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.

Corrosion Protection
334Do not use detergent on the wheels
when they are hot, such as after driving or
parking in hot weather.■ Alloy Wheels (Vehicles with
Matte Painted Wheels)As matte painted wheels require different
cleaning methods than conventional alloy
wheels, be sure to observe the following.
For details, consult your SUBARU dealer.
 Remove dirt using water. If the wheels
are excessively dirty, use a sponge or soft
cloth dampened with a diluted neutral
detergent to remove the dirt.
 To prevent the matte paint from being
damaged, make sure to observe the
following precautions:
- Do not scrub or polish the wheels
using a brush or dry cloth.
- Do not use any wheel coatings or
abrasive detergents.
10-2. Corrosion ProtectionYour SUBARU has been designed and
built to resist corrosi on. Special materials
and protective finishes have been used on
most parts of the vehicle to help maintain
fine appearance, strength, and reliable
operation.■ Most Common Causes of
CorrosionThe most common causes of corrosion
are:
 The accumulation of moisture retaining
dirt and debris in body panel sections,
cavities, and other areas.
 Damage to paint and other protective
coatings caused by gravel and stone
chips or minor accidents.
Corrosion is accelera ted on the vehicle
when:
 It is exposed to road salt or dust control
chemicals, or used in coastal areas where
there is more salt in the air, or in areas
where there is considerable industrial
pollution.
 It is driven in areas of high humidity,
especially when temperatures range just
above freezing.
 Dampness in certain parts of the
vehicle remains for a long time, even though other parts of the vehicle may be

dry.
 High temperatures will cause corrosion
to parts of the vehicle which cannot dry
quickly due to lack of proper ventilation.
■ To Help Prevent CorrosionWash the vehicle regularly to prevent
corrosion of the body and suspension
components. Also, wash the vehicle
promptly after driving on any of the
following surfaces.
 Roads that have been salted to prevent
them from freezing in winter
 Mud, sand, or gravel
 Coastal roads
After the winter has ended, it is recom-
mended that the underbody be given a
very thorough washing.
Before the beginning of winter, check the
condition of underbody components, such
as the exhaust system, fuel and brake
lines, brake cables, suspension, steering
system, floor pan, and fenders. If any of
them are found to be rusted, they should
be given an appropriate rust prevention
treatment or should be replaced. Contact
your SUBARU dealer to perform this kind
of maintenance and treatment if you need
assistance.
Repair chips and scratches in the paint as
soon as you find them.

Tires and Wheels
363
Maintenance and Service11
– CONTINUED –
■Wheel BalanceEach wheel was correctly balanced
when your vehicle was new, but the
wheels will become unbalanced as
the tires become worn during use.
Wheel imbalance causes the
steering wheel to vibrate slightly at
certain vehicle speeds and detracts
from the vehicle’s straight-line
stability. It can also cause steering
and suspension system problems
and abnormal tire wear. If you
suspect that the wheels are not
correctly balanced, have them
checked and adjusted by your
SUBARU dealer. Also have them
adjusted after tire repairs and after
tire rotation.
NOTEThe suspension system is
designed to hold each wheel at a
certain alignment (relative to the
other wheels and to the road) for
optimum straight-line stability
and cornering performance.■ Wear Indicators1) New tread
2) Worn tread3)
Tread wear indicator
Each tire incorporates a tread wear
indicator, which becomes visible
when the depth of the tread grooves
decreases to 0.063 in (1.6 mm). A tire must be replaced when the

tread wear indicator appears as a
solid band across the tread.
NOTEFor safety, inspect the tire tread
regularly and replace the tires
before their tread wear indicators
become visible.
CAUTION
Loss of correct wheel align-
ment causes the tires to wear
on one side and reduces the
vehicle’s running stability.
Contact your SUBARU dealer
if you notice abnormal tire
wear.
12 3
B00327
WARNING
When a tire’s tread wear indi-
cator becomes visible, the tire
is worn beyond the accept-
able limit and must be
replaced immediately. With a
tire in this condition, driving at
high speeds in wet weather
can cause the vehicle to
hydroplane. The resulting loss
of vehicle control can lead to
an accident.
