Exterior care Washing
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 luke-
warm or cold water. Do not wash the vehicle with hot
water and in direct sunlight.
Salt, chemicals, insects, tar, soot 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 al-
lowed to dry there. Rinse the vehicle thoroughly with
plenty of lukewarm water. Wipe the remaining water
off with a chamois or soft cloth. NOTE When having your vehicle washed in an auto- matic car wash, make sure beforehand that thecar wash is of suitable type. If the vehicle is
equipped with a rear/roof spoiler, it may be dam-aged by car wash brushes or other equipment.CAUTION
When washing the vehicle, the brakes may
get wet. As a result, the brake stopping dis-
tance will be longer. To dry the brakes, drive the vehicle at a safe speed while lightly press-ing the brake pedal to heat up the brakes. Do not wash the engine compartment and
area adjacent to it. If water enters the engineair intake, electrical parts or the power steer-
ing fluid reservoir, it will cause engine trouble
or faulty power steering respectively.
Washing the underbody
Chemicals, salts and gravel used for deicing road
surfaces are extremely corrosive, accelerating the
corrosion of underbody 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 in-
tervals to reduce the harmful effects of such agents.
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 continuously.

Corrosion protection
Your SUBARU has been designed and built to resist
corrosion. Special materials and protective finishes
have been used on most parts of the vehicle to help
maintain fine appearance, strength, and reliable op- eration. Most common causes of corrosion
The most common causes of corrosion are:
1. The accumulation of moisture retaining dirt and
debris in body panel sections, cavities, and other
areas.
2. Damage to paint and other protective coatings caused by gravel and stone chips or minor acci- dents.
Corrosion is accelerated on the vehicle when:
1. It is exposed to road salt or dust control chemi-
cals, or used in coastal areas where there is more
salt in the air, or in areas where there is considerable industrial pollution.
2. It is driven in areas of high humidity, especially
when temperatures range just above freezing.
3. Dampness in certain parts of the vehicle remains
for a long time, even though other parts of the ve-
hicle may be dry. 4. High temperatures will cause corrosion to parts
of the vehicle which cannot dry quickly due to lack
of proper ventilation.
To help prevent corrosion
Wash the vehicle frequently. If you drive on salted
roads in the winter or if you live in a coastal area,
you should flush the underbody with fresh water fre-
quently.
After the winter has ended, it is recommended that
the underbody be given a very thorough washing.
Before the beginning of winter, check the condition of underbody components, such as the exhaust sys- tem, 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 per-
form this kind of maintenance and treatment if you need assistance. Repair chips and scratches in the paint as soon as you find them.
Check the interior of the vehicle for water and dirt
accumulation under the floor mats because that
could cause corrosion. Occasionally check under

Drive belts
The alternator, power steering pump, and air condi-
tioner compressor depend on drive belts. Satisfacto-
ry performance requires that belt tension be correct.

Power steering fluid Checking the fluid level
The power steering fluid expands greatly as its tem-
perature rises; the fluid level differs according to
fluid temperature. Therefore, the reservoir tank has
two different checking ranges for hot and coldfluids.
Check the power steering fluid level monthly.
1. Park the vehicle on a level surface, and stop theengine.
2. Check the fluid level of the reservoir tank.
When the fluid is hot after the vehicle has been run: Check that the oil level is between “HOT MIN ” and
“ HOT MAX ” on the surface of the reservoir tank.
When the fluid is cool before the vehicle is run: Check that the oil level is between “COLD MIN ” and
“ COLD MAX ” on the surface of the reservoir tank.
3. If the fluid level is lower than the applicable “MIN”
line, add the recommended fluid as necessary tobring the level between the “MIN” and “MAX” line.

If the fluid level is extreme low, it may indicate pos-
sible leakage. Consult your SUBARU dealer for in-spection.
WARNING
Be careful not to burn yourself because the fluid may be hot.
CAUTION
When power steering fluid is being added,
use only clean fluid, and be careful not to al- low any dirt into the tank. And never use dif-
ferent brands together. Avoid spilling fluid when adding it in the
tank.
