech-
nique 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
specialist.
NOTEBe careful not to block the windshield
washer nozzles with wax when waxing
the vehicle.■ Cleaning Alloy WheelsPromptly wipe the alloy 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
washing device.
 Clean the vehicle (including the alloy
wheels) with water as soon as possible
when it has been splashed with sea water,
exposed to sea breezes, or driven on
roads treated with salt or other agents.
CAUTION
 Be careful not to damage brake
hoses, sensor harnesses, and
other parts when washing
suspension components. Be careful not to flush the engine
bottom for a long time. It may
cause damage of some electrical
parts.
CAUTION
Do not use any agents with organic
solvents on the surface of the bulb
assembly cover. However, if a pol-
ish 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.

11-1. Maintenance ScheduleU.S. models
The scheduled maintenance items
required to be serviced at regular intervals
are shown in the “Warranty and Mainte-
nance Booklet”. For details, read the
separate “Warranty and Maintenance
Booklet”.
Canada models
The scheduled maintenance items
required to be serviced at regular intervals
are shown in the “Warranty and Service
Booklet”. For details, read the separate
“Warranty and Service Booklet”.
Except for U.S. and Canada models
Some items of your vehicle are required to
be serviced at scheduled intervals. For
details about your maintenance schedule,
read the separate “Warranty and Mainte-
nance Booklet”.
11-2. Maintenance Precau -tionsWhen maintenance and service are
required, it is reco mmended that all work
be done by an authorized SUBARU
dealer.
If you perform maintenance and service
by yourself, you should familiarize your-
self with the information provided in this
section on general maintenance and
service for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
WARNING
 Always select a safe area when
performing maintenance on your
vehicle. Always be very careful to avoid
injury when working on the
vehicle. Remember that some of
the materials in the vehicle may
be hazardous if improperly used
or handled, for example, battery
acid.
 Your vehicle should only be
serviced by persons fully compe-
tent to do so. Serious personal
injury may result to persons not
experienced in servicing vehi-
cles. Always use the proper tools and
make certain that they are well
maintained. Never get under the vehicle
supported only by a jack. Always
use safety stands to support the
vehicle. Never keep the engine running in
a poorly ventilated area, such as a
garage or other closed areas. Do not smoke or allow open
flames around the fuel or battery.
This will cause a fire. Because the fuel system is under
pressure, replacement of the fuel
filter should be performed only by
your SUBARU dealer. Wear adequate eye protection to
guard against getting oil or fluids
in your eyes. If something does
get in your eyes, thoroughly wash
them out with clean water.
