10-4 Appearance care
Corrosion protection
Your SUBARU has been designed and
built to resist corrosi on. Special materials
and protective finishes have been used on
most parts of the vehi cle to help maintain
fine appearance, strength, and reliable
operation. „ Most common causes of cor- rosion
The most common ca uses 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 accidents.
Corrosion is accelerated on the vehicle
when:
1. 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 pol-
lution.
2. It is driven in areas of high humidity, es-
pecially when temperatures range just
above freezing.
3. Dampness in certain parts of the vehi-
cle remains for a long time, even though other parts of the vehicle 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 regularly to prevent cor-
rosion of the body and suspension com-
ponents. Also, wash the vehicle promptly
after driving on any of the following surfac- es: y roads that have been salted to prevent
them from freezing in winter y mud, sand, or gravel
y 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 needassistance.
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. Oc-
casionally check under the mats to make
sure the area is dry.
Keep your garage dry. Do not park your
vehicle in a damp, poorly ventilated ga-
rage. In such a garage, corrosion can be
caused by dampness. If you wash the ve-
hicle in the garage or put the vehicle into
the garage when wet or covered with
snow, that can cause dampness.
If your vehicle is operated in cold weather
and/or in areas where road salts and other
corrosive materials are used, the door
hinges and locks, trunk lid lock, and hood
latch should be inspected and lubricated
periodically.

„Before checking or servicing
in the engine compartment
„When you do checking or ser-
vicing in the engine compart-
ment while the engine is run-ning
Engine hood
To open the hood:
1. If the wiper blades are lifted off the
windshield, return them to their original
positions.
2. Pull the hood release knob under the
instrument panel.yWear 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.
yDo not tamper wi th the wiring of
the SRS airbag system or seatbelt
pretensioner system, or attempt
to take its connectors apart, as
that may activate the system or it
can render it inoperative. The wir-
ing and connectors of these sys-
tems are yellow for easy identifi-
cation. NEVER use a circuit tester
for these wiring.
If your SRS airbag or seatbelt pre-
tensioner needs service, consult
your nearest SUBARU dealer.
y Always stop the engine and set
the parking brake firmly to pre-
vent the vehicle from moving.
yAlways let the engine cool down.
Engine parts b ecome very hot
when the engine is running and
remain hot for some time after the
engine is stopped.
y Do not spill engine oil, engine
coolant, brake fluid or any other
fluid on hot engine components.
This may cause a fire.
yAlways remove the key from the
ignition switch. When the ignition
switch is in the “ON” position, the
cooling fan may operate suddenly
even when the engine is stopped.
A running engine can be dangerous.
Keep your fingers, hands, clothing,
hair and tools away from the cooling
fan, belts and any other moving en-
gine parts. Removing rings, watch-
es and ties is advisable.

11 - 2 2 Maintenance and service
Automatic transmission fluid „Checking the fluid level
The automatic transmission fluid expands
largely as its temperature rises; the fluid
level differs according to fluid tempera-
ture. Therefore, there are two different
scales for checking the level of hot fluid
and cold fluid on the dipstick.
Though the fluid level can be checked
without warming up the fluid on the
“COLD” range, we recommend checking
the fluid level when the fluid is at operating
temperature. T Checking the fluid level when the
fluid is hot
Check the fluid level monthly.
1. Drive the vehicle se veral miles to raise
the temperature of the transmission fluid
up to normal operating temperature; 158 to 176 °F (70 to 80 °C) is normal.
2. Park the vehicle on a level surface and
set the parking brake.
3. First shift the selector lever in each po-
sition. Then shift it in the “P” position, and
run the engine at idling speed. 4-speed automatic transmission
1) Yellow handle
5-speed automatic transmission
1) Yellow handle1) HOT range
2) COLD range
3) Upper level
4) Lower level
4. Pull out the dipstick and check the fluid
level on the gauge. If it is below the lower
level on the “HOT” range, add the recom-
mended automatic transmission fluid up to
the upper level. T Checking the fluid level when the
fluid is cold
When the fluid level has to be checked
without time to warm up the automatic
transmission, check to see that the fluid
level is between the lower level and upper
level on the “COLD” range. If it is below
that range, add fluid up to the upper level.
Be careful not to overfill.1
